Schedule the second reading of the Ordinance for the December 19, 2000 City Council meeting. BACKGROUND: On November 21, 2000, the City Council opened the Public Hearing on the Quarry Lane School, Planned Development Prezone and Annexation project and continued the item to the December 5, 2000 meeting at the request of the Applicant. PROJECT DESCRIPTION AND ANALYSIS: Please refer to Attachment 1, City Council staff report, dated November 21, 2000 which discusses the proposed prezoning and annexation request for the Quarry Lane School and Kobold properties. ENROLLMENT AND PARKING STUDY: A study of all Dublin schools was conducted to determine the number of students' enrolled and on-site parking spaces available. Please refer to Attachment 2 Dublin Schools (Private & Public) Enrollment and Parking Study, November 2000. The Dublin Zoning Ordinance requires private schools to provide parking based on the number of students and classrooms in the school. Elementary, Middle and Junior High requires two parking spaces per cIassroom and High schools require one parking space per cIassroom and one parking space per every four students. 2 Phase 1 of Quarry Lane School (elementary grades) consists of 14 classrooms and 200 students. Phase 2 proposes the addition of 42 Middle school classrooms and 600 students and 10 High School classrooms and 150 students. Based on the Dublin Zoning Ordinance requirements, 160 on site parking spaces are required. The traffic study prepared by Charles Abrams and Associates for this project, also analyzed parking requirements and determined that 145 parking spaces would be adequate to accommodate staff, student and visitor parking demand. The proposed site plan indicates that 166 stalls will be provided on- site. Quarry Lane School (Phase 1 and 2) would provide 5.7 parking spaces per student. Valley Christian is the only other existing private school in the City that provides elementary through high school grades. Parking at Valley Christian is provided at a ratio of 2.3 stalls per student. The parking to be provided at Quarry lane School is comparable to that provided by Dublin High which provides 5.1 stalls per student. Whereas, the public schools and Valley Christian have on-street parking nearby, no on-street parking is available in the vicinity of the Quarry Lane School. DEVELOPMENT PLAN: A Development Plan has been prepared to establish regulations for the use and development of the Quarry Lane School site. The Development Plan is attached as Exhibit A-2 to the City Council Staff Report dated November 21,2000. The Development Plan has been revised to incIude special events such a~ 'back to school nights', school festivals, graduation ceremonies et~. as temporary uses. Prior to conducting any special event, the school would be required to obtain a temporary use permit from the Community Development Department, so that the City could assure that adequate parking arrangements would be made for the event. Refer to Attachment 4 of this Staff Report, the changes are shown in italics. RECOMMENDATION: Staff recommends the City Council, deliberate and I. Adopt the following resolutions: . Attachment 1 (of Staff Report dated 11/21/00) City Council Resolution adopting a Mitigated Negative Declaration, Mitigation Monitoring Program and the Response to Comments . Attachment 3 (of Staff Report dated 11/21/00) City Council Resolution authorizing an application for reorganization to Alameda County Local Agency Formation Commission (LAFCo) with annexation description and maps attached as Exhibits B-1, B-2, B-3 and B-4 and the Plan for Services attached as Exhibit B-5 .

PROJECT DESCRIPTION: The project sity i~ lQcatednorth of the e{(i~ting citylitrijt~,()n th~ east side of Tassajara Road, approximately 2 miles north ofI-580 within unincorporated AIW1~da County. The site contaihs tWo prop~rtiy~, t4~ Q1.l,apy Lan~ School and the K()boI4property, located at 6363 and 6237 Tassajara Road respectiy~ly, Thy KoboI4 property is l()caty4 aqjl;lcent to the. city limits, south of the Quarry Lane ,School site. The total site includes approximately 13.7 acres of land. The Applicant, Dr. Arac of Quarry Lane School is requesting approval to allow the development of Phase 2 of the privately owned school at 6363 Tassajara Road. Phas~ 2 of Quarry Lane School would incIude the construction of66, 685 square feet of classroom and adrniJ:1istrative space to house 750 students and 55 staff and recreational play fields. Construction ofPhasy 2 would increase the need for public services and facilities beyond that available from existing private facilities. Therefore, annexation to the City of Dublin and DublinSan RW1()ll Services District is requested to obtain th~ n~c~~sl;lfy level and range of urban services to facilitat~ future expansion of the school. The State reorganization act. (Knox .;.Cortese) requires that propertiyS proposed for annexation be contiguous with the boundaries of the jurisdiction to which annexation is proposed. Therefore, the KoboId prQperty is proposed to be inclu4~ii in.t4e. anpexation action, since it is the intervening propyrty betweyll thy city limits and the Quarry Lane School site. H()wever, no development is proposed for the Kobold property at this time. The proposed project includes the following entitlements: . Planned Development Prezoning and Stage. 1 and 2 Development for Phase 2 of the Quarry Lane School .

Proposal to Revise.JJevelopmeniPlan: In response to COmIllents from Mr. Nielsen, the property owner to the irn:rnediate north of the Quarry Lane . School site, the applicant, Dr. Arac proposed to revise the rear portion of the school. The revision iIivolved lowering the elevation of the play field and moving the play field approximately tWenty feet to the. south (:Kobold property). It was anticipated that moving the phiy. :field would reduce the noise levels generated by olitdootschool activities at the Nielsen residence; Relocatmgthe play field requ.ued the addition of new retaining walls along the north side of the play field. and the redesign of the access between the Phase. 2 buildirtgand the play field. The changes to the site plan reduced, and in some cases eliminated, the 'run-off area between the edge of the play field and the retaining wall, thereby creating a hazard for sports players. The revised site plan presents an awkward transition from the thirdt100r of the building to the play field for student access. Relocatmgthe play field closer to Kobold' sproperty may result hi additiOnal noise and other impacts to that property. . Also, the revised site plan would require additional cllttiIig of the hillside and the removal of more earth off-site. 5 . . ... .. 6 ~ ;?

Consistency with Gen~ral Plan andEastern Dublin Spe-cific Plan: The Eastern DllbliU Specific PlM Specific / General Plan designateS the propertY f.or MediUlli Density residential and Rural Residential/Agricultural uses, Aschoolllse.Withinthis designation is a,ppropriate because the Eastern })ublinSpecific Plan envisions this area (iclentifled as subarea G: Fo.othill residen.tial in the SPecific Plan,) to be developed WithPr<::dornihantly residenthil aricl .open space uses, as well as uses irtclu(iil1gpllblicscl1oolsand,Patks.

ENVffiONMENTAL REVIEW The project is within the Dublin General Plan~ s Eastern Extended Planning Area and the Eastern Dublin Specific Plan Area, whiCh was the subjectofl:Ul Elivironmental Impact Report, certified by the City of Dublin in 1993., .The General PlanJSpecific Plan EIR ~s.a program EIR, which analyzed the ,enviroiUnelltal issues related to 'tP:@ land 1.ise locations, development plans arid policies contained in the Eastern Dublin Specific. Plan. The EIR also anticipated several subsequent actions related to future development in Eastern Dublin. . The EIR did identify some imp~cts from implementation of the General Plan/Specific :pla.fi that W@l,'e not able to be mitigat@d. Upon certificatiollof the ErR, the City adopted a Statement ofDverriding CohSiderat~ons for several. impacts, some of which relate to. this projecL The City also adopt~d a ll1i~g&~0111l1.9nitoringprogratJ;1.,whichiricluqed ineasures intencied t611educeunpacts. from the developItlentofEastetn Dublin area. These mitigation measures apply toproj@ct approvals and actions at various stages in the development proc@ss, a.nd will be aPPlied to this project as applicable. The tUning of these mitigation measures is indicated in the City~ s EIR mitigation monitoring matrix (City Council Resolution # 53-93) incorporated herein by reference. An Environmental Impact Report for Quarty Lane School was certified by Alameda County Board of Supervisors in 1999. Th~ EIR anaIyzedenviromnental issues relating. to the proposed school in the areas ofland use, visual quality, geology, hydrology, traffic and circulation, air qua1ity~ noise, public services 7 and utilities. Upon certification of the EIR, the Eoard of Supervisors adopted a Statement ofQve:rri~1 Considerations for impacts relating to high noise levels as a result of construction activity and adopted a mitigation monitoring program. ~3J An Initial Study was prepared for the 'proposed ptoj ect, involving an annexation and prezol1ing request for 6363 and 6237 Tassajara Road. The Initial Study utilized technical inforrriation and analysis in both the Eastern Dublin EIR and the County EIR to determineif additional impacts would docmas a result of this proposal. The Initial Study determined that with the implementation of Mitigation Measures previously adopt~dforthe E~stern.Dublin EIRand.with site speciflcc.MitigationMeasures contained in the Initial... . . Study, the potential site-"specific impacts of the project would be reduced to a level of insignificance and the proposed proj~ct Will n9t have asiglliflcatlt effect on theenvrronn:ieht. The pUblic review period of the Ihitial StudylMitigated Negative Declaration was held from July 19, 2000. thrOUgh August 7, 2000. A copy of the IhitiaI Study/Mitigated Negative DecIaration is ihcIuded as Attachnient6. During the Public Comment period four cofu:tiient letters Were received from Mr. Kyle, Attorney representing Mr. Nielseri (the property owner to the immediate north of the project site), local and State agericies, ihcludihg the Regional Water Quality Control Board, East Bay Regional Park District and Alameda County Flood Control and . Water COllservation District; Zone 7 . Staffhas prepared responses to each of these lettets. Thecomtnent letters and responses are attaChed as AttliChmeni 7 to this staff report. The letter received from Mr. Kyle focused on two issues, the potentialgtading 'and noise im.pacts that coUld result from thedeveloptnent of the proposed. Phase 2 site plan for Quarry lane School. Mr. Kyle req\lests that a new EIRshould be prepared to address theenvirohmental impacts of this site plan. The agencies cofu:tiientsprimarilYl'elatedto issues of storm.water runoff and water quality. In addition; the East Bay Regional Park District comments related to impacts that may occur as a result of heavy use of the park by future students of the schooL The District requests theopportuniWto meet with the School to discllSs these issues. The City's response to each of these comfilent letters is attached as Attachment 7 to this staffreport; The folloWing is a brief discussion of the pertihent issues: Traffic issues: A traffic study was conducted for the Quarry Lane School by Abrams Associates, Transportation Consultants. Traffic impacts were not analyzed for the KoboId property as no development is proposed at this time. The study concluded that with the construction of a traffic signal at the school entrance, there would be no. sigriificant traffic impacts as a result of this project. Theprogram EIRdetermined that the development of Easte:ro Dublin woUld result in several traffic impacts, however these impacts would be mitigated by transportation improvements funded through the payment of traffic fees by new dev:elopmentwithih the eastern Dublin area. The Applicaritwill be required to pay traffic fees as part of this. development. VisualandGradin~: The proj ~ct was evaluated to determ.ine whether the proj ect design complies with the mitigation measures of the Eastern DublinEIR and the Eastern Dublin Scenic Corridorpolides. A number of these policies have been reflected mthe project design to minimize visual itnpacts, site grading, the nlimber and height 6fretaining walls and to design the bllildihg tofitth~ existing topography. With the adherence to mitigation measures of the Eastern Dublin EIR and site...specific measures identified in the Initial Study, no significant itnpacts were identified for the project. Noise: The County EIR for the Quarry Lane School analyzed the potential noise impacts of the project and determ.ined that minimal noise impacts would be caused by vehicular traffic or school activities. Noise related to school activities would primarily involve children using the recreational play fields towards the center arid rear of the site; . Surrounding uses woUld largely be shielded by the new buildings and topograPhy and noise levels woUld only occur during the school day. An updated noise study has 8 been prepared by Wilson Ihrig and Associates (refer to Attachment A of Attachment 9~ Respop.se. tp <J d 0:< 8_ Co1111i:l,ents) to evaluate potential p-oi$e impacts a.s a result of the revi$ecl Pha,se 4. site pl~.

