The total building area would be 110,602 square feet, which would also include the square footage of Building 1 (7,611 square feet), which was an existing building on an adjacent lot that was purchased by the School in 1997 and made a part of the school campus. The added total building area is referred to herein as the "Project"; and WHEREAS, a complete application for the Project is available and on file in the Dublin Planning Department; and WHEREAS, environmental review for the Project area was previously conducted and documented in the certified EIR for the Eastern Dublin General Plan Amendment and Specific Plan, which was adopted in 1993 (SCH No. 91-103064) and in the certified EIR for the Quarry Lane Master Plan, which was adopted in 1998 by the County of Alameda (SCH No. 97122109); and WHEREAS, in 2000, the City of Dublin approved a Planned Development District Stage 1/2 Development Plan for the construction of Phase I I of Quarry Lane School, and adopted a Mitigated Negative Declaration (City Council Resolution 204-00, incorporated herein by reference); and WHEREAS, in 2004, the Planning Commission approved Site Development Review, a Conditional Use Permit, and adopted a CEQA Addendum to allow the construction of Phase II of Quarry Lane School and the associated minor amendments to the approved Development Plan (PC Resolution 04-46, incorporated herein by reference); and WHEREAS, pursuant to CEQA Guidelines Section 15162, the City of Dublin prepared an Initial Study to determine if additional environmental review was required for the Project beyond the prior EIRs and Mitigated Negative Declaration. The Initial Study determined that the project would not require major revisions to the previous EIRs or Mitigated Negative Declaration because the Project would not have new significant environmental effects or a substantial increase in the severity of previously identified significant effects. Because the overall site building envelope, amount of urbanized area, and student and staff population were unchanged, the impacts and appropriate mitigations are the same and no new mitigations are required. Furthermore, the Initial Study determined that there was no change in circumstances that would result in new significant environmental effects or a substantial increase in the severity of previously identified significant effects because no new or unanticipated circumstances have developed since the previous EIRs were certified, the previous Mitigated Negative Declaration was adopted, and the previous Addendum was adopted; and WHEREAS, pursuant to CEQA Guidelines Section 15164 and based on the Initial Study, dated April 28, 2014, the City prepared an Addendum to the prior CEQA documents. The Addendum with its supporting Initial Study are attached to this Resolution as Exhibit A, which is incorporated herein by reference and which describes the Quarry Lane School Phase III expansion and its relation to the analysis in the previous environmental documents; and WHEREAS, a Staff Report, dated May 13, 2014 and incorporated herein by reference, described and analyzed the Quarry Lane School Phase III expansion, including the Site Development Review application and the proposed Planned Development Rezoning/Development Plan amendment, for the Planning Commission; and WHEREAS, the Planning Commission held a properly noticed public hearing on the Project, including the proposed Site Development Review application and the proposed Planned Development Rezoning/Development Plan amendment, on May 13, 2014, at which time all interested parties had the opportunity to be heard; and WHEREAS, the Planning Commission considered the CEQA Addendum, all above- referenced reports, recommendations, and testimony to evaluate the Project. NOW, THEREFORE, BE IT RESOLVED that the foregoing recitals are true and correct and made a part of this resolution. BE IT FURTHER RESOLVED THAT the Planning Commission has reviewed and considered the Addendum dated April 28, 2014 (Exhibit A) prior to making a recommendation on the Project. BE IT FURTHER RESOLVED THAT the Planning Commission recommends that the City Council adopt a Resolution adopting the attached Addendum to the previous environmental documents for the Quarry Lane School Phase III expansion project.

