HomeMy WebLinkAboutStaff Report 364-09City of Palo Alto City Manager's Report TO: HONORABLE CITY COUNCIL FROM: CITY MANAGER DATE: SEPTEMBER 21, 2009 REPORT TYPE: CONSENT DEPARTMENTS: CITY CLERK AND PLANNING AND COMMUNITY ENVIRONNIENT CMR: 364:09 SUBJECT: Approval of a Negative Declaration and Adoption of an Ordinance Amending Title 21 (Subdivisions) and Title 18 (Zoning) of the Palo Alto Municipal Code to Define the Minimum Width for Private Streets and Excluding Private Streets from the Calculation of Floor Area RECOMMENDATION Staff recommends that the City Council: 1. Approve the proposed Negative Declaration (Attachment B); and 2. Adopt the proposed ordinance amendments (Attachment A) defining the minimum width of private streets and excluding the area of private streets from the calculation of lot size. BACKGROUND A proposed initiative to provide minimum widths for private streets (Initiative) qualified for the November ballot, according to the certification of the Santa Clara County Registrar of Voters on July 15, 2009. On July 27-, 2009, the City Council voted to direct staff to prepare the ordinance for adoption and to prepare the associated environmental review, both to return to the Council on September 21,2009. This action negated the need to place the measure on the November ballot. DISCUSSION The draft ordinance amendments are included as Attachment A, and reflect verbatim the language of the Initiative. The intent of the proposed ordinance, as stated in the Initiative language, is to address concerns about vehicle circulation on private streets (particularly for fire and garbage trucks), inclusion of streets in determining lot size and floor area, and overflow traffic and;parking onto nearby residential streets. The specific provisions of the Initiative would amend the Subdivision Ordinance of the City to: • Generally limit private street width to a minimum of 32 feet (as compared to a public street width of 40 feet); CMR: 364:09 Page 1 of3 • Allow lesser width at a minimum of 26 feet where either a) at least a 6-foot parking strip is provided adjacent to the street or b) homes are set back at least 20 feet from the street; • Allow lesser width at a minimum of 22 feet where the street serves 4 or fewer lots; • Provide that all of those widths are "minimums" and the streets must be shown to be adequate to the satisfaction of the Director of Planning and Community Environment and, for widths less than 32 feet, by the City Council; and • Exclude the area of private streets from the calculation of Floor Area Ratio for determining allowable development. Additionally, the definition of "Lot area" would be amended in the Zoning Ordinance to exclude "public or private" street right-of-way (current code interpretations only exclude public right-of- way). This would again further limit the floor area allowed on a site. If the attached ordinance is adopted, no second reading is required according to the City Charter and State law regarding adopting ordinances generated by initiative. The ordinance would then become effective on October 22,2009 (31st day after the adoption). The Initiative indicates an effective date of July 31, 2009, but notes that, if the retroactive date is voided or otherwise deemed unenforceable by judicial action, then November 4, 2009 would be the effective date. The City Attorney has noted that the retroactive provision of the Initiative is not likely to be defensible, so that November 4 would be the operative effective date. Applicability and Enforceability of Ordinance In order to avoid the costs of an election, the Council directed that the Initiative ordinance be adopted exactly as written. The City Attorney has indicated that the retroactive provision is unenforceable, but it would not nullify the ordinance if adopted as written because the ordinance contains a severability clause that would leave all legally enforceable portions of the ordinance intact. Using the City's current definition of private streets, however, the initiative would apply only to non-dedicated streets which are on a "separate parcel of land used for ingress to or egress from two or more lots which do not have the minimum street frontage" or non-dedicated streets that provide access to one lot that does not meet minimum street frontage "if the parcel of land used for ingress or egress is more than two hundred feet in length." Because this definition predates enactment of the Davis-Stirling Common Interest Development Act, it is unlikely that any future development will propose vehicular access in a way that would meet the City's definition of private streets. As such, absent further clean-up, the initiative would not have any direct impact on any project currently in the planning or development process. The ordinance will have no impact upon the Alma Plaza development as the tentative map was already passed by the Council long before the initiative. Due to the improper definition, it is the City Attorney' sopinion that the ordinance will have no impact upon any current application including t,he proposed Palo Alto Bowl project. Potential Revisions to the Ordinance Staff has met with the Initiative sponsor and believes that a few revisions to the City's subdivision ordinance, in particular the definition of "private streets," would allow for effective implementation of the intent of the Initiative. Subsequent to adoption of the Initiative ordinance, CMR: 364:09 Page 2 of3 staff will prepare further subdivision code amendments to make those clarifications to better realize the intent of the Initiative. Staff believes the amendments could be made in a way that does not affect the Initiative ordinance and would not therefore require a public vote. Staff expects to provide those amendments to the Planning and Transportation Commission in October and the City Council in November. POLICY IMPLICATIONS The Initiative specifically calls out Comprehensive Plan Policies C30, L17, T23, and T25, as well as Programs T33 and T53, which would be enhanced by the ordinance. Staff concurs that those policies and programs are further supported by the proposed standards. ENVIRONMENTAL REVIEW Pursuant to the provisions of the California Environmental Quality Act (CEQA), a Negative Declaration has been prepared and is included as Attachment B to be adopted by Council. RESOURCE IMPACT The costs of the ordinance are anticipated to be negligible, since· the costs of construction and maintenance of private streets will be borne by project developers and subsequent owners and homeowners' associations.