R AGENCYIDEPARTMENT REvIE..W , - ".' "". " -..',.... ., "'- ',,' . ' .' . ' -.. The proposed project has been reviewed by the BuilclingDepartment, the Public Works Pepartment, Police Services and Alameda County Fire Department. The concerns raised are reflected in the design of the project ~cll or in the miti.gatiQl11J:lea,sure.s identified in the Initial StudyIMitigated Negative Declaration prepared for theptoject PRE-ANNEXATION AGREEl\'.tJjJNT The goals and policies of the Eastern Dublin Specific Plan require annexatiOll aJ1dnew develppment to be revenue neutral. It is estimated that the cost of providing public services to the Eastern bublin Area (includiP-!54he ~exation area) could ex<;eed revenues oyer the next several years. If new development occurs witHin Eastern Dublin as anticipated, it is expected to generate revenues to the City which will exceed costs over the long-term as predicted in the Eastern Dublin Specific Plan. The City will require the developer of the Quarry Lane School to enter into an agreement (Refer to Exhibit C to Attachment 5) to pay, the school's proportionate share of the public services deficit and certain major road improvements. Theagreement will assure that the financing goals and policies of the Specific Plan are met. DUBLIN UNIFIED SCHOOL DISTRICT The Dublin General Plan policies state that "schools located within the city should be operated by the Dublin Unified School District". It is the intent of the City that the boundaries of the Dublin School District should be coterminous with the City limits. The project site is currently located within the Livermore Valley Joint Unified School District. The detachment of the project site (Quarry Lane School and Kobold properties) from the Livermore School District and annexation to the Dublin School District is not subject to LAFCo approval. The Planned Development Prezone contains a provision which requires that the applicant cooperate and actively worKwith other property owners within the City of Dublin's sphere of Influence to initiate and complete the annexation process to the Dublin Unified School . ~~ . CONCLUSIONS The proposed Planned Development Prezone and Annexation request for the Quarry Lane School and Koboldproperties is consistent with the Dublin General Plan, Eastern Dublin Specific Plan and Dublin Zoning Ordinance. The ptoject will accommodate the logical extension of public services within Eastern Dublin and will provide for futurelancl uses anticipated in the Eastern Dublin Specific Plan. -'\ 9 RECoMMENDAnON: Staff reco1lll11eIids the City CounCil open the Public.

The Planned Development Prezone will provide efficient use ofland and will preserve an area of open space and undisturbed hillside along the north and primarily the northeast corner of the property; and will be compatible with and enhance the general development ofthe area; and will create an attractive, efficient and safe environment and physically suitable for the type and intensity of the zoning and uses proposed; and 6. The Planned Development Prezone will not have a s.ubstantial adverse effect on health or 2 lib q{ do3.J safety or be substantially detrimental to the public welfare or be injurious, to property or public improvement, as all applicable regulations will be met; and 7. The Planned Development Prezone will not overburden public services or facilities as all agencies must commit to the availability of Public Services prior to the issuance of any building permits as required by the Eastern Dublin Specific Plan policies and Mitigation Measures; and 8. The Planned Development Prezone will be consistent with the policies of the Dublin. General Plan and the Eastern Du,blin Specific Plan; and 9. The Planned Development Prezone will benefit the public necessity, convenience and general welfare; and 10.. The adopted Eastern Dublin Specific Plan Mitigation Monitoring Program and the addition!=ll site specific mitigation measures identified. in the Initial Study (Attachment 6 to Staff,~eport) will apply to the Project, as the reporting and Inonitoring program required by Public Resources Code 21081.6 for the Project WHEREAS, pursuant to Section 8.32.070 and 8.12Q.050 and 8.120.110 of the Dublin Municipal Code, the City Council makes the following fin.dings regarding said. prop()sed Planned DeveloPInent Prezone for the Kobold property: 1.

Transit LA VT A- Wheels BART LAVTA-Wheels BART EXHffiIT B-S '/c) 0-6 ~ j~ PLAN FOR MUNICIP ALSERVICES QUARRY LANE SCHOOL REORGANIZATION INTRODUCTION Since the incorporation of the City of Dublin in 1982, development in Eastern Dublin was envisioned as someday being a part of the City. It is identified as the Eastern Extended Planning Area in Dublin's original General Plan (1985). In 1994, the City adopted the Eastern Dublin Specific Plan, for the purpose of directing long-term land use, circulation, infrastructure and environmental protection for 3,302 acres ofland within Eastern Dublin. At full build-out, the planning area would allow a range of residential, commercial office, employment and open space uses. At the time the Eastern Dublin Specific Plan was adopted approximately 20% of the land area was located within the City of Dublin. In 1995, Alameda County Local Agency Formation Commission (LAFCo) approved the annexation of 1,500 acres of land within the Specific Plan to the City of Dublin and Dublin San Ramon Services District (DSRSD). To date, approximately 72% of the Specific Plan area is currently within the City of Dublin and approximately 63% of the. plan area has been developed, is currently under construction or has been approved for future development or permanent open space. The proposed reorganization involves approximately 15.07 acres of land located on the east side of Tassajara Road, approximately 2 miles north of Interstate 580 within unincorporated Alameda County. The annexation area is within the City of Dublin and Dublin San Ramon Service District's spheres of influence and within the Eastern Dublin Specific Plan area. The reorganization would incIud€ annexation of the site to the City of Dublin and annexation to Dublin San Ramon Services District. The annexation area contains a portion of Tassajara Road and two properties, the Quarry Lane School and the Kobold property located at 6363 and 6237 Tassajara Road. Description of Proposed Annexation: The annexation area is currently developed and consists of three parcels of record and a portion of Tassajara Road. Existing uses include Phase I of the Quarry Lane School which opened for the 2000/01 school year in mid-September. Phase 1 contains the existing Villa Tassajara building that has been incorporated into the school as the administrative building and 13 classrooms in a new 15, 600 structure to accommodate 200 pre-school through elementary grade students. A single-family residence, landscape contracting business and plant nursery exists on the Kobold property. A tributary of Tassajara Creek forms the southern boundary of the Kobold property. Phase I of Quarry Lane School and the Kobold property is currently served by private well and septic facilities. The proposed annexation has been requested by Quarry Lane School, which intends to construct Phase 2 of the school to include an additional 66, 685 square feet of classrooms, administrative space and a gymnasium to accommodate additional 750 middle through high school students and recreational play fields. At full build~out, the school would house 950 students and 55 faculty and staff. Construction of Phase 2 would increase the need for public services and facilities beyond that available from existing private facilities. Therefore annexation to the City of Dublin and Dublin San Ramon Services 2 '-/ / ~ 013'; District has been requesteAtOipbt::j.in th~.nec~s1:lary level and range of urban services to facilitate future ex;pansion of thy.,school~ Availability afServices: .