Construction of a new two story, 13,102 square foot cafeteria and science building behind the existing office/library/administration building(Building One); z. Documenting the addition of the existing Building 1 to the Quarry Lane School campus. The building was acquired by the school in 1997 but the square footage was never reflected in the adopted Development Plan; 3. Documenting a potential future expansion area for Building One by 4,000 square feet for the purposes of creating a performing arts stage; and 4. Construction of retaining walls, site grading, and other related site improvements on the school site to accommodate the new building area, including the removal of seven trees (four eucalyptus, two redwood, and one Mexican fan palm). In order to accommodate the total 17,102 square feet of additional building area and associated site improvements, the following approvals are being sought: 1. Site Development Review for site and architectural approval of the 13,102 square foot cafeteria and science building; 2. Planned Development Rezoning/Development Plan Amendment to increase the allowable development on the project site from 85,889 square feet (as noted in the existing Development Plan)to 110,602 square feet. The added square footage is comprised of the following: Table 1: Project Description Square Status Description Feet Phase 1 15,60o Existing Allowed per Development Plan (2000) Phase 11 70,289 Existing Allowed per amended Development Plan (z000) Subtotal 85,889 Total allowed per Development Plan (2004) Existing building purchased by Quarry Lane and added to school Building 1 7,611 Existing campus Subtotal 7,611 Additional development existing on-site (2014) New Cafeteria/ Proposed Development Plan Amendment Science Building 13,102 Proposed and Site Development Review(SDR) Building 1:future 4,000 Proposed Proposed Development Plan Amendment-no SDR addition � Initial Study/Addendum for Quarry Lane School Phase III expansion project LAMM I A ATTACHMENT 5 Square Status 76_es cription Feet Subtotal 17,102 Total Additional Development proposed on site TOTAL lto,602 Proposed Development Plan Amendment The location of the new cafeteria/science building is shown in Figure 1 (Project Site Plan), which is attached. PRIOR CEQA ANALYSIS: The project site was previously reviewed for annexation and development as part of the Eastern Dublin EIR (SCH 91103604) prepared for the Eastern Dublin General Plan Amendment and Specific Plan project. The Quarry Lane School site was not annexed at this time and the property continued to remain in unincorporated Alameda County. The Eastern Dublin EIR was certified by the City Council on May io, 1993 via Resolution 51-93, incorporated herein by reference. Numerous mitigation measures were adopted, and continue to apply to the Quarry Lane School project and project site as appropriate. Significant unavoidable impacts were also identified; therefore, the City Council adopted a Statement of Overriding Considerations upon approval of the Eastern Dublin project (Resolution 53-93)• In April 1999, Alameda County approved the first phase of the Quarry Lane School, consisting of a 15,600- square -foot building for day care, preschool and elementary school grades with a maximum of zoo students. An Environmental Impact Report (Quarry Lane School, Environmental Impact Report, the 2o6o1n Zoning Unit, August 1998, SCH #97122109, incorporated herein by reference) was certified by the County prior to approving the Phase I project. The EIR included an analysis of the full build out of the school, consisting of 62,575 square feet of floor area for day care, preschool, elementary, middle and high school grades with a maximum of 950 students and 55 faculty and staff members. On December 19, 2000, the City of Dublin City Council approved a Planned Development District Pre-zoning and Annexation application for Phase 2 of the Quarry Lane School. The use, student population, building envelope, site layout, extent of grading, and construction were studied as part of the application. The total project size increased from the 62,575 square feet studied in the Alameda County Quarry Lane EIR to 82,263 square feet, but the student population did not change. An Initial Study and Mitigated Negative Declaration was prepared for the Phase 2 project that considered the following environmental factors: aesthetics; biological resources; public services; utilities/service systems; cultural resources; hydrology/water quality; noise; air quality; geology/soils; and transportation/circulation. The adopted Mitigated Negative Declaration determined that these impacts were less than significant with the mitigations incorporated into the project via City Council Resolution 204-0o, December 5, 2000, incorporated herein by reference. On May 25, 2004, the Planning Commission approved a Site Development Review application and minor amendments to the approved Stage 2 Development Plan that included a 3,604 square foot increase to the overall project building size (a total of 70,289 square feet), a minor amendment to the number of parking spaces (reduction to 149 total spaces required), and allowances for an additional retaining wall on site. With this amendment to Phase ll, an Addendum to the EIRs and Mitigated Negative Declaration was prepared that determined the changes to the Phase II project would not require major revisions to the previous EIRs or Mitigated Negative