RESOLUTION NO. 7685 RESOLUTION OF THE COUNCIL OF THE CITY OF PALO ALTO CERTIFYING THE ENVIRONMENTAL IMPACT REPORT FOR THE SAND HILL CORRIDOR PROJECTS, ADOPTING A MITIGATION MONITORING PROGRAM, AND MAKING CERTAIN FINDINGS The Council of the City of Palo Alto does RESOLVE as follows: SECTION 1. Background. The City Council of the City of Palo Alto ("City Council") finds, determines and declares as follows: A. In 1992 Stanford Management Company (herein,"Stanford" or "the applicant") submitted applications for development approvals for four major development projects, hereafter described individually as the Stanford West Apartments project, Stanford West Senior Housing project, Stanford Shopping Center Expansion and Sand Hill Road Extension and Related Roadway Improvements project. ("SHRE/RRI project"), referred to collectively herein as the Sand Hill Corridor projects. After further discussions with City representatives Stanford withdrew its applications and engaged in an extended public outreach process, including neighborhood meetings, community meetings and two Saturday workshops. In November 1994, Stanford submitted revised development proposals for the Sand Hill Corridor projects incorporating changes made in response to the public outreach process. B. The City issued a Notice of Preparation for the Environmental Impact Report for the Sand Hill Corridor projects in April 1995, and duly filed the Notice of Preparation with the State Clearinghouse on April 14, 1995. Comments on the NOP were received from interested public agencies for a 30 -day period. Copies of this notice were duly mailed to all identified responsible agencies, trustee agencies and other public agencies known to be interested in the projects. Public scoping meetings for the EIR- were conducted by the City in the City of Palo Alto City Council chambers on. June 13, 1995, and in the City of Menlo Park City Council chambers on June 15, 1995. Preparation of a Draft EIR ("DEIR") for the projects was commenced in June 1995. Following commencement of the DEIR City staff and consultants engaged to prepare the DEIR engaged in extensive consultation with public agencies and many private persons interested or having special knowledge in subjects relevant to the projects, and duly considered the comments, information, opinions and recommendations received during consultation in preparing the DEIR. C. During preparation of the DEIR for the proposed Sand Hill Corridor projects, City staff determined that the relocation of Pasteur Drive would create a small parcel of unincorporated land under the jurisdiction of the County of Santa Clara which should be annexed the City. This Pasteur Drive Parcel Annexation has been 1 970626 lac 0031595 • evaluated as a fifth project purposes of the EIR, and is analyzed in Section 5.1 of the DEIR. D. After extensive internal review, the DEIR was released for public review on June 18, 1996. A notice of the availability of the Draft EIR was published in the Palo Alto Weekly on June 12, 1996. Notices of availability and/or copies of the DEIR were also mailed to the State Clearinghouse, to all responsible agencies and to all other persons who requested notice of the Draft EIR. A 45 - day period for public review and comments on the Draft EIR was also commenced on June 18, 1996, and closed on August 1, 1996. Copies of the DEIR were also made available for public review at the Palo Alto Planning Department, the Menlo Park Planning Department, Palo Alto Public Libraries, and the Menlo Park Public Library. E. The City Planning Commission conducted public hearings to review the Draft EIR and to receive public comments on the Draft EIR on July 24, July 31, and August 1, 1996. The Planning Commission conducted further deliberations on the proposed projects and on the DEIR on August 3, August 7, August 8, August 29, September 3, October 30, 1996, and January 8, 1997. At the recommendation of the Planning Commission the subsequently prepared Final EIR ("FEIR") was expanded to include further evaluation of possible alternatives and other information concerning the projects. F. During the public comment period the City received written and oral comments on the DEIR and on the projects from numerous persons and organizations. The City prepared written responses to all written and oral comments received during the public comment period on the Draft. EIR. These written responses appear in Volumes 7, Volume 8, and Chapter 12 of Volume 6 of the FEIR. These responses to comments address and fully respond to all significant environmental issues raised in comments on the DEIR. Although not required by CEQA, the responses to comments also address and respond to many comments raised by members of the public concerning social, technical, economic and planning issues related to the projects. G. Volumes 6, 7, and 8 of the FEIR were completed and released for public review on January 10, 1997. Pursuant to Public Resources Code section 21092.5, the City provided copies of the City's responses to comments to each public agency which commented on the DEIR more than ten days prior to commencement of public hearings on the projects by the City Council on January 27, 1997. H. The City Council held duly noticed public hearings on the Sand Hill Corridor projects and on the EIR on January 27 and 30; February 4, 6, 8, 11 and 26; March 3, 5, 11, 12, 17, 18 and 26; and April 8 and 29, 1997. The Council received oral testimony and written comments from over 200 individuals and organizations. After the close of the public hearing, the Council continued its deliberations on the Sand Hill Corridor projects and the EIR at further public meetings on May 27 and 28, and June 2 and 30, 1997. 2 9706261ac 0031595 • • I. - At the close of the Council deliberations at its meeting of June 2, 1997, the Council invited further written public comment on the project, to and including June 9, 1997. Over sixty (60) comments were received during that period. J. In the course of City evaluation of the proposed Sand Hill Corridor projects, Stanford agreed to undertake a number of modifications to the proposed projects to implement suggested mitigation measures or proposed conditions of approval, to implement recommendations of the Planning Commission and Architectural Review Board, and to improve various project design features. Changes made to the proposed projects after preparation of the DEIR but before release of Volume 8 of the FEIR are described and evaluated in Chapter 11 of the FEIR. In addition, following review and evaluation of the projects the City Council requested and the applicant agreed to a number of additional changes and modifications to the proposed projects to further implement recommended mitigation measures, to implement project alternatives and to further improve or enhance project features and design. These changes are summarized and evaluated in the "Summary of Current Project Revisions," ("Summary") which is included in and constitutes an integral component of the certified Final EIR ("EIR"). The Summary was prepared to describe and review the modifications and to ensure that a complete description of all elements of each approved project was included for future reference in the EIR. The Summary also was prepared to review the changes and consider whether any of the changes constitute significant new information within the meaning of Public Resources Code section 21092.1 and CEQA Guidelines section 15088.5. The analysis performed for the Summary confirmed that the changes to the project will not result in any new significant environmental impacts not previously evaluated in the EIR, will not result in substantial worsening of any environmental impact previously analyzed in the EIR, and do not constitute or require new mitigation measures or alternatives warranting recirculation of the EIR pursuant to CEQA Guidelines section 15088.5. SECTION 2. Certification Having fully reviewed the information contained in the EIR and all its components, and considered the EIR in light of all additional information received during public hearings on the proposed projects, including staff reports, oral and written testimony received from other public agencies and members of the public, additional information known from reports, studies, proceedings and other matters of record included or referenced in the administrative record of these proceedings, the Council hereby finds, declares and certifies that: A. The Final EIR ("EIR") consists of and includes the following documents: 1. Stanford/Sand Hill Road Corridor Projects Draft EIR, Volumes 1-3; 3 970626 lac 0031595 • • 2. Stanford/Sand Hill Road Corridor Projects Draft SIR, Technical appendices, Volumes 4 and 5; 3. Volumes 6, 7, and 8, which include: Introduction; List of Comments and Transcripts; Applicant -initiated Text Changes; - Frequently Referenced Consolidated Responses; - Response to Major Issues Planning Commission; Summary of Text Changes; Raised by the Letters 1 through 157, and written responses to each comment contained therein; - Transcripts from Menlo Park Planning Commission and City Council hearings and Palo Alto Planning Commission hearings, and written responses to each comment made at those hearings; and 4. The Summary of Current Project Revisions. B. The EIR is intended to and does constitute the full and complete EIR for each of the five individual projects evaluated in the EIR, including: 1. Stanford West Apartments project; 2. Stanford West Senior Housing project; 3. Stanford Shopping Center Expansion project; 4. Sand Hill Road Extension, Widening and Related Roadway Improvements project; and 5. Pasteur Drive Parcel Annexation project. The EIR is intended for use in all discretionary approvals granted by all public agencies for the project, including approval of a Development Agreement pertaining to the approved projects and all discretionary approvals considered by responsible agencies including the City of Menlo Park. C. The Draft and Final EIR were prepared by City staff and City consultants and have at all times reflected the 4 970626 lac 0031595 independent review and judgment of the City on all matters stated in the Draft EIR and Final EIR. D. The EIR has been completed in compliance with all applicable provisions of the California Environmental Quality Act. SECTION 3. Mitigation Monitoring Program. Pursuant to Public Resources Code section 21081.6, the City has prepared a comprehensive Mitigation Monitoring Program ("MMP") which provides for implementation, monitoring and enforcement of all conditions and mitigation measures adopted to mitigate environmental impacts of the approved projects. The MMP is set forth in Exhibit "A" to this Resolution and is hereby adopted and approved by the Council. The Council, in adopting the MMP, declares that the recitation of the mitigation measures in the MMP is intended to be the same as in the EIR, as may be revised or adopted by. reference by the conditions of approval. Therefore, it is the intent of the Council that in the event a mitigation. measure or condition is worded differently in the MMP than in the conditions of approval, including those mitigation measures adopted by reference, the conditions shall control. The Monitoring and Reporting Procedures in the MMP-are intended to implement, not to modify, the conditions of approval, and the Procedures shall be interpreted accordingly, in a manner that does not diminish or add to the requirements imposed on the applicant. SECTION 4. Consideration of Environmental Impacts, Mitigation Measures and Alternatives. 1. Findings Pursuant to Public Resources Code section 21081. The findings of the Council for each project are set forth in Exhibits "B" through "F" to this Resolution and are by this reference fully incorporated herein. The Council finds, declares and certifies that each of the statements, conclusions and findings set forth in the attached findings are based on substantial evidence contained or referenced in the administrative record and reflects the considered judgment of the Council on each of the issues addressed in the findings. 2. Review and Consideration of Impacts. The Council has considered all information contained in the EIR, as well as all other relevant information received in the course of evaluation and review of the proposed projects, concerning all significant and potentially significant environmental impacts and cumulative impacts of the five proposed Sand Hill Corridor projects. 5 970626 lac 003! 595 3. Mitigation Measures and Alternatives. In reviewing the proposed Sand Hill Corridor projects and granting discretionary approvals for each project and the related Development Agreement the Council has also fully considered each of the mitigation measures identified for the environmental impacts of the projects and has considered each of the project alternatives identified in the EIR for each of the proposed Sand Hill Corridor projects. Pursuant to Public Resources Code section 21081(a), the Council has made specific findings concerning the conditions, changes and mitigation measures which have been incorporated into the projects. In adopting these conditions, changes and mitigation measures, the language of some of the mitigation measures recommended by the EIR has been modified as set forth in the conditions of approval for purposes of clarity and consistency to enhance enforceability, or to strengthen their provisions. The Council finds that each of the mitigation measures that has been so modified will be as effective, or more effective, than the measures as originally proposed. In addition, the Council has rejected or revised some of the mitigation measures recommended by the EIR in whole or in part, as set forth in the conditions of approval. The Council's reasons for doing so are described in the Council's findings for each project. The Council has also evaluated the comparative merits of the alternatives to the projects described in the EIR, and pursuant to Public Resources Code section 21081, further made specific findings concerning these alternatives to the projects, and adopted, adopted in part, or rejected those alternatives as set forth in the conditions of approval and the findings. The Council's reasons for adopting, adopting in part, or rejecting those alternatives are described in the Council's findings for each project. The Council finds that the alternatives, changes, mitigation measures and conditions of approval adopted in connection with the approved projects avoid or mitigate the adverse environmental impacts of each of the projects to the maximum extent feasible. 4. Alternatives Considered. The Council also finds that the EIR has evaluated a reasonable range of alternatives for each of the proposed Sand Hill Corridor projects. The Council has considered the information in Chapter 6.3 of the DEIR, entitled Summary of Rejected Alternatives, comments on the Draft EIR and the responses to those comments contained in the FEIR, and additional information received during City review and evaluation of the proposed projects or known from reports, studies, proceedings and other matters of record included or referenced in the administrative record of these proceedings. The Council concludes that the EIR evaluates a range of reasonable alternatives to the projects, or the location of the projects, which would feasibly accomplish most of the basic objectives of the projects. The Council further finds that there are no additional 6 970626 lac 0031595 •. feasible alternatives to any of the proposed projects which were unreasonably excluded from consideration in the EIR. 5. Statements of Overriding Considerations. Pursuant to Public Resources Code section 21081(b), the Council has further considered all of the significant environmental impacts of the projects which have not been or cannot be avoided or reduced to less than significant levels by the mitigation measures and conditions of approval adopted in connection with the projects. The Council has further balanced these remaining significant adverse impacts of each project against the potential public, social, economic and other benefits of the project and determined that these significant environmental effects are acceptable in light of specific overriding benefits which justify approval of each of the projects on the terms and conditions approved by the Council. The Council's individual Statements of Overriding Considerations for approval of each of the Sand Hill Corridor projects are set forth in Exhibits "G" through "J" to this Resolution, and by this reference fully incorporated herein. The Council further finds, declares and certifies that each of the findings and conclusions set forth in these Statements of Overriding Considerations is based on substantial evidence contained or referenced in the administrative record and reflects the considered judgment of the Council on each of the issues addressed in the Statement of Overriding Considerations. 6. Environmental Effects Found Less Than Significant. The Council has also considered the information contained in the EIR and all other information received during evaluation and consideration of the projects with respect to any asserted additional environmental effects of the projects not evaluated in the EIR. The Council finds that based on all evidence received, there are no additional significant or potentially significant adverse environmental effects which may result from any of the projects which have not been identified and evaluated in the EIR. The Council has further considered the evaluation in the EIR of additional potential environmental impacts which were determined not to be significant or potentially significant, and finds that these impacts were correctly analyzed and determined to be less than significant in the EIR. The Council has not received any substantial evidence warranting a change in the conclusions stated in the EIR with respect to any of the impacts identified as less than significant in the EIR. SECTION 5. New Information Received During the Public Review Process. In the course of continuing environmental review of the proposed Sand Hill Corridor projects, the City has been presented with various information which was not contained in the DEIR for the proposed projects and which has been contended by some commenters to constitute significant new information constituting grounds for revising and recirculating the EIR for further public 7 970626 lie 0031595 • • review and comment pursuant to Public Resources Code section 21092.2 and CEQA Guidelines section 15088.5. The Council has considered all new or additional information, and all information alleged to be significant new information received since preparation and circulation of the DEIR, including all comments and responses to comments on the DEIR, various changes made to the projects, and all comments and other information since release of the responses to comments, and finds that none of the new or allegedly new information warrants further revision of the EIR or recirculation of the EIR for further public review and comment. None of the new or additional information appearing after preparation of the DEIR indicates that: (1) new significant environmental impacts not previously considered in the DEIR would result from any of the projects; (2) there will be a substantial increase in severity of any impact previously evaluated in the DEIR; (3) new feasible mitigation measures or alternatives considerably different than those analyzed in the DEIR has become available and has not been adopted by the applicant; or (4) the DEIR was so fundamentally inadequate or conclusory that meaningful public comment was precluded. With respect to certain specific new or additional information which has been received since preparation of the DEIR or has been contended to constitute a basis for revision and recirculation of the EIR, the Council makes the following specific findings: A. Other Alternatives and Mitigation Measures 1, Refined Off -site Housing Alternative. At the request of the City Planning Commission, Section 13.1 of the Final EIR evaluated a "Refined Off -site Stanford West Apartments Alternative" consisting of relocation of the Stanford West Apartments project to new sites adjacent to Stanford's Hoover Pavilion and in El Camino Park. In its findings on the Stanford West Apartments the Council has determined that this suggested alternative is not a feasible alternative. The Council also finds that the longstanding City, County and Stanford land use plans and policies are not consistent with development of a major apartment project on the proposed alternative sites, rendering this alternative clearly infeasible. The Council, therefore, finds that this alternative was correctly excluded from the reasonable range of alternatives for the Stanford West Apartments project considered in the DEIR and that exclusion of this alternative did not preclude meaningful public comment on the DEIR. 2. Refined 50% Stanford Shopping Center Expansion Alternative. At the request of the Planning Commission Section 13.2 of the Final EIR evaluated a "Refined 50% Stanford Shopping Center Expansion Alternative" which includes reduced commercial development of approximately 80,000 square feet, relocation of certain buildings proposed in the original project, and relocation of parking structures originally proposed along Sand Hill Road to the Quarry Road side of the Stanford Shopping Center. This alternative is not substantially different than alternatives 8 970626 lac 0031595 • • suggested in the DEIR and does not include any mitigation measures or alternative measures which have not been accepted by the applicant. Relocation of proposed parking structures from Sand Hill Road to Quarry Road was discussed and recommended as a mitigation measure (4.2-1(1)) in the DEIR and agreed to by the applicant prior to completion of the DEIR. The approved project includes one new parking structure, on Quarry Road, along with retention of the existing parking structure on Quarry Road at Arboretum Road. Relocation of the new parking structure to Quarry Road also will not result in new impacts or impacts substantially more severe than analyzed in the DEIR. While this change to the proposed project will add an additional parking structure and increase the overall bulk of parking structures on Quarry Road, this location is not considered visually sensitive by the Council and the impacts of locating one expanded parking structure along Quarry Road were evaluated and appropriate mitigation measures identified in the DEIR. The impacts of the additional parking structure will be mitigated through implementation of measures evaluated in the DEIR and will in any case result in a net decrease in the visual impacts associated with the parking structures. Other impacts of the refined alternative are substantially similar to the 50% Reduced Density Alternative considered in the DEIR. The relocation of some commercial buildings in the refined alternative will not have any substantial effect on overall project impacts justifying revision or recirculation of the EIR. 3. Alpine Road Alternative: In scoping for the EIR and in public comments on the DEIR the City received requests that it consider construction of a new roadway between Alpine Road and areas affected by the Sand Hill Corridor development projects as an alternative to the widening of Sand Hill Road. In its findings on the Sand Hill Road Extension and Related Road Improvements project the Council found that this alternative is patently infeasible. The Council finds that this suggested alternative does not represent a reasonable or feasible alternative to the Sand Hill Road widening for the reasons stated in the Council's findings on alternatives for the SHRE/RRI project and that exclusion of this suggested alternative from the DEIR therefore did not preclude meaningful public comment or informed decision making on feasible alternatives to the SHRE/RRI project. Renewed requests for consideration of this alternative following circulation of the DEIR did not constitute new information for purposes of requiring revisions and recirculation of the EIR. B. Changed Circumstances 1. University Circle Area in East Palo Alto ( i.e., whiskey Gulch): After release of the FEIR the City of East Palo Alto publicly announced that it was seeking proposals for redevelopment of the University Circle (Whiskey Gulch) area of East Palo Alto adjacent to U.S. Highway 101. Prior to preparation of the DEIR the City of East Palo Alto was consulted and informed City staff that no applications for development or other foreseeable plans for development of the University Circle area were known at that time. At the present time no entitlements for new development 9 970626 lac 0031595 • • in the University Circle area have been issued and no application for development in the University Circle area has been received by the City of East Palo Alto. East Palo Alto has entered into an "Exclusive Right to Negotiate" ("ERN") agreement with a potential developer. The Council finds that based on the information known at the time the DEIR was released for public circulation, the potential redevelopment of University Circle was not a reasonably foreseeable project for purposes of assessing potential cumulative impacts of the Sand Hill Corridor projects. In addition, the cumulative impact analysis in the EIR relies primarily on a summary of projections contained in adopted general plans and regional plans, as authorized by CEQA Guidelines section 15130(b)(1)(b). Adjustment of this cumulative impact analysis to account for additional specific potential projects identified after completion of the FEIR is not required to provide a legally adequate and useful overall assessment of potential cumulative impacts. The Council also has not received any substantial evidence that a University Circle redevelopment proposal, if approved, will causeanyimpacts of the Sand Hill Corridor projects to become substantially more severe than predicted in the DEIR and FEIR or will result in a sufficient change in circumstances affecting the Sand Hill corridor projects as to result in significant new impacts not evaluated in the DEIR or FEIR. Further, while cumulative future traffic conditions in City areas south of El Camino are an important concern of the Council, revision of the EIR to include speculative information on the potential redevelopment of University Circle would not provide new information substantially affecting the EIR's analysis of impacts,' mitigation measures and alternatives for the proposed Sand Hill Corridor projects. 2. New Traffic Information During public hearings on the proposed Sand Hill Corridor projects the Council received new traffic information in the form of traffic counts for certain area intersections obtained after preparation of,the Draft EIR. Analysis of this additional traffic information by City staff, however, indicates that while this data shows increases in traffic counts at a number of area intersections in comparison with traffic counts at these intersections in the most recent preceding years, the current traffic counts are generally consistent with long term trends previously documented and relied on in preparation of the EIR. The observed increased counts at some intersections are fully consistent with a combination of normal fluctuations in annual traffic counts, and near -term traffic increases associated with reversal of economic conditions in the region which resulted in lower traffic counts in preceding years. The additional traffic information received by the Council does not indicate that any substantial change in overall area or regional traffic conditions has occurred or that any of the traffic data or conclusions of the EIR are invalid or unreliable in light of new information. 10 970626 Jac 0031595 • C. Changes in the Proposed Projects Throughout the course of environmental review the applicant, City staff and consultants, City Planning Commission and City Council have considered and adopted various changes to the proposed projects intended to reduce potential adverse effects and increase compatibility of the projects with City plans, goals and policies. These changes are consistent with the mandate that "CEQA compels an interactive process of assessment of environmental impacts and responsive project modification which must be genuine. It must be open to the public, premised upon full and meaningful disclosure of the scope, purposes, and effect of a consistently described project, with flexibility to respond to unforseen insights that emerge from the process." (County of Inyo v. City of Los Angeles (1984) 160 Cal.App.3d 1178, 1185.) The specific changes incorporated into each project are discussed in Chapter 11 and the "Summary of Current Project Revisions" incorporated into the EIR. The Council has considered the evaluation of these changes and potential effects and consequences of these changes set forth in these sections of the EIR and fully agrees with and adopts this analysis. Based on the information and conclusions set forth in Chapter 11 and the Summary of Current Project Revisions, considered in light of all additional relevant information in the administrative record, the Council finds that none of these changes made in the projects will: (1) result in significant environmental impacts not identified and considered in the Draft EIR; (2) cause any environmental impact previously discussed in the Draft EIR to become substantially more severe than anticipated in the Draft EIR; (3) require the adoption of mitigation measures or consideration of further project alternatives considerably different than those previously discussed in the Draft EIR. The changes made in the proposed projects in the course of environmental review have in many cases been intended to implement mitigation measures or incorporate elements of project alternatives previously suggested in the Draft EIR. In the course of considering and adopting these various changes to the projects, the City also has not identified any further or additional feasible mitigation measures or alternatives which would further substantially reduce any adverse environmental effects of any of the proposed projects and which have not been voluntarily incorporated into the projects by the applicant. D. Additional Issues Raised in Public Comments 1. Traffic Modeling In comments on the Draft EIR and in the course the Council's public hearings, the Council has received extensive comments on the traffic modeling methods and data utilized in the EIR. The Council has fully considered the traffic studies contained in the EIR, the comments on the traffic modeling and the data and conclusions reported in the EIR received from members of 11 970626 lac 0031595 the public and other public agencies, and the responses to these comments in the Final EIR and in staff reports and other information received from City staff. The Council recognizes that all predictions and estimations of future traffic conditions necessarily rely on modeling and forecasting techniques, and that the accuracy, reliability or appropriateness of any model, as well as the accuracy of data and any assumptions relied on in modeling, may be the subject of dispute among experts as well as substantial disagreement among lay persons. The Council finds, however, that based on all the available evidence, the modeling methods relied on in preparation of the EIR represents the most appropriate, reliable and accurate model available for analyzing the complex traffic conditions and effects analyzed in the EIR. The Council has not been presented with any credible or persuasive evidence indicating that the model or the data and conclusions produced by the model are inadequate or improper. The Council also has not received any credible or persuasive evidence that traffic impacts of the Sand Hill Corridor projects will be substantially more severe than predicted in the EIR or that future background traffic conditions will be substantially different than predicted in the EIR. 2. Theater Development at Stanford Shopping Center During Council hearings on the proposed projects Stanford announced that it was considering the possibility of leasing space in the Stanford Shopping Center for operation of a movie theater or theaters. Construction and operation of a movie theater or theaters in the Stanford Shopping Center would require discretionary City approval in the form of a Conditional Use Permit ("CUP"). No proposal to develop theater facilities on the Stanford Shopping Center has been made to Stanford, no plans for a theater have been formulated, and no application for a CUP for such facilities has been received. Preliminary analysis by City staff indicates that a movie theater or theaters could, depending upon the timing of film showings, generate more peak hour vehicle trips than equivalent amount of conventional retail development. However, the overall increase in peak hour traffic would be small in relation to traffic generated by the Stanford Shopping Center as a whole and could not have any significant effect on traffic conditions on area roadways or intersections. Potential peak hour traffic impacts associated with theater operation could also be avoided by timing the beginning and ending of film showings to avoid peak traffic conditions; this mitigation measure could be implemented voluntarily by the applicant or by conditions imposed in the CUP. The Council has not been presented with any substantial evidence that development and operation of theater facilities, if such a proposal is submitted, would result in any new or substantially more severe environmental effects than the effects of the Stanford Shopping Center Expansion project identified in the EIR. SECTION 6. This Council has reviewed and considered the information and evidence in the record relating to the consistency of the projects with the goals, policies and other provisions of the Comprehensive Plan, including, but not limited to, the 12 970626 lac 0031595 discussion -of consistency issues set forth in the EIR, the written and oral reports provided by staff, and written and oral comments on the issue, and having also considered the contents of the Comprehensive Plan, and the reports, studies and proceedings related thereto, this Council, as the body charged with adopting, interpreting and applying the goals, policies and provisions of the Comprehensive Plan, finds that each project as conditioned and approved is fully consistent with all applicable goals, policies and other provisions of the Comprehensive Plan as amended. SECTION 6. Record of Proceedings. The documents comprising the record of proceedings in this matter are located in the offices of the City of Palo Alto Department of Planning and Community Environment. The custodian of these documents is the Director of Planning and Community Environment, 250 Hamilton Avenue, 5th Floor, Palo Alto, California, or his designee. SECTION 7. This resolution shall be effective upon the date of its adoption.

A MMP is required for each proposed project because the EIR for the projects has identified significant adverse impacts, and mitigation measures have been identified to mitigate those impacts. In addition to EIR mitigation measures, the MMP includes the Conditions of Approval, including the Tentative Subdivision Map Conditions of Approval that the City of Palo Alto Planning and Community Environment Department and the Planning Commission have recommended. The Tentative Sub- division Map Conditions are located in a separate section at the end of this document. The numbering of the individual mitigation measures follows the numbering sequence as found in the EIR All revisions to mitigation measures that were necessary as a result of responding to public comment and incorporating staff -initiated revisions, as identified in the Final EIR, have been incorporated into this MMP. The Conditions of Approval are listed with those mitigation measures that most closely relate, with the exception of the Tentative Subdivision Map Conditions which are at the end of the document. Adoption of the MMP(s) shall occur prior to, or concurrently with, adoption of the proposed project(s) for which the program has been developed. PURPOSE OF MMP The purpose of a MMP includes the following: • Ensure that mitigation measures are implemented; • Provide feedback to agency staff and decision makers about the effectiveness of the mitigation measures; lPLAMP ,Anmcsmu. D t awe-DFMDAPI TRO WPD 1 .tune 26, 1997 Mitigation Monitoring . gram, Conditions of Approval and Tentative Subdivision Map Conditions of Approval • Provide learning opportunities for improving mitigation measures on future projects; and • Identify the need for enforcement action before irreversible environmental damage occurs. RELATIONSHIP OF MMP TO EIR The recitation of the mitigation measures in the MMP is intended to be the same as in the EIR, as may be revised or adopted by reference by the conditions of approval. Therefore, it is the intent of the Council that in the event a mitigation measure or condition is worded differently in the MMP than in the conditions of approval, including those mitigation measures adopted by reference, the conditions shall control. The Monitoring and Reporting Procedures in the MMP are intended to implement, not modify, the conditions of approval, and the Procedures shall be interpreted accord- ingly, in a manner that does not diminish or add to the requirements imposed on the applicant. With respect to the column in the Program labeled "Monitoring Responsibility," the City of Palo Alto, as lead agency, will be the final decision -maker as to whether a condition relating to work over which the City of Palo Alto has control or authority, has been adequately fulfilled. However, in making such determinations, the City will give due deference to other entities, as listed in that column, with respect to work required to be done within the jurisdiction or area of expertise of those entities. To the extent a condition or mitigation relates to work or approvals over which the City of Palo Alto has no control or authority, and another governmental agency, within whose jurisdiction the work or approvals would be performed or processes, decides not to authorize or approve, or delays unreasonably the work or approvals implementing the condition or mitigation, the City of Palo Alto will not require it to be fulfilled.

As part of its consideration of the mitigation plan, the City of Palo Alto shall receive comment from CCRS and CRMP (which includes the City of Menlo Park) as to the adequacy and completeness of the plan. Riparian restoration can be integrated with the tree replacement mitigation (4.7-i) and planned for o pen space or setback areas along San Francisquito Creek onsite, such as abandoned golf course and other sites where native riparian vegetation is currently sparse or non-existent. Areas where riparian vegetation has been temporarily removed for construction at the bridge widening site shall also be replanted with native riparian species. If more area is req uired to fulfill the native tree and riparian habitat replacement mitigation requirement , it can be accomplished in vacant areas left after removal of non-native vegetation. Candidate non-native tree removal and native riparian tree planting sites include those areas mapped as " urban" or "eucalyptus" along San Francisquito Creek in Figure 4,7-1. Other creek restoration measures should be developed in coordination with CDFG, CCRS, and CRMP (which inclu des the City of Menlo Park) to allow for increased structural diversity in the channel through strategic placement of logs and other natural features. The riparian mitigation effort should be coordinated with restoration of the grassland area (Mitigation Mea sure 4.7-3) to increase values of both habitats.

The EIR has been prepared for five projects including the Stanford West Apartments, Stanford West Senior Housing, Stanford Shopping Center Expansion, Sand Hill Road Extension and Related Roadway Improvements ("SHRE/RRI") projects, referred to collectively herein as the "Sand Hill Corridor projects," and the Pasteur Drive Parcel Annexation project. These projects are described in Chapter 3 of the EIR, and include, as approved by the Council, the changes and revisions described in Chapter 11 and in the "Final Summary of Project Changes" made a part of the EIR by the certifying resolution. Pursuant to Section 21081(a) of the Public Resources Code, the Council has considered each environmental impact of the Stanford West Apartments project identified in the EIR, and each of the mitigation measures and project alternatives evaluated in the EIR. The Council's detailed findings for each significant environmental impact or potentially significant environmental impact identified in the EIR are set forth below. Each significant or potentially significant environmental impact identified in the EIR is listed in bold. Those mitigation measures adopted or partially adopted by the Council are also numbered in bold. The' Council's reasons for rejection or part-ial rejection of certain mitigation measures and reasons for selection among alternative potential mitigation measures are described where appropriate. The Council's reasons for rejecting specific alternatives to the project identified in the EIR are stated in Part II of these findings. 1 970702 lac 0031587 PART I CHANGES AND MITIGATION MEASURES ADOPTED TO REDUCE IMPACTS 4.1 LAND USE 4.1-5 Implementation of the proposed projects, in conjunction with cumulative development within the Sand Hill Road Corridor, would result in a change in character in the area. The EIR concludes that there are no feasible mitigation measures available which will substantially reduce the identified significant land use impacts and that these impacts are therefore unavoidable. The Council also finds that due to the magnitude of change in use and character of the existing vacant Stanford West Apartments site, the identified impacts are significant. The conditions for approval of the Stanford West Apartments project, however, incorporate a number of mitigation measures which will lessen the overall severity of these impacts by reducing visual impacts, preserving grassland habitat area, protecting the San Francisquito Creek riparian zone from intrusion and providing for planting of new and replacement trees on the project site. These measures are discussed more fully in sections of these findings pertaining to mitigation of visual, transportation, noise and biological impacts. Despite these measures, however, the impact remains significant. 4.2 VISUAL QUALITY/LIGHT AND GLARE 4.2-1 The proposed projects would result in major visual changes within the Sand Hill Road corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-1(b), as revised at p. 14-3 of the EIR, requires that final landscaping plans provide for large scale, shrub/understory planting between Sand Hill Road and apartment parking lots to augment screening of the site from Sand Hill Road. In addition to adoption of mitigation measure 4.2-1(b), changes were made in the project design during the environmental review process which partly implemented recommended mitigation measure 4.2-1(a). Specifically changes discussed at pp. 11-1 - 11-5 of the FEIR were made in the project design to reduce impacts on Governor's Lane and to open a potential view corridor. The project as approved, however, will include construction of a child care facility in the area formerly designated for construction of these apartment buildings. The child care facility will not significantly impact the Governor's Lane corridor, but will reduce the view corridor benefit in this area. 2 970702 lac 0031587 The Council finds that the foregoing changes made to the project and the adoption of mitigation measure 4.2-1(b) will lessen somewhat the project's impact on views from the Sand Hill Road corridor, but will not reduce the impact to a less than significant level. The adopted changes and mitigation measure, in conjunction with other features of the project design, will somewhat reduce the visual impact of development and loss of existing views by preserving limited open space views along Sand Hill Road and by screening buildings with foliage, thereby reducing the viewer's perception of a continuous wall of development. These measures, however, will not overcome the major unavoidable change in visual character and loss of views of open space and the San Francisquito Creek riparian area which would necessarily result from any substantial development on the site. This impact therefore remains significant. The Council also finds that it is not desirable to further mitigate the visual impacts by redesigning the project to create additional view corridors as recommended in mitigation measure 4.2-1(a). Given that the developed portions of the project site will be extensively screened from Sand Hill Road by foliage as provided in mitigation measure 4.2-1(b), the actual visual benefit of additional view corridors would be slight. Redesign of the project to include view corridors would also result in loss of additional apartment units and/or loss of the child care facilities required by the Development Agreement for the project and Condition 14.A of the project conditions of approval. In view of the City's existing severe shortage of rental housing units and need for child-care services, neither of these losses is acceptable as a tradeoff for the slight visual benefit of additional view corridors. The Council finds that the Stanford West Apartment project is consistent with the Palo Alto Comprehensive Plan's Scenic Highways section as amended. The Council finds that the location of the required covered parking in Sand Hill Road's twenty-five foot special setback will, because of the design of the parking areas and the extensive amount of existing and proposed landscaping, be compatible with the scenic highway designation of Sand Hill Road. The EIR identified the need for a stopping place for the public to use to view the scenic environment. Provision of a roadside stopping place would be incompatible with the arterial design of Sand Hill Road. Main Street will allow members of the public opportunities to use stopping places to view the area, including the historic Governor's Lane and the riparian backdrop of San Francisquito Creek. Views of Governor's Lane and the riparian backdrop will also be possible for those traveling along Sand Hill Road, especially at locations west of the intersections of Sand Hill Road with Vineyard Lane and with Pasteur Drive. 4.2-3 Views of pedestrians and bicyclists on the pedestrian path/bikeway from the creek crossing to Sand Hill Road would be greatly altered from views of open space to a developed, urbanized environment. Mitigation measure 4.2-3 provides that the final landscape plans for the project shall include sufficient density, height, and 3 970702 lac 0031587 • • proximity of proposed tree plantings to the east of the pedestrian path to minimize views to project buildings in the long term. Tree plantings shall be designed to achieve canopy closure above and to the east of the pedestrian path. The Council finds that adoption of this measure will lessen the project's impact on views from the pedestrian/bicycle bridge, but will not reduce the impact to a less than significant level. The required landscaping will substantially screen views of the Stanford West Senior Housing project to the east and therefore provide some visual relief from the overall change of visual character of the area. This measure will not, however, eliminate the substantial visual impact associated with development of the Stanford West Apartments project, and the impact therefore remains significant. 4.2-8 Visual disturbance from construction of the proposed projects could have temporary adverse visual impacts. Mitigation measure 4.2-8 requires that on -site staging and storage of construction equipment and materials should be minimized to reduce visual disturbance during construction. Equipment and material storage that does occur on -site should be visually screened. Graded areas should be watered regularly to minimize fugitive dust., Construction should be staged and scheduled to minimize the duration of disturbance in each affected viewshed. The Council finds that adoption of this mitigation measure will lessen the adverse visual impact of project construction, but will not reduce this impact to a less than significant level. The adopted mitigation measure will limit the duration and visibility of construction equipment and grading activities on the site, but will not eliminate the significant visual impact necessarily associated with major construction activities on the site. This impact therefore remains significant. 4.2-9 The proposed projects, in conjunction with cumulative development in the Sand Hill Road Corridor, could adversely affect the visual character of the corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-9 recommends that mitigation measures 4.2-1(a-1) be implemented for all the Sand Hill Road Corridor Projects, including the Stanford West Apartments project. The Council has adopted or partially adopted the provisions of project -specific mitigation measures 4.2-1(a)-(1) pertaining to the Stanford West Apartments project, except as noted in connection with the findings for Impact 4.2-1. The Council finds that the adoption of these mitigation measures will lessen the project's contribution to cumulative visual impacts from development of the Sand Hill Road corridor for reasons previously stated in relation to each adopted mitigation measure, but that these measures collectively will not reduce the project's contribution to cumulative visual impacts to a less than significant level. 4 970702 lac 0031587 i • The Council has adopted or partially adopted the provisions of mitigation measures 4.2-Z(a)-(l) as they pertain to the Stanford West Apartments project. The Council finds that the adoption of these mitigation measure will lessen the project's contribution to cumulative visual impacts from development of the Sand Hill Road corridor for reasons previously stated in relation to each adopted mitigation measure, but that these measures collectively will not reduce the project's contribution to cumulative visual impacts to a less than significant level. The additional project -specific mitigation measures recommended in mitigation measure 4.2-9 have been adopted, partially adopted, or rejected as stated in the findings for the Stanford West Senior Housing, Stanford Shopping Center expansion and Sand Hill Road Extension and Related Roadway Improvements projects. To the extent these measures have been adopted, they collectively will reduce but not eliminate the significant adverse cumulative visual impacts of the Sand Hill Corridor projects. This cumulative impact therefore remains significant. The Council recognizes that future development, to the extent allowed in the Sand Hill Corridor, will continue to add to the significant cumulative visual impacts associated with the approved projects. 4.2-11 The proposed projects, in conjunction with cumulative development, could adversely alter views from the pedestrian/bicycle bridge crossing San Francisquito Creek to Menlo Park. Mitigation measure 4.2-11 provides that the applicant shall provide landscape screening of the Children's Health Council facilities from the bike path. The Council finds that adoption of this mitigation measure will lessen the project's contribution to cumulative impacts on views from the pedestrian/bicycle bridge, but will not reduce the project's contribution nor the cumulative impact to a less than significant level. The required landscaping will substantially screen views of the Children's Health Council, therefore reducing the amount of buildings and paved area immediately visible from the bridge crossing area. The visual screening, however, will not reduce the visual impact of new development associated directly with the Stanford West Apartments and resulting change in visual character of the area site. The cumulative impact therefore remains significant. 4.2-13 The proposed projects, in conjunction with cumulative development, could generate light and glare from buildings and roadways that could have adverse effects on nearby residents and on -coming drivers along Sand Hill Road. Mitigation measure 4.2-13 provides that interior and exterior light sources associated with all of the approved Sand Hill Road Corridor projects, including the Stanford West Apartments project, 5 970/02 lac 0031587 • • shall be.shielded or directed in such a manner as to prevent visibility of the light sources and to eliminate light spillover beyond the perimeter of the proposed project. Specific measures recommended in accordance with section 18.64.030 of the Palo Alto Municipal Code include the following: (a) Exterior light fixtures on the housing buildings should be mounted no higher than 15 feet at the rear of the buildings. (b) Lighting of the building exterior and parking lot should be of the lowest intensity and energy use adequate for its purpose. (c) Unnecessary continued illumination, such as illuminated signs, should be avoided. (d) Timing devices should be considered for exterior and interior lights in order to minimize light glare at night without jeopardizing security. The Council finds that adoption of this measure will lessen the project's contribution to potential cumulative light and glare impacts to insignificance. This measure has also been incorporated into the conditions of approval for other approved Sand Hill Corridor projects. The adopted mitigation measure will have the effect of eliminating substantial spillover of light from each individual project and will therefore lessen the potential cumulative impact to insignificance. 4.3 CULTURAL RESOURCES 4.3-1 Implementation of the proposed projects would result in damaging effects on important historic and/or prehistoric archaeological resources. Mitigation measure 4.3-1(b) requires that prior to development the applicant shall conduct a data recovery program on all areas in which construction is believed to have a potential to result in significant archaeological impacts. The program shall consist of an initial phase of intensive subsurface archaeological testing meeting minimum standards specified in the EIR. Significant resources encountered shall be subject to recovery, evaluation and preservation as provided in mitigation measure 4.3-1(c). All work shall be subject to review and monitoring by an independent archaeologist engaged by the City. Following construction, mitigation measure 4.7-3(f) shall be implemented; this measure requires that mowing instead of discing cf grassland areas be used to provide necessary fire clearances, thus avoiding damage to near -surface artifacts. The Stanford West Apartment management shall post signs and enforce rules to minimize disruption of the archaeological area by residents or others. Mitigation measure 4.3-1(c) requires manual excavation and recovery of archaeological resources from any areas encountered during construction which are determined to hold important archaeological resources and requires the recovery, evaluation and 6 970702 lac 0031521 • preservation of these resources. The measure also provides for ongoing monitoring of construction activities in areas potentially containing archaeological resources and for preparation of further detailed plans to ensure protection and recovery of any significant resources encountered in such areas. The plans shall include (a) provisions for artifact cataloging, analysis, and curation; (b) identification and coordination with most -likely Native American descendants concerning monitoring and reburial of Native American remains, if any are encountered; (c) plans for preparation of technical reports; (4) analysis and preservation of artifacts and documentation and analysis of non -recoverable site features. All of the foregoing shall be performed in accordance with current scientific and professional standards. Mitigation measure 4.3-1(d), as modified in p. 14-9 of the EIR, provides that any mechanical excavation for underground utility lines in Level 1 avoidance areas shall be conducted under the supervision of an archaeologist. If mechanical excavation is determined to pose a threat to archaeological resources, excavation will be conducted manually. Removed soil shall be screened and any artifacts recovered will be analyzed, reported and curated as provided in mitigation measure 4.3-1(c). Mitigation measure 4.3-1(e) limits the placement of paved bicycle or pedestrian paths or light -duty roads and specifies additional measures to ensure that no impacts will result from placement or construction of these paths or roads in areas likely to contain archaeological resources. Mitigation measure 4.3-1(f) provides that construction activities involving substantial ground disturbance (greater than 12" in depth) near any known archaeological site shall be subject to monitoring. This measure also applies to all construction in all Level 1 archaeological areas which have not been shown to contain significant resources during initial Phase 1 testing. The discovery of archaeological resources during monitoring will trigger evaluation and recovery of the resources, if appropriate, in accordance with mitigation measures 4.3-1(g) and 4.3-1(c). Mitigation measure 4.3-1(g) provides that if previously unidentified cultural resources are discovered during construction, work shall cease in the immediate area until qualified archaeologists assess the significance of the resources and make mitigation recommendations (e.g., manual excavation of the immediate area), if warranted. Mitigation measure 4.3-1(h) requires the applicant and contractors to comply with the requirements of Section 7050.5(b) of the California Health and Safety Code if possible Native American burials or remains are found during construction. This code section requires that a Native American Most Likely Descendant (determined in consultation with the Native American Heritage Commission) be notified within 24 hours and arrangements made for appropriate reburial. This and related sections of the Public 7 970702 lac 0031587 • • Resources Code also provide that remains shall be protected from further construction work or vandalism pending reburial. The Council finds that adoption of these mitigation measures, taken together with the project design, will lessen the project's impacts to historic and prehistoric archaeological resources to a less than significant level. The adopted mitigation measures are collectively intended to supplement the principal form of mitigation incorporated into the design of the project, which is physical avoidance and in -site preservation of archaeological resources. The site plans for the Stanford West Apartments project have taken into account the known presence of substantial archaeological resources on portions of the site nearest to San Francisquito Creek. No development is approved in areas presently known to contain important archaeological resources. Within the areas believed to have a potential to contain important archaeological resources (the Level 1 avoidance zone), development of buildings and landscaping is limited to approximately 52,000 square feet. In most areas the site plans provide a buffer (Level 2 avoidance zone) between development and known or probable archaeological resources. Within the Level 1 and Level 2 avoidance areas subject to development, the adopted mitigation measures provide for complete recovery, preservation and study of all significant resources encountered in accordance with current scientific,and professional standards, thus ensuring that there will be no loss of scientific or historical value of these resources. Mitigation measure 4.3-1(h) also provides for reburial of Native American remains, if any, encountered during development. Because adopted mitigation measures will avoid any net loss of historic or scientific value of presently unknown important archaeological resources found on the site, the net impact of the project will not be significant. Rejected Mitigation Measure In approving the project, the Council has not adopted alternate mitigation measure 4.3-1(a) discussed in the EIR. Mitigation measure 4.3-1(a) would have required the project to be redesigned if feasible to avoid all areas designated as Level 1 avoidance areas and to reduce development in Level 2 avoidance areas. A revised site plan shown as Figure 4.3-2 in the EIR indicates that implementation would result in elimination of approximately 80 residential units from the project. The Council finds that mitigation measure 4.3-1(a) is infeasible as it relates to impacts to archaeological resources on the site because the measure would eliminate housing units from the project without resulting in any substantial reduction in net overall impacts of the project on archaeological resources. There is disagreement between Stanford's archaeologists and the City's EIR consultants as to the extent of probable significant archaeological resources on the site. Stanford's archaeologist believes that the development plan avoids all areas of known or probable significant resources. The EIR has taken a more conservative approach and designated a Level 1 sensitivity area 8 970702 lac 0031587 • • which includes additional areas not presently known to contain significant archaeological resources but which the EIR consultants believe have a potential to include such resources. The development plans limit development (buildings and landscaping) to approximately 52,000 square feet of area which the EIR identifies as having the potential to hold important archaeological resources. Most or all of this area has been previously subjected to surface disturbance in the form of agricultural ploughing. Potential impacts of development in this area and on all other areas of the site have been reduced to less than significant levels by the adoption of mitigation measures 4.3 -1(b) -(h). Because it is presently uncertain that the development plan will result in disturbance of any significant archaeological resources and because alternate measures are available and have been implemented to reduce all potential impacts to insignificance, implementation of mitigation measure 4.3-1(a) is not necessary to avoid significant impacts on archaeological resources from the project and cannot be justified in light of the loss of housing units which would result from implementation of the measure. 4.3-2 Implementation of the proposed projects could result in loss of the Governor's Lane historic landscape feature. Mitigation measure 4.3-2(a) provides that fencing or other appropriate protection shall be installed prior to construction to protect Governor's Lane from direct physical impacts to this historic resource. Existing viable eucalyptus trees in Governor's Lane shall be preserved; those determined not to be viable may be removed and replaced with the species being used along the entire Governor's Lane alignment (e.g., Sycamore). Mitigation measure 4.3-2(b), which is directed at preserving the historical context of Governor's Lane corridor, has been partially adopted as a condition of project approval. The adopted provisions (subparagraphs (3) and (4)) of this mitigation measure provide that (a) the proposed parking lane which parallels Sand Hill Road shall be terminated at the western edge of the Governor's Lane corridor, thus avoiding intrusion and disruption of the continuity of the restored Governor's Lane, and (b) that the pedestrian pathways which bisect the Governor's Lane corridor shall be paved using materials consistent with the historical nature of the corridor (e.g. decomposed granite, cobblestone, brick, etc.). The Council finds that adoption of these measures will lessen the project's impacts on the Governor's Lane historic feature to a less than significant level. The effect of these measures will be to preserve the location, visual impression and existing trees of this historic landscape feature with a minimum of direct physical disturbance. Other measures incorporated into the project call for planting of additional suitable trees to restore and enhance this historic feature and ensure its permanent retention on the site. 9 970702 lac 0031587 Rejected Mitigation Measures Mitigation measures 4.3-1(a) and 4.3-2(b) provide for specific additional measures to reduce impacts to the Governor's Lane corridor, specifically (a) portions of buildings which intrude into the Governor's Lane corridor shall be removed, and (b) Main Street shall be reconfigured the wrap around the northeastern terminus of Governor's Lane. These additional mitigating measures have not been incorporated into the conditions of approval adopted by the Council. The Council finds that these additional measures are infeasible because they cannot be accomplished without substantial disruption of the proposed development plan and would jeopardize the project's ability to provide needed child care facilities. While the residential buildings originally proposed to be constructed in the Governor's Lane have been relocated, the revised project plans call for construction of child care facilities in this area. The child care facilities constitute an essential element of the approved project. In light of the mitigation measures which have been adopted, the location of the child care facilities in this area will not have a significant impact on the historic value of Governor's Lane. Reconfiguration of Main Street to fully avoid Governor's Lane would require redesign of the project and would result in unacceptable loss of recreational open space for the project. These rejected mitigation measures are not necessary to reduce impacts on Governor's Lane to less than significant levels and therefore cannot be justified in terms of their net overall effects on the project. 