This task is required by mitigation measures of the EIR and accomplished through completi~n of the report entitled "Eastern Dub~n Faciliti~s Plan Final ReI'ort" (G.S. Dod~()na,nd Ass~ciate~< D~cember,1993) and mpre recentIYby.th~ "Urba,nWater Mana!5.ement Plan" ( DS:RBD~. May, 20'00 and the '''Plan for S~rvices for the Quarry Lane School annexat.ion", DSRSD,October 2000. An Initial Studyand Mitigated Negative Qeclaration wa$ prepared for the proposed annex~tion to evaluate the site..sp~cificimpacts ofth~ project to a greater. level of d~taiI them in the program EIR. The Eastern Dublin Specific Plan and program EIR in 3 t/)., ~ ~33 conjunction with the Mitigated Negative Declaration represent, in effect, a "Plan for Services" for project site. WATER DSRSD has been actively planning to provide water service to Eastern Dublin for many years. The Eastern Dublin Specific Plan was prepared in conjunction with DSRSD and includes policies and programs for water supply, wastewater and storm drainage for Eastern Dublin. To update information contained in the Specific Plan and provide a basis for future infrastructure planning efforts throughout the Eastern Dublin area, DSRSD . prepared the 'Eastern Dublin Facilities Plan, Final Report (G.S. Dodson and Associates; December, 1993). DSRSD has prepared an "Urban Water Management Plan" (UWMA), dated 1996 and updated May, 2000 to ensure that adequate water would be available to supply existing and future demand to the Dublin area, including the annexation area. More specifically, DSRSD has prepared a 'Plan for Providing Services, Potable Water, Wastewater Collection, Treatment and Disposal for the Quarry Lane School/Kobold Annexation', dated October 2000 (refer to Attachment A). Infrastructure will be.extended from Tassajara Road to the annexation area by Quarry Lane School and DSRSD will provide water services to the annexation area. WASTEWATER Wastewater services for the annexation area will be provided by. DSRSD. The District has been actively planning to provide wastewater collection, treatment and disposal services to the east Dublin area since 1993. DSRSD has prepared a plan for providing wastewater services for the annexation area and is attached as Attachment A ('Plan for Providing Services, Potable Water, Wastewater Collection, Treatment and Disposal for the Quarry Lane SchooVKobold Annexation', DSRSD, dated October 2000) STORM DRAINAGE Zone 7 of the Alameda County Flood Control and Water Conservation District is the. responsible agency for major drainage and flood control channels within Eastern Dublin, including the tributary of Tassajara Creek which forms part of the southern boundary of the annexation area. Upon annexation, the City of Dublin will be responsible for local storm drains which connect to this Zone 7 channel. POLICE PROTECTION Currently police protection for the annexation area is provided by the Alameda County Sheriff's Department and the California Highway Patrol. Once the area is annexed, police responsibilities will be provided by the Dublin Police Department. The Dublin Police Department is a division of the Alameda County Sheriff's Department and is funded by the City through a contractual agreement with the County. Dublin owns the department's facilities and equipment but the personnel are employed by the County Sheriff's Department. The City's police department is a full service operation except for dispatch which is provided through the County Sheriff's dispatch office in San Leandro. The Dublin Police Department currently has 40 sworn officers and 6.5 civilian staff and operates out of a central facility in the Dublin Civic Center. 4 713 e6 ,;;,33 As development in E~stemDublin is.q<.impleted and occupi~d, adciitional officer$and services are planned to serve the east Dublin residents. Accordingto the City's police department, the level of existing and planned officers and services are adequate to serve the proposed annexation area. When Phase 2 of Quarry Lane School is operational, an additional Crime Prevention Officer providing drug awareness and other student cIasses may be reqUired. If necessary thi$ position will be funded by the CitY. FIRE PROTECTION At theplJesent time, fire protection services to the anne~ationarea are provided by the Alameda County Fire Departmentand the California Division o(Forestry. Currently the City's fire prQt~ctionservices~reprovided by the Dublin Division of Alameda County Fire Department (ACFD)and funded by the City through a contractual agreement with the County. Withanne~ation,theDublin Division of Alal11eda County,Eire Department would becoI11e responsible for fire services. Under the terms of the agreement, all Alameda County fire protectionpersonnel and services would be availabl.e to respond in the event of an emergency within the City limits. There are two fire stations within the City of Dublin, fire station sixteen located at Donohue Drive and fire station fifteen located within the Santa Rita, Jail cOmplex!lolih of Gleason Drive. ACFD operates under a standard of a 1.5 mile response zone for each station in order to maintain a response time within 5 minutes. Future development within Eastern Dublin requires the construction' of two new,stations in order to maintain th.ese standard response times. The new. stations would be located at Madigan Road, north of Gleason Drive and. east of Fallon. Ros,d and would be operational by20Q$ and 2004, respectively. Accordingto ACFD, sufficient fITe,protection personnel, facilities and equipment currently existto serve the proposed annexation area. SOLID WASTE Coordination of solid waste management activities in Alameda County.is a joint responsibility ofthe County's Waste Management Authority and localjurisclictions. The Gity of Dublin presently contracts with a private qompany for residential anq cOl11IIlercial garbage collection within the city limits. When ~exation taJ.<:es pls,ce, this private company will aIsoprovide wastecollection.services to the area. PARKS AND RECREATION The annexation area is currently under the jurisdiction of the East Bay Regional Park District (EI3RPD): The annexation area which toWs approximately 13 .6s,cres (Quarry Lane Schooland K,obold property) lies within the Eastern Dublin Specific Plan area; The annexation site is under private ownership and no park facilities exist in the area. -Once annexation takes place EBRPD will continue to provide regional park services to the area. Provision of local and POl11IIlunityparks, park maintenance and organization of recrea,tional services ~1l be the responsibility of the City of Dublin. In 1994, the City of Dublin adopted a parks and recreation master plan to provide park facilities for future residents. of Eastern Dublin, inCluding the proposed anne~ation area, To date, the first phase of a 50-acre CommunitYPl:1!k (Emerald. Glen Park) was recently opened to the 5 '11/ ~ J.83 public. UTILITIES Electricity is currently supplied to the annexation area by P. G. & E. Maintenance of street lighting will be by the City of Dublin. Telephone service is currently provided to the annexation area by Pacific Bell. Both P. G. & E and Pacific Bell are able to expand service to accommodate any future development of the annexation area. STREET MAINTENANCE Street maintenance and sweeping services will be provided to the annexation area by the City of Dublin. These services are currently the responsibility of the County of Alameda. LIBRARY The annexation area is served by Alameda County Library system and will continue to be after annexation. While this service will initially be provided by the existing branch library 10cated on Amador Valley Boulevard. . The City of Dublin plans to begin construction of a new 37,000 square foot library to be located at the Civic Center in 2001. The Library is expected to open in January 2003. TRANSIT There are currently no transit lines' which directly serve the annexation area. The Livermore / Amador Transit Authority (LA VTA) operates Wheels buses that provide local bus services throughout Dublin, including service to the Dublin/Pleasanton BART Station. The East Dublin BART train system provides convenient service to the City of Dublin and the Station is located approximately 3 miles southwest of the annexation area. FINANCING Any future development of the annexation area, including Phase 2 of the Quarry Lane . School and residences on the Kobold property will require the extension of public improvements from Tassajara Road (south of the city limits) to the annexation area. The financing of capital improvements, including roadway improvements, water, sewer, drainage and flood control will be funded as part of the private project costs. Payment of these costs will be the responsibility of the landowner / developer. It is estimated that the cost of providing public services to the Eastern Dublin Area (including the annexation area) will exceed revenues over the next several years. This projection is consistent with the Eastern Dublin Specific Plan's analysis which shows costs exceeding revenues in the short-term. However, if new development occurs within Eastern Dublin as anticipated, it is expected to generate revenues to the City which will exceed costs over the long-term as predicted in the Specific Plan. The City will require the proponent of the Quarry Lane School to enter into an agreement to pay, the school's proportionate share of any public services deficit and certain major road improvements consistent with the goals and policies of the Specific Plan. 6 ys a1f ;;33 PLAN FOR PROVIDING SERVICES POTABLE WATER WASTEWATER COLLECTION, TREATMENT AND DISPOSAL Quarry LaneIKobold Annexation Annexation 00-1 to Dublin San Ramon Services District October 2000 Dublin San Ramon Services District ("DSRSD" or "District") will provide potable water and wastewater collection, treatment and disposal services to the annexation area. As a condition of annexation to the District, it will require each owner in the annexing territory to participate in providing all detailed phasing plans and design of on site water and wastewater facilities. Off- site water facilities will be designed and constructed by the District, in conformance with its Major Infrastructure Policy (Exhibit 1 attached). Offsite sewer facilities will be designed and constructed by the developer in conformance with District standards. It is the District's understanding that the Quarry Lane School will make the sewer extension at its expense, as they will need the extension to proceed with Phase 2 of the school project upon annexation. Preliminary data on water and wastewater facilities needed to serve the annexation territory are provided herein and in attachments hereto. Since no development approvals are sought by virtue of this annexation application. no final approval of water and wastewater facilities or equivalent connection estimates are granted by virtue of this report. The fmal approval of the water and/or wastewater facilities and permits needed to ultimately serve the annexation territory may only be granted by the District. WATER Potable Water No water service is currently provided to the annexation territory by DSRSD. The residence and Phase 1 Quarry Lane School in the annexing area currently use well water. Upon annexation, and construction of Phase 2 of Quarry Lane School, the entire Quarry Lane site, and all new development in the annexing territory, will receive water service from DSRSD. In accordance with the District Code, existing homes can remain on wells unless a parcel is proposed for subdivision. All subdivision development shall be provided with public (DSRSD) water as provided by County Health regulations. The District has determined that the annexing territory will require a projected maximum of 14.5 acre feet of potable water per year (assuming maximum General Plan build-out of the Kobold parcel). The District has determined that its water supplies are adequate to meet this demand. The following discussion supports that conclusion. ATTACHMENT A TO EXHillIT B-5 Yrf, a6 ~,S.3 DSRSD currently obtains all of its water supplies under the terms of an Agreement with Zone 7 of the Alameda County Flood Control and Water Conservation District ("Zone 7" or "Zone"), which wholesales treated local surface water, groundwater and imported water to various Livermore/Amador Valley retail water agencies. DSRSD renegotiated its Water Supply Contract with Zone 7 in 1994. The renewed contract will be for a term of 30 years and is renewable upon expiration. It obligates Zone 7 to supply all the water requested by DSRSD for use within the Zone 7 boundaries subject to its availability. It further provides that any area duly annexed to the District may be served with water obtained from Zone 7. The Agreement also provides DSRSD with the ability to seek and secure alternative sources of supply through mechanisms such as water transfers, to construct wells and pump from the groundwater basin which Zone 7 manages and to recycle water within its service area. The Water Supply Contract requires the District to submit to Zone 7 an annual water request profile, requesting supply requirements for the ensuing calendar year, and projecting requirements for the five. (5) year period following the year in which the request is made. The 2001 supply year request made by DSRSD to Zone 7, includes adequate water supplies to accommodate the Quarry LaneIKobold annexation. The District has completed an Update to its Urban Water Management Plan (UWMP). The UWMPwas approved by the Board of Directors on May 16,2000. The UWMP includes demand projections for all expected future development demands, incIuding the annexing territory . The Zone 7 Board of Directors adopted the Year 2000 Update to its Urban Water Management Plan on October 18,2000. The Plan states that Zone 7 will manage and augment as necessary its supply sources so as to provide its retailers with 100% of the water they may request, even in critical drought years. It further states that Zone 7 will manage its local groundwater supplies to provide 75% of total system demands, even in critical drought years, so as to minimize reliance on State Water Project sources which could be curtailed during a catastrophic emergency or extended drought. Zone 7 has increased its wholesale water connection charge to provide the funding for the development of the necessary additional water resources and the construction of the needed infrastructure to meet its commitments made by its retail water supply agreements. The District has recently completed a Water Master Plan Update for its entire water service area, as well as its Sphere ofInfluence. The Master Plan shows a 14" supply main, which will be required in Tassajara Road to supply water to the annexing territory. The supply main is illustrated on Exhibit 2. Recycled Water Ordinance 280 of the DSRSD Board of Directors sets out policies and priorities for the required provision of recycled water. It provides that within the potable water service area of the District, all appropriate irrigation demands must connect to recycled water facilities as they may . reasonably be available. Recycled water is a requ~red addition to the potable source for those specified acceptable irrigation uses. y-? % ~3. Although the landsc~pe irrigation represented by the school would be an acceptable recycled water use pursuant to. Ordinance 280, it bas been determined that the e)(isting potable water well currently utilized for Phase lofth,e Quarry Lane School is aciequateto be used for irrigation water when :Bbase.2is constructed. Therefore, although the project's irrigation demands will not be required to conn~ctto the District?s recycled water system, neither will they become a demand upon the District's po:tt,ble supplies. It is not expected that any recycled water will be used by . the KoboIdp:t:operty, as any dev~Iopment on that property would be low or medium density residential. WASTEWATER Wastewater services for the annexation territory will be provided by DSRSD. The District has been actively planning to provide wastewater collection, treatment and disposal services to the east Dublin service area since 1 Q93. Wastewater flows for the annexation territory are estim~ted as follows: Quarry Lane School: . Approximately 4 g~lol1s per day per student/staff . 1,005 Staff and students . 4,020 gallons per day (gpd) average flow (4 gal X 1005) . Approximately 18 equivalent single family connections (4,020 gpd / 220 gal per ,equivalent connection) Kobold. PrQperty: . One existing single family dwelling . Potential for maxhnum of25 homes (terrain dictates highly unlikely morethan 8 additiol1al homes) . · At 220 gpd per hOl11e,wastewater flow of 5,500 gpd Total maximum flow: 9,520 gpd Equivalent connections: 43 Wastewater Collection All development within the annexation territory will be connected to the DSRSD collection system. The Phase 1 of the Quarry Lane School currently uses a septic tank and leach field system as permitted by Alameda County and approved by the Zone 7 Flood Control and Water Conservation District. In accordance with the District Code, existing homes (the Kobold residence) will be required to connect to DSRSD mains when those mains are.within 200 feet of the property line, or when any subdivision of land is ~pproved, which conforms with the County Health Department regulations. Similarly, the Phase 1 and 2 Quarry Lane projects will be required to connect to the District's collection system upon annexation and extension of <f gr at .},:?.3 collection system lines by Quarry Lane School. The District has completed an update to its Wastewater Collection System Master Plan, which calls for a sewer line in Tassajara Road adjacent to the annexing area to serve development in the area. The sewer extension will flow from northto south toward the existing Dublin Ranch development area, within the current District boundary. The sewer line is not designated as District Major Infrastructure, therefore it mu,st be constructed by development interests at their cost; the Quarry Lane School will be required to complete the sewer extension as a condition of the Phase 2 school construction. Currently, a 15" diameter sewer has been extended to within 120 feet of the annexing area. Extension of that 15" sewer is feasible to provide wastewater services to the annexing territory. Exhibit 3 (Figure 3-1 of the DSRSD Wastewater Collection System Master Plan Update) shows the sewer extension required to provide service to the annexing territory. Wastewater Treatment Treatment for sewage generated by development in the annexation territory will be provided by the DSRSD Wastewater Treatment Plant located south of Stone ridge Drive in Pleasanton. The plant is owned and operated by DSRSD and presently serves the cities of Dublin and Pleasanton and the southern portion of San Ramon.. It currently has an average dry weather flow capacity of 11.5 mgd. . Expansion of the plant is currently under construction and is scheduled for completion by the end of2003. The expansion will result in an average dry weather flow capacity of 17.0 mgd. Planning and development projections indicate that the current wastewater treatment capacity will be adequate beyond the planned completion of the expansion project. Wastewater Disposal Currently, disposal of all treated wastewater from the DSRSD plant is through export to San Francisco Bay via the Livermore Amador Valley Wastewater Management Authority (LA VWMA) and East Bay Dischargers Authority (EBDA) systems. DSRSD's current allotted capacity in the LA VWMA and EBDA systems is not sufficient for all planned and approved development within DSRSD's sphere of influence, however, DSRSD has obtained a lease of disposal capacity from the City of Livermore, and retains an option for an additional lease from the City of Pleasanton. There are currently a total of approximately 780 equivalent dwelling units of capacity remaining from the Livermore portion of this leased capacity. These capacity leases allow DSRSD to accept additional connections, while design and construction of major disposal capacity improvements is completed. The disposal capacity ofDSRSD is therefore adequate to accommodate the annexing territory. DSRSD has approved and constructed the Clean Water Revival (CWR) wastewater disposal project, but has not placed the project into operation. DSRSD could provide up to 1.0 mgd of wastewater disposal capacity via this project (after the 5th year of full operation, capacity could be increased to a maximum of2.5 mgd upon approval of the Regional Board), to accommodate approved growth.in DSRSD, including the proposed annexation. However, the District will not need to implement this disposal option unless the currently planned expansion of LA VWMA Lj l' z;zf ;? 3..3 facilities is not constructed in accordance with its current schedule, as explained below. An expansion of the LA VWMA disposal system has been approved by its member agencies (Pleasanton and DSRSD; Livermore currently will participate only in repair of the LA VWMA facilities, and may participate in expansion in the future). Design of the expansion is complete, and construction of the repair/expansion awaits the member agencies' approval of the financing plan (expected by December, 2000). The LA VWMA expansion will allow the full utilization of wastewater treatment capacity of the current plant expansion to 17.0 mgd. H:\ENGDEPT\Dept Items\PLANNER\quarryln\PLANSVCS 10-25-00.DOC .

