HomeMy WebLinkAboutStaff Report 418-06FROM: City Manager’s Report CITY MANAGER DEPARTMENT: PLANNING & COMMUNITY ENVIRONMENT DATE: SUBJECT: NOVEMBER 20, 2006 CMR: 418:06 195 PAGE MILL ROAD, 2825, 2865, 2873, 2891 & 2901 PARK BOULEVARD [05PLN-00281]: APPEAL BY COURTHOUSE PLAZA COMPANY OF THE DIRECTOR OF PLANNING AND COMMUNITY ENVIRONMENT’S DENIAL OF A MAJOR ARCHITECTURAL REVIEW BOARD APPLICATION TO ALLOW THE CONSTRUCTION OF A THREE STORY BUILDING TO INCLUDE 50,467 SQUARE FEET FOR RESEARCH AND DEVELOPMENT SPACE ON THE GROUND FLOOR AND 104,971 SQUARE FEET FOR TWO FLOORS OF RESIDENTIAL APARTMENTS TOTALING 84 UNITS, PLUS A SUBTERRANEAN PARKING GARAGE AND RELATED SITE IMPROVEMENTS. THE PROJECT INCLUDES A REQUEST FOR DESIGN ENHANCEMENT EXCEPTIONS TO EXCEED THE MAXIMUM ALLOWABLE BUILDING HEIGHT, ENCROACH INTO THE SIDE AND REAR DAYLIGHT PLANE, REDUCE THE FRONT AND STREET SIDE SETBACKS AND INCREASE THE LOT COVERAGE. ENVIRONMENTAL REVIEW: A MITIGATED NEGATIVE DECLARATION HAS BEEN PREPARED. RECOMMENDATION Staff recommends that the City Council uphold the Director of Planning and Community Environment’s decision to deny the Major Architectural Review Board (ARB) application, finding that zoning ordinance requirements are not met, as outlined in the Draft Record of Land Use Action (Attachment A). BACKGROUND On October 16, 2006, the City Council considered whether to schedule an appeal by Courthouse Plaza of the Director of Planning and Community Environment’s denial of the project as described in the October 16, 2006 City Manager’s Report (Attachment E). The Council removed the item from the Consent Calendar and scheduled it for a public heating so that the Council can more fully consider the project prior to action on the application. Project Histor7 Development proposals and applicable regulations for this site over the past two years are outlined below: CMR: 418:06 Page 1 of 6 September 30, 2004 - City Council denied a Planned Community (PC) application for a four-story, research and development and residential mixed use building, including 45,115 square feet of research and development space and 2,000 square feet of retail on the ground floor, three levels of residential apartments totaling 177 units, and subterranean parking. July 7, 2005 - Architectural Review Board (ARB) reviewed a Preliminary Major ARB application by the applicant of the revised project for 84 residential units and 50,467 square feet of nonresidential development. The project was subject to GM(B) regulations in effect at the time. August 4, 2005 - Application by Courthouse Plaza Company for major ARB review of the revised project. October 11, 2005 - City Council revised the zoning ordinance to remove the "B" overlay from the General Manufacturing (GM) zone district and to prohibit all housing and mixed-use (residential and nonresidential) development as permitted uses. However the Council allowed this project to proceed under the GM(B) zoning since it was submitted prior to the zone change. September 7, 2006 - ARB recommended approval of the project with conditions to the Director of Planning and Community Environment, with regard only to project design, not zoning compliance (pursuant to GM zoning, as requested by the applicant). September 11, 2006 - City Council adopted the Pedestrian and Transit Oriented Development (PTOD) Combining District. The PTOD regulations became effective on October 10, 2006. September 15, 2006 - The Director of Planning and Community Environment denied the project based on noncompliance with zoning criteria (Attachment D). September 27, 2006 - Director’s decision appealed by the applicant. October 16, 2006 - Appeal request considered by the Council. Council removed the item from the Consent Calendar and scheduled it for a public hearing. More detailed background information and discussion of project issues are found in the October 16, 2006 CMR (Attachment E). DISCUSSION The staff’s recommendation for denial of the project is based on noncompliance with the following zoning provisions: Mixed use development (research and development w/residential) is not permitted in the GM (General Manufacturing) zone district. CMR: 418:06 Page 2 of 6 The project exceeds the allowable Floor Area Ratio (FAR) permissible within the GM zone district. Justification provided for the parking reduction request is insufficient. The Design Enhancement Exception findings for the requested exceptions from code regulations related to height, daylight plane, setbacks, and lot coverage are not supported by the project design. In particular, adequate transitions to Alma Street are not provided. The massing of the 451-foot long, 3-story wall should be mitigated with vertical relief and horizontal height variations. Also, the Park Boulevard frontage is not designed as a pedestrian-oriented fagade, i.e., with frequent door openings, awnings, and street furniture. Since housing is not a permitted use in the GM zone district, there are no residential development standards applicable to the proposed residential portion of the development. The project site was identified as a housing opporttmity site in the Housing Element of the Comprehensive Plan with an anticipated RM-40 zoning. Therefore, staff has applied RM-40 height, setback, coverage, and daylight plane criteria along with the base GM zoning developments standards to the project. The project would not conform with the development standards as depicted in Attachment B. Housing Law (Senate Bill 1818) The applicant has requested a development concession under Senate Bill 1818. This relatively new law requires cities to offer incentives or concessions to encourage the construction of affordable housing (allowances for mixed use, increased FAR or height, reductions in parking, setbacks, open space, etc.) based on the percentage of affordable units in a development. The law specifies that: One incentive or concession is to be granted for projects with at least 10 percent of the total units for lower income households; Two incentives or concessions are to be granted for projects that include at least 20 percent of the total units for lower income households; Three incentives or concessions are to be granted for projects that include at least 30 percent of the total units for lower income households. The project would include 17% of the total residential units as below market rate (BMR) units. Given the provisions of SB 1818, the applicant may be eligible for one concession based on the number of affordable housing units proposed. The applicant maintains that an allowance for mixed-use and additional floor area should be combined into one concession. It is the opinion of the City Attorney and Planning Director that separate concessions would be necessary for each, therefore requiring that at least 20 percent of the total units be set aside as affordable units for below income households. Additional concessions would be required for the parking reduction and the Design Enhancement Exceptions, unless they can be approved on their merits. Alternative Design Staff has met with the applicant, his architect, and his attorney to offer an alternative CMR: 418:06 Page 3 of 6 proposal that would not require compliance with Pedestrian Transit Oriented Development (PTOD) District regulations, but which would embody some of the PTOD design concepts for addressing building mass, transitions, and streetscape design. Such an alternative would also allow the City to approve the zoning in conjunction with SB 1818 provisions (20% BMR component). Similar suggestions have been offered by staff previously over the past year, but the applicant has chosen not to revise plans accordingly. Components of the alternative design include: ao Mixed-Use/Floor Area Ratio The project shall include 20% of the total number of residential units as below market rate units to qualify for two concessions (mixed use and FAR) pursuant to SB 1818. b°Request for Parking Reduction To justify the applicant’s request for the parking reduction, the following additional information shall be submitted for review and approval by staff prior to final ARB review and issuance of building permits: A parking study demonstrating time-of-day parking for the different land uses; as well as documenting that the reduced parking request is justified and that "shared" spaces will be available to accommodate the parking demand. A Transportation Demand Management Plan (TDM) program indicating measures to be implemented and enforced to encourage use of transit or other non-vehicular transportation modes for residents and employees of the site. Design and DEEs To address design concerns about the 451-foot long, 40-foot high wall along the Alma Street frontage and pedestrian-oriented streetscape design along Park Boulevard, the project shall be redesigned to include the following: The rear wall of the building is to be redesigned to conform to the PTOD daylight plane along the Caltrain right-of-way (16 foot height and 1:1 slope, see Attachment C diagrams). The rear of the building is to be redesigned to include at least two breaks in the 451-foot continuous wall at 3 stories, with minimum 50 foot sections of wall height not to exceed 25 feet in height (see Attachment C diagrams). Similar breaks should be provided along the Park Boulevard frontage. The Park Boulevard frontage is to be redesigned to provide a commercial pedestrian-oriented fagade with frequent door openings, awnings, and street- furniture (see Attachment C diagrams). If the Council chooses to approve the modified project as outlined in the Alternative Design, staff will prepare a Record of Land Use Action for consideration on a future Consent Calendar. RESOURCE IMPACT The proposed project will generate additional General Fund revenues in the form of development impact fees and additional property taxes, sales taxes, and utility user taxes. CMR: 418:06 Page 4 of 6 One-time development impact fees are estimated at $659,400. Additional annual revenues would include property taxes, sales taxes, and utility user taxes. The owner estimates that after the improvements are complete, the property will be valued at $50 million or $40 million more than its 2006 assessed value. This represents a $36,000 increase in annual City property tax revenues. Furthermore, the residents of the property, along with the employees in the Research and Development portions of the building, are expected to make purchases that will add in the range of $14,000 to $16,000 in armual sales tax revenues, as well as $12,000 to $14,000 in additional utility user tax revenues to City coffers. That brings the total annual revenue impact to between $62,000 and $66,000. On the expenditure side, the project would add 84 new residential units - with a combined total of 125 bedrooms - to the City housing stock. This will create new demands for City services such as community services, planning, police and fire. While quantification of the expenses for an individual project is difficult to project due to the incremental nature of service delivery costs, staff notes that development impact fees for Community Services and the Library Departments are designed to cover the incremental facility needs of the new residents. Similarly, service fees in Utilities, Community Services and Planning are designed to recoup operating expenses associated with, for example, the delivery of utility services, classes, sports programs, plan reviews, and project permits. Police and Fire services to the Palo Alto community, however, are paid by the General Fund, as are Public Works (roadway and drainage improvements) and general government services. Although the incremental impacts of this project alone are not expected to require additional General Fund staffing, when all recent projects under consideration, including, 901 San Antonio and Hyatt Rickey’s, come on line, the cumulative impact may require additional staffing for services. The costsof such cumulative impacts will be reviewed in a broader study or in the context of the upcoming Comprehensive Plan Amendment. ENVIRONMENTAL REVIEW The proposed project is subject to environmental review under provisions of the California Environmental Quality Act (CEQA). An Environmental Impact Assessment was prepared for the project. It was determined that the project could have potentially significant aesthetic, noise, traffic, and hazardous materials impacts. A Mitigated Negative Declaration has been prepared and is included as Attachment F. The document was available for public review and comment during a 20-day inspection period beginning November 1, 2006 to November 20, 2006. Comments from the applicant are expected prior to the Council meeting, but no other comments have been received by staff prior to preparation of the CMR. No action is required for the environmental document if the project is denied. If the project is approved, mitigation measures related to Aesthetics may need to be deleted or revised prior to adoption of the Mitigated Negative Declaration..