4.3-6 The proposed projects, in conjunction with other cumulative development projects in the San Francisquito Creek drainage, could result in damage or destruction of important prehistoric and historic cultural resources. Mitigation measure 4.3-6 recommends that all planning jurisdictions within the San Francisquito Creek drainage implement cultural resource testing and data recovery measures, similar to those described in Mitigation measure 4.3-1 for projects involving development of sensitive cultural resource sites. The Council has adopted the recommended mitigation measure for the Stanford West Apartments project and all other approved Sand Hill Corridor projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level and will also lessen the cumulative impact of the Sand Hill Corridor projects collectively to a less than .3ignificant level. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects within the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is 10 970702 lac 0031587 within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative impact from future projects on archaeological resources is presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which. the recommended measures will be implemented or the extent to which these measures, if implemented, will -lessen or avoid potential cumulative visual impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.4 TRANSPORTATION 4.4-2 Bicycle and/or pedestrian access and safety could be affected by development of the proposed projects. Mitigation measure 4.4-2(a) requires that the final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed and approved by the City's Chief Transportation Official to ensure the circulation system will function as a part of regional or inter -city bicycle and pedestrian connections. Mitigation measure 4.4-2(e) provides that for five years following project construction, the project applicant will fund an annual review of reported traffic accident data at the Sand Hill Road/I-280 interchange to determine whether a significant increase in bicycle/auto conflicts has occurred. If an increase is. documented, the applicant will work with Caltrans, the City of Menlo Park and San Mateo County to design and obtain funding for safety improvements required to minimize these conflicts. The Council finds that adoption of these measures will lessen the project's impacts on pedestrian and bicycle travel to insignificance. The project as proposed includes provisions to preserve and improve existing bicycle and pedestrian routes through the project site. The adopted mitigation measure will ensure that the final design ensures safe bicycle and pedestrian access to and through the site to local and regional bicycle and pedestrian paths, including those being implemented in conjunction with other elements of the Sand Hill Corridor projects. These measures also require Stanford to work with responsible agencies to eliminate safety problems resulting from increased bicycle and vehicle traffic at the Sand Hill Road/I-280 intersection if such problems are determined to exist in the future. 4.4-7 Development of the proposed projects could degrade the level of service of study area intersections, and contribute to increased intersection delay. The studies and analysis performed for the EIR demonstrate that the project, either singly or in conjunction with other 11 970702 lac 0031587 • approved: Sand Hill Corridor projects, will not have significant adverse effects on levels of service at most intersections near the project site. The EIR concluded, however, that changes and increases in traffic patterns resulting from the Sand Hill Road Corridor projects collectively will result in significant adverse changes in traffic conditions at a total of seven area intersections, specifically: Arboretum Road/Galvez Street - El Camino Real/Page Mill Road - El Camino Real/Ravenswood Avenue El Camino Real/Valparaiso Avenue/Glenwood Avenue Junipero Serra Blvd./Alpine Road/Santa Cruz Avenue Middlefield Road/Willow Road Sand Hill Road/Santa Cruz Avenue The EIR concludes that traffic from the Stanford West Apartments project, considered in light of the concurrent approval of the modified Sand Hill Road Extension, Widening and Related Roadway Improvements project, will result in significant adverse changes at a total of four area intersections, specifically: Arboretum Road/Galvez Street El Camino Real/Page Mill Road Sand Hill Road/Santa Cruz Avenue - Middlefield Avenue/Willow Road The conditions of approval nevertheless require the applicant to contribute to all of the following mitigation measures. Arboretum Road/Galvez Street: Mitigation measure 4.4-7(a) provides that the applicant shall install a traffic signal or other appropriate traffic control device(s) at the intersection of Arboretum Road/Galvez Street, and shall be required to pay the full cost of the improvement. This measure shall be implemented when the intersection satisfies appropriate signal warrants as determined by the Chief Transportation Official. In the event that the City and the applicant determine that use of a traffic circle or "roundabout" will provide for the same or better LOS and safety as a traffic signal, the traffic circle may be constructed at the applicant's expense instead of a traffic signals or other traditional traffic control device(s). El Camino Real/Page Mill Road: Mitigation measure 4.4-7(b) provides that the applicant shall contribute a fair share of the costs of the following planned improvements: - Add a southbound right turn lane. - Add a westbound right turn lane. Add a northbound right turn lane, and extend the westbound left turn lane by 100 feet. 12 970702 lac 0031387 • • These measures should be implemented when the intersection approaches LOS F, as evaluated through periodic monitoring to be carried out by the applicant on behalf of the City. Sand Hill Road/Santa Cruz Avenue: Mitigation measure 4.4-7(c) provides that the applicant shall contribute a fair share to the following improvements to this intersection mandated by the Menlo Park General Plan: Widen Sand Hill Road to add second eastbound left turn lane. Widen Sand Hill Road to lane. add second westbound left turn Modify signal phasing. The applicant shall also pay the costs of installing an exclusive right turn lane on the northbound approach of Santa Cruz Avenue and providing dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. Conditions of approval 1.c and 12 for the Sand Hill Road Extension and Related Roadway Improvements project, as adopted by. condition of approval 2.h for this project, provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, with respect to any improvements within that jurisdiction, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue: Mitigation measure 4.4-7(d) requires the applicant to pay a fair share of the costs of the following improvements to the Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue intersection mandated by the Menlo Park General Plan or recommended in the EIR: Widen northbound approach to add exclusive right turn lane. Install an additional southbound left -turn lane. Conditions of approval 1.c and 12 for the Sand. Hill Road Extension and Related Roadway Improvements project, as adopted by condition of approval 2.h for this project, provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, as applicable, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its 13 970702 lac 00315al fair share based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Middlefield Avenue/Willow Road: Mitigation measure 4.4-7(e) identifies a number of improvements which would be necessary to mitigate cumulative traffic impacts at this intersection, including the following: Add a second southbound left turning lane. Restripe eastbound approach. Modify signal phasing, including a leading left turn phase in the signal phasing for the north and south directions. The timing of these improvements will be determined by the City of Menlo Park, through periodic monitoring and/or through subsequent environmental impact analysis and documentation. Condition 2.i partially implements this mitigation measure by requiring that the applicant shall either make signal timing improvements sufficient to return traffic levels of service at this intersection to level of service D, or contribute its fair share of the costs to construct the recommended intersection improvements. This obligation would not be triggered until current level of service falls to E or worse. Sand Hill Road/Santa Cruz Avenue and Junipero Serra Blvd./Alpine Road: Mitigation measure 4.4-7(h) provides that the applicant shall conduct an operational analysis of the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections to identify the appropriate combination of roadway and traffic signal improvements necessary to improve operation to LOS D during peak hours, if feasible. The EIR also recommends that the following mitigation measures be implemented to mitigate cumulative traffic impacts at specified intersections within the City of Menlo Park, but does not provide for direct participation by the applicant in implementation of these mitigation measures. El Camino Real/Ravenswood Avenue: Mitigation measure 4.4-7(f) recommends that the following improvements to the El Camino Real/Ravenswood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: Widen northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. 14 970702 lac 0031537 Widen westbound approach -to add exclusive right turn lane. El Camino Real/Valparaiso Avenue/glenwood Avenue: Mitigation measure 4.4-7(g) recommends that the following improvements to the El Camino Real/Valparaiso Avenue/Glenwood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: Restripe northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. Widen westbound approach to add exclusive right turn lane. Final design shall include provisions for bicycle traffic. In addition, the EIR recommends that signal phasing at this intersection be modified to include split phasing in the east/west direction and a leading left turn phase in the north/south direction. In addition to these specific mitigation measures recommended in the EIR, the final conditions of approval for the Stanford West Apartments project include a number of additional conditions which are intended to reduce individual automobile trips to and from the project site, and thereby potentially further reduce the project's impacts on area intersections. These conditions include the following: Condition 7.g requires the construction of a bicycle and pedestrian connecting pathway between the Stanford West Apartments and neighboring Oak Creek Apartments, if approval for this connecting pathway is obtained from the ground lessee of the Oak Creek Apartments property. Condition 14.A requires the applicant to provide for on -site child care. The provisions for a child care facility are more fully described in the Development Agreement. Condition 62 requires the applicant to provide an on -site convenience retail facility to enable residents to make small purchases of convenience food and household items without generating off -site vehicle trips. Changes to the tiered priority system for the project have been included in the Development Agreement for the project. These changes will result in increased priority for Stanford employees who are likely to be able to travel to and from work by foot, bicycle or public transit. 15 970702 lac 0031587 The Council finds that these adopted changes and mitigation _ measures, if implemented, will lessen the project's impacts on traffic at the four significantly affected intersections to a less than significant level, and will also substantially lessen the impact of the project's contribution to cumulative traffic at other intersections significantly affected by the Sand Hill Corridor projects collectively. Mitigation measures 4.4 -7(a) -(e), as modified by the conditions of approval, require the applicant to pay all or a fair share of the costs of physical improvements necessary to enable each of the affected intersections to serve anticipated cumulative traffic demands at acceptable levels of service. Mitigation measure 4.4-7(h) also provides for - identification of appropriate additional intersection improvements should the City of Menlo Park elect to achieve a higher level of service at the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections. Conditions of approval 7.g, I4.A and 62 require additional changes to the project which will potentially eliminate some vehicle trips to and from the project site by providing- on -site child care and convenience shopping facilities, thus eliminating the need for some vehicle trips, and by encouraging use of bicycles or walking for visits between residents of the Oak Creek Apartments and Stanford West Apartments. The Council recognizes that final authority to approve and 'implement the identified mitigation measures at three of the four intersections significantly affected by the project is vested in public agencies other than the City, specifically the County of Santa Clara (mitigation measure 4:4-7(a), Arboretum Road/Galvez Street); the City of Menlo Park (mitigation measures 4.4-7(c), Sand Hill Road/Santa Cruz Avenue and 4.4-7(e), Middlefield Avenue/Willow Road); and the County of San Mateo (mitigation measure 4.4-7(c), Sand Hill Road/Santa Cruz Avenue)-- Responsibility and authority for implementing the recommended mitigation measures at the additional intersections cumulatively impacted by the project is also vested in other public agencies, specifically the City of Menlo Park (mitigation measures 4.4-7(f), El Camino Real/Ravenswood Avenue, and 4.4-7(g), El Camino Real/Valparaiso Avenue/Glenwood Avenue) and 4.4-7(d), Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue) . The Council finds that the identified mitigation - measures can and should be approved and implemented by these agencies. However, the Council also recognizes that in the event that one or more of the listed mitigation measures are not approved and implemented by the appropriate responsible agency, the project will cause significant adverse impacts on the Arboretum Road/Galvez Street, Middlefield Ave./Willow Road and/or Sand Hill Road/Santa Cruz Avenue intersections, and may contribute to significant impacts at other intersections cumulatively affected by the Sand Hill Corridor projects. Because it cannot presently be determined if or when the appropriate mitigation measures will be implemented by the respective responsible agencies, these impacts are ccnsidered by the Council to be potentially significant. 16 970702 Lc 0031587 4.4-8 Construction activities could lead to both temporary disruption of transportation system operation, as well as to permanent damage to elements of the system such as pavement and bridges. Mitigation measure 4.4-8(a) requires the applicant to provide adequate off-street parking for all construction -related vehicles throughout the construction period. If adequate parking cannot be provided on the construction sites, a satellite parking area shall be designated, and a shuttle bus shall be operated to transfer construction workers to the job sites. Mitigation measure 4.4-8(b) provides that construction activities related to the project are prohibited from substantially limiting pedestrian access (e.g, by blocking pedestrian routes), without prior approval from the City of Palo Alto and/or Caltrans. Any approval shall require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4-4.8(c) provides that the applicant shall be prohibited from limiting bicycle access (e.g. by blocking or restricting existing routes) while constructing the project, without prior approval from the City of Palo Alto and/or Caltrans or the City of Menlo Park (depending upon the jurisdiction of the requested action). Any approval will require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(d) provides that -the applicant shall be required to prohibit or limit the number of construction material deliveries from 7 a.m. to 9 a.m., and from 4 p.m. to 6 p.m. on weekdays. Mitigation measure 4.4-8(e) provides that the applicant shall be required to prohibit or limit the number of construction employees arriving or departing the site from the hours of 4:30 p.m. to 6 p.m. Mitigation measure 4.4-8(f) requires that all construction -related equipment and materials shall be delivered and removed on truck routes designated by the cities of Palo Alto and Menlo Park. Heavy construction vehicles shall be prohibited from accessing the sites from other routes. Mitigation measure 4.4-8(g) requires the applicant to repair any structural damage to public roadways caused by construction equipment or vehicles, returning any damaged sections to original structural condition. The effectiveness of this measure shall be guaranteed by requiring surveys of road conditions before and after construction. Mitigation measure 4.4-8(h) prohibits the applicant from limiting access to public transit (e.g. by relocating or restricting access to bus stops or transfer facilities), and from 17 970702 lac 0031587 limiting movement of public transit vehicles, without prior approval from the Santa Clara Transit Agency or other appropriate jurisdiction. Any approval will require submittal of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(i) provides that in lieu of mitigation measures 4.4-8(a) through (h), the project applicant may prepare a detailed construction impact mitigation plan for approval by the City's Chief Transportation Official and City of Menlo Park Transportation Manager prior to commencing any construction activities with potential transportation impacts in their respective jurisdictions. The plan must address all aspects of construction traffic management necessary to eliminate or reduce transportation impacts to acceptable levels. The Council finds that adoption of these measures will lessen the project's potential construction phase traffic and transportation impacts to a less than significant level. These measures provide for comprehensive planning for construction traffic to avoid conflicts with other transportation needs and establish standards and criteria which will ensure that significant adverse impacts are avoided. 4..5 AIR QUALITY 4.5-1 The PM,a generated during the construction of the proposed projects could be harmful to nearby pollutant -sensitive land uses. Mitigation measure 4.5-1 requires the applicant to implement a construction phase program which includes the following measures to reduce generation of particulate matter on the project site during construction: Water all active construction areas at least twice a day, or as needed to prevent visible dust plumes from blowing off -site. Use tarpaulins or other effective covers for on -site storage piles and for haul trucks on public.. streets. Pave, apply water three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas during construction. Sweep all paved access routes, parking areas, and staging areas daily (preferably with water sweepers). Sweep streets daily (preferably with water sweepers) if visible amounts of soil material is carried onto public streets. If the working area of any construction site exceeds four acres at any one time, implement the following additional measures: 18 9707702 lac 0031587 Apply (non-toxic) soil stabilizers to inactive construction areas. Enclose, cover, water twice daily, or apply (non-toxic) soil binders to exposed stockpiles. Limit construction site vehicle speed to 15 mph on unpaved areas. Replant vegetation in disturbed areas as quickly as possible. If the working area of any construction site is located near any sensitive receptors, implement the following measures in addition to those listed above: Suspend excavation and grading activity when winds exceed 25 mph. The last mitigation would be applicable to the Stanford West Apartments site where it approaches the Children's Health Council. The Council finds that adoption of this mitigation measure will lessen the identified impact to a less than significant level. Implementation of twice daily watering has been shown to reduce' construction site PMw emissions by at least 50 percent. This practice, in conjunction with the other listed measures, will reduce PM1c emissions during construction to less than the BAAQMD threshold of significance for all anticipated construction activity. 4.5-2 ROG, NOx, and PM emissions generated by motor vehicles and residential stationary sources associated with the proposed projects would exceed the 80 lbs/day threshold and could hinder regional and local attainment of State ozone and PMyo standards. The EIR concludes that air pollution emissions from the project -- almost entirely from related vehicle traffic -- would be approximately 55 lbs/day for reactive organic compounds (ROG), 65 lbs/day for nitrogen oxides (NOx) and 51 lbs/day of PMM0 particulates, all below the threshold of significance recognized by the BAAQMD and utilized in the EIR. Due to continuing changes in automotive technology, it is further expected that emissions would drop to 26 lbs/day of ROG and 49 lbs/day of NOx and remain at 51 lbs/day of PMT0 by the year 2010. The project therefore will not individually have a significant adverse effect on air quality. The EIR also concluded, however, that the project would contribute to significant total air quality impacts from the Sand Hill Road Corridor projects as a whole. The conditions of approval of the project, however, do include measures intended to reduce overall numbers of vehicle trips from the project and resulting air pollution emissions. 19 970102 lac 00315E7 Mitigation measure 4.5-2 (a) requires the City to implement mitigation measure 4.4-2(a), which provides that final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed to ensure the circulation system will function as a part of regional or inter -city bicycle and pedestrian connections, thereby promoting increased use of bicycles or pedestrian travel by area residents. Condition 7.g requires the construction of a bicycle and" pedestrian connecting pathway between the Stanford West Apartments and neighboring Oak Creek Apartments, if approval for this 'connecting pathway is obtained from the ground lessee of the Oak Creek Apartments property. Condition 14.A, as more fully described in the Development Agreement, requires the applicant to provide for on -site child care, which will eliminate the need for project residents to drive to off -site child care. Condition 62 requires the applicant to provide a small on -site convenience retail facility, which will enable residents to make purchases of convenience food and household items without generating off -site vehicle trips. Changes to the tiered priority system for the project have been included in the Development Agreement for the project. These changes will result in increased priority for Stanford employees who are likely to be able to travel to and from work by foot, bicycle or public transit_ The Council finds that these measures will lessen project related air pollution impacts somewhat, but will not reduce the cumulative impact of the Sand Hill Corridor Projects to less than significant levels. The cumulative air quality impacts of the Sand Hill Corridor Projects will therefore be significant. 4.5-4 Cumulative daily traffic along major roadways in the project and study areas would emit more NOX, and PN6 with the implementation of the Sand Hill Road Projects, but emissions of ROG would decrease. The SIR did not identify any mitigation measures for this area -wide cumulative impact. The Council has adopted various project conditions and mitigation measures, including mitigation measure 4.5-2(a) and Conditions 7.g, 14.A, as further described in the Development Agreement, and 62, as well as the tiered priority rental system described in the Development Agreement, to reduce traffic from the Stanford West Apartments project. However, cumulative traffic -related air pollution emissions are regulated primarily through measures beyond the City's jurisdiction or control. Individual vehicle emissions and automotive fuels are subject to regulation only by state or federal government. Regional traffic levels are also heavily influenced by past and future planning and land use decisions of other jurisdictions aver which the City has no control. The Council therefore finds that no 20 970702 lac 0031587 • additional feasible mitigation measures are presently available to the City to substantially lessen cumulative air quality impacts due to increases in regional traffic and that these impacts must therefore be considered significant. 4,6 NOISE 4.6-1 The noise generated during the construction of the proposed projects could be disruptive to nearby noise -sensitive land uses. Mitigation measure 4.6-1(a) provides that construction activities will be limited to the hours of 8:00 a.m. to 8:00 p.m. Monday through Friday, and if weekend work is necessary, to the hours of 9:00 a.m. to 8:00 p.m. on Saturday, and to the hours of 10:00 a.m. to 6:00 p.m. on Sunday. Mitigation measure 4.6-1(b) provides that construction equipment shall be outfitted and maintained with noise reduction devices (i.e., mufflers, enclosures for stationary equipment, etc.) to obtain at least an average 10 dHA reduction shown feasible in Table 4.6-5. Mitigation measure 4.6-1(c) - provides that stationary noise sources (e.g., compressors, concrete mixers, etc.) shall be located on portions of the sites furthest away from residential and other noise -sensitive areas, and that acoustic shielding shall be used with such equipment. The Council finds that adoption of these measures will substantially lessen construction phase noise impacts on surrounding residents, but will not reduce these impacts to a less than significant level. The adopted mitigation measures will directly reduce noise generated by construction activities on -site and will eliminate construction noise impacts during normal sleeping hours. However, construction noise impacts will remain significant due to the levels of noise unavoidably generated by large scale construction activity and heavy equipment. 4.6-3 Traffic generated by the proposed projects and other cumulative developments and the traffic accommodated by the proposed roadway improvements would impact existing and proposed residential and other sensitive land uses adjacent to roadways in the project and study areas. Mitigation measure 4.6-3(a) requires that project residential units. facing Sand Hill Road contain sufficient acoustic insulation to meet State Title 24 indoor noise standards. The Council finds that this mitigation measure will reduce any potential significant noise impacts on project residents to a less than significant level by requiring noise protection to be built into residential units to reduce interior noise levels to acceptable levels. 21 970702 lac 0031587 The EIR also concluded that although the project would not cause significant noise impacts, traffic from the project would contribute for cumulative noise impacts on some residences along Sand Hill Road. The conditions of approval for the project therefore incorporate the following mitigation measures to assist in mitigating potential cumulative traffic -related noise impacts. Mitigation measure 4.6-3(b) requires the applicant to construct a landscaped buffer strip with at least a 3 -foot -high berm along Sand Hill Road between Stanford Avenue and Oak Avenue in conjunction with implementation of the Sand Hill Road widening and realignment between Santa Cruz and Oak Avenues. Mitigation measure 4.6-3(c) requires the applicant to construct a soundwall 6 feet high or higher between Santa Cruz Avenue and Stanford Avenue in conjunction with implementation of the Sand Hill Road widening to reduce noise from traffic increases at the nearby intersection. Mitigation measure 4.6-3(d), as modified by Condition 2.e of the project conditions of approval, requires the applicant to monitor noise increases in residences in the designated areas along Sand Hill Road where the Sand Hill Road Corridor projects may be responsible for more than 50% of potential increases in traffic -related noise. If noise increases are detected, the applicant shall be responsible for the costs of measures such as additional insulation, double -glazed windows, or individual soundwalls as determined necessary by acoustic study to return interior noise levels in these residences to pre -project levels or 45 dBa. Residents may also contribute any further funds necessary to further reduce interior noise levels to acceptable levels. The Council finds that these mitigation measures, if implemented, will substantially lessen significant cumulative traffic -related noise impacts along the Sand Hill Road corridor although these measures will not necessarily reduce cumulative noise impacts to a less than significant level for every residence affected by the project. Mitigation measure 4.6-3(d) provides for a fair share contribution by the applicant to the costs of physically upgrading affected residences with noise mitigation measures. Mitigation measures 4.6-3(b) and 4.6-3(c) provide for construction of physical barriers to reduce noise to acceptable levels at protected residences. The adopted mitigation measure 4.6-3(d) will impose responsibility for necessary monitoring of actual noise increases on the applicant and also imposes responsibility on the applicant to pay a share of actual mitigation costs in proportion to the applicant's responsibility for these impacts where the Sand Hill Corridor projects are the predominant cause of cumulative traffic -related noise impacts. The Council does not believe that the applicant can or equitably should be held responsible for more than a fair share of the costs of mitigating these potential cumulative noise impacts. Revisions made by the City to mitigation measure 4.6-3(d) are intended to strengthen the measure by fixing responsibility for noise monitoring on the applicant, and to also amend the measure to provide that the 22 970702 lac 0031587 • applicant Shall be financially responsible only for a fair share of the costs of implementing the mitigation measure. The Council recognizes that mitigation measure 4.6-3(d), as adopted, will not result in lessening of cumulative noise impacts at locations at which less than 50% of the cumulative traffic -related noise increase is attributable to the Sand Hill Corridor projects. The Council also recognizes that since implementation of mitigation measure 4.6-3(d) also requires the cooperation of affected homeowners, the physical improvements necessary to reduce noise levels at some affected residences to acceptable levels may not be constructed by choice of the owner. The Council therefore recognizes that notwithstanding adoption of the identified mitigation measures, cumulative traffic -related noise impacts may remain significant for some residences affected by the projects. With respect to mitigation measures 4.6-3(b) and 4.6-3(c), which will mitigate noise impacts on certain residences in Menlo Park, the Council further recognizes that although the conditions of approval require the applicant to accept responsibility for implementation of these mitigation measures, approval for implementation of these measures must be obtained from the City of Menlo Park. The Council finds that implementation of these mitigation measures can and should be approved by the City of Menlo Park. The Council also recognizes, however, that in the event that approval for implementation of these measures is not obtained from Menlo Park, affected residences in Menlo Park would experience significant cumulative traffic -related noise impacts due to increased cumulative traffic on Sand Hill Road. 4.7 BIOLOGICAL RESOURCES 4.7-1 Implementation of the proposed projects would result in loss of trees and associated wildlife habitat. Mitigation measure 4.7-1(a) requires that native trees removed for the projects shall be replaced at a ratio of 3:1 on a per acre basis with specimens of the same species obtained from locally collected stock, and provides for additional replanting if survival rates fall below 80 percent. - Mitigation measure 4.7-1(b) requires that non-native landscape trees removed for the projects be replaced on a two -to -one basis. Mitigation measure 4.7-1(c) provides that the City shall contract with an independent arborist to (a) review construction plans to provide for maximum retention of trees and necessary additional tree protection measures; b) monitor project construction; and c) recommend changes in the tree removal plan as necessary during construction. Mitigation measure 4.7-1(e) requires that all trees adjacent to project construction areas which are not removed will be avoided and protected according to specified procedures incorporated into all construction and/or demolition contracts. 23 970702 lac 0031587 The Council finds that adoption of these measures will lessen the project's long term impacts on trees and related wildlife habitat to less than significant levels. The adopted measures will also substantially lessen but will not avoid significant adverse short term and intermediate term impacts. The adopted measures provide for protection of as many trees as possible during project construction and replacement of all trees removed as a result of the project at a 2-1 to 3-1, ratio with additional measures to ensure the success of replanting. This mitigation program will therefore eventually result in replacement habitat of equal or greater value. However, because it will take a number of years before replacement trees reach a level of maturity to those being removed and provide equivalent habitat value, there will bea significant short-term and intermediate term decline in quality of trees and related habitat value at the project site. 4.7-2 Construction of the proposed projects would result in tree removals that could directly destroy nests, eggs and immature birds, and would remove future nesting habitat for birds, including sensitive species such as raptors and migrating songbirds. Mitigation measure 4.7-2(a) provides that in order to avoid the nesting season of raptors and sensitive songbirds, tree. removals shall not take place between February 15 and June 30, unless otherwise determined by the California Department of Fish and Game (CDFG) on a case -by -case basis. Mitigation measure 4.7-2(b) provides that if tree removal between January 1 and February 15 is required, a pre -construction survey shall be conducted to identify the presence, or lack thereof, of nests of raptors. If nests are identified, CDFG shall be contacted and appropriate protocols for nest relocation shall be implemented. If relocation of occupied, viable nests is not feasible, construction shall be delayed and the tree left undisturbed until completion of nesting activity. Mitigation measure 4.7-2(c) requires implementation of mitigation measures 4.7 -1(a) -(f) and 4.7 -4(a) -(c) (tree replacement .and riparian habitat replacement), discussed above and below. The Council finds that adoption of these measures will lessen the project's impacts on nesting birds to a less than significant level. These measures will avoid any direct destruction of nests and provide for eventual replacement or enhancement of all nesting habitat lost. While there will be a short term loss of nesting habitat for all bird species and short and intermediate term loss of nesting habitat for raptors, there are sufficient alternate nesting sites in the area that this impact will not have any significant adverse effect on overall nesting opportunities or on bird populations. 4.7-3 Loss of non-native grasslands near San Francisquito Creek Mitigation measure 4.7-3(a) provides that grassland habitat shall be preserved within the area between San Francisquito Creek 24 970702 lac 0031387 • and the Stanford West Apartments. This area shall be enhanced by protection from discing, and by replanting with native grasses and wildflowers and monitored for at least five years to ensure success. Mitigation measure 4.7-3(b) requires that remaining grassland habitat be enhanced by seeding with a mix of California native grasses and forbs, and/or planting of plugs of native grasses before winter rainfall in the year of grassland removal. Mitigation measure 4.7-3(c) requires that all replacement grassland shall be planted on -site. Mitigation measure 4.7-3(d) requires that all replacement grassland shall be monitored for a minimum of two years to ensure at least 50 percent survival. If irrigation or fertilizers are used, all replacement grasses shall be "weaned" of any supplemental. water and fertilizer by the third year. Mitigation measure 4.7-3(e) requires that a yearly maintenance and monitoring report shall. be provided to the City detailing compliance with the replacement planting success criteria. If the. success criteria are not met, the City shall require the project applicant to implement remedial actions that will result in a minimum 50 percent survival after five years of the last date of planting. Mitigation measure 4.7-3(f) provides that mowing for fire control shall be performed around the perimeter of any grassland areas, leaving as much of the internal area intact as allowable to local fire authorities, and leaving the mowed area no higher than 18 inches. Mitigation measure 4.7-3(g) provides that the City may require a performance bond or other security to ensure any necessary replanting of grasslands if determined necessary. This mitigation measure is. implemented and modified by Condition 2 of the project conditions of approval. Mitigation measure 4.7-3(h) requires the applicant to prohibit future use of retained grassland area for any construction -related activities. The Council finds that adoption of these measures will lessen the project's impacts on grassland habitats to a less than significant level. The mitigation measures provide for preservation and enhancement of a substantial area of natural grasslands on the site. The FIR indicates that native revegetation can increase general habitat values and the carrying capacity for wildlife using this area. The cessation of discing can increase the burrowing rodent population for foraging raptors. Consultation with CDFG indicates that enhancement of the remaining grassland can mitigate the overall impact of the project on grasslands to a less than significant level. 25 970702 lac 00315W7 4.7-8 Ongoing operation of the proposed projects could adversely affect aquatic life, including sensitive animal species, in San Francisquito Creek, by increasing runoff and non -point source urban pollutant loads. Mitigation measure 4.7-8(a) requires implementation of mitigation measures 4.9 -1(a) -(c), discussed below. Mitigation measure 4.7-8(b) requires implementation of mitigation measures 4.9-4(a) and (b), discussed below. The Council finds that adoption of these measures will lessen the project's potential impacts on aquatic life in San Francisquito Creek to a less than significant level. The mitigation measures provide for implementation of construction phase and post -construction storm water runoff management plans which will utilize recognized best. management practices to minimize siltation and runoff of contaminants from the project site. Residual silt and contaminant runoff reaching San Francisquito Creek is not expected to constitute a sufficient addition to loads from existing development in the watershed to result in any measurable further deterioration of water quality conditions. 4.7-9 Operation of the proposed projects would increase human access resulting in direct impacts to sensitive animal species and disturbance and trampling damage to sensitive riparian habitat adjacent to San Francisquito Creek and to the Creek channel. Mitigation measure 4.7-9(a) requires that existing trails providing access to the riparian habitats along San Francisquito Creek be obliterated by dense barrier plantings of native riparian shrubs. A new trail will be designed for the length of the San Francisquito riparian corridor in the project area, located outside of riparian habitats and the drip lines of existing trees. Appropriate measures will be utilized to encourage exclusive use of this trail. Educational interpretive signs and displays shall be posted along this trail. View points shall be established in areas adjacent to the Creek where their siting will cause minimal damage to existing riparian vegetation. Direct public access to the Creek bank and channel shall not be permitted except over existing crossings and for access to these carefully sited view points. The Council finds that adoption of this mitigation measure will lessen the potential impacts of increased human intrusion of the San Francisquito Creek riparian area to a less than significant level_. The adopted measure provides for substantial preventive action to minimize future human intrusion and resulting impacts to the riparian zone, and for restoration of existing damage, thus potentially resulting in a net beneficial impact to the riparian corridor. _ 26 970702 lac 0031307 4.7-10 Implementation of the proposed projects, in conjunction with other proposed projects in the area would result in incremental loss of trees and associated wildlife habitat. Mitigation measure 4.7-10(a) requires implementation of mitigation measures 4.7-1(a, b, c, and e), discussed above, for all Sand Hill Corridor projects. Mitigation measure 4.7-10(c) recommends that all planning jurisdictions in the project area implement their respective tree protection and preservation ordinances. For those jurisdictions without such an ordinance, measures similar to those presented in mitigation measure 4.7-1 should be implemented on- a project -by -project basis. The Council has adopted the recommended mitigation measures for the Stanford West Apartments project and other approved Sand Hill Corridor projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the cumulative loss of trees and associated wildlife habitat to a less than significant level. Adoption and implementation of these measures in conjunction with the Stanford West -Senior Housing and Sand Hill Road Extension and Related Roadway Improvements projects will also reduce the combined cumulative impact of the projects to,a less than significant level. These measures generally provide for full replacement of trees lost due to implementation of the project, thus eliminating any significant cumulative impact. Adoption of equivalent mitigation measures for future development projects reviewed by "the City is beyond the scope of approvals granted for the project. The Council finds, however, that City decisionmakers can and should adopt such measures in conjunction with any future projects which may result in cumulative loss of trees and associated wildlife habitat within the City. With respect to future implementation of .the recommended measures by other jurisdictions in the area, the Council finds that implementation is within the jurisdiction and responsibility of the identified other agencies and that such measures can and should be adopted by such agencies. However, because the nature and extent of potential cumulative impacts from future development in the area are presently speculative and unknown, and the extent to which the recommended mitigation measures will be implemented by all responsible jurisdictions is also presently unknown and is beyond the control of the City, the Council cannot determine at this time the extent to which the recommended measures will lessen or avoid the potential cumulative impact, and therefore finds that the cumulative impact remains potentially significant. 27 970702 lac 0031587 ! - ! 4.7-11 Construction of the proposed projects, in conjunction with other projects in the project area, would cumulatively result in tree removals that could directly destroy nests, eggs and immature birds, and would remove future nesting habitat for birds, including sensitive species such as raptors and migrating songbirds. Mitigation measure 4.7-11(a) requires implementation of mitigation measures 4.7 -2(a -c), discussed above, for the Sand Hill Corridor development projects. Mitigation measure 4.7-11(b) recommends that all planning jurisdictions in the project area implement measures similar to those presented in mitigation measure 4.7-2 on a project -by -project basis. The conditions of approval for the Stanford West Apartments project incorporate the applicable project -specific mitigation measures recommended in mitigation measure 4.7-11(a). The Council has also adopted the recommended project -specific mitigation measures as conditions of approval for the Stanford West Senior Housing and Sand Hill Road Extension and Related Roadway Improvements projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level. Adoption of these mitigation measures in conjunction with the approved projects will also reduce the combined cumulative impact of the projects to a less than significant level. These measures generally provide for avoidance of tree -cutting which may directly impact nesting activities and provide for full replacement of trees lost due to implementation of the project, thus eliminating any significant cumulative impact. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can -and should be adopted in conjunction with any future projects approved by the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of the potential cumulative impact from future projects is presently entirely speculative and unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative visual impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 28 970702 lac 0031587 • • 4.7-12 The proposed projects, in conjunction with other proposed projects in or adjacent to the San Francisquito Creek riparian corridor, would result in the loss of non-native grasslands which, due to contiguousness with riparian habitat, provide increased habitat diversity and foraging habitat for certain wildlife species, including raptors. Mitigation measure 4.7-12(a) requires implementation of mitigation measures 4.7 -3(a -h), discussed above. Mitigation measure 4.7-12(b) recommends that further development of open grassland areas adjacent to San Francisquito Creek or its tributaries (primarily in the foothills southwest of Junipero Serra Road) not be approved without provisions to implement mitigation measures similar to those of Mitigation Measure 4.7 -3(a) -(h), in consultation with CDFG. The Council has adopted the recommended mitigation measures for the project and other approved Sand Hill Corridor projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to potential cumulative losses of trees and nesting habitat to a less than significant level. With respect to future projects within the City's jurisdiction which may contribute to cumulative loss of cultural resources, the City will consider implementation of the recommended measures at the time future development projects are proposed. With respect to future implementation of the recommended measures by other jurisdictions in the area, the Council finds that implementation is within the jurisdiction and responsibility of the identified other agencies and that such measures can and should be adopted by such agencies. However, because the nature and extent of potential cumulative impacts from future development in the region are presently speculative and unknown, and the extent to which the recommended mitigation measures will be adopted by all responsible jurisdictions is also presently unknown and is beyond the control of the City, the Council cannot determine at this time the extent to which the recommended measures will lessen or avoid this potential cumulative impact, and therefore finds that the cumulative impact remains potentially significant and unavoidable. 4.7-15 Ongoing operation of the proposed projects, in conjunction with similar projects within the same watershed, could cause cumulative adverse affects on aquatic life, including sensitive animal species, in San Francisquito Creek, by increasing runoff and non -point source urban pollutant loads. Mitigation measure 4.7-15 recommends implementation of the mitigation measures prescribed in mitigation measures 4.9 -7(a) -(c) for all future projects in the San Francisquito Creek watershed. The conditions of approval for the Stanford West Apartments project incorporate each of the applicable recommended project -specific mitigation measures. The Council has also adopted 29 970702fsc0031587 the recommended project -specific mitigation measures as conditions of approval for the other Sand Hill Corridor projects approved concurrently with the project. The Council finds that adoption of these recommended project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level. Adoption and implementation of these mitigation measures in conjunction with the other Sand Hill Corridor projects will also reduce the combined cumulative impact of these projects to a less than significant level. The adopted project -specific measures generally provide for preparation and compliance with detailed Storm Water Pollutant Prevention Plans which will include specific measures to prevent excessive sediment or pollution runoff which might result in significant adverse effects on aquatic life or habitat values in San Francisquito Creek. Adoption of the recommended mitigation measures or equivalent measures for future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects approved by the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of the potential cumulative impact from future projects is presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative impact resulting from.increased runoff of sediment and pollutants into San Francisquito Creek. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.7-16 Operation of the proposed projects, in conjunction with similar projects in or adjacent to.the riparian corridor of San Francisquito Creek or its tributaries, would increase human access, cumulatively resulting in direct impacts to sensitive animal species and disturbance and trampling damage to sensitive riparian habitat. Mitigation measure 4.7-16(a) requires implementation of mitigation measures 4.7-9(a) and (b), discussed above for the Stanford West Apartments and Stanford West Senior Housing projects. Mitigation measure 4.7-16(b) recommends that all planning jurisdictions in the project area implement measures similar to those presented in mitigation measure 4.7-9 on a project -by -project basis. 30 970702 lac 0031587 i The Council has adopted each of the project -specific mitigation measures referenced in mitigation measures 4.7-16(a) and 4.7-16(b), in the conditions of approval for the Stanford West Apartments project and Stanford West Senior Housing project. The Council finds that adoption of the recommended project -specific measures will lessen the projects' contribution to potential cumulative impact on the San Francisquito Creek riparian corridor to a less than significant level. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and. should be adopted in conjunction with any future projects within the City located near riparian habitat areas. With respect to future development projects located outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative impacts from future development are presently entirely speculative and unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative effects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the Council. 4.8 GEOLOGY. SOILS AND SEISMICITY 4.8-1 Expansive or weak soils could damage foundations by providing inadequate support. Mitigation measure 4.8-1(a) requires that site specific soil suitability analysis be conducted and soil stabilization procedures and foundation design criteria be adopted in accordance with engineering criteria where the existence of expansive and compressible soil conditions is known or suspected. Mitigation measure 4.8-1(b) requires participation by the project's registered soil engineer as deemed necessary to oversee, verify, and report on soil engineering procedures and results. The EIR concludes that this impact is potentially, but not necessarily, significant, based on actual conditions encountered at the site. The Council finds that adoption of these mitigation measures will lessen impacts related to potentially expansive or weak soils to a less than significant level. These measures provide for implementation of standard engineering procedures and criteria which will ensure construction of safe buildings and foundations. 31 970702 lac 0031587 • • 4.8-2 "The Stanford Sand Rill Road Corridor Projects area is subject to very strong seismically induced groundshaking which could threaten life and damage property. Mitigation measure 4.8-2(a) requires documented site -specific seismic -restraint criteria to be incorporated in the design of foundations and structures of project structures. The criteria must meet the minimum seismic -resistant design standards of CUBC Seismic Zone 4. Additional seismic -resistant earthwcrk and construction design criteria will be incorporated in the project where recommended by qualified experts. Roads, foundations and underground utilities in fill or alluvium shall be designed to accommodate settlement or compaction produced by seismic forces. Mitigation measure 4.8-2(b) requires on -site participation by the project's registered geological or geotechnical engineering consultant, as deemed appropriate, to oversee, verify,- and report on seismic -restraint procedures and results. Mitigation measure 4.8-2(c) requires that an engineering geologist be contracted for third party review of all geologic, soils and engineering reports prepared for the proposed projects. The Council finds that adoption of these measures will lessen the impact of exposure to seismic events to a less than significant level. These measures implement standard engineering procedures and criteria for preventing major building failures and resulting injury or loss of life from any seismic event reasonably anticipated to occur in the project. area - 4.8 -4 Implementation of any combination of the projects, in conjunction with cumulative development within San Mateo and Santa Clara counties and the cities of Palo Alto and Menlo Park, would increase the number of people and structures subject to strong seismic groundshaking and the subsequent risk of injury, loss of life and property damage. Mitigation measure 4.8-4(a) recommends that documented site -specific seismic -restraint criteria to be incorporated in the design of foundations and structures of all future development in the project area, including (1) minimum seismic -resistant design standards shall conform to the CUBC Seismic Zone 4 Standards; (2) additional seismic -resistant earthwork and construction design criteria shall be incorporated as necessary, based on the site -specific engineering recommendations; (3) site preparation shall be supervised by geological or geotechnical consultants; (4) "as built" maps and a report shall be filed with the City, showing details of the site geology, the location and type of seismic -restraint facilities, and documenting satisfactory seismic performance for buildings, roads, foundations and underground utilities. Mitigation measure 4.8-4(b) recommends requiring on -site oversight, verification and reporting by registered geological or 32 970702 lac 0031587 geotechnical engineering consultants where. deemed appropriate by the City's Chief Building Official. The conditions of approval for the Stanford West Apartments project and for each of the other approved Sand Hill Corridor projects incorporate measures equivalent to the project -specific mitigation measures recommended in mitigation measure 4.8-4(a). The Council finds that adoption of these project -specific measures will lessen the project's contribution to the identified cumulative impact to a less than significant level, and will also lessen the combined cumulative impact of the Sand Hill Corridor projects to a less than significant level. The adopted project -specific measures generally provide for incorporation of adequate seismic safety measures into all new construction as provided by mitigation measures 4.8 -2(a) -(c). Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects approved by the City. With respect to cumulative impacts from future development outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that these agencies can and should implement such measures. Because the recommended mitigation measures rely in part upon compliance with existing seismic safety practices and standards, it is expected that other jurisdictions will implement the measures to a. large extent. However, because the extent of the potential cumulative impact from future projects is presently unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures beyond current minimum standards is uncertain, the Council cannot fully determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen the potential cumulative impact associated with increased development in the seismically sensitive region around the projects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.9 HYDROLOGY AND WATER QUALITY 4.9-1 Grading, excavation and construction activities could result in increased deposition of sediment and/or discharge of pollutants in the storm drainage system and San Francisquito Creek and adversely affect water quality. Mitigation measure 4.9-1(a) requires the applicant to prepare, retain and implement a SWPPP which describes the site, erosion and sediment controls, means of material storage and waste disposal, implementation of approved local plans, post -construction control measures and maintenance responsibilities, and non -storm water management controls. The plan shall implement appropriate Best Management Practices ("BMPs") identified in the EIR. 33 970702 lac 0031587 . • Mitigation measure 4.9-1(b) requires that the SWPPP shall be prepared by a qualified professional and approved by the City's Director of Public Works prior to issuance of a building permit. The SWPPP shall be implemented and inspected as part of the approval process for the grading plans for each project. Mitigation measure 4.9-1(c) requires that all construction contracts include the City's construction contract Pollution Prevention Language as part of the project specifications. The Council finds that adoption of these measures will lessen the project's potential sedimentation and contaminant impacts on San Francisquito Creek to a less than significant level. The adopted mitigation measures implement regulatory requirements and practices demonstrated to prevent excessive or damaging runoff of sediments and pollutants from development sites. Residual runoff of sediments and contaminants from construction areas, if any, will not occur in sufficient quantities to significantly -degrade existing water quality. 4.9-4 Increased impervious surface and landscaping associated with development of the Proposed Projects could increase urban contaminants in surface runoff potentially reducing water quality in San Francisquito Creek. Mitigation measure 4.9-4(a) requires implementation of mitigation measures 4.9-1(a) through (c) for all approved Sand Hill Corridor projects. Mitigation measure 4.9-4(b) requires that the Storm Water Pollution Prevention Plan (SWPPP). shall include in the final project design appropriate BMPs selected by the City, consisting either of detailed measures specified in the EIR or equivalent measures. The Council finds that adoption of these measures will lessen the project's potential impacts on San Francisquito Creek to a less than significant level. The adopted mitigation measures require implementation of design features and operational practices which will reduce contamination of exposed surfaces at the project site and trap or otherwise minimize runoff of such contaminants from the site. Residual contaminant runoff reaching San Francisquito Creek is not expected to constitute a sufficient addition to loads from existing development in the watershed to result in any measurable further deterioration of water quality. 4.9-5 Project construction activities in coMbination with other construction projects in the Watershed could cumulatively increase sediment and other construction -related pollutants in San Francisquito Creek and adversely affect water quality. Mitigation measure 4.9-5(a) recommends that all area jurisdictions ensure that project applicants include BMPs in construction contracts implementing the requirements of NPDES Municipal Storm Water Permit #CAS029718. 34 970702 lac 0031587 Mitigation measure 4.9-5(b) recommends that applicants for all area projects of five acres or more, be required to prepare a detailed SWPPP under the State General Construction Activity Storm Water Permit. Mitigation measure 4.9-5(c) requires implementation of mitigation measures 4.9-1(a) through (c) for all Sand Hill Corridor projects. The recommended mitigation measures or equivalent measures have been incorporated in the conditions of approval for the Stanford West Apartments. The Council finds that adoption of these project -specific measures will lessen the project's contribution to potential cumulative sedimentation and contaminant impacts associated with construction to a less than significant level. Adoption of the recommended mitigation measures with respect to future development projects within the City's jurisdiction is beyond the scope of approvals granted for the Stanford West Apartments project; however, the Council finds that the City can and should require implementation of the recommended measures at the time future development projects are proposed. With respect to implementation of the recommended mitigation measures by jurisdictions other than the City, the Council finds that implementation of such measures is within the jurisdiction and responsibility of other public agencies and that the recommended measures can and should be implemented by these agencies to the extent feasible. These measures are generally consistent with requirements imposed by state law. However, because the nature and extent of potential area -wide cumulative impacts from future development are presently unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative effects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the Council. 4.9-6 increased impervious surfaces associated with development of the Stanford Sand Hill Road Corridor Projects and areas in the San Francisquito Creek Watershed could cumulatively increase surface runoff, potentially increasing the frequency and severity of existing downstream flooding. Mitigation measure 4.9-6 recommends that all jurisdictions regulating development in the San Francisquito Creek watershed require that adequate drainage and flood control facilities be provided for existing and planned development, in compliance with applicable General Plan goals and policies and ordinances and in coordination with Santa Clara Valley Water District (SCVWD) requirements. The Council finds that measures included in the project design and mitigation measures incorporated in the conditions of project approval, specifically an on -site retention basin and mitigation 35 970702 lac 0031587 • • measure 4.9-2, effectively implement the above recommended mitigation measure for the Stanford West Apartments project and will reduce the potential contribution of the project to cumulative flooding impacts to a less than significant level. Implementation of the recommended mitigation measure is beyond the scope of approvals granted for the project. However, the Council finds that the City can. and will consider adoption and implementation of appropriate mitigation measures as future development projects are proposed and in accordance with its comprehensive plan and zoning ordinances. With respect to implementation of the recommended mitigation measure by other jurisdictions in the San Francisquito Creek watershed, the Council finds that jurisdiction and responsibility for implementation of the recommended mitigation measure is vested in other public agencies and that such agencies can and should adopt and implement appropriate mitigation programs. Because the extent of potential cumulative impacts from future watershed development is currently unknown and because the Council cannot determine at this time the extent to which the adequate mitigation measures will be implemented by other agencies, the Council cannot presently determine whether the identified potential significant cumulative impact will be substantially lessened or avoided by the recommended mitigation. This cumulative impact therefore remains potentially significant. 