SABRI ARAC FOR THE QUARRY LANE SCHOOL PROJECT THIS AGREEMENT dated for identification this 21st day of November, 2000, is entered into by and among the City of Dublin, a municipal corporation, (lithe City") and Dr. Sabri Arac ("Developer"). Recitals 1. In 1993, the City Council of the City adopted the Eastern Dublin General Plan Amendment and Eastern Dublin Specific Plan (flthe Specific Plan").The Specific Plan provides a planning framework for the future growth and development of approximately 3,300 acres (collectively, "the Specific Plan Area"). . . 2. The General Plan and the Specific Plan include goals ~md policies to prevent development within the Eastern Extended Planning Area and the Specific Plan Area (hereinafter collectively "Eastern Dublin") from drawing upon and diluting the fiscal base of the remainder of the City. 3. The Developer owns certain property (lithe Quarry Lane Property") within the Specific Plan Area described more particularly in Exhibit A, which is incorporated herein by reference. Developer received approval for a private school on the property for 200 students (Phase 1) from Alameda County. Developer has applied to City for annexation to the City of the Quarry Lane Property and Prezoning for construction of additional building and operation of Phase 2 of a private K-12 school for all additional 750 students, known as the Quarry Lane School (the "Project"). . 4. On December 30, 1999, the Developer filed an application with the City to prezone and annex to the City the Quarry Lane Property and certain other land within the Specific Plan Area owed by Michael O. Kobold (collectively, lithe Annexation Area"), all of which is shown on the map attached hereto as Exhibit B and incorporated herein by reference. The Developer did not submit any development plans with the application for the Kobold property. Annexation Agreement Between City of Dublin and Dr. Sabri Arac- Quarry Lane School EXHIBIT Govemb:~~~,~~~~ sg ~ J,:33 5. It is estimated that the cost of providing public services to the Eastern Dublin Area .at a level consistent with services provided within the City could exceed revenues generated to the City from property within the Eastern Dublin Area. 6. If new development occurs within the Eastern Dublin Area as anticipated, it is expected to generate revenues to the City which will reduce and, in the near future, eliminate the above-described potential deficit. However, even with development, deficits may occur in early years. Consistent with the goals and policies of the General Plan and Sp~cific Plan, Developer will pay City Developer's propo.rtionate share of any such deficits, as provided herein. Developer's proportionate share shall be .42% (.42 percent) which is the percentage which the Annexation Area (13.75 acres) is of the lands within the General Plan Amendment area which have not been annexed to the City as of the date hereof (1,929.84 acres) plus the Dublin Ranch Project (1,363.29 acres ). Because Developer proposes construction and operation of the Project on the Quarry Lane Property and City anticipates receiving revenues from such project, City will require payment by Developer of its proportionate share of any deficit only from the time a new fire station is opened to serve Eastern Dublin, which City anticipates will result in a deficit. 7. Certain improvements to the 1-580/TassaJara Road Interchange ("Interchange Improvements") are required to be constructed in order to facilitate development on the Annexation Area. City has previously entered into agreement for funding for construction of the Interchange Improvements with developers of property. within the City. Pursuant to these agreements, four developers (Alameda County Surplus Property Authority, Jennifer Un, Greenbriar Homes and Mission Peak) have agreed to advance at least $11,863,969 to City for the Interchange Improvements. Development of the Annexation Area will benefitfrom construction of the Interchange Improvements. 8. Development of the Project will result in additional traffic on Tassajara Road North of the Project. This agreement requires the Deyeloper to prepare a precise alignment for Tassajara Road. 9. The purpose of this agreement is to: (a) assure the City that the Developer will contribute its proportionate share of any defi.cit between revenues and expenses for the Annexation Area; (b) provide for Developer contribution of its prorata share of the cost of design and construction of the Tassajara Interchange improvements; and (c) set forth the Developer's obligation for preparation of a precise alignment for Tassajara Road from the city limit line to the proposed intersection with the north boundary of the property to the north, all prior to the City initiating annexation of the Quarry Lane Property. Annexation Agreement Between City of Dublin and Dr. Sabri Arac - Quarry Lane School Page 2 of 6 November 13, 2000 5 '1 ~ ;;.3.3 . AGREEMENT NOW THEREFORE, in consideration of the mutual promises and conditions contained herein, the Parties agree as follows: Section I. General Fund Shortfalls . A. The Developer's Payment Obligations; Definitions. Developer shall pay the City .42% (.42 percent) of the deficit, if any, between Public Service Costs and General Revenues. "Public Service Costs" shall mean t~e general fund cost of providing public services to the Eastern Dublin Area at a level consistent with public services provided within the incorporated area of the City prior to the annexation. "General Revenues" shall mean those revenues deposited to the City's general fund from property and inhabitants within the Eastern Dublin Area. "Eastern Dublin Area" shall include all lands within the Eastern Dublin General Plan Amendment area which are within the City limits of Dublin. B. Duration of Payment Obligations. The Developer's obligation under this Section I shall beginwhen the new fire station to be constructed in Eastern Dublin (Fire Station 18) becomes operational and shall terminate when there is no deficit but in no event by June 30, 2010 ("Deficit Period"). C. Annual^Fiscal Analyses. The City shall prepare a .fiscal analysis each year during the Deficit Period to estimate the amount by which the Public Service Costs will exceed General Revenues. The fiscal analysis will be prepared on a fiscal year basis (July 1 to June 30) and will calculate the deficit for the preceding .fiscal year. D. Payments to the City. No later than October 1 of each year during the Deficit Period, Developer shall pay to City .42% of the deficit between Public Services Costs and General Revenues for the preceding fiscal year, based on the fiscal analysis, plus .42% of the cost of the fiscal analysis described in Section LC. E. Security for Payment. No later than approval of Site Development Review for Phase. 2 of the Project, Developer will provide the City with security in an amount and form satisfactory to the City Manager, to become effective once the Annexation Area becomes part of the City, to secure the payments to the City described in Section I.D above. The security may consist of a letter of credit or similar instrument. F. Reimbursement From Other Property Owners. The City shall consider fair and appropriate ways of reimbursing the Developer some of the amounts Developer may be required to pay under this Section I from the owner of the Kobold property, which is the only other property included in the Annexation Area which is not owned by Developer. To the extent permitted by law, the City shall require owners of the Kobold property who seek City approval of development entitlements for such property to pay a fair and proportionate share of the amounts which Developer is required to pay pursuant to this Section I. Annexation Agreement Between City of Dublin and Dr. Sabri Arac - Quarry Lane School Page 3 of6 November 13, 2000 66 ~ ~j3-- Section II. Payment to City for Tassajara Road Interchange A. Advance of Monies by Developer. Prior to the Council, acting as the "conducting authority," adopting a resolution ordering the annexation (reorganization) and provided the ordinance prezoning the Quarry Lane Property for the Project,has become effective, Developer will pay to City the sum of Four Hundred Nine Thousand Five Hundred Dollars ($409,500). B. Use of Monies by City. City will use the monies paid by Developer pursuant to this Agreement, together with any interest earned thereon, for construction of the I.nterchange Improvements. As used herein, "construction" shall include preliminary engineering, preparation of project study report,. project report, plan specifications and estimates, engineering, environmental documentation and review, right-of-way acquisition (if necessary), permits, processing, utility relocation, construction, construction inspection, project management, and inspection. City shall be under no obligation to use. the monies paid by Developer until such time that City has adequate monies to construct the Interchange Improvements. C. Credit Against TIF. City will provide a credit to Developer in the amount of Developer's payment of monies hereunder, to be used by Developer against payment of the Eastern Dublin Traffic Impact Fee (''TIF''). This agreement shall be deemed to be the creditlreimbursementagreement required by Section V(A) of the TIF Guidelines (as adopted by Resolution 23-99). All aspects of the credits shall be as described in the TIF Guidelines, including the right to convert any unused credits to a right of reimbursement, subject to the following provisions: (a) the Developer shall pay an administrative fee of one-half of one percent or $1,000 whichever is greater; (b) the credit shall be granted at the.time Developer.makes payments of money pursuant to this agreement; (c) the credit shall be in the amount of $409,500 (d) the credit may be used only against the Category 1 TIF Fees; and (e) the credit may be used once it is granted. .;; Section III. Preparation of Precise Alignmentfo'r Tassajara Road Prior to transmission by the City Clerk of a certified copy of any City Council resolution approving the reorganization, which includes annexation to the City of the Annexation Area, Developer shall submit to the City Engineer a precise alignment for Tassajara Road from the existing northerly city limit line to the proposed intersection . with the north boundary of the property immediately to the north of the Quarry Lane Property, currently owned by Robert Nielson, in a form acceptable to the City Engineer. The precise.alignment shall be in a form which can be recorded, as required by Dublin Municipal Code Chapter 7.68. The precise alignment shall be consistent with the precise alignment for Tassajara Road south of the city limit line. The precise alignment shall be for the ultimate width of Tassajara Road (six lanes) but shall propose construction initially of only four lanes within the right-of-way for the ultimate road width.

Initial Study In trod uction This Initial Study has been prepared in accord with the provisions of the California Environmental Quality Act (CEQA) and assesses the potential environmental impacts of implementing the proposed project described below. The Initial Study consists of a completed environmental checklist and a brief explanation of the environmental topics addressed in the checklist. Applicant Dr. Sabri Arac President Quarry Lane School 3750 Boulder Street Pleasanton, CA 94566 925-846-9400 Project Location and Context The project site is located on the east side of Tassajara Road approximately three miles north ofI-580. The site addresses are 6363 Tassajara Road and 6237 Tassajara Road. Assessor's Parcel Numbers include 985-0002-0006-01,.985-0002-005-01 and -02. The site encompasses two parcels of land, the Quarry Lane School property, and the Kobold property immediately south of the school. The total site includes approximately 13.6 acres of land. Existingsite uses include the Phase I construction of the private Quarry Lane School and an existing building (Villa Tassajara) that has been incorporated into the QuarryLane School as the administration building. A single family residence, landscape contracting business and plant nursery exists on the Kobold property south of the school site. The project site contains moderate to steep topographic features, with natural (pre-graded) elevations ranging from approximately 400 feet above sea level adjacent to Tassajara Road to- approximately 564 feet above sea level on the northeast comer of the site. An unnamed tributary of Tassajara Creek forms the southerly boundary of the site. Exhibit 1 depicts the location of the project area in context of the larger City of Dublin and Exhibit 2 . shows the detailed site location. Both properties comprising the project site lie within the unincorporated portion of Alameda County, although within the City of Dublin's sphere of influence. Annexation to the City of Dublin and Dublin San Ramon Services District (DSRSD) is proposed as part of the project. The proj ect site is located within the Eastern Dublin Specific Plan/General Plan area. This. Specific Plan/General Plan was adopted by the City of Dublin in 1994 for the purpose of directing long-term land use, circulation, infrastructure and environmental protection for 3,302 acres ofland located east of the central portion of Dublin and north of the 1-580 freeway. At full build-out, the Eastern Dublin planning area would allow a range of residential, commercial office, employment and open space uses. City of DUblin Initial Study/Quarry Lane School P A 99-064 Page 2 July 2000 '7 ~ at ';{33 Property south of the project site has been recently developed with single family residential dwellings as part of Dublin Ranch. A custom single family dwelling on a large lot has been constructed northeast of the site. Other properties in the vicinity of the site remain vacant. Project History As noted above, both of the two parcels comprising the project site lie within the unincorporated portion of Alameda County. In April 1999, Alameda County approved a rezoning to the PD-Planned Development District to allow an initial phase of development for the Quarry Lane School, consisting of IS ,600 square feet of .floor area for day care, preschool and elementary grades with a maximum of 200 students. The school is a private school; water and sewer utilities are also private (on-site well and septic facilities). Construction of these facilities are currently on-going with opening of Phase I planned for August 2000. An Environmental Impact Report (Quarry Lane School, Environmental Impact Report for . the 2060th Zoning Unit, August 1998, SCH # 97122109) was certified by the County prior to approving the rezoning and development application. The ErR included the fun buildout of the private 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. However, the site plan for the second phase of development for the Quarry Lane School has since changed as part of the development application to the City of Dublin. The owner of the school now requests approval to construct Phase II of the school which includes additional classrooms, a gymnasium, recreational facilities and other features :which will increase the need for public services and facilities beyond that available from private facilities. Annexationto the City of Dublin and DSRSD is therefore required to obtain a higher level and range of services that is currently available. Since the Knox-Cortese Act requires properties proposed for annexation to.be contiguous with boundaries of the jurisdiction to which annexation is proposed. In this instance, the Kobold property is proposed to be included in the annexation action, since it is an intervening property between existing City limits and the Quarry Lane School site. Project Description The proposed project includes a number of related land use applications to allow the development of . additional phases of the Quarry Lane School, to include the construction of 66, 600. square feet of floor area to accommodate new classrooms, a gymnasium, new recreational. play fields to house a maximum of 750 students. At full build-out, there would be 950 students and 55 faculty and staff on the site. Parking would be provided for 172 vehicIes..Landscaping would also be provided on the site. The following table summarizes the amount of construction proposed for each phase of project development: .