The City Council finds as follows: A. On July 15, 2009, an initiative petition defining the minimum width of private streets and excluding private streets from the calculation of floor area was certified by the Santa Clara County Registrar of Voters as qualified to be submitted to voters on the November 2009 ballot. B. On July 27, 2009, the City Council directed that the City should adopt the ordinance amendments proposed in the initiative petition rather than placing the initiative on the November 2009 election ballot. C. The Council finds that the ordinance amendments further the public interest, health and welfare of the community and are consistent with the Comprehensive Plan. SECTION 3. The City Council hereby amends Section 18.04.030(a)(85) to read as follows: (85) "Lot area" means the area of a lot measured horizontally between bounding lot lines, but excluding any portion of a flag lot providing access to a street and lying between a front lot line and the street, and excluding any portion of a lot within the lines of any natural watercourse, river, stream, creek, waterway, channel, or flood control or drainage easement and excluding any portion of a lot within a public or private street right-of-way whether acquired in fee, easement, or otherwise. SECTION 4. The City Council hereby amends Section 21.040.030(a)(30) to read as follows: (30) "Private street" means any parcel of land not dedicated as a public street wliich is used for ingress and egress from two or more lots which do not have the required minimum frontage on a public street, or to or from one lot which does not have the required minimum frontage on a public street if the parcel of land used for ingress or egress is more than two hundred feet in length. Private streets shall be excluded for the purpose of determining Floor Area Ratio (FAR). Minimum width of "private streets" shall be as defined in 21.20.240Cb)(4). 1 090916 syn 0120405 NOT YET APPROVED SECTION 5. The City Council hereby amends Section 21.040.240(b)(4) to read as follows: (4) Private streets: Such right-of-way as would be required for a comparable public street, except as specified below. unless sabdivider caa de:moastrate to the satisfaetioa of the city cooocil Of director of planniag aoo eommooity ea'lirol'lfB:eB:t. as apflroflriate, facts relatiag to the aature or locatioa of the flroposed stireet or tae aature of the proposed de·;elopmeat which reader such rigat of vlay l:lfllleeessary fOf or detrimental to the pablie health. safety or vf'elfure. Streets serving five or more lots shall be no less than thirty two feet wide. Streets serving four or fewer lots shall be no less than twenty two feet wide providing that the Director of Planning and Community Environment and the City Council specifically approves the twenty two foot street width. (a) If a building adjacent to a private street has a setback of at least 20 feet between the street and building allowing on-site parking, then the width of the private street may be no less than twenty six feet at the discretion of the Director of Planning and Community Environment and the City Council. (b) If a private street has a public parking strip of at least six feet in width between the street and the building location, then the width of the private street may be no less than twenty six feet at the discretion of the Director of Planning and Community Environment and the City Council. Effective Date: This private street width requirement applies to any project or development that has not obtained a final map, building permit. and performed significant construction as of July 31. 2009. If the effective date of July 31, 2009 is held by a court of competent jurisdiction in a final judicial action to be void, voidable. or unenforceable. then the effective date of this ordinance as it applies to private street width shall be November 4, 2009. SECTION 6. Severability. If any section of this initiative ordinance, or part hereof, is held by a court of competent jurisdiction in a final judicial action to be void, voidable. or unenforceable, such section or part hereof, shall be deemed severable from the remaining sections of this initiative ordinance and shall in no way affect the validity of the remaining sections hereof SECTION 7. The Council hereby finds that this rezoning is subject to environmental review under the provisions of the California Environmental Quality Act (CEQA). An environmental assessment was prepared for the project and it has been determined that no potentially adverse impacts would result from the rezoning of the property; therefore, the project would have no significant impact on the environment.