4.9-7 Increased impervious surface associated with development of the Stanford Sand Hill Road Corridor Projects and areas in the San Francisquito Creek Watershed could cumulatively increase urban contorminAnts is surface runoff potentially reducing water quality. Mitigation measure 4.9-7(a) recommends that all local jurisdictions ensure that future project applicants include BMPs as part of project design in accordance with San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) requirements. Mitigation_ measure 4.9-7(b) notes that it is within the jurisdiction of the SFBRWQCB to require that comprehensive SWPPPs and monitoring programs be implemented by all storm water dischargers associated with specified industrial activities, in compliance with the State's General Permits, and to require that such plans shall include BMPs or equally effective measures. Mitigation measure 4.9-7(c) requires implementation of mitigation measures 4.9-4(a) and (b) by all approved Sand Hill Corridor projects. The conditions of approval for the Stanford West Apartments project incorporate each of the recommended project -specific mitigation measures or equivalent measures to mitigate identified potential cumulative contaminant impacts to San Francisquito Creek. The Council finds that adoption of these recommended measures will lessen the project's contribution to the identified cumulative impact to a less than significant level. The recommended mitigation measures have also been adopted in connection with 36 970702 lac 0031587 • • approval of the other approved Sand Hill Road Corridor projects, and will lessen the combined cumulative impact of the projects to a less than significant level. Adoption of the recommended mitigation measures for future development in the City is beyond the scope of approvals granted for the project. However, the Council finds that the City can and should adopt equivalent measures for all future projects approved within its jurisdiction. With respect to impacts resulting from future development outside the City, jurisdiction and responsibility for implementation of recommended mitigation measures or equivalent measures is vested in other public agencies. The Council finds that these jurisdictions can and should implement such measures. However, because the nature and extent of potential cumulative impacts from future development are presently speculative and unknown, and the degree to which other jurisdictions will implement recommended mitigation measures is uncertain, the Council cannot determine at this time the extent to which the recommended measures will be implemented outside the City's boundaries and also cannot determine the extent to which these measures, if implemented, will lessen or avoid the identified potential cumulative impact. This cumulative impact therefore remains potentially significant. 4.11 UTILITIES, ENERGY, AND INFRASTRUCTURE 4.11-3 The proposed projects could use water wastefully. Mitigation measure 4.11-3 requires that in order to reduce water consumption, the project design shall incorporate measures to maximize the efficient use of water and minimize total water consumption. Specific measures to be includedare the following: All landscape designs shall incorporate and address the City Landscape Water Efficiency Standards. The project sites would be subject to an annual maximum water allowance for landscaping. The project applicant shall coordinate with the City of Palo Alto Utilities Department, Resource Management Division to determine other conservation related improvements that would apply to the projects. The EIR concluded that because final plans have not been completed by the applicant specifying how water, particularly for landscaping, would be efficiently used, there existed a potential that water could be used wastefully by the project. The Council finds that the adopted mitigation measure will lessen this potentially significant impact to insignificance by ensuring that final landscaping and construction plans meet current City Water Efficiency Standards and incorporate additional conservation measures if recommended by City staff. 37 970702 lac 0031387 4.11-4 Construction of the proposed improvements could disrupt existing water services. Mitigation measure 4.11-4 provides that prior to the start of construction of infrastructure, the project applicant shall provide a plan for review and approval to the City of Palo Alto Director of Utilities outlining the approach to be taken to minimize the impact to existing utilities and customers. The EIR determined that operations necessary to connect infrastructure associated with the project to existing service lines and facilities could result in potentially significant interruptions of utility services for existing users, specifically interruptions of water service (Impact 4-11-4), wastewater service (Impact 4-11-11), electrical service (Impact 4-11-17) and gas service (Impact 4-11-24.) The Council finds that the adopted mitigation measure will lessen each of these potentially significant impacts to a less than significant level by requiring the applicant to submit and obtain approval of plans which will provide for completion of all utility connections for the project with the minimum necessary interruption of existing services. 4.11-7 Cumulative development could use water wastefully. Mitigation measure 4.11-7 provides that the City shall ensure that each new project approved within the City requiring ARB approval is required to be consistent with and implement the City policies and programs related to water conservation. The EIR concluded that existing City policies and programs are adequate to avoid cumulative wasteful use of water, and that a significant adverse impact had the potential to occur only if the City failed to continue to implement these policies and programs. The recommended mitigation measure provides that the City will continue to implement existing water conservation policies by making compliance a condition of ARB approval for all new projects. While implementation of this mitigation measure is beyond the scope of approvals granted for the Stanford West Apartments project, the Council finds that this mitigation measure can and should be implemented with respect to future projects within the City and will lessen the identified potentially significant cumulative impact to insignificance. 4.11-9 The proposed projects would require improvement of the existing 21 -inch wastewater line. Mitigation measure 4.11-9 requires that in the event that open -trench technology is used, the project applicant shall ensure that the new 24 -inch wastewater line is constructed coincident with, and placed in the right-of-way of, Palo Road, during Phase I of project construction, thereby avoiding potential biological impacts and conflicts with future uses associated with the alternate location of the line. 38 970702 lac 0031587 • The Council finds that adoption of this mitigation measure will lessen the potential significant adverse impacts associated with construction of a new 21" wastewater line to a less than significant level. This mitigation measure requires the applicant to either use technology which avoids trenching and resulting tree removal in the Stanford arboretum, or to relocate the route of the replacement pipeline along existing right-of-way containing no significant environmental resources in order to avoid impacts to the arboretum. 4.11-10 The proposed projects would generate additional wastewater flows that could exceed the capacity of the existing 27 -inch wastewater line. Mitigation measure 4.11-10(a) provides that if the proposed project is developed prior to the Palo Alto Medical Foundation (PAMF) project, the project applicant shall perform flow metering and a capacity study of the 27 -inch wastewater line, and shall be responsible for the costs of the improvement associated with the projects. All aspects of construction within the railroad right-of-way shall meet Peninsula Corridor Joint Powers Board (PCJPB)requirements and shall be approved by the PCJPB. Mitigation measure 4.11-10(b) provides that if the PAMF project is developed prior to the proposed projects, the project applicant shall coordinate with the Palo Alto Utilities Department and the PAMF project engineers to ensure that the proposed downstream 27 -inch wastewater line is enlarged with adequate capacity for the proposed Stanford West housing and Stanford Shopping Center Expansion projects. The EIR concluded that the project, in conjunction with the Stanford Shopping Center Expansion and proposed PAMF expansion project, would likely result in cumulative wastewater flows which exceed the capacity of the existing 27" wastewater line serving these projects. The Council finds that adoption of these mitigation measures will lessen this potential impact to insignificance by requiring the applicant to bear the costs of all improvements determined necessary to provide adequate wastewater line capacity for all three projects, and that all improvements within the railroad right-of-way crossed by the pipeline be constructed with the approval of the PCJPB, which maintains the rail lines. 4.11-11 Construction of the proposed improvements could disrupt existing wastewater services. Mitigation measure 4.11-11 requires implementation of mitigation measure 4.11-4, discussed above. See findings re mitigation measure 4.11-4_ 39 970702 lac 0031557 • • 4.11-13 Cumulative development could require major infrastructure improvements to the existing wastewater system. Mitigation measure 4.11-13(a) recommends that the City of Palo Alto Utilities Department ensure that developers responsible for construction of new wastewater lines coordinate with all other parties intending to utilize the line. Mitigation measure 4.11-13(b) recommends that sewer line capacity studies satisfactory to the City's Director of Utilities be conducted prior to initiating future cumulative development. Mitigation measure 4.11-13(c) recommends that all final designs for the sizing of new sewer mains shall be based on infiltration from a 20 -year storm and peak base wastewater flow. The EIR concluded that lack of coordinated planning for future development could result in failure to adequately size area wastewater lines, resulting in future need to again upgrade these lines to provide needed capacity. The recommended mitigation measures provide for full evaluation and correct sizing of mains prior to cumulative development. The Council finds that adoption of these measures will lessen the project's contribution to this potential cumulative impact to a less -than significant level. These mitigation measures will also lessen the overall potential cumulative impact to a less than significant level since implementation of these measures will result in provision of adequate long-term capacity for all reasonably foreseeable development. 4.11-17 Construction of the proposed improvements could disrupt existing electrical services. Mitigation measure 4.11-17 requires implementation of mitigation measure 4.11-4 for all Sand Hill Corridor projects. See findings re mitigation measure 4.11-4. 4.11-24 Construction of the proposed improvements could disrupt existing gas services. Mitigation measure 4.11-24 implementation of mitigation measure 4.11-4 for all Sand Hill Corridor projects. See findings re mitigation measure 4.11-4. 4.12 PUBLIC SERVICES AND SCHOOLS 4.12-4 Cumulative development would increase the annual number of fire suppression service calls to the Palo Alto Fire Department (PAFD) . Mitigation measure 4.12-4 identifies three alternative means for offsetting cumulative increased demands on Palo Alto Fire 40 970702 lac 003 Obi • • Department resources. Condition of approval 2.1 for the project adopt the third of these alternate means, specifically: The City will provide additional resources to the PAFD through the City's General Fund from the increased tax revenues generated by the Sand Hill Corridor projects and other future cumulative projects. The Council finds that adoption of this measure will lessen the identified cumulative impact on fire suppression services to a less than significant level for each of the Sand Hill Corridor projects and future development. Cost and revenue projections for the approved projects indicate that increased tax revenues from the projects and other potential future development will be more than adequate to fund additional resources for the PAFD necessary to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased PAFD resources identified in EIR mitigation measure 4.12-4, specifically (1) fair share applicant funding of new PAFD personnel, and (2) fair -share contributions from future projects, are not necessary based on current information to maintain adequate fire protection within the City and would result in imposing unnecessary special additional costs on new development. 4.12-5 Cumulative development would increase the annual number of medical emergency service calls to the PAFD. Mitigation measure 4.12-5 identifies two alternative means of covering costs of additional emergency medical services should increases in current personnel and/or equipment prove necessary to meet future demand. Condition of approval 2.m provide that the City shall adopt the second of these alternatives, specifically, the City shall provide additional rnedi-van resources to the PAFD if needed with general fund increases from tax revenues generated by the projects and other future cumulative projects. The Council has adopted the second of these mitigation alternatives for the Sand Hill Corridor projects. The Council finds that the adopted mitigation measure will lessen the identified potential cumulative impact on emergency medical services to a less than significant level. Cost and revenue projections indicate that increased tax revenues from the Sand Hill Corridor projects and other potential future development will be adequate to fund additional emergency medical resources as needed to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased emergency medical services identified in EIR mitigation measure 4.12-5, specifically that future development projects directly pay a fair share toward a medi-van unit or, is not necessary to maintain adequate level of emergency medical services based on current information. 41 970702 Lac 0031587 4.12-6 Increased construction traffic from cumulative development could reduce PAPD response times. Mitigation measure 4.12-6 provides that as part of the project approval process, the City of Palo Alto Department of Planning and Community Environment shall ensure the following: All projects coordinate with the PAFD and PAPD to prepare an emergency response plan for the construction period that specifies alternate emergency response routes to the project site and vicinity which meet the Departments' response time goals; and The Emergency Response Plan for all Sand Hill Corridor projects will specify procedures to allow simultaneous construction without increasing emergency response times to an unacceptable level. The Council finds that adoption of this mitigation measure will lessen the project's potential impact on PAFD emergency response times to insignificance. This measure ensures that detailed plans will be developed and implemented to ensure that existing or adequate alternative response routes will be kept open at all times to permit PAFD responses to all service areas within PAFD response time standards. 4.12-8 Design of the proposed projects could present security risks to occupants and police patrol personnel. Mitigation measure 4.12-8 provides that the applicant's lighting and landscaping plans will be reviewed with the Palo Alto Police Department (PAPD) to eliminate safety risks. The Council finds that adoption of this mitigation measure will lessen the identified potential safety impact to a less than significant level. This measure will ensure that qualified City police officers will review lighting and landscaping plans so that plans are designed to eliminate potential security hazards such as poorly lit areas along walkways. 4.12-10 Cumulative development would increase the annual number of police service calls to the PAPD. Mitigation measure 4.12-10 identifies three alternate means of funding additional police services to offset increased demand on Palo Alto Police Department resources. Condition 1.j of the project conditions of approval provides that the City shall adopt the second of these alternatives, specifically, the City shall fund additional PAPD resources from increased tax revenues generated by the projects and other future cumulative projects, The Council finds that adoption of this measure will lessen the potential cumulative impact of the project and of new development generally on police services to a less than significant level. Cost and revenue projections indicate that increased tax 42 970702 lac 0031587 • • revenues from the Sand Hill Corridor projects and other potential future development will be adequate to fund additional police resources as needed to maintain current levels of service throughout the City. 4.12-11 Designs of cumulative development projects could present security risks to occupants and police patrol personnel. Mitigation measure 4.12-11 recommends that the City Department of Planning and Community Environment ensure that future project lighting and landscaping are reviewed with the PAPD to reduce safety risks. The ARB shall provide final review and approval. This mitigation measure has been effectively implemented with respect to the Stanford West Apartments project through the adoption of mitigation measure 14.12-8. The Council finds that adoption of the measure will reduce the project's contribution to any potential significant cumulative impact to a less than significant level. This mitigation measure has also been adopted in conjunction with approval of the Stanford West Senior Housing project. Adoption of this mitigation measure as a policy governing review and approval of all future development within the City is beyond the scope of the decision and approvals granted for the Stanford West Senior Housing project. However, the Council finds that the recommended mitigation, measure can and should be implemented in relation to future development projects within the City. 4.12-12 Increased construction traffic from cumulative development could increase PAPD response times. Mitigation measure 4.12-12 requires implementation of mitigation measure 4.12-6 by all approved Sand Hill Road Corridor Projects. This mitigation measure has been implemented by adoption of mitigation measure 4.12-6 for the each of the approved Sand Hill Corridor projects. The Council finds that implementation of mitigation measure 4.12-6 will lessen the cumulative impact of construction of the projects on PAPD response times to a less than significant level. 4.12-13 The proposed projects would increase enrollments and associated resource demands on the Palo Alto Unified School District (PAUSD). Mitigation measure 4.12-13(a) recommends that the project applicant negotiate with the PAUSD for the following mitigation measures: Fair share funding for new classrooms and other costs not covered by statutory development fees; or Fair share of funding for the reopening of closed facilities. 43 970702 lac 0031587 Mitigation measure 4.12-13(b) recommends that the applicant negotiate with the PAUSD to fund its fair share of 11 new teaching positions in area schools. The Council finds that implementation of these measures is beyond the authority and control of the City and that adoption of these measures by the City is therefore infeasible. The City's authority to impose mitigation measures for school related impacts is restricted by state law. Implementation of the identified mitigation measures is dependent upon voluntary agreement between the applicant and PAUSD. Copies of communications between the applicant and PAUSD which have been received by the Council indicate that the applicant has initiated efforts to ascertain and potentially contribute a fair share of school costs resulting from implementation of the project which are not covered by increased tax revenues or development fees from the project. However, because implementation and effectiveness of the proposed voluntary mitigation remains uncertain, the Council finds that the identified impacts on public schools must be considered potentially significant. 4.12-14 Cumulative development, including the proposed Stanford West Apartments Project, would cause R -12th grade enrollments to exceed PAUSD school capacity of 916 students or 12 percent in year 2004-2005. The EIR proposed the adoption of mitigation measure 4.12-14 to mitigate this identified cumulative impact. Mitigation measure 4.12-14 recommends that the City adopt a policy that encourages all future developers to contribute their fair share over and above payment of the development fee to mitigate school impacts. The Council recognizes that cumulative impacts on public schools are potentially significant, and further finds that these impacts would remain potentially significant whether or not the suggested mitigation measure is adopted as a policy of the City since contributions by developers would remain voluntary regardless of City encouragement. Adoption of a City policy of encouraging future developers to contribute school mitigation funds in excess of mandatory development fees is beyond the scope of approvals for the Stanford West Apartments project; and the Council has not adopted this mitigation. However, the Council has taken substantial steps to encourage the project applicant to discuss and fund mutually acceptable mitigation measures with school district, and can and will continue to take similar steps to encourage voluntary additional contributions by developers of future projects with the goal of fully offsetting any impacts which cannot be mitigated through mandatory development fees and tax revenue increases associated with new development. 44 970702 iac 00315$7 • • 4.12-17 The operation of the proposed projects would increase solid waste generation in the City of Palo Alto requiring increased diversion to meet the goals of AB 939. Mitigation measure 4.12-17(a) requires that as a condition of project approval, the applicant shall prepare and obtain approval from the City Public Works Department of a landfill diversion management program that meets the diversion goals of the Source Reduction and Recycling Element (SRRE) and AB939. The program shall include specific provisions detailed in the EIR. Mitigation measure 4.12-17(b) recommends that the City require all new development projects to prepare operation recycling programs which will meet the AB939 diversion goal of 50 percent by 2000. The program shall include specific provisions detailed in the EIR. The Council finds that adoption of mitigation measure 4.12-17(a) will lessen the project's potential solid waste impacts to a less than significant level. This mitigation measure requires the applicant to develop, with City supervision, a plan which will ensure that solid wastes from the project are processed in a manner which ensure compliance with the recycling goals of AB939. Adoption and enforcement of mitigation measure 4.12-17(a) will also implement mitigation measure 4.12-17(b) with respect to' the project. Adoption of mitigation measure 4.12-17(b) as a policy governing review and approval of all future development within the City is beyond the scope of approvals granted for the Stanford West Apartments project. However, the Council finds that adoption of the proposed mitigation measure can and should be adopted in relation to future development projects within the City. 4.12-18 The proposed projects would increase solid waste generation in the City of Palo Alto during construction requiring increased diversion to meet the goals of AB 939. Mitigation measure 4.12-18 requires the applicant to prepare and implement a construction recycling plan approved by the City Public Works Department. The plan shall include specific steps to achieve the City's short-term SRRE diversion goal of 30-40 percent through various specified measures. The Council finds that adoption of this measure will lessen the identified potential solid waste impact to a less than significant level. The approved recycling plan will ensure that provision is made for recovering all recyclable wastes generated during construction, thus avoiding unnecessary placement of recyclable materials in landfills. 45 970702 lac 0031587 • • 4.12-19 Cumulative development anticipated by the City through Year 2010, including the proposed projects, would increase solid waste generation by 5.5 percent over 1995 levels to 155,650 tons per year based on the projected growth of population and employees. Mitigation measure 4.12-19(a) recommends that the City require significant new development projects to prepare construction recycling plans as part of the project approval process. The construction plan shall include specific steps to achieve the AB939 diversion goal of 50 percent by 2000 through various specified measures. Mitigation measure 4.12-19(b) recommends that the City require new development projects to prepare long-term operational recycling programs as part of project approval process. The programs should meet th A2939 diversion goal of 50 percent by 2000, and include various additional specified elements These mitigation measures have been effectively applied to the Stanford West Apartments project through the adoption of mitigation measures 4.12-17(a) and 4.12-18. The Council finds that adoption of those measures will reduce the project's contribution to potential cumulative solid waste impacts to a less than significant level. Adoption of mitigation measure 4.12-19(a) and 4.12-19(b) as policies governing review and approval of all future development within the City is beyond the scope of the decision and approvals granted for the Stanford West Apartments project. However, the Council finds that the proposed mitigation measure can and should be adopted in relation to future development projects approved by the City. 5.2 GROWTH INDUCING IMPACTS The EIR concluded that the Stanford West Apartments project will have a significant growth inducing impact in that upgrading of the existing 21" sewer line serving the project area to the 24" line necessary to serve the project and the Stanford West Senior Housing and Stanford Shopping Center Expansion projects will remove an obstacle to growth of the Stanford Medical Center, which has announced tentative plans for expansion. The EIR does not identify any potential mitigation measures for this growth -inducing impact. The 24" sewer line will be constructed with the minimum size pipe available with sufficient capacity to ensure adequate service of the approved Sand Hill Corridor development projects. Since excess capacity will still be provided by this sewer line which could facilitate expansion of the Stanford Medical Center or other development, this impact is significant. The EIR concluded that the overall set of roadway improvements may serve to remove an obstacle to development of the contemplated 400,000 square foot expansion of the Stanford Medical Center. The traffic impacts of such development of the Medical Center as well as the impacts of cumulative development along the Sand Hill corridor were considered in the cumulative impacts analysis contained in the EIR. The EIR finds the impacts of such cumulative 46 970702 lac 0031587 • • development within the Sand Hill corridor significant, as discussed elsewhere in these findings. 47 970702 lac 0031597 • PART II ALTERNATIVES TO TEE PROJECT The Council has also considered the alternatives to the project analyzed in the FEIR. Based on the following considerations, the Council has determined that all identified alternatives to the project are infeasible. The findings set forth below stating this Council's reasons for rejecting each alternative in favor of the project describe several separate grounds for rejecting each alternative, each of which this Council has determined constitutes an independent basis for this Council's decision to approve the project and to reject the proposed alternative. No Project - No Development This alternative assumes that no development is permitted on the proposed project site and the site remains vacant open space. The Council finds that this alternative is infeasible because: (1) The alternative would preclude development of needed affordable and market rate rental housing within the City; and (2) The alternative is inconsistent with longstanding City Comprehensive Plan designation of the property for residential development. Rejection of the project in favor of this alternative would necessarily defeat the project objective of providing new affordable and market rate rental housing in the area and would further defeat Stanford's objective of providing new rental housing for employees in close proximity to the Stanford campus, thus reducing vehicle travel for Stanford employees and improving the area's overall jobs/housing balance. Precluding residential development of the property would also be inconsistent with the City's existing comprehensive plan and zoning designations of the property which provide for residential development of 10-40 units per acre on the property. No Project - No Action This alternative assumes that the current development plan is rejected and future development permitted in accordance with existing zoning and comprehensive plan designations for the site. The City's existing comprehensive plan and zoning designations of the property allow development of 10-40 residential units per acre. The EIR assumes that development under this alternative would consist of 800-900 residential units. The Council finds that this alternative is infeasible for the following reasons. (1) By requiring preparation and processing of new development plans, the alternative would result in a 48 970702 Lc 0031587 • substantial, unacceptable further delay in production of needed affordable and market rate rental housing; (2) Development under this alternative would result in many worse environmental impacts than the proposed project due to increased development density and larger development footprint, increased traffic, air quality and other impacts associated with increased number of residents on the site. This alternative would not lessen any environmental impacts of the project but would in most cases result in more severe impacts and reduced ability to mitigate these impacts through preservation of view corridors, grassland habitat preservation, avoidance of archaeologically sensitive areas, and provision of on -site recreational open space. The site plan of the approved project has been substantially modified through the 1993-1994 public outreach process, subsequent review with City staff, and the 1996-1997 public review process to a site plan that will facilitate a sense of community, disperse traffic on a grid street network and accommodate substantial open space. Redesign to a more conventional multiple family development would likely result in the loss or reduction of these attributes of the approved project. The Council finds that the approved project represents an acceptable accommodation of competing community concerns for creation of housing and protection of community character and environmental values, and that any plan to accommodate greater amounts of housing would result in unacceptable impacts and conflicts with these community values. 75% Development Alternative This alternative consists of development of the project site at approximately 75% of the density of the approved project, or about 471 residential units. Due to reduced density, this alternative could reduce developed area by approximately 25%, allowing for an incremental reduction in most project impacts. However, there is no guarantee that reduced density development would necessarily result in a corresponding reduction in developed area on the site. Even assuming that substantial reduction in developed area was achieved, the project would still result in ,ignificant and unavoidable land use, visual and biological impacts due to the change in character, loss of open space and loss of grassland habitat which would result from any substantial development on the project site. The Council finds that this alternative is infeasible because: (1) The alternative would result in an unacceptable loss of needed rental housing units; and (2) Reduction of the project by approximately 157 units would result in continued demand and resulting pressure for construction of new housing within the City or 49 970702 1acD031587 • • sut ounding area, particularly pressure for development of new employee housing on existing open space areas on Stanford University lands. Implementation of this alternative would have the immediate unacceptable effect of eliminating needed rental housing units from the project. Construction of all units in the proposed project is required to assist the City in meeting its anticipated need for new housing units for the period 1996-2002. Projections prepared by the Association of Bay Area Governments, which serve as the basis for the City's 1990 Comprehensive Plan Housing Element and the draft Comprehensive Plan Housing Element currently being developed by the City quantify the City's fair share of regional housing demand for this period to be a total of 1244 new residential units, including 276 units for very low income residents, 208 units for low income residents, 299 units for moderate income residents and 461 units for above -moderate income residents. Evidence presented to the Council during the hearings on the project indicate that there is a particularly acute need for construction of new rental housing of the type offered by the project. This acute need for new rental housing is further confirmed by continuing very low vacancy rates of 1% or less for rental housing within the City which have been documented in the Housing Element Technical Document prepared in conjunction with the City's current draft Comprehensive Plan Housing Element. Elimination of approximately 157 units from the project would substantially and unacceptably impair the City's ability to provide needed new housing within the City and to contribute its fair share to satisfying state and regional housing demands. Implementation of the 75% density alternative also would not avoid the environmental impacts of the project which have been shown to be of greatest public concern, i.e. loss of undeveloped open space and related natural habitat and substantial visual and other impacts associated with change in character of the project site. Implementation of this alternative would result only in incremental reductions in many of the project's impacts, and in somewhat greater ability to mitigate certain impacts such as potential impacts to archaeological resources and loss of grassland habitat. The Council does not believe that these incremental reductions- in environmental impacts are significant enough to justify the substantial reduction in the number of housing units in the project. The Council finds that in the overall balance of growth management planning and environmental considerations, efficient use of the project site, which has been designated for housing development for many years in the City's Comprehensive Plan, for the maximum number of residential units which can be accommodated consistent with environmental and design constraints is preferable to reduced density development which will result in continued unmet demand and pressure for construction of affordable new housing, particularly new rental housing. 50 970702 lac 0031587 50% Development Alternative This alternative consists of development of the project site at approximately 50% of the density of the approved project, or about 315 residential units. Due to reduced density, this alternative could potentially permit reduction of developed area by approximately 50%, allowing for greater design flexibility and incremental reduction in most project impacts, including preservation of approximately 8 acres of additional grasslands as compared with the proposed project. However, there is no guarantee that a 50% reduced development density would necessarily result in a corresponding reduction in developed area on the site. Even assuming that a substantial reduction in developed area was achieved, the project would still result in significant and unavoidable land use, visual and biological impacts due to the change in character, loss of open space and loss of grassland habitat area which will result from any substantial development on the project site. The Council finds that this alternative is infeasible because: (1) The alternative would result in an unacceptable loss of needed rental housing units; and (2) Reduction of the project by approximately 315 units would result in continued demand and resulting pressure for construction of new housing within the City or surrounding area, particularly pressure for development of new employee housing on existing open.space areas on Stanford University lands. As in the case of the 75% development alternative, implementation of this alternative would have the immediate (only more severe) unacceptable effect of eliminating needed rental housing units from the project. Construction of all units in the proposed project is required to assist the City in meeting its anticipated need for new housing units for the period 1996-2002, and to offset the current acute shortage of rental housing. Elimination of approximately 315 units from the project would seriously and unacceptably impair the City's ability to provide needed new rental housing within the City and to contribute its fair share to satisfying state and regional housing objectives. While implementation of this alternative also would reduce most environmental impacts of the project, in some cases substantially, the alternative would not avoid the significant environmental impacts of the project which have been shown to be of greatest public concern, i.e. loss of undeveloped open space and related natural habitat and substantial visual and other impacts associated with change in character of the project site. The Council does not find that the incremental reductions in environmental impacts associated with -this alternative are significant enough to justify the loss of 315 housing units from the project. 51 970702 lac 0031587 • The Council finds that in the overall balance of growth management considerations, efficient use of the project site,, which has been designated for housing development for many years in the City's comprehensive plan, for the maximum number of residential units which can be accommodated consistent with environmental and design constraints, is preferable to reduced density development which will result in continued unmet demand and pressure for construction of affordable new housing, particularly rental housing. No Housing Alternative The EIR also examined a "no -housing" alternative which would have consisted of approving 160,000 square feet of new commercial space for the Stanford Shopping Center and approving the Sand Hill Road Extension and Related Roadway Improvements project while denying approval for the proposed Stanford West Apartments and Stanford West Senior Housing projects. The primary purpose for consideration of this alternative in the EIR was to examine the effects on the area transportation system of approving the proposed roadway improvements and proposed shopping center expansion elements of the Sand Hill Corridor projects, without the addition of traffic from housing projects. With respect to the Stanford West Apartments project, the Council finds that this alternative is infeasible for the reasons previously stated in reference to the No Project -No Development alternative. Housing With Limited Shopping Center Development The EIR also examined a "housing with limited shopping center expansion" alternative consisting of (1) approval of the Stanford West Apartments and Stanford West Senior Housing; (2) construction of 49,000 square feet of new Stanford Shopping Center space only; (3) without any of the roadway improvements proposed in the Sand Hill Road Extension and Related Roadway Improvements project. The Council does not consider this alternative to be an alternative to the Stanford West Apartments project. This alternative was evaluated in the EIR to examine the effects on the area transportation system of approving residential development and limited shopping expansion, without the benefit of major area roadway improvements proposed in the Sand Hill Road Extension and Related Roadway Improvements. This alternative is discussed in the findings relating to the Stanford Shopping Center project. AI tern to Sites: Campus West Site The Campus West alternative site is an undeveloped parcel owned by Stanford located south of Sand Hill Road and across from the Oak Creek Apartments which border the Stanford West Apartments site. The Campus West site is currently outside the jurisdiction of the City and entirely within the territory of the County of Santa Clara. The EIR considered relocation of both the Stanford West Apartments and Stanford West Senior Housing projects to this 52 970702 lac 0031587 • • site, and concluded that both could be substantially accommodated with extensive redesign and a probable increase in building heights. The EIR also noted that some reductions could be made in the total number of units approved on the West Campus site to better accommodate site constraints and provide for mitigation of impacts. However, for purposes of considering this alternative, the Council has assumed that all 628 units of the approved Stanford West Apartment project could be accommodated on the Campus West site without resulting in greater environmental impacts for this alternative than predicted in the EIR. In comments on the DEIR, some members of the public also commented that relocation of the Stanford West Apartments alone to this site would allow increased preservation of open space and design flexibility to mitigate or avoid potential impacts of development on the site. In considering this alternative, the Council has also considered the possibility of relocating the Stanford West Apartments project only to the Campus West site. The Council finds that Campus West alternative is infeasible for the following reasons. 1. The alternative is inconsistent with existing Santa Clara County and City of Palo Alto land use designations and policies for use of the site; and 2. Implementation of this alternative is uncertain and speculative and, even if implemented, would involve substantial unacceptable delay in development of needed new affordable and market rate housing. The Campus West site is presently designated in the Santa Clara County General Plan and Stanford's general use permit as "Major Educational and Institutional Uses." The land is also designated in Stanford's master land use plans for "Major Educational and Institutional Uses." Stanford's long term development plans for this property contemplate development of educational; research or other facilities directly related to the University's academic mission rather than non -University housing or income -producing uses. While other locations are available for expansion of existing academic uses on the Stanford campus, some of these lands are presently designated as open space and not approved for substantial new development. Because development of housing on the Campus West site is inconsistent with Stanford's existing long-term plans, it is uncertain that Stanford would attempt to implement this alternative if requested by the City. Failure by Stanford to pursue this alternative would result in loss of all new housing associated with the project.- If Stanford does elect to pursue this alternative, implementation would require submittal of an entirely new application and commencement of a new approval process by the County of Santa Clara, or by the City if annexation is proposed as part of the project. Due to the size of the project and potential environmental impacts of development at this alternate location, the approval process would necessarily involve a complete redesign of the project, a new environmental impact report and development review process, resulting in substantial 53 970702 lac 0031587 i delays in construction of any actual new housing. Because many of the potential impacts of this alternative, including traffic, loss of open space, loss of habitat area and change in character of the area are similar in nature to the impacts of the approved project, it is probable that implementation of the alternative would also be subject to public opposition similar to that encountered for the approved project. Development of rental housing on the Campus West site is inconsistent with existing County land use designation for the property. Under existing County policies and agreements between Stanford, the County and the City, any proposal for development of the housing project on the site would include annexation of the property to the City. Although the City would have primary final approval authority for the project, the City cannot prejudge its ultimate decision on any such application. Implementation of the alternative is therefore uncertain even assuming annexation is proposed. Because there is already a substantial and immediate need for additional housing in the City, the Council believes that the additional delay and uncertainty of implementation of this alternative are unacceptable and render the alternative infeasible. In determining this alternative to be infeasible, the Council has considered the limited potential environmental advantages of this alternative over the approved project and concluded that these advantages do not justify substantial further delay in providing needed housing. The EIR concluded that since the amount and type of development on the Campus West site would be similar to the approved project, the majority of impacts would remain approximately the same. Some impacts, such as impacts on cultural resources, riparian habitat and already less -than -significant noise and visual impacts on residents of Menlo Park would be further reduced or avoided by this alternative. As discussed on page 6.1- 65 of Volume 3 of the EIR, even though the site is partially screened from Sand Hill Road by a line of young Oak trees, the size of the buildings would be such that development of this site would change the existing rural character of the site to an urban character. It is not likely that mitigation could be provided for this impact. Because a portion of the site is presently undeveloped open space and contains extensive grasslands and oak habitat, significant impacts on land use, biological resources as well as the change in character of the area would still result from the alternative. These impacts would remain significant, although less severe, if the Stanford West Apartment project only were developed to the Campus West site without the addition of the Stanford West Senior Housing project. The Campus West alternative also would not preclude eventual development and resulting impacts of development at the Stanford West Apartments site for reasons discussed in relation to the No -Project alternative, and may therefore ultimately result in no net environmental advantage. Overall these incremental reductions in some impacts associated with the approved project do not justify continued delay in construction of needed new rental housing nor the risk of large-scale loss of potential housing units if this uncertain alternative is not ultimately approved and implemented. 54 970702 lac 0031587 Rickey's Hyatt Sand Hill Road/I-280 Alternative Site The EIR evaluated two additional alternative sites which could collectively be developed to accommodate the 630 units originally proposed in the Stanford West Apartments project. Two non -adjoining sites were considered as an alternative in recognition of the fact that there are no other parcels within the area, other than the proposed site and Campus West site, which are both large enough to accommodate the project and potentially available for housing development. Accommodation of the project at alternate sites other than the Campus West site would thus require division of the project into separate units and development at separate locations. Other potential alternate sites which could accommodate portions of the project were also considered during scoping for the project and determined to be infeasible. A summary of reasons for rejection of these other potential alternate sites appears in the EIR. The Council also finds that each of the potential alternative sites evaluated and rejected from further consideration during scoping for the EIR is not a feasible alternative site for the project for the reasons identified in the EIR. In considering the feasibility of the Rickey's Hyatt - Sand Hill Road/I-280 alternative, the Council has considered the feasibility of each siteseparately to determine whether either could feasibly be utilized to accommodate any portion of the project and therefore partially achieve the objective of providing new housing. The Council finds, for the reasons stated below, that neither of the two parcels could feasibly be utilized for a part of the development. The Council also finds that in the event that either one of the sites were determined to be feasible for a portion of the project, this proposed alternative would remain infeasible as a whole due to the unacceptable loss of housing units which would result from only partial development of the project at a single alternate site. In finding this alternative infeasible, the Council is aware that the EIR has designated this alternative as the environmentally superior alternative among those considered in the EIR. The Council finds, however, that the extremely uncertain and speculative nature of these alternatives, and the certainty of substantial additional delay in construction of needed new housing even if this alternative could be implemented, render the alternative infeasible despite its potential environmental advantages. In addition, this alternative would not preclude eventual development and resulting impacts of development at the Stanford West Apartments site for reasons discussed in relation to the No -Project alternative, and may therefore ultimately result in no net environmental advantage. Rickey's Hyatt Parcel: The Rickey's Hyatt site consists of an approximately 14 acre area east of El Camino Real and south of Arastradero Road which the EIR assumed could be developed to accommodate approximately 200 apartment units under current City zoning. The site is currently developed with a hotel and served by 55 9707021ac 0031587 • all necessary public services. The EIR indicates that because the site is already developed, implementation of this alternative would have substantially fewer environmental impacts than the approved project, although some impacts on neighboring residential uses could occur. The Council finds that development of the Rickey's Hyatt site as an alternative to the project is infeasible for the following reasons: (1) Implementation of this alternative is uncertain and speculative and would involve substantial unacceptable delay in development of needed new affordable and market rate rental housing; and (2) The alternative would not achieve Stanford's objective of providing new employee housing close to the existing Stanford campus. Although the site is located within the City and is presently zoned to permit residential development, Stanford does not presently own the Rickey's Hyatt site. Implementation of this alternative would thus require a lengthy and uncertain process of acquiring the site, preparing and processing development plans and conducting public environmental review. Because the outcome of this process cannot presently be fully predicted and is highly uncertain, this alternative is too speculative to be considered a viable alternative to the approved project by the Council. In addition, even if this alternative could be successfully implemented, the lengthy process of site acquisition, preparation of new plans and processing through City development review would result in unacceptable substantial delays in actual construction of needed new housing units. The location of this alternate site is also significantly distant from the Stanford main campus areas and too far from major Stanford facilities to provide for convenient pedestrian or bicycle access, thus defeating one of the objectives of the approved project. The Council recognizes that Stanford's objective of providing new housing for campus employees close to the Stanford campus is consistent with sound public planning policies and should be supported. Sand Hill Road/I-280 Parcel: The SHR/I-280 site consists of approximately 21 acres located within the City of Menlo Park near the intersection of Sand Hill Road and the 1-280 Freeway. The site is currently undeveloped and could physically accommodate approximately 430 apartment units but would have to be rezoned to permit such development. The Council finds that development of this parcel as an alternative to the project is infeasible for the following reasons: (1) The proposed alternative is inconsistent with existing zoning designations and planned use for the property; 56 970702 lac 0031587 • (2) Implementation of this alternative is uncertain and would involve substantial delay in development of needed new affordable and market rate rental housing; and (3) The alternative would not achieve Stanford's objective of providing new employee housing close to the existing Stanford campus. The Sand Hill Road/I-280 site is zoned for "Professional Administration and Office" uses under the City of Menlo Park's current zoning, but is presently undeveloped open space and rural in character. Stanford currently owns the property. However, implementation of this alternative would require preparation and processing of new development plans, new environmental review and approval of a rezoning by the City of Menlo Park. Because there is substantial uncertainty as to whether the City of Menlo Park would approve the proposed development, practical viability of this alternative is uncertain. In addition, commencement of an entirely new planning and approval process with the City of Menlo Park would result in unacceptable substantial delays in construction of needed new housing units. The location of this alternate site is also too far from the Stanford main campus areas to provide for easy pedestrian or bicycle access, thus defeating one of the objectives of the approved project. The Council recognizes that Stanford's objective of providing new housing for campus employees close to the Stanford campus is consistent with sound public planning policies and should be supported. Hoover Pavilion/Ei Camino Park Alternative At the request of the City's Planning Commission, Chapter 13 of the FEIR evaluated an alternative to the project consisting of locating the Stanford West Apartments project on two undeveloped parcels south of Sand Hill Road. The two proposed alternate sites consist of (1) the Hoover site, consisting of approximately 18.5 acres in the Stanford Arboretum lands surrounding the Hoover Pavilion, and (2) the El Camino Park site, consisting of 3 acres in El Camino Park. These sites were initially considered as possible alternative sites during scoping for the EIR, but were found not to be feasible alternate sites for housing at this time by City staff and therefore not discussed in the DEIR. The Council finds that the Hoover site and El Camino Park alternate sites, either collectively or individually, are not reasonable, realistic or feasible alternatives to theproject for the following reasons. Hoover Site (1) Development of housing on most of the site would be inconsistent with existing land use designations and planning policies of the County of Santa Clara, which presently exercises actual development control over the property, inconsistent with land use designations in the 57 970702 lac 0031587 • • City Comprehensive Plan which would apply in the event of annexation, and inconsistent with land use plans and policies of Stanford University. (2) Development of the site would result in unacceptable historic and aesthetic impacts on the Stanford Arboretum. (3) Implementation of the alternative is speculative and uncertain and would in any case result in unacceptable delays in development of needed new housing within the area. Approximately five acres of the proposed Hoover site is designated for possible housing development in the applicable land use plans of Stanford University. Development of this portion of the site alone, however, would result in unacceptable loss of housing units from the project. The County of Santa Clara's general plan and Stanford's general use permit designate most portions of the site for academic and open space uses, and consider most of these lands important for scenic beauty, visual relief and wildlife values, as well as for academic potential. Stanford's Land Use Plan designates the majority of the site Special Reserve and Open Space (Stanford Arboretum). Portions of the site are also designated as Special Condition Areas A (the El Camino Real frontage) and D (the Palm Drive, frontage), which both require a separate County Use Permit for any future development. Approximately 8 acres of the site are designated in Stanford's Arboretum Region Plan as "`Untouchable,' that is, having the highest historic significance." The City's Comprehensive Plan also contains policies which would apply to the property in the event of annexation to the City, and which establish the City's preferred use of the lands. These policies also preclude development of portions of the proposed Hoover site and require preservation of land included in the Stanford Arboretum as open space. These land use designations and policies reflect a long-term policy of preserving the Stanford Arboretum, which occupies a substantial portion of the site, as historically significant open space for the Stanford campus. The Council finds these policies are supported by important and valid historic, aesthetic and planning considerations which make development of the protected portions of the site unacceptable and infeasible. The Council recognizes that relocation of the project to the Hoover site would result in certain environmental trade-offs, including temporary preservation of the existing open space and grassland habitat area at the Stanford West Apartments site at the expense of loss of historic open space and a substantial number of trees at the Hoover site. The Council finds, however, that given the longstanding land use policies providing for development of the Stanford West Apartments site and favoring protection of the historic and aesthetic qualities of the Stanford Arboretum, the environmental trade-offs do not result in any net public benefit which would justify changes to the established land use plans and policies for the area. It is also uncertain whether Stanford University, as the owner of the site, would pursue this proposed alternative if requested to 58 970702 lac 0031587 • . do so by the City. Present agreements between the City and County of Santa Clara provide that development of the site for any income producing uses would be preceded by annexation to the City. While the City would therefore likely have final approval authority over any application for rental housing development on the Hoover site, the City cannot prejudge its ultimate decision on any such application, and implementation of the alternative is therefore uncertain even if annexation were proposed. Regardless of whether approval would ultimately be granted, redesign, reapplication and conduct of a new development review process for this alternative would result in substantial unacceptable delay in construction of needed new housing. EI Camino Park Site: The Council finds that development at the El Camino Park site is not a feasible alternative to the project for the following reasons: (1) Development of housing on the site would be inconsistent with existing City land use designations and policies governing the site; and (2) Implementation of this alternative is speculative and uncertain due to the requirement for a public vote to remove the existing park dedication status of the land, and would involve unacceptable delays in development of needed new housing. Implementation of this alternative would result in development of approximately 75 apartment units on 3 acres of publicly leased land in El Camino Park. The land is currently designated as Public Parks in the City's comprehensive plan and zoned PF (Public Facilities), and is dedicated park land under. the Palo Alto Municipal Code. Use of the land for other than park purposes may be approved only by majority vote of Palo Alto voters in a popular election. Because the outcome of the necessary popular election cannot be predicted, implementation of this alternative is unacceptably speculative and uncertain. In addition, even if approved by the voters, preparation and processing of new plans and completion of development review for this alternative would result in unacceptable substantial delays in actual construction of needed new housing. The Council also does not support conversion of dedicated park lands to non -park uses in the absence of some return benefit to public parks and recreation, such as might be obtained through a land exchange, or other overriding public benefits. No potential benefit to public parks or recreation has presently been identified for this alternative, and the Council therefore find this alternative unacceptable and infeasible on this additional policy ground. 59 970702 lac 0031587 Additional Alternatives Proposed In Public Comments Public Acquisition/Preservation A number of commenters during the EIR process proposed that the project site be preserved in an undeveloped state and dedicated to various uses such as a nature preserve, low -intensity public recreational space, gardens, or similar non -developmental types of uses or combinations of uses. In each of these cases the Council finds that the alternative is infeasible because the alternative would preclude the development of needed housing on the site and would be inconsistent with the City's longstanding Comprehensive Plan and zoning designations for the site. In addition, implementation of these suggested preservation alternatives would generally require acquisition of the site by a public or non-profit agency and ongoing expense for maintenance, insurance and other costs associated with property ownership. No commenter has identified a practical source of funds for either acquisition or subsequent improvement, maintenance and management of the site, nor does the Council believe that the acquisition and maintenance could be carried out with City funds and revenues without unacceptable impacts on other City programs. For these reasons the Council believes that preservation alternatives proposed by members of the public are not feasible, notwithstanding the understandable strong desire to preserve the site as open space. 60 970702 lac 003!587 EXHIBIT C STANFORD NEST SENIOR HOUSING PROJECT COUNCIL FINDINGS CONCERN/NG MITIGATION OF ENVIRONMENTAL IMPACTS AND CONSIDERATIONS OF ALTERNATIVES The City Council of the City of Palo Alto ("Council") has read and considered the Final Environmental Impact Report ("EIR") prepared for the Stanford West Senior Housing project. The EIR has been prepared for five projects including the Stanford West Apartments, Stanford West Senior Housing, Stanford Shopping Center Expansion, Sand Hill Road Extension and Related Roadway Improvements ("SHRE/RRI") projects, referred to collectively herein as the "Sand Hill Corridor projects," and the Pasteur Drive Parcel Annexation project. These projects are described in Chapter 3 of the EIR, and include, as approved by the Council, the changes and revisions described in Chapter 11 and in the "Final Summary of Project Changes" made a part of the EIR by the certifying resolution. Pursuant to Section 21081(a) of the Public Resources Code, the Council has considered each environmental impact of the Stanford West Senior Housing project identified in the EIR, and each of the mitigation measures and project alternatives evaluated in the EIR. The Council's detailed findings for each significant environmental impact or potentially significant environmental impact identified in the EIR are set forth below. Each significant or potentially significant environmental impact identified in the EIR is listed in bold. Those mitigation measures adopted or partially adopted by the Council are alse numbered in bold. The Council's reasons for rejection or partial rejection of certain mitigation measures and reasons for selection among alternative potential mitigation measures are described where appropriate. The Council's reasons for rejecting specific alternatives to the project identified in the EIR are stated in Part II of these findings. 1 970702 Ur 0031588 PART I CHANGES AND MITIGATION MEASURES ADOPTED TO REDUCE IMPACTS 4.1 LAND USE 4.1-5 Implementation of the proposed projects, in conjunction with cumulative development within the Sand Hill Road Corridor, would result in a change in character in the area. The SIR concludes that there are no feasible mitigation measures available which will substantially reduce the identified significant land use impacts and that the identified impact is therefore unavoidable. The Council also finds that although the Stanford West. Senior Housing project will not itself have a significant adverse impact on existing land use, the cumulative impact of changes to the existing character of the Sand Hill corridor resulting from the approved Sand Hill Corridor projects collectively will be significant. Changes and mitigation measures have been included in the Stanford West Senior Housing project which will lessen this cumulative impact. These measures are more fully discussed in findings pertaining to cultural, visual, transportation, noise and biological impacts and include measures such as those providing for replacement of trees removed during development of the project in order to maintain the existing wooded environment; tree planting and other landscaping along Sand Hill Road in order to visually screen project buildings with foliage, thus reducing the visual impact of new development on the site; modifications of the site plan to minimize already less than significant visual and noise impacts on Menlo Park residents across San Francisquito Creek and on adjoining uses; provision for bicycle and pedestrian access through the site to avoid interference with foot and bicycle travel and retention of existing historical features to the extent feasible. Despite these measures, however, the impact remains significant. 