Exhibit 4 shows proposed building elevations. . , Construction of the second phase would require grading of the rear portion of the site to provide relatively flat areas for playing fields, parking and drive areas and new classroom space. A preliminary plan has been submitted to the City of Dublin showing the proposed grading for the school site. (see Exhibit 5). Briefly, the applicant proposes to recontour the rear portion of the site so that the existing small hill on the site is cut, a combination of cut and fill is used. behin.d the new classroom building to create a flat pIayfield site and a steep downslope is created along the southerly property line to meet natural grade. Several retaining walls would be required as part of the grading plan. The walls would range in size from less than one foot to a maximum height of 14 feet. The estimated amount of material moved as part of the school development project would be 87,401 cubic yards. Construction of Phase II improvements would begin following approval by the City of Dublin and completion of the annexation process. Preliminarily, the school operator anticipates opening Phase II in September, 2002. At this time, no development is planned for the Kobold property. The following entitlement requests have also been filed. by the applicant to allow phase two of the development of the private school to proceed. PD-Planned Development Prezoning and Stage 1 and 2 Development Plans The applicant has also proposed a PD-Planned Development prezoning for the project site. Existing zoning is Alameda PD (Planned Development) for the school site and "A" (agricultural) for the nursery site to the south. ' Proposed City of Dublin prezoning is PD-Planned Development (School) and would include a Stage 1 and 2 Development Plan. The PD-.Planned Development also establishes standards and regulations governing the future use, development, improvement and maintenance of the site, in accord with Chapter 832 of the Dublin Zoning Ordinance. Proposed prezoning for the Kobold site is PD-Planned Development (Residential and Open Space); however, no development is proposed at this time on this site. CIty of Dublin Initial Study/Quarry Lane School P A 99-064 Page 4 July.2000 'i t/ ~ ;;, 33 Since both sites lie outside. of the City of Dublin corporate boundaries and annexation has been requested, proposed zoning actions are prezoning actions until the annexation can be finalized. The proposed zoning . . would become effective at the time the annexation process is complete. Development Agreement Approval of a Development Agreement is also part of the entitlement process for the project as required by the Eastern Dublin Specific Plan. Items typically included in the Development Agreement include, but are not limited to, the financing and timing of infrastructure; payment of traffic, noise and public facilities impact fees; improvement of roads and general provisions. Proposed Reorganization (Annexation) To implement the proposed development project, the property owner ofthe Quarry Lane schoolhas submitted a request to incorporate the entire site into the City of Dublin. Pursuant to the Knbx-Cortese Local Governmental Reorganization Act, a municipal reorganization would be required to annex the site to the City of Dublin and Dublin San Ramon Services District. Although the initial phase of school development has occurred in the unincorporated portion of Alameda County, a higher level of public services, including water and sewer service, is needed than is available from private water wells and on;.site septic systems. Annexation to both the City as DSRSD is therefore required. '.. Since the Knox-Cortese Act requires properties proposed for annexation to be contiguous with boundaries of the jurisdiction to which annexation is proposed. In this instance, the Kobold property is proposed to be included in the annexation action, since it is an intervening property between existing City limits and the Quarry Lane School site. The proposed reorganization can be initiated by either the City of Dublin or by the affected property owners and would then be approved by the.Alameda County Lo.cal Agency Formation Commission (LAFCO). The action would be complete when accepted by the Secretary of State. Site Development Review Approval of a Site Development Review permit is also part of the entitlement process for the project, pursuant to Chapter 8.104 of the Dublin Zoning Ordinance. The purpose of Site Development Review is to pro+note the orderly, attractive and harmonious development within the City and to ensure compliance with all applicable development regulations of the Zoning Ordinance.

X Aesthetics - Agricultural X Air Quality Resources - Biological Resources X Cultural Resources X Geology/Soils .- Hazards and Hydrology/Water - Land U sel Planning - Hazardous Materials X Quality - Mineral Resources X Noise - P opulation!Housing X Public Services - Recreation X Transportation! Circulation X Utilities/Service - Mandatory Findings Systems of Significance Determination (to be completed by Lead Agency): On the basis of this initial evaluation: _ I fmd that the proposed project could not have a significant effect on the environment and a Negative Declaration will be prepared. 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 the mitigation measures described on an attached sheet have been added to the project. A Negative Declaration will be prepared. ~ I find that although the proposed project may have a significant effect 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 earlier analysis as described on the attached sheets, if the effect is a "potentially significant impact" or "potentially significant unless. mitigated." An Environmental Impact Report is required, but must only analyze the effects that remain to be addressed: _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 all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR, induding revisions or mitigation measures that are imposed on the proposed project.

For: City of Dublin Initial Study/Quarry Lane School PA 99-064 Page 14 July 2000 yL/ 06 ,.2.:3J 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 parenthesis 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 lik~ 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 factors (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, 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) "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "potentially significant impact" entries when the determination is made, an EIR is required. 4) . "Negative Declaration: Potentially Significant Unless Mitigation Incorporated" implies elsewhere the incorporation of mitigation measures has reduced an effect from "potentially significant effect'! 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.