The proposed Ordinance includes the following amendments to the Subdivision Ordinance: -For streets serving five or more lots the width shall be a minimum of a 32 feet (as compared to a public street width of 40 feet); -For streets serving four Qf fewer lots the width shall be a minimum of a 22 feet; -Allow lesser width at a minimum of 26 feet where either a) at least a 6-foot parking strip is provided adjacent to the street or b) homes are set back at least 20 feet from the street allowing on-site parking; -Provide that all of the proposed widths are "minimums" and the streets must be shown to be adequate to the satisfaction of the Director of Planning and Community Environment and, for widths less than 32 feet, by the City Council; and -Exclude the area of private streets from the calculation of Floor Area Ratio for determining allowable development. Additionally, the definition of "Lot area" would be amended in the Zoning Ordinance to exclude "public or private" ~treet right-of-way (current code interpretations only exclude public right-of-way). This would further limit the floor area allowed on a site. II. DETERMINA TION 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 could have a significant effect on the environment. On the basis of that study, the City makes the following determination: X The proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION is hereby adopted. 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.

PROJECT SPONSOR City of Palo Alto Department of Planning 'and Community Environment 5. PROJECT LOCATION The proposed Ordinance would apply to designated development projects that create private streets within the City of Palo Alto. Palo Alto is located in the northern part of Santa Clara County in the portion of the Bay Area known as the Mid-Peninsula. The City shares a boundary with San Mateo County and six cities and is approximately 35 miles south of San Francisco and 14 miles north of San Jose. 6. GENERAL PLAN DESIGNATION r I The Ordinance would apply city-wide. The Comprehensive Plan policies and programs that support the project include the following: • POLICY C-30: Facilitate access to parks and community facilities by a variety of transportation modes. Ordinance to Specify Minimum Widths for Private Streets Page I Negative Declaration • POLICY L-17: Treat residential streets as both public ways and neighborhood amenities. Provide continuous sidewalks, healthy street trees, benches, and other amenities that favor pedestrians. • POLICY T -23: Encourage pedestrian-friendly design features such as sidewalks, street trees, on-street parking, public spaces, gardens, outdoor furniture, art, and interesting architectural details. • POLICY T-25: When constructing or modifying roadways, plan for usage of the roadway space by all users, including motor vehicles, transit vehicles, bicyclists, and pedestrians. • PROGRAM T -33: Develop comprehensive roadway design standards and criteria for all types of roads. Emphasize bicycle and pedestrian safety and usability in these standards. • PROGRAM T-53: Discourage parking facilities that would intrude into adjacent residential neighborhoods. 7. ZONING The Ordinance applies city-wide and does not conflict with purposes of the Zoning code, which include the promotion and protection of public heath, safety, peace, morals, comfort, convenience, and general welfare. 8. PROJECT DESCRIPTION Background . The intent of the proposed Ordinance is to address concerns about inadequate vehicle circulation on private streets (particularly for fife and garbage trucks), the inclusion of street area in determining lot size and therefore allowing larger floor areas, and the impacts from overflow traffic and parking onto nearby residential streets. Proposed Project The City of Palo Alto proposes to amend Palo Alto Municipal Code sections l8.04.030(a)(85), 21.04.030(a)(30) and 21.20.240(b)(4) regarding private streets to specify minimum widths and to exclude private streets from the related project's floor area calculation. The proposed Ordinance includes the following amendments to the Subdivision Ordinance: • For streets serving five or more lots the width shall be a minimum of a 32 feet (as compared to a public street width of 40 feet); • For streets serving four or fewer lots the width shall be a minimum of a 22 feet; • Allow lesser width at a minimum of 26 feet where either a) at least a 6-foot parking strip is provided adjacent to the street or b) homes are set back at least 20 feet from the street allowing on-site parking; • Provide that all of the proposed widths are "minimums" and the streets must be shown to be adequate to the satisfaction of the Director of Planning and Community Environment and, for widths less than 32 feet, by the City Council; and . • Exclude the area of private streets from the calculation of Floor Area Ratio for determining allowable development. Additiopally, the definition of "Lot area" would be amended in the Zoning Ordinance to exclude "public or private" street right-of-way (current code interpretations only exclude public right-of-way). This would further limit the floor area allowed on a site. The proposed Ordinance would apply to any project or development that has not obtained a final map and building permit, and performed significant construction as of July 31, 2009.