4.2 VISUAL QUALITY/LIGHT AND GLARE 4.2-1 The proposed projects would result in major visual changes within the Sand Hill Road corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-1(c) requires that final landscape plans for the project shall provide for planting of dense evergreen tree and understory plantings along Sand Hill Road to achieve maximum visual screening of the site. The mitigation calls for complete screening of the site by foliage when all plantings reach maturity. Mitigation measure 4.2-1(d) requires that landscape trees planted between Sand Hill Road and the proposed Health Care Center building be 20- to 24 -feet in height at the time of installation. 2 970702 lac 0031588 ! • Mitigation measure 4.2-1(e) requires that the entrance drive to the Health Care Center be redesigned to narrow it to the greatest extent feasible while continuing to meet functional traffic and traffic safety design standards. Large trees (20- to 24 -feet in height at installation) shall be planted alongside the entrance way. Mitigation measure 4.2-1(f) requires that large trees be planted along the Sand Hill Road facade of the eastern wing of the Health Care Center building. The Council finds that adoption of these measures will lessen the project's long term adverse impacts on views from Sand Hill Road to a less than significant level. The adopted mitigation measures provide for visual screening of the site from Sand Hill Road with trees and other natural vegetation. The Council also recognizes, however, that visual screening of the site will be incomplete until the required landscaping reaches maturity, and that the short-term impacts of the project on views from Sand Hill Road will therefore be significant. 4.2-3 Views of pedestrians and bicyclists on the pedestrian path/bikeway from the creek crossing to Sand Hill Road would be greatly altered from views of open space to a developed, urbanized environment. Mitigation measure 4.2-3 provides that the final landscape plans for the project shall include sufficient density, height, and proximity of proposed tree plantings to the east of the pedestrian path to screen project buildings from views of pedestrians and bicyclists on the path/bikeway. Tree plantings shall be designed to achieve canopy closure above and to the east of the pedestrian path. The Council finds that adoption of this measure will lessen the project's impact on views from the pedestrian/bicycle bridge, but will not reduce the impact to a less than significant level. The required landscaping will substantially screen views of buildings on the project site. However the required landscaping, particularly before trees reach maturity, will not completely eliminate views of new four story buildings or fully mitigate the resulting change in visual character of the area. The impact therefore remains significant. 4.2-8 Visual disturbance from construction of the proposed projects could have temporary adverse visual impacts. Mitigation measure 4.2-8 requires that on -site staging and storage of construction equipment and materials should be minimized to reduce visual disturbance during construction. Equipment and material storage that does occur on -site should be visually screened. Graded areas should be watered regularly to minimize fugitive dust. Construction should be staged and scheduled to minimize the duration of disturbance in each affected viewshed. 3 970702 lac 0031588 The Council finds that adoption of this mitigation measure will lessen the adverse visual impact of project construction, but will not reduce this impact to a less than significant level. The adopted mitigation measure will limit the duration and visibility of construction equipment and grading activities on the site, but will not eliminate the significant visual impact necessarily associated with major construction activities on the site. This impact therefore remains significant. 4.2-9 The proposed projects, in conjunction with cumulative development in the Sand Hill Road Corridor, could adversely affect the visual character of the corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-9 requires that mitigation measures 4.2-1(a-1) be implemented for all the Sand Hill Road Corridor Projects, including the Stanford West Senior Housing project. The Council has adopted or partially adopted the provisions of mitigation measures 4.2-1(a)-(1) as they pertain to the Stanford West Senior Housing project. The Council finds that the adoption of these mitigation measures will lessen the project's contribution to cumulative visual impacts from development of the Sand Hill Road corridor for reasons previously stated in relation to each adopted mitigation measure, but that these measures collectively will not reduce the project's contribution to cumulative visual impacts to a less than significant level. The additional project -specific mitigation measures recommended in mitigation measure 4.2-9 have been adopted or rejected as stated in the findings for the Stanford West Apartments, Stanford Shopping Center Expansion, and Sand Hill Road Extension and Related Roadway Improvements projects. To the extent these measures have been adopted, they collectively will reduce but not eliminate the significant adverse cumulative visual impacts of the Sand Hill Corridor projects. This cumulative impact therefore remains significant. The Council recognizes that future development, to the extent allowed in the Sand Hill Corridor area will continue to add to the significant cumulative visual impacts associated with the approved projects. 4.2-11 The proposed projects, in conjunction with cumulative development, could adversely alter views from the pedestrian/bicycle bridge crossing San Francisquito Creek to Menlo Park. Mitigation measure 4.2-11 provides that the applicant shall provide landscape screening of the Children's Health Council facilities from the bike path. The Council finds that adoption of this mitigation measure will lessen the project's contribution to cumulative impacts on views from the pedestrian/bicycle bridge, but will not reduce the 4 970702 lac 0031588 project's contribution nor the cumulative impact to a less than significant level. The required landscaping will substantially screen. views of the Children's Health Council, thereby reducing the overall visibility of buildings, but will not eliminate the remaining unavoidable substantial change in visual character of the area associated with development of the Stanford West Apartments and Stanford West Senior Housing project. The cumulative impact will therefore remain significant. 4.2-13 The proposed projects, in conjunction with cumulative development, could generate light and glare from buildings and roadways that could have adverse effects on nearby residents and on -coming drivers along Sand Hill Road. Mitigation measure 4.2-13 provides that interior and exterior light sources associated with all of the approved Sand Hill Corridor projects shall be shielded or directed in such a manner as to prevent visibility of the light sources and to eliminate light spillover beyond the perimeter of the proposed project. Specific measures recommended in accordance with section 18.64.030 of the Palo Alto Municipal Code include the following: (a) Exterior light fixtures on the housing buildings should be mounted no higher than 15 feet at the rear of the buildings. (b) Lighting of the building exterior and parking lot should be of the lowest intensity and energy use adequate for its purpose. (c) Unnecessary continued illumination, such as illuminated signs, should be avoided. (d) Timing devices should h. considered for exterior and interior lights in order to minimize light glare at night without jeopardizing security. The Council finds that adoption of this measure will lessen the project's contribution to potential cumulative light and glare impacts to insignificance. The adopted mitigation measure will have the effect of eliminating substantial spillover of light from the project site and will therefore reduce any potential cumulative impact to insignificance. This mitigation measure has also been incorporated into the conditions of approval for other approved Sand Hill Road Corridor projects and will therefore eliminate any potentialsignificant cumulative effect by confining the impacts of each project to its own location. 5 970702 lac 0031588 4.3 CULTURAL RESOURCES 4.3-1 Implementation of the proposed projects would result in damaging effects on important historic and/or prehistoric archaeological resources. Mitigation measure 4.3-1(b) requires that prior to development the applicant shall conduct a data recovery program on all areas in which construction is believed to have a potential to result in significant archaeological impacts. The program shall consist of an initial phase of intensive subsurface archaeological testing meeting minimum standards specified in the EIR. Significant resources encountered shall be subject to recovery, preservation and study as provided in mitigation measure 4.3-1(c). All work shall be subject to review and monitoring by an independent archaeologist engaged by the City. Mitigation measure 4.3-1(c) requires manual excavation and recovery of archaeological resources from any areas encountered during construction which are determined to hold important archaeological resources and for the recovery, preservation and study of these resources. The measure also provides for ongoing monitoring of construction activities in potentially sensitive areas of the site and for preparation of further detailed procedures to ensure protection and recovery of any significant resources encountered in such areas. The plans shall include (a) provisions for artifact cataloging, analysis, and curation; (b) identification and coordination with most -likely Native American descendants concerning monitoring and reburial of Native American remains, if any are encountered; (c) plans for preparation of technical reports; (d) analysis and preservation of artifacts and documentation and analysis of non -recoverable site features. All of the foregoing shall be performed in accordance with current scientific and professional standards. Mitigation measure 4.3-1(d) , as modified in p. 14-9 of the EIR, provides that any mechanical excavation for underground utility lines in Level 1 avoidance areas shall be conducted under the supervision of an archaeologist. If mechanical excavation is determined to pose a threat to archaeological resources, excavation will be conducted manually. Removed soil shall be screened and any artifacts recovered will be analyzed, reported and curated as provided in mitigation measure 4.3-1(c). Mitigation measure 4.3-1(e) limits the placement of paved bicycle or pedestrian paths or light -duty roads and specifies additional measures to ensure that no impacts will result from placement or construction of these paths or roads in areas likely to contain archaeological resources. Mitigation measure 4.3-1(f) provides that construction activities involving substantial ground disturbance (greater than 12" in depth) near any known archaeological site shall be subject to monitoring. 6 9707021u 0031388 • • Mitigation measure 4.3-1(g) provides that if previously unidentified cultural resources are discovered during construction, work shall cease in the immediate area until qualified archaeologists assess the significance of the resources and make mitigation recommendations (e.g., manual excavation of the immediate area) , if warranted. Mitigation measure 4.3-1(h) requires the applicant and contractors to comply with the requirements of Section 7050.5(b) of the California Health and Safety Code if Native American burials or other possible Native American human remains are located during construction. This code section requires that a Native American Most Likely Descendant (determined in consultation with the Native American Heritage Commission) be notified within 24 hours and appropriate provisions made for appropriate reburial. This and related sections of the Public Resources Code also provide that remains shall be protected from further construction work or vandalism. Mitigation measure 4.3-1(j) requires that recent information obtained by Stanford be consulted in the Archaeological Testing Plan for the site. Areas beneath existing buildings have not been subject to previous subsurface testing will be test following demolition of existing buildings and prior to new construction. The Council finds that adoption of these mitigation measures will lessen the project's impacts on archaeological resources to a less than significant level. While potentially significant archaeological resources are believed to exist on the project site and could be affected by development, the extent of such resources is not presently known. The archaeological resources in some areas are also likely to have been damaged or destroyed by past development. The adopted mitigation measures will ensure that any important archaeological resources encountered in areas subject to development will be identified, removed and preserved for further study in accordance with accepted scientific standards, ensuring no loss of scientific or historical value of the resources. The adopted measures also ensure that proper respect will be afforded - any burials and any other culturally important Native American remnants which might be impacted by the project. Rejected Mitigation Measure The EIR also proposed an alternate mitigation measure 4.3-1(a) which has not been adopted by the City. Mitigation measure 4.3-1(a) would require the Stanford West Senior Housing project to be redesigned to avoid disturbance to all buried intact or partially intact prehistoric or historic resources on the site. The Council finds that mitigation measure 4.3-1(a) is infeasible as it relates to the project because the measure would result in other environmental impacts and/or elimination of housing units from the project, without resulting in a countervailing net benefit in terms of protection of archaeological resources. Completion of studies to determine the full extent of surviving 7 970702 Jac 0031588 • • archaeological deposits on the site to guide project redesign would substantially delay construction of the project. In addition, depending upon the extent of surviving archaeological resources confirmed, redesign of the project could result in loss of housing units and/or other undesirable effects such as relocating buildings within setback areas closer to San Francisquito Creek: visual impacts from increased building heights or relocation, or loss of additional trees or loss of residential units or other facilities intended for the benefit of future senior residents of the project. Alternate mitigation measures are available and have been adopted to reduce potential impacts on archaeological resources to a less than significant level. The adopted mitigation measures will ensure that any important archaeological resources encountered in areas subject to development will be identified, removed and preserved for further study in accordance with accepted scientific standards, ensuring no loss of scientific or historical value of the resources. Because alternative measures have been adopted to avoid significant effects on archaeological resources, implementation of mitigation measure 4.3-1(a) is not necessary to avoid these impacts and cannot be justified in light of delays in project implementation and potential other adverse environmental effects discussed above. 4.3-3 Implementation of the proposed projects could result, in damaging effects on the Leland Stanford, Jr. Stone Monument. Mitigation measure 4.3-3(b) provides that the monument/mausoleum site shall be marked with a plaque, and the monument preserved and relocated on -site to an area open to public viewing as near to the original location as possible. The relocated monument will be incorporated in landscape plans to preserve and enhance its historical significance. Mitigation measure 4.3-3(c) provides that the remains of the original mausoleum shall be subject to an archaeological data recovery program. The Council finds that adoption of these measures will lessen the identified impact on historic resources to a less than significant level. The adopted mitigation measures provide for preservation of the Leland Stanford Jr. monument near its historic location, recording of its original location with a plaque and recovery of any surviving artifacts or other historically significant information associated with the present location of the monument and former mausoleum site. The Council believes that relocation of the monument on the site will not substantially diminish its historic value or significance. Rejected Mitigation: The EIR also identified an alternative mitigation measure 4.3-3(a), which would require redesign of the Stanford West Senior Housing project to permit the Stone Monument to be preserved where it is presently situated. The Council finds that this measure -is infeasible in that implementation of the measure could result in 8 9'70702 lac 0031588 increases in other impacts such as visual impacts from increased building heights or relocation, relocation of buildings closer to San Francisquito Creek, loss of trees, or loss of resiaential units or other facilities intended for the benefit of future senior residents of the project. As an alternative to this measure the Council has adopted mitigation measure 4.3-3(b), which provides for relocation and preservation of the monument near its present location. While the EIR concludes that the location of the monument is historically significant, the Council finds that the historic significance of the monument will not be substantially reduced by relocation on the site. The original historic location of the monument will continue to be marked with a plaque. 4.3-4 Implementation of the proposed projects could result in destruction of the Old Carriage House, the only remaining architectural feature from the Stanford Estate. Mitigation measure 4.3-4(a), as modified by condition 2f, requires that the Old Carriage House be fully protected and preserved in place. The applicant shall submit for approval plans which provide for fencing during construction and long term protection of the Carriage House. The applicant shall provide a bond or other financial security to ensure performance of this mitigation measure. The Council finds that adoption of these measures will avoid all potential adverse impacts to the Old Carriage House. The adopted mitigation measure provides for full protection and long term protection of this historic structure. 4.3-5 Implementation of the proposed projects could result in damaging effects on the Stanford Convalescent Home Gates. Mitigation measure 4.3-5(b) provides that if preservation of the stone entry gate pillars in their current location is not feasible, the gates pillars shall be moved on the site and incorporated into the project's landscape plan. The Council finds that adoption of this measure will lessen the project's potential adverse impacts on the Stanford Convalescent Home Gates to a less than significant level. This measure will preserve the gates on the site to permit continued public recognition of the entryway and to maintain their historic feeling and association within the project area. Since the gates have already previously been moved from their original location, the Council does not believe that further relocation will significantly reduce the historic value or significance of the gates. Rejected Mitigation Measures The EIR also proposed an alternate mitigation measure 4.3-5(a) which has not been adopted by the City. Mitigation measure 4.3-5(a) would require redesign of the entry to the Stanford West Senior Housing Health Care Center and Ronald McDonald House to 9 970702 lac 0031588 permit the convalescent home entry gates to be preserved where they are presently situated. The Council finds that this mitigation measure is infeasible because it would disrupt the project site plan, potentially resulting in loss of additional trees and increased visual impacts from relocation of access ways. The gates were not part of the original Stanford estate and have been relocated from their original location near El Camino Real to their current location. While the presence of the gates is considered to be an important reflection of the area's history, their location is not considered to be historically significant. The alternate mitigation measure 4.3-5(b) recommended in the EIR has been adopted instead and will provide for preservation of the pillars on the site by incorporation into the landscape plans for the site and will avoid any significant adverse impact without disrupting desirable features of the proposed site plans. 4.3-6 The proposed projects, in conjunction with other cumulative development projects in the San Francisquito Creek drainage, could result in damage or destruction of important prehistoric and historic cultural resources. Mitigation measure 4.3-6 recommends that all planning jurisdictions within the San Francisquito Creek drainage implement cultural resource testing and data recovery measures, similar to those described in mitigation measure 4.3-1 for projects involving development of sensitive cultural resource sites. The Council has adopted the recommended mitigation measure for the Stanford West Senior Housing project and all other approved Sand Hill Corridor projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level and will also lessen the cumulative impact of the Sand Hill Corridor projects collectively to a less than significant level. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with future projects approved by the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative impact from future projects on archaeological resources is presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented by such other public agencies or the extent to which these measures, if implemented, will lessen or avoid potential 10 970702 !ac 0031588 • cumulative cultural resources impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.4 TRANSPORTATION 4.4-2 Bicycle and/or pedestrian access and safety could be affected by development of the proposed projects. Mitigation measure 4.4-2(a) requires that the final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed and approved by the City's Chief Transportation Official to ensure the circulation system will function as a part of regional or inter -city bicycle and pedestrian connections. Mitigation measure 4.4-2(e) provides that for five years following project construction, the project applicant will fund an annual review of reported traffic accident data at the Sand Hill Road/I-280 interchange to determine whether a significant increase in bicycle/auto conflicts has occurred. If an increase is documented, the applicant will work with Caltrans, the City of Menlo Park and San Mateo County to design and obtain funding for safety improvements required to minimize these conflicts. The Council finds that adoption of these measures will lessen the project's impacts on pedestrian and bicycle travel to a less than significant level. The adopted mitigation measures ensure that the final project design will provide for. safe bicycle and pedestrian access to, from and through the project site to local and regional bicycle and pedestrian paths, including those being implemented in conjunction with other elements of the Sand Hill Corridor projects. These measures also require Stanford to work with responsible agencies to eliminate safety problems resulting from increased bicycle and vehicle traffic at the Sand Hill Road/I-280 intersection if such problems are determined to exist in the future. 4.4-7 Development of the proposed projects could degrade the level of service of study area intersections, and contribute to increased intersection delay. The studies and analysis performed for the FEIR demonstrate that the project, either singly or in conjunction with other approved Sand Hill Corridor projects, will not have significant adverse effects on levels of service at most intersections near the project site. The FEIR concluded, however, that changes and increases in traffic patterns resulting from the Sand Hill Road Corridor projects collectively will result in significant adverse changes in traffic conditions at a total of seven area intersections, specifically: - Arboretum Road/Galvez Street El Camino Real/Page Mill Road - El Camino Real/Ravenswood Avenue 11 970702 lac 0031588 • • El Camino Real/Valparaiso Avenue/Glenwood Avenue Junipero Serra Blvd./Alpine Road/Santa Cruz Avenue Middlefield Road/Willow Road Sand Hill Road/Santa Cruz Avenue The Stanford West Senior Housing project alone will have significant adverse impacts on traffic levels at only four area intersections, specifically: Arboretum Road/Galvez Street. El Camino Real/Page Mill Road Middlefield Road/Willow Road Sand Hill Road/Santa Cruz Avenue The conditions of approval nevertheless require the applicant to contribute to all of the following mitigation measures. Arboretum Road/Galvez Street: Mitigation measure 4.4-7(a) requires the applicant to install a traffic signal or other appropriate traffic control device(s) at the intersection of Arboretum Road/Galvez Street, and pay the full cost of these improvements. This measure shall be implemented when the intersection satisfies appropriate signal warrants as determined by the Chief Transportation Official. In the event that the City and the. applicant determine that use of a traffic circle or "roundabout" will provide for the same or better LOS and safety as a traffic signal, the traffic circle may be constructed at the applicant's expense instead of a traffic signals or other traditional traffic control device(s). El Camino Real/Page Mill Road: Mitigation measure 4.4-7(b) requires the applicant to contribute a fair share of the costs of the following planned improvements: Add a southbound right turn lane. - Add a westbound right turn lane. Add a northbound right turn lane; and extend the westbound left turn lane by 100 feet. These measures should be implemented when the intersection approaches LOS F, as evaluated through periodic monitoring to be carried out by the applicant on behalf the City. Sand Hill Road/Santa Cruz Avenue: Mitigation measure 4.4-7(c) requires the applicant to pay a fair share of the costs of the following improvements to the following improvements to the Sand Hill Road/Santa Cruz Avenue intersection: Widen Sand Hill Road to add second eastbound left turn lane; Widen Sand Hill Road to add second westbound left turn lane; 12 970702 lac 0031585 Modify signal phasing; Install an exclusive right turn lane on the northbound approach of Santa Cruz Avenue; and Provide dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. The applicant shall also pay the costs of installing an exclusive right turn lane on the northbound approach of Santa Cruz Avenue and providing dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. Conditions of approval l.c and 12 for the Sand Hill Road Extension and Related Roadway Improvements project, and adopted by condition of approval 2.d for this project, provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the. County of San Mateo, with respect to any improvements within that jurisdiction, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share (subject to limits based on engineering estimates) based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue: Mitigation measure 4.4-7(d) requires the applicant to pay a fair share of the costs of the following improvements to the Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue intersection mandated by the Menlo Park General Plan or recommended in the EIR: Widen northbound approach to add exclusive right turn lane. - Install an additional southbound left -turn lane. Conditions of approval 1.c and 12 for the Sand Hill Road Extension and Related Roadway Improvements project, as adopted by condition of approval 2.d for this project, provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, as applicable, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share (subject to limits based on reasonably engineering estimates) based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Middlefield Avenue/Willow Road: Mitigation measure 4.4-7(e), identifies a num:1er of improvements which would be necessary to 13 970702 lac 0031388 mitigate cumulative traffic impacts at this intersection, including the following: Add a second southbound left turning lane. Restripe eastbound approach. Modify signal phasing, including a leading left turn phase in the signal phasing for the north and south directions. The timing of these improvements will be determined by the City of Menlo Park, through periodic monitoring and/or through subsequent environmental impact analysis and documentation. Condition 2.e of the conditions of approval partially implements this mitigation measure by requiring that the applicant shall either make signal timing improvements sufficient to return traffic levels of service at this intersection to level of service D, or to contribute its fair share of the costs to construct the recommended intersection improvements. This obligation would not be triggered until current level of service falls to E or worse. Sand Hill Road/Santa Cruz Avenue and Junipero Serra Blvd./Alpine Road: Mitigation measure 4.4-7(h) provides that the applicant shall conduct an operational analysis of the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections to identify the appropriate combination of roadway and traffic signal improvements necessary to improve operation to LOS D during peak hours, if feasible. The EIR also recommends that the following mitigation measures be implemented to mitigate cumulative traffic impacts at specified intersections within the City of Menlo Park, but does not provide for direct participation by the applicant in implementation of these mitigation measures. El Camino Real/Ravenswood Avenue: Mitigation measure 4.4-7(f) recommends that the following improvements to the El Camino Real/Ravenswood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: Widen northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. Widen westbound approach to add exclusive right turn lane. El Camino Real/Valparaiso Avenue/Glenwood Avenue: Mitigation measure 4.4-7(g) recommends that the following improvements to the El Camino Real/Valparaiso Avenue/Glenwood Avenue intersection be 14 970702 lac 0031588 completed as prescribed in the City of Menlo Park's general plan: Restripe northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. Widen westbound approach to add exclusive right turn lane. Final design shall include provisions for bicycle traffic. In addition, the EIR recommends that signal phasing at this intersection be modified to include split phasing in the east/west direction and a leading left turn phase in the north/south direction. The Council finds that these adopted mitigation measures, if implemented, will lessen the project's impacts on traffic at the four significantly affected intersections to a less than significant level, and will also substantially lessen the impact of the project's contribution to cumulative traffic at other intersections significantly affected by the Sand Hill Corridor projects collectively. Mitigation measures 4.4 -7(a) -(e), as modified by conditions of approval, require the applicant to pay all or a fair share of the costs of physical improvements necessary to enable each of the intersections, as noted, to serve anticipated cumulative traffic demands at acceptable levels of service. Mitigation measure 4.4-7(h) also provides for identification of. appropriate additional intersection improvements should the City of Menlo Park elect to achieve a higher level of service and the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections. The Council recognizes that final authority to approve and implement the identified mitigation measures at three of the four intersections significantly affected by the project is vested in public agencies other than the City, specifically the County of Santa Clara (mitigation measure 4.4-7(a), Arboretum Road/Galvez Street); the City of Menlo Park (mitigation measures 4.4-7(c), Sand Hill Road/Santa Cruz Avenue and 4.4-7(e), Middlefield Avenue/Willow Road); and County of San Mateo (mitigation measure 4.4-7(c), Sand Hill Road/Santa Cruz Avenue). Responsibility and authority for implementing the recommended mitigation measures at the additional intersections cumulatively impacted by the project is also vested in other public agencies, specifically the City of Menlo Park (mitigation measures 4.4-7(f), El Camino Real/Ravenswood Avenue, and 4.4-7(g), El Camino Real/Valparaiso Avenue/Glenwood Avenue) and 4.4-7(d), Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue). The Council finds that the identified mitigation measures can and should be approved and implemented by these agencies. However, the Council also recognizes that in the event that one or more of the listed mitigation measures are not approved and implemented by the 15 970702 lac 0031588 appropriate responsible agency, the project will result in significant adverse impacts on the Arboretum Road/Galvez Street, Middlefield Avenue/Willow Road and/or Sand Hill Road/Santa Cruz Avenue intersections, and could contribute to significant impacts at other intersections cumulatively affected by the Sand Hill Corridor projects. Because it cannot presently be determined if or when the appropriate mitigation measures will be implemented by the respective responsible agencies, these impacts are considered by the Council to be potentially significant. 4.4-8 Construction activities could lead to both temporary disruption of transportation system operation, as well as to permanent damage to elements of the system such as pavement and bridges. Mitigation measure 4.4-8(a) requires the applicant to provide adequate off-street parking for -all construction -related vehicles throughout the construction period. If adequate parking cannot be provided on the construction sites, a satellite parking area shall be designated, and a shuttle bus shall be operated to transfer construction workers to the job sites. Mitigation measure 4.4-8(b) provides that construction activities related to the project are prohibited from substantially limiting pedestrian access (e.g, by blocking pedestrian routes), without prior approval from the City of Palo Alto and/or Caltrans. Any approval shall require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4-4.8(c) provides that the applicant shall be prohibited from limiting bicycle access (e.g. by blocking or restricting existing routes) while constructing the project, without prior approval from the City of Palo Alto or Caltrans and/or the City of Menlo Park (depending upon the jurisdiction of the requested action). Any approval will require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(d) provides that the applicant shall be required to prohibit or limit the number of construction material deliveries from 7 a.m. to 9 a.m., and from 4 p.m. to 6 p.m. on weekdays. Mitigation measure 4.4-8(e) provides that the applicant shall be required to prohibit or limit the number of construction employees from arriving or departing the site from the hours of 4:30 p.m. to 6 p.m. Mitigation measure 4.4-8(f) requires that all construction -related equipment and materials shall be delivered and removed on truck routes designated by the cities of Palo Alto and Menlo Park. Heavy construction vehicles shall be prohibited from accessing the sites from other routes. 16 970702 lac 0031388 • Mitigation measure 4.4-8(g) requires the applicant to repair any structural damage to public roadways, returning any damaged sections to original structural condition. The effectiveness of this measure shall be guaranteed by requiring surveys of road conditions before and after construction. Mitigation measure 4.4-8(h) prohibits the applicant from limiting access to public transit (e.g. by relocating or restricting access to bus stops or transfer facilities), and from limiting movement of public transit .vehicles, without prior approval from the Santa Clara Transit Agency or other appropriate jurisdiction. Any approval will require submittal of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(I) provides that in lieu of mitigation measures 4.4-8(a) through (h), the project applicant may prepare detailed construction impact mitigation plans for approval by the City of Palo Alto Chief Transportation Official and City of Menlo Park Transportation Manager prior to commencing any construction activities with potential transportation impacts in their respective jurisdictions. The plan must address all aspects of construction traffic management necessary t� eliminate or reduce transportation impacts to acceptable levels. _ The Council finds that adoption of these measures will lessen the project's potential construction phase traffic .and transportation impacts to a less than significant level. These measures provide for comprehensive planning for construction traffic and establish standards, criteria and implementing measures which will ensure that significant interference with vehicle,. bicycle, pedestrian and emergency vehicle access is avoided during all phases of construction. 4.5 AIR QUALITY 4.5-1 The PMZo generated during the construction of the proposed projects could be harmful to nearby pollutant -sensitive land uses. Mitigation measure 4.5-1 requires the applicant to implement a construction phase program which includes the following measures to reduce generation of particulate matter on the project site during construction: Water all active construction areas at least twice a day, or as needed to prevent visible dust plumes from blowing off -site. Use tarpaulins or other effective covers for on -site storage piles and for haul trucks on public streets. Pave, apply water, three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas during construction. 17 970702 lac 0031588 • Sweep all paved access routes, parking areas, and staging areas daily (preferably with water sweepers). Sweep streets daily (preferably with water sweepers) if visible amounts of soil material is carried onto public streets. If the working area of any construction site exceeds four acres at any one time, implement the following additional measures: Apply (non-toxic) soil stabilizers to inactive construction areas. Enclose, cover, water twice daily, or apply (non-toxic) soil binders to exposed stockpiles. Limit construction site vehicle speed to 15 mph on unpaved areas. Replant vegetation in disturbed areas as quickly as possible. If the working area of any construction site is located near any sensitive receptors, implement the following measure in addition to those listed above: Suspend excavation and grading activity when winds exceed 25 mph. The last mitigation would be applicable to the Sand Hill Road widening where it passes the 14 single family homes in Menlo Park between Santa Cruz Avenue and Oak Avenue. The Council finds that adoption of this measure will lessen the identified potential adverse construction phase impact to a less than significant level. Implementation of twice daily watering has been shown to reduce construction site PM10 emissions by at least 50 percent. This practice, in conjunction with the other listed measures, will reduce PM10 emissions during construction to less than the BAAQMD threshold of significance of 80 lbs/day for all anticipated construction activity. 4.5-2 ROG, NOx, and PMw emissions generated by motor vehicles and residential stationary sources associated with the proposed projects would exceed the 80 lbs/day threshold and could hinder regional and local attainment of State ozone and PMIJ standards. Mitigation measure 4.5-2 (a) requires the City to implement mitigation measure 4.4-2(a), which provides that final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed to ensure the circulation system will function as a part of regional or inter -city bicycle and pedestrian connections, thereby promoting increased use of bicycles or pedestrian travel by area residents. 18 970702 Lac 0031588 • The EIR concludes that air pollution emissions from the project, resulting primarily from increased project -related vehicle traffic -- would be approximately 31 lbs/day-for reactive organic compounds (ROG), 30 lbs/day for nitrogen oxides (NOx) and 29 lbs/day of PM,0 particulates, all below the threshold of significance recognized by the BAAQMD and utilized in the EIR. Due to continuing changes in automotive technology, it is further expected that emissions would drop to 15 lbs/day of ROG, 29 lbs/day of NOx and 29 lbs/day of PM10 by the year 2010. The project individually therefore will not have a significant adverse effect on air quality. The EIR also concluded, however, that the project would contribute to significant cumulative air quality impacts from the Sand Hill Road Corridor projects as a whole. The Council finds that this cumulative air quality impact is significant. 4.5-2 ROG, NOx, and Pao emissions generated by motor vehicles and residential stationary sources associated with the proposed projects would exceed the 80 lbs/day threshold and could hinder regional and local attainment of State ozone and Min standards. The EIR concludes that air pollution emissions from the project --almost entirely from related vehicle traffic --would be approximately 55 lbs/day for reactive organic compounds (ROG), 65 lbs/day for nitrogen oxides NOx and 51 lbs/day of PMI0 particulates, all below the threshold of significance recognized by the BAAQMD and utilized in the EIR. Due to continuing changes in automotive technology, it is further expected that emissions would drop to 26 lbs/day of NOx and remain at 51 lbs/day of PM10 by the year 2010. The project, therefore, will not individually have a significant adverse effect on air quality. The EIR also concluded, however, that the project would contribute to significant total air quality impacts from the Sand Hill corridor projects as a whole. Mitigation measure 4.5-2(a) requires the City to implement mitigation measure 4.4-2(a), which provides that final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed to ensure the circulation system will function as a part of regional or inter- city bicycle and pedestrian connections, thereby promoting increased use of bicycles or pedestrian travel by area residents. The Council finds that this measure will lessen project related air pollution impacts somewhat, but will not reduce the cumulative impact of the Sand Hill corridor projects to less than significant levels. The cumulative air quality impacts of the Sand Hill corridor projects will, therefore, be significant. 19 970702 lac 0031388 • 4.5-4 Cumulative daily traffic along major roadways in the project and study areas would emit more NOx, and PM6 with the implementation of the Sand Hill Road Projects, but emissions of ROG would decrease. The EIR found that the Sand Hill Road Corridor projects would collectively contribute to significant cumulative increases of emissions of NOx and PM/0 in the project area. The project's contribution to these cumulative impacts has been discussed in relation to.Impact 4.5-2. Cumulative traffic -related air pollution emissions are regulated through means beyond the City's jurisdiction and control. Individual vehicle emissions and automotive fuels are subject to regulation only by state or federal government. Regional traffic levels are also heavily influenced by past and future planning and land use decisions over which the City has no control. The Council therefore finds that no additional feasible mitigation measures are presently available to the City to mitigate the cumulative impact due to increases in regional traffic, and legal authority and responsibility for feasible mitigation measures, if any, is vested in other public agencies. This cumulative impact is therefore significant. 4.6 NOISE 4.6-1 The noise generated during the construction of the proposed projects could be disruptive to nearby noise -sensitive land uses. Mitigation measure 4.6-1(a) provides that construction activities will be limited to the hours of 8:00 a.m. to 8:00 p.m. Monday through Friday, and if weekend work is necessary, to the hours of 9:00 a.m. to 8:00 p.m. on Saturday, and to the hours of 10:00 a.m. to 6:00 p.m. on Sunday. Mitigation measure 4.6-1(b) provides that construction equipment shall be outfitted and maintained with noise reduction devices (i.e., mufflers, enclosures for stationary equipment, etc.) to obtain at least an average 10 dBA reduction shown feasible in Table 4.6-5. Mitigation measure 4.6-1(c) provides that stationary noise sources (e.g., compressors, concrete mixers, etc.) shall be located on portions of the sites furthest away from residential and other noise -sensitive areas, and that acoustic shielding shall be used with such equipment. The Council finds that adoption of these measures will substantially lessen construction phase noise impacts on surrounding residents, but will not reduce these impacts to less than significant levels. The measures will reduce noise generated by construction activities and will eliminate construction noise during normal sleeping hours. However, construction noise impacts will remain significant due to the levels of noise inherently generated by large scale construction activity and heavy equipment. 20 970702 lac 0031388 • • 4.6-3 Traffic generated by the proposed projects and other cumulative developments and the traffic accommodated by the proposed roadway improvements would impact existing and proposed residential and other sensitive land uses adjacent to roadways in the project and study areas. Mitigation measure 4.6-3(a) requires that project residential units facing Sand Hill Road contain sufficient acoustic insulation to meet State Title 24 indoor noise standards. The Council finds that the adopted mitigation measure will eliminate any potential significant noise impacts on project residents by requiring noise protection to be built into residential units to reduce interior noise levels to acceptable levels. The EIR concluded that although some residences in the area of the Sand Hill Corridor projects would experience significant cumulative noise impact from expected traffic increases on area roadways, the contribution of the Stanford West Senior Housing project to these cumulative noise impacts would be less than significant. The EIR also concluded that although the project would not directly cause significant noise impacts, traffic from the project would contribute to cumulative noise impacts on some residences along Sand Hill Road. The conditions of approval for the project, therefore incorporate the following mitigation measures to assist in mitigating potential cumulative traffic -related noise impacts. Mitigation measure 4.6-3(b) requires the applicant to construct a landscaped buffer strip with at least a 3 -foot -high berm along Sand Hill Road between Stanford Avenue and Oak Avenue in conjunction with implementation of the Sand Hill Road widening and realignment between Santa Cruz and Oak Avenues. Mitigation measure 4.6-3(c) requires the applicant to construct a soundwall 6 feet high or higher between Santa Cruz Avenue and Stanford Avenue in conjunction with implementation -of the Sand Hill Road widening to reduce noise from traffic increases at the nearby intersection. Mitigation measure 4.6-3(d), as modified by Condition 2.g of the project conditions of approval, requires the applicant to monitor noise increases in residences in the designated areas along Sand Hill Road where the Sand Hill Road Corridor projects may be responsible for more than 50%. of potential increases in traffic -related noise. If noise increases are detected, the applicant shall be responsible for the costs of measures such as additional insulation, double -glazed windows, or individual soundwalls as determined necessary by acoustic study to return interior noise levels in these residences to pre -project levels or to 45 dBa. Residents may also contribute any further funds necessary to further reduce interior noise levels to acceptable levels. 21 970702 Lsc 003! 588 The Council finds that these mitigation Measures, if implemented, will substantially lessen significant cumulative traffic -related -noise impacts along the -Sand Hill Road corridor although these measures will not necessarily reduce cumulative noise impacts to a less than significant level for every residence affected by the project. Mitigation measure 4.6-3(d) provides for a fair share contribution by the applicant to the costs of physically upgrading affected residences with noise mitigation measures. Mitigation measures 4.6-3(b) and 4.6-3(c) provide for construction of physical barriers to reduce noise to acceptable levels at protected residences. The adopted mitigation measure 4.3-6(d) will impose responsibility for necessary monitoring of actual noise increases on the applicant and also imposes responsibility on the applicant to pay a share of actual mitigation costs in proportion to the applicant's responsibility for these impacts where the Sand Hill Corridor projects are the predominant cause of cumulative traffic -related noise impacts. The Council does not believe that the applicant can or equitably should be held responsible for more than a fair share of the costs of mitigating these potential cumulative noise impacts. Revisions made by the City to'mitigation measure 4.3-6(d) are intended to strengthen the measure by fixing responsibility for noise monitoring on the applicant, and to also amend the measure to provide that the applicant shall be financially responsible only for fair share of the costs of implementing the mitigation measure. The Council recognizes that mitigation measure 4.6-3(d), as adopted, will not result in lessening of cumulative noise impacts at locations at which less than 50% of the cumulative traffic -related noise increase is attributable to the Sand Hill Corridor projects. The Council also recognizes that since implementation of mitigation measure 4.6-3(d) also requires the cooperation of affected homeowners, the physical improvements necessary to reduce noise levels at some affected residences to acceptable levels may not be constructed by choice of the owner. The Council therefore recognizes that notwithstanding adoption of the identified mitigation measures, cumulative traffic -related noise impacts may remain significant for some residences affected by the projects. With respect to mitigation measures 4.6-3(b) and 4.6-3(c), which will mitigate noise impacts on certain residences in Menlo Park, the Council further recognizes that although the conditions of approval require the applicant to accept responsibility for implementation of these mitigation measures, approval for implementation of these measures must be obtained from the City of Menlo Park. The Council finds that implementation of these mitigation measures can and should be approved by the City of Menlo Park. The Council also recognizes, however, that in the event that approval for implementation of these measures is not obtained from Menlo Park, affected residences in Menlo Park would experience significant cumulative traffic -related noise impacts due to increased cumulative traffic on Sand Hill Road. 22 970702 lac 0031388 4.7 BIOLOGICAL Rwomitam 4.7-1 Implementation of the proposed projects would result in loss of trees and associated wildlife habitat. Mitigation measure 4.7-1(a) requires that native trees removed for the projects shall be replaced at a ratio of 3:1 on a per acre basis by the same species from locally collected stock, and provides for additional replanting if survival rates fall below 80 percent. Mitigation measure 4.7-1(b) requires that non-native landscape trees removed for the projects be replaced on a two -to -one basis. Mitigation measure 4.7-1(c) provides that the City shall contract with an independent, arborist to (a) review plans to provide for maximum retention of trees and necessary additional tree protection measures; b) monitor project construction ; and c) recommend changes in the tree removal plan as necessary during construction. Mitigation measure 4.7-1(e) requires that all trees adjacent to project construction areas which are not removed will be avoided and protected according to specified procedures incorporated into all construction and/or demolition contracts. The Council finds that adoption of these measures will lessen the project's long and intermediate term impacts on trees and related wildlife habitat to less than significant levels, and will substantially lessen but will not avoid significant adverse short term impacts (0-10 years) to trees and related wildlife habitat within the City's jurisdiction. These measures provide for protection of as many trees as possible during project construction and replacement of all trees removed as a result of the project at a greater than 1-1 ratio. These mitigation measures will therefore eventually result in replacement of all trees and related habitat of equal or greater value. However, because it will take a number of years before replacement trees reach a level of maturity similar to those being removed, there will be a significant short-term and intermediate term decline in quality of trees and related habitat value at the project site. 4.7-2 Construction of the proposed projects would result in tree removals that could directly destroy nests, eggs and immature birds, and would remove future nesting habitat for birds, including sensitive species such as raptors and migrating songbirds. Mitigation measure 4.7-2(a) provides that in order to avoid the nesting season of raptors and sensitive songbirds, tree removals shall not take place between February 15 and June 30, unless otherwise determined by CDFG on a case -by -case basis. Mitigation measure 4.7-2(b) provides that if tree removal between January 1 and February 15 is required, a pre -construction survey shall be conducted to identify the presence, or lack 23 970702 lac 0031588 • S thereof, of nests of raptors. If nests are identified, CDFG shall be contacted and appropriate protocols for nest relocation shall be implemented. If relocation of occupied, viable nests is not feasible, construction shall be delayed and the tree left undisturbed until completion of nesting activity. Mitigation measure 4.7-2(c) requires implementation of mitigation measures 4.7 -1(a) -(f) and 4.7 -4(a) -(c) (tree replacement and riparian habitat replacement), discussed above. The Council finds that adoption of these measures will lessen the project's impacts on nesting birds to a less than significant level; These measures will avoid any direct destruction of nests and provide for eventual replacement or enhancement of all nesting habitat lost. While there will be a short term loss of nesting habitat for all bird species and short and intermediate term loss of nesting habitat for raptors, there are sufficient alternate nesting sites in the area that this impact will not have any significant adverse effect on overall nesting opportunities or on bird populations. 4.7-5 Construction -related noise and human activity for the proposed projects could create impacts to native wildlife species. Mitigation measure 4.7-5 prohibits construction activities within 50 -feet of riparian habitats along San Francisquito Creek during the nesting season (February 15 - June 30), unless otherwise determined on a case -by -case basis by the CDFG. The Council finds that adoption of this mitigation measure will lessen the project's potential noise and disturbance impacts on wildlife to a less than significant level. The adopted mitigation measure will ensure that construction activity does not disrupt mating or nesting activities of birds in this area. While some temporary disruption of activities of other species may occur during the allowed construction period, this temporary disturbance will not be sufficient to have any significant or long-term effects, such as loss of feeding areas or mating opportunities, on species or individuals within the area. 4.7-8 Ongoing operation of the proposed projects could adversely affect aquatic life, including sensitive animal species, in San Francisquito Creek, by increasing runoff and non -point source urban pollutant loads. Mitigation measure 4.7-8(a) requires implementation of mitigation measures 4.9 -1(a) -(c), discussed below. Mitigation measure 4.7-8(b) requires implementation mitigation measures 4.9-4(a) and (b), discussed below. The Council finds that adoption of these measures will lessen the identified potential impact on aquatic life in San Francisquito Creek to a less than significant level. The SIR concluded that the project, in conjunction with other Sand Hill Road Corridor 24 970702 lac 0031388 • projects, could result in increased runoff of sediments and contaminants into San Francisquito Creek due to increased extent of paved surfaces, landscaping and ground disturbances associated with the projects. The adopted mitigation measures require preparation and implementation of construction phase and post -construction storm water runoff management plans which will incorporate recognized best management practices to minimize siltation and runoff of contaminants from the project areas. These measures will reduce runoff of sediment or contaminants to levels which will not cause any detectable change in net water quality in San Francisquito Creek. 4.7-9 Operation of the proposed projects would increase human access resulting in direct impacts to sensitive animal species and disturbance and trampling damage to sensitive riparian habitat adjacent to San Francisquito Creek and to the Creek channel. Mitigation measure 4.7-9(a) requires that existing trails providing access to the riparian habitats along San Francisquito Creek be obliterated by dense barrier plantings of native riparian shrubs. A new trail will be designed for the length of the San Francisquito riparian corridor in the project area, located outside of riparian habitats and the drip lines of existing trees. Appropriate measures will be utilized to encourage exclusive use of this trail. Educational interpretive signs and displays shall be posted along this trail. View points shall be established in areas adjacent to the Creek where their siting will cause minimal damage to existing riparian vegetation. Direct public access to the Creek bank and channel shall not be permitted except over existing crossings and for access to these carefully sited view points. Mitigation measure 4.7-9(b) requires the project to be redesigned so that no new development occurs within the 100 -foot setback from the top of bank based on a 2:1 slope from the toe of the San Francisquito Creek channel. The Council finds that adoption of these mitigation measures will lessen the potential impacts of increased human intrusion of the San Francisquito Creek riparian area to a less than significant level. Due to the age of project residents, incidents of direct intrusion into San Francisquito Creek and its banks by residents are expected to be low to non-existent. While the project will also draw employees and visitors, including children, to the site and the project also provides for continued public access on trails close to San Francisquito Creek, mitigation measure 4.7-9(a) provides for substantial preventive measures to minimize direct human intrusion and resulting impacts to the riparian zone, and for restoration of existing damage, thus potentially resulting in a net beneficial impact to the riparian corridor. Mitigation measure 4.7-9(b) requires that a 100 foot buffer zone be maintained between the Creek and new development; the 100 foot buffer zone represents a buffer width generally accepted for biological mitigation purposes. This mitigation measure has been implemented through changes, including relocation of the pool and parking spaces 25 970702 lac 0031588 formerly located within the 100 foot buffer, incorporated into the project by the applicant prior to Council approval. 4.7-10 Implementation of the proposed projects, in conjunction with other proposed -projects in the area would result in incremental loss of trees and associated wildlife habitat. Mitigation measure 4.7-10(a) requires implementation of mitigation measures 4.7-1(a, b, c, and e), discussed above, for all Sand Hill Corridor projects. Mitigation measure 4.7-10(c) recommends that all planning jurisdictions in the project area, implement their respective tree protection and preservation ordinances. For those jurisdictions without such an ordinance, measures similar to those presented in mitigation measure 4.7-1 should be implemented on a project -by -project basis. The Council has adopted the recommended mitigation measures for the Stanford West Senior Housing project and other approved Sand Hill Corridor projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the cumulative loss of trees and associated wildlife habitat to a less than significant level. Adoption and implementation of these measures in conjunction with the Stanford West Apartments and Sand Hill Road Extension and Related Roadway Improvements projects will also reduce the combined cumulative impact of these projects to a less than significant level. .These measures generally provide for full replacement of trees lost due to implementation of the project, thus eliminating any significant cumulative impact. Adoption of equivalent mitigation measures for future development projects reviewed by the City is beyond the scope of approvals granted for the project. The Council finds, however, that City decision*nakers can and should adopt such measures in conjunction with any future projects which may result in cumulative loss of trees and associated wildlife habitat within the City. With respect to future implementation of the recommended measures by other jurisdictions in the area, the Council finds that implementation is within the jurisdiction and responsibility of the identified other agencies and that such measures can and should be adopted by such agencies. However, because the nature and extent of potential cumulative impacts from future development in the area are presently speculative and unknown, and the extent to which the recommended mitigation measures will be implemented by all responsible jurisdictions is also presently unknown and is beyond the control of the City, the Council cannot determine at this time the extent to which the recommended measures will lessen or avoid the potential cumulative impact, and therefore finds that the cumulative impact remains potentially significant. 26 970702 !ac 0031588 4.7-11 Construction of the proposed_ projects, in conjunction with other projects in the project area, would cumulatively result in tree removals that could directly destroy nests, eggs and immature birds, and would remove future nesting habitat for birds, including sensitive species such as raptors and migrating songbirds. Mitigation measure 4.7-11(a) requires implementation of mitigation measures 4.7 -2(a -c), discussed above, for the Sand Hill Corridor development projects. Mitigation measure 4.7-11(b) recommends that all planning jurisdictions in the project area implement measures similar to those presented in mitigation measure 4.7-2 on a project -by -project basis. The conditions of approval for the Stanford West Senior Housing project incorporate the applicable project -specific mitigation measures recommended in mitigation measure 4.7-11(a). The Council has also adopted the recommended project -specific mitigation measures as conditions of approval for the Stanford West Apartments and Sand Hill Road Extension and Related Roadway Improvements projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level. Adoption of these mitigation measures in conjunction with other approved projects will also reduce the combined cumulative impact of the projects to a less than significant level. These measures generally provide for avoidance of tree -cutting which may directly impact nesting activities and provide for full replacement of trees lost due to implementation of the project, thus eliminating any significant cumulative impact. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with future projects approved by the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that these agencies can and should implement such measures to the extent feasible. Because the nature and extent of the potential cumulative impact from future projects is presently entirely speculative and unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative visual impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 27 970702 lac 0031585 4.7-15 Ongoing operation of the proposed projects, in conjunction with similar projects within the same watershed, could - cause cumulative adverse affects on aquatic life, including sensitive animal species, in San Francisquito Creek, by increasing runoff and non -point source urban pollutant loads. Mitigation measure 4.7-15 requires implementation of mitigation measures 4.9 -7(a) -(c) for all Sand Hill Corridor projects. The conditions of approval, for the Stanford West Senior Housing .project.incorporate each of the applicable recommended project -specific mitigation measures. The Council has also adopted the recommended project -specific mitigation measures as conditions of approval for the other Sand Hill Corridorprojects approved concurrently with the project. The Council finds that adoption of" these recommended project -specific measures will lessen the project's contribution to the identified cumulative impact to a less than significant level. Adoption and implementation of these mitigation measures in conjunction with the other Sand Hill Corridor projects will also reduce the combined cumulative impact of these projects to a less than significant level. The adopted project -specific measures generally provide for preparation and compliance with detailed Storm. Water Pollutant .Prevention Plans which will include specific measures to prevent excessive sediment or pollution runoff which might result in significant adverse effects on aquatic life or habitat values in San Francisquito. Creek. Adoption of the recommended mitigation measures or equivalent measures for future development projects within the City is beyond the scope of approvals granted for the project; however, the. Council finds that such measures can and shoula be adopted in conjunction with any future projects approved by the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of the potential cumulative impact from future projects is presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative,impact resulting from increased runoff of sediment and pollutants into San Francisquito Creek. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 28 970702 lac 0031588 s • 4.7-16 Operation of the proposed projects, in conjunction with similar projects in or adjacent to the riparian corridor of San Francisquito Creek or its tributaries, would increase human access, cumulatively resulting in directimpacts to sensitive animal species and disturbance and trampling damage to sensitive riparian habitat. Mitigation measure 4:7-16(a) requires implementation of mitigation measures 4.7-9(a) and (b), discussed above for the Stanford West Apartments and Stanford West Senior Housing projects. Mitigation measure 4.7-16(b) recommends that all planning jurisdictions in the project area implement measures similar to those presented in mitigation measure 4.7-9 on a project -by -project basis. The Council has adopted each of the -project-specific mitigation measures referenced in mitigation measures 4.7-16(a) and 4.7-16,(b), in the conditionsi of approval for the Stanford West Apartments project and Stanford West Senior Housing project. The Council finds that adoption of the recommended project -specific measures will lessen the projects' contribution to potential cumulative impact on the San Francisquito Creek riparian corridor to a less than significant level. Adoption of -the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects within the City located near riparian habitat areas. With respect to future development projects -located outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative impacts from future development are presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative effects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the Council. 4.8 GEOLOGY. SOILS AND SEISMICITY 4.8-1 Expansive or weak soils could damage foundations by providing inadequate support. Mitigation measure 4.8-1(a) requires that site specific soil suitability analysis be conducted and soil stabilization procedures and foundation design criteria be adopted in accordance with engineering criteria where the existence of expansive and compressible soil conditions is known or suspected. 29 970702 lac 0031588 Mitigation measure 4.8-1(b) requires participation by the project's registered soil engineer as deemed necessary to oversee, verify, and report on soil engineering procedures and results. The BIR concludes that this impact is potentially, but not necessarily, significant, based on actual conditions encountered at the site. The Council finds that adoption of these mitigation `measures will lessen impacts related to potentially expansive or weak soils to a less than significant level. These measures provide for implementation of standard engineering procedures and criteria which will ensure construction of safe buildings and foundations. 4.8-2 The Stanford Sand Rill Road Corridor Projects area is subject to very strong seismically induced groundshaking which could threaten life and damage property. Mitigation measure 4.8-2(a) requires documented site -specific seismic -restraint criteria to be incorporated in the design of foundations and structures of the project which meet the minimum seismic -resistant design standards of CUBC Seismic Zone 4. Additional seismic -resistant earthwork and construction design criteria will be incorporated in the project where recommended by qualified experts. Roads, foundations. and underground utilities in fill or alluvium shall be designed to accommodate settlement or compaction produced by seismic forces. Mitigation measure 4.8-2(b) requires on -site participation by the project's registered geological or geotechnical engineering consultant, as deemed appropriate, to oversee, verify, and report on seismic -restraint procedures and results. Mitigation- measure 4.8-2(c) requires that an engineering geologist be contracted for third party review of all geologic, soils and engineering reports prepared for the proposed projects. The Council finds that adoption of these measures will lessen the impact of exposure to seismic events to a less than significant level. These measures implement standard engineering procedures and criteria for preventing major building failures and resulting injury or loss of life from any seismic event reasonably anticipated to occur in the project area. 4.8-4 Implementation of any combination of the projects, in conjunction with cumulative development within San Mateo and Santa Clara counties and the cities of Palo Alto and Menlo Park, would increase the number of people and structures subject to strong seismic groundsbaking and the subsequent risk of injury, loss of life and property damage. Mitigation measure 4.8-4(a) recommends that documented site -specific seismic -restraint criteria to be incorporated in the design of foundations and structures in the projects area, including the following (1) minimum seismic -resistant design standards shall conform to the CUBC Seismic Zone 4 Standards; (2) 30 970702 Lc 0031588 additional seismic -resistant earthwork and construction design criteria shall be incorporated as necessary, based on the site -specific engineering recommendations; (3) site preparation shall be supervised by geological -.or geotechnical consultants; (4) "as built" maps and a report shall be filed with the City, showing details of the site geology, the location and type of seismic -restraint facilities, and documenting satisfactory seismic performance for buildings, roads, foundations and underground utilities. Mitigation measure 4.8-4(b) recommends requiring on -site oversight, verification and reporting by registered geological or geotechnical engineering consultants where deemed appropriate by the City's Chief Building Official. The conditions of approval for the Stanford West Senior Housing project and for each of the other Sand Hill Corridor projects approved by the Council incorporate measures equivalent. to the project -Specific mitigation measures recommended. in mitigation measure 4.8-4(a). The Council 'finds that adoption of these project -specific measures will lessen the project's contribution to the identified cumulative impact to a less than significant level, and will also lessen the combined cumulative impact of the Sand Hill Corridor projects to a less than significant level. The adopted project -specific measures generally provide for incorporation of adequate seismic safety measures into all new construction as provided by mitigation -measures 4.8 -2(a) -(c). Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects approved by the City. With respect to cumulative impacts from future development outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that these agencies can and should implement such measures. Because the recommended mitigation measures rely in part upon compliance with existing seismic safety practices and standards, it is expected that other jurisdictions will implement the measures to a large extent. However, because the extent of the potential cumulative impact from future projects is presently unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures beyond current minimum standards is uncertain, the Council cannot fully determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen the potential cumulative impact associated with increased development in the seismically sensitive region around the projects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 31 9'70702 lac 0031588 BTD*QLOGY AND NAB QUALITY 4.9-1 Grading, excavation and construction activities could result in increased deposition of sediment and/or discharge of pollutants in the storm drainage system and San Francisquito Creek and adversely affect water quality. Mitigation measure 4.9-I(a) requires the applicant to prepare, retain and implement a Storm Water Pollution Prevention Plan ("SWPPP") which describes the site, erosion and sediment controls, means of material storage and waste disposal, implementation of approved local plans, post -construction control measures and maintenance responsibilities, and non -storm water management controls. The plan shall implement appropriate Best Management Practices ("BMPs") identified in the EIR. Mitigation measure 4.9-1(b) requires that the SWPPP shall be prepared by a qualified professional and approved by the City's Director of Public Works prior to issuance of a building permit. The SWPPP shall be implemented and inspected as part of the approval process for the grading plans for each project. Mitigation measure 4.9-1(c) requires that all construction contracts include the City's construction contract Pollution Prevention Language as part of the project specifications. The Council finds that adoption of these measures will lessen the project's potential sedimentation and contaminant impacts on San Francisquito Creek to a less than significant level. The adopted mitigation measures implement regulatory requirements and practices demonstrated to prevent excessive or damaging runoff of sediments and pollutants from development sites. Residual runoff of sediments and contaminants from construction areas, if any, will not occur in sufficient quantities to significantly degrade existing water quality. 4.9-4 Increased impervious surface and landscaping associated with development of the Proposed Projects could increase urban contaminants in surface runoff potentially reducing water quality in San Francisquito Creek. Mitigation measure 4.9-4(a) requires implementation of mitigation measures 4.9-1(a) through (c) for all approved Sand Hill Corridor projects. Mitigation measure 4.9-4(b) requires that the SWPPP shall include in the final project design appropriate BMPs selected by the City, consisting either of detailed measures identified in the EIR or equivalent measures. The Council finds that adoption of these measures will lessen the project's potential impacts on San Francisquito Creek to a less than significant level. These adopted mitigation measures require implementation of design features and operational practices which will reduce contamination of exposed surfaces at the project site 32 970702 lac 0031388 • . and trap or otherwise minimize runoff of such contaminants from the site. Residual contaminant runoff reaching San Francisquito Creek is not expected to constitute a sufficient addition to loads from existing development in the watershed to result in any measurable further deterioration of water quality. 4.9-5 Project construction activities in combination with other construction projects in the Watershed could cumulatively increase sediment and other construction -related pollutants in San Francisquito Creek and adversely affect water quality. Mitigation measure 4.9-5(a) recommends, that all area jurisdictions ensure that project applicants include EMPs in construction contracts implementing the requirements of NPDES Municipal Storm Water Permit #CAS029718. Mitigation measure 4.9-5(b) recommends that applicants for all area projects of five acres or more, be required to prepare a detailed SWPPP under the State General Construction Activity Storm Water Permit. Mitigation measure .4.9-5(c) requires implementation of mitigation measures 4.9-1(a) through (c) for all Sand Hill Corridor projects. The recommended mitigation measures or equivalent measures have been incorporated in the conditions of approval for the Stanford West Senior Housing project and for the other Sand Hill Corridor projects approved concurrently with the project. The Council finds that adoption of these project -specific measures will lessen the project's contribution to potential cumulative sedimentation and contaminant impacts associated with construction to a less than significant level and will also lessen the combined cumulative impact of the approved Sand Hill Corridor projects to a less than significant level. The adopted measures require implementation of control measures which will preclude significant sedimentation or contaminant impacts from the projects. Adoption of the recommended mitigation measures with respect to future development projects within the City's jurisdiction is beyond the scope of approvals granted for the project; however, the Council finds that the City can and should adopt and implement such measures for any future projects approved by the City which have a potential to adversely affect San Francisquito Creek. With respect to implementation of the recommended mitigation measures by jurisdictions other than the City, the Council finds that implementation of such measures is within the jurisdiction and responsibility of other public agencies and that the recommended measures can and should be implemented by these agencies. These measures are generally consistent with requirements imposed by state law. However, because the nature and extent of potential area -wide cumulative impacts from future development are presently unknown, and because the extent to which other agencies can and will implement the recommended measures beyond minimum standards is presently unknown, the Council cannot determine at this time the 33 9707021ac003LSU i extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will avoid potential cumulative impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the Council. 4.9-6 Increased impervious surfaces associated with development of the Stanford Sand Hill Road Corridor Projects and areas in the San Francisquito Creek Watershed could cumulatively increase surface runoff, potentially increasing the frequency and severity of existing downstream flooding. Mitigation measure 4.9-6 recommends that all jurisdictions regulating development in the San Francisquito Creek Watershed require that adequate drainage and flood control facilities be provided for existing and planned development, in compliance with applicable General Plan goals and policies and ordinances and iu coordination with Santa Clara Valley Water District (SCVWD) requirements. The Council finds that measures included in the project design and mitigation measures incorporated in the conditions of project approval, specifically use of the on -site retention basin on the neighboring Stanford West Apartments project site and mitigation measure 4.9-2, effectively implement the above recommended mitigation measure for the Stanford West Senior Housing project and will reduce the potential contribution of the project to cumulative flooding impacts to a less than significant level. Implementation of the recommended mitigation measure is beyond the scope of approvals granted for the project. However, the Council finds that the City can and will consider adoption and implementation of appropriate mitigation measures as future development projects are proposed and in accordance with its comprehensive plan and zoning ordinances. With respect to implementation of the recommended mitigation measure by other jurisdictions in the San Francisquito Creek watershed, the Council finds that jurisdiction and responsibility for implementation of the recommended mitigation measure is vested in other public agencies and that such agencies can and should adopt and implement appropriate mitigation programs. Because the extent of potential cumulative impacts from future watershed development is currently unknown, and because the Council cannot determine at this time the extent to which adequate mitigation measures will be implemented by other agencies, the.Council cannot presently determine whether the identified potential significant cumulative impact will be substantially lessened or avoided by the recommended mitigation. This cumulative impact therefore remains potentially significant. 34 970702 lac 0031588 • • 4.9-7 Increased impervious surface associated with development of the Stanford Sand Rill Road Corridor Projects and areas in the San Francisquito Creek Watershed could cumulatively increase urban contaminants in surface runoff potentially reducing water quality. Mitigation measure 4.9-7(a) recommends that all local jurisdictions ensure that future project applicants include BMPs as part of project design in accordance with San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) requirements. Mitigation measure 4.9-7(b) notes that it is within the jurisdiction of the SFBRWQCB to require that comprehensive SWPPPs and monitoring programs be implemented by all storm water dischargers associated with specified industrial activities, in compliance with the State's General Permits, and to require that such plans shall include BMPs or equally effective measures. Mitigation measure 4.9-7(c) requires implementation of mitigation measures 4.9-4(a) and (b) by all approved Sand Hill Corridor projects. The conditions of approval for the Stanford West Senior Housing project incorporate each of the recommended project -specific mitigation measures or equivalent measures to mitigate identified potential cumulative contaminant impacts to San Francisquito Creek. The Council finds that adoption of these recommended measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level. The recommended measures have also been adopted in connection with approval of the other approved Sand Hill Road Corridor projects, and will lessen the combined cumulative impact of the projects to a less than significant level. Adoption of the recommended Mitigation measures for future development is beyond the scope of approvals granted for the project. However, the Council finds that the City can and should 'adopt equivalent measures for all projects approved within its jurisdiction. With respect to impacts resulting from future development outside the City, jurisdiction and responsibility for implementation of recommended mitigation measures or equivalent measures is vested in other public agencies. The Council finds that these jurisdictions can and should implement such measures. However, because the nature and extent of potential cumulative impacts from future development are presently speculative and unknown, and the degree to which other jurisdictions will implement recommended mitigation measures is uncertain, the Council cannot determine at this time the extent to which the recommended measures will be implemented outside the City's boundaries and also cannot determine the extent to which these measures, if implemented, will lessen or avoid the identified potential cumulative impact. This cumulative impact therefore remains potentially significant. 35 970702 Inc 0031388 4.10 PUBLIC SAFETY _4.10-t Implementation of the proposed projects could expose constructi{.n workers to unidentified existing soil and/or groundwater contaminants at levels which could cause illness. Mitigation measure 4.10-1(a) requires that after demolition of the existing structures, an investigation shall be completed to detect and/or determine the extent of any contaminated soil or groundwater on the project site. Mitigation measure 4.10-1(c) requires that if investigation reveals evidence of chemical contamination, underground storage tanks, or other environmental impairments on the site, a remediation plan shall be prepared which will (1) specify measures to protect workers and the public; and (2) ensure clean up and disposal of contaminants and protect public health in accordance with federal, state, and local requirements. Work in the areas of potential hazard shall not proceed until the site remediation plan has been implemented. Appropriate agencies shall be notified as required. A site health and safety plan shall also be developed and implemented in compliance with OSHA requirements to ensure worker safety. The EIR concluded that although there are no known deposits or residues of unsafe contaminants on the project site, toxic materials and biological wastes were present on the site during its use as Stanford's Children's Hospital, and there remains a potential that such materials could be found in soils on the site. The Council finds that the adopted mitigation measures will reduce this potential impact to a less than significant level by ensuring that the site is fully investigated and evaluated for the possible presence of harmful substances, and indicated remediation efforts undertaken if contaminants are detected in amounts which might pose a hazard. 4.10-2 Implementation of the proposed projects could expose construction workers to asbestos containing materials presently located in buildings and other structures, resulting in adverse health effects. Mitigation measure 4.10-2(b) requires that all asbestos containing materials shall be removed and appropriately disposed of by a licensed asbestos abatement contractor prior to any building demolition. A site health and safety plan will be developed and implemented in compliance with OSHA requirements to ensure worker safety. The EIR concluded that due to the known presence of asbestos in some buildings which will be demolished on the site, there exists a potentially significant threat that workers could be exposed to asbestos during demolition. The Council finds that the adopted mitigation measure will lessen this potentially significant impact to a less than significant level by requiring that all asbestos containing materials be removed by qualified personnel 36 970702 lac 0031588 through accepted safe practices, and that any residual potential impacts be addressed through appropriate safety measures incorporated into a health and safety plan for project workers. 4.10-4 Implementation of the proposed projects could expose construction workers to electrical transformers and/or fluorescent light ballasts potentially containing PCBs, and subsequent adverse health effects. Mitigation measure 4.10-4(a) requires that all transformers on the project site that have not been tested for PCBs shall be tested prior to demolition and construction activities. Transformers found to contain PCBs will be removed and disposed of appropriately. Mitigation measure 4.10-4(c) requires that light ballasts in existing on -site facilities be tested for PCBs prior to demolition. Should PCBs be detected, all light ballasts shall be removed from the facility and appropriately disposed of by a licensed hazardous waste hauler per Title 22 requirements. Mitigation measure 4.10-4(e) requires that a site health and safety plan be developed in compliance with OSHA requirements to ensure worker safety prior to commencing removal and disposal of PCB -laden materials. The EIR concluded that two electrical transformers and florescent light fixtures on the property could contain PCBs which could have a significant impact on construction workers if accidentally released during demolition activities. The Council finds that the adopted mitigations measures will lessen this potentially significant impact to a less than significant level by providing for, testing and safe removal of all transformers and florescent fixtures containing PCBs prior to commencement of demolition and construction activities. 4.11 UTILITIES. ENERGY, AND INFRASTRUCTURE 4.11-3 The proposed projects could use water wastefully. Mitigation measure 4.11-3 requires that in order to reduce water consumption, the project design shall incorporate measures to maximize the efficient use of water and minimize total water consumption. Specific measures to be included are the following: All landscape designs shall incorporate and address the City Landscape Water Efficiency Standards. The project sites would be subject to an annual maximum water allowance for landscaping. The project applicant shall coordinate with the City of Palo Alto Utilities Department, Resource Management Division to determine other conservation related improvements that would apply to the projects. 37 970702 lac 0031588 • The EIR concluded that because final plans have not been completed by the applicant specifying how water, particularly for landscaping, would be efficiently used, there existed a potential that water could be used wastefully by the project. The Council finds that the adopted mitigation measure will lessen this potentially significant impact to insignificance by ensuring that final landscaping and construction plans meet current City Water Efficiency Standards and incorporate additional conservation measures if recommended by City staff. 4.11-4 Construction of the proposed improvements could disrupt existing water services. Mitigation measure 4.11-4 provides that prior to the start of construction of infrastructure, the project applicant shall provide a plan for review and approval to the City of Palo Alto Director of Utilities outlining the approach to be taken to minimize the impact to existing utilities and customers. The EIR determined that operations necessary to connect infrastructure associated with the project to existing service lines and facilities could result in potentially significant interruptions of utility services for existing users, specifically interruptions of water service (Impact 4-11-4), wastewater service- (Impact 4-11-11), electrical service (Impact 4-11-17) and gas service (Impact 4-11-24.) The Council finds that the adopted mitigation measure will lessen each of these potentially significant impacts to a less than significant level by requiring the applicant to submit and obtain approval of plans which will provide for completion of all utility connections for the project with the minimum necessary interruption of existing services. 4.11-7 Cumulative development could use water wastefully. Mitigation measure 4.11-7 provides that the City shall ensure that each new project approved within the City requiring ARB approval is required to be consistent with and implement the City policies and programs related to water conservation. The EIR concluded that existing City policies and programs are adequate to avoid cumulative wasteful use of water, and that a significant adverse impact had the potential to occur only if the City failed to continue to implement these policies and programs. The recommended mitigation measure provides that the City will continue to implement existing water conservation policies by making compliance a condition of ARB approval for all new projects. While implementation of this mitigation measure is beyond the scope of approvals granted for the Stanford West Senior Housing project, the Council finds that this mitigation measure can and should be implemented with respect to future projects and will lessen the identified potentially significant cumulative impact to insignificance. 38 970702 !ac 0031388 4.11.9 The proposed projects would require improvement of the existing 21 -inch wastewater line. Mitigation measure 4.11-9 requires that in the event that open -trench technology is used, the project applicant shall ensure that the new 24 -inch wastewater line is constructed coincident with, and placed in the right-of-way of, Palo Road, during Phase I of project construction, thereby avoiding the potential biological impacts and conflicts with future uses associated with the -alternative location of the line. The Council finds that adoption of this mitigation measure will lessen the potential significant adverse impacts associated with construction of a new 21" wastewater line to a less than significant level. This mitigation measure requires the applicant to either use technology which avoids trenching and resulting tree removal in the Stanford arboretum, or to relocate the route of the replacement -pipeline along existing right-of-way containing no significant environmental resources in order to avoid impacts to the arboretum. 4.11-11 Construction of the proposed improvements could disrupt existing wastewater services. Mitigation measure 4.11-11 requires implementation of mitigation measure 4.11-4, discussed above. See findings re mitigation measure 4.11-4. 4.11-13 Cumulative development could require major infrastructure improvements to the existing wastewater system. Mitigation measure 4.11-13(a) recommends that the City of Palo Alto Utilities Department ensure that developers responsible for construction of new wastewater lines coordinate with all other parties intending to utilize the line. Mitigation measure 4.11-13(b) recommends that sewer line capacity studies satisfactory to the City's Director of Utilities be conducted prior to initiating future cumulative development. Mitigation measure 4.11-13(c) recommends that all final designs for the sizing of new sewer mains shall be based on infiltration from a 20 -year storm and peak base wastewater flow. The EIR concluded that lack of coordinated planning for future development could result in failure to adequately size area wastewater lines, resulting in future need to again upgrade these lines to provide needed capacity. The recommended mitigation measures provide for full evaluation and correct sizing of mains prior to cumulative development. The Council finds that adoption of these measures will lessen the project's contribution to this potential cumulative impact to a less -than significant level. These mitigation measures will also lessen the overall potential cumulative impact to a less than significant level since 39 990702 lac 0031988 implementation of these measures will result in provision of adequate long-term capacity forr all reasonably foreseeable development. 4.11-17 Construction of the proposed improvements could disrupt existing electrical services. Mitigation measure 4.11-17 requires implementation of mitigation measure 4.11-4 for all Sand Hill Corridor projects. See findings re mitigation measure 4.11-4. 4.11-24 Construction of the proposed improvements could disrupt existing gas services. Mitigation measure 4.11-24 requires implementation of mitigation measure 4.11-4 for all Sand Hill Corridor projects. See findings re mitigation measure 4.11-4. 4.12 PUBLIC SERVICES AND SCHOOLS 4.12-2 The proposed projects would increase the number of emergency medical service calls to the PAFD. Mitigation measure 4.12-2(b) requires the applicant to pay a fair share for the cost of a new paramedic unit. This measure is implemented through Condition 45 of the project conditions of approval,which provides that the applicant shall pay $36,960 to the City as its share of the costs of a new paramedic van. The Council finds that adoption of this mitigation measure will lessen the project's potential impact on emergency medical services to a less than significant level. Condition 45 ensures that necessary funds will be made available when addition of new paramedic unit is determined necessary by the City to maintain current levels of service. The Council also finds that adoption of the alternative mitigation measure 4.12-2(a) identified in the EIR is not necessary to avoid potential significant adverse effects of the project on emergency medical services. Mitigation measure 4.12-2(a) proposes that the applicant provide private on -demand ambulance service to residents of the Stanford West Senior Housing project. The Council finds that increasing City-wide emergency medical response capabilities through a combination of applicant funds and other funds is a more desirable and cost-effective means of maintaining adequate emergency medical service levels for project residents and City residents generally than requiring the applicant to maintain special on -call ambulance services for project residents. 40 970 rot W0031588 4.12-4 Cumulative development would increase the annual number of fire suppression service calls to the PAFD. Mitigation measure 4.12-4 identifies three alternative means for offsetting cumulative increased demands on Palo Alto Fire Department (PAFD)resources. The conditions of approval for the project adopt the third of these alternate means, specifically: The City will provide additional resources to the PAFD through the City's General Fund from the increased tax revenues generated by the Sand Hill Corridor projects and other future cumulative projects. The Council finds that adoption of this measure will lessen the identified cumulative impact on fire suppression services to a less than significant level for each of the Sand Hill Corridor projects and future development. Cost and revenue projections for the approved projects indicate that increased tax revenues from the projects and other potential future development will be more than adequate to fund additional resources for the PAFD necessary to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased PAFD resources identified in EIR mitigation measure 4.12-4, specifically (1) fair share applicant funding of new PAFD personnel, and .(2) fair -share contributions from future projects, are not necessary based on current information to maintain adequate fire protection within the City and would result in imposing unnecessary special additional costs on new development. . 4.12-5 Cumulative development would increase the annual number of medical emergency service calls to the PAFD. Mitigation measure 4.12-5 identifies two alternative means of covering costs of additional emergency medical services should increases in current personnel and/or equipment prove necessary to meet future demand. The conditions of approval provide that the City shall adopt the second of these alternatives, specifically, the City shall provide additional medi-van resources to the PAFD if needed with general fund increases from tax revenues generated by the projects and other future cumulative projects. The Council has adopted the second of these mitigation alternatives for the Sand Hill Corridor projects. The Council finds that the adopted mitigation measure will lessen the identified potential cumulative impact on emergency medical services to a less than significant level. Cost and revenue projections indicate that increased tax revenues from the Sand Hill Corridor projects and other potential future development will be adequate to fund additional emergency medical resources as needed to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased emergency medical services identified in EIR mitigation measure 4.12-5, specifically that future development projects directly pay a fair share toward a medi-van unit or, is not necessary to 41 970702 ksc 0031588 maintain adequate level of emergency medical services based on current information. 4.12-6 Increased construction traffic from cumulative development could reduce PAFD response times. Mitigation measure 4.12-6 provides that as part of the project approval process, the City of Palo Alto Department of Planning and Community Environment shall ensure the following: All projects coordinate with the PAFD and Palo Alto Police Department (PAPD) to prepare an emergency response plan for the construction period that specifies alternate emergency response routes to the project site and vicinity which meet the Departments' response time goals; and The Emergency Response Plan for all Sand Hill Corridor projects will specify procedures to allow simultaneous construction without increasing emergency response times to an unacceptable level. The Council finds that adoption of this mitigation measure will lessen the project's potential impact on PAFD emergency response times to insignificance. This measure ensures that detailed plans will be developed and implemented to ensure that existing or adequate alternative response routes will be kept open at all timesto permit PAFD responses to all service areas within PAFD response time standards. 4.12-8 Design of the proposed projects could present security risks to occupants and police patrol personnel. Mitigation measure 4.12-8 provides that the applicant's lighting and landscaping plans will be reviewed with the PAPD to eliminate safety risks. The Council finds that adoption of this mitigation measure will lessen the identified potential safety impact to a less than significant level. This measure will ensure that qualified City police officers will review lighting and landscaping plans to so that the plans are designed to eliminate potential security hazards such as poorly lit areas along walkways. 4.12-10 Cumulative development would increase the annual number of police service calls to the PAPD. Mitigation measure 4.12-10 identifies three alternate means of funding additional police services to offset increased demand on Palo Alto Police Department resources. Condition 2.o of the project conditions of approval provides that the City shall adopt the second of these alternatives, specifically, the City shall fund additional PAPD resources from increased tax revenues generated by the projects and other future cumulative projects, 42 9'70702 lac 0031588 The Council finds that adoption of this measure will lessen the potential cumulative impact of the project and of new development generally on police services to a less than significant level. Cost and -revenue projections indicate that increased tax revenues from the Sand Hill Corridor projects and other potential future development will be adequate to fund additional emergency medical resources as needed to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased emergency medical services identified in EIR mitigation measure 4.12-5, specifically that future development projects directly pay a .fair share toward a medi-van unit or, is not necessary to maintain adequate level of emergency medical services based on current information. 4.12-11 Designs of cumulative development projects could present security risks to occupants and police patrol personnel. Mitigation measure 4.12-11 recommends that the City Department of Planning and Community Environment ensure that future project lighting and landscaping are reviewed with the PAPD to reduce safety risks.. The ARB shall provide final review and approval. This mitigation measure has been effectively implemented with respect to the Stanford West Senior Housing project through the adoption of mitigation measure 14.12-8. The Council finds that adoption of the measure will reduce the project's contribution to any potential significant cumulative impact to a less than significant level. This mitigation measure has also been adopted in conjunction with approval of the Stanford West Apartments project. Adoption of this mitigation measure as a policy governing review and approval of all future development within the City is beyond the scope of approvals granted for the Stanford West Senior Housing project. However, the Council finds that the recommended mitigation measure can and should be implemented in relation to. future development projects within the City. 4.12-12 Increased construction traffic from -cumulative development could increase PAPD response times. Mitigation measure 4.12-12 requires implementation of mitigation measure 4.12-6 by all approved Sand Hill Road Corridor Projects. - This mitigation measure has been implemented by adoption of mitigation measure 4.12-6 for the each of the approved Sand Hill Corridor projects. The Council finds that implementation of mitigation measure 4.12-6 will lessen the cumulative impact of construction of the projects on PAPD response times to a less than significant level. 43 970702 lac 0031388 • • 4.12-14 Cumulative development, including the proposed Stanford West Apartments Project, would cause 1C -12th grade enrollments to exceed PADSD school capacity of 916 students or 12 percent in year 2004-2005. The EIR proposed the adoption of mitigation measure 4.12-14 to mitigate this identified cumulative impact. Mitigation measure 4.12-14 recommends that the City adopt a policy that encourages all future developers to contribute their fair share over and above payment of the development fee to mitigate school impacts. The Stanford West Senior Housing project will not result in addition of any children to area schools, and thus will not cause or contribute to any cumulative impact on public schools regardless of the adoption of this suggested mitigation measure. However, the Council recognizes that cumulative impacts on public schools from future development are potentially significant, and further finds that these impacts would remain potentially significant whether or not the suggested mitigation measure is adopted as a policy of the City since contributions by developers would remain voluntary regardless of City encouragement. Adoption of a City policy of encouraging future developers to contribute school mitigation funds in excess of mandatory development fees is beyond the scope of approvals for the Stanford West Senior Housing project. However, the Council has taken substantial steps to encourage the project applicant to discuss and fund mutually acceptable mitigation measures with the school district in conjunction with the Stanford West Apartments project approved concurrently with this project,' and can and will continue to take similar steps to encourage voluntary additional contributions by developers of future projects with the goal of fully offsetting any impacts which cannot be mitigated through mandatory development fees and tax revenue increases associated with new development. 4.12-17 The operation of the proposed projects would increase solid waste generation in the City of Palo Alto requiring increased diversion to meet the goals of AB 939. Mitigation measure 4.12-17(a) requires that as a condition of project approval, the applicant shall prepare and obtain approval from the City Public Works Department of a landfill diversion management program that meets the diversion goals of the Source Reduction and Recycling Element (SRRE) and AB939. The program shall include specific provisions detailed in the EIR. Mitigation measure 4.12-17(b) recommends that the City require all new development projects to prepare operation recycling programs which will meet the AB939 diversion goal of 50 percent by 2000. The program shall include specific provisions detailed in the EIR. The Council finds that adoption of mitigation measure 4.12-17(a) will lessen the project's potential solid waste impacts to a less than significant level. This mitigation measure requires the applicant to develop, with City supervision, a plan which will 44 970702 lac 0031588 ensure that solid wastes from the project are processed in a manner which ensure compliance with the recycling goals of AB939. Adoption and enforcement of mitigation measure 4.12-17(a) will also implement mitigation measure 4.12-17(b) with respect to the project. Adoption of mitigation measure 4.12-17(b) as a policy governing review and approval of all future development within the City is beyond the scope of the decision and approvals granted for the Stanford West Senior Housing project. However, the Council finds that the proposed mitigation measure can and should adopted in relation to future development projects approved by the City. 4.12-18 The proposed projects would increase solid waste generation in the City of Palo Alto during construction requiring increased diversion to meet the goals of AB 939. Mitigation measure 4.12-18 requires the applicant to prepare and implement a construction recycling plan approved by the City Public Works Department. The plan shall include specific steps to achieve the City's short-term SRRE diversion goal of 30-40 percent through various specified measures. The Council finds that adoption of this measure will lessen the identified potential solid waste impact to a less than significant level. The approved recycling plan will ensure that provision is made for recovering all recyclable wastes generated during construction, thus avoiding unnecessary placement of recyclable materials in landfills. 4.12-19 Cumulative development anticipated by the City through Year 2010, including the proposed projects, would increase solid waste generation by 5.5 percent over 1995 levels to 155,650 tons per year based on the projected growth of population and employees. Mitigation measure 4.12-19(a) recommends that the City require significant new development projects to prepare construction recycling plans as part of the project approval process. The construction plan shall include specific steps to achieve the AB939 diversion goal of 50 percent by 2000 through various specified measures. Mitigation measure 4.12-19(b) recommends that the City require new development projects to prepare long-term operational recycling programs as part of project approval process. The programs should meet the AB939 diversion goal of 50 percent by 2000, and include various additional specified elements These mitigation measures have been effectively applied to the Stanford West Senior Housing project through the adoption of mitigation measures 4.12-17(a) and 4.12-18. The Council finds that adoption of those measures will reduce the project's contribution to potential cumulative solid waste impacts to a less than significant level. Adoption of mitigation measure 4.12-19(a) and 4.12-19(b) as policies governing review and approval of all future development within the City is beyond the scope of the decision and approvals granted for the Stanford West Senior Housing project. 45 970702 lac 0031588 However, the Council finds that adoption of the proposed mitigation measures or equivalent measures can and should be adopted in relation to future development projects approved by the City. 5.2 GROWTH INDUCING IMPACTS The EIR. concluded that the Stanford West Senior Housing project will have a significant growth inducing impact in that upgrading of the existing 21" sewer line serving the project area to the 24" line necessary to serve the project and the Stanford West Apartments and Stanford Shopping Center Expansion projects will remove an obstacle to growth of the Stanford Medical Center, which has announced tentative plans for expansion. The EIR does not identify any potential mitigation measures for this growth - inducing impact. The 24" sewer line will be constructed with the minimum size pipe available with sufficient capacity to ensure adequate service of the approved Sand Hill Corridor development projects. Since excess capacity will still be provided by this sewer line which could facilitate expansion of the Stanford Medical Center or other development, this impact is significant. The EIR concluded that the overall set of roadway improvements may serve to remove an obstacle to development of the contemplated 400,000 square foot expansion of the Stanford Medical Center. The traffic impacts of such development of the Medical Center as well as the impacts of cumulative development along the Sand Hill corridor were considered in the cumulative impacts analysis contained in the EIR. The EIR finds the impacts of such cumulative development within the Sand Hill corridor significant, as discussed elsewhere in these findings. 46 970702214c 0031588 PART II ALTERNATIVES TO THE PROJECT The Council has also considered the alternatives to the project analyzed in the EIR. Based on the following considerations, the Council has determined that all identified alternatives to the project are infeasible. The findings set forth below stating this Council's reasons for rejecting each alternative in favor of the project describe several separate grounds for rejecting each alternative, each of which this Council has determined constitutes an independent basis for this Council's decision to approve the project and to reject the proposed alternative. No Project - No Development This alternative assumes that no new development is authorized on the project site. The Council finds that this alternative is infeasible because it would preclude development of needed and desirable new housing and care facilities within the City for senior citizens. In addition, this alternative would reSuIt in continued lack of productive use of the property despite its existing developed condition. The Council believes that redevelopment of the property for beneficial uses such as that proposed by the applicant is desirable and preferable to locating new development on currently undeveloped land. No Project - No Action This alternative assumes that the existing buildings on the project site are reoccupied and returned to use as an active medical facility. Renovation and improvement of existing structures to meet current standards and needs of the medical use would probably take place under this alternative. The Council finds that this alternative is infeasible because it would not result in the development of needed and desirable new housing and care facilities for senior citizens. This alternative would also result in worsening of the current :jobs -housing balance within the City, in contravention of the City's important policy of attempting to achieve a more favorable balance of employment opportunities to housing opportunities in the City. In addition, while some short-term on -site impacts of this alternative could be less than the proposed project, this alternative would result in higher traffic and air quality impacts than the approved project. Implementation of this alternative is also highly uncertain in that there is presently no known persons or institution which has expressed an interest in occupying the site for medical uses. 75% Development Alternative This alternative consists of development of approximately 292 rather than 388 senior residential units on the site, and corresponding 25% reductions in the number of skilled nursing units 47 970702 lac 0031588 and assisted living units in the Health Care Center. This alternative would permit elimination of one building and modifications to others including elimination of wings and reduction in height by eliminating some upper stories. A proposed revised site plan implementing this alternative is included at p. 6.1-34 of the EIR; the Council also assumes that this alternative design could be modified to further reduce visual impacts if this alternative were selected for implementation. Due to reduced density and corresponding reduction in some building heights and building mass, this alternative would result in some incremental reduction of traffic, visual, land use and other impacts of the proposed project. However, some reduction of these impacts has also already been accomplished by revisions and mitigation measures adopted during the City's CEQA process. Because the alternative still involves substantial redevelopment of the site with large new buildings, the alternative will still result in significant and unavoidable land use, visual and traffic impacts at some intersections, although of lesser magnitude than the proposed project. The Council further finds that this alternative is infeasible because it would result in an unacceptable loss of needed housing units and special care facilities for senior citizens. Construction of all units in the proposed project is required to assist the City in meeting its anticipated need_for new housing units for the period 1996-2002, and to meet special needs identified in the federally required "Consolidated Plan for the City of Palo Alto (1995-2000)," which estimates 'a need for construction of up to 1,000 units of assisted living units and skilled nursing or 24 -hour care facilities for up to 950 individual senior citizens in the City. Studies performed by the Association of Bay Area Governments (ABAG),'summarized in the draft Housing Element Technical Document for the draft City of Palo Alto Comprehensive Plan now in preparation, project a need for construction of 1244 new housing units within the City for the period 1996-2002 to enable the City to satisfy its fair share of regional housing demands. Elderly households presently comprise about 25% of all households in the City. Elimination of approximately 96 residential units and a corresponding reduction in other residential care facilities provided by the project would substantially and unacceptably impair the City's ability to provide new quality housing for senior residents of the City and to meet the anticipated need for new assisted living units in the City and the region. Reduction of the project by approximately 96 units would also result in continued demand and resulting pressure for construction of new senior housing within the City or surrounding area. In addition, during public hearings the Council received substantial public testimony indicating that the project will provide attractive alternate housing for senior residents of the City who now occupy traditional single family homes, enabling these senior citizens to move from underutilized single family homes and make these homes available for purchase or rental by younger families. 48 970702 lac 0031588 Reduction of the number of units included in the project would also reduce this secondary housing benefit of the project. The marginal decreases in environmental impacts which would result from this alternative are not justified by the significant loss of senior housing units and reductions in senior care facilities which would result from the alternative. The Council believes that in the overall balancing of growth management and housing needs, efficient use of the project site for the maximum number of senior residential units which can be accommodated consistent with environmental and design constraints is preferable to reduced density development which will result in loss of needed senior residential units and care facilities. 50% Development Alternative This alternative consists of development of approximately 194 rather than 388 residential units on the site, and corresponding 501 reductions in the number of skilled nursing units and assisted living units in the Health Care Center. This alternative would permit elimination of buildings and modifications to others including elimination of wings and reduction in height by eliminating some upper stories. Due to reduced density and reduced building mass, this alternative would reduce many of the impacts of the project, including, traffic, visual, land use and other impacts but would not avoid or reduce to insignificance the significant land use, visual and traffic impacts associated with redevelopment of the site. The Council finds that this alternative is infeasible because it would result in an unacceptable loss of needed housing units and special care facilities for the City's senior citizens. Construction of all units in the proposed project is required to assist the City in meeting its anticipated need for new housing units for the period 1996-2002, and to meet special needs identified in the federally required "Consolidated Plan for the City of Palo Alto (1995-2000)," which estimates a need for construction of up to 1,000 units of assisted living units and skilled nursing or 24 -hour care facilities for up to 950 individual senior citizens in the City. Studies performed by the Association of Bay Area Governments (ABAG), summarized in the draft Housing Element Technical Document for the draft City of Palo Alto Comprehensive Plan now in preparation, project a need for construction of 1244 new housing units within the City for the period 1996-2002 to enable the City to satisfy its fair share of regional housing demands. Elderly households presently comprise about 25% of all households in the City. Elimination of approximately 192 residential units and a 50% reduction in other senior care facilities provided by the project would substantially and unacceptably impair the City's ability to provide new quality housing for senior residents of the City and to meet the anticipated need for new assisted living units in the City and the region. 49 974702 lac 0031588 • Reduction of the project by approximately 192 units would also result in continued demand and resulting pressure for construction of new senior housing within the City or surrounding area. In addition, during public hearings the Council received substantial public testimony indicating that the project will provide attractive alternate housing for senior residents of the City who now occupy traditional single family homes, enabling these senior citizens to move from underutilized single family homes and make these homes available for purchase or rental by younger families. Reduction of the number of units included in the project would also reduce this secondary housing benefit of the project. The decreases in environmental impacts which would result from this alternative are not justified by the significant loss of senior housing units and reductions in senior care facilities which would result from the alternative. The Council believes that in the overall balancing of growth management and housing needs, efficient use of the project site for the maximum number of senior residential units which can be accommodated consistent with environmental and design constraints is preferable to reduced density development which will result in loss of needed senior residential units and care facilities and continued demand for construction of such facilities at other locations in the area. Campus West Alternative Site The Campus West alternative site is an undeveloped parcel owned by Stanford south of Sand Hill Road and across from the Oak creek Apartments which border the Stanford West Apartments site. The Campus West site is currently outside the jurisdiction of the City and entirely within the territory of the County of Santa Clara. The EIR evaluated relocation of both the Stanford West Apartments and Stanford West Senior Housing projects to this site, and concluded that both could be substantially accommodated with extensive redesign and a probable increase in building heights. The EIR also noted that some reduction could be made in the total number of units approved on the West Campus site to better accommodate site constraints and provide for mitigation of impacts. However, for purposes of considering this alternative, the Council has assumed that all senior residential units and all other senior care facilities currently proposed as part of the Stanford West Senior Housing project could be accommodated on the Campus West site with acceptable environmental effects. In considering this alternative, the Council has also considered the possibility of partially adopting this alternative by relocating only the Stanford West Senior Housing project to the Campus West site. Development of the Stanford West Senior Housing only on the site would provide maximum flexibility to design and locate the project to minimize adverse environmental effects, and could limit loss of open space on the Campus West site to less than half of the site. The Council, however, finds that development of the Stanford West Senior Housing on the West Campus site, either alone or in conjunction with development of the Stanford West Apartments project, is infeasible and should be rejected for the following reasons: 50 970702 (ac 0031588 • 1. The alternative is inconsistent with existing Santa Clara County and City of Palo Alto land use designations and policies for use of the West Campus site. Use of the property for housing unrelated to academic needs is also inconsistent with Stanford's long range master plan for use of campus lands. 2. Implementation of this alternative is uncertain and would, even if implemented, involve substantial delay in construction of new senior housing and care facilities. 3. On balance, the alternative is not environmentally superior to the proposed project in that it would result in loss of existing open space and related grassland and oak habitat rather than reuse of an existing developed site. The Campus West site is presently designated in the Santa Clara County general plan and Stanford's general use permit and in Stanford's land use plans as "Major Educational and Institutional Uses." Long term development plans for this property by Stanford contemplate development of educational, research or other facilities directly related to the University's academic, mission rather than non -University housing or income-prciucing uses. Because development of housing, particularly housing not intended for academic use, on the Campus West site is inconsistent with Stanford's existing long-term plans, it is uncertain that Stanford would attempt to implement this alternative if requested by the City. Failure by Stanford to pursue this alternative would result in loss of all new senior housing units and related senior care facilities associated with the project. If Stanford did elect to pursue this alternative, implementation would require submittal of an entirely new application and commencement of a new approval process either by the County of Santa Clara, or by the City if annexation is proposed as part of the project. Due to the size of the project and potential environmental impacts of development at this alternate location, the approval process would necessarily involve a complete redesign of the project and a new environmental impact report, resulting in substantial delays in construction of any actual new senior housing and care facilities. Because many of the potential impacts of this alternative, including loss of open space, visual. impacts, increase in area traffic and changes in character of the area and loss of habitat area are similar in nature to the impacts of the approved project, it is probable that implementation of the alternative would also be subject to public opposition greater than experienced by the approved project. Under existing agreements between Stanford, the County of Santa Clara and the City, development of senior housing on this site would include annexation of the property to the City. While the City would have primary approval authority over any such development proposal, the City cannot prejudge its ultimate decision on any such application, and implementation of the alternative is therefore uncertain even if annexation is proposed. Because there is already a substantial and 51 970702 tag 0031588 • • immediate need for additional housing and for new senior care facilities in the City, the Council believes that the additional delay and uncertainty of implementation of this alternative are unacceptable and further render the alternative infeasible. This alternative would also have important adverse environmental impacts which the Council finds are, on balance, worse than those of the proposed project. Specifically, this alternative would result in substantial loss of grassland and oak savannah habitat area, loss of open space and related land use and visual impacts along the Sand Hill Road Corridor. While relocation of the project to the Campus West site would also avoid or reduce some of the impacts associated with redevelopment of the former Children's Hospital site, these impacts have in all cases been mitigated to levels this Council finds acceptable, and which the Council finds are more acceptable than the substantial impacts which would result from development of the Campus West site. Ouarry Road/El Camino Alternative Site The Quarry Road/E1 Camino site consists of approximately 6 acres of undeveloped land owned by Stanford at the intersections of El Camino Real and Quarry Road. The site is presently located within the jurisdiction of the County of Santa Clara; however, for purposes of considering this alternative, the Council assumes that the site would be annexed to the City as part of the approval process for the alternative. The Council finds that development of the Stanford West Senior Housing at this alternative site is infeasible and therefore rejects the alternative on the following grounds: 1) Due to the smaller amount of land available at this site, development at this site would result in unacceptable loss of senior housing units; 2) The site is not as well suited for development of senior housing as is the proposed site, and would result in incompatibility with surrounding uses; 3) Implementation of this alternative is uncertain and speculative and would, even if implemented, involve substantial delay in construction of new senior housing and care facilities; and 4) This alternative would not be sufficiently environmentally preferable to the proposed project to justify its adoption rather than the proposed site. Due to the smaller (6 acre) size of this alternative site, the SIR estimates that approximately 225 senior housing units, or about 58% of the proposed project overall, could be constructed on the site after making reasonable allowances for setbacks, landscaping and parking. A maximum of 240 residential units could be allowed at residential zoning density of 40 units per acre. Implementation of this alternative would thus result in the loss of 144 or more 52 970702 lac 0031388 senior residential use from the project. This loss of senior housing units is unacceptable and renders the project infeasible for reasons previously stated in reference to the 75% and 50% reduced density alternatives. The site is also not as well suited for development of senior housing and care facilities as is the proposed site. The site is presently surrounded on three sides by roadways and major commercial and institutional uses. Due to the relatively small size of the parcel, noise and other impacts from these adjoining uses could not be adequately mitigated through buffer zones and landscaping to meet the needs of project senior residents. Because of the necessary height and bulk of buildings, the senior housing project would also be visually incompatible with existing character of the surrounding area. Implementation of this alternative would also require preparation and review of entirely new development plans, including the probable preparation of a new environmental impact report. Under current agreements between Stanford, the County of Santa Clara and the City the site would be annexed to the City prior to development, and the City would have primary approval authority over any such development proposal. The City Council cannot prejudge the ultimate decision on any such development proposal, and there are substantial reasons, discussed above, to believe that such a proposal would not ultimately be approved. Because there is already a substantial and immediate need for additional housing and for new senior care facilities in the City, the Council believes that the additional delay and uncertainty of implementation of this alternative further renders the alternative infeasible. This alternative would also not result in substantial environmental advantages over the approved project that are so substantial as to justify approval of this alternative instead of the proposed project. Development of the Quarry Road site would result in loss of existing open space, as well as trees which currently occupy the site, and would also result in substantial visual and land use impacts due to the change in character of the site. While relocation of the project to the Quarry Road site would also avoid some of the -impacts associated with redevelopment of the former Children's Hospital site, the mitigation measures and conditions of approval adopted in conjunction with the approved project mitigate these same impacts to acceptable levels. The Council finds that given the loss of open space and visual and land use impacts which would result from development on the Quarry Road site, the redevelopment of the former Children's Hospital Site for the project will result in less environmental impacts overall than development at the Quarry Road site. No Housing Alternative The EIR also examined a "no -housing" alternative which would have consisted of approving 160,000 square feet of new commercial space for the Stanford Shopping Center and approving the Sand Hill Road Extension and Related Roadway Improvements project while 53 970702 lac 0031588 i • • denying approval for the proposed Stanford West Apartments and Stanford West Senior Housing projects. The primary purpose of this EIR alternative was to examine the effects on the area transportation system of approving only the proposed roadway improvements and proposed shopping center expansion elements of the Sand Hill Corridor projects. With respect to the Stanford West Senior Housing project, the Council finds that the alternative is infeasible for the reasons previously stated in reference to the No Project -No Development alternative. Housing With Limited Shopping Center Development The EIR also examined a "housing with limited shopping center expansion" alternative consisting of (1) approval of the Stanford West Apartments and Stanford West Senior Housing; (2) construction of 49,000 square feet of new Stanford Shopping Center space only; (3) without any of the roadway improvements proposed in the Sand Hill Road Extension and Related Roadway Improvements project. The Council does not consider this alternative to be an alternative to the Stanford West Senior Housing project. This alternative was evaluated in the EIR to examine the effects on the area transportation system of approving only residential development and limited shopping expansion, without major area roadway improvements. This alternative is discussed in the findings relating to the Stanford Shopping Center project. 