City of Dublin Initial Study/Quarry Lane School P A 99-064 Page 26 July 2000 9(, % ~33 Attachment to Initial Study Discussion of Checklist Legend PS: Potentially Significant LS/M: Less Than Significant After Mitigation LS: Less Than Significant Impact NI: No Impact I. Aesthetics Environmental Setting The project site contains the initial phase of the Quarry Lane School, currently under construction. Construction has caused recontouring of the topography adjacent to Tassajara Road and conversion of the previously vacant site to an urban use. The property to the south contains a single family dwelling, landscaping contracting business~ nursery and related outbuildings. Properties surrounding the project site are generally vacant, however, the City of Dublin has approved urban development on major portions of the Dublin Ranch to the east and south of the school site. A custom single-family dwelling on a large lot exists to the northeast of the site. The pr<:oject site is located within the Tassajara R.oad scenic corridor, so designated by both the City of Dublin and Alameda County. The previous ElR certified by the County for the proj ect identified a number of mitigation measures to ~nsure potential visual impacts ofproj~ct construction are reduced to a level of less-than-significant, however, the overall visual impact of the project, including re-grading of the site and . construction of permanent buildings, could not be mitigated to a less-than-significant level. A number of mitigation measures have been included in the County EIR to deal with visual and aesthetic impacts. These are summarized below: · Reduce the. amount of site grading; . · Incorporation of rounded features as part of exterior building design; · Development of a planting plan using native and adapted plants for the site; Replanting the site as soon as possible after grading and construction; · Designing buildings and landscaping to be compatible with surrounding uses and rural character of East Dublin; · Developing a fencing and sign plan compatible with the rural character of the area; · On-site lighting to use full cutoff-shielded lights, use low-wattage lights, minimizing amount of illuminated areas and consider a "dark campus" concept. Proiect Impacts and Mitigation Measures a) Have a substantial adverse impact on a scenic vista? LS/M. Approval and construction of the proposed project would convert the rear portion of the site from a natural area to an urban use. The front portion of the site has recently been converted from rural t6 an urban use. To minimize the visual impacts of development in the Tassajara Corridor, the City of Dublin prepared Eastern Dublin Scenic Corridor Policies and Standards in 1996. A portion of the Guidelines focus on the Tassajara Creek Valley area, which includes the proj ect site. For this area, the Guidelines suggest the following policies and standards: City of Dublm Initial Study/Quarry Lane School P A 99-064 Page 27 July 2000 9'7 ~ ;?:33 Policy 6: Emphasize valley character by creating viewpoints and view corridors to knolls, foreground hills and to Tassajara Creek. Standard 6.1: Allow intermittent views from Tassajara Rd. to the hills, knolls and creek. Standard 6.2: Where Tassajara Creek intermittent branch crosses Tassajara Road, maintain views to the creek and riparian vegetation and to the open space to the east. · Policy 7: Emphasize the semi-rural character of the area Standard 7.1: Streetscapes should reinforce semi-rural ambience Standard 7.2: Site and articulate buildings to provide interest and reduce perceived density · Policy 8: Provide transition to Tassajara Village Standard 8.1: North of the creek crossing at Tassajara Road, reintroduce more formal village elements. This potential impact was addressed in the Eastern Dublin EIR (Impact 3.8C, Obscuring Natural " Features and Impact 3.8F, Alteration of Visual Character of Flatlands) and it was determined that no mitigation measures would reduce this impact to a less-than-significant level. Therefore, the EIR . concluded this impact would be a potentially significant irreversible change and a Statement of Overriding Considerations has been approved for this impact. The following measures are recommended to reduce impacts to a less-than-significant level: Mitigation Measure la: The project developer shall adhere to applicable Tassajara Creek Valley Scenic Corridor Policies and Standards for development phases proposed in the City of Dublin. In addition, mitigation measures included in the Alameda County Environmental Impact Report to reduce visual impacts, including but not limited to limiting site grading, replanting graded slopes and similar elements shall be complied with. Mitigation Measure Ib: The project developer shall adhere to the following methods, as approved by the City of Dublin Planning Department: a) On-site retaining walls shall be landscaped with fast-growing evergreen vines. " b) The chain-link fencing around " sports field and on top of retaining walls shall be of green vinyl cladding to reduce visibility and reflectiveness. c) Landscaping along the project frontage shall comply with the City of Dublin Streetscape Master Plans. Mitigation Measure 2: The appearance of the steep slope on the southeast corner of the site (approximately 2:1 slope) shall be reduced through the following methods, as approved by the City of Dublin Planning and Public Works Departments: a) The landscape plan for the project shall designate vegetation suitable for slope areas to ensure slope stability. " " . b) The base of this slope shall be landscaped with dense, fast growing appropriately spaced vertical trees. Tree wells shall be provided to protect trees and encourage healthy growth. City of Dublin Initial Study/Quarry Lane School PA 99-064 Page 28 July 2000 9'% 06 ~jj b) Substantially damage scenic resources, including state scenic highway? LSIM. The project site is located adjacent to Tassajara Road, which is designated as a scenic corridor in the Eastern Dublin Specific Plan/General Plan Adherence to Mitigation Measures 1 and 2, above, will reduce potential impacts to a less-than-significant level. c) Substantially degrade existing visual character or the quality of the site? LS. This impact was addressed in a Statement of Overriding Considerations in the 1994 Eastern Dublin EIR. Therefore, this impact is less-than-significant and no further analysis is required. Adherence to Mitigation Measures 1 and 2 will also serve to reduce impacts to the existing visual character of the area. d) Create light or glare? LS/M. Construction of the proposed project would increase the amount of light and glare due to new street lightirig~ parking lot lighting, building security lighting and potentially lighting of the playfields. Although some level of new light sources have already been added to the site as part of Phase I construction, new lighting would result in negative aesthetic impacts through-the "spill over" of unwanted lighting onto adjacent properties, streets and other areas that are not intended to be lighted. Implementation of the mitigation measures contained in the Alameda County EIR for Phase I of the project is recommended to reduce spillover of lighting impacts for Phase II to a level of less-than-significant. Mitigation Measure 3: The folloWing measures shall be incorporated into plans and school operations: a. Pole-mounted lights shall be equipped with cut-off lenses and oriented down toward interior streets to minimize unwanted light and glare spill over. b. Building security lighting and other'lights shall be directed downward. c. Exterior lighting shall be dimmed or turned off during off-hours. d. All exterior glass panels shall be of non-glare manufacture. e. The project developer shall also work with the City of Dublin Police Services Department to investigate the concept of the "dark campus" concept, if such a concept is consistent with adopted City security ordinances. II. Agricultural Resources Environmental Setting The Eastern Dublin EIR notes that the school site is located on soils that are classed as "locally important farmland." Although the school site may have been under agricultural production at one time, Phase I of the Quarry Lane School is now under construction. The parcel to the south has been developed as a nursery, The Eastern Dublin Specific Plan has determined that loss of farmland oflocal importarice (Impact3.l/D) would be an insignificant impact should the Eastern Dublin Specific Plan/General Plan be approved and no mitigation measures would be needed. Proiect Impacts and Mitigation Measures a-c) Convert Prime Farmland, conflict with agricultural zoning or convert prime farmland to a non- agricultural use? LS. Although site soils are classed as locally important farmland, neither of the sites are in active agricultural production. The project site is also adjacent to future urbanized areas immediately to the east/south-east. Therefore, less-than-significant impacts with regard to agricultural resources are anticipated. . Page 29 July 2000 " City of Dublin Initial Study/Quarry Lane School P A 99-064 91 ~ ;<3.:3 III. Air Quality Environmental Setting Dublin is located in the Tri-Valley Air Basin. Within the Basin~ state and federal standards for nitrogen dioxide, sulfur dioxide and lead are met. State of California standards for other airborne pollutants, including ozone, carbon monoxide and suspended particulate matter (pM-1 0) are not met in at least.a portion of the Basin. ' The Quarry Lane School EIR, prepared by Alameda County Planning Department contains an air quality analysis for the full-build out of the school. The air quality section was prepared by Donald Ballanti, meteorologist and consulting air quality analyst. The air quality section concludes that development of the school wo.uld not result in any significant long-term operational air quality impact. There would be short- term air quality impacts associated with the project, primarily caused by grading of the site and release of airborne fugitive ,dust. Mitigation Measures included in the EIR to reduce short term air quality impacts to a less-than-significant level include frequent watering of the site during grading, use of dust palliative in place of water trucks where necessary, covering graded areas with buildings, landscaping or similar items. Mitigation measures have been included in the County EIR to deal with air quality impacts. These measures are summarlzed below: · Frequent watering of graded portions of the site, at least twice daily; · Use of dust palliative chemicals to stabilize graded areas; · Planting or paving of graded areas as soon as possible. Proiect Impacts and Mitigation Measures a) Would the project conflict or obstruct implementation of an air quality plan? LS. The proposed project would not conflict with the local Clean Air Plan adopted by the Bay Area Air Quality Management District, since the proposed amount of non-residential development have been included in Dublin's planned growth as part of Eastem Dublin Specific Plan/General Plan. Therefore, such impacts would, be less-than-significant. b) Would the project violate any air quality standards? LS. Short-term construction impacts related to implementation of the project, including grading and excavation, could result in exceedances of air quality standards established by the Bay Area Air Quality Management District (Eastern Dublin EIR, Impacts 3.11/ A and B). Adherence to Mitigation Measure 3.1111..0 and Mitigation Measure 3.11/2.0 contained in the Eastern Dublin EIR will reduce short-term air quality impacts to a less- than-significant level. These mitigation measures minimize the creation of fugitive dust during grading and construction activities and also mandate that construction equipment be kept in proper running order. The Eastern Dublin EIR concludes that potential air quality impacts related to construction equipment could not be mitigated to a less-than-significant impact and a Statement of Overriding Considerations was adopted for this impact. Similarly, potential air quality impacts related to mobile source emissions of Reactive Organic Gasses and Nitrogen Oxide, both precursor indicators of smog, and stationary source emissions were found to exceed regional air quality standards even with mitigation measures, and were included in the Statement of Overriding Considerations (Eastern Dublin EIR Impacts 3 .11/C and E). Since a Statement of Overriding Concerns was adopted for the previous EIR, such impacts would be considered less-than-significant for the purposes of this Initial Study. City of Dublin Initial Study/Quarry Lane School P A 99-064 , , Page 30 July 2000 J t7D ~ A 5~3 c) Would the project result in cumulatively considerable air pollutants? LS. The Eastern Dublin EIR identifies Mobile Source Emissions and Stationary Source Emissions as significant irreversible impacts. Generally such impacts are based on vehicular emission from future traffic within the sub- region as well as stationary sources. A Statement of Overriding Considerations was adopted for long-term impacts, therefore, no additional discussion or analysis is necessary. d,e) Expose sensitive receptors to significant pollutant concentrations or create objectionable odors? LS. Proposed land uses would include a private school with outside play and recreation areas. Although children are considered as sensitive receptors, existing air quality in the area meets state and local emission standards and implementation of mitigation measures for short term construction impacts would ensure that students would not be exposed to significant pollutants. Since the project site is proposed as a private school, there would be no release of objectionable odors, which are not considered as sensitive receptors. Therefore, less-than-significant impacts are anticipated with regard to potential impacts to sensitive recepto~s. IV. Biological Resources Environmental Setting The Eastern Dublin EIR indicates the biological character of the project site is "developed" and IInon- native grasslands.1I Non-native grasslands are characterized as introduced annual weedy species which have replaced native grasses and herbs in a grassland habitat. Introduced grass species include slender wild oat, ripgut grass, soft chess, foxtail and rattail fescue. Native and non-native grasslands on the west side of the school property have beendisturbed by grading and building" activities associated with Phase One construction of the Quarry Lane School. The Kobold site is developed with a single family dwelling and outbuildings associated with the landscape contracting , . business on the property. A tributary ofTassajara Creek forms the southern boundary of the site. The Eastern Dublin EIR identifies no known wetlands on the site nor the presence of rare, threatened or endangered animal plant or animal species (Figures 3.7B and C). However, a Red tailed hawk or other raptor nest is identified in the Eastern Dublin EIR as being located adjacent to the eastern boundary of the site. Proiect Impacts and Mitigation Measures a) Have a substantial adverse impact on a candidate, sensitive, or special-status species? LS. Based on information contained in the Eastern Dublin EIR, no candidate, sensitive or special-status species exist on the school site. However, based on information contained in the Eastern Dublin EIR, a raptor next may exist to the east of the Koboldsite to the south. Although no development is proposed on the Kobold site at this time, prior to future development on this property a preconstruction survey for raptor nests is required by Mitigation Measure 3.7/20.0 to 22.0 of the Eastern Dublin EIR prior to grading activities, with appropriate actions taken at time to ensure that any raptors would be protected. b, c) Have a substantial adverse impact on riparian habitat or federally protected wetlands? LS/M. Based on information contained in the Eastern Dublin EIR, there are no wetlands or riparian , features on the school site. There would therefore be no impacts to wetlands or riparian habitats on the school site. However, the southerly boundary of Kobold property is an unnamed tributary creek to Tassajara Creek to the west. A portion of the tributary creek is located on the Kobold site. Since City of DublIn Initial Study/Quarry Lane School P A 99-064 Page 31 July 2000 J CJ / z6' C?33 no development is being proposed at this time on the Kobold property, there would be no impacts to this watercourse or biological resources. Proposals for future development on the Kobold property will be analyzed for impacts to the creek and mitigation measures would be imposed at that time to ensure that any impacts to riparian habitat would be reduced to less-than-significant levels. The provision of utility lines to the site (including but not limited to water, sewer, natural gas and others) may result in impacts to the unnamed Tassajara Creek tributary during the construction phase of utility extensions. The following mitigation shall apply to the extension of utilities to the Quarry Lane School property: ' Mitigation Measure 4: The following measures shall be incorporated into construction plans and operations related to service line extensions to the Quarry Lane School area: a. Service providers shall coordinate construction plans with appropriate biological regulatory agencies (including but not limited to Army Corps of Engineers, Fish and Wildlife Service, California Department ofFish and Game, Regional Water Quality Control Board) b. Requirements of each of the regulatory agencies shall be followed to reduce impacts to the unnamed creek and Tassajara Creek. d) Interfere with movement of native fish or wildlife species? NI. The project site is substantially surrounded by a combination of vacant lands to the north and west with recently developed areas to the .south as part of Dublin Ranch. Future park and rural residential lands lie to immediate east. There are no stream courses on the school site that could be used as a wildlife migration corridor. , Although an unnamed tributary bisects the southerly portion of the Kobold property that could function as a wildlife corridor, no development is proposed for the Kobold site at this time. Future biological analyses will be conducted regarding potential wildlife corridors at the time development is proposed on the Kobold site. Therefore, no impacts are anticipated with regard to movement of fish or wildlife species. e, j) Conflict with local policies or ordinances protecting biological resources or any adopted lJabitat Conservation Plans or Natural Community Conservation Plans? NI. No trees are present on the school site. Although trees and a portion of an unnamed creek exist on the Koboldsite to the south, no development is proposed for this site at the present time. Therefore, there are no impacts with regard to local tree preservation ordinances or policies. The site is not located within the boundaries of any Habitat Conservation Plans. V. Cultural Resources Environmental Settin~ The Eastern Dublin area was surveyed in 1988 as part of the Eastern Dublin Specific Plan and associated EIR. Several potentially significant historic and archeological resources were identified in the eastern Dublin area. ' ' Proiect Impacts and Mitigation Measures a) Cause substantial adverse change to significant historic resources? NI. The site contains Phase I of the school (currently under construction), the Villa Tassajara and an older single family residence and outbuildings on the Kobold site. No