Court House Plaza Company, property owner, has requested the City’s approval of a Major Architectural Review application to allow the construction of a three story building to include 50,467 .square feet for research and development space on the ground floor and 104,971 square feet for two floors of residential apartments totaling 84 units, plus a subterranean parking garage and related site improvements. The application includes requests for Design Enhancement Exceptions to exceed the maximum allowable building height, encroach into the side and rear daylight plane, reduce the front and street side setbacks, and increase the maximum allowable lot coverage (The Project). B. The Project would include the demolition of all existing structures on site. The apartment units would have three unit types, ranging in size from 964 - 1,420 square feet and would be distributed throughout the upper two floors. Parking would be provided in a full underground basement with space for 274 vehicles. An additional 28 spaces (nine in landscape reserve) would be at grade and located in the courtyard. Access for the surface spaces and a separate ramp for access to the below grade garage would both be from Park Boulevard. The project site is approximately 1,600 feet from the California Avenue commercial center and Caltrain station. C. Following Staff review, the Architectural Review Board (ARB) reviewed the design components of the project during a public hearing on September 7, 2006 and recommended approval of the project with conditions to the Director of Planning and Community Environment (Director), with regard only to the project design, not zoning compliance (General Manufacturing zoning). D. On September 15, 2006 the Director denied the project based on noncompliance with zoning criteria. E. On October 16, 2006, the applicant’s appeal of the Director’s denial was considered by the City Council. The Council removed the item from the Consent Calendar and scheduled it for a public hearing. F. On November 20, 2006 the Council of the City of Palo Alto upheld the Director’s decision to deny the Major Architectural Park Plaza Page 1 Review board application with findings that the zoning ordinance requirements and design review criteria were not met. SECTION 2 Compliance with Zoning Regulations The Director of Planning and Community Environment and the City Council have determined that the project as proposed is not in compliance with Title 18 of the Palo Alto Municipal Code (Zoning): Palo Alto Municipal Code Section 18.01. 030: No land shall be used, and no facility, structure, or building shall be erected, constructed, enlarged, altered, moved, or used in any district, as shown upon the zoning map, except in accord with the regulations established by this title. A. The project does not conform with the GM(B)(General Manufacturing) Combining District regulations, which were in effect when submitted for ARB review on August 4, 2005. At that time, the GM(B) zone included multi-family residential and mixed-use (residential and non-residential) as permitted uses. The zoning did not allow Research and Development use, however, and the floor area ratio (FAR) was limited to 0.5 (52,485 square feet) whereas the proposed project has a FAR of 1.5 (104,988 square feet). The project would not conform to required building setbacks and daylight planes, or parking requirements, and exceeds the maximum allowable site coverage and building height. B. The project does not conform to the development regulations of the GM zone (the current zoning). The proposed mixed-use development is not permitted on the site as~residential use is not allowed in the GM zone. The maximum allowable floor area ratio (FAR) is 0.5 (52,485 square feet) and a FAR of 1.5 (104,988 square feet) is proposed. The project would not conform to required building setbacks and daylight planes, or parking requirements, and exceeds the maximum allowable site coverage and building height. SECTION 3 Architectural Review Findings The Director of Planning and Community Environment and the City Council have determined that the project as proposed is not in compliance with the following Architectural Review Findings, as specified in PAMC Section 18.76.020(d) : The design promotes harmonious transitions in scale and character in areas between different land uses. The design is consistent and compatible with applicable elements of the Palo Alto Comprehensive Plan, specifically Policy L-49, which reads "Design buildings to revitalize streets and public spaces and to enhance a sense of community safety. Provide an ordered variety of entries, porches, windows, bays and balconies Park Plaza Page 2 along public ways where it is consistent with neighborhood character; avoid blank walls or solid walls at street level; and include human-scale details and massing." The project is not designed to reduce building mass, provide a transition to Alma Street, or improve the pedestrian streetscape along Park Boulevard. The proposed project would include a 451-foot long, 3-story wall along both the Alma Street Elevation and Park Boulevard frontage. The massing of the walls is not mitigated with vertical relief and horizontal plane variations. The Park Boulevard frontage is not designed as a pedestrian-oriented faqade with frequent door openings, awnings, and street furniture.

September 15, 2006 Attachment D City of Palo Alto Department of Planning and Community Environment Harold Hohbach Court House Plaza Company 29 Lowery Drive Atherton, CA 94027 Subject:195 Page Mill Road, 2825, 2865, 2873, 2891 & 2901 Park Boulevard [05PLN-001751 Dear Mr. Hohbach: On Thursday, September 7, 2006, the Architectural Review Board reviewed the above referenced application and recommended approval with conditions to the Director of Planning and Community Environment. However, the Director of Planning and Community Environment cannot approve the application because (1) the proposed mix of uses are not permitted in the General Manufacturing (GM) zone district, (2) the project exceeds the allowable Floor Area Ratio (FAR) permissible within the GM zone district, and (3) the Design Enhancement Exception findings cannot be made for the requested exceptions from code regulations related to height, daylight plane, setbacks, and lot coverage. In addition, the request for concessions under Senate Bill (SB) 1818 is not, in staff’s estimation, complete or sufficient to support the project under SB 1818. The request does not provide detailed economic justification that the requested mixed use, FAR and DEE’s are necessary to provide the affordable housing units. Determination of the adequacy of the supporting financial analysis is a maj or policy interpretation that should be considered by the City Council prior to application of SB 1818 to a specific site in the City of Palo Alto. This Director’s decision shall become final fourteen calendar (14) days following the date of this letter, unless an appeal is filed pursuant to PAMC Chapter 18.78. If an appeal is received, the decision of the Director will be reviewed by the City Council within 30 days of receipt of the appeal. Should you have any questions regarding this maj or ARB action, please contact Christopher Riordan at (650) 329-2149 or chris.riordan@cityofpaloalto.org.