54 970702 l c 00315U EXHIBIT D STANFORD SHOPPING CENTER EXPANSION PROJECT COUNCIL FINDINGS CONCERNING MITIGATION OF ENVIRONMENTAL IMPACTS AND CONSIDERATION OF ALTERNATIVES The City Council of the City of Palo Alto ("Council") has read and considered the Final Environmental Impact Report ("EIR") prepared for the Stanford Shopping Center Expansion project. The EIR has been prepared for five projects including the Stanford West Apartments, Stanford West Senior Housing, Stanford Shopping Center Expansion, Sand Hill Road Extension and Related Roadway Improvements ("SHRE/RRI") projects, referred to collectively herein as the "Sand Hill Corridor projects," and the Pasteur Drive Parcel Annexation project. These projects are described in Chapter 3 of the EIR, and include, as approved by the Council, the changes and revisions described in Chapter 11 and in the "Final Summary of Project Changes" made a part of the Final EIR by the certifying .resolution. Pursuant to Section 21081(a) of the Public Resources Code, the Council has considered each environmental impact of the Stanford Shopping Center Expansion project identified in the EIR, and each of the mitigation measures and project alternatives evaluated in the EIR. The Council's detailed findings for each significant environmental impact or potentially significant environmental impact identified in the EIR are set forth below. Each significant or potentially significant environmental impact identified in the EIR is listed in bold. Those mitigation measures adopted or partially adopted by the Council are also numbered in bold. The Council's reasons for rejection or partial rejection of certain mitigation measures and reasons for selection among alternative potential mitigation measures are described where appropriate. The Council's reasons for rejecting specific alternatives to the project identified in the EIR are stated in Part II of these findings. 1 970702 lac 0031589 PART I CHANGES AND MITIGATION MEASURES ADOPTED TO REDUCE IMPACTS 4.1 LAND US8 4.1-5 Implementation of the proposed projects, in conjunction with cumulative development within the Sand Hill Road Corridor, would result in a change in character in the area. The EIR concludes that there are no feasible mitigation measures available which will substantially reduce the identified significant land use impact and that this impact is therefore unavoidable. The approved Stanford Shopping Center Expansion project itself will have relatively little adverse effect on the existing character of the Sand Hill Corridor because the site is currently extensively developed. The conditions for approval of the project and other approved Sand Hill Corridor projects incorporate a number of mitigation measures which will lessen the overall severity of these impacts by reducing visual impacts, providing for replacement and restoration of trees and habitat affected by the project of trees, enhancing opportunities for pedestrian and bicycle travel in the corridor and mitigating potential noise impacts on residences along Sand Hill Road. The measures adopted in conjunction with approval of the Stanford Shopping Center Expansion project are discussed in greater detail in the detailed findings set forth below regarding mitigation of visual, transportation, biological and noise impacts of the project. Changes have also been incorporated into the project, including relocation of proposed parking structures to the south side of the Stanford Shopping Center and reduction of the project to construction of 80,000 sq. ft. of commercial space which will further reduce the project's contribution to the identified cumulative land use impact. However, the Council recognizes that the cumulative effect of changes to the existing character of the Sand Hill corridor resulting from approval of the Stanford West Apartments, Stanford West Senior Housing and Sand Hill Road Extension and Related Roadway Improvements projects concurrently with the project are significant. 4.2 VISUAL QUALITY/LIGHT AND GLARE 4.2-1 The proposed projects would result in major visual changes within the Sand Hill Road corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-1(g), as modified by condition 2.g, requires that the density and frequency of street tree planting in the center medians and southern road edge of Sand Hill Road shall be extended to run continuously along the Sand Hill Road Extension, to achieve eventual canopy closure between trees. 2 970702 lac 0031589 • • Mitigation measure 4.2-1(1) provides that the Proposed Parking Structures shall be consolidated on the Quarry Road side of the Shopping Center to supply the same number of spaces. The Council finds that implementation of these measures will lessen the project's visual impacts within the Sand Hill Road corridor to a less than significant level. The adopted measures provide for relocation of the proposed parking structure to the Quarry Road side of the Stanford Shopping Center, thus completely eliminating the visual impacts of this structure on views from Sand Hill Road. This change has been voluntarily incorporated into the project design by the applicant as discussed in Chapter 13 of the Final EIR, and is further implemented through conditions 2, 4, 5A, 11, and 13 of the project conditions of approval. The amount of new commercial development included in the project has also been reduced to 80,000 square feet, which will result in a commensurate reduction in the amount of parking. While some new construction will occur within view of Sand Hill Road, this development will be visually compatible with existing development on the site and is not of sufficient mass or proximity to Sand Hill Road to cause a significant adverse visual impact. Any remaining potential visual impact will be further offset by landscaping along the medians and southern edge of Sand Hill Road which will substantially screen the development from view. The relocation of the single new parking structure to Quarry road will also eliminate the need for implementation of mitigation measure 4.2-1(k). 4.2-4 Proposed new project features including four-story Senior Housing buildings, the proposed parking structure at Quarry Road, and various retail buildings along Arboretum Road would alter the character of the existing setting in the vicinity of Arboretum Road and Quarry Road, with potential adverse effects on viewers there and in the Shopping Center. Mitigation measure 4.2-4(a) requires that design guidelines or other mechanisms approved by the Palo Alto Architectural Review Board should be applied to help ensure compatibility of the new streetscape and avoid design incompatibilities among prominently placed proposed retail buildings on Arboretum Road. Mitigation measure 4.2-4(d) provides that existing landscaping removed for the widening of Quarry Road will be replaced with plantings of trees and shrubs of sufficient density and height to screen both the Hoover Pavilion parking lot and adjacent substation from casual view of travelers on Quarry Road. Conditions 4 and 5 of the project conditions approval impose further design requirements, including further review by the City's Architectural Review Board to reduce the visual length and potential monolithic quality. These conditions have been adopted in place of mitigation measures 4.2-4(b) and 4.2-4(c). Condition 4 requires that the new parking structure shall be limited to a maximum height of 24 feet 10 inches to the top of the railing, to accommodate approximately 1535 cars. The existing 3 970702 lac 0031589 • • parking structure at the corner of Quarry Road and Arboretum Road will remain. The Council finds that adoption of these measures will lessen the project's visual impacts on the Arboretum Road/Quarry Road area to a less than significant level. While the project will result in additional development in this area and addition of a large parking structure, these project elements are not incompatible with existing development in the area. Appropriate landscaping will be utilized to soften and screen views. The adopted mitigation measures will ensure that available architectural techniques are utilized to minimize visual impacts and achieve overall compatibility between new construction and existing development in the area. 4.2-8 Visual disturbance from construction of the proposed projects could have temporary adverse visual impacts. Mitigation measure 4.2-8 requires that on -site staging and storage of construction equipment and materials should be minimized to reduce visual disturbance during construction. Equipment and material storage that does occur on -site should be visually screened. Graded areas should be watered regularly to minimize fugitive dust. Construction should be staged and scheduled to minimize the duration of disturbance in each affected viewshed. The Council finds that adoption of this mitigation measure will lessen the adverse visual impact of project construction, but will not reduce this impact to a less than significant level. The adopted mitigation measure will limit the duration and visibility of construction equipment and grading activities on the site, but will not eliminate the significant visual impact necessarily associated with major construction activities on the site. This impact therefore remains significant. 4.2-9 The proposed projects, in conjunction with cumulative development in the Sand Hill Road Corridor, could adversely affect the visual character of the corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-9 recommends that mitigation measures 4.2-1(a-1) be implemented for all the Sand Hill Road Corridor Projects. The project specific mitigation measures recommended in 4.2-9 for the Stanford Shopping Center Expansion have been adopted or effectively implemented by changes in the proposed project. The Council finds that adoption of these changes and mitigation measures will lessen the project's contribution to cumulative visual impacts to the Sand Hill corridor to a less than significant level. The additional project -specific mitigation measures recommended in mitigation measure 4.2-9 have been adopted, partially adopted, or rejected as stated in the findings for the 4 970702 lac 0031589 S Stanford West Apartments, Stanford West Senior Housing, .and Sand Hill Road Extension and Related Roadway Improvements projects. To the extent these measures have been adopted, they collectively will reduce but not eliminate the significant adverse cumulative visual impacts of the Sand Hill Corridor projects. This cumulative impact therefore remains significant. The Council recognizes that future development, to the extent allowed in the Sand Hill Corridor, will continue to add to the significant cumulative visual impacts associated with the approved projects. 4.2-12 The combined visual effect of proposed projects could adversely alter views within the El Camino Real viewshed. Mitigation measure 4.2-12 requires implementation of mitigation measures 4.2 -6(a -c). Mitigation measure 4.2-6(a) requires the applicant to prepare and implement design guidelines or controls for development of the retail structure at Quarry Road and El Camino Real to ensure compatibility with the area, subject to approval by the Palo Alto Architectural Review Board and Planning Commission. An alternative, which the Council has rejected, provides that the applicant may remove this structure from the site plan, relocating the square footage to other portions of the Shopping Center if feasible. Mitigation measure 4.2-6(b) requires the intersection of Quarry Road and El Camino Real to be redesigned to improve overall visual quality and pedestrian operations, including the following specific changes: (a) reduce the width and number of proposed lanes of El Camino Real; (b) include a minimum 10 -foot wide landscaped median and pedestrian refuge area in the center median of El Camino Real. Mitigation measure 4.2-6(c) provides that if mitigation measures 4.2-1(1), 4.2-5(b) and 4.2-6(b) are all adopted, the applicant shall be required to conduct a detailed study of traffic progression and traffic signal coordination on El Camino Road and prepare a signal coordination plan. The plan shall encompass signalized intersections on El Camino Real from Embarcadero Road to the proposed Sand Hill Road extension and must demonstrate that northbound left -turn queues at both the Quarry/E1 Camino Real and Sand Hill Road/E1 Camino Real intersection will not obstruct northbound through lanes. Mitigation measure 4.2-6(d) requires that large evergreen shrubs or evergreen trees be incorporated in the final landscape plan along the north edge of Quarry Road and other areas near the corner of El Camino Real, in order to maintain some visual screening of the parking lot areas from the new intersection during winter months. 5 970702 lac 003 i 589 • • These measures will be implemented through the conditions of approval of the SHRE/RRI project and Stanford Shopping Center Expansion project as appropriate. The Council finds that adoption of these mitigation measures will lessen the project's contribution to cumulative visual impacts on the El Camino Real viewshed to a less than significant level and will also lessen the combined cumulative effect of the project and the SHRE/RRI project to a less than significant level. These measures provide for modifications to the proposed projects to diminish the extent of visual changes in the affected project area and for further design review and improvement to ensure compatibility with the existing visual character of the area. Mitigation measure 4.2-6(c) is designed to offset any adverse traffic impacts which will result from implementation of these measures. With respect to mitigation measure 4.2-6(a), the Planning Commission considered the alternative of eliminating the proposed retail building near Quarry Road and El Camino and recommended against this alternative. The Council also finds that relocation of this building is unnecessary and would defeat one of the design objectives of the Shopping Center expansion plans, specifically to provide an improved transition from the central shopping area of the Stanford Shopping Center to El Camino Real and adjoining portions of the City. The project conditions of approval implement the alternate form of mitigation proposed in mitigation measure 4.2-6(a). The Council finds that this measure will mitigate the adverse impact associated with the original design of the outlying building to a less than significant level. 4.2-13 The proposed projects, in conjunction with cumulative development, could generate light and glare from buildings and roadways that could have adverse effects on nearby residents and on -coming drivers along Sand Hill Road. Mitigation measure 4.2-13 provides that interior and exterior light sources associated with all of the approved Sand Hill Corridor projects shall be shielded or directed in such a manner as to prevent visibility of the light sources and to eliminate light spillover beyond the perimeter of the proposed project. Specific. measures recommended in accordance with section 18.64.030 of the Palo Alto Municipal Code include the following: (a) Exterior light fixtures on the housing buildings should be mounted no higher than 15 feet at the rear of the buildings. (b) Lighting of the building exterior and parking lot should be of the lowest intensity and energy use adequate for its purpose. (c) Unnecessary continued illumination, such as illuminated signs, should be avoided. (d) Timing devices should be considered for exterior and interior lights in order to minimize light glare at night without jeopardizing security. 6 970702 lac 0031589 • • The Council finds that adoption of this measure will lessen the project's contribution to potential cumulative light and glare impacts to insignificance. The adopted mitigation measure will have the effect of eliminating substantial spillover of light from the project site and will therefore reduce any potential cumulative impact to insignificance. This measure has also been incorporated into the conditions of approval for other approved Sand Hill Corridor development projects and will therefore eliminate any potential significant cumulative effect by confining the impacts of each project to its own location. 4.3 CULTURAL RESOURCES 4.3-1 Implementation of the proposed projects would result in damaging effects on important historic and/or prehistoric archaeological resources. Mitigation measure 4.3-1(g) provides that if previously unidentified cultural resources are discovered during construction, work shall cease in the immediate area until. qualified archaeologists assess the significance of the resources and make mitigation recommendations (e.g., manual excavation of the immediate area), if warranted. Mitigation measure 4.3-1(h) requires the applicant and contractors to comply with the requirements of Section 7050.5(b) of the California Health and Safety Code if Native American burials or other possible Native American human remains are located during construction. This code section requires that a Native American Most Likely Descendant (determined in consultation with the Native American Heritage Commission) be notified within 24 hours and appropriate provisions made for appropriate reburial. This and related sections of the Public Resources Code also provide that remains shall be protected from further construction work or vandalism. Mitigation measure 4.3-1(k) provides that project construction activities shall be subject to archaeological monitoring where ground disturbance will exceed 24 inches below existing grade. Monitoring may be conducted on an intermittent basis only where, in the opinion of the applicant's archaeologist and the City's archaeologist, soils are culturally sterile. Construction personnel shall be required to contact the applicant's archaeologist in the event that suspected cultural resources are uncovered in the absence of a monitor. The Council finds that adoption of these mitigation measures will lessen the project's potential impact on archaeological resources to a less than significant level. No significant archaeological resources are known to exist on the project site nor is there a high probability of encountering any such resources given the distance from San Prancisquito Creek and developed nature of the site. The EIR nevertheless concluded that potentially significant impacts could occur if important archaeological resources were unexpectedly encountered on the site. The adopted 7 970702 lac 0031589 • • mitigation measures provide for monitoring of construction activities to ensure that any important archaeological resources encountered will be identified, protected and removed and preserved for further study in accordance with accepted scientific standards, ensuring no loss of scientific or historical value of the resources. The adopted measures also ensure that proper respect will be afforded any burials and any other culturally important Native American remnants which might be impacted by the project. 4.3-6 The proposed projects, in conjunction with other cumulative development projects in the San Francisquito Creek drainage, could result in damage or destruction of important prehistoric and historic cultural resources. Mitigation measure 4.3-6 recommends that all planning jurisdictions within the San Francisquito Creek drainage implement cultural resource testing and data recovery measures, similar to those described in mitigation measure 4.3-1 for projects involving development of sensitive cultural resource sites. The Council has adopted the recommended project -specific mitigation measures for Stanford Shopping Center Expansion project and all other approved Sand Hill Corridor projects. The Council finds that adoption of these mitigation measures will lessen the project's potential contribution to the identified cumulative impacts to a less than significant level and will also lessen the cumulative impact of the Sand Hill Corridor projects collectively to a less than significant level. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be considered in conjunction with any future projects within the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative impact from future projects on archaeological resources is presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative visual impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 8 970702 lac 0031589 4.4 TRANSPORTATION 4.4-7 Development of the proposed projects could degrade the level of service of study area intersections, and contribute to increased intersection delay. The EIR concluded that changes and increases in traffic patterns resulting from the Sand Hill Road Corridor projects collectively will result in significant adverse changes in traffic conditions at a total of seven area intersections, specifically: Arboretum Road/Galvez Street El Camino Real/Page Mill Road El Camino Real/Ravenswood Avenue El Camino Real/Valparaiso Avenue/Glenwood Avenue Junipero Serra Blvd./Alpine Road/Santa Cruz Avenue Middlefield Road/Willow Road Sand Hill Road/Santa Cruz Avenue The approved Stanford Shopping Center Expansion project alone, however, would have significant adverse impacts on traffic levels at only four area intersections, specifically: Arboretum Road/Galvez Street El Camino Real/Page Mill Road Middlefield Road/Willow Road Sand Hill Road/Santa Cruz Avenue The conditions of approval nevertheless require the applicant to contribute to all of the following mitigation measures. Arboretum Road/Galvez Street: Mitigation measure 4.4-7(a) requires the applicant to install a traffic signal or other appropriate traffic control device(s) at the intersection of Arboretum Road/Galvez Street, and pay the full cost of these improvements. This measure shall be implemented when the intersection satisfies appropriate signal warrants as determined by the Chief Transportation Official. In the event that the City and the applicant determine that use of a traffic circle or "roundabout" will provide for the same or better LOS and safety as a traffic signal, the traffic circle may be constructed at the applicant's expense instead of a traffic signals or other traditional traffic control device(s). El Camino Real/Page Mill Road: Mitigation measure 4.4-7(b) requires the applicant to contribute a fair share of the costs of the following planned improvements: Add a southbound right turn lane; Add a westbound right turn lane; Add a northbound right turn lane; and Extend the westbound left turn lane by 100 feet. 9 970702 Lac 0031589 • • These measures should be implemented when the intersection approaches LOS F, as evaluated through periodic monitoring to be carried out by the applicant on behalf the City. Sand Hill Road/San Cruz Avenue: Mitigation measure 4.4-7(c) requires the applicant to pay a fair share of the costs of following improvements to the following improvements to the Sand Hill Road/Santa Cruz Avenue intersection: Widen Sand Hill Road to add second eastbound left turn lane; Widen Sand Hill Road to add second westbound left turn lane; Modify signal phasing; Install an exclusive right turn lane on the northbound approach of Santa Cruz Avenue; and Provide dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. The applicant shall also pay the costs of installing an exclusive right turn lane on the northbound approach of Santa Cruz Avenue and providing dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. Conditions of approval 1.c and 12 for the SHIRE/RRI project, as adopted by condition of approval 2.c for this project, provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, with respect to any improvements within that jurisdiction, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share (subject to limitations based on engineering cost estimates) based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue: Mitigation measure 4.4-7(d) requires the applicant to pay a fair share of the costs of the following improvements to the Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue intersection mandated by the Menlo Park General Plan or recommended in the EIR: Widen northbound approach to add exclusive right turn lane. Install an additional southbound left -turn lane. Conditions of approval l.c and 12 for the SHRE/RRI project, as adopted by condition of approval 2.c for this project, provide that 1C 970702 lac 0031589 the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, as applicable, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share (subject to limitations based on engineering cost estimates) based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Middlefield Avenue/Willow Road: Mitigation measure 4.4-7(e), as modified by Condition 2.d of the conditions of approval, requires the applicant to pay its fair share of the following improvements to the Middlefield Avenue/Willow Road mandated by the City of Menlo Park general plan or recommended in the EIR, when the City of Menlo Park determines to proceed with these improvements. Add a second southbound left turning lane. Restripe eastbound approach. Modify signal phasing. Including a leading left turn phase in the signal phasing for the north and south directions. The timing of these improvements will be determined by the City of Menlo Park, through periodic monitoring and/or through subsequent environmental impact analysis and documentation. Condition 2.d partially implements this mitigation measure by requiring that the applicant shall either make signal timing improvements sufficient to return traffic levels of service at this intersection to level of service D, or contribute its fair share of the costs to construct the recommended intersection improvements. This obligation would not be triggered until current level of service falls to E or worse. Sand Hill Road/Santa Cruz Avenue and Junipero Serra Blvd./Alpine Road: Mitigation measure 4.4-7(h) provides that the applicant shall conduct an operational analysis of the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections to identify the appropriate combination of roadway and traffic signal improvements necessary to improve operation to LOS D during peak hours, if feasible. The EIR also recommends the following mitigation measures be implemented to mitigate cumulative traffic impacts within the City of Menlo Park, but does not provide for direct participation by the applicant in implementation of these mitigation measures. El Camino Real/Ravenswood Avenue: Mitigation measure 4.4-7(f) recommends that the following improvements to the El Camino Real/Ravenswood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: 11 970702 tac 0031589 I Widen northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. Widen westbound approach to add exclusive right turn lane. El Camino Real/Valparaiso Avenue/Glenwood Avenue: Mitigation measure 4.4-7(g) recommends that the following improvements to the El Camino Real/Valparaiso Avenue/Glenwood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: Restripe northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. Widen westbound approach to add exclusive right turn lane. Final design shall Include provisions for bicycle traffic. In addition, the EIR recommends that signal phasing at this intersection be modified to include split phasing in the east/west direction and a leading left turn phase in the north/south direction. The Council finds that these adopted mitigation measures, if implemented, will lessen the project's impacts on traffic at the four significantly affected intersections to a less than significant level, and will also substantially lessen the impact of the project's contribution to cumulative traffic at other intersections significantly affected by the Sand Hill Corridor projects collectively. Mitigation measures 4.4 -7(a) -(e) require the applicant to pay all or a fair share of the costs of physical improvements necessary to enable each of these affected intersections to serve anticipated cumulative traffic demands at acceptable levels of service. Mitigation measure 4.4-7(h) also provides for identification of appropriate additional intersection improvements should the City of Menlo Park elect to achieve a higher level of service and the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections. The Council recognizes that authority to approve the identified mitigation measures at three of the four intersections significantly affected by the project is vested in public agencies other than the City, specifically the City of Menlo Park (Sand Hill Road widening and related improvements in Menlo Park, mitigation measure 4.4-7(c), Sand Hill Road/Santa Cruz Avenue and mitigation measure 4.4-7(e), Middlefield Avenue/Willow Road); County of Santa Clara (mitigation measure 4.4-7(a), Arboretum Road/Galvez Street 12 970702 lac 0031589 • • intersection); the and County of San Mateo (mitigation measure 4.4-7(c), Sand Hill Road/Santa Cruz Avenue intersection). Responsibility and authority for implementing the recommended mitigation measures at the additional intersections cumulatively impacted by the project is also vested in other public agencies, specifically the City of Menlo Park (mitigation measures 4.4-7(f), El Camino Real/Ravenswood Avenue, and 4.4-7(g), El Camino Real/Valparaiso Avenue/Glenwood Avenue) and 4.4-7(d), Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue). The Council finds that the identified mitigation measures can and should be approved and implemented by these agencies. However, the Council also recognizes that in the event that one or more of the recommended mitigation measures are not approved or implemented by the appropriate responsible agencies, the project will result in significant adverse impacts on the Arboretum Road/Galvez Street, Middlefield Road/Willow Road and/or Sand Hill Road/Santa Cruz Avenue intersection(s), and will contribute to significant impacts at other intersections cumulatively affected by the Sand Hill corridor projects. Because it cannot presently be determined if or when the appropriate mitigation measures will be implemented by the respective responsible agencies, these impacts are considered by the Council to be potentially significant. 4.4-8 Construction activities could lead to temporary disruption of transportation system operation, as well as to permanent damage to elements of the system such as pavement and bridges. Mitigation measure 4.4-8(a) requires the applicant -to provide adequate off-street parking for all construction -related vehicles throughout the construction period. If adequate parking cannot be provided on the construction sites, a satellite parking area shall be designated, and a shuttle bus shall be operated to transfer construction workers to the job sites. Mitigation measure 4.4-8(b) provides that construction activities related to the project are prohibited from substantially limiting pedestrian access (e.g, by blocking pedestrian routes), without prior approval from the City of Palo Alto and/or Caltrans. Any approval shall require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4-4.8(c) provides that the applicant shall be prohibited from limiting bicycle access (e.g. by blocking or restricting existing routes) while constructing the project, without prior approval from the City of Palo Alto and/or Caltrans or the City of Menlo Park (depending upon the jurisdiction of the requested action). Any approval will require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(d) provides that the applicant shall be required to prohibit or limit the number of construction 13 970702 lac 0031589 material deliveries from 7 a.m. to 9 a.m., and from 4 p.m. to 6 p.m. on weekdays. Mitigation measure 4.4-8(e) provides that the applicant shall be required to prohibit or limit the number of construction employees from arriving or departing the site from the hours of 4:30 p.m. to 6 p.m. Mitigation measure 4.4-8(f) requires that all construction -related equipment and materials shall be delivered and removed on truck routes designated by the cities of Palo Alto and Menlo Park. Heavy construction vehicles shall be prohibited from accessing the sites from other routes. Mitigation measure 4.4-8(g) requires the applicant to repair any structural damage to public roadways, returning any damaged sections to original structural condition. The effectiveness of this measure shall be guaranteed by requiring surveys of road conditions before and after construction. Mitigation measure 4.4-8(h) prohibits the applicant from limiting access to public transit (e.g. by relocating or restricting access to bus stops or transfer facilities), and from limiting movement of public transit vehicles, without prior approval from the Santa Clara Transit Agency or other appropriate jurisdiction. Any approval will require submittal of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(I) provides that in lieu of mitigation measures 4.4-8(a) through (h), the project applicant may prepare detailed construction impact mitigation plans for approval by the City of Palo Alto Chief Transportation Official and City of Menlo Park Transportation Manager prior to commencing any construction activities with potential transportation impacts in their respective jurisdictions. The plan must address all aspects of construction traffic management necessary to eliminate or reduce transportation impacts to acceptable levels. Mitigation measure 4.4-8(j) requires the applicant to prepare and comply with a parking management plan approved by the Chief Transportation Official. The plan may not simply transfer the impact of temporary parking loss to adjacent surface streets, commercial districts, or residential neighborhoods, and must address specific measures identified in the EIR. The Council finds that adoption of these measures will lessen the project's potential construction phase traffic and transportation impacts to a less than significant level. These measures provide for comprehensive planning for construction traffic and establish standards, criteria and implementing measures which will ensure that significant interference with vehicle, bicycle, pedestrian and emergency vehicle access is avoided during all phases of construction. The adopted mitigation measures also require the applicant to offset parking demand created by loss of 14 970702 lac 003tS89 • shopping center parking spaces during construction phases by means which will not impact.. other parking facilities in the area. 4.5 AIR OU ITY 4.5-1 The iliio generated during the construction of the proposed projects could be harmful to nearby pollutant -sensitive land uses. Mitigation measure 4.5-1 requires the applicant to implement a construction phase program which includes the following measures to reduce generation of particulate matter on the project site during construction: - Water all active construction areas at least twice a day, or as needed to prevent visible dust plumes from blowing off -site. - Use tarpaulins or other effective covers for on -site storage piles and for haul trucks on public streets. - Pave, apply water three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas during construction. Sweep all paved access routes, parking areas, and staging areas daily (preferably with water sweepers). Sweep streets daily (preferably with water sweepers) if visible amounts of soil material is carried onto public streets. If the working area of any construction site exceeds four acres at any one time, implement the following additional measures: Apply (non-toxic) soil stabilizers to inactive construction areas. Enclose, cover, water twice daily, or apply (non-toxic) soil binders to exposed stockpiles. Limit construction site vehicle speed to 15 mph on unpaved areas. - Replant vegetation in disturbed areas as quickly as possible. If the working area of any construction site is located near any sensitive receptors, implement the following measure in addition to those listed above: - Suspend excavation and grading activity when winds exceed 25 mph. 15 970702 lac 0031589 • • The last mitigation would be applicable to the Stanford Shopping Center Expansion site where it approaches Ronald McDonald House and the Stanford University Medical Center. The Council finds that adoption of this measure will lessen the identified potential adverse construction phase impact to a less than significant level. Implementation of twice daily watering has been shown to reduce construction site PMi0 emissions by at least 50 percent. This practice, in conjunction with the other listed measures, will reduce PM,0 emissions during construction to less than the BAAQMD threshold of significance for all anticipated construction activity. 4.5-2 ROG, NO., and Rim emissions generated by motor vehicles and residential stationary sources associated with the proposed projects would exceed the 80 lbs/day threshold and could hinder regional and local attainment of State ozone and PMT. standards. Mitigation measure 4.5-2 (a) requires the City to implement mitigation measure 4.4-2(a), which provides final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed to ensure the circulation system will function as a part of regional or inter -city bicycle and pedestrian connections, thereby promoting increased use of bicycles or pedestrian travel by area residents. The Council has required that the plans for those projects incorporate this mitigation measure. Mitigation measure 4.5-2 (b) requires the City to implement mitigation measure 4.4-2(d), which requires the applicant to provide a bicycle and pedestrian actuated crossing phase of El Camino Real north of the proposed Sand Hill Road intersection, promoting increased bicycles or pedestrian accessibility of the shopping center. The RIR concludes that air pollution emissions from the project, resulting primarily from increased project -related vehicle traffic -- would be below the thresholds of significance for NOx, PM10 and ROG emissions recognized by the BAAQMD and utilized in the EIR. Due to continuing changes in automotive technology, further reductions are expected by the year 2010. The project therefore will not have a significant adverse effect on air quality. The EIR also concluded, however, that the project would contribute to significant air quality impacts from the Sand Hill Corridor projects collectively. The Council finds that this cumulative air quality impact is significant, despite adoption of the above identified mitigation measures. 4.5-4 Cumulative daily traffic along major roadways in the project and study areas would emit more NO., and pm6 with the implementation of the Sand Hill Road Projects, but emissions of ROG would decrease. The SIR found that neither the Stanford Shopping Center Expansion nor any of the other Sand Hill Corridor projects will 16 970702 Esc 0031589 • • individually produce significant air quality impacts. However, the three Sand Hill Corridor development projects collectively will result in a significant cumulative increase of NOx and PM10 emissions of in the project area. The EIR did not identify any mitigation measures for this area -wide cumulative impact. Cumulative traffic -related air pollution emissions are regulated through means beyond the City's jurisdiction and control. Individual vehicle emissions and automotive fuels are subject to regulation only by state or federal government. Regional traffic levels are also heavily influenced by past and future planning and land use decisions over which the City has no control. The Council therefore finds that no additional feasible mitigation measures are presently available to the City to substantially lessen this cumulative impact due to increases in regional traffic, and because the legal authority and responsibility, if any, for feasible mitigation measures is vested in other agencies beyond the City's control. The identified cumulative impact is significant. 4.6 NOISE 4.6-1 The noise generated during the construction of the proposed projects could be disruptive to nearby noise -sensitive land uses. Mitigation measure 4.6-1(a) provides that construction activities will be limited to the hours of 8:00 a.m. to 8:00 p.m. Monday through Friday, and if weekend work is necessary, to the hours of 9:00 a.m. to 8:00 p.m. on Saturday, and to the hours of 10:00 a.m. to 6:00 p.m. on Sunday. Mitigation measure 4.6-1(b) provides that construction equipment shall be outfitted and maintained with noise reduction devices (i.e., mufflers, enclosures for stationary equipment, etc.) to obtain at least an average 10 dBA reduction shown feasible in Table 4.6-5. Mitigation measure 4.6-1(c) provides that stationary noise sources (e.g., compressors, concrete mixers, etc.) shall be located on portions of the sites furthest away from residential and other noise -sensitive areas, and that acoustic shielding shall be used with such equipment. The Council finds that adoption of these measures will substantially lessen construction phase noise impacts of the project, but will not reduce these impacts to less than significant levels. The adopted measures will reduce noise generated by construction activities and will eliminate construction noise during normal sleeping hours. However, significant noise impacts will remain due to inherent noise generated by large scale construction activity and heavy equipment. 17 970702 lac 0031589 • • 4.6-3 Traffic generated by the proposed projects and other cumulative developments and the traffic accommodated by the proposed roadway improvements would impact existing and proposed residential and other sensitive land uses adjacent to roadways in the project and study areas. Mitigation measure 4.6-3(b) requires the applicant to construct a landscaped buffer strip with at least a 3 -foot -high berm along Sand Hill Road between Stanford Avenue and Oak Avenue in conjunction with implementation of the Sand Hill Road widening and realignment between Santa Cruz and Oak Avenues. Mitigation measure 4.6-3(c) requires the applicant to construct a soundwall 6 feet high or higher between Santa Cruz Avenue and Stanford Avenue in conjunction with implementation of the Sand Hill Road widening to reduce noise from traffic increases at the nearby intersection. Mitigation measure 4.6-3(d), as modified by Condition 2.e of the project conditions of approval, requires the applicant to monitor noise increases in residences in the designated areas along Sand Hill Road where the Sand Hill Road Corridor projects may be responsible for more than 50% of potential increases in traffic -related noise. If noise increases are detected, the applicant shall be responsible for the costs of measures such as additional insulation, double -glazed windows, or individual soundwalls as determined necessary by acoustic study to return interior noise levels in these residences to pre -project levels or to 45 dBa. Residents may also contribute any further funds necessary to further reduce interior noise levels to acceptable levels. The Council finds that these mitigation measures, if implemented, will substantially lessen significant cumulative traffic -related noise impacts along the Sand Hill Road corridor although these measures will not necessarily reduce cumulative noise impacts to a less than significant level for every residence affected by the project. Mitigation measure 4.6-3(d) provides for a fair share contribution by the applicant to the costs of physically upgrading affected residences with noise mitigation measures. Mitigation measures 4.6-3(b) and 4.6-3(c) provide for construction of physical barriers to reduce noise to acceptable levels at protected residences. The adopted mitigation measure 4.3-6(d) will impose responsibility for necessary monitoring of actual noise increases on the applicant and also imposes responsibility on the applicant to pay a share of actual mitigation costs in proportion to the applicant's responsibility for these impacts where the Sand Hill Corridor projects are the predominant cause of cumulative traffic -related noise impacts. The Council does not believe that the applicant can or equitably should be held responsible for more than a fair share of the costs of mitigating these potential cumulative noise impacts. Revisions made by the City to mitigation measure 4.3-6(d) are intended to strengthen the measure by fixing responsibility for noise monitoring on the applicant, and to also amend the measure to provide that the 18 970702 lac 0031589 • • applicant shall be financially responsible only for a fair share of the costs of implementing the mitigation measure. The Council recognizes that mitigation measure 4.6-3(d), as adopted, will not result in lessening of cumulative noise impacts at locations at which less than 50% of the cumulative traffic -related noise increase is attributable to the Sand Hill Corridor projects. The Council also recognizes that since implementation of mitigation measure 4.6-3(d) also requires the cooperation of affected homeowners, the physical improvements necessary to reduce noise levels at some affected residences to acceptable levels may not be constructed by choice of the owner. The Council therefore recognizes that notwithstanding adoption of the identified mitigation measures, cumulative traffic -related noise impacts may remain significant for some residences affected by the projects. With respect to mitigation measures 4.6-3(b) and 4.6-3(c), which will mitigate noise impacts on certain residences in Menlo Park, the Council further recognizes that although the conditions of approval require the applicant to accept responsibility for implementation of these mitigation measures, approval for implementation of these measures must` be obtained from the City of Menlo Park. The Council finds that implementation of these mitigation measures can and should be approved by the City of Menlo Park. The Council also recognizes, however, that in the event that approval for implementation of these measures is not obtained from Menlo Park, affected residences in Menlo Park would experience significant cumulative traffic -related noise impacts due to increased cumulative traffic on Sand Hill Road. 4.7 BIOLOGICAL RESOURCES 4.7-1 Implementation of the proposed projects would result in loss of trees and associated wildlife habitat. Mitigation measure 4.7-1(a) requires that Native trees removed for the projects shall be replaced at a ratio of 3:1 on a per acre basis by the same species from locally collected stock, and provides for additional replanting if survival rates fall below 80 percent. Mitigation measure 4.7-1(b) requires that non-native landscape trees removed for the projects be replaced on a two -to -one basis. Mitigation measure 4.7-1(c) provides that the City shall contract with an independent arborist to (a) review plans to provide for maximum retention of trees and necessary additional tree protection measures; b) monitor project construction ; and c) recommend changes in the tree removal plan as necessary during construction. Mitigation measure 4.7-1(e) requires that all trees adjacent to project construction areas which are not removed will be avoided and protected according to specified procedures incorporated into all construction and/or demolition contracts. 19 9'70702 Lac 0031389 • • The Stanford Shopping Center Expansion project will not result in loss of any native trees. The extensive removal of existing landscape trees is nevertheless considered a significant impact. The Council finds that adoption of the recommended mitigation measures will lessen the project's long and intermediate term impacts on trees to less than significant levels, and will substantially lessen but will not avoid significant adverse short term impacts (0-10 years). The adopted measures for retention and protection of existing trees to the extent possible during project construction and replacement of all trees removed as a result of the project at a greater than 1-1 ratio. These mitigation measures will therefore result in replacement of all trees lost. However, because it will take a number of years before replacement trees reach a level_ of maturity similar to those being removed, the project will result in a significant short-term impact on the quality of trees and related habitat value in the project area . 4.7-8 Ongoing operation of the proposed projects. could adversely affect aquatic life, including sensitive animal species, in San Francisquito Creek, by increasing runoff and non -point source urban pollutant loads. Mitigation measure 4.7-8(a) requires implementation of mitigation measures 4.9 -1(a) -(c), discussed below. Mitigation measure 4.7-8(b) requires implementation of mitigation measures 4.9-4(a) and (b), discussed below. The Council finds that adoption of these mitigation measures will lessen the project's potential runoff and pollution impact on aquatic life in San Francisquito Creek to a less than significant level. The adopted mitigation measures require preparation and implementation of construction phase and post -construction storm water runoff management plans which will incorporate recognized best management practices to minimize siltation and runoff of contaminants from the project areas. Residual silt and contaminant runoff reaching San Francisquito Creek, if any, will not constitute a sufficient addition to loads from existing development in the watershed to result in any measurable further deterioration of water quality conditions. 4.7-10 Implementation of the proposed projects, in conjunction with other proposed projects in the area would result in incremental loss of trees and associated wildlife habitat. Mitigation measure 4.7-10(a) requires implementation of mitigation measures 4.7-1(a, b, c, and e), discussed above, for all Sand Hill Corridor projects. Mitigation measure 4.7-10(c) recommends that all planning jurisdictions in the project area, Implement their respective tree protection and preservation ordinances. For those jurisdictions without such an ordinance, measures similar to those presented in mitigation measure 4.7-1 should be implemented on a project -by -project basis. 20 970702 lac 0031389 • • The conditions of approval for the project incorporate each of the project -specific. mitigation measures recommended in mitigation measure 4.7-10(a). The applicable recommended project -specific mitigation measures have also been adopted in the conditions of approval for each of the Sand Hill Corridor projects approved concurrently with the project. The Council finds that adoption of these project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level. Adoption and implementation of these measures in conjunction with the other Sand Hill Corridor projects will reduce the combined cumulative impact of these projects to a less than significant level. These measures generally provide for full replacement of trees lost due to implementation of the project, thus eliminating any significant cumulative impact. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects within the City or annexed to the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies .can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative loss of trees and related habitat from future projects is presently entirely speculative and unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the' Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative visual impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.7-15 Ongoing operation of the proposed projects, in conjunction with similar projects within the same watershed, could cause cumulative adverse affects on aquatic life, including sensitive animal species, in San Francisquito Creek, by increasing runoff and non -point source urban pollutant loads. Mitigation measure 4.7-15 requires implementation of mitigation measures 4.9 -7(a) -(c) for all Sand Hill Corridor projects. The conditions of approval for the project incorporate each of the applicable project -specific mitigation measures recommended in mitigation measures 4.9.7(a) -(c). The Council has also adopted the recommended project -specific mitigation measures as conditions of approval for the other Sand Hill Corridor projects approved concurrently with the project. The Council finds that adoption of these project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level. Adoption and implementation of these mitigation 21 970702 lac 0031589 • . measures in conjunction with the other Sand Hill Corridor projects will also reduce the combined cumulative impact of the projects to a less than significant level. The adopted mitigation measures generally provide for preparation and compliance with detailed Storm Water Pollutant Prevention Plans which will include specific measures to prevent excessive sediment or pollution runoff which might result in significant adverse effects on aquatic life or habitat values in San Francisquito Creek. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects within the City or annexed to the City. With respect to cumulative impacts from future development beyond the City's boundaries, jurisdiction and responsibility for adoption of recommended measures is vested in other public agencies. The Council finds that these agencies can and should implement these measures. Because the nature and extent of the potential cumulative impact from future projects is presently speculative and unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative impact resulting from increased runoff of sediment and pollutants into San Francisquito Creek. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.8 GEOLOGY. SOILS AND SEISMICITY 4.8-1 Expansive or weak soils could damage foundations by providing inadequate support. Mitigation measure 4.8-1(a) requires site specific soil suitability analysis be conducted and soil stabilization procedures and foundation design criteria be adopted in accordance with engineering criteria where the existence of expansive and compressible soil conditions is known or suspected. Mitigation measure 4.8-1(b) requires participation by the project's registered soil engineer as deemed necessary to oversee, verify, and report on soil engineering procedures and results. The EIR concludes that soil conditions encountered during construction could, but will not necessarily, create a risk of inadequate support for new construction associated with the project. The Council finds that adoption of these mitigation measures will lessen the potential impact of potentially expansive or weak soils to a less than significant level. These measures implement standard engineering procedures and safeguards for ensuring safe construction of new structures. 22 970702 1ac0031589 • • 4.8-2 The Stanford Sand Rill Road Corridor Projects area is subject to very strong seismically induced groundshaking which could threaten life and damage property. Mitigation measure 4.8-2(a) requires documented site -specific seismic -restraint criteria to be incorporated in the design of foundations and structures of the project which meet the minimum seismic -resistant design standards of CUBC Seismic Zone 4. Additional seismic -resistant earthwork and construction design criteria will be incorporated in the project where recommended by qualified experts. Roads, foundations and underground utilities in fill or alluvium shall be designed to accommodate settlement or compaction produced by seismic forces. Mitigation measure 4.8-2(b) requires on -site participation by the project's registered geological or geotechnical engineering consultant, as deemed appropriate, to oversee, verify, and report on seisruic-restraint procedures and results. Mitigation measure 4.8-2(c) requires that an engineering geologist be contracted for third party review of all geologic, soils and engineering reports prepared for the proposed projects. The Council finds that adoption of these measures will lessen the impact of exposure to seismic events to a less than significant level. These measures implement standard engineering procedures and criteria for preventing major building failures and resulting injury or loss of life from any seismic event reasonably anticipated to occur in the project area. 4.8-4 Implementation of any combination of the projects, in conjunction with cumulative development within San Mateo and Santa Clara counties and the cities of Palo Alto and Menlo Park, would increase the number of people and structures subject to strong seismic groundshaking and the subsequent risk of injury, loss of life and property damage. Mitigation measure 4.8-4(a) recommends that documented site -specific seismic -restraint criteria to be incorporated in the design of foundations and structures in the projects area, including the following (I) minimum seismic -resistant design standards shall conform to the CUBC Seismic Zone 4 Standards; (2) additional seismic -resistant earthwork and construction design criteria shall be incorporated as necessary, based on the site -specific engineering recommendations; (3) site preparation shall be supervised by geological or geotechnical consultants; (4) "as built" maps and a report shall be filed with the City, shoring details of the site geology, the location and type of seismic -restraint facilities, and documenting satisfactory seismic performance for buildings, roads, foundations and underground utilities. Mitigation measure 4.8-4(b) recommends requiring on -site oversight, verification and reporting by registered geological or 23 970702 lac 0031589 • • geotechnical engineering consultants where deemed appropriate by the City's Chief Building Official. The conditions of approval for the Stanford Shopping Center Expansion project and for each of the other approved Sand Hill Corridor projects incorporate measures equivalent to the project -specific mitigation measures recommended in mitigation measure 4.8-4(a). The Council finds that adoption of these project -specific measures will lessen the project's contribution to the identified cumulative impact to a less than significant level, and will also lessen the combined cumulative impact of the Sand Hill Corridor projects to a_ less than significant level. The adopted project -specific measures generally provide for incorporation of adequate seismic safety measures into all new construction as provided by mitigation measures 4.8 -2(a) -(c). Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be adopted in conjunction with any future projects approved by the City. With respect to cumulative impacts from future development outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that' these' agencies can and should implement such measures. Because the recommended mitigation measures rely in part upon compliance with existing seismic safety practices and standards, it is expected that other jurisdictions will implement the measures to a large extent. However, because the extent of the potential cumulative impact from future projects is presently unknown, and because the extent to which other agencies can and will implement the recommended mitigation measures beyond current minimum standards is uncertain, the Council cannot fully determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen the potential cumulative impact associated with increased development in the seismically sensitive region around the projects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.9 HYDROLOGY AND WATER QUALITY 4.9-1 Grading, excavation and construction activities could result in increased deposition of sediment and/or discharge of pollutants in the storm drainage system and San Francisquito Creek and adversely affect water quality. Mitigation measure 4.9-1(a) requires the applicant to prepare, retain and -implement a Storm Water Pollution Prevention Plan (SWPPP) which describes the site, erosion and sediment controls, means of material storage and waste disposal, implementation of approved local plans, post -construction control measures and maintenance responsibilities, and non -storm water management 24 970702 lac 0031589 • • controls. The plan shall implement appropriate Best- Management Practices ("BMPs") identified in the EIR Mitigation measure 4.9-1(b) requires that the SWPPP shall be prepared by a qualified professional and approved by the City's Director of Public Works prior to issuance of a building permit. The SWPPP shall be implemented and inspected as part of the approval process for the grading plans for each project. Mitigation measure 4.9-1(c) requires that all construction contracts include the City's construction contract Pollution Prevention Language as part of the project specifications. Because the project site is already largely paved and developed, the potential impact of the project is small. The Council finds that adoption of these measures will lessen the project's potential sedimentation and contaminant impacts on San Francisquito Creek to a less than significant level. The adopted mitigation measures implement regulatory requirements and practices demonstrated to prevent excessive or damaging runoff of sediments and pollutants from development sites. Residual runoff of sediments and contaminants from construction areas, if any, will not occur in sufficient quantities to significantly degrade existing water quality. 4.9-4 Increased impervious surface and landscaping associated with development of the Proposed Projects could increase urban contaminants in surface runoff potentially reducing water quality in San Francisquito Creek. Mitigation measure 4.9-4(a) requires implementation of mitigation measures 4.9-1(a) through (c) for all approved Sand Hill Corridor projects. Mitigation measure 4.9-4(b) requires that the SWPPP shall include in the final project design appropriate BMPs selected by the City, consisting either of detailed measures identified in the EIR or equivalent measures. Since the project site is already largely paved and developed, the impact is likely to be small. The Council finds that adoption of the recommended measures will in any event lessen the project's potential impact on San Francisquito Creek to a less than significant level. The adopted mitigation measures require implementation of design features and operational practices which will reduce contamination of exposed surfaces at the project site and trap or otherwise minimize runoff of such contaminants from the site. Residual contaminant runoff reaching San Francisquito Creek is not expected to constitute a sufficient addition to loads from existing development in the watershed to result in any measurable further deterioration of water quality. 