Declaration. The Addendum was approved by the Planning Commission via Resolution 04-46, incorporated herein by reference. Study/Addendum for Quarry Lane School Phase III expansion project CURRENT CEQA ANALYSIS AND _DETERMINATION THAT AN ADDENDUM IS APPROPRIATE_ FOR THIS PROJECT: In order to determine if there were any significant environmental impacts that were present with the Project that were not already addressed (and mitigated if necessary) in the previous environmental documents, an Initial Study was completed. The Initial Study, dated April 28, 2014 and incorporated herein by reference, determined that the potentially significant effects of the Project were adequately addressed in the Eastern Dublin EIR, the Alameda County Quarry Lane EIR, and the 2004 Quarry Lane School Phase II Mitigated Negative Declaration, and that no substantial changes have been proposed with the current Project or the conditions under which the Project will be undertaken which require revisions of the previous environmental documents. Based on the Initial Study, this Addendum has been prepared, which notes the difference in the Quarry Lane School Phase III project and the previous project approvals which CEQA impacts were addressed in the previously-certified EIRs and adopted MND. The Proposed Development Plan Amendment (Phase III expansion) compares to the Existing Development Plan (Phase II expansion and previous project approvals) as follows: Table z: Existing and Proposed Development Plans Approved Proposed Project Component Development Plan Development Plan Difference (Phase II: 2004) (Phase III: 2014) Student Population 950 950 None Faculty and Staff 55 55 None Classrooms 51 51 None Increase of 24,713 SF Total Building Area 85,889 SF 11o,602 (7,611 SF Existing Bldg.

Bldg. Height 59 feet 59 feet None The addition of 7,611 square feet in Building 1 to the Total Building Area is a result of the school's acquisition of the building and site, which existed on a separate parcel and served as a special events center ("Villa Tassajara") for many years. In 1997, Quarry Lane School acquired the site and parcel and incorporated the building into the school campus, utilizing the building for administrative purposes, library, and kitchen functions. This is not newly-constructed building area, but it is building area that had not been previously accounted for in the Quarry Lane School Development Plan, although it was referenced in the 2000 Initial Study and Mitigated Negative Declaration. 3T___ Initial Study/Addendum for Quarry Lane School Phase III expansion project Although the proposed project allows for a new 13,102 square foot building to be constructed on site and allows for a future expansion to Building One by up to 4,000 square feet to allow for the addition of a performing arts area within the building, those factors which could intensify the use at the site - including the total number of students enrolled at the school and the number of faculty/staff members - is not increasing. Therefore, even with the construction of a facility such as the new cafeteria and science building and the future potential for an addition to Building One, the same maximum number of students are going to be served at the school site by the same maximum number of faculty and staff members, so the overall intensity of activity at the site remains the same as before the Phase I II expansion. NO SUBSEQUENT REVIEW IS REQUIRED PER CEQA GUIDELINES SECTION 15162: Pursuant to Section 15162 of the California Environmental Quality Act (CEQA) Guidelines, no subsequent environmental analysis shall be prepared for the Quarry Lane School Phase III expansion project, as no substantial changes have been proposed with the Project or the conditions under which the Project will be undertaken which require revisions to the previous environmental documents. No new significant environmental impacts have been identified and no substantial increase in the severity of previously identified impacts has been discovered. Pursuant to CEQA Guidelines Section 15164, with minor technical amendments and clarifications as outlined in this Addendum, the previous environmental documents will continue to adequately address the significant environmental impacts of the Quarry Lane School Phase III expansion project. CONCLUSION: The City prepared an Initial Study in connection with the Project; based on the Initial Study, the City prepared an Addendum to the previous CEQA documents. As provided in Section 15164, the Addendum need not be circulated for public review, but shall be considered with the previous environmental documents before making a decision on the proposed project. The Initial Study is included below and the previous environmental documents are available for review in the Community Development Department at the City of Dublin, loo Civic Plaza, Dublin, California. E Initial StudyiAddendum for Quarry Lane School Phase III expansion project INITIAL STUDY This Initial Study has been prepared in accord with the provisions of the California Environmental Quality Act (CEQA) and CEQA Guidelines. It assesses the potential environmental impacts of implementing the proposed project described below and whether those impacts are adequately addressed in prior environmental reviews for the site. The Initial Study consists of a completed environmental checklist and a brief explanation of the environmental topics addressed in the checklist.