known historically SIgnificant resources existon'the subject site. There would therefore be no impacts to historical, resources. ' City of Dublm Page 32 Initial Study/Quarry Lane School - July 2000 P A 99-064 /0::< 06 ~:3-:3 b, c) Cause a substantial adverse impact or destruction to archeological or paleontological resources? LS. The site is located near the former Santa Rita Rehabilitation Center site and the Chang Su-O-Lin properties on which archeological artifacts were found n the mid-1980's. Development of the school project could have an impact on subsurface archeological and/or palenotological resources. This would be a potentially significant impact. In the event that such resources are encountered. Mitigation Measure 3.9/5.0 and 6.0 contained in the Eastern Dublin Specific Plan EIR establishes procedures to be activated in the event archeological resources are encountered during grading for Phase Two of the school and future development on the project to the south. With adherence to these mitigation measures impacts to archeological or paleontological resources would be less-than- significant, should any be found. d) Disturb any human resources? LS. A remote possibility exists that human resources could be uncovered on the site during construction activities. With adherence to Mitigation Measures 3.9/5.0 and 6.0 any impacts would be less-than-significant. V. Geology and Soils EnvITonmenmlSetting This section of the Initial Study addresses seismic safety issues, topography and landform, drainage and erosion and potential impacts to localized soil types. Seismic The project site is a part of the San Francisco Bay area, one of the most seismically active regions in nation. The Eastern Dublin EIR notes the presence of several nearby significant faults, including the Calaveras Fault, Greenville Fault, Hayward Fault, and San Andreas Fault. The likelihood of a major seismic event on one or more of these faults within the near future is believed to be high. The geotechnical report indicates that the project site is not part of a Special Studies Zone for faults as identified by the State of California, however, previous geotechnical investigations of the area show inferred faults north of the site (identified as t4e IlMocho Faultll). The Mocho Fault was mapped by the California Division of Mines and Geology in 1974. and was later evaluated as part of the Alquist-Priolo Special Studies Zone. As part of this evaluation it was concluded that the existence of the Macho Fault was questionable and geomorphic features could be caused by differential erosion. A second thrust fault system has been inferred in the Coast Ranges of the Bay Area that may be seisimically active. A belt of faults and folds has been mapped in sedimentary rocks south of Mount Diablo, including one identified as the 111eading edge-blind thrust, Mount Diablo Domain." Further investigation of this inferred fault by Berlogar Geologic Consultants has concluded that the risk of ground rupture from this inferred fault is low within the project .area. Site Soils and Geology The site is within the Diablo Range, an elongare system of northwest trending mountains, hills, ridges and narrow intervening valleys formed 'within the Coast Ranges of Central California. The site is underlain by underlain by undifferentiated rocks belonging to the Contra Costa Group, Orinda Formation. The.Contra Costa Group consists of non-marine sedimentary rocks, which often have poor slope stability with landslides occurring in both soils and rocks on natural and man-made cut slopes. Page 33 ' July 2000 City of DUblin . , Initial Study/Quarry Lane School P A 99-064 /cj:8 15 ~33 Soils on the site consist of moderately expansive clays and silts, The more level western area of the site, near the Villa Tassajara, contain alluvium and colluvium from , nearby hillsides. The site includes two landslides that are shown on regional landslide maps. Portions of the site have been previously graded and a cut slope on the northern portion of the site appears to have experiences a small mudflow. Landform and Topography The Quarry Lane School site consists of a southwest facing hillside with a relatively flat topped hill in the center and a relatively level area along the western border, adjacent to Tassajara Road. The Kobold site is relatively fla.t with a gradual slope towards the unnamed tributary ofTassajara Creek to the south. Site elevations range from approximately 440 to 590 feet above mean sea level. Natural topographic conditions have recently been altered on the school property caused by construction of Phase 1 of the Quarry Lane School. Drainage Existing drainage on the site is generally sheet flow in a north to south direction. The County EIR includes a number of mitigation measures to deal with geologic impacts. These are surrfinarized below: Completion of a geotechnical report for the site, identifying appropriate construction methods and techniques consistent with generally recognized engineering principles; · Reduction in the amount of proposed site grading; · Review of the final grading plan by a geotechnical engineer; ~ Identification of specific methods to minimize risk oflandslides and expansive soils as part of the geotechnical report. Proiect Impacts and Mitigation Measures , a) Expose people or structures to potential substantial adverse impacts, including loss, injuryor death related to ground rupture, seismic ground shaking, groundfailure, or landslides? LS/M. The site is subject to ground shaking caused by a number of regional faults identified above. Under moderate to severe seismic events which are probable in the Bay Area over the next 30 years, buildings, utilities and other improvements constructed on the site would be subject to damage caused by ground shaking. 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 3.6/1.0 through 8.0 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 reduced ' to a level of less-than- significant. ' , As part of the project, the site is proposed to be graded to recontourthe site, allowing for the development of future buildings, the playfield, parking areas and landscaping. Grading would also occur to improve and control site drainage. Mitigation Measures 3.6/17;0-26.0 have been adopted as part of the Eastern Dublin Specific Plan EIR to reduce potential impacts to slopes to a level of less- than-significant. These mitigation measures require the preparation of site-specific soils and geotechnical reports, minimizing grading on steep slopes and adherence to Uniform Building Code and ot~er City requirements for grading. Nicholas Engineering Consultants have prepared City of Dublin Initial Study/Quarry Lane School P A 99-064 page 34 July 2000 /D'I art ~'3~ preliminary soils reports dated June 1,1999 and June 12,2000, that contains specific recommendations regarding grading, soil compaction and construction methods to ensure that future buildings and improvements adhere to applicable safety standards. Based on discussions with the Dublin Public Works and Building Departments, a fmal soils report must be prepared to ensure that all construction details of the school comply with Uniform Building Code requirements and engineering standards. Mitigation Measure Sa: Prior to issuance of a grading permit by the City of Dublin, the project developer shall submit a final soils report for review and approval by the City of Dublin Public Works and Building Departments. The final report shall include specific construction techniques to ensure consistency with generally recognized engineering standards. Mitigation Measure Sb: Prior to issuance of grading permit by the City of Dublin, the project developer shall submit a Slope Stabilization Program addressing the steep slape on the southeast corner of the site (approximately 1.5:1 slope). The Slope Stabilization Program shall include but not be limited to planning plans, compaction plans and appropriate measures to ensure stability of this slope The Dublin Building and Public Works Departments will use the soils report to review detailed construction plans for the project. Adherence to this mitigation measure will reduce potential landslide and ground failure impacts to less-than-significant levels. ' b) Is the site subject to substantial erosion and/or the loss of topsoil? LS. The Eastern Dublin EIR notes that an impact of constructing all ofthe land uses identified in the Eastern Dublin Specific Plan/General Plan would be an increase of erosion and sedimentation caused by grading activities. Mitigation Measures 3.6/27.0 and 3.6/28.0 requires that specific project developers prepare arid implement interim erosion plans as part of grading impacts. With adherence to these mitigation measures, potential erosion impacts will be less-than-significant. ' c-d) Is the site located on soil that is unstable or expansive or result in potential lateral spreading, liquefaction, landslide or collapse? 'LS. Based on the Nichols Engineering Consultants Report (June 12, 2000), the site can support the type of project envisioned by the applicant. The report also contains several specific soils-related and construction techniques that must be followed to assure compliance with the Uniform Building Code and other safety requirements Adherence to Mitigation Measures 3.6/14.0 through 16.0 contained in the Eastern Dublin ErR will also serve to reduce potential lateral spreading and related soil hazards impacts to proposed structures. e) Have soils incapable of supporting on-site septic tanks if sewers are not available? NI. The project developer has indicated that school facilities constructed on the site would be connected to a sanitary sewer provided by Dublin San Ramon Services District. Therefore, no impact is anticipated with regard to septic tanks. City of Dubltn Initial Study/Quarry Lane School PA 99-064 Page 35 July 2000 IDS ~ ~3:3 VII. Hazards and Hazardous Materials Environmental Setting The site is partially vacant and containsPha.Se One of the Quarry Lane School (currently under construction) and a single family residence and several nursery buildings on the Kobold property south of the school. The previous use of the site was likely for farming and/or grazing. Pro,ect Impacts and Mitigation Measures a-c) Create a significant hazard through transport of hazardous materials or release or emission of hazardous materials? NI. The proposed use of the site would include additiOIial phases of the Quarry Lane School and continued use ofthe landscape contracting business to the south. Neither site would include use or transport of hazardous material so there would be no impact with regard to use orrelease of hazardous materials. d) Is the site listed as a hazardous materials site? NI. The project site is not listed as a hazardous materials site, so there would be no impacts in this regard. e,f) Is the site located within an airport land use plan of a public airport or private airstrip? NI. The site is located northwesterly of the Livermore Municipal Airport but outside of any safety or referral ~zone for this airport. No impacts are therefore anticipated regarding airport safety issues. g) Interference with an emergency evacuation plan? NT. Adequate emergency access will be provided viuproposed driveways onto Tassajara Road. On-site access will be reviewed during the Site Development Review process. Due to the provision of existing and planned adequate access, there would be no impact with regard to emergency evacuation plans. h) Expose people and structures to a significant risk of loss, injury or death involving wildlandfires or where residences are intermixed with wildlands?.LS ~ The proj ect site lies adj acent to existing vacant grasslands which is subject to grassland fires during the dry portions of the year. However, the long- term plan for the area is for urbanization. Development of the project site and surrounding area would include adding new water lines for frrefighting purposes as well as new fire stations and personnel in the nearby area. Less-than-significant impacts are therefore anticipated VIII. Hydrology and Water Quality Environmental Setting The project site is yvithin the Alameda Creek watershed. Tassajara Creek, to which the project site and the uplands of the Amador Valley drains, is one of the major tributaries of Alameda Creek, draining approximately 27 square miles. StoJ;111water runoff for the project site drains directly into a small unnamed natural defined drainage, which then drains west into Tassajara Creek, then south to Alameda Creek in Sunol and fmally to San Francisco Bay. . The school property itself contains no wetlands or riparian features, although an unnamed tributary of Tassajara Creek is located in the southerly portion. of the Kobold property irrimediately to the south of the school. No major storm drain lines serve the site and it is not located within a 1 DO-year flood hazard area as defined by the Federal Emergency Management Agency. A number of mitigation measures have been included in the County EIR to deal hydrology and drainage impacts. These are summarized below: City of Dublm Page 36 Initial Study/Quarry Lane School July 2000 P A 99-064 ' /b &, cI ~3:!J · Reducing the amount of stormwater runoff from the site through appropriate grading techniques; · Constructing planned improvements during the dry season to minimize water borne erosion; · Replanting the site as soon as possible after grading and construction; · Limiting the amount of grading by appropriate staking; · Preparing a Stormwater Pollution Prevention Plan; · Verifying the size and location of existing storm drain features; · Property owner participation in County-funded programs to improve local drainage near the site. Proiect Impacts and Mitigation Measures a) Violate any water quality standards or waste discharge requirements? LSIM. Construction of improvements anticipated as part ofthe school project would necessitate additional grading and overcovering of the soil in order to construct building pads, recreational play fields, parking lots and driveways and similar features. The amount of grading is not known at this time, however, proposed grading is anticipated to increase the possibility of soil erosion into creeks and other bodies of water, on and off the project site. This could be a potentially significant impact. Mitigation Measure 6 will ensure that potential water quality impacts are reduced to a less-than-significant level. Mitigation Measure 6: The project developer shall prepare a Stormwater Pollution Prevention Plan (SWPPP), listing Best Management Practices to reduce construction and post-construction activities to a less than significant level. Measures may include, but shall not be limited to revegetation of graded areas, silt fencing and other measures. The SWPPP shall conform to standards adopted by the Regional Water Quality Control Board and City of Dublin and shall be approved by the City of Dublin Public Works Department prior to issuance of grading permits. Specific development projects containing five acres or more are also required to obtain a Notice of'Intent from the State Water Resources Control Board prior to commencement of grading. b) Substantially deplete groundwater recharge areas or lowering of water table? LS. Although the currently-vacant site would be converted to an urban use, this impact has been addressed in the Eastern Dublin EIR (Impact 3.5/2) and Mitigation Measures 3.5/49.0 and 50.0 adopted-as part of the EIR, so groundwater impacts would be reduced to a less -than-significant level and no further analysis is required. ,c) Substantially alter drainage patterns, including streambed courses such that substantial siltation or erosion would occur? LS/M. The Eastern Dublin Specific Plan ErR acknowledges that implementation of the Eastern Dublin Specific Plan would change existing natural drainage patterns on individual sites. In this instance, proposed changes would include grading and re-contouring much of the site and filling surface drainage swales with underground pipes and culverts to accommodate storm water runoff. The overall direction of storm water flow in a southwesterly direction and the direction is not anticipated to significantly change. The amount of increased stormwater runoff from the site is not known. To ensure that additional quantities and peak flows from the site would be consistent with storm drain master plans for East Dublin and that surrounding propertIes wou!d not be affected by stormwater runoff from the site, the following mitigation measure shall be adhered to: City or Dublin Initial Study/Quarry Lane School P A 99-064 , Page 37 July 2000 /t) '1 ~ ;;33 Mitigation Measure 7: Prior to issuance of a grading permit by the City of Dublin, the project developer's civil engineer shall submit written documentation to the Dublin Public Works Department that (a) anticipated stormwater runoff from the site will be consistent with master storm drain plans. If, in fact, anticipated stonnwater flows exceed any master plan assumptions, the project developer shall make arrangements satisfactory to the Dublin Director of Public Works that storm water flows can be safely accommodated. (b) Stormwater runoff from the site will not adversely impact the property to the south. Adherence to Mitigation Measure 7 would reduce potential erosion and drainage impacts to a less- than-significant level. d) Substantially alter drainage patterns or result injlooding, either on or offtheproject site? LS. Approval of the proposed project and construction of additional phases of the school would not significantly change drainage patterns within the site area. Existing surface drainage flows would be slightly altered due to anticipated site grading. Drainage would likely be routed through newly , constructed underground pipes, culverts and similar facilities. It is anticipated that on-site storm drain improvements would be constructed to connect with existing and planned drainage improvements within the Eastern Dublin area. This would be considered a less-than-significant impact. Similarly, the site lies above the I DO-year flood elevation. e) Create storm water runoff that would exceed the capacity of drainage systems or add substantial amounts of polluted runofJ? LS. Construction of on-site improvements is anticipated to lead to greater quantities of storm water runoff. Adherence to Mitigation Measure 7 would reduce this , impactto a less-than-significant level. f) Substantially degrade water quality? LSIM. Refer to the analysis and mitigation measure under "a," above. g) Place housing within a laO-year jlood hazard area as mapped by a Flood Insurance Rate Map? NI. The proposed project does not include a housing component, ~o there would be no impacts with regard to placing housing within a 1 OO-'year flood plain: h, i) Place within a lOO-year jlood hazard boundary structures that impeded or redirectjloodjlow, . . including dam failures? LS. The proposed project would not place structures withiri a I DO-year flood' hazard area, since the project includes proposed school construction. Since the project would be consistent with the Eastern Dublin Master Drainage Plan, there would be less-than-significant impacts regarding redirection of flood flows. j) Result in inundation 'by seiche, tsunami or mudjlows? NI. The site is not located near a major body of water that could result in a seiche. The risk of potential mudflow is considered low since no historic landslides or mudflows have been identified on the site (see Figure 3.6-c of the Eastem Dublin ErR).