THE PROJECT INCLUDES A REQUEST FOR DESIGN ENHANCEMENT EXCEPTIONS TO EXCEED THE MAXIMUM ALLOWABLE BUILDING HEIGHT, ENCROACH INTO THE SIDE AND REAR DAYLIGHT PLANE, REDUCE THE FRONT AND STREET SIDE SETBACKS AND INCREASE THE LOT COVERAGE. RECOMMENDATION Staff recommends that the City Council decline to hear the appeal by Courthouse Plaza Company and uphold the Director of Planning and Community Environment’s decision to deny the Major Architectural Review Board application as outlined in Attachment A. BACKGROUND The City’s streamlined review process, including the Architectural Review procedures, provides for a City Council "call up" of appeals. If the Director’s decision is appealed, the project is sent to Council on the consent calendar. In the case of Architectural Review applications, three Council Member votes are required to remove the project from the consent calendar. The Council’s options under Palo Alto Municipal Code Section (PAMC) 18.77.070(0 are as follows: 1.Adopt the decision of the Director on the Consent Calendar; or 2.Upon the motion, second and affirmative vote of three Council Members, remove the item from the Consent Calendar. CMR: 396:06 Page 1 of 6 Should the matter be removed from the Consent Calendar, the Council then has two options: 1.The Council may discuss the appeal and adopt findings and take action on the appeal based upon the evidence presented at the hearing of the Architectural Review Board; or 2.The Council may set the matter for a new public hearing at a future date, following which the Council shall adopt findings and take action on the application. Once removed from the Consent Calendar, either of the above two options may be decided by a majority vote of the Council. Staff notes that California Environmental Quality Act (CEQA) review and conditions of approval have not been prepared for this project, so any affirmative action should include direction to staff to prepare these documents prior to final approval. Pro_iect Description The project would include the demolition of all existing structures on site, which include vacant corrugated metal and concretebuildings, and the construction of a 157,387 square foot, three-story, residential apartment and research and development (R&D) building with at grade parking and one level of below grade parking, on an approximately 2.5 acre parcel. The 50,467 square foot first floor would be dedicated for R&D space. Eighty- four (84) rental apartments totaling 104,971 square feet would be located on the upper two floors. The ARB formally reviewed the project on June 1, 2006 and continued the project to a date uncertain to allow the applicant sufficient time to respond to issues raised by the Board. On September 7, 2006, the ARB reviewed the applicant’s proposed changes and recommended approval of the project, including the requested Design Enhancement Exceptions (DEE’s), to the Director. On September 15, 2006, a written Director’s decision was issued denying the project as (1) the proposed mix of uses are not permitted in the General Manufacturing (GM) zone district, (2) the project exceeds the allowable Floor Area Ratio (FAR) permissible within the GM zone district, and (3) the Design Enhancement Exception findings cannot be made for the requested exceptions. A copy of this decision is included as Attachment A. On September 28, 2006, an appeal was formally filed by Courthouse Plaza Company. The letter of appeal is included as Attachment B. The applicant requested DEE’s for specific elements of the project. These included requests to exceed the maximum allowable building height, to encroach into the side and rear yard daylight plane, to reduce the front and street side yard setbacks, and to increase the maximum allowable lot coverage. A table showing the requested exceptions is included as Attachment F. CMR: 396:06 Page 2 of 6 DISCUSSION The applicant’s appeal is based on the zoning history of the site, the City’s designation of the site for housing, on State housing law, and on the applicant’s objections to Pedestrian and Transit Oriented Development (PTOD) Combining District zoning requirements. Each of these issues is addressed below: Zoning Compliance This project was formally submitted for ARB review on August 4, 2005. At that time, the GM(B) (General Manufacturing) Combining District zone development standards were in effect. Even under the original GM(B) zoning, the proposed project was not in compliance with the standards of that zoning designation. The GM(B) zone included multi-family residential and mixed-use as permitted uses but restricted the allowable floor area. ratio to .50:1. On October 11, 2005, the City Council passed a resolution removing the "B" overlay from the GM zone district and removed all housing and mixed- use (residential and nonresidential) development as permitted uses. Because this project had been submitted for ARB review prior to the changes adopted by the Council, the Council specifically exempted this project from the changes, allowing it to proceed through the review process under the GM(B) development standards. The current site zoning is GM and the applicant chose to submit the project for ARB review pursuant to the GM zoning. The proposed proiect does not, however, comply with zoning requirements for the GM zone, since residential (including mixed use) is not allowed in the GM zone. Also, the maximum allowable FAR in the GM zone is 0.5, as compared to the 1.5 FAR proposed. The applicant has argued that residential must be allowed on the site, since it is designated as a Housing Opportunity Site in the City’s Housing Element. While the City Attorney concurs, there are currently no standards for allowing mixed use in the GM zone. Attachment F compares the proposed project to the standards in effect (using the RM-30 zone for the residential component) for mixed use in the GM zone prior to Council action to delete residential uses in October of 2005. Several areas of. noncompliance with zoning under that scenario are identified in Attachment F. Housing Sites Inventory The Housing Element of the Palo Alto Comprehensive Plan includes a Housing Sites Inventory identifying potential housing sites most suitable and likely to be developed for residential purposes. Included on this list is a 3.92 acre site, which includes the portion of Page Mill Road north of Park Boulevard (potential public safety building site), and a portion of the subject property. The anticipated zoning of these parcels was RM-40 with a combined dwelling unit yield of 120 units. The applicant’s project includes three parcels, 195 Page Mill Road (APN# 132232-003), 2825/2865/2873/2891 Park Boulevard (APN# 132-32-004) and 2901 Park Boulevard (APN# 132-32-005) for a total of 2.41 acreS. Of these three parcels, the approximately .81 acre parcel at 2901 Park Boulevard is not on the Housing Sites Inventory. It is unclear whether housing would be allowed on this portion of the site, but staff believes that it may be appropriate based on an earlier (2004) City-initiated rezoning to RM-40, CMR: 396:06 Page 3 of 6 which was never adopted. The remaining two parcels that are on the Housing Sites Inventory List are a total of approximately 1.56 acres, which would yield 62 dwelling units under RM-40 zoning regulations. Housing Law (Senate Bill 1818) The applicant has requested a concession under SB 1818. Senate Bill 1818 amended the State density bonus program and became effective on January 1, 2005, The relatively new law requires cities to offer incentives or concessions to encourage the construction of affordable housing (allowances for mixed use, increased FAR or height, reductions in parking, setbacks, open space, etc.) based on the percentage of affordable units in a development. The law specifies that: One incentive or concession is to be granted for projects with at least 10 percent of the total units for lower income households; Two incentives or concessions are to be granted for projects that include at least 20 percent of the total units for lower income households; Three incentives or concessions are to be granted for projects that include at least 30 percent of the total units for lower income households. The project would include 17% of the total residential units as below market rate (BMR) units. Given the provisions of SB 1818, the applicant may be eligible for one concession based on. the number of affordable housing units proposed. However, the City of Palo Alto (as well as most cities), has not adopted a policy or program to identify what concessions or incentives are appropriate and the level of discretion available to the City upon review. The applicant’s request for concessions under SB 1818 is not, in staff’s estimation, sufficient to support the project under SB 1818, particularly since at least two concessions (mixed use, FAR, and setbacks/daylight plane exceptions) would be needed. SB 1818 also allows a city to require financial information and analysis to demonstrate that the concessions are needed to provide for the affordable units. The applicant has provided an analysis that lacks specific comparable costs and revenues, as well as a capitalized income/loss stream for the project. Staff recommends that no project be approved under SB 1818 without the Council’s review of the project. Pedestrian Transit Oriented Development The proposed project is located within the boundaries of the recently approved PTOD Combining District. Staff has recommended that the applicant revise the project to comply with the PTOD criteria, which would accommodate the residential density, but would reduce the non-residential portion of the project by half. The intent of the PTOD is to foster densities and facilities that support concepts such as the use of public transportation, streetscape design elements that are attractive to pedestrians and bicyclists, and project design that achieves an overall context-based development for the PTOD overlay area. When the Planning and Transportation Commission recommended approval of the PTOD, the Commissioners expressed their expectation that this project would conform to the PTOD standards. Attachment G compares the project to the standards adopted by the Council for the PTOD zoning. CMR: 396:06 Page 4 of 6 On July 24, 2006, the City Council adopted, on first reading, the recommended PTOD Combining District and criteria for context-based design. Second reading of the ordinance occurred on September 11, 2006, and the ordinance became effective on October 11, 2006. On September 11, 2006, the City Council directed staff to initiate PTOD zoning for the subject property. The Planning and Transportation Commission was scheduled to consider the rezoning on October 11, 2006, and Council consideration of the zoning is tentatively set for November 13, 2006. RESOURCE IMPACT The proposed project will generate additional General Fund revenues in the form of development impact fees and additional property taxes, sales taxes, and utility user taxes. One-time development impact fees.are estimated at $659,400. Additional annual revenues would include property taxes, sales taxes, and utility user taxes. First, the owner estimates that after the improvements are complete, the property will be valued at $50 million or $40 million more than its 2006 assessed value. This represents a $36,000 increase in annual City property tax revenues. Furthermore, the residents of the property, along with the employees, in the Research and Development portions of the building, are expected to make purchases that will add in the range of $14,000 to $16,000 in annual sales tax revenues, as well as $12,000 to $14,000 in additional utility user tax revenues to City coffers. That brings the total annual revenue impact to between $62,000 and $66,000. On the expenditure side, the project would create 84 new residential units - with a combined total of 125 bedrooms - to the City housing stock. This will create new demands for City services such as Community Services, Planning, Police and Fire. Development impact fees for Community Services and the Library departments are designed to cover the incremental facility needs of the new residents. Generally, service fees in Community Services and Planning are designed to recoup operating expenses associated with, for example, the delivery of classes, sports programs, plan reviews, and project permits. Police and Fire services to the Palo Alto community, however, are paid by the General Fund (GF). Although. the incremental impacts of this project alone are not expected to require additional GF staffing, when all projects under consideration, such as this project, 901 San Antonio, and Hyatt Rickey’s, come on line, the cumulative impact may require additional staffing for services. ENVIRONMENTAL REVIEW An initial study was prepared for this project but was not circulated, as the staff recommendation to the Architectural Review Board was for denial of the project based upon the project’s deficiencies with respect to the existing zoning of the property. If the Council determines that the project should be scheduled for a public hearing, staff should also be directed to prepare a Mitigated Negative Declaration prior to final Council action.