25 970702 lac 0031589 • • 4.9-5 Project construction activities in combination with other construction projects in the Watershed could cumulatively increase sediment and other construction -related pollutants in San Francisquito Creek and adversely affect water quality. Mitigation measure 4.9-5(a) recommends that all area jurisdictions ensure that project applicants include BMPs in construction contracts implementing the requirements of NPDES Municipal Storm Water Permit #CAS029718. Mitigation measure 4.9-5(b) recommends that applicants for all area projects of five acres or more, be required to prepare a detailed SWPPP under the State General Construction Activity Storm Water Permit. Mitigation measure 4.9-5(c) . requires implementation of mitigation measures 4.9-1(a) through (c) for all Sand Hill Corridor projects. The recommended mitigation measures or equivalent measures have been incorporated in the conditions of approval for the Stanford Shopping Center Expansion project. The Council finds that adoption of these project -specific measures will lessen the project's contribution to potential cumulative sedimentation and contaminant impacts associated with construction to a less than significant level. Adoption of the recommended mitigation measures with respect to future development projects within the City's jurisdiction is beyond the scope of approvals granted for the project; however, the Council finds that the City can and -should require implementation of the recommended measures at the time future development projects are proposed. With respect to implementation of, the recommended mitigation measures by jurisdictions other than the City, the Council finds that implementation of such measures is within the jurisdiction and responsibility of other public agencies and that the recommended measures can and should be implemented by these agencies to the extent feasible. These measures are generally consistent with requirements imposed by state law. However, because the nature and extent of potential area -wide cumulative impacts from future development are presently unknown, and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative effects. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the Council. 26 970702 lac 0031589 • • 4.9-7 Increased impervious surface associated with development of the Stanford Sand Hill Road Corridor Projects and areas in the San Francisquito Creek Watershed could cumulatively increase urban contaminants in surface runoff potentially reducing water quality. Mitigation measure 4.9-7(a) recommends that all local jurisdictions ensure that future project applicants include BMPs as part of project design in accordance with San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) requirements. Mitigation measure 4.9-7(b) notes that it is within the jurisdiction of the SFBRWQCB to require that comprehensive SWPPPs and monitoring programs be implemented by all storm water dischargers associated with specified industrial activities, in compliance with the State's General Permits, and to require that such plans shall include BMPs or equally effective measures. Mitigation measure 4.9-7(c) requires implementation of mitigation measures 4.9-4(a) and (b) by all approved Sand Hill Corridor projects. The conditions of approval for the project incorporate each of the recommended project -specific mitigation measures or equivalent measures to mitigate identified potential cumulative contaminant impacts to San Francisquito Creek. The Council finds that adoption of these recommended measures will lessen the project's contribution to the identified cumulative impact to a less than significant level. The recommended mitigation measures have also been adopted in connection with approval of the other approved Sand Hill Corridor projects, and will lessen the combined cumulative impact of the projects to a less than significant level. Adoption of the recommended mitigation measures for future development in the City is beyond the scope of approvals granted for the project. However, the Council finds that the City can and should adopt equivalent measures for all future projects approved within its jurisdiction. With respect to impacts resulting from future development outside the City, jurisdiction and responsibility for implementation of recommended mitigation measures or equivalent measures is vested in other public agencies. The Council finds that these jurisdictions can and should implement such measures. However, because the nature and extent of potential cumulative impacts from future development is currently unknown, and the degree to which other jurisdictions will implement recommended mitigation measures is uncertain, the Council cannot determine at this time the extent to which the recommended measures will be implemented outside the City's boundaries and also cannot determine the extent to which these measures, if implemented, will lessen or avoid the identified potential cumulative impact. This cumulative impact therefore remains potentially significant. 27 970702 lac 0031589 • 4.10 PUBLIC SAFSTz 4.10-1 Implementation of the proposed projects could expose construction workers to unidentified existing soil and/or groundwater contaminants at levels which could cause illness. Mitigation measure 4.10-1(b) construction, a site assessment whether there are any hazardous northeast corner of the Quarry and underground tanks on the site. requires that prior to project shall be performed to confirm materials contamination at the Arboretum intersection from any Mitigation measure 4.10-1(c) requires that if investigation reveals evidence of chemical contamination, underground storage tanks, or other environmental impairments on the site, a remediation plan shall be prepared which will (1) specify measures to protect workers and the public; and (2) ensure clean up and disposal of contaminants and protect public health in accordance with federal, state, and local requirements. Work in the areas of potential hazard shall not proceed until the site remediation plan has been implemented. Appropriate agencies shall be notified as required. A site health and safety plan shall also be developed and implemented in compliance with OSHA requirements to ensure worker safety. The EIR concluded that although no known deposits or residues of unsafe contaminants exist on or adjacent to the project site, several underground tanks associated with old gas stations formerly located on corners of the property are known to have existed. Testing of these tanks and surrounding soils had not been completed at the time of preparation of the Final EIR, and the EIR therefore concluded that a potential existed for significant impacts related to hazardous substances associated with these tanks. The Council finds that the adopted mitigation measures will reduce this potential impact to a less than significant level by ensuring that the site is fully investigated and evaluated for the possible presence of harmful substances, and adequate remediation efforts undertaken if contaminants are detected in amounts which might pose and danger to workers or passers-by on the site. 4.10-2 Implementation of the proposed projects could expose construction workers to asbestos containing materials presently located in buildings and other structures, resulting in adverse health effects. Mitigation measure 4.10-2(a) requires that prior to building renovation, an asbestos survey shall be performed by a licensed asbestos abatement contractor on all building areas anticipated to be renovated during project construction. Mitigation measure 4.10-2(b) requires that all asbestos containing materials shall be removed and appropriately disposed of by a licensed asbestos abatement contractor prior to any building demolition. A site health and safety plan will be developed and 28 970702 lac 0031389 implemented in compliance with OSHA requirements to ensure worker safety. The EIR concluded that workers could potentially encounter asbestos -containing materials during renovation work on some existing buildings on the project site. The Council finds that the adopted mitigation measure will lessen this potentially significant impact to a less than significant level by requiring that all buildings scheduled for renovation be surveyed for asbestos containing materials prior to renovation, that any materials located be removed by qualified personnel using accepted safe practices, and that any residual potential impacts be addressed through appropriate safety measures incorporated into a health and safety plan for project workers. 4.10-4 Implementation of the proposed projects could expose construction workers to electrical transformers and/or fluorescent light ballasts potentially containing PCBs, and subsequent adverse health effects. Mitigation measure 4.10-4(b) provides that if the removal or relocation of any existing transformers is required, the applicant shall confirm whether or not it contains PCBs. If the transformer contains PCBs, it shall be removed and disposed of appropriately. Mitigation measure 4.10-4(d) requires that the need for removal, relocation or demolition of existing fluorescent light ballasts will be determined prior to project implementation. Any fluorescent lights affected by project shall be inspected to. determine the potential presence of PCBs, and any lights containing PCBs removed and appropriately disposed of by a licensed hazardous waste hauler per Title 22 requirements. Mitigation measure 4.10-4(e) requires that a site health and safety plan be developed in compliance with OSHA requirements to ensure worker safety prior to commencing removal and disposal of PCB -laden materials. The EIR concluded that electrical transformers and florescent light fixtures on the property could contain PCBs which could have a significant impacts on construction workers if accidentally released during demolition activities. The Council finds that the adopted mitigations measures will lessen this potentially significant impact to a less than significant level by providing for testing and safe removal of all transformers and florescent fixtures containing PCBs prior to commencement of renovation and construction activities. 4.11 UTILITIES,ENERGY, AND INFRASTRUCTURE 4.11-3 The proposed projects could use water wastefully. Mitigation measure 4.11-3 requires that in order to reduce water consumption, the project design shall incorporate measures to 29 970702 lac 0031589 maximize the efficient use of water and minimize total water consumption. Specific measures to be included are the following: All landscape designs shall incorporate and address the City Landscape Water Efficiency Standards. The project sites would be subject to an annual maximum water allowance for landscaping. The project applicant shall coordinate with the City of Palo Alto Utilities Department, Resource Management Division to determine other conservation related improvements that would apply to the projects. The EIR concluded that because final plans have not been completed by the applicant specifying how water, particularly for landscaping, would be efficiently used, there existed a potential that water could be used wastefully by the project. The Council finds that the adopted mitigation measure will lessen this potentially significant impact to insignificance by ensuring that final landscaping and construction plans meet current City Water Efficiency Standards and incorporate additional conservation measures if recommended by City staff. 4.11-4 Construction of the proposed improvements could disrupt existing water services. Mitigation measure 4.11-4 provides that prior to the start of construction of infrastructure, the project applicant shall provide a plan for review and approval to the City of Palo Alto Director of Utilities outlining the approach to be taken to minimize the impact to existing utilities and customers. The EIR determined that connection of infrastructure associated with the project to existing service lines and facilities could result in potentially significant interruptions_ of utility services for existing users, specifically interruptions of water service (Impact 4-11-4), wastewater service (Impact 4-11-11), electrical service (Impact 4-11-17) and gas service (Impact 4-11-24.) The Council finds that the adopted mitigation measure will lessen each of these potentially significant impacts to a less than significant level by requiring the applicant to submit and obtain approval of plans which will provide for completion of all utility connections for the project with the minimum necessary interruption of existing services. 4.11-7 Cumulative development could use water wastefully. Mitigation measure 4.11-7 provides that the City shall ensure that each new project approved within the City requiring ARB approval is required to be consistent with and implement the City policies and programs related to water conservation. The EIR concluded that existing City policies and programs are adequate to avoid cumulative wasteful use of water, and that a significant adverse impact had the potential to occur only if the 30 970702 lac 0031589 i • City failed to continue to implement these policies and programs. The adopted mitigation measure provides that the City will continue to implement existing water conservation policies by making compliance a condition of ARB approval for all new projects. The Council finds that this mitigation measure will lessen the potentially significant cumulative impacts to insignificance. 4.11-9 The proposed projects would require improvement of the existing 21 -inch wastewater line. Mitigation measure 4.11-9 requires that in the event that open -trench technology is used, the project applicant shall ensure that the new 24 -inch wastewater line is constructed coincident with, and placed in the right-of-way of, Palo Road, during Phase I of project construction, thereby avoiding potential biological impacts and conflicts with future uses associated with the alternative location of the line. The Council finds that adoption of this mitigation measure will lessen the potential significant adverse impacts associated with construction of a new 21" wastewater line to a less, than significant level. This mitigation measure requires the applicant to either use technology which avoids trenching and resulting tree removal in the Stanford Arboretum, or to relocate the route of the replacement. pipeline along existing right-of-way containing no significant environmental resources in order to avoid impacts to the Arboretum. 4.11-10 The proposed projects would generate additional wastewater flows that could exceed the capacity of the existing 27 -inch wastewater line. Mitigation measure 4.11-10(a) provides that if the proposed. project is developed prior to the Palo Alto Medical Foundation (PAMF) project,- the project applicant shall perform flow metering and a capacity study of the 27 -inch wastewater line, and shall be responsible for the costs of the improvement associated with the projects. All aspects of construction within the railroad right-of-way shall meet Peninsula Corridor Joint Powers Board (PCJPB) requirements and shall be approved by PCJPB. Mitigation measure 4.11-10(b) provides that if the PAMF. project is developed prior to the proposed projects, the project applicant shall coordinate with the Palo Alto Utilities Department and the PAMF project engineers to ensure that the proposed downstream 27 -inch wastewater line is enlarged with adequate capacity for the proposed Stanford West housing and Stanford Shopping Center Expansion projects. The SIR concluded that the project, in conjunction with the Stanford Shopping Center Expansion and proposed PAMF expansion project, would likely result in cumulative wastewater flows which exceed the capacity of the existing 27" wastewater line serving these projects. The Council finds that adoption of these mitigation measures will lessen this potential impact to 31 970702 lac 0031589 • • insignificance by requiring the applicant to bear the costs of all improvements determined necessary to provide adequate wastewater line capacity for all three projects, and that all improvements within the railroad right-of-way crossed by the pipeline be constructed with the approval of the PCJPB, which maintains the rail lines. 4.11-11 Construction of the proposed improvements could disrupt existing wastewater services. Mitigation measure 4.11-11 requires implementation of mitigation measure 4.11-4, discussed above. See findings re mitigation measure 4.11-4. 4.11-13 Cumulative development could require major infrastructure improvements to the existing wastewater system. Mitigation measure 4.11-13(a) recommends that the City of Palo Alto Utilities Department ensure that developers responsible for construction of new wastewater lines cooruinate with all other parties intending to utilize the line. Mitigation measure 4.11-13(b) recommends that sewer line capacity studies satisfactory to the City's Director of Utilities be conducted prior to initiating future cumulative development. Mitigation measure 4.11-13(c) recommends that all final designs for the sizing of new sewer mains Shall be based on infiltration from a 20 -year storm and peak base wastewater flow. The EIR concluded that lack of coordinated planning for future development could result in failure to adequately size area wastewater lines, resulting in future need to again upgrade these lines to provide needed capacity. The recommended mitigation measures provide for full evaluation and correct sizing of mains prior to cumulative development. The Council finds that adoption of these measures will lessen the project's contribution to this potential cumulative impact to a less -than significant level. These mitigation measures will also lessen the overall potential cumulative impact to a less than significant level since implementation of these measures will result in provision of adequate long-term capacity for all reasonably foreseeable development. 4.11-17 Construction of the proposed improvements could disrupt existing electrical services. Mitigation measure 4.11-17 requires implementation of mitigation measure 4.11-4 for all Sand Hill Corridor projects. See findings re mitigation measure 4.11-4. 32 9707021w0031589 4.11-24 Construction of the proposed improvements could disrupt existing gas services. Mitigation measure 4.11-24 requires implementation of mitigation measure 4.11-4 for all Sand Hill Corridor projects. See findings re mitigation measure 4.11-4. 4.12 PUBLIC SERVICES AND SCHOOLS 4.12-3 Increased traffic due to the construction of the proposed projects could reduce Palo Alto Fire Department (PAFD) response times, especially during special events on the Stanford Campus, peak commute hours, and seasonal holidays, when traffic flow is known to increase significantly. Mitigation measure 4.12-3(a) requires that as a condition of project approval, the project applicant shall prepare a construction vehicle management plan that: Uses established truck routes for large construction vehicles; - Includes an approved .construction plan, including scheduling, routes and methods, to minimize construction impacts during peak annual traffic periods (e.g., special events at Stanford University, holiday seasons, etc.). - Ensures that Sand Hill Road will remain open at all times in each direction to allow direct access to the Stanford University Medical Center from both directions. Mitigation measure 4.12-3(b) requires the applicant to prepare and comply with an emergency response plan that specifies alternate emergency response routes to the project sites and vicinity which meet the PAFD and Palo Alto Police Department (PAPD) response time goals. The Plan shall keep one lane in each direction of Sand Hill Road open at all times. The Council finds that adoption of this mitigation measure will lessen the project's construction -phase impact on emergency response times to a less than significant level.. The measure provides for detailed planning which will ensure that adequate alternate response routes and a minimum of one open lane on Sand Hill Road are maintained at all times during to construction for emergency traffic. 4.12-4 Cumulative development would increase the annual number of fire suppression service calls to the PAFD. Mitigation measure 4.12-4 identifies three alternative means for offsetting cumulative increased dema"ds on Palo Alto Fire Department resources. The conditions of approval for the project adopt the third of these alternate means, specifically: 33 9'70702 MC 0031589 The City will provide additional resources to the PAFD through the City's General Fund from the increased tax revenues generated by the Sand Hill Corridor projects and other future cumulative projects. The Council finds that adoption of this measure will lessen the identified cumulative impact on fire suppression services to a less than significant level for each of the Sand Hill Corridor projects and future development. Cost and revenue projections for the approved projects indicate that increased tax revenues from the projects and other potential future development will be more than adequate to fund additional resources for the PAFD necessary to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased PAFD resources identified in EIR mitigation measure 4.12-4, specifically (1) fair share applicant funding of new PAFD personnel, and (2) fair -share contributions from future projects, are not necessary based on current information to maintain adequate fire protection within the City and would result in imposing unnecessary special additional costs on new development. 4.12-5 Cumulative development would increase the annual number of medical emergency service calls to the PAFD. Mitigation measure 4.12-5 provides that future cumulative projects could pay fair share toward a medi-van unit; or, alternately, the City could provide additional medi-van resources to the PAFD with general fund increases from tax revenues generated by the projects and other future cumulative projects. The Council has adopted the second of these mitigation alternatives for the Sand Hill Corridor projects. The Council finds that the adopted mitigation measure will -lessen the identified potential cumulative impact on emergency medical services to a less than significant level. Cost and revenue projections indicate that increased tax revenues from the Sand Hill Corridor projects and other potential future development will be adequate to fund additional emergency medical resources as needed to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased emergency medical services identified in EIR mitigation measure 4.12-5, specifically that future development projects directly pay a fair share toward a medi-van unit or, is not necessary to maintain adequate level of emergency medical services based on current information. 4.12-6 Increased construction traffic from cumulative development could reduce PAFD response times. Mitigation measure 4.12-6 provides that as part of the project approval process, the City of Palo Alto Department of Planning and Community Environment shall ensure the following: All projects coordinate with the PAFD and PAPD to prepare an emergency response plan for the construction period 34 970702 lac 0031589 that specifies alternate emergency response routes to the project site and vicinity which meet the Departments' response time goals; and The Emergency Response Plan for all Sand Hill Corridor projects will specify procedures to allow simultaneous construction without increasing emergency response times to an unacceptable level. The Council finds that adoption of this mitigation measure will lessen the project's potential impact on PAFD emergency response times to a less than significant level. This ,measure ensures that detailed plans will be developed and implemented to ensure that existing or adequate alternative response routes will be kept open at all times to permit PAFD responses to all service areas within PAFD response time standards. 4.12-9 Increased traffic due to the construction of the proposed projects could increase police response times, especially during special events on the Stanford Campus, peak commute hours, and seasonal holidays, when traffic flow is known to increase significantly. Mitigation measure 4.12-9 requires implementation of mitigation measure 4.12-3(b). The Council finds that adoption of this mitigation measure will lessen the project's construction -phase impact,on emergency response times to a less than significant level. Mitigation measure 4.12-3(b) provides for detailed planning which will ensure that adequate alternate response routes for emergency traffic are maintained at all times during to construction. 4.12-10 Cumulative development would increase the annual number of police service calls to the PAPD. Mitigation measure 4.12-10 provides that one of the following measures shall be implemented to offset increased demand on Palo Alto Police Department resources, The project applicant shall provide fair share funding for additional PAPD personnel; The City shall require fair -share contributions from all future projects placing increased demand on the PAPD; or The City could fund additional PAPD resources from increased tax revenues generated by the projects and other future cumulative projects. The Council finds that adoption of this measure will lessen the potential cumulative impact of the project and of new development generally on police services to a less than significant level. Cost and revenue projections indicate that increased tax revenues from the Sand Hill Corridor projects and other potential 35 970702 lac 0031589 i • future development will be_adequate to fund additional emergency medical resources as needed to maintain current levels of service throughout the City. The Council also finds that the alternative means of funding increased emergency medical services identified in EIR mitigation measure 4.12-5, specifically that future development projects directly pay a fair share toward a medi-van unit or, is not necessary to maintain adequate level of emergency medical services based on current information. 4.12-12 Designs of cumulative development projects could present security risks to occupants and police patrol personnel. Mitigation measure -4.12-11 recommends that the City Department of Planning and Community Environment ensure that future project lighting and landscaping are reviewed with the PAPD to eliminate safety risks. The ARB shall provide final review and approval. The Stanford. Shopping Center Expansion project will not contribute to any cumulative security risk for citizens or police officers. Adoption of this mitigation measure as a policy governing review and approval of all future development within the City is beyond the scope of the decision and approvals granted for the project. However, the Council finds that the recommended mitigation measure can and should be implemented in relation to future development projects involving potential security problems within the City. 4.12-12 Increased construction traffic from cumulative development could increase PAPD response times. Mitigation measure 4.12-12 requires implementation of mitigation measure 4.12-6 by all approved Sand Hill Road Corridor Projects. This mitigation measure has been implemented by adoption of mitigation measure 4.12-6 for the each of the approved Sand Hill Corridor projects. The Council finds that implementation of mitigation measure 4.12-6 will lessen the cumulative impact of construction of the projects on PAPD response times to a less than significant level. 4.12-14 Cumulative development, including the proposed Stanford West Apartments Project, would cause X -12th grade enrollments to exceed PAIISD school capacity of 916 students or 12 percent in year 2004-2005. The EIR proposed the adoption of mitigation measure 4.12-14 to mitigate this identified cumulative impact. Mitigation measure 4.12-14 recommends that the City adopt a policy that encourages all future developers to contribute their fair share over and above payment of the development fee to mitigate school impacts. The Stanford Shopping Center Expansion project will not have any significant impact on school enrollments. Adoption of a City policy of encouraging future developers to contribute school 36 970702 lac 0031589 • • mitigation funds in excess of mandatory development fees is beyond the scope of approvals for the project. However, the Council recognizes that cumulative impacts on public schools from other future development are potentially significant, and further finds that these impacts would remain potentially significant whether or not the suggested mitigation measure is adopted as a policy of the City since contributions by developers would remain voluntary regardless of City encouragement. The Council has taken substantial steps to encourage the project applicant to discuss and fund mutually acceptable mitigation measures with affected school districts in relation to the Stanford West Apartments project, and can and will continue to take similar steps to encourage voluntary additional contributions by developers of future projects with the goal of fully offsetting any impacts which cannot be mitigated through mandatory development fees and tax revenue increases associated with new development. 4.12-17 The operation of the proposed projects would increase solid waste generation in the City of Palo Alto requiring increased diversion to meet the goals of AB 939. Mitigation measure 4.12-17(a) requires that as a condition of project approval, the applicant shall prepare and obtain approval from the City Public Works ,Department of a landfill diversion management program that meets the diversion goals of the Source Reduction and Recycling Element (SRRE) and AB939 . The program shall include specific provisions detailed in the EIR. Mitigation measure 4.12-17(b) recommends that the City require all new development projects to prepare operation recycling programs which will meet the AB939 diversion goal of 50 percent by 2000. The program shall include specific provisions detailed in the EIR. The Council finds that adoption of mitigation measure 4.12-17(a) will lessen the project's potential solid waste impacts to a less than significant level. This mitigation measure requires the applicant to develop, with City supervision, a plan which will ensure that solid wastes from the project are processed in a manner which ensure compliance with the recycling goals of AB939. Adoption and enforcement of mitigation measure 4.12-17(a) will also implement mitigation measure 4.12-17(b) with respect to the project. Adoption of mitigation measure 4.12-17(b) as a policy governing review and approval of all future development within the City is beyond the scope of approvals granted for the Stanford Shopping Center Expansion project. However, the Council finds that adoption of the proposed mitigation measure can and should be adopted in relation to future development projects within the City. 4.12-18 The proposed projects would increase solid waste generation in the City of Palo Alto during construction requiring increased diversion to meet the goals of AB 939. Mitigation measure 4.12-18 requires the applicant to prepare and implement a construction recycling plan approved by the City 37 970702 lac 0031589 • Public Works Department. The plan shall include specific steps to achieve the City's short-term SRRE diversion goal of 30-40 percent through various specified measures. The Council finds that adoption of this measure will lessen the identified potential solid waste impact to a less than significant level. The approved recycling plan will ensure that provision is made for recovering all recyclable wastes generated during construction, thus avoiding unnecessary placement of recyclable materials in landfills. 4.12-19 Cumulative development anticipated by the City through Year 2010, including the proposed projects, would increase solid waste generation by 5.5 percent over 1995 levels to 155,650 tons per year based on the projected growth of population and employees. Mitigation measure 4.12-19(a) recommends that the City require significant new development projects to prepare construction recycling plans as part of the project approval process. The construction plan shall include specific steps to achieve the AB939 diversion goal of 50 percent by 2000 through various specified measures. Mitigation measure 4.12-19(b) recommends that the City require new development projects to prepare long-term operational recycling programs as part of project approval process. The programs should meet the AB939 diversion goal of 50 percent by 2000, and include various additional specified elements These mitigation measures have been effectively applied to the Stanford Shopping Center Expansion project through the adoption of mitigation measures 4.12-17(a) and 4.12-18. The Council finds that adoption of these measures will reduce the project's contribution to potential cumulative solid waste impacts to a less than significant level. Adoption of mitigation measure 4.12-19(a) and 4.12-19(b) as policies governing review and approval of future development projects within the City is beyond the scope of the approvals granted for the project. However, the Council finds that the proposed mitigation measure can and should be adopted in relation to future development projects approved by the City. 5.2 GROWTH INDUCING IMPACTS The EIR concluded that the Stanford Shopping Center Expansion project will have a significant growth inducing impact in that upgrading of the existing 21" sewer line serving the project area to the 24° line necessary to serve the project and the Stanford West Apartments and Stanford West Senior Housing projects will remove an obstacle to growth of the Stanford Medical Center, which has announced tentative plans for expansion. The EIR does not identify any potential mitigation measures for this growth -inducing impact. The 24" sewer line will be constructed with the minimum size pipe available with sufficient capacity to ensure adequate service of the approved Sand Hill Corridor development projects. Since excess capacity will still be provided by this sewer line 38 970702 lac 0031589 which could facilitate expansion of the Stanford Medical Center or other development, this impact is potentially significant. The EIR concluded that the overall set of roadway improvements may serve to remove an obstacle to development of the contemplated 400,000 square foot expansion of the Stanford Medical Center. The traffic impacts of such development of the Medical Center as well as the impacts of cumulative development along the Sand Hill corridor were considered in the cumulative impacts analysis contained in the SIR. The EIR finds the impacts of such cumulative development within the Sand Hill corridor significant, as discussed elsewhere in these findings. 39 970702 lac 0031589 PART II ALTERNATIVES TO THE PROJECT The Council has also considered the alternatives to the proposed Stanford Shopping Center Expansion project analyzed in the EIR. Based on the following considerations, the Council has determined that all identified alternatives to the project are infeasible. The findings set forth below stating this Council's reasons for rejecting each alternative in favor of the project describe several separate grounds for rejecting each alternative, each of which this Council has determined constitutes an independent basis for this Council's decision to approve the project and to reject the proposed alternative. STANFORD SHOPPING CENTER EXPANSION No Project - No Action Alternative Under the No Action alternative, the applicant would retain the ability to expand existing shopping center facilities with 49,000 square feet of additional retail space. This development would include addition of new buildings to the center. The EIR assumed that this alternative would not include construction of any large new parking structures. The shopping center parking lot. would need to be reconfigured to compensate for parking spaces displaced for new construction, and loss of some existing trees in parking areas would occur. The overall number of parking spaces available at the shopping center could decr:?ase, particularly if the Sand Hill Road Extension and Related Roadway Improvements project were still implemented. Overall this alternative would result in similar although somewhat reduced impacts as the approved project, except that the additional visual impacts associated with a new parking structure would not occur. The Council finds that this alternative is infeasible because it would not achieve the project objective of maintaining the Stanford Shopping Center's current economic competitiveness and would not generate funding necessary to implement needed roadway improvements included in the Sand Hill Road Extension and Related Roadway Improvements. While the Sand Hill Corridor projects have been individually reviewed and analyzed by the City, the projects have been planned by the applicant as an integrated set of development proposals. The costs of the proposed Sand Hill Road Extension and Related Roadway Improvements to the applicant will be offset primarily from increased revenues generated by the Stanford Shopping Center Expansion. Stanford has indicated that limited expansion of the shopping center by 49,000 square feet will not increase revenues sufficiently to make funding of the roadway improvements economically feasible for Stanford, and that the roadway improvements included in the Sand Hill Road Extension and Related Roadway Improvements therefore would not be undertaken if additional expansion is not allowed. Funding for these roadway 40 970702 lac 0031589 • • improvements is.not available from the City or any other public agency_ and the improvements will not occur -if not funded by the applicant. The Council has determined the implementation of the Sand Hill Road Extension and Related Roadway Improvements project is necessary to alleviate already poor traffic conditions in the Sand Hill. Corridor and to accommodate anticipated cumulative traffic increases and traffic from the approved Stanford West Apartments and Stanford West Senior Housing projects at acceptable levels of service. Denial of the SHRE/RRI project to avoid the need for expansion of the Stanford Shopping Center is not a feasible alternative, nor is denial of the Stanford West Apartments project or Stanford West Senior Housing project to reduce the need for area road improvements a feasible_ alternative, for reasons stated in the findings and Statement of Overriding Considerations adopted for these projects. The reduced development permitted under the No Action alternative also would not achieve a basic reasonable economic objective of the project. Evidence received by the Council confirms that increasing the overall retail base and diversity of the Stanford Shopping Center is essential to maintaining its competitive status among regional shopping centers. The 80,000 square feet of increased retail space allowed under the approved project represents a reasonable minimum necessary to assure Stanford the ability to maintain its current relative attractiveness and competitiveness in relation to other regional shopping centers in the long term. In addition, development under the No Action alternative would not provide for increased parking to support new retail space and would be likely to result in an actual decrease in the current ratio of parking to retail space, rendering the shopping center less attractive to both retailers and customers. Overall, the potential incremental reductions in environmental impacts which would result from the No Action alternative do not justify this alternative in comparison with the approved project. In finding the No Action alternative infeasible, the Council does not find that additional growth of the Stanford Shopping Center is beneficial or desirable for its own sake. The Council is persuaded, however, that the additional expansion allowed under the approved project is necessary to maintain the overall long-term economic health and viability of the Stanford Shopping Center and its lessees, and to sustain the corresponding social and economic benefits to the community. No Project - No Development The No Development alternative would result in no expansion or new construction at the Stanford Shopping Center. This alternative would eliminate all impacts associated with the Stanford Shopping Center Expansion project, as well as all benefits resulting from the expansion. Long-term implementation of this alternative would require revisions to the City's existing zoning ordinance, which allows additional expansion of the Stanford Shopping Center by approximately 49,000 square feet. 41 9707021rc 0031589 • The Council finds that this alternative is infeasible for the same reasons as the No Action alternative. This alternative would not permit the applicant to achieve its reasonable economic objectives and would eliminate funding for needed area roadway improvements included in the Sand Hill Road Extension and Related Roadway Improvements. The adverse long-term economic consequences -of this alternative would also probably be far more severe than for the No Action alternative and could result a decline in the economic viability of the Stanford Shopping Center. As in the case of the No Action alternative, the Council finds that expansion of the existing Stanford Shopping Center facilities is necessary to maintain the overall attractiveness, competitiveness and economic health and viability of the shopping center and its lessees and corresponding benefits to the community. 160.000 Square Foot Expansion (Originally Proposed Project) As originally proposed by the applicant and evaluated in the EIR, the Stanford Shopping Center Expansion project included a total of 160,000 square feet of commercial space. The original proposed project also included construction of new multi -story parking structures adjacent to Sand Hill Road. The applicant modified the proposed parking structure plans during environmental review to relocate the proposed structures south of ,the main shopping center buildings and along Quarry Road in order to avoid unacceptable visual and land use impacts on the Sand Hill Road corridor. Even with the relocation of these structures, however, the 160,000 square foot alternative would result in greater direct and cumulative impacts than the approved project. The 160,000 square foot alternative is further, deemed infeasible by the Council. because it would result in an unacceptable adverse impact on the jobs/housing balance within the City and surrounding area and would in this respect, unacceptably offset the .overriding beneficial housing impacts of the Stanford West Apartments project approved concurrently with the Stanford Shopping Center Expansion. 75% Reduced Density Alternative The EIR also evaluated a 75% Reduced Density alternative for the project consisting of development of approximately 120,000 square feet of new commercial space. The Council assumes that relocation of proposed parking structures to Quarry Road and all applicable mitigation measures incorporated into the approved project could be incorporated into the 75% Reduced Density alternative to minimize impacts. This alternative would still result in incrementally greater direct and cumulative impacts than the approved project. The 75% Reduced Density alternative is further deemed infeasible by the Council because it would result in an unacceptable adverse impact on the jobs/housing balance within the City and surrounding area and would unacceptably offset the overriding beneficial housing impacts of the Stanford West Apartments project. 42 970702 4c 0031589 500 Reduced Density Alternative - The Draft EIR evaluated a 50% Reduced Density alternative consisting of development of approximately 80,000 square feet of new retail space. The 50% Reduced Density alternative evaluated in the Draft. EIR includes construction of parking structures adjacent to Sand Hill Road. The 50% Reduced Density alternative was given further consideration by the Planning Commission in its review of the DEIR, resulting in a Planning Commission recommendation for evaluation of a modified 50 % reduced density alternative which included relocation of parking structures and other proposed modifications to the location of new construction included in the project. This recommendation resulted in the "50% Stanford Shopping Center Expansion Alternative" evaluated in section 13.2 of the Final EIR. The Council finds that this 50% Reduced Density alternative as originally analyzed in the Draft EIR is infeasible and unacceptable because it would result in greater impacts than the approved project, particularly visual and land use impacts on the Sand Hill Road corridor. The DEIR 50% Reduced Density alternative would result in essentially the same direct and cumulative impacts as the approved project in many respects, e.g. traffic generation and potential construction phase impacts, but does not incorporate additional desirable design changes and refinements included in the approved project to improve the overall design of the shopping center project. The Council finds that the approved project represents a superior design which should be adopted by the City. "501 Stanford Shopping Center Expansion Alternative" At the recommendation of the Planning Commission, the Final EIR included evaluation of a Refined 50% Stanford Shopping Center Expansion Alternative which incorporated various design improvements. The approved project follows the Refined 50% Stanford Shopping Center Expansion Alternative, insofar as the new parking structure will be located on Quarry Road rather than Sand Hill Road, subject to changes and refinements added by the Council and by Stanford. The "Final Summary of Project Changes" noted that changes in the location buildings on the site would not have any significant environmental effect. No Housing Alternative The EIR also examined a "no -housing" alternative which would have consisted of approving 160,000 square feet of new commercial space for the Stanford Shopping Center and approving the Sand Hill Road Extension and Related Roadway Improvements project while denying approval for the proposed Stanford West Apartments and Stanford West Senior Housing projects. The primary purpose of this EIR alternative was to examine the effects on the area transportation system of approving only the proposed roadway improvements and proposed shopping center expansion elements of the Sand Hill Corridor projects. With respect to the Stanford Shopping Center Expansion project, the Council finds that the alternative is 43 970702 lac 003!589 • infeasible for the reasons previously stated in relation to the 160,000 square foot alternative. Houstn With Limited $hopping Center Development The EIR also examined a "housing with limited shopping center expansion" alternative consisting of (1) approval of the Stanford West Apartments and Stanford West Senior Housing; (2) construction of 49,000 square feet of new Stanford Shopping Center space only; (3) without any of the roadway improvements proposed in the Sand Hill Road Extension and Related Roadway Improvements project. The Council does not consider this alternative to be an alternative to the Stanford Shopping Center Expansion project. This alternative was evaluated in the EIR to examine the effects on the area transportation system of approving only residential development and limited shopping expansion, without major area roadway improvements. This alternative is not considered feasible because it would not provide an adequate roadway system to meet the needs of the approved Sand Hill Corridor projects and cumulative traffic growth expected in the area, and would result in the unacceptable traffic conditions reported in the discussion of this alternative in the EIR. With respect to the Stanford Shopping Center Expansion element of this alternative, the alternative is considered infeasible for the same reasons as the No Action alternative. Alternative Sites The EIR did not evaluate potential alternative sites for the proposed Stanford Shopping Center expansion for the reason that such alternatives would be fundamentally inconsistent with the nature of the proposed project and would not advance the basic project objectives of enhancing the attractiveness and competitiveness of the Stanford Shopping Center. Evidence received by the Council confirms that increasing the overall retail base and diversity of the Stanford Shopping Center is essential to maintaining its competitive status among regional shopping centers. Construction of new commercial retail space at other locations would not achieve the basic objectives of the project. The Council also has received no evidence that construction of additional commercial space at any alternate site would result in fewer or less severe environmental impacts than the Stanford Shopping Center Expansion project. The Council therefore finds that alternative sites do not constitute reasonable or potentially feasible alternatives to the Stanford Shopping Center Expansion project and that alternative sites for the Stanford Shopping Center Expansion were therefore reasonably not evaluated in the EIR. 44 970702 lac 0031589 EXHIBIT $ SAND HILL ROAD EXTENSION. WIDENING & RELATED ROADWAY IMPROVEMZNTS COUNCIL FINDINGS CONCERNING MITIGATION OF ENVIRONMENTAL IMPACTS AND CONSIDERATIONS OF ALTERNATIVES The City Council of the.City of Palo Alto ("Council") has read and considered the Final Environmental Impact Report ("EIR") prepared for the Sand Hill Road Extension and Related Roadway Improvements ("SHRE/RRI") project. The EIR has been prepared for five projects including the Stanford West Apartments, Stanford West Senior Housing, Stanford Shopping Center Expansion, SHRE/RRI projects, referred to collectively herein as the "Sand Hill Corridor projects," and- the Pasteur Drive Parcel Annexation project. These projects are described in Chapter 3 of the EIR, and include, as approved by the Council, the changes and revisions described in Chapter 11 and in the "Final Summary of Project Changes," made a part of the Final EIR by the certifying resolution. Pursuant to Section 21081(a) of the Public Resources Code, the Council has considered each environmental impact of the Sand Hill Road Extension and Related Roadway Improvements project identified in the EIR, and each of the mitigation measures and project alternatives evaluated in the EIR. The Council's detailed findings for each significant environmental impact or potentially significant environmental impact identified in the EIR are set forth below. Each significant orpotentially significant environmental impact identified in the EIR is listed in bold. Those mitigation measures adopted or partially adopted by the Council are also numbered in bold. The Council's reasons for rejection or partial rejection of certain mitigation measures and reasons for selection among alternative potential mitigation measures are described where appropriate. The Council's reasons for rejecting specific alternatives to the project identified in the EIR are stated in Part II of these findings. 1 970702 laic 0031590 PART i CHANGES AND MITIGATION MEASURES ADOPTED TO REDUCE IMPACTS 4.1 LAND USE The EIR identified the following potential significant land use effects of the Sand Hill Road Extension, Widening and Related Roadway Improvements project. 4.1-1 The proposed projects could result in a substantial change in the character of the land uses on or around the project sites. 4.1-5 Implementation of the proposed projects, in conjunction with cumulative development within the Sand Hill Road Corridor, would result in a change in character in the area. The EIR concludes that there are no feasible mitigation measures available which will substantially reduce the identified significant land use impacts and that these impacts are therefore unavoidable. The Council also finds that changes to the existing character of the Sand Hill corridor as a result of the project, both individually and in conjunction with the Sand Hill Corridor development projects approved concurrently with the project, are significant. The conditions for approval of the project, however, incorporate a number ofmitigation measures which will lessen the overall severity of these impacts by reducing visual impacts, providing for replacement of trees and restoration of habitat affected by the project of trees, enhancing opportunities for pedestrian and bicycle travel in the Sand Hill Road corridor and mitigating the potential noise impacts on neighboring residents. These measures are discussed in greater detail in the findings pertaining to mitigation of cultural, visual, transportation, noise and biological impacts. The project has also been modified to reduce the extension of Sand Hill Road between Arboretum and El Camino Real to two through traffic lanes, thus substantially reducing the visual impact and overall change of character of road development along this section of the Sand Hill corridor. Despite these measures, however, the impact remains significant. Project Areas Outside the City Authority and responsibility for mitigating impacts of those portions of the project west of San Francisquito Creek, including relocation of portions of the golf course, is vested in the City of Menlo Park, and, to a limited extent, the County of Santa Clara and County of San Mateo. The EIR also identifies mitigation measures which, if adopted by these agencies, will reduce the project's overall impact on the existing land use of the area, and will in some cases, if implemented, actually result in an improvement in 2 970702 b 0031590 existing conditions._ The Council finds that in the event that elements of the project within the City of Menlo Park, County of Santa Clara and County of San Mateo are approved, these measures can and should be adopted bythe respective responsible agencies to lessen the adverse impacts of the project, although the impacts will remain significant. 4.2 VISUAL QUALITY/LIGHT AND GLARE 4.2-1 The proposed projects would result in major visual changes within the Sand Hill Road corridor for viewers traveling on Sand Hill Road. Mitigation measure 4.2-1(h), as applicable to the City, requires that planted crib walls or other means of allowing interplanting or overhanging of vegetation should be incorporated if architecturally and technically feasible in the retaining wall southeast of the San Francisquito Creek bridge. The Council finds that adoption of this measure will lessen the visual impacts of the project on travelers on Sand Hill Road, but will not reduce the impact to a less than significant level. The Council also finds that other changes and mitigation measures have been incorporated into the project and conditions of approval of the project which will lessen the project's overall visual impacts to drivers, bicyclists and pedestrians on Sand Hill Road to the extent feasible. These changes and mitigation measures include the reduction of the Sand Hill Road extension from four lanes, as originally proposed, to two through lanes and provisions for installation and maintenance of landscaping and medians in the project conditions of approval. Additional changes and mitigation measures have also been adopted in conjunction with the other proposed Sand Hill Corridor projects to also reduce overall visual. impacts on travelers in the Sand Hill Corridor. However, notwithstanding adoption of these changes and mitigation measures, the overall adverse visual impacts of the project for travelers on Sand Hill Road will remain significant, due to the substantial change in existing conditions which will result from construction of additional paved traffic and bicycle lanes, increased number of intersections, traffic signals and other road improvements. Rejected Mitigation Measures Mitigation measure 4.2-1(I) would require that the proposed bicycle and pedestrian path be realigned, if feasible, off of the road shoulder and set back from the road east of the San Francisquito Creek crossing. Vegetation screening would also be established between the path and road if feasible. The City Planning Commission recommended rejection of this mitigation measure on the basis of testimony that this proposed mitigation measure would adversely affect bicycle use of the proposed pathway. The Council finds that implementation of this mitigation measure is infeasible and undesirable due to potential adverse effect on bicycle use, and because the cost and design 3 970702 lac 0031590 problems involved in implementation of this measure are not justified by the marginal and very localized decrease the measure, would achieve in overall visual impacts of the project. Mitigation measure 4.2-1(j) proposes narrowing of the proposed road improvements to fewer lanes in the area of San Francisquito Creek at both the bridge crossing and the proposed extension area. Center median design should be revised to permit additional center median tree planting in this area and the area east of Santa Cruz Avenue. The Council has required reduction of the Sand Hill Road extension from Arboretum to El Camino Real to two lanes, thus partially implementing this measure. However, with respect to restricting Sand Hill Road to fewer than four lanes at the San Francisquito Creek crossing, the Council finds that implementation of this proposed mitigation measure is infeasible and undesirable because long-term retention of Sand Hill Road as a two lane road west of Arboretum is not practical in view of anticipated regional transportation needs and vehicle traffic demands. Studies performed for the EIR indicate that cumulative traffic on Sand Hill Road, together with traffic from the other approved Sand Hill Corridor projects, cannot be accommodated on a two-lane Sand Hill Road west of Arboretum at acceptable levels of service and without causing substantial unacceptable delays for vehicle traffic in the Sand Hill Corridor. The Council also recognizes that the City of Menlo Park may, as a practical matter, independently impose this mitigation measure as it applies to the San Francisquito Creek bridge because the bridge widening will required approvals from both the City and Menlo Park. The Council does not recommend, however, that Menlo Park adopt this as a mitigation measure for the reasons stated above. Project Areas Outside the City With respect to those portions of the project located west of San Francisquito Creek and outside of City territory, the EIR recommended the following mitigation measures: Mitigation measure 4.2-1(h) provides for a number of measures to reduce visual impacts along the expanded Sand Hill Road in Menlo Park, including the following. Mitigation measure 4.7-1(f) provides for preservation of a large elderberry tree adjacent to the expanded Sand Hill road. (This has already been incorporated into the plans.) The retaining wall east of the Sand Hill Road Bridge shall be kept to the minimum necessary length and height. Materials used shall be in keeping with the character of the scenic roadway and plantings shall be used to obscure the view of the wall. Mitigation measure 4.2-1(j) proposes, in part, that center median designs should be revised to permit additional center median tree planting in the area east of Santa Cruz Avenue. 4 970702 !ac 0031590 • Jurisdiction and responsibility for adoption and implementation of these measures is vested in the City of Menlo Park. The Council finds that in the event the portions of the project- within Menlo Park are approved," these mitigation measures can and should be adopted by Menlo Park. If implemented, these measures would lessen but would not eliminate the significant visual impacts of the project within Menlo Park due to the overall magnitude of changes in existing setting resulting from the project. 4.2-5 The proposed projects would diminish the visual quality of the City's wooded north entry on El Camino Real frontage adjacent to San Francisquito Creek. Mitigation measure 4.2-5(a) requires that the Sand Hill Road extension be realigned approximately 40 feet southwards to more closely coincide with the bounds of the existing Stanford Shopping Center parking lot where it approaches El Camino Real-. Mitigation measure 4.2-5(b) requires that the Sand Hill Road/El Camino Real intersection be redesigned so that new lanes on El Camino Real are located within the existing pavement area of El Camino Real, and do not interfere with the wooded gateway area near the creek. Tree removal as a result of the widening of El Camino Real, shall not be allowed. The final landscape plan shall be modified to increase the amount of major tree planting at both the intersection and the portions of the southern edge of Sand Hill Road visible from the intersection, in order to reduce post -construction views into the shopping center parking lots, and if possible, reduce the visibility of the increased scale of the intersection. Both of these measures have been incorporated into the final design of the approved project. The Council finds that adoption of these mitigation measures will lessen the identified visual impacts to a less than significant level. These measures will preserve the existing wooded area in the area. of the gateway and preserve existing roadway width and frontage along El Camino Real, thus generally preserving the existing visual character of the gateway area and eliminating the potential impacts identified in the EIR. 4.2-6 The proposed projects would diminish the visual quality of the El Camino Real frontage between San Francisquito Creek and Quarry Road. Mitigation measure 4.2-6(a) requires the applicant to prepare and implement design guidelines or controls for development of the retail structure at Quarry Road and El Camino Real to ensure compatibility with the area, subject to approval by the Palo Alto Architectural Review Board and Planning Commission. Alternately, the applicant may remove this structure from the site plan, relocating the square footage to other portions of the Shopping Center if feasible. As discussed below, the Council has adopted the mitigation measure, rejecting the alternative. 5 -9'70702 lac 0031590 Mitigation measure 4.2-6(b) requires the intersection of Quarry Road and El Camino Real to be redesigned to improve overall visual quality and pedestrian operations, including the following specific changes: (a) reduce the width and number of proposed lanes of El Camino Real; (b) include a minimum 10 -foot wide landscaped median and pedestrian refuge area in the center median of El Camino Real. Mitigation measure 4.2-6(c) provides that if mitigation measures 4.2-1(1), 4.2-5(b) and 4.2-6(b) are all adopted, the applicant shall be required to conduct a detailed study of traffic progression and traffic signal coordination on El Camino Road and prepare a signal coordination plan. The plan shall encompass signalized intersections on El Camino Real from Embarcadero Road to the proposed Sand Hill Road extension and must demonstrate that northbound left -turn queues at both the Quarry/El Camino Real and Sand Hill Road/El Camino Real intersection will not obstruct northbound through lanes. Mitigation measure 4.2-6(d) requires that large evergreen shrubs or evergreen trees be incorporated in the final landscape plan along the north edge of Quarry Road and other areas near the corner of El Camino Real, in order to maintain some visual screening of the parking lot areas from the new intersection during winter months. The Council finds that adoption of these mitigation measures will lessen the identified impact to a less than significant level. These measures provide for modifications that diminish the extent of visual changes in the affected project area and for further design improvements to ensure compatibility with the existing visual character of the area. Mitigation measure 4.2-6(c) is designed to offset any adverse traffic impacts which will result from implementation of these measures. With respect to mitigation measure 4.2-6(a), the Planning Commission considered the alternative of eliminating the proposed retail building near Quarry Road and El Camino and recommended against this alternative. The Council also finds that relocation of this building is unnecessary and would defeat one of the design objectives of the Shopping Center expansion plans, specifically to provide an improved transition from the central shopping area of the Stanford Shopping Center to El Camino Real and adjoining portions of the City. The project conditions of approval implement the mitigation proposed in mitigation measure 4.2-6(a)rather than the alternative. The Council finds that this measure will mitigate the adverse impact associated with the original design of the outlying building to a less than significant level. 4.2-8 Visual disturbance from construction of the proposed projects could have temporary adverse visual impacts. - Mitigation measure 4.2-8 requires that on -site staging and storage of construction equipment and materials should be minimized to reduce visual disturbance during construction. Equipment and material storage that does occur on -site should be visually 6 970702 lac 0031590 • ! screened. Graded areas should be watered regularly to minimize fugitive dust. Construction should be staged and scheduled to minimize the duration of disturbance in each affected viewshed. The Council finds that adoption of this mitigation measure will lessen the adverse visual impact of project construction, but will not reduce this impact to a less than significant level. The adopted mitigation measure will limit the duration and visibility of construction equipment and grading activities on the site, but will not eliminate the significant unavoidable visual impact necessarily associated with major construction activities on the site. This impact therefore remains significant. Project Areas Outside the City The Council finds that the adoption and implementation of these measures on portions of the project outside the City is within the jurisdiction and responsibility of other public agencies, primarily the City of Menlo Park, and that these mitigation measures can and should be adopted in the event that project approvals are granted by Menlo Park. The Council also recognizes, however, that in the event that -Menlo Park approves the project but does not implement the recommended mitigation measures, significant adverse impacts could result. 