Land Use and Planning Environmental Setting The project site is site is currently within the unincorporated portion of Alameda County and construction of Phase I improvements for the school are proceeding under County jurisdiction. " No development is currently proposed for the Kobold property, although this property is proposed for annexation to the City of Dublin and DSRSD. The site also lies within the City of Dublin sphere of influence and is also within Eastern Dublin Specific Plan/General Plan area. The property owner of the school site has requested annexation to the City of Dublin and Dublin San Ramon Services District to receive a higher range and level of urban services than is presently available in the unincorporated County area. Refer to the Project Description for a discussion of both the project site setting, existing uses on the site and requested land use entitlements by the'project proponent. Proiect Impacts and Mitigation Measures a) PhySically divide an established community? NI. The project is located within the Eastern Dublin Specific Plan area andhas been planned for urban uses since the original adoption of the Eastern Dublin Specific Plan/General Plan in 1994. Therefore there would be no disruption of any established community; b) Conflict with any applicable land use plan, policy or regulation? NI. The proposed project would be consistent with goals and policies contained in the Eastern Dublin Specific Plan/ General Plan. No changes are being proposed to the Specific Plan or General Plan. Eastern Dublin Scenic Corridor Goals and Standards, which serve to implement the Eastern Dublin Specific Plan, would also be complied with. c) Conflict with a habitat cOnservation plan or natural community conservation plan? NI. No such plan has been adopted within the Eastern Dublin Specific Plan/General Plan area. There would , therefore be no impact to a habitat conservation plan or natural community conservation plan for the , proposed project., . ' X. Mineral Resources Environmental Setting The site contains no known mineral resources. Proiect Impacts and Mitigation Measures a, b) Result in the loss of availability of regionally or locally significant mineral resources? NI. The Eastern Dublin EIR does not indicate that significant deposits of minerals exist on the site, so no impacts would occur. XI. Noise Environmental Setting Major sources of noise on and adjacent to the project site include distant noise generated by vehicles passing Eastern Dublin planning area on 1-580, traffic,sources on Tassajara Road and from aircraft ' flyovers. City of Dublm Page 39, Initial Study/Quarry Lane School July 2000 P A 99-064 ' /6<f ~ ~33 Based on Figure 3.10 B contained in the Eastern Dublin EIR, the western portion of the project site would be subject to significant long-term noise exposure, defmed as 60 decibels CNEL for exterior noise for residential land uses.. A number of mitigation measures have been included in the County EIR to deal with noise impacts during construction. These include: · Include noise generation requirements and limitations in contractor specifications; · Placement of high noise generating equipment toward the southeast end of the school site and limit placement of noisy equipment near residences. Proiect Impacts and Mitigation Measures' a) Would the project expose persons or generation ofnoise levels in excess of standards established by the General Plan or other applicable standard: LS. Construction of the proposed development project would result in incremental increases in long-term noise related to additional vehicular traffic related to the project, noise associated with playing children and short-term related to project construction. The Alameda County EIR has determined minimal and less-than significant impacts caused by vehicular traffic or schQol activities. Noise related to exterior school operations would primarily involve children using the recreational play fields towards the center and rear of the school site. Surrounded uses would be largely shielded by new buildings and noise levels would only occur during the middle of p.ay, when school is in session. Mitigation Measures 3.10/4.0 and 5.0 contained in the Eastern Dublin EIR will control short-term construction noise. These measures r~quire the project developer to prepare a ConstructIon Noise Mitigation Plan and to comply with the City1s Noise Management Ordinance. b) Exposure of people to excessive groundborne vibration or groundborne noise levels? LS. Approval of the project would not result in long-term increases in groundborne vibration, since a private school use would be constructed. Short-term vibration that may result from, construction would be controlled through adherence to Eastern Dublin Specific Plan Mitigation Measures 3.10/4.0 and 5.0. Therefore, this impact would be considered less-than-significant. c) Substantial increases in permanent in ambient noise levels? LS. Refer to item "a;lI above. d) Substantial temporary or periodic increase in ambient noise levels in the project vicinity above, levels without the project? LS. Refer to item "a,lI above. e, f) For a project located within an airport land use plan, would the project expose people to excessive noise levels? NT. The project site would not be affected by Livermore Municipal Airport due to the fact that the airport is located approximately two miles southeasterly of the project. No impacts are therefore anticipated. , City of Dublin Initial Study/Quarry, Lane School PA 99-064 . Page 40 July 2000 j/O'11 ~33 XII. Population and Housing Environmental Setting Recent information regarding population and housing in Dublin has been published in Projections '98, published by the Association of Bay Area Governments (ABAG). According to ABAG, Dublin's population (including the sphere of influence) was 26,300 in 1995 and is projected to be 33,300 in 2000. By way of comparison, the State Department of Finance has determined that Dublin's population was 28,707 as of January 1, 1999. The adopted Eastern Dublin Specific Plan/General Plan anticipates an ultimate population of 12,458 dwelling units in the Eastern Dublin planning area at full buildout of all land uses within the planning' area. The Specific Plan/General Plan also calls for a maximum of 9,737,000 square feet of commercial, office and industrial uses at full buildout of the Plan. Proiect Impacts and Mitigation Measures a) Induce substantial population growth in an area, either directly or indirectly? NI. Approval of the proposed project is consistent with the existing, approved Eastern Dublin Specific Plan/General Plan. Potential impacts related to growth inducement have been addressed in the Eastern Dublin Specific Plan EIR There would therefore be no impact associated with growth inducement. b,c) Would the project displace substantial numbers of existing housing units or people? NI.The site is occupied by Phase I of the Quarry Lane School, presently under construction. A single family has been constructed on the Kobold property immediately to the south, however, there is no plan to remove this house as part of the project. Implementation of the proposed project would therefore displace neither housing units or people. No impacts are therefore anticipated in regard to population displacement. XIII. Public Services Environmental Setting · Fire Protection. Fire protection services are handled by the Alameda County Fire Department. · Police Protection: Police and security protection is provided by Alameda County Sheriff Department. · Schools. The Dublin Unified School District (DUSD) provides educational services to the City of Dublin. · Maintenance. Maintenance of streets, roads and other governmental facilities are the responsibility of Alameda County Public Works Department. · Solid Waste Service: Private service. The Alameda County EIR identified the following mitigation measures with regard to public service impacts: · Appointment of on-site safety inspector specifically for flammable materials; City of Dublin Initial Study/Quarry Lane School PA99-064 Page 41 July 2000 I / / at ;<33 · Appropriate refueling and maintenance of construction equipment; · Construction of on-site water facilities, including building sprinklers, fire hydrants and other measures identified by the Fire Department; Environmental Impacts and Mitigation Measures a) Fire protection? LS. Construction of the proposed project would increase demand for fire and , emergency services by increasing the amount of permanent daytime population on the site. This impact was previously addressed in the Eastern Dublin EIR. Features which would be incorporated into the project as part of existing City ordinances and development requirements ~d to assist in reducing impacts would include inst:;tllation of on-site fire protection measures such as fire sprinklers, installation of new fire hydrants and meeting minimum fire flow requirements contained in the Uniform Building Code and Unif<?rm Fire Code. The project developer must also adhere to Mitigation Measures 3.4/6.0-13.0 contained in the Eastern Dublin EIR. These mitigation measures relate to funding new fire facilities in eastern Dublin, ensuring adequate water supplies and pressure for fire suppression, and minimizing wildland fire hazards. With adherence to previously adopted mitigation measures and normal City requirements, impacts related to fire protection would be reduced to a less-than-significant level. b) Police protection? LS. Incremental increases in the demand for police service could be expected should the project be approved and future developments constructed. Impacts would generally include increases in calls for service. This increase in calls for service would be offset through adherence to City of Dublin safety requirements from the Police Department, including the non- residential security ordinance. The project developer would also be required to adhere to Mitigation Measures 3.4/1.0-5.0 set forth in Eastern Dublin EIR. These measures, deal with establishing funding mechanisms for additional police personnel and facilities and require the inclusion of security provisions into individual development projects. With adherence to previously adopted mitigation me~sures and normal City requirements, including preparation of a Master Security Plan, impacts related to police protection would be reduced to a less-than-significant level. c) Schools? NL The proposed project involves the development of a private schooL Since this is a non-residential land use and would provide for classroom space in addition to educational facilities maintained by the Du1?lin Unified School District, no impacts are anticipated with regard to impacts to local schools. d), Maintenance of public facilities, including roads? LS. Approval of the project and construction of additional phases of the private school would incrementally increase the long-term maintenance demand for roads and other public facilities. However, such additional maintenance demands will be offset by additional City fees and property tGL,{ revenues accruing to the City of Dublin. Less-than- significant impacts are anticipated and no mitigation measures are needed. e) Solid waste generation? LS. Approval of the project and construction of additional phases of the Quarry Lane School would incrementally increase generation of solid waste. The Eastern Dublin EIR requires adherence to Mitigation Measures 3.4/37.0-40.0. These measures require the preparation of a solid waste management plan and assurances that adequate solid waste landfill capacity exists prior to approval of individual development projects. City of Dublin Initial Study/Quarry Lane School PA 99-064 Page 42 July 2000 / / A bf5 ~ 33 XIV. Recreation Environmental Setting There are no parks or other recreational facilities on the project site. Proiect Impacts and Mitig:ation Measures a) Would the project increase the use of existing neighborhood or regional parks? NI. The proposed project would not result in new residences being constructed within the Eastern Dublin area Therefore, no impact would result to neighborhood or regional park facilities. b) Does the project include recreationalfacUities or require the construction of recreational facilities? NL The proposed project does not include residential development, so there would be no Impact on recreational facilities or require the construction of new recreational facilities. XV. Transportation/Traffic [This section is based on a traffic analysis for Quarry Lane School prepared by Abrams Associates, Transportation Consultants, July, 2000. The full text ofthe traffic analysis is on file in the City of Dublin Public Works Department.] Environmental Setting Existing Transportation Network The project site is served by a number of regional freeways and sub-regional arterial and collector roadways; including: Tassajara Road is a two-lane rural road connecting Santa Rita Road at 1-580 to the south and continues north to the Town ofDanville. North of Contra Costa County line, it is named Cameo Tassajara and is used primarily for local traffic in the Tassajara Valley, with- some through traffic. ,The average daily traffic volume on Tassajara Road is approximately 16,800 vehicles south of Dublin Boulevard, 9,900 vehicles per day between Dublin Boulevard and Gleason Drive and 7,500 vehicles per day north of Gleason Drive. This road is currently being widened to four lanes from I- 580 to North Dublin Ranch Boulevard. Dublin Boulevard is a major east-west arterial roadway in the City of Dublin. It contains four lanes largely fronted by retail and commercial uses west of Dougherty Road. Between Dougherty Road and Tassajara Road, Dublin Boulevard is a two-lane road with an exception between Hacienda Drive and Tassajara Creek, where it is a four-lane road. Average Daily Traffic varies from approximately 29,300 vehicles east of San Ramon Road to 5,300 vehicles west of Tassajara Road. Gleason Drive is an east-west two-lane road parallel to and north of Dublin Boulevard. It serves the Santa Rita Rehabilitation Center, Federal Correctional Institute and existing developments along Gleason Drive. Gleason Drive connects Tassajara Road with Arnold Road and carries between 5,100 vehicles per day (west ofTassajara Road) to approximately 1,000 vehicles per day (west of Hacienda Drive). Portions of Gleason Drive are being widened to four lanes. Pimlico Drive is a two-way, two-lane roadway providing access to commercial and residential areas east of Santa Rita Road and south ofI-580. City of Dublin Initial Study/Quarry Lane School P A 99-064 Page 43 July 2000 //:3 ~ ~35 Existing Intersection Operations The traffic analysis prepared by Abrams Associates found that existing intersections near the proj ect site currently .operate at acceptable levels of service, defined by the City of Dublin as Level of Service "C" or better. Intersections investigated include: · Santa Rita Road/I-580 EB Ramps/Pimlico Dr. · TassajaraRd./I-580 WB Ramps · Tassajara Rd./Dublin Blvd. · Tassajara Rd./Gleason Dr. · ,Tassajara Rd./Project Driveway Previous Trip Generation on the School Site The school site has previously been used for the Villa Tassajara, a 9,500 square foot building used for weddings, social gatherings, training seminars and similar gatherings. Based on maximum use of the structure for weddings, the traffic report estimates that up to 600 vehicles per day traveled on Tassajara Road from this use. The Villa Tassajara building has since ceased being used for social functions and has been incorporated into the Quarry Lane' School as an administration building. Public Transit WHEELS operates Route 5 along Santa Rita Road and Pimlico Drive south of 1-580. Future Baseline Conditions To implement the transportation and circulation aspects of the Eastern Dublin Specific Plan/General Plan, the City of Dublin has undertaken a comprehensive program of transportation improvements in the ' community. The purpose of this program is to accommodate anticipated traffic from the Eastern Dublin area. Overall, the program includes upgrades to 1-580 freeway intersections, construction of new roads and improvements to existing roads. The program is primarily funded by fees levied on new development in Eastern Dublin and it is anticipated that the project sponsor will pay their required fees to the City as well.' ' , Future Baseline Intersection Operations The traffic impact analysis for this proposed project also analyzed the future baseline intersection operations with existing traffic, traffic from approved but not yet built or occupied development and traffic from other pending developments in the area. The traffic analysis included various mitigation measures which would be the responsibility of these other developments and which would be consistent with the City's Traffic Improvement Program, described above. With this future development in the Eastern Dublin area and appropriate traffic improvements, the traffic analysis found that the operation of the majority of study intersections could be maintained at LOS liD" or better. The TassajaraRoad/Project Driveway intersection would operate at Level of Service F during the peak hour morning conditions. A number of mitigation measures have been included in the County EIR to deal with traffic and circulation impacts. These are summarized below: ' · Dedication of right-of-way along the Tassajara Road frontage; · Construction of a southbound left-turn lane into the site from Tassajara Road if widening of Tassajara