Landscaping The proposed landscaping plan will include a fountain near the "at grade" vehicle entrance to the courtyard, a landscaped interior courtyard with decorative paving, and new landscaping on both Park Boulevard Page Mill Road. Coast Redwoods and Canary Island Pine trees would be planted adjacent to the rear of the building in the Joint Powers Board right-of-way to help screen the project from Alma Street. II.DETERMINATION In accordance with the City of Palo Alto’s procedures for compliance with the California Environmental Quality Act (CEQA), the City has conducted an Initial Study to determine whether the proposed project located at 195 Page Mill Road, 2825,2865,2873,2891,2901 Park Boulevard could have a significant effect on the environment. On the basis of that study, the City makes the following determination: The proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION is hereby adopted. X Although the project, as proposed, could have a significant effect on the environment, there will not be a significant effect on the environment in this case because mitigation measures for traffic impacts have been added to the project and, therefore, a MITIGATED NEGATIVE DECLARATION is hereby adopted. The attached initial study incorporates all relevant information regarding the potential environmental effects of the project and confirms the determination that an EIR is not required for the project. In addition, the following mitigation measures have been incorporated into the project: MM #1 Revised plans and supplemental information shall be submitted to staff and the ARB for review and approval prior to submittal for building or grading permits. The development plans and supplemental information shall address the ARB’s conditions and include the following: a. The vast plain of paving in the interior courtyard should be broken up by the increased use of landscaping or site furnishings. S:kPLAN~LADIV~Current Planning’~EIA~VIIGDEC.ML~Park Plaza, doe b. The first floor windows on Park Boulevard shall be taken down to the ground to allow for the possibility of providing front entrances to the first floor Research and Development space on the ground floor. c. The lighting on the Park Boulevard fa~;ade shall be increased without the use of uplights which could shine into the residential units on the second and third floor. d. The number of reveals on the siding shall be limited to two. e. The bike lockers and the transformers that are presently in the courtyard shall be relocated. f. The design of the entrance tower at the corner of Park Boulevard and Page Mill Road shall be further refined with the possibility of making it wider to make it more accentuated.~ g. The color scheme shall be reviewed to determine if they "scale up". h. The planting of trees along the rear elevation shall be more uniform. i. The number of windows on the rear elevation shall be increased with the purpose of providing more natural light for the hallways. j. The future Research and Development uses on the ground shall not include the use of hazardous materials. MM #2 k. In addition to the ARB requirements, revised plans shall also be submitted to staff and the ARB for review and approval prior to submittal for building or grading permits to address massing and streetscape concerns. Redesign the rear of the building to comply with a daylight plane of 16 feet in height as measured at the rear property line with an angle of 45 degrees, and with at least two breaks in the 450 foot continuous wall at three stories, with minimum 50 foot sections of wall height not to exceed 25 feet in height. !. Redesign the Park Boulevard frontage to provide a commercial pedestrian-oriented fasade with frequent door openings, awnings, and street-furniture. MM #3 Prior to issuance of any building permit or grading permit, reports documenting the location of hazardous waste contaminants in the soil and/or groundwater shall be provided to the SCVWD and RWQCB for review and project approval, if required. Written confirmation from the San Francisco Bay Regional Water Quality Control Board (Regional. Board) shall be submitted to the City, either 1) indicating that no contamination exists; or 2) that the proposed construction and site activities, including underground parking, dewatering sumps or wells will not result in exposure of workers or the public to those contaminants and that such construction will not have an adverse impact on the ongoing or future groundwater cleanup efforts; or 3) mitigation measures to be reviewed and approved by the Regional Board will provide adequate protection from exposure. A Risk Management Plan shall be submitted to and must be approved by the Regional Board, if required. If contamination does not exist beneath the subject property, the applicant shall provide information regarding the lateral distance to existing groundwater contamination plumes and an analysis of the potential impacts to those plumes from construction activity on the subject property, including the use of dewatering sumps or wells under the proposed underground parking structure. This information shall be submitted to the Regional Board for approval that the proposed work on the subject property, including any use of dewatering sumps or wells will not have an adverse impact on the current and future cleanup efforts. The approval shall verify that dewatering sumps or wells, if proposed, would not alter the path of the groundwater contamination plume(s) and could not result in bringing groundwater contamination to the subject property or a possible future exposure of the public on the subject property to groundwater contaminants. S:gaLAN~PLADIV~Current Planning~EIA’~MIGDEC.ML’xPark Plaza.doc MM #4 The project shall include design features to reduce the maximum indoor noise level to as close as the 45dB standard as feasible through project design.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.X I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect: 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a s.ignificant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e. g. the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project-specific factors as well as general standards (e. g. the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2)All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3)Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effeet may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4)"Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 17, "Earlier Analysis," may be cross-referenced). 5)Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration [Section 15063 (3) (D)]. In this case, a brief discussion should identify the following: a)Earlier Analysis Used. Identify and state where they are available for review. b)Impacts Adequately Addressed. Identify which effects from the above checklist.were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6)Lead agencies are encouraged to incorporate into the checklist references to information sources for.potential impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7)Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8)This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a projects environmental effects in whatever format is selected. 9)The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)- 4 - Issues and Supporting Information Sources Sources Potentially Significant Issues Potentially Significant Unless Mitigation Incorporated Less Than Significant Impact No Impact I.

Aesthetics (a-c) Visual Character- The areas most sensitive to visual impacts are those along Park Boulevard, Alma Street, and nearby residential areas. Palo Alto Comprehensive Plan Policy L-48 instructs, "Design buildings to revitalize ’ streets and public spaces and to enhance a sense of community and personal safety. Provide an ordered variety of entries, porches, windows, bays and balconies along public ways where it is consistent with neighborhood character; avoid blank or solid walls at street level; and include human-scale details and massing." The site is located approximately 200 feet from single-family residential neighborhoods located on the north side of Alma Street. Separating these homes from the project site is the Joint Powers Board (Caltrain) right- of-way and Alma Street. Single-family residential is also located on Olive Avenue, approximately 300 feet from the project site. Multi-family residential is located on Park Boulevard, approximately 200 feet east of the project site. Residents of Olive Street and the multi-family project could be expected to use Park Boulevard to access the California Avenue Caltrain station, Page Mill Road, and the downtown district on and around California Avenue. The City’s Comprehensive Plan does not identify the project site as a scenic resource and the site is not located within any major identified view shed or view corridor. The Architectural Review Board (ARB) reviewed the proposed project on September 7, 2006 and recommended approval with conditions to the Director of Planning and Community Environment (Director). The ARB discussed design aspects that relate to the project in terms of scale, massing, colors and materials, neighborhood context, as well as design details that are integral to the success of the project. The conditions of approval were that the following items, which have been added as a mitigation measure, were to return to the ARB for review prior to submittal of a building or grading permit. a.The vast plain of paving in the interior courtyard should be broken up by the increased use of landscaping or site furnishings. b.The first floor windows on Park Boulevard shall be taken down to the ground to allow for the possibility of providing front entrances to the first floor Research and Development space on the ground floor. c.The lighting on the Park Boulevard fagade shall be increased without the use ofuplights which couJd shine into the residential units on the second and third floor. d.The number of reveals on the siding shall be limited to two. e.The bike lockers and the transformers that are presently in the courtyard shall be relocated. f.~The design of the entrance tower at the comer of Park Boulevard and Page Mill Road shall be further refined with the possibility of making it wider to make it more accentuated. g.The color scheme shall be reviewed to determine if they "scale up". h.The planting of trees along the rear elevation shall be more uniform. i.The number of windows on the rear elevation shall be increased with the purpose of providing more natural light for the hallways. j. The future Research and Development uses on the ground shall not include the use of hazardous materials. To break up the mass of the building along the Caltrain right-of-way, the following conditions were added by staff and have been added as mitigation measures. k. Redesign the rear of the building to comply with a daylight plane of 16 feet in height as measured at the rear property line with an angle of 45 degrees, and with at least two breaks in the 450 foot continuous wall at three stories, with minimum 50 foot sections of wall height not to exceed 25 feet in height. 1.Redesign the Park Boulevard frontage to provide a commercial pedestrian-oriented fagade with frequent door openings, awnings, and street-furniture. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)14 On September 15, 2006, the Director of Planning and Community Environment denied the project because it did not conform to the GM zone district development regulations and the findings for the requested DEE’s could not be made. Further discussion of the preceding is contained in the Planning and Land Use section of this report. The proposed project is required to meet the City of Palo Alto development standards and to ensure that the new construction would be compatible, harmonious and appropriate to the site and surrounding development. At a height of 43 feet, the proposed building will bring a considerably taller structure to the site than what currently exists. The building massing, fenestration, rooftop mechanical systems, and architectural details should be designed within the context of the immediate office/industrial neighborhood while respecting the nearby residential neighborhoods. Final review by the ARB will assure the consistency of these elements. Glare- Primary sources of light and glare in the daytime are reflections from windows and light colored surfaces. While some amount of glare could be expected during the daytime, it would be similar or even less than that which is created by other nearby buildings. No unusual sources of daytime glare from the project would be expected. Nighttime sources of light and glare can include vehicle headlights, streetlights, decorative outdoor landscaping or safety equipment, and interior lighting. Nighttime lighting would be expected to be similar to other lighting around the area. Adjacent properties are commercial, and few people would be affected by nighttime lighting on these properties. There is no proposed exterior lighting and only four proposed small "hallway" windows on the rear elevation facing Alma Street, therefore, lighting impacts on Alma Street residences would be minimal. Lighting impacts from the residential uses throughout the building are not expected to be a significant impact. The project applicant did not provide details of lighting fixtures or a photometric plan during the review bythe ARB to access lighting impacts on the area near the building. The ARB added a condition of approval to their recommendation that included a photometric plan to be reviewed by the ARB prior to submittal of a building permit to ensure that lighting levels are appropriate for the site and not detrimental to the surrounding land uses. This review would reduce any light or glare impacts to a less than significant level. Residual Impact:The following mitigation measures when incorporated into the project and reviewed by the ARB would reduce the aesthetic impacts of the project to a less than significant level. Mitigation Measures: MM #1 Revised plans and supplemental information shall be submitted to staff and the ARB for review and approval prior to submittal for building or grading permits. The development plans and supplemental information shall address the ARB’s conditions and include the following: a. The vast plain of paving in the interior courtyard should be broken up by the increased use of landscaping or site furnishings. b.The first floor windows on Park Boulevard shall be taken down to the ground to allow for the possibility of providing front entrances to the first floor Research and Development space on the ground floor. c.The lighting on the Park Boulevard facade shall be increased without the use of uplights which could shine into the residential units on the second and third floor. d.The number of reveals on the siding shall be limited to two. e.The bike lockers and the transformers that are presently in the courtyard shall be relocated. f.The design of the entrance tower at the corner of Park Boulevard and Page Mill Road shall be further refined with the possibility of making it wider to make it more accentuated. g. The color scheme shall be reviewed to determine if they "scale up". h. The planting of trees along the rear elevation shall be more uniform. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)15 i. The number of windows on the rear elevation shall be increased with the purpose of providing more natural light for the hallways. j. The future Research and Development uses on the ground shall not include the use of hazardous materials. MM #2 k. In addition to the ARB requirements, revised plans shall also be submitted to staff and the ARB for review and approval prior to submittal for building or grading permits to address massing and streetscape concerns. Redesign the rear of the building to comply with a daylight plane of 16 feet in height as measured at the rear property line with an angle of 45 degrees, and with at least two breaks in the 450 foot continuous wall at three stories, with minimum 50 foot sections of wall height not to exceed 25 feet in height. 1.Redesign the Park Boulevard frontage to provide a commercial pedestrian-oriented favade with frequent door openings, awnings, and street-furniture. (a-e) Agricultural Resources The proposed project site is located in a developed urban area and not located in an area of"Prime Farmland", "Unique Farmland", or "Farmland of Statewide Importance" as shown on the maps prepared for the Farmland Mapping and Monitoring Program of the California Resources Agency. The site is not zoned for agricultural use and is not regulated by the Williamson Act. Residual Impact: No impact Mitigation Measures: None IH.Air Quality a,b,c)The City of Palo Alto utilizes the Bay Area Air Quality Management District’s (BAAQMD) thresholds of significance for air quality impacts, as follows: Construction Impacts: The proposed project will involve grading, paving, and landscaping which has the potential to cause localized dust related impacts resulting in increases in airborneparticulate matter. Dust related impacts are considered potentially significant but can be mitigated with the application of standard dust control measures. Demolition and new construction activities could have a significant impact to air quality through the release of respirable particulate matter concentrations. Although there are no sensitive receptors in the vicinity of the subject site, the project is subject to City Building Department regulations that require approval of adequate dust abatement plans for construction activities for both demolition and new construction prior to the issuance of a building permit. The dust abatement plan requirements would reduce the potential significant air quality impacts relating to demolition and new construction of the project to less than significant. Long Term/Operational Impacts: Long-term and operational project emissions would stem primarily from motor vehicles associated with the proposed project. As discussed in the Transportation/Traffic section of this Environmental Impact Assessment, the project is not expected to result in a significant number of new vehicle trips. Motor vehicles are the major source of ozone precursors and contributors to carbon monoxide generation in the Bay Area. The trips generated by the proposed use do not require a permit from the Bay Area Air Quality Management District. Therefore, long-term air-quality impacts related to motor vehicle operation are expected to be less than significant. d)Sensitive receptors are defined as children, elderly, or ill people who can be adversely affected by air quality problems. The project is adjacent to a rail line, commercial, and automotive service uses and not immediately adjacent to housing or other sensitive, receptors. Research and development and residential land uses would not create substantial pollution concentrations in the area. City development standards and specific conditions of project approval would reduce potential negative air quality impacts of the project to less than significant. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)16 e)The proposed project would consist of commercial and residential uses and an underground parking garage. These uses do not typically create objectionable odors affecting a substantial number of people. The proposed project is not expected to create objectionable odors when the project is complete. Residual Impact: Less than significant Mitigation Measures: None Biological Resources Trees- No protected trees, including Coast Live Oak (Quercus agrifolia), Valley Oak (Quercus lobata) or Coast Redwood (Sequoia sempervirens) exist on the site. Residual Impact: Mitigation Measures: No Impact None V.Cultural Resources a-d)The project site is a developed area, and no archaeological or paleontological resources are expected to be uncovered. The site itself is considered to be located in an area of "moderate sensitivity" as identified in the Comprehensive Plan due to the proximity to the San Francisco Baylands and nearby creeks. Although existing and historic development has altered the native landscape, the potential exists than now-buried Native American artifacts could be uncovered during construction of the project. The 1998-2010Palo Alto Comprehensive Plan Update EIR included in it mitigations that areas of moderate sensitivity shall be "subject to surface survey and/or subsurface probing if(a) the area is unimproved land, (b) the project will entail excavation more than five below the existing grade on unimproved land, or (c) mass grading is anticipated for large commercial, transportation, or utility projects". Although the project would entail excavation of one level of underground parking, no archeological or paleontological resources are expected to be uncovered and therefore no subsurface probing or testing is necessary prior to construction of the project. If during grading and construction activities, any archaeological or human remains are encountered, construction shall cease and the Santa Clara County Medical Examiner’s office shall be notified to provide proper direction on how to proceed. If any Native American resources are encountered during construction, construction shall cease immediately until a Native American descendant, appointed by the Native American Heritage Commission of the State of California, is able to evaluate the site and make further recommendations and be involved in mitigation planning. The Director of Planning and Community Environment will decide the significance of an archaeological discovery and necessary mitigation measures. Mitigation Measures: Residual Impact: Less than significant ...... None VL Geology and Soils A geotechnical report, dated May 10, 2004, was prepared by Jo Crosby and Associates. A copy of the geotechnical report canbe found in Attachment C of this report. a) 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281) i. The entire state of California is a seismically active area. The City of Palo Alto is located within an area that is very geologically active. The San Andreas Fault, long considered to the major seismic risk in California, passes though the City (approximately 5 ½ miles to the southwest of the project site). The Comprehensive Plan states that the San Andreas Fault is capable of producing an earthquake with an 8.4 magnitude that would cause very violent groundshaking in much of Palo Alto. No known faults cross the project site; therefore fault rupture is very unlikely, but theoretically possible. All new construction would be subject to the provisions of the most current Uniform 17 Building Code, which are directed at minimizing seismic risk and preventing loss of life and property in the event of an earthquake. Therefore the project would result in a less than significant impact. ii. Seismic ground shaking could occur on the site and could impact structures and occupants of the project area due to seismic activity associated with regional faults such as the San Andreas, and thrust faults across Palo Alto to the San Andreas and the Hayward Fault. iii. The goal of Policy N-51 of the Comprehensive Plan is to "Minimize exposure to geologic hazard, including slope stability, subsidence, and expansive soils, and seismic hazards including ground shaking, fault rupture, liquefaction, and land sliding". The risk from seismic events would be reduced to a level that must be accepted by people living in a seismic active area, and therefore this would be considered a less than significant impact. b)No changes to the site topography will occur as a result of the proposed project. Grading activity will be limited to the soil removal for the construction of the underground-parking garage. A final grading and drainage plan for the project is subject to the approval of the Public Works Department prior to the issuance of a building permit. The application of standard grading, drainage, and erosion control measures as part of the approved grading and drainage plan and the recommendations from the Geotechnical Report is expected to mitigate and grading-related impacts to a less than significant level. e)The project will not involve the use of septic tanks or alternative waster-water disposal systems. Residual Impact:Implementation of the construction techniques and recommendations contained in the report by Jo Crosby & Associates, dated May 10, 2004, would be added as a project condition of approval. Additionally, the Building Division and the Department of Public Works would review the project. Implementation of the recommendation contained in the Geotechnical report and the review by the City of Palo Alto would reduce geological impacts to a less than significant level Mitigation Measures: None VII. Hazards and Hazardous Materials a,b,c)The project will not involve the use or storage of hazardous materials. A condition of approval by the ARB would prohibit the use of hazardous materials in connection with the research and development use. d)The Geotechnical Report prepared by Jo Crosby and Associates did not identify toxic materials on the property; however, the report states that a toxic plume of contaminated groundwater underlies the site. This contamination was caused by historic discharges from nearby electronic manufacturing plants. The toxic plume has been known to exist since at least 1981 and is commonly referred to as the Hewlett-Packard-Varian plume, The extent of the plume and its contaminants are well known and documented, and a number of developments have been built in the area, including residential uses, over this plume. Excavation for the underground garage and foundation for the building would not exceed 20 feet. The geotechnical report states that groundwater was located at soil depths below twenty feet. The planned excavation is less than 20 feet so making contact with the groundwater would not be expected. e,f) g) The project site is not located within two miles of either a public or private use airport. The project will not affect circulation patterns in the vicinity of the project and, therefore, will not interfere with either emergency response or evacuation. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)18 h)The project is in a developed area and will not expose people or structures to a significant risk of loss, injury, or death involving wildland fires. Residual Impact: Mitigation Measures: Contact with contaminated groundwater is not expected during project construction but there still is the chance that groundwater could be encountered during project construction. Given this possible likelihood, the following mitigation measure would be incorporated into the project conditions of approval to reduce these impacts to a less than significant level. Prior to issuance of any building permit or grading permit, reports documenting the location of hazardous waste contaminants in the soil and/or groundwater shall be provided to the SCVWD and RWQCB for review and project approval, if required. Written confirmation from the San Francisco Bay Regional Water Quality Control Board (Regional Board) shall be submitted to the City, either 1) indicating that no contamination exists; or 2) that the proposed construction and site activities, including underground parking, dewatering sumps or wells will not result in exposure of workers or the public to those contaminants and that such construction will not have an adverse impact on the ongoing or future groundwater cleanup efforts; or 3) mitigation measures to be reviewed and approved by the Regional Board will provide adequate protection from exposure. A Risk Management Plan shall be submitted to and must be approved by the Regional Board, if required. If contamination does not exist beneath the subject property, the applicant shall provide information regarding the lateral distance to existing groundwater contamination plumes and an analysis of the potential impacts to those plumes from construction activity on the subject property, including the use of dewatering sumps or wells under the proposed underground parking structure. This information shall be submitted to the Regional Board for approval that the proposed work on the subject property, including any use of dewatering sumps or wells will not have an adverse impact on the current and future cleanup efforts. The approval shall verify that dewatering sumps or walls, if proposed, would not alter the path of the groundwater contamination plume(s) and could not result in bringing groundwater contamination to the subject property or a possible future exposure of the public on the subject property to groundwater contaminants. a,c-f) b) g,h,i) Hydrology and Water Quality Construction of the building will change the amount of impervious surface area on the site. The existing drainage pattern of the site will also be substantially altered as a result of the project. City Standard Conditions of Approval require the incorporation of Best Management Practices for storm water pollution prevention in all construction operations, in conformance with the Santa Clara ValleyNon-Point Source Pollution Control Program. A drainage plan for the site, including the roof drainage, shall be submitted with the building permit application to address potential water quality impacts. A discussion of the projects impacts on potentially contaminated groundwater is discussed in the previous section (Hazards and Hazardous Materials). The project site is not located in an area of groundwater recharge, and will not deplete groundwater supplies. The site is not located within a 100-year flood hazard area. A Public Works Department condition of approval requires that the site be designed to divert overland water flow away from the entrance to the underground garage ramp. The project applicant is also required to submit a final site grading and drainage plan prior to issuance of a building permit that conveys site runoff to the nearest adequate municipal storm drainage system and/or 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)19 landscaped area per the adopted Storm Water Pollution Prevention Plan. Conformance to the requirements of the Public Works Department will reduce flood hazard impacts to a less than significant level. j)The project site is not an area that is.subject inundation by seiche, tsunami, or mudflow. Residual Impact:Less than significant Mitigation Measures:None required IX. Land Use and Planning b)The Comprehensive Plan designation for the site is Light Manufacturing and the zoning district is General Manufacturing. The project would not, however, be in conformance with the development standards set forth in Palo Alto Municipal Code (PAMC) Chapters 18.20 (Office, Research, and Manufacturing Districts). The proposed project does not comply with zoning requirements for the GM zone, since residential (including mixed use) is not allowed in the GM zone. Also, the maximum allowable FAR in the GM zone is 0.5, as compared to the 1.5 FAR proposed. Housing must be allowed on the site though, since it is designated as a Housing Site in the City’s Housing Element. However, there are currently no standards for allowing mixed use in the GM zone. Staff has therefore also applied RM-40 standards to the project in the absence of standards for residential use. The project includes requests for Design Enhancement Exceptions as listed in the following table: Front Setback Right Side Setback Rear Setback Site Coverage Building Height (mechanical screening at comer of Park Boulevard and Page Mill Road) Daylight Plane REQUIRED 20 feet for residential 10 feet for 1 st Story 19 feet for 2nd and 3rd Stories 10 feet for 1 st Story 19 feet for 2nd and 3rd Stories (.45) 41,989 sq. ft. 55 ft (15 feet allowed above the 40’ height limit of the RM-40 zone) Five feet at side and rear property lines and angle of 45 degrees PROPOSED 9ft. 10ft. Oft. (.49) 51,729 sq. ft. 59’-4" ft. Entire bldg, length of both sides and rear encroach Note: RM-40 development standards applied for residential use. CONFORMANCE Would not conform DEE Requested Would not conform DEE Requested Would not conform DEE Requested Would not conform DEE Requested Would not conform DEE Requested Would not conform DEE Requested Floor Area Ratio, Residential Density, and Use The maximum allowable FAR in the GM zone is .50:1 (52,485 square feet). The proposed floor area ratios for the R&D and residential portions of the project would be .48 (50,467 square feet) and 1.02 (106,920 square feet), respectively. The project would exceed the maximum allowable floor area allowable on the site by 104,988 square feet. Building Height and Daylight Plane The maximum allowable building height in the GM Zone district is 50 feet however, since RM-40 development standards are applied to the residential use, the maximum building height is reduced to 40 feet. Fifteen feet of additional height is allowed for rooftop mechanical and elevator equipment and screening. The proposed building measures approximately 37’- 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)20 8" to the top ofthe roof. A 20’-8" tall mechanical equipment enclosure would be located on the roof at the intersection of Park Boulevard and Page Mill Road for a total height of 59’-8". The mechanical equipment enclosure would exceed the allowable height exception for mechanical equipment by 4’-4". Housing Law (Senate Bill 1818) The applicant has requested concessions (relief from zoning requirements) under Senate Bill (SB) 1818. SB 1818 amended the State density bonus program and became effective on January 1, 2005. The relatively new law requires cities to offer incentives or concessions to encourage the construction of affordable housing (allowances for mixed use, increased FAR or height, reductions in parking, setbacks, open space, etc.) based on the percentage of affordable units in a development. The law specifies that: One incentive or concession is to be granted for projects with at least 10 percent of the total units for lower income households; Two incentives or concessions are to be granted for projects that include at least 20 percent of the total units for lower income households; Three incentives or concessions are to be granted for projects that include at least 30 percent of the total units for lower income households. The project would include 13 (15%) of the total residential units as below market rate (BMR) units. Given the provisions of SB 1818, the applicant may be eligible for one concession based on the number of proposed affordable housing units. To be eligible for two concessions the project would need to set aside 17 (20%) of the residential units as BMR units. Parking Based on the parking requirements contained in Chapter 18.83 of the Palo Alto Municipal Code, the project will require 379 parking spaces. 302 parking spaces would be provided on site which includes 19 at grade spaces, 274 spaces in a subterranean parking garage, and 9 in landscaped reserve. Entrance to the underground facility would be located on Park Boulevard at approximately the midpoint of the building. The uses on the site require that 379 parking spaces are to be provided. The project would include both Research and Development and Residential use. Ci_ty Council Review The project will be reviewed by the City Council, which Will consider the applicant’s requests for concessions under SB 1818, parking reductions, and Design Enhancement Exceptions to encroach into the required building setbacks, daylight plane, and exceed the maximum allowable site coverage and building height. The project would be in conformance with the zoning ordinance if the City Council approves the requests subject to Mitigation Measures 1-2 (Aesthetics) and 5-9 (Transportation and Traffic). Residual Impact:Mitigation Measures 1-2 (Aesthetic impacts) and Mitigation Measures 5-9 (Transportation and Traffic) would reduce the Land Use and Planning impacts to a less than significant level. Mitigation Measures: None. X.Mineral Resources a,b)The project site is not located in a designated mineral resource recovery site. No impacts to mineral resources are expected. Residual Impact: Mitigation Measures: No impact None 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)21 XI. ’ Noise a,b,c,d)Noise sensitive receptors are those areas that are more sensitive to ambient noise levels than other areas~ The proposed project, with 84 residential units, would be considered a sensitive receptor. The two significant sources of noise are vehicle traffic from roadways (primarily arterial roads) and railroad operations. Other sources of noise include the daily activities that take place in the area. The City Noise Element of the Comprehensive Plan and California State Title 24 standards specify a limit of 60 dBA DNL (Average day-night level, also call Ldn) for exterior residential uses and 45 