The adjacent property to the south is designated Medium Density Residential (6.1 to 14 units per acre) and is currently occupied by a single-family home, landscape contracting business, and landscape nursery. In April 1999, prior to the site being annexed to the City of Dublin, Alameda County approved a Planned Development District to allow the development of the first phase of the Quarry Lane School, consisting of a 15,600-square-foot building for day care, preschool and elementary school grades with a maximum enrollment of zoo students. A programmatic Environmental Impact Report was certified by the County at that time for the Quarry Lane School Master Plan. On December 19, 2000, the City Council approved the Planned Development (PD) District Pre-zoning and Annexation application for Quarry Lane School Phase II (City Council Ordinance 24-00 —Attachment 1). The application was for a substantial increase to the amount of development on site to allow an additional 66,685 square feet to construct a middle school and high school building, recreation areas, landscaping and grading. This would allow Quarry Lane to expand from zoo students (daycare, preschool, and elementary school) to a population of 950 students that would include middle school and high school ages as well. The school use, maximum student population, ultimate building envelope, site layout, extent of grading, and architectural plans were approved by the City at this time. On May 25, 2004, the Planning Commission approved Resolution 04-46 (Attachment 2), which included a minor amendment to the Stage 2 Development Plan and Site Development Review. The application requested Site Development Review to construct Phase II, which included construction of 70,289 square feet of new building area (an increase from the 66,685 square feet approved in z000) and associated sports fields and playground areas to serve the middle and high school facilities. The project also included other minor site revisions. While the building area increased, the total maximum student population remained at 950 students. Proposed Project The Phase III expansion of Quarry Lane School includes Site Development Review and amendments to the Development Plan for the existing Planned Development District (Ord. 24-00) to allow for 17,102 square feet of additional building area on the school site, consisting of one new building of 13,102 square feet, and the potential to add up to 4,000 square feet to existing Building One at some point in the future. The total building area would be 110,602 square feet, which would also include the square footage of Building 1 (7,611 square feet), which was an existing building on an adjacent lot that was purchased by the School in 1997 and made a part of the school campus. The current proposal is to increase the amount of development permitted on site from 85,889 square feet (per the 2004 Stage 2 Development Plan approval) to 110,602 square feet and to increase the allowable Floor to Area Ratio (FAR) from .209 to .253. Table 1 below describes the factors in the proposed increase.