The City is situated within a developed urban area with mUltiple cities adjacent to the city limits. 10. OTHER PUBLIC AGENCY APPROVALS REQUIRED None ENVIRONMENTAL CHECKLIST AND DISCUSSION OF IMPACTS EVALUATION OF ENVIRONMENTAL IMPACTS 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. [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 effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "(Mitigated) 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 (C)(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. Ordinance to Specify Minimum Widths Private Streets Page 3 Negative Declaration 6) Lead agencies are encouraged to incorporate into the checklist references to infonnation 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 Infonnation Sources: A source list should be attached,and other sources used or individuals contacted should be cited in the discussion. 8) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evalu~te each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance. DISCUSSION OF IMPACTS The following Environmental Checklist was used to identify environmental impacts, which could occur if the proposed project is implemented. The left-hand column in the checklist lists the source(s) for the answer to each question. The sources cited are identified at the end of the checklist. Discussions of the basis for each answer and a discussion of mitigation measures that are proposed to reduce potential significant impacts are included. A. AESTHETICS Issues and Supporting Information Sources Potentially Potentially Less Than No Resources Significant Significant Significant Impact Issues Unless Impact Would the project: Mitigation Incorporated a) Substantially degrade the existing visual 1,2,3,4 X character or quality of the site and its surroundings? b) Have a substantial adverse effect on a 1,2-Map X , public view or view corridor? L4,3,4 c) Substantially damage scenic resources, 1,2-Map X including, but not limited to, trees, rock L4,3,4 outcroppings, and historic buildings within a state scenic highway? d) Violate existing Comprehensive Plan 1, 2, 3, 4 X policies regarding visual resources? e) Create a new source of substantial light or 1,4 X glare which would adversely affect day or nighttime views in the area? t) Substantially shadow public open space 1,4 X (other than public streets and adjacent sidewalks) between 9:00 a.m. and 3:00 p.m. from September 21 to March 21? DISCUSSION: All individual projects proposed that would be impacted by the Ordinance would be subject to discretionary design review by the City. The review is intended to promote visual environments that are of high aesthetic quality and to assure that use and development will be hannonious with other uses in the general vicinity, and will be in accord with the Palo Alto Comprehensive Plan. Ordinance to Specify Minimum Widths for Private Streets Page 4 Negative Declaration The proposed Ordinance will not create any new aesthetic impacts. All individual proposed projects are subject to review to address aesthetics and the required CEQA analysis will be completed on a case-by-case basis to determine potential impacts. Mitigation Measures: None Required B. AGRICULTURAL RESOURCES In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Would the project: Issues Unless Impact Mitigation Incorporated a) Convert Prime Farmland, Unique Farmland, 1,2,4 X or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b) Conflict with existing zoning for agricultural 1,2-X use, or a Williamson Act contract? MapL9,4 c) Involve other changes in the existing 1,2-X environment which, due to their location or MapL9,4 nature, could result in conversion of Farmland, to non-agricultural use? DISCUSSION: The proposed Ordinance does not encourage development nor change the existing uses that have been established throughout the City and therefore is anticipated to have no impacts on agricultural resources. Mitigation Measures: None Required C. AIR QUALITY Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Would the project: Issues Unless Impact Mitigation Incorporated a) Conflict with or obstruct with implementation X of the applicable air quality plan (1982 Bay 1,4 Area Air Quality Plan & 2000 Clean Air Plan)? b) Violate any ai{quality standard or contribute ;'i, <, substantially to an existing or projected air ' , ,,' quality violation indicated by the following: , " i. Direct and/or indirect operational 1,4 X emissions that exceed the Bay Area Air Quality Management District (BAAQMD) criteria air pollutants of 80 pounds per day Ordinance to Specify Minimum Widths for Private Streets Page 5 Negative Declaration Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Would the project: Issues Unless Impact Mitigation Incorporated and/or 15 tons per year for nitrogen oxides (NO), reactive organic gases (ROG), and fine particulate matter of less than 10 microns in diameter (PMIO); ii.