dBA DNL for interior living spaces. The 60 dBA DNL for the City noise element is a guideline with the understanding that a 60 dBA DNL is a goal that cannot be reached in all residential areas. The California Building Code requires that mechanical ventilation of air conditioning be provided for every room exposed to this sound level (60 dBA). The proposed project site is exposed to noise levels of 70 dBA DNL based on the Comprehensive Plan Noise Exposure Contour Map. These ambient conditions include noise from nearby land uses, traffic noise from Alma Street and Page Mill Road and rail noise from Union Pacific Railroad/Cal Train line. According to a noise assessment study conducted by Charles M. Salter Associated, Inc. in June 2004 the existing noise environment on- site is due primarily to vehicular traffic and the CalTrain line. The noise study identified noise levels from 65 dBA (auto traffic noise) to 74 dBA (train noise). Noise levels indicate that building design measures are required to reduce noise level exposure for the project residents. The site is exposed to traffic noise emanating from Alma Street, Park Boulevard, and Page Mill Road; and to noise generated by trains on the adjacent CalTrain right of way. Based on the Noise Exposure Contours Map (N-3) contained in the Comprehensive Plan, the subject property is exposed to noise levels of 70 Ldn. Noise: Significance Criteria The Comprehensive Plan defines severe noise levels that would cause a significant impact. According to these criteria, the project would have a significant noise impact if it would result in exposure of people to short term construction noise and long-term severe noise levels. A "severe" noise impact is determined under Palo Alto Comprehensive Plan Policy N-39, which describes the application of noise and land use compatibility guidelines to residential developments: PolicyN-39: Encourage the location of land uses in areas with compatible noise environments, Use the guidelines in the table "Land Use Compatibility for Community Noise Environment" to determine compatibility. The guideline for maximum outdoor noise levels in residential areas is an La, of 60 dB. This level is a guideline for the design and location of future development and a goal for the reduction of noise in existing development. However, 60 L,t, is a guideline, which cannot necessarily be reached in all residential areas within the constraint of economic or aesthetic feasibility. This guideline will be primarily applied where outdoor use is a major consideration (e.g. backyards in single family housing developments and recreational areas in multiple family housing projects). Where the City determines that providing an Ld, of 60 dB or lower outdoors is not feasible, the noise level in outdoor areas intended for recreational use should be reduced to as close as the standard as feasible through project design. The indoor noise level as required by the State of California Noise Insulation Standards must not exceed and Ldn of 45 dB in multiple family dwellings. This indoor criterion shall also apply to new single family homes in Palo Alto. Interior noise levels in new single family and multiple family residential units exposed to an exterior Ldn of 60 dB or greater should be limited to a maximum instantaneous noise level of 50 dBin the bedrooms. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)22 Maximum instantaneous noise levels in other rooms should not exceed 55 dB. Noise exposure can be determined based on the noise contour map included in this plan, or more detailed noise measurements, if appropriate. Noise: Environmental Impact Sound levels of greater than 60 dBA could be generated at the building fagade at any time during the day from vehicle traffic or operations associated with the CalTrain railroad. This is a potentially significant impact. As noted in the significance criteria above, the outdoor noise standard is generally an Ld, (average 24-hour noise level) of 60 dB. However, the City recognizes in some areas providing an Ld, of 60 dB or lower is not feasible. An example of this area would be adjacent to CalTrain. The proposed project has a building wall facing the CalTrain facing which would be exposed to an Ld, of 70. The standard requires interior noise levels be maintained at an Ld. of 45 dB or less. Further, if the exterior noise level is greater than 60 dB, then maximum instantaneous noise levels generated by repetitive, commonly occurring events should be maintained at 50 dB in bedrooms and 55 dB in other rooms. The study conducted by Charles M. Salter Associates recommended that windows in residential units have a minimum STC (sound transmission class) rating of 38 for units facing the CalTrain tracks. The Page Mill facing fagade, the Park Boulevard fagade, and the side facing Stanford European would have a minimum STC rating of 35, 32, and 35 respectively. Project related traffic would not cause a noticeable increase in noise on any public streets. However, the demolition of existing structures and construction of the project would temporarily increase current noise levels in the vicinity of the site. Typical noise sources would include mechanical equipment associated with excavation, removal of pavement, and construction vehicles. Construction hours would be limited to Monday through Friday 8:00 a.m. to 6:00 p.m. and Saturday 9:00 a.m. to 6:00 p.m., as per City requirements. All construction truck traffic shall conform to the City of Palo Alto Tracks and Traffic Ordinance (10.48) that details city truck routes. Measures designed to minimize the noise impacts will be designed into the project. For example, the noise assessment recommends Sound Transmission Class (STC) ratings for exterior windows and along the CalTrain tracks to meet the State Building Code Requirements. The project would include a minimum of STC 50-rated exterior walls facing CalTrain and bedroom windows would have a STC 45 rating. The exterior building fagade would act as a sound barrier for the courtyard facing facades. The noise study estimates that the DNL would be below 60. The courtyard building facades will not be required to have sound rated glass, e,f)The project site is not located within an airport land use plan or within the vicinity of a private airstrip. Residual Impact:Implementation of the following mitigation measure would reduce the noise related impacts to a less than significant level. Mitigation Measure: MM #4 The project shall include design features to reduce the maximum indoor noise level to as close as the 45dB standard as feasible through project design. To achieve this, STC rated exterior walls facing the Caltrain shall have an STC rating of at least 50. Exterior glazing for bedrooms facing CalTrain shall have a minimum STC rating of 45. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)23 XII Population and Housing a,b,c)Population in Palo Alto’s sphere of influence in 1996, according to Palo Alto Comprehensive Plan was 58,000 people. This is projected by the City’s Comprehensive Plan to increase to 62,880 by 2010. The project, by adding to the housing stock by 84 units, would cumulatively contribute to population in the area. The average household size in Palo Alto is 2.24 persons, which would mean the project could generate a total of 188 people. The projects cumulative impacts for the purposes of CEQA are also considered to be less than significant, as the impact from the project alone is not "considerable", and is di minimus, as environmental conditions would essentially be the same whether or not the project is implemented (as per CEQA Guidelines § 15355 and § 15064). This incremental increase in population generated by the proposed project would not be considered a significant impact. The project site is included as a Housing Opportunity Site in the Housing Element and the population increase is therefore expected. The project would remove an existing 50,468 square feet of vacant commercial space and Research and Development space to be replaced with 50,468 square feet of Research and Development space. This replacement of the existing R&D on the site would not be expected to increase population in the area. Residual Impact: Mitigation Measure: Less than significant impact. None required XIII Public Services Fire The proposed project would not impact fire service to the area and the site is not located in a high fire hazard area. The conditions of approval for the project contain requirements to address all fire prevention measures. Police The site is located within the jurisdiction of the Palo Alto Police Department. The expanded facility would not result in the need for additional police officers, equipment, or facilities. Schools Based on the Palo Alto Unified School District (PAUSD) student generation rates (Stanford Sand Hill Road Corridor Projects EIR, page 4.12-26) of 0.276 elementary students per residential unit, 0.088 middle school students, and 0.095 high school students, the project would generate 23 elementary students, 7 middle school students, and 8 high school students. Currently, enrollment in the PAUSD is approaching capacity. School overcrowding is not considered a significant effect however, under CEQA [Goleta Union School District v. The regents of the University of California (35 Cal.App.4th 1121 (1995)]. Rather, the increase in students from a project is only significant if such an increase would create significant environmental effects, such as impacts from the construction of a new school. Due to demand, the PAUSD is examining options to increase capacity, including re-opening currently closed schools. However, the project’s cumulative impacts for the purposes of CEQA are considered to be less than significant, as the impact from the project alone is not considerable. It should be noted that the PAUSD has implemented a school impact fee. Parks Impact fees to address impacts on parks were adopted by the Palo Alto City Council in March of 2002. Prior to receiving a building permit, the project applicant will be required to pay aone-time development impact fee for parks of $466,536.00. The fee will be used to offset impacts on park facilities as a result of this project. Therefore, the project would result in a less than significant impact. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)24 Other Public Facilities Impact fees to address impacts on community centers and libraries were adopted bythe Palo Alto City Council in March of 2002. Prior to receiving a building permiL the project applicant will be required to pay a one time development impact fee for community centers and libraries of $167,328.00. The fee will be used to offset impacts on community centers and library facilities as a result of this project. Therefore, the project would result in a less than significant impact. Residual Impact: Mitigation Measures: Less than significant impact. None required XIV. Recreation a,b)Palo Alto follows the National Recreation and Park Association Standards as guidelines for determining parkland needs. This requires two acres of parkland for each 1,000 people. The project could generate 188 additional persons, resulting in a demand of 0.19 acres of parkland. Impact fees to address impacts on parks were adopted by the Palo Alto City Council in March of 2002. Prior to receiving a building permit, the project applicant will be required to pay a one-time development impact fee for parks of $466,536.00. The fee will be used to offset impacts on park facilities as a result of this project. Therefore, the project would result in a less than significant impact. Residual Impact: Mitigation Measures: Less than significant impact None required XV.Transportation and Traffic a,b)A traffic report for the project was prepared by Fehr & Peers Associates, Inc. in May 2006. The report was prepared based upon a proposed project that included 84 residential units and approximately 50,468 square feet of Research and Development space that would replace 50,468 square feet of vacant Research and Development/Commercial space. The study was conducted following the guidelines set forth by the City of Palo Alto and the Valley Transportation Authority (VTA), which is the congestion management agency for Santa Clara County. Field observations by Fehr and Peers of the key intersections in the vicinity of the proposed project were conducted in September 2005. During the AM peak hour conditions, thePage Mill Road/Park Boulevard intersection operates with low delays (i.e vehicles wait less than 10 seconds) for the eastbound stop-controlled approach as vehicles exit Page Mill Road and turn either left or right onto Park Boulevard. Over the entire PM peak hour, the intersection operates at Level of Service (LOS) conditions with delays less than 25 seconds. Trip Reduction Factors The project will include both residential and employment land uses and is allowed atrip reduction factor based on the smaller trip generator. The proposed project may use a three percent reduction in the total estimated number of apartment-generated trips. In addition, because the proposed project is comprised of residential and employment facilities located within a 2,000-foot walking distance ofa Cal Train Station, reductions of nine percent and three percent, respectively, are allowed. The nine percent reduction is allowed for a residential land use located near a Cal Train station, and the three percent reduction is allowed for employment land use located near a Cal Train station. For the purpose of the TIA, no trip reduction was used for Park Plaza residents that also would work in the R&D space. The use of the above trip reduction factors would reduce the daily and peak hour project trip generation by approximately 12 percent. The proposed project is estimated to generate 577 net new Weekday daily trips, 40 net new AM peak-hour trips (8 inbound and/32 outbound) and 56 net new PM peak-hour trips (37 inbound/19 outbound). 