Environmental Checklist Environmental Factors Potentially Affected by the Project The environmental factors checked below would be potentially affected by this project, involving as indicated by the checklist on the following pages. Aesthetics Agricultural Resources Air Quality Biological Resources Cultural Resources Geology/ Soils Hazards & Hazardous Hydrology/Water Land Use / Planning Materials Quality Mineral Resources Noise Population / Housing Public Services Recreation Transportation / Traffic Utilities / Service Mandatory Findings of Significance Systems Instructions ! . 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 (see Attachment A: Source List). 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). 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. >. 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 any effect 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 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. Earlier Analysis may be used where, pursuant to the tiering, Program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or negative declaration. Section 15o63(c)(3)(D). In this case, the checklist entry will be "No New Impact" and a discussion should identify the following on attached sheets: d Initial Study/Addendum for Quarry Lane School Phase III expansion project a. Earlier analysis used. Identify earlier analyses 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. f; Initial Study/Addendum for Quarry Lane School Phase I II expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant /No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): �. AESTHETICS. Would the project: a) Have a substantial adverse effect on a scenic vista? X b) Substantially damage scenic resources, including but not limited to trees, rock outcroppings, and X historic buildings within a state scenic highway? c) Substantially degrade the existing visual character X or quality of the site and its surroundings? d) Create a new source of substantial light or glare, which would adversely affect day or nighttime X views in the area? Discussion The school campus is currently occupied by 93,5oo square feet of educational buildings, parking areas, recreational fields, and other facilities appropriate to a school and therefore the visual character of the site has already been determined. The proposed new two-story building(13,302 square feet)will be located behind an existing two story building and will have limited visibility from Tassajara Road. The future expansion area to Building 1 will be aesthetically complementary to the existing campus and within the development standards already specific in the Stage 1/2 Development Plan. No more substantial light or glare impacts will be created as a result of the new building or the future expansion area. The Quarry Lane M N D (2000) contained several mitigation measures that will continue to apply to the project site, including: The Quarry Lane Phase III expansion project would not have any impacts on aesthetics/visual resources beyond those already analyzed in the previous environmental documents, and therefore no new impacts would result. z. AGRICULTURE RESOURCES AND FORESTRY 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 Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state's inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project: a) Convert Prime Farmland, Unique Farmland, or X Farmland of Statewide Importance (Farmland), as o Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): 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 use, or X a Williamson Act contract? c) Conflict with existing zoning for, or cause rezoning of forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public X Resources Code section 4526) or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? d) Result in loss of forest land or conversion of forest X land to non-forest uses? e) Involve other changes in the existing environment, which due to their location or nature, could result in X conversion of Farmland to non-agricultural use or conversion of forest land to non-forest use? Discussion The project area has already been developed and there are no agricultural or forestry present, no agricultural zoning or Williamson Act land, and therefore there would be no new impact. 3. AIR QUALITY. Where available,the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the X applicable air quality plan? b) Violate any air quality standard or contribute to an X existing or projected air quality violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state X ambient air quality standard (including releasing emissions, which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant X concentrations? e) Create objectionable odors affecting a substantial X si Initial Study�Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): number of people? Discussion The proposed}project does not increase the maximum student population able to be accommodated on site nor does it allow for an increase in the number of faculty and staff at the school. Therefore, the vehicular trips to and from the school site will not increase beyond that which was previously assumed and the air quality impacts normally attributed to vehicular emissions would not be increased. Since the maximum student population is not increasing, the number of potentially sensitive receptors is not increasing either. The school campus will not create objectionable odors. The Quarry Lane Phase III expansion project would not have any impacts on air quality beyond those already analyzed in the previous environmental documents, and therefore no new impacts would result. 4. BIOLOGICAL RESOURCES. Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status X 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 riparian habitat or other sensitive natural community identified in local or regional plans, policies, X regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, X marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory X wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local policies or ordinances protecting biological resources, such as a tree X preservation policy or ordinance? Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community X Conservation Plan, or other approved local, regional, or state habitat conservation plan? Discussion The school campus is currently occupied by 93,5oo square feet of educational buildings, parking areas, recreational fields, and other facilities appropriate to a school. The location of the proposed new cafeteria and science building is currently occupied by a storage shed, outdoor eating area for students, and a commercial grade walk-in refrigerator. Therefore, there are no biological resources present on the project site near the proposed expansion areas. There are seven trees that are proposed to be removed from the project site, including four eucalyptus, two redwoods (with trunk diameters of io inches and 12 inches) and one Mexican fan palm tree. These trees are located in areas that are to receive extensive grading. All other landscaping is to remain on site, and the newly-created slope areas are to be planted with groundcover. The Quarry Lane Phase III expansion project would not have any impacts on biological resources beyond those already analyzed in the previous environmental documents, and therefore no new impacts would result. 5. CULTURAL RESOURCES. Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined in X CEQA Guidelines section 15o64.5? b) Cause a substantial adverse change in the significance of an archaeological resource pursuant x to section 15o64.5? c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic X feature? d) Disturb any human remains, including those X interred outside of formal cemeteries? Discussion The school campus is currently occupied by 93,5oo square feet of educational buildings, parking areas, recreational fields, and other facilities appropriate to a school. The location of the proposed new cafeteria and science building is currently occupied by a storage shed, outdoor eating area for students, and a commercial grade walk-in refrigerator. No historic resources exist on site. While the likelihood of finding archaeological and/or cultural resources on the project site in the 13 Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): location of the future buildings is low, in the event that such resources are encountered, mitigation Measure 3.9/5•o and 6.o contained in the Eastern Dublin Specific Plan EIR establishes procedures to be activated in the event archeological resources are encountered during grading. The Quarry Lane Phase I I I expansion project would not have any impacts on cultural resources beyond those already analyzed in the previous environmental documents, and therefore no new impacts would result. 6. GEOLOGY AND SOILS. Would the project expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: a) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the X area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42? b) Strong seismic ground shaking? X c) Seismic-related ground failure, including X liquefaction? d) Landslides? X e) Result in substantial soil erosion or the loss of X topsoil? f) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site X landslide, lateral spreading, subsidence, liquefaction or collapse? g) Be located on expansive soil, as defined in Table 18- 1-B of the Uniform Building Code (1994), creating X substantial risks to life or property? h) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater X disposal systems where sewers are not available for the disposal of wastewater. Discussion Since the site is not located within an Alquist-Priolo Earthquake Safety Zone, the potential for ground rupture is anticipated to be minimal. Adherence to Mitigation Measures MM 3.6/i.o through 8.o contained in the Eastern Dublin EIR will ensure that new structures built on the site will comply with generally recognized seismic safety standards so that ground shaking impacts would be � Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant /No New ENVIRONMENTAL IMPACTS Issues Incorpor.

The previous environmental documents include a number of mitigation measures to deal with geologic impacts, including the requirement for a soils report prior to issuance of building permits, completion of a geotechnical report for the site, identifying appropriate construction methods and techniques consistent with generally recognized engineering principles; Review of the final grading plan by a geotechnical engineer; and Identification of specific methods to minimize risk of landslides and expansive soils as part of the geotechnical report. Construction of any future buildings on the project site will need to comply with these requirements. The Quarry Lane Phase III expansion project would not have any impacts on geology and soils beyond those already analyzed in the previous environmental documents, and therefore no new impacts would result. 7. GREENHOUSE GAS EMISSIONS. Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on X the environment? b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions X of greenhouse gases? Discussion Impacts related to Greenhouse Gas Emissions were not analyzed in any of the prior environmental documents. However, the proposed project does not increase the maximum student population able to be accommodated on site nor does it allow for an increase in the number of faculty and staff at the school. Therefore, the vehicular trips to and from the school site will not increase and the vehicular emissions generated will not increase. 8. HAZARDS AND HAZARDOUS MATERIALS. Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or X disposal of hazardous materials? b) Create a significant hazard to the public or the environment through reasonably foreseeable upset X and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste X within X mile of an existing or proposed school? d Be located on a site which is included on a list of X 15 Initial Study/Addendum for Quarry Lane School Phase III expansion project I Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? (V.13) e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, X would the project result in a safety hazard for people residing or working in the project area? f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for X people residing or working in the project area? g) Impair implementation of or physically interfere with an adopted emergency response plan or X emergency evacuation plan? h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized X areas or where residences are intermixed with wildlands? Discussion The new science building will contain small amounts of chemicals for the purposes of middle and high school level appropriate science experiments. The amount of chemicals allowed to be stored on site is regulated by the Fire Prevention Division of the City of Dublin. There is no potential impact from the limited nature and use of these chemicals. The project area is not located within an airport land use planning area nor near a private airstrip. It will not create a hazard for the public, impair the execution of any emergency response plans, nor will it increase the risk of wildland fires. Therefore, there is no potential impact from the Project. The Quarry Lane Phase I I I expansion project would not have any impacts on hazards and hazardous materials . 9. HYDROLOGY AND WATER QUALITY. Would the project: a) Violate any water quality standards or waste X discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge X such that there would be a net deficit in aquifer volume or a lowering of the local ground water :� ( Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts issues(and Supporting Information Sources): table level (for example, the production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner, which X would result in substantial erosion or siltation on-or off-site. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially X increase the rate or amount of surface runoff in a manner, which would result in flooding on-or off- site. e) Create or contribute runoff water which would exceed the capacity of existing or planned storm X water drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially degrade water quality? X g) Place housing within a loo-year flood-hazard area as mapped on a federal Flood Hazard Boundary or X Flood Insurance Rate Map or other flood hazard delineation map? h) Place within a loo-year flood-hazard area structures, X which would impede or redirect flood flows? i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including X flooding as a result of the failure of a levee or dam? j) Inundation by seiche, tsunami, or mudflow? X Discussion The school campus is currently occupied by 93,5oo square feet of educational buildings, parking areas, recreational fields, and other facilities appropriate to a school and therefore is considered a developed site. All future construction will need to comply with the requirements of the Regional Water Quality Control Board as well as all City of Dublin stormwater treatment and water quality requirements. No new impacts to hydrology and water quality will result from the implementation of the project that have not already been addressed in previous environmental documents. �� Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): io. LAND USE AND PLANNING. Would the project: a) Physically divide an established community? X b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general X 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 Conservation X Plan or Natural Community Conservation Plan? Discussion The proposed project is in conformance with the General Plan and Eastern Dublin Specific Plan. There is no adopted Habitat Conservation-or{Natural Community C-onservation Plan for the site. No new impacts to land use and planning will result from the implementation of the project that have not already been addressed in previous environmental documents. ii. MINERAL RESOURCES. Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and X the residents of the state? b) Result in the loss of availability of a locally important mineral resource recovery site delineated X on a local general plan, specific plan, or other land use plan? Discussion There are no known mineral resources within the City of Dublin or designated in the General Plan or other land use plan, and therefore there would be no impact. 12. NOISE. Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local X general plan or noise ordinance or applicable standards of other agencies? b) Exposure of persons to or generation of excessive ground borne vibration or ground borne noise X levels? c) Substantial permanent increase in ambient noise X levels in the project vicinity above levels existing � � Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): without the project? d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above X levels existing without the project? e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, X 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 airstrip, would the project expose people residing or working in the project area to excessive noise X levels? Discussion The expansion of the school campus will not result in new noise impacts because the maximum student population is remaining the same, and therefore no new noise sources will be created on site. Temporary noise impacts due to construction on site have been analyzed and mitigated in the existing environmental documents and related mitigations will apply to the Project. No new impacts to noise will result from the implementation of the project that have not already been addressed in previous environmental documents. 13. POPULATION AND HOUSING. Would the project: a) Induce substantial population growth in an area, either directly (for example, by proposing new X homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing housing, necessitating the construction of replacement X housing elsewhere? c) Displace substantial numbers of people, necessitating the construction of replacement X housing elsewhere? Discussion The proposed project will not add new population to the area nor will it displace any housing, therefore no new impacts will result. 