Not implement all applicable construction 1,4 X emission control measures recommended in the Bay Area Air Quality Management District CEQA Guidelines? DISCUSSION: The City of Palo Alto is located within the jurisdiction of the Bay Area Air Quality Management District (BAAQMD), the regional agency empowered to regulate air pollutant emissions from stationary sources in the Bay Area. The BAAQMD regulates air quality through its permit authority over most types of stationary emission sources and through its planning and review process. All development in Palo Alto is subject to the BAAQMD regulations. The proposed revisions to the Palo Alto Municipal Code will not create any new air quality impacts. All individual proposed projects will be reviewed for impacts and are subject to CEQA.

Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Wonld the project: Issues Unless Impact Mitigation Incorporated a) Have a substantial adverse effect, either 1, 2~ X directly or through habitat modifications, on MapNl, any species identified as a candidate, sensitive, 3,4 or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? . b) Have a substantial adverse effect on any 1,2-X riparian habitat or other sensitive natural MapNl, community identified in local or regional plans, 3,4 policies, regulations, including federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? c) Interfere substantially with the movement of 1,2-X any native resident or migratory fish or wildlife MapNl, species or with established native resident or 3,4 migratory wildlife corridors, or impede the use of native wildlife nursery sites? d) Conflict with any local policies or ordinances 1,3,4,9 X e) protecting biological resources, such as a tree preservation policy or as defined by the City of Palo Alto's Tree Preservation Ordinance (Municipal Code Section 8.1O)? Conflict with any applicable Habitat 1,2,4 X Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? DISCUSSION: The City of Palo Alto, with its various developed and open space areas, provides habitat for a broad range of wildlife and plants, including some designated as protected or sensitive either by the State of California or through Federal designation. All development projects are subject to design review in addition to the environmental review (CEQA) to ensure an environmentally sensitive project is approved. The proposed Ordinance will ))fot create any new biological impacts. Mitigation Measures: None Required Ordinance to Specify Minimum Widths for Private Streets Page 7 Negative Declaration E. CULTURAL RESOURCES Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Would the project: Issues Unless Impact Mitigation Incorporated i a) Directly or indirectly destroy a local cultural 1,4, 10 X resource that is recognized by City Council resolution? b) Cause a substantial adverse change in the 1,2-X significance of an archaeological resource MapL8, pursuant to 15064.5? 4 i c) Directly or indirectly destroy a unique 1,2-X paleontological resource or site or unique MapL8, geologic feature? 4 d) Disturb any human remains, including those 1,2-X e) f) interred outside of formal cemeteries?

Eliminate important examples of major periods 1,2,4 X of California history or prehistory? DISCUSSION: The majority of the City of Palo Alto is considered to have areas with low to moderate sensitivity for archaeological resources, with a few pockets of extreme sensitivity. For all projects, if during grading and construction activities, any archaeological or human remains are encountered, construction shall cease and a qualified archaeologist shall visit the site to address the find. The Santa Oara 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 proposed Ordinance will not create any cultural impacts to the affected area. All individual proposed projects are subject to CEQA and will be evaluated on a case-by-case basis for potential impacts. Mitigation Measures: None Required F. GEOLOGY, SOILS AND SEISMICITY Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Wc{uld the project: Issues Unless Impact Mitigation Incorporated a) Expose people or structures to potential , " ' " ""'>""" """ ,", " substantial adverse effects, including the risk of loss, injury, or death involving: '" i) Rupture of a known earthquake fault, 4,6 X Ordinance to Specify Minimum Widths for Private Streets Page 8 Negative Declaration I as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault?

DISCUSSION: The City of Palo Alto would experience a range from weak to very violent shaking in the event of a major earthquake along the San Andreas or Hayward fault. Although hazards exist, development would not expose people or property to major geologic hazards that cannot be addressed through the use of standard engineering design and seismic safety techniques, as required by building codes. With proper engineering new development is not expected to Jesuit in any significant adverse short or long-term impacts related to geology, soils or seismicity. I The proposed Ordinance will not create any new geology, soils and seismicity impacts.

All development projects are required to implement Best Management Practices (BMPs) for construction activities as specified by the California Storm Water Best Management Practices Handbook (CASQA, 2(03) and/or the Manual of Standards for Erosion and Sediment Control Measures (ABAG, 1995). The BMPs include measures guiding the management and operation of construction sites to control and minimize the potential contribution of pollutants to storm runoff from these areas. These measures address procedures for controlling erosion and sedimentation and managing all aspects of the construction process to ensure control of potential water pollution sources. All development projects must comply with all City, State and Federal standards pertaining to storm water run-off and water quality. The proposed Ordinance will not create any new hydrology and water quality impacts. All individual proposed projects are subject to CEQA and will be evaluated on a case-by-case basis for potential impacts. Mitigation Measures: None Required I. LAND USE AND PLANNING Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Would the project: Issues Unless Impact Mitigation Incorporated a) Physically divide an established community? 1,4 X b) Conflict with any applicable land use plan, 1,2,3,4 X policy, or regulation of an agency with jurisdiction over the project (incIl.!ding, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat 1,2,4 X conservation plan or natural community conservation plan? d) Substantially adversely change the type or 1,2,4 X intensity of existing or planned land use in the area? e) Be incompatibly with adjacent land uses or with 1,2,3,4 X the general character of the surrounding area, including density and building height? f) Conflict with established residential, 1, 2,3,4 X recreational, educational, religious, or scientific uses of an area? g) Convert prime farmland, unique farmland, or 1,2-X Ordinance to MinlmumWidths Private Streets Page 12 Negative Declaration a) Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Significant Significant Significant Impact Would the project: Issues Unless Impact Mitigation Incorporated farmland of statewide importance (farmland) to MapL9, non-agricultural use? 4 DISCUSSION: The proposed Ordinance is not anticipated to create any new land use impacts. The Ordinance eliminates using the area dedicated to private streets from a project's floor area calculation, which in tum would reduce the area/mass of the related project, and potentially provide additional street parking. This is not considered a significant impact because it does not prevent development; developers would need to adjust their projects accordingly to accomplish the overall project goals. Compliance with the designated land uses and zoning is a requirement for all development. All individual proposed projects are subject to CEQA and will be evaluated on a case-by-case basis for potential impacts. Mitigation Measures: None Required J.

X b) Result in the loss of availability of a locally- a) important mineral resource recovery site 1,2 delineated on a local general plan, specific plan X or other land use plan? DISCUSSION: The City of Palo Alto has been classified by the California Department of Conservation (DOC), Division of Mines and Geology (DMG) as a Mineral Resource Zone 1 (MRZ-1). This designation signifies that there are no aggregate resources in the area. The DMG has not classified the City for other resources. There is no indication in the 2010 Comprehensive Plan that there are locally or regionally valuable mineral resources within the City of Palo Alto. Mitigation Measures: None Required. K. NOISE Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Impact Significant Significant Significant Would the project: Issues Unless Impact Mitigation Incorporated Exposure of persons to or generation of noise 1,2,4 X Ordinance to Specify Minimum Widths for Private Streets Page 13 Negative Declaration Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Impact Significant Significant Significant Would the project: Issues Unless Impact Mitigation Incorporated levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b) Exposure of persons to or generation of 1,2,4 X excessive ground borne vibrations or ground borne noise levels? c) A substantial permanent increase in ambient 1,2,4 X noise levels in the project vicinity above levels existing without the project? d) A substantial temporary or periodic increase in 1,2,4 X ambient noise levels in the project vicinity above levels existing without the project? e) For a project located within an airport land use 1,2,'4 -X plan or, where such a plan has not been adopted, would the project expose people residing or working in the project area to excessive noise levels? f) For a project within the vicinity of a private 1;4 X airstrip, would the project expose people residing or working in the project area to excessive noise levels? g) Cause the average 24 hour noise level (Ldn) to 1,4 X increase by 5.0 decibels (dB) or more in an existing residential area, even if the Ldn would remain below 60 dB? h) Cause-the Ldn to increase by 3.0 dB or more in 1,4 X i) j) k) 1) an existing residential area, thereby causing the Ldn in the area to exceed 60 dB? Cause an increase of 3.0 dB or more in an 1,4 X existing residential area where the Ldn currently exceeds 60 dB?

Generate construction noise exceeding the 1,4 X daytime background Leq at sensitive receptors by 10 dBA or more? DISCUSSION: All development, including construction activities, must comply with the City's Noise Ordinance (PAMC Chapter 9.10), which r¢"stricts the timing and overall noise levels associated with construction activity. Short-term construction that complies with the Noise Ordinance would result in impacts that are expected to be less than significant. The proposed Ordinance will not create any new noise impacts. All individual proposed projects are subject to CEQA and will be evaluated on a case-by-case basis for potential impacts.