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)25 Project Intersection Levels of Service The results of the LOS calculations for the With Project Condition were compared to the results of the Year 2008 Without Project Condition to identify significant project impacts. Based on the City of Palo Alto significance criteria for what would constitute as a significant project impact, the following six intersections were studied and it was determined that the proposed project would not have a significant impact on any of them. Foothill Expressway/Page Mill Road Hanover Street/Page Mill Expressway El Camino Real/Page Mill Expressway Middlefield Road/Oregon Expressway Park Boulevard/Page Mill Road E1 Camino Real/Charleston Road Residential Street Segment Analysis The proposed projects impacts on the local street Olive Avenue and Sheridan Avenue were also evaluated based on significance criteria developed by the City of Palo Alto. Based on the City of Palo Alto, a project would significantly impact a residential street if the proposed project would cause any change in traffic that would increase the Traffic Infusion of Residential Environment (TIRE) index by 0.1 or more on a local or collector residential street. Based on the City of Palo Alto significance criteria, the proposed project would not cause the TIRE index to increase by 0.1 or more on Olive Avenue or Sheridan Avenue. Therefore, the project would not significantly impact the local or collector streets of Olive Avenue or Sheridan Avenue. Conclusions *The proposed project would not significantly impact any of the six study sessions. *The proposed project would not significantly impact the local or collector residential streets of Olive Avenue or Sheridan Avenue. The two project driveways on Park Boulevard will operate at acceptable conditions during both the AM and PM peak hour conditions. The existing circulation on the Page Mill Road extension would be maintained by providing a 24 foot roadway width that would facilitate both two-way traffic and emergency response vehicles. With the 293 off-street parking spaces and nine additional parking spaces in landscape reserve, the proposed project will provide sufficient off-street parking spaces to serve peak parking demand and wil~ not impact on-street parking on Park Boulevard or the Page Mill Road Extension. With the supply of 112 bicycle parking spaces, the proposed project will provide sufficient parking to meet City of Palo Alto parking requirements and peak bicycle parking demand. The proposed project would not have a significant impact on freeway segments on US 101 or Interstate 280. The project applicant will pay to the City of Palo Alto Traffic Impact Fees based on the increased land use and adopted fee structure to improve mobility for all travel modes throughout the City. Based on the results of the TIA, it is recommended that the intersection remain unsignalized, with STOP control on the eastbound and westbound Page Mill Road approaches. When the adjacent parcel on Park Boulevard is developed, it is recommended that the need for a traffic signal be re-evaluated. Stafffurther concludes that, to assure parking and trip reduction are effective, a parking time-of-day study and a Transportation Demand Management (TDM) program should be proposed and implemented. 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)26 c) d,e) The project will not result in a change to air traffic patterns. The project has been reviewed by the City Fire Department and Transportation Division and does not contain design features that will substantially increase hazards or result in inadequate emergency access. Based on the parking requirements contained in Chapter 18.83 of the Palo Alto Municipal Code, the project will require 379 parking spaces. 302 parking spaces would be provided on site which includes 19 at grade spaces, 274 spaces in a subterranean parking garage, and 9 in landscaped reserve. Entrance to the underground facility would be located on Park Boulevard at approximately the midpoint of the building. The uses on the site require that 379 parking spaces are to be provided. The project would include both Research and Development and Residential use. PAMC Section 18.83.120(c) allows the Director of Planning and Community Environment, at his discretion, to approve up a 20% reduction for joint use facilities and up to a 20% for proximity to transportation alternatives. The applicant has requested a reduction of 23% or 86 spaces. Residual Impact:Implementation of the following mitigation measures would reduce the traffic and parking related impacts to a less than significant level. Mitigation Measures: MM #5 The 19 vehicle parking spaces and 12 Class III bicycle spaces in the surface parking lot will be designated as visitor parking. MM#6 A vehicle exiting/pedestrian warning system shall be implemented for the underground parking garage driveway to eliminate potential conflicts between vehicles and pedestrians/bicyclists. MM#7 A 130 foot left-turn pocket on northbound Park Boulevard will be implemented. This street cross- section will include the following travel lanes: o 7 foot on-street parking; ¯5 foot southbound bicycle lanes; ¯10.5 foot southbound travel lane ¯10 foot northbound left-turn lane ¯10.5 foot northbound travel lane; and ¯5 foot northbound bicycle lane. MM #8 A parking study demonstrating time-of-day parking for the different land uses and documenting that the reduced parking request is justified and that "shared" spaces will be available to accommodate the parking demand shall be prepared and submitted for review and approval by staff. MM #9 A Transportation Demand Management Plan (TDM) program indicating measures to be implemented and enforced to encourage use of transit or other non-vehicular transportation modes for residents and employees of the site shall be prepared and submitted for review and approval by staff. XVI. Utilities and Service Systems a-g)The proposed project will increase the demand on existing utility and service systems. The project would require new and expanded electrical, communication, water, and sewer connections. However, the improvements would be considered minor improvements to the existing systems, and is therefore a less than significant impact. The project 195 Page Mill Road, 2825, 2865, 2873, & 2901 Park Boulevard, File No. 05-PLN-00281)27 could create minor discharges of pollutants in the form of automobile and landscaping maintenance. However, conditions of approval associated with the project would reduce any impacts to a less than significant level. The project would also require new solid waste disposal services from the Palo Alto Sanitation company, but would not require new :equipment or substantial alteration to present service and is therefore a less than significant impact. The project would not be expected to greatly increase water demand. No new sources of water would need to be found. The City uses an average of 13 million gallons a day (mgd) in 1996 and the projected water demand in the City is not expected to exceed 13.7 mgdthrough 2007. Currently, the City has a guaranteed allocation of 17 mgd through the year 2006 from the Hetch Hetchy water system. Therefore, the project would result in a less than significant impact. Residual Impact: Less than significant impact Mitigation Measures: None required MANDATORY FINDINGS OF SIGNIFICANCE The project would not have an impact on fish or wildlife habitat, nor would it impact cultural or historic resources. The uses are appropriate for the site and the development would not result in an adverse visual impact. There is nothing in the nature of the proposed development and property improvements that would have a substantial adverse effect on human beings, or other life or environmental impacts, subject to the implementation of mitigation measures 1-8.

Redesign the rear of the building to comply with a daylight plane of 16 feet in height as measured at the rear property line with an angle of 45 degrees, and with at least two breaks in the 450 foot continuous wall at three stories, with minimum 50 foot sections of wall height not to exceed 25 feet in height. I. Redesign the Park Boulevard frontage to provide a commercial pedestrian-oriented facade with frequent door openings, awnings, and street-furniture. MM #3 Prior to issuance of any building permit or grading permit, reports documenting the location of hazardous waste contaminants in the soil and/or groundwater shall be provided to the SCVWD and RWQCB for review and project approval, if required. Written confirmation from the San Francisco Bay Regional Water Quality Control Board (Regional Board) shall be submitted to the City, either 1) indicating that no contamination exists; or 2) that the proposed construction and site activities, including underground parking, dewatering sumps or wells will not result in exposure of workers or the public to those contaminants and that such construction will not have an adverse impact on the ongoing or future groundwater cleanup efforts; or 3) mitigation measures to be reviewed and approved by the Regional Board will provide adequate protection from exposure. A Risk Management Plan shall be submitted to and must be approved by the Regional Board, if required. If contamination does not exist beneath the subject property, the applicant shall provide information regarding the lateral distance to existing groundwater contamination plumes and an analysis of the potential impacts to those plumes from construction activity on the subject property, including the use of dewatering sumps or wells under the proposed underground parking structure. This information shall be submitted to the Regional Board for approval that the proposed work on the subject property, including any use of dewatering sumps or wells will not have an adverse impact on the current and future cleanup efforts. The approval shall verify that dewatering sumps or wells, if proposed, would not alter the path of the groundwater contamination plume(s) and could not result in bringing groundwater contamination to the subject property or a possible future exposure of the public on the subject property to groundwater contaminants. MM #4 The project shall include design features to reduce the maximum indoor noise level to as close as the 45dB standard as feasible through project design. To achieve this, STC rated exterior walls facing the Caltrain shall have an STC rating of at least 50. Exterior glazing for bedrooms facing CalTrain shall have a minimum STC rating of 45. MM #5 The 19 vehicle parking spaces and 12 Class III bicycle spaces in the surface parking lot will be designated as visitor parking.