14. PUBLIC SERVICES. Would the project result in substantial adverse physical impacts associated 3g Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): with the provision of new or physically altered governmental facilities or need for new or physical altered governmental facilities,the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services: a) Fire protection? X b) Police protection? X c) Schools? X d) Parks? X e) Other public facilities? X Discussion New construction projects are required to comply with applicable building, safety, and fire codes, fund on- and off-site improvements, and contribute to the City's public facilities fees commensurate with the type, size and scope of the project. There will be no new impacts resulting from the proposed project that are different than those analyzed in the previous environmental documents. 15. RECREATION. Would the project: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such X that substantial physical deterioration of the facility would occur or be accelerated? b) Include recreational facilities or require the construction or expansion of recreational facilities X which might have an adverse physical effect on the environment? Discussion The proposed project will not result in the increased use of existing public recreation facilities, nor cause the need for new facilities, therefore no new impacts will result. 16. TRANSPORTATION/TRAFFIC. Would the project: a) Conflict with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant X components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or X other standards established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in X location that result in substantial safety risks? d) Substantially increase hazards due to a design feature (for example, sharp curves or dangerous X intersections) or incompatible uses (for example, farm equipment)? e) Result in inadequate emergency access? X f) Conflict with adopted policies, plans, or programs supporting regarding public transit, bicycle, or X pedestrian facilities, or otherwise decrease the performance or safety of such facilities? Discussion The proposed project does not change the emergency access routes to the site, change any circulation features of the project site, or impact any transportation facilities serving the area. The proposed project does not increase the maximum student population able to be accommodated on site nor does it allow for an increase in the number of faculty and staff at the school. Therefore, the vehicular trips to and from the school site will not increase beyond that which was previously assumed and therefore no new impacts to transportation would result. 16. UTILITIES AND SERVICE SYSTEMS. Would the project: a) Exceed wastewater treatment requirements of the X applicable Regional Water Quality Control Board? b) Require or result in the construction of new water or wastewater treatment facilities or expansion of X existing facilities, the construction or which could cause significant environmental effects? c) Require or result in the construction of new storm water drainage facilities or expansion of existing X facilities, the construction of which could cause significant environmental effects d) Have sufficient water supplies available to serve the X z: Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant /No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the X project projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste X disposal needs? g) Comply with federal, state, and local statutes and X regulations related to solid waste? Discussion No new or expanded utility systems would be required and there would be adequate capacity with existing infrastructure. Additionally, new construction is required to contribute to the City's impact fees to fund public service infrastructure commensurate with the type, size, and scope of the new construction. The Dublin San Ramon Services District (water and sewer provider) has provided its standard conditions of approval for the proposed project . No new impacts to utilities and service systems will result from implementation of the proposed project. 17. MANDATORY FINDINGS OF SIGNIFICANCE. Does the project: a) Have the potential to 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, X 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) Have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in X connection with the effects of the past projects, the effects of other current projects, and the effects of probable future projects.) c) Have environmental effects, which will cause X substantial adverse effects on human beings, either Initial Study/Addendum for Quarry Lane School Phase III expansion project Potentially Significant Potentially Unless Less Than No Impact Significant Mitigation Significant No New ENVIRONMENTAL IMPACTS Issues Incorpor. Impact Impacts Issues(and Supporting Information Sources): directly or indirectly? Discussion (a-b) The project area is a developed site. The project area contains buildings, parking lots, and recreational facilities, and there is no natural habitat for fish or wildlife species. Because the site is already developed, there would be no new impacts to sensitive plant and animal species, riparian habitat, and federally protected wetlands, and/or archaeological resources. Future development within the project area will not have the potential to degrade the quality of the environment, substantially reduce habitat or eliminate habitat for fish and wildlife species below self-sustaining levels, and/or eliminate important examples of California history or pre-history. (c) As described throughout this environmental checklist, the proposed project would not result in substantial environmental effects on human beings either directly or indirectly and therefore there would be no new impacts. z3 Initial Study/Addendum for Quarry Lane School Phase III expansion project 1� I ♦.Y9' ♦A♦ fff ��A�. ►�ei� �.