The minimum private street width should improve safety because it provides consistent standards that meet emergency vehicle and garbage. truck access requirements. The. Ordinance is anticipated to increase street parking as applicable and thereby reducing spillover parking into adjacent neighborhoods. The proposed Ordinance does not encourage growth and development and is not anticipated to generate transportation impacts. All individual proposed projects are subject to CEQA and will be evaluated on a case-by-case basis for potential impacts. Mitigation: None Required P.

DISCUSSION: The proposed Ordinance does not encourage growth and development and therefore no significant increase in the demand on existing utilities and service systems or impacts to these services are expected. All individual proposed projects are subject to CEQA and will be evaluated on a case-by-case basis for potential impacts. Mitigation Measures: None Required Q. MANDATORY FINDINGS OF SIGNIFICANCE Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Impact Significant Significant Significant Would the project: Issues Unless Impact Mitigation Incorporated a) Does the project have the potential to 1,2,3,4 X degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are 1,2,3,4 X c) individually limited, but cumulatively considerable? C"Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? Does the project have environmental effects 1,2,3,4 X which will cause substantial adverse effects on human beings, either directly or indirectly? DISCUSSION: The City of Palo Alto, with its various developed and open space areas, provides habitat for a broad range of wildlife and pllnts, including some designated as protected or sensitive either by the State of California or through Federal designation. All development projects are subject to design review in addition to the environmental review (CEQA) to ensure an environmentally sensitive project is approved. The proposed Ordinance will not create any additional biological impacts. Ordinance to Specify Minimum Widths for Private Streets Page 19 Negative Declaration The proposed amendments to the Palo Alto Municipal Code are not anticipated to degrade the quality of the environment or create environmental effects that would adversely impact human beings. The proposed Ordinance is not anticipated to have cumulatively considerable impacts. Global Climate Change Impacts Global climate change is the alteration of the Earth's weather including its temperature, precipitation, and wind patterns. Global temperatures are affected by naturally occurring and anthropogenic generated atmospheric gases, such as carbon dioxide, methane, and nitrous oxide. These gases allow sunlight into the Earth's atmosphere, but prevent radiative heat from escaping into outer space, which is known as the "greenhouse" effect. The world's leading climate scientists have reached consensus that global climate change is underway and is very likely caused by humans. Agencies at the international, national, state, and local levels are considering strategies to control emissions of gases that contribute to global warming. There is no comprehensive strategy that is being implemented on a global scale that addresses climate change; however, pursuant to Senate Bill 97 the Governor's Office of Planning and Research (aPR) is in the .process of developing CEQA guidelines "for the mitigation of greenhouse gas emissions or the effects of greenhouse gas emissions." aPR is-required to "prepare, develop, and transmit" the guidelines to the Resources Agency on or before July 1,2009. The Resources Agency must certify and adopt the guidelines on or before January 1,2010. Assembly Bill 32 requires achievement by 2020 of a statewide greenhouse gas emissions limit equivalent to 1990 emissions, and the adoption of rules and regulations to achieve the maximum technologically feasible and cost- effective greenhouse gas emissions reductions. By 2050, the state plans to reduce emissions to 80 percent below 1990 levels. While the state of California has established programs to reduce greenhouse gas emissions, there are no established standards for gauging the significance of greenhouse gas emissions; these standards are required to be in place by 2012. Neither CEQA nor the CEQA Guidelines provide any methodology for analysis of greenhouse gases. Given the "global" scope of global climate change, the challenge under CEQA is for a Lead Agency to translate the issue down to the level of a CEQA document for a specific project in a way that is meaningful to the decision making process. Under CEQA, the essential questions are whether a project creates or contributes to an environmental impact or is subject to impacts from the environment in which it would occur, and what mitigation measures are available to avoid or reduce impacts. . Although greenhouse gas emissions (GHG) generated by future development projects in the Open Space district, as allowed under the Comprehensive Plan, would cumulatively contribute to global climate change, the City's regulations supports development while preserving and conserving natural areas. In addition, the City has adopted green building regulations that apply to all development projects, residential and otherwise, which further facilitates the reduction of the GHG emissions of all projects. The proposed Ordinance would not make a cumulatively considerable contribution to global climate change associated with greenhouse gas emissions. All individual proposed projects in the will be evaluated on a case-by-case basis for its potential impacts.

X 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. I find that the proposed project MA Y have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MA Y 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 significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DE CLARA TION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARA TION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.