4.2-9 The proposed projects, in conjunction with cumulative developlment in the Sand Hill Road Corridor, could adversely affect the visual character of the corridor for viewers traveling on Sand Hill,Road. The EIR recommended adoption of mitigation measure 4.2-9 to mitigate this identified cumulative impact. Mitigation measure 4.2-9 requires that mitigation measures 4.2-1(a-1) be implemented for all the Sand Hill Road Corridor Projects. The Council has adopted mitigation measure 4.2-1(h) and partially implemented mitigation measure 4.2-1(j), but has determined that implementation of mitigation measures 4.2-1(I) and the narrowing of Sand Hill Road to two lanes at the San Francisquito Creek crossing (mitigation measure 4.2-1(j), are infeasible and undesirable for reasons previously stated. The Council finds that the adopted measures will lessen the project's contribution to cumulative visual impacts along the Sand Hill Road corridor, but that these impacts will remain significant. Due to the major change in visual character associated with extending, widening and adding related improvements to Sand Hill Road, these impacts would also remain significant even with the adoption of the additional mitigation measures identified in the BIR. With respect to cumulative visual impact resulting from the other Sand Hill Corridor projects, the additional project -specific mitigation measures recommended in mitigation measure 4.2-9 have been adopted, partially adopted, or rejected as stated in the findings for the Stanford West Apartments, Stanford West Senior Housing and Stanford Shopping Center Expansion projects. To the extent these measures have been adopted, they collectively will 7 970702 lac 0031590 i reduce the significant adverse cumulative visual impact of the Sand Hill Corridor projects, but will not reduce the impact to a less than significant level. This cumulative impact therefore remains significant. The Council recognizes that future development, to the extent allowed in the Sar..d Hill corridor, will continue to add to the significant cumulative visual impacts associated with the approved projects. Project Areas Outside the City With respect to the project's contribution to cumulative visual impacts within the. City of Menlo Park, the Council finds that in the event the portions of the project within Menlo Park are approved, the applicable provisions of recommended mitigation measures 4.2-1(h) and (j) can and should be implemented by the approving agency. If implemented, these measures would lessen the cumulative visual impact but would not reduce it to a level of insignificance. 4.2-12 The combined visual affect of proposed projects could adversely alter views within the El Camino Real viewshed. Mitigation measure 4.2-12 requires implementation of mitigation measures 4.2 -6(a -c), discussed previously. The recommended mitigation measures have been adopted as described in the findings for Impact 4.2-6. The Council finds that adoption of these measures, together with adoption of measures in conjunction with the approval of the Stanford Shopping Center Expansion, will reduce to insignificance the project's contribution to cumulative visual impacts on the El Camino Real viewshed for the reasons stated in relation to Impact 4.2-6. 4.2-13 The proposed projects, in conjunction with cumulative development, could generate light and glare from buildings and roadways that could have adverse effects on nearby residents and on -coming drivers along Sand Hill Road. Mitigation measure 4.2-13 provides that interior and exterior light sources associated with all of the approved Sand Hill Corridor projects shall be shielded or directed in such a manner as to prevent visibility of the light sources and to eliminate light spillover beyond the perimeter of the proposed project. Specific measures recommended in accordance with section 18.64.030 of the Palo Alto Municipal Code include the following: (a) Exterior light fixtures on the housing buildings should be mounted no higher than 15 feet at the rear of the buildings. (b) Lighting of the building exterior and parking lot should be of the lowest intensity and energy use adequate for its purpose. 8 970702 lac 0031 590 (c) Unnecessary continued illumination, such as illuminated signs, should be avoided. (d) - Timing devices should be considered for exterior and interior lights in order to minimize light glare at night without jeopardizing security. The Council finds that adoption of this measure will lessen the project's contribution to potential cumulative light and glare impacts to insignificance. While increased light and glare on roadways is an unavoidable and expected effect of the project, the recommended mitigation measures provide for avoidance of unnecessary impacts from signs and lighting associated with the project. The adopted mitigation measures, in conjunction with landscaping which will reduce passage of light and glare from roadways to residences, will have the effect of eliminating substantial spillover of light from the project sites and will therefore reduce any potential cumulative impact to a less than significant level. This mitigation measure has also been incorporated into the conditions of approval for other approved Sand Hill Road Corridor projects and will therefore eliminate any potential significant cumulative effect by confining the impacts of each project to its own location. Project Areas Outside the City Adoption and implementation of these measures on portions of the project outside the City is within the jurisdiction and responsibility ofother.public agencies, primarily the City of Menlo Park. The Council finds that the recommended mitigation measures can and should be adopted in the event that project approvals are granted by Menlo Park. The Council also recognizes, however, that in the event that Menlo Park approves the project but does not implement the recorntended mitigation measures, significant adverse impacts could result. 4.3 CULTURAL RESOURCES 4.3-1- Implementation of the proposed projects would result in damaging effects on important historic and/or prehistoric archaeological resources. Mitigation measure 4.3-1(b) requires that prior to development the applicant shall conduct a data recovery program on all areas in which construction is believed to have a potential to result in significant archaeological impacts. The program shall consist of an initial phase of intensive subsurface archaeological testing meeting minimum standards specified in the EIR. Significant resources encountered shall be subject to recovery, preservation and study as provided in mitigation measure 4.3-1(c). All work shall be subject to review and monitoring by an independent archaeologist engaged by the City. Mitigation measure 4.3-1(c) requires manual excavation and recovery of archaeological resources from any areas encountered 9 970702 !ac 0031590 • during .construction which are determined to hold important archaeological resources and for the recovery, preservation and study of these resources. The measure also provides for ongoing monitoring of construction activities in potentially sensitive areas of the site and for preparation of further detailed procedures to ensure protection and recovery of any significant resources encountered in such areas. The plans shall include (a) provisions for artifact cataloging, analysis, and curation; (b) identification and coordination with most -likely Native American descendants concerning monitoring and reburial of Native American remains, if any are encountered; (c) plans for preparation of technical reports; (d) analysis and preservation of artifacts and documentation and analysis of non -recoverable site features. All of the foregoing shall be performed in accordance with current scientific and professional standards. Mitigation measure 4.3-1(f) provides that construction activities involving substantial ground disturbance (greater than 12" in depth) near any known archaeological site shall be subject to monitoring. Mitigation measure 4.3-1(g) provides that if previously unidentified cultural resources are discovered during construction, work shall cease in the immediate area until qualified archaeologists assess the significance of the resources and make mitigation recommendations (e.g., manual excavation of the immediate area), if warranted. Mitigation measure 4.3-1(h) requires the applicant and contractors to comply with the requirements of Section 7050.5(b) of the California Health and Safety Code if Native American burials or other possible Native American human remains are located during construction. This code section requires that a Native American Most Likely Descendant (determined in consultation with the Native American Heritage Commission) be notified within 24 hours and appropriate provisions made for appropriate reburial. This and related sections of.the Public Resources Code also provide that remains shall be protected from further construction work or vandalism. Mitigation measure 4.3-1(k) provides with respect to the project that construction activities shall be subject to archaeological monitoring in the area of the Sand Hill Road Extension, and for road improvements in all other areas for which a potentially significant impact has been identified, where ground disturbance will exceed 24 inches below existing grade. Monitoring may be conducted on an intermittent basis only where, in the opinion of the applicant's archaeologist and the City's archaeologist, soils are culturally sterile. Construction personnel shall be required to contact the applicant's archaeologist in the event that suspected cultural resources are uncovered in the absence of a monitor The Council finds that adoption of these mitigation measures will lessen the project's impacts on archaeological resources 10 970702 lac 0031590 within the City to a less than significant level. Presently known archaeological resources which may be affected by the project are limited to an area close to the San Francisquito Creek bridge. The adopted mitigation measures will ensure that all -.such resources which cannot be avoided during construction activities will be identified, removed and preserved for further study in accordance with accepted scientific standards, ensuring no loss of scientific or historical value of the resources. The adopted mitigation measures also ensure that any additional, presently unknown, important archaeological resources in areas affected by the project will similarly be identified, removed and preserved. The adopted measures also ensure that proper respect will be afforded any burials and any other culturally important Native American remnants which might be impacted by the project. Project Areas Outside the City Adoption and implementation of these measures on portions of the project outside the City is within the jurisdiction and responsibility of other public agencies, specifically the City of Menlo Park and Counties of Santa Clara and San Mateo. The Council finds that the above identified mitigation measures can and should be adopted in the event that approvals are granted by these agencies. The Council also recognizes, however, that in the event that these agencies approve elements of the project within their jurisdiction but do not implement the recommended mitigation measures, significant adverse impacts will result. Rejected Mitigation Measure The EIR also proposed an alternate mitigation measure 4.3-1(a) which has not been adopted by the City. Mitigation measure 4.3-1(a), as it relates to the project, would require that road and bridge widening in the vicinity of San Francisquito Creek be limited to the existing road surface area. The Council finds that this mitigation measure is infeasible and undesirable because the measure would effectively prohibit widening of the roadway and bridge to four lanes and therefore fail to achieve the basic objective of the project of providing increased traffic capacity along Sand Hill Road. The Council also does not recommend adoption of this mitigation measure by Menlo Park in conjunction with its approval of the bridge widening and Sand Hill Road widening for these same reasons. Because alternate mitigation measures are available and have been implemented to reduce all potential impacts to insignificance, the Council finds that the proposed mitigation measure is not justified in view of its substantial adverse effects it would have on traffic in the Sand Hill Road corridor. The Council recognizes that approval for the bridge widening will also be required from the City of Menlo Park, and Menlo Park may as a practical matter impose this mitigation measure through its independent authority over the project. The Council does not recommend that the City of Menlo Park adopt this measure for the reasons stated above. 11 970702 lac 0031590 • • 4.3-5 Implementation of the proposed projects could result in damaging effects on the Stanford Convalescent Some Gates. Mitigation measure 4.3-5(b) provides that if preservation of the stone entry gate pillars in their current location is not feasible, the gates shall be moved on the site and incorporated into the project's landscape plan. This measure has been adopted in conjunction with approvals granted for the Stanford West Senior Housing project. The Council finds that adoption. of this mitigation measure will lessen the project's impact on the historically valuable stone gate pillars to a less than significant level. This measure will preserve the gates on the site to permit continued public recognition of the entryway and to maintain their historic feeling and association within the project area. The Council finds that preservation of the gates in their current location is not necessary to mitigate this impact. Reiected Mitigation Measures The EIR also proposed an alternate mitigation measure 4.3-5(a) which has not been adopted by the City. Mitigation measure 4.3-5(a) would require redesign of the entry to the Stanford West Senior Housing Health Care Center and Ronald McDonald House to permit the Stone Entry Gates to be preserved where they are presently situated. The Council finds that this mitigation measure is infeasible because it would unnecessarily disrupt site plans for the Stanford West Senior Housing project, potentially resulting in loss of additional trees and increased visual impacts from relocation of access ways. The gates were not part of the original Stanford estate and have been relocated from their original location near El Camino Real to their current location. While the presence of the gates are considered to be an important reflection of the area's history, their location is not considered to be historically significant. The alternate mitigation measure 4.3-5(b) prescribed in the EIR has been adopted instead and will provide for preservation of the pillars on the site by incorporation into the landscape plans for the site and will avoid any significant adverse impact. 4.3-6 The proposed projects, in conjunction with other cumulative development projects in the San Francisquito Creek drainage, could result in damage or destruction of important prehistoric and historic cultural resources. Mitigation measure 4.3-6 recommends that all planning jurisdictions within the San Francisquito Creek drainage implement cultural resource testing and data recovery measures, similar to those described in mitigation measure 4.3-1 for projects involving development of sensitive cultural resource sites. 12 970702 lac 0031590 • • The Council has adopted the recommended mitigation measures for the SHRE/RRI project and all other approved Sand Hill Corridor projects. The Council finds that adoption of the recommended project -specific measures will lessen the project's contribution to the identified cumulative impacts to a less than significant level and will also lessen the cumulative impact of the Sand Hill Corridor projects collectively to a less than significant level. Adoption of the recommended mitigation measures with respect to future development projects within the City is beyond the scope of approvals granted for the project; however, the Council finds that such measures can and should be considered in conjunction with any future projects within the City. With respect to cumulative impacts from future development projects outside of the City, the Council finds that implementation of the recommended measures is within the jurisdiction and responsibility of other public agencies and that the agencies can and should implement such measures to the extent feasible. Because the nature and extent of potential cumulative impact from future projects on archaeological resources is presently —speculative 7 y.- -specu t- 1 and unknown, r.�...��..,..iY ot,ca.uia�.�.vc and- and because the extent to which other agencies can and will implement the recommended measures is presently unknown, the Council cannot determine at this time the extent to which the recommended. measures will be implemented or the extent to which these measures, if implemented, will lessen or avoid potential cumulative visual impacts. The Council therefore finds that this cumulative impact remains potentially significant despite the adoption of available mitigation measures by the City. 4.4 TRANSPORTATION Public Transit Service Impacts 4.4-1 Public transit service could be affected by development of the proposed projects. Mitigation measure 4.4-1(a) requires that a new transit bus passenger transfer and layover area(s) be located at a site acceptable to Santa Clara Transportation Authority, SamTrans and the City. The site will be located so that transit passenger access to the Stanford Shopping Center will not be degraded, and, if possible, improved. This measure may be implemented by locating new facility near the Shopping Center, or by modifying routes that currently use the transfer facility to include a stop close to the Shopping Center. Mitigation measure 4.4 -1(c) -requires that all new, relocated, and removed transit stops and pullouts shall be incorporated into a transit plan reviewed and approved by the City, SCCTA, and SamTrans. The Council finds that adoption of these mitigation measures will lessen the identified impact to a less than significant level. The EIR determined that the only potentially significant impacts of the project on public transportationresultfrom relocation or 13 97mn2 .:. 001590 • s potential loss of transit stops and facilities. By requiring replacement and possible improvement of the existing transfer and layover area serving the Stanford Shopping Center, and requiring review and approval by qualified transportation professionals of the relocation of any other transit facilities affected by the project, the adopted mitigation measures will avoid any reduction in passenger access to the Stanford Shopping Center or any other area affected by the project, and could result in improved access. The conditions of approval of the project also incorporate mitigation measures 4.4-1(b) and 4.4-1(d). Mitigation measure 4.4-1(b) requires the applicant to provide Marguerite service to the Sand Hill Road Corridor development project sites at a frequency and capacity integrated with other residential and employment sites served by the system. Mitigation measure 4.4-1(d) requires the applicant to operate an on -call passenger shuttle service to and from the Stanford West Senior Housing project. The Council finds that the addition of the Marguerite shuttle service to the Senior Housing project site will render the on -call shuttle unnecessary, and the Council, therefore, will not require that this additional measure be implemented_. - Although the EIR did not conclude that the project would adversely affect the availability of transit services to the Stanford West Apartments or Stanford West Senior Housing, these mitigation measures will enhance the availability of transportation services to ,these projects, improving the overall functionality of the transportation system served by the Sand Hill Road Extension and Related Roadway Improvements. Bicycle and Pedestrian Impacts 4.4-2 Bicycle and/or pedestrian access and safety could be affected by development of the proposed projects. Mitigation measure 4.4-2(b) requires that Class II bike lanes be provided on those portions of Sand Hill Road, Arboretum Road, Vineyard Lane, Pasteur Drive, Stock Farm Road, and Quarry Road which will be modified or reconstructed as part of the project. The bike lanes shall meet City of Palo Alto design requirements as designated by the Chief Transportation Official. Mitigation measure 4.4-2(c) requires that appropriate pedestrian and bicycle crossing devices and markings be provided at all signalized intersections modified or reconstructed as part of the project. All devices and markings shall meet applicable design standards in their respective jurisdiction. Americans With Disabilities Act (ADA) design standards shall be observed at all pedestrian crossings created or modified by the proposed projects. Mitigation measure 4.4-2(d) requires the applicant to provide a bicycle and pedestrian actuated crossing phase of El Camino Real on the north side of the proposed Sand Hill Road intersection, if the City Chief Transportation Official determines that the measure is feasible and will not have unacceptable effects on intersection vehicular level of service. 14 970702 lac 0031590 Mitigation measure 4.4-2(e) provides that for five years following project construction, the project applicant will fund an annual review of reported traffic accident data at the Sand Hill Road/I-280 interchange to determine whether a significant increase in bicycle/auto conflicts has occurred. If an increase is documented, the applicant will work with Caltrans, the City of Menlo Park and San Mateo County to design and obtain funding for safety improvements required to minimize these conflicts. Mitigation measure 4.4-2(f) requires that bicycle and pedestrian facilities be constructed at the intersection of Sand Hill Road/Santa Cruz Avenue and Junipero Serra Blvd./Alpine Road. The proposed design will be reviewed and approved by the City of Menlo Park Transportation Manager. The Council finds that adoption of these measures will avoid the project's potential adverse impacts on pedestrian and bicycle travel and will in fact improve and enhance safe bicycle and pedestrian travel in the- project area. The adopted mitigation measures, together with elements included in -the project, will extend bike lanes constructed to accepted safety standards along the full length of Sand Hill Road affected by the project. The adopted mitigation measures will also ensure construction of safe and adequate pedestrian and bicycle crossings of all major roadways affected by the project, thus actually improving existing conditions for bicycle and pedestrian travel in the project area. Mitigation measure 4.4-2(f) also requires that adequate bicycle and pedestrian crossings be constructed at the Sand Hill Road/Santa Cruz Avenue and Junipero Serra Blvd./Alpine Road intersections. Mitigation measure 4.4-2(e) further requires the applicant to work with responsible agencies to eliminate safety problems resulting from increased bicycle and vehicle traffic at the Sand Hill Road/I-280 intersection if such problems are determined to exist in the future. The Council recognizes that jurisdiction and responsibility for implementation of these mitigation measures in areas beyond the City's boundaries is vested in the City of Menlo Park. Approvals for some intersection improvements may also be required from the County of San Mateo and County of Santa Clara. The Council finds that Menlo Park can and should adopt and implement the recommended mitigation measures, but also recognizes that in the event that Menlo Park does not approve elements of the SHRE/RRI project within its jurisdiction or does not otherwise allow implementation of the recommended mitigation measures, potentially significant adverse impacts on pedestrian and vehicle travel could result along portions of Sand Hill Road and intersections outside the City's jurisdiction due to increases in traffic in these areas resulting from the Sand Hill Corridor projects. 15 970702 lac 0031590 • • 4.4-7 Development of the proposed projects could degrade the level of service of study area intersections, and contribute to increased intersection delay. The EIR concluded that the SHRE/RRI project overall will result in substantial benefits for local and regional traffic circulation, but that changes in traffic travel patterns related to the project and increases in traffic from the Sand Hill Road Corridor projects collectively will result in significant adverse changes in traffic conditions at a total of seven area intersections, specifically: Arboretum Road/Galvez Street - El Camino Real/Page Mill Road El Camino Real/Ravenswood Avenue El Camino Real/Valparaiso Avenue/Glenwood Avenue Junipero Serra Blvd./Alpine Road/Santa Cruz Avenue - Middlefield Road/Willow Road - Sand Hill Road/Santa Cruz Avenue The SHRE/RRI project alone, however, would have significant adverse impacts on traffic levels at only four area intersections, specifically: - Arboretum Road/Galvez Street - El Camino Real/Page Mill Road - Middlefield Road/Willow Road - Sand Hill Road/Santa Cruz. Avenue The conditions of approval require the applicant to contribute to all of the following mitigation measures to lessen these impacts and other impacts of the Sand Hill Corridor projects. Arboretum Road/Galvez Street: Mitigation measure 4.4-7(a) requires the applicant to install a traffic signal or other appropriate traffic control device(s) at the intersection of Arboretum Road/Galvez Street, and pay the full cost of these improvements. This measure shall be implemented when the intersection satisfies appropriate signal warrants as determined by the Chief Transportation Official. In the event that the City and the applicant determine that use of a traffic circle or "roundabout" will provide for the same or better LOS and safety as a traffic signal, the traffic circle may be constructed at the applicant's expense instead of a traffic signals or other traditional traffic control device(s). El Camino Real/Page Mill Road: Mitigation measure 4.4-7(b) requires the applicant to contribute a fair share of the costs of the following planned improvements: Add a southbound right turn lane; Add a westbound right turn lane; 16 970702 lac 0031590 Add a northbound right turn lane; and Extend the westbound left turn lane by 100 feet. These measures should be implemented -when the intersection approaches LOS F, as evaluated through periodic monitoring to be carried out by the applicant on behalf of the City. Sand Hill Road/Santa Cruz Avenue: Mitigation measure 4.4-7(c) requires the applicant to pay a fair share of the costs of the following improvements to the following improvements to the Sand Hill Road/Santa Cruz Avenue intersection: Widen Sand Hill Road to add second eastbound left turn lane; Widen Sand Hill Road to add second westbound left turn lane; Modify signal phasing; Install an exclusive right turn lane on the northbound approach of Santa Cruz Avenue; and Provide dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. The applicant shall also pay the costs of installing an exclusive right turn lane on the northbound approach of Santa Cruz Avenue and providing dual left turn lanes on both the northbound and southbound Santa Cruz Avenue approaches. Conditions 1.c and 12 of the project conditions of approval provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, with respect to any improvements in that jurisdiction, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share (subject to limitations based on engineering cost estimates) based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue: Mitigation measure 4.4-7(d) requires the applicant to pay a fair share of the costs of the following improvements to the Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue intersection mandated by the Menlo Park General Plan or recommended in the EIR: Widen northbound approach to add exclusive right turn lane; Install an additional southbound left -turn lane. 17 970702 lac 0031590 Conditions 1.c and 12 of the project conditions of approval provide that the applicant shall advance funds to pay the full costs of these improvements if the City of Menlo Park and/or the County of San Mateo, as applicable, enters into an agreement to reimburse the applicant for costs in excess of its fair share. If no reimbursement agreement is adopted, the applicant shall pay its fair share (subject to limitations based on engineering cost estimates) based on traffic attributable to the Sand Hill Corridor projects. Implementation of this mitigation measure will not occur until approvals are obtained from the City of Menlo Park and/or the County of San Mateo, as applicable. Middlefield Avenue/Willow Road: Mitigation measure 4.4-7(e), identifies a number of improvements which would be necessary to mitigate cumulative traffic impacts at this intersection, including the following: Add a second southbound left turning lane. Restripe eastbound approach. Modify signal phasing, including a leading left turn phase in the signal phasing for the north and south directions. The timing of these improvements will be determined by the City of Menlo Park, through periodic monitoring and/or through subsequent environmental impact analysis and documentation. Condition l.f of the project conditions of approval partially implements this mitigation measure by requiring that the applicant shall either make signal timing improvements sufficient to return traffic levels of service at this intersection to level of service D, or contribute its fair share of the costs to construct -the recommended intersection improvements. This obligation would not be triggered until current level of service falls to E or worse. Sand Hill Road/Santa Cruz Avenue. and Junipero Serra Blvd.1Alpine Road: Mitigation measure 4.4-7(h) provides that the applicant shall conduct an operational analysis of the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections to identify the appropriate combination of roadway and traffic signal improvements necessary to improve operation to LOS D during peak hours, if feasible. The EIR also recommends that the following mitigation measures be implemented to mitigate cumulative traffic impacts at specified intersections within the City of Menlo Park, but does not provide for direct participation by the applicant in implementation of these mitigation measures. El Camino Real/Ravenswood Avenue: Mitigation measure 4.4-7(f) recommends that the following improvements to the El Camino Real/Ravenswood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: 18 - 970702 lac 0031590 - Widen northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. - Widen westbound approach to add exclusive right turn lane. El Camino Real/Valparaiso Avenue/Glenwood Avenue: Mitigation measure 4.4-7(g) recommends that the following improvements to the El Camino Real/Valparaiso Avenue/Glenwood Avenue intersection be completed as prescribed in the City of Menlo Park's general plan: Restripe northbound approach to add third northbound through lane. Restripe southbound approach to add third southbound through lane. - Widen westbound approach lane. to add exclusive right turn - Final design shall Include provisions for traffic. bicycle In addition, the EIR recommends that signal phasing at this intersection be modified to include split phasing in the east/west direction and a leading left turn phase in the north/south direction. The Council finds that these adopted mitigation measures, if implemented, will lessen the project's impacts on traffic at the four significantly affected intersections to a less than significant level, and will also substantially lessen the impact of the project's contribution to cumulative traffic at other intersections significantly affected by the Sand Hill Corridor projects collectively. Mitigation measures 4.4 -7(a) -(e) require the applicant to pay all or a fair share of the costs of physical improvements necessary to enable each of these affected intersections to serve anticipated cumulative traffic demands at acceptable levels of service. Mitigation measure 4.4-7(h) also provides for identification of appropriate additional intersection improvements should the City of Menlo Park elect to achieve a higher level of service at the Sand Hill Road/Santa Cruz Avenue and Alpine Road/Junipero Serra Boulevard intersections. The Council recognizes that final authority to approve those portions of the SHRE/RRI project located outside the City, and to approve and implement the identified mitigation measures at three of the four intersections significantly affected by the project, is vested in public agencies other than the City, specifically the City of Menlo Park (Sand Hill Road widening and related improvements in Menlo Park, mitigation measure 4.4-7(c), Sand Hill Road/Santa Cruz Avenue and mitigation measure 4.4-7(e), Middlefield Avenue/Willow Road); 19 970702 !ac 0031590 • • County of Santa Clara {mitigation measure 4.4-7(a), Arboretum Road/Galvez Street intersection); and the County of San Mateo (mitigation measure 4.4-7(c), Sand Hill Road/Santa Cruz Avenue intersection). Responsibility and authority for implementing the recommended mitigation measures at the additional intersections cumulatively impacted by the project is also vested in other public agencies, specifically the City of Menlo Park (mitigation measures 4.4-7(f), El Camino Real/Ravenswood Avenue, and 4.4-7(g), El Camino Real/Valparaiso Avenue/Glenwood Avenue) and 4.4-7(d) Junipero Serra Boulevard/Alpine Road/Santa Cruz Avenue). The Council finds that the identified mitigation measures can and should be approved and implemented by these agencies. However, the Council also recognizes that in the event that portions of the project located the City of Menlo Park are not approved or that if one or more of the listed mitigation measures are not approved and implemented by the appropriate responsible agencies, the project will result in significant adverse impacts on the Arboretum Road/Galvez Street, Middlefield Road/Willow Road and/or Sand Hill Road/Santa Cruz Avenue intersection(s), and will contribute to significant impacts at other intersections cumulatively affected by the Sand Hill Corridor projects. Because it cannot presently be determined if or when the appropriate mitigation measures will be implemented by the respective responsible agencies, these impacts are considered by the Council to be potentially significant. 4.4-8 Construction activities could lead to both temporary disruption of transportation system operation, as well as to permanent damage to elements of the system such as pavement and bridges. Mitigation measure 4.4-8(a) requires the applicant to provide adequate off-street parking for all construction -related vehicles throughout the construction period. If adequate parking cannot be provided on the construction sites, a satellite parking area shall be designated, and a shuttle bus shall be operated to transfer construction workers to the job sites. Mitigation measure 4.4-8(b) provides that construction activities related to the project are prohibited from substantially limiting pedestrian access (e.g, by blocking pedestrian routes), without prior approval from the City of Palo Alto and/or Caltrans. Any approval shall require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4-4.8(c) provides that the applicant shall be prohibited from limiting bicycle access (e.g. by blocking or restricting existing routes) while constructing the project, without prior approval from the City of Palo Alto and/or Caltrans or the City of Menlo Park (depending upon the jurisdiction of the requested action). Any approval will require submittal and approval of specific construction management plans to mitigate the specific impacts to a less -than -significant level. 20 970702 lac 0031590 Mitigation measure 4.4-8(d) provides that the applicant shall be required to prohibit or limit the number of construction material deliveries from 7 a.m. to 9 a.m., and from 4 p.m. to 6 p.m. on weekdays. Mitigation measure 4.4-8(e) provides that the applicant shall be required to prohibit or limit the number of construction employees from arriving or departing the site from the hours of 4:30 p.m. to 6 p.m. Mitigation measure 4.4-8(f) requires that all construction -related equipment and materials shall be delivered and removed on truck routes designated by the cities of Palo Alto and Menlo Park. Heavy construction vehicles shall be prohibited from accessing the sites from other routes. Mitigation measure 4.4-8(g) requires the applicant to repair any structural damage to public roadways, returning any damaged sections to original structural condition. The effectiveness of this measure shall be guaranteed by requiring surveys of road conditions before and after construction. Mitigation measure 4.4-8(h) prohibits the applicant from limiting access to public transit (e.g. by relocating or restricting access to bus stops or transfer facilities), and from limiting movement of public transit vehicles, without prior approval from the Santa Clara Transit Agency or other appropriate jurisdiction. Any approval will require submittal of specific construction management plans to mitigate the specific impacts to a less -than -significant level. Mitigation measure 4.4-8(I) provides that in lieu of mitigation measures 4.4-8(a) through (h), the project applicant may prepare detailed construction impact mitigation plans for approval by the Cit, of Palo Alto Chief Transportation Official and City of Menlo Park Transportation Manager prior to commencing any construction activities with potential transportation impacts. The plan must address all aspects of construction traffic management necessary to eliminate or reduce transportation impacts to acceptable levels. Mitigation measure 4.4-8(k) requires the applicant to identify and implement measures to ensure that construction activities do not reduce roadway capacity during major athletic events or other special events involving substantial numbers of visitors to the campus. This measure may be implemented by requiring special supplemental permits for Stanford -sponsored events during significant construction periods, or by other means. The Council finds that adoption of these measures will lessen the project's potential construction phase traffic and transportation impacts to a less than significant level. These measures provide for comprehensive planning for construction traffic and establish standards, criteria and implementing measures which will ensure that significant interference with vehicle, 21 970702 tax 0031590 bicycle, pedestrian and emergency vehicle access is avoided during all phases of construction. Project Areas Outside the City Adoption and implementation of the applicable recommended measures on portions of the project outside the City is within -the jurisdiction and responsibility of other public agencies, primarily the City of Menlo Park. The Council finds that the recommended mitigation measures can and should be adopted in the event that approvals are granted for those portions of the project outside the City. The Council also recognizes, however, that in the event that Menlo Park approves the project but does not implement the recommended mitigation measures, significant adverse impacts could result. 4,5 AIR QUALITY 4.5-1 The Milo generated during the construction of the proposed projects could be harmful to nearby pollutant -sensitive land uses. Mitigation measure 4.5-1 requires the applicant to implement a construction phase program which includes the following measures to reduce generation of particulate matter on the project site during construction: Water all active construction areas at least twice a day, or as needed to prevent visible dust plumes from blowing off -site. Use tarpaulins or other effective covers for on -site storage piles and for haul trucks on public streets. Pave, apply water three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas during construction. Sweep all paved access routes, parking areas, and staging areas daily (preferably with water sweepers). Sweep streets daily (preferably with water sweepers) if visible amounts of soil material is carried onto public streets. If the working area of any construction site exceeds four acres at any one time, implement the following additional measures: Apply (non-toxic) soil stabilizers to inactive construction areas. Enclose, cover, water twice daily, or apply (non-toxic) soil binders to exposed stockpiles. Limit construction site vehicle speed to 15 mph on unpaved areas. 22 970702 lac 0031590 Replant vegetation in disturbed areas as quickly as possible. If the working area of any construction site is located near any sensitive receptors, implement the following measures in addition to those listed above: Suspend excavation and grading activity when winds exceed 25 mph. The last mitigation would be applicable to the Sand Hill Road widening where it passes the 14 single family homes in Menlo Park between Santa Cruz Avenue and Oak Avenue. The Council finds that adoption of this measure will lessen the identified potential adverse impact from construction phase dust and particulate matter to a less than significant level. Implementation of twice daily watering has been shown to reduce construction site PM,0 emissions by at least 50 percent. This practice, in conjunction with the other listed measures, will reduce PM10 emissions during construction to less than the BAAQMD threshold of significance of 80 lbs/day for all anticipated construction activity. Project Areas Outside the City Adoption and implementation of the applicable recommended measures on portions of the project outside the City is within the jurisdiction and responsibility of other public agencies, primarily the City of Menlo Park. The Council finds that the recommended mitigation measures can and should be adopted in the event that approvals are granted for those portions of the project outside the City. The Council also recognizes, however, that in the event that Menlo Park approves the project but does not implement the recommended mitigation measures, significant adverse impacts could result. 4.5-2 ROG, NOx, and PMWW emissions generated by motor vehicles and residential stationary sources associated with the proposed projects would exceed the 80 lbs/day threshold and could hinder regional and local attainment of State ozone and 14410 standards. Mitigation measure 4.5-2(a) requires the City to implement mitigation measure 4.4-2(a), which provides that final design for bicycle and pedestrian circulation within the Stanford West Apartments and Senior Housing sites shall be reviewed to ensure the circulation system will function as a part of regional or inter -city bicycle and pedestrian connections, thereby promoting increased use of bicycles or pedestrian travel by area residents. Mitigation measure 4.5-2(c) requires the City to implement mitigation measure 4.4-1, discussed above. The EIR concludes that the project will have no significant adverse effect on air pollution emissions, but that the Sand Hill 23 970702 lac 0031590 Road Corridor projects collectively would produce emissions which would exceed EAAQMD thresholds of significance. The Council finds that this cumulative air quality impact is significant. 4.5-4 Cumulative daily traffic along major roadways in the project and study areas would emit more NOx, and Pit with the implementation of the Sand Hill Road Projects, but emissions of ROG would decrease. The EIR found that the Sand Hill Road Corridor projects, would collectively contribute to significant cumulative increases of emissions of NOx and PM/0 in the project area, but that the SHRE/RRI project, by improving traffic capacity and service, and reducing congestion and delays in the project area, would actually decrease total anticipated emissions of NOx by 38 lbs per day and emissions of ROG by 249 lbs per day, thus resulting in a beneficial net air quality impact. The project will also result in a less -than -significant contribution of 56 lbs/day of PM/0 to cumulative PM/0 emissions. The EIR did not identify any feasible mitigation measures for reducing cumulative air quality impacts associated with other development and cumulative traffic increases in the project area. Cumulative traffic -related air pollution emissions are regulated through means beyond the City's jurisdiction and control. Individual vehicle emissions and automotive fuels are subject to regulation only by state or federal government. Regional traffic levels are also heavily influenced by past and future planning and land use decisions over which the City has no control. The Council therefore finds that no additional feasible mitigation measures are presently available to the City to mitigate this cumulative impact, due to increases in regional traffic, and legal authority and responsibility, if any, for feasible mitigation measures is vested in other agencies beyond the City's control. The Council therefore finds that the identified cumulative impact is significant. 4.6 NOISE 4.6-1 The noise generated during the construction of the proposed projects could be disruptive to nearby noise -sensitive land uses. Mitigation measure 4.6-1(a) provides that construction activities will be limited to the hours of 8:00 a.m. to 8:00 p.m. Monday through Friday, and if weekend work is necessary, to the hours of 9:00 a.m. to 8:00 p.m. on Saturday, and to the hours of 10:00 a.m. to 6:00 p.m. on Sunday. Mi.ication measure 4.6-1(b) provides that construction equipment shall be outfitted and maintained with noise reduction devices (i.e., mufflers, enclosures for stationary equipment, etc.) to obtain at least an average 10 dBA reduction shown feasible in Table 4.6-5. 24 970702 !ac 0031590 Mitigation measure 4.6-1(c) provides that stationary noise sources (e.g., compressors, concrete mixers, etc.) shall be located on portions of the sites furthest away from residential and other noise -sensitive areas, and that acoustic shielding shall be used with such equipment. The Council finds that adoption of these measures will substantially lessen construction phase noise impacts on surrounding residents and visitors within the City, but will not reduce these impacts to less than significant levels. The measures will reduce noise generated by construction activities and will eliminate construction noise during normal sleeping hours. However, significant noise impacts will remain due to inherent noise generated by large scale construction activity and heavy equipment. Project Areas Outside the City With respect to those portions of the project located beyond the City's boundaries, the EIR recommends the adoption of the above mitigation measures 4.6-1(a), (b) and (c) and also recommends the following additional measure: Mitigation measure 4.6-1(d) provides that where construction of Sand Hill Road requires work in the road segment fronted by homes between Oak and Santa Cruz Avenues, temporary noise barriers shall be erected to protect the residents. The Council finds that the adoption and implementation of these measures outside the City of Palo Alto's boundaries is within the jurisdiction and responsibility of other public agencies, primarily the City of Menlo Park, and that these mitigation measures can and should be adopted by the responsible agency in the event that approvals are granted for those portions of the project located within the respective jurisdictions of these agencies. The Council also recognizes, however, that in the event that these responsible agencies approve the project but do not implement the recommended mitigation measures, significant adverse nurse impacts would result. 4.6-3 Traffic generated by the proposed projects and other cumulative developments and the traffic accommodated by the proposed roadway improvements would impact existing and proposed residential and other sensitive land uses adjacent to roadways in the project and study areas. Mitigation measure 4.6-3(b) requires the applicant to construct a landscaped buffer strip with at least a 3 -foot -high berm along Sand Hill Road between Stanford Avenue and Oak Avenue in conjunction with implementation of the Sand Hill Road widening and realignment between Santa Cruz and Oak Avenues. Mitigation measure 4.6-3(c) requires the applicant to construct a soundwall 6 feet high or higher between Santa Cruz Avenue and Stanford Avenue in conjunction with implementation of 25 970702 lac 0031590 the Sand Hill Road widening to reduce noise from traffic increases at the nearby intersection. Mitigation measure 4.6-3(d), as modified by Condition l.g of the project conditions of approval, requires the applicant to monitor noise increases in residences in the designated areas along Sand Hill Road where the Sand Hill Road Corridor projects may be responsible for more than 50% of potential increases in traffic -related noise. If noise increases are detected, the applicant shall be responsible for the costs of measures such as additional insulation, double -glazed windows, or individual soundwalls as determined necessary by acoustic study to return interior noise levels in these residences to pre -project levels or to 45 dBa. Residents may also contribute any further funds necessary to further reduce interior noise levels to acceptable levels. The Council finds that these mitigation measures, if implemented, will substantially lessen significant cumulative traffic -related noise impacts along the Sand Hill Road corridor although these measures will not necessarily reduce cumulative noise impacts to a less than significant level for every residence affected by the project. Mitigation measure 4.6-3(d) provides for a fair share contribution by the applicant to the costs of physically upgrading affected residences with noise mitigation measures. Mitigation measures 4.6-3(b) and 4.6-3(c) provide for construction of physical barriers to reduce noise to acceptable levels at protected residences. The adopted mitigation measure 4.3-6(d) will impose responsibility for necessary monitoring of actual noise increases on the applicant and also imposes responsibility on the applicant to pay.a share of actual mitigation costs in proportion to the applicant's responsibility for these impacts where the Sand Hill Corridor projects are the predominant cause of cumulative traffic -related noise impacts. The Council does not believe that the applicant can or equitably should be held responsible for more than a fair share of the costs of mitigating these potential cumulative noise impacts. Revisions made by the City to mitigation measure 4.3-6(d) are intended to strengthen the measure by fixing responsibility for noise monitoring on the applicant, and to also amend the -measure to provide that the applicant shall be financially responsible only for a fair share of the costs of implementing the mitigation measure. The Council recognizes that mitigation measure 4.6-3(d), as adopted, will not result in lessening of cumulative noise impacts at locations at which less than 50% of the cumulative traffic -related noise increase is attributable to the Sand Hill Corridor projects. The Council also recognizes that since implementation of mitigation measure 4.6-3(d) requires the cooperation of affected homeowners, the physical improvements necessary to reduce noise levels at some affected residences to acceptable levels may not be constructed by choice of the owner. The Council therefore recognizes that notwithstanding adoption of the identified mitigation measures, cumulative traffic -related noise impacts may remain significant for some residences affected by the projects. 26 9'70702 lac 0031590 • i With respect to mitigation measures 4.6-3(b) and 4.6-3(c), which will mitigate noise impacts on certain residences in Menlo Park, the Council further recognizes that although the conditions of approval require the applicant to accept responsibility for implementation of these mitigation measures, approval for implementation of these measures must be obtained from the City of Menlo Park. The Council finds that implementation of these mitigation measures can and should be approved by the City of Menlo Park. The Council also recognizes, however, that in the event that approval for implementation of these measures is not obtained from Menlo Park, affected residences in Menlo Park would experience significant cumulative traffic -related noise impacts due to increased cumulative traffic on Sand Hill Road. 4.7 BIOLOGICAL RESOURCES 4.7-1 Implementation of the proposed projects would result in loss of trees and associated wildlife habitat. Mitigation measure 4.7-1(a) requires that native trees removed for the projects shall be replaced .at a ratio of 3:1 on a per acre basis by the same species from locally collected stock, and provides for additional replanting if survival rates fall below 80 percent. Mitigation measure 4.7-1(b) requires that non-native landscape trees removed for the projects be replaced on a two -to -one basis. Mitigation measure 4.7-1(c) provides that the City shall contract with an independent arborist to (a) review plans to provide for maximum retention of trees and necessary additional tree protection measures; b) monitor project construction ; and c) recommend changes in the tree removal plan as necessary during construction. Mitigation measure 4.7-1(e) requires that all trees adjacent to project construction areas which are not removed will be avoided and protected according to specified procedures incorporated into all construction and/or demolition contracts. Mitigation measure 4.7-1(g) provides that native trees removed from natural riparian habitats shall be replaced in accordance with mitigation measure 4.7-1(a) in open space areas adjacent to San Francisquito Creek, either in portions of the abandoned golf course and temporary bridge construction disturbance areas, and/or adjacent to the Stanford West Apartments and Senior Housing sites. The Council finds that adoption of these measures will lessen the project's long and intermediate term impacts on trees and related wildlife habitat within the City's jurisdiction to less than significant levels. These measures will also substantially lessen but will not avoid significant adverse short term impacts (0-10 years) to trees and related wildlife habitat within the City's jurisdiction. These measures provide for protection of as many trees as possible during project construction and replacement 27 970702 lac 0031590 of all trees removed as a result of the project at a greater than 1-1 ratio. These mitigation measures will therefore eventually result in replacement of all trees and related habitat with new trees and habitat of equal or greater value. However, because it will take a number of years for replacement trees to reach a level of maturity similar to those being removed, there will be an unavoidable short-term decline in quality of trees and related habitat value in the project area as a result of the project. Project Areas Outside the City With respect to those portions of the project located outside the City's boundaries, the EIR recommended adoption of the above mitigation measures 4.7-4(a), (b), (c), (e) and (g) and also the following two additional measures: Mitigation measure 4.7-1(d) provides that mitigation for loss of the large coast live oak on the Stanford University golf course shall be determined by the City of Menlo Park in accordance with its ordinance governing removal of "heritage" trees. Mitigation measure 4.7-1(f) provides that the large elderberry tree near existing Tee # 4 of the Stanford University golf course shall be preserved, fenced and protected from construction impacts by following the recommendations in Mitigation Measure 4.7-1(d). These measures shall be accomplished as part of comprehensive riparian and oak woodland mitigation and monitoring program as specified under Mitigation Measure 4.7-3. The Council finds that adoption and implementation of these mitigation measures for elements of the project outside the City of Palo Alto's boundaries is within the jurisdiction and responsibility of other public agencies, specifically the City of Menlo Park and County of Santa Clara, and that these mitigation measures can and should be adopted by these public agencies in the event that approvals are granted for those portions of the project located within the respective jurisdictions of these agencies. The Council recognizes, however, that in the event these mitigation measures are not adopted by the responsible agencies, significant adverse impacts will result. 4.7-2 Construction of the proposed projects would result in tree removals that could directly destroy nests, eggs and immature birds, and would remove future nesting habitat for birds, including sensitive species such as raptors and migrating songbirds. Mitigation measure 4.7-2(a) provides that in order to avoid the nesting season of raptors and sensitive songbirds, tree removals shall not take place between February 15 and June 30, unless otherwise determined by the California Department of Fish and Game (CDFG) on a case -by -case basis. Mitigation measure 4.7-2(b) provides that if tree removal between January 1 and February 15 is required, a pre -construction survey shall be conducted to identify the presence, or lack 28 970702 lac 0031590 • • thereof, of nests of raptors. If nests are identified, CDFG shall be contacted and appropriate protocols for nest relocation shall be implemented. If relocation of occupied, viable nests is not feasible, construction shall be delayed and the tree left undisturbed until completion of nesting activity. Mitigation measure 4.7-2(c) requires implementation of mitigation measures 4.7 -1(a) -(f) and 4.7 -4(a) -(c) (tree replacement and riparian habitat replacement), discussed above. The Council finds that adoption of these measures will lessen the project's impacts on nesting birds within the City to a less than significant level. These measures will avoid any direct destruction of nests and provide for eventual -replacement or enhancement of all nesting habitat lost. While there will be a short term loss of nesting habitat for all bird species and short and intermediate term loss of nesting habitat for raptors, there are sufficient alternate nesting sites in the area that this impact will not have any significant adverse effect on overall nesting opportunities or on bird populations. Project Areas Outside the City With respect to those portions of the project located outside the City, the Council finds that the adoption and implementation of the foregoing mitigation measures is within the jurisdiction and responsibility of other public agencies, specifically the City of Menlo Park and County of Santa Clara, and that these mitigation measures can and should be adopted by these public agencies in the event that approvals are granted for those portions of the project located within the respective jurisdictions of these agencies. The Council recognizes, however, that in the event these mitigation measures are not adopted by the responsible agencies, significant adverse impacts will result. 4.7-4 The proposed widening of the Sand Hill Road Bridge would result in loss of riparian vegetation and associated habitat values and would encroach urban development closer to the San Francisquito Creek corridor. Mitigation measure 4.7-4(a) requires that removal of riparian vegetation during construction shall be confined to the minimal area necessary and specifies additional measures to protect habitat values, including Compliance with mitigation measure 4.7-1; Plans to minimize impacts to riparian habitats from bridge construction shall be prepared to the satisfaction of a creek restoration specialist. Replacement of wing walls with crib walls or large rocks/boulders that would allow planting of native riparian shrubs and trees will be considered; 29 970702 lac 0031590 • • Construction staging areas and access roads shall be located away from sensitive riparian habitats to the extent practicable; - Damage to riparian trees shall be minimized by installing temporary barrier fencing; - No disturbance will be allowed within the drip lines of trees to be avoided; No fencing, signs, electrical lines, etc. shall be attached to existing trees; The project shall avoid an unusually large blue elderberry adjacent to the Stanford University Golf Course Hole #4; [The project plans indicate that the elderberry would be avoided.) Recommendations in the arborist's report to avoid damage to tree roots shall be implemented. Mitigation measure 4.7-4(b) provides for preparation and implementation of a detailed mitigation plan where removal of riparian vegetation cannot be avoided. The mitigation plan shall provide for replacement of riparian trees, understory shrubs,' and habitat values caused by construction of the new bridge and shall be developed in consultation with CDFG. Additional creek restoration measures will be developed as appropriate in coordination with CDFG, Coyote Creek Riparian Station (CCRS), and Coordinated Resource Management and Planning (CRMP) to allow for increased structural diversity in the channel through strategic placement of logs and other natural features. A general clean-up of the creek and bank stabilization and erosion control efforts should be included. A maintenance clan for temporary irrigation of plantings and control of non-native plant species shall be developed. This plan shall include minimum performance criteria of 801 for survivability at the end of a minimum 5 -year period. Plant materials used in mitigation shall be confined to California native species propagated from seeds or cuttings collected in the riparian corridor of San Francisquito Creek. Mitigation measure 4.7-4(c) Sand Hill Road shall be realigned up to 40 feet southwards to more closely coincide with the bounds of the existing Stanford Shopping Center parking lot where it approaches El Camino Real. The Council finds that adoption of these measures will lessen the project's impacts on riparian habitat to a less than significant level. The adopted mitigation measures provide for a number of specific measures to avoid impacts on riparian habitat to the extent possible and provide for replacement and restoration of riparian habitat destroyed by construction activities. These measures will eliminate all significant impacts to the riparian habitat zone in the area of the Sand Hill Road extension. While permanent loss of a small area of riparian habitat in the area of 30 970702 lac 0031590 • • the Sand Hill Road bridge widening is unavoidable when this portion of the project is commenced, the adopted measures will reduce damage to a less than significant level by minimizing the amount of riparian habitat affected and providing for permanent restoration of all riparian habitat incidentally affected by construction activities. Project Areas Outside the City The Council recognizes that construction of the San Francisquito bridge widening will require approval from the City of Menlo Park and that approval and full implementation of the recommended mitigation measures will also require approval and cooperation of the City of Menlo Park. The Council finds that in the event that the City of Menlo Park grants necessary approvals for the bridge widening, Menlo Park can and should adopt the recommended mitigation measures. In the event, however, that necessary approvals for the bridge widening are not granted by Menlo Park, or that Menlo Park declines to approve or permit the implementation of the above mitigation measures which have been made conditions of the City of Palo Alto's approval of the project, the bridge widening will not be authorized to proceed by the City and the identified potentially significant impacts of the bridge widening on riparian habitat will not occur. 4.7-5 Construction -related noise and human activity for the proposed projects could create impacts to native wildlife species. Mitigation measure 4.7-5 prohibits construction activities within 50 -feet of riparian habitats along San Francisquito Creek during the nesting season (February.15 - June 30), unless otherwise determined on a case -by -case basis by the CDFG. The Council finds that adoption of these measures will lessen the project's potential noise and disturbance impacts on wildlife to a less than significant level. This potential impact will occur only in the area of the San Francisquito Creek bridge widening. The adopted mitigation measure will ensure that construction activity does not disrupt mating or nesting activities of birds in this area. While some temporary disruption of movement or feeding activities of other species may occur in this area during allowed construction period, this temporary disturbance will not be sufficient to have any long-term effects, such as loss of feeding or mating opportunities, on species or individuals within the area. Project Areas Outside the City The Council recognizes that approval for the bridge widening project must also be obtained from the City of Menlo Park and that adoption of the recommended mitigation measures for construction activities within Menlo Park is within the responsibility and authority of Menlo Park. The Council finds that in the event that Menlo Park grants approval for the bridge widening, Menlo Park can and should adopt the recommended mitigation measure. However, because the timing of construction activities for the bridge 31 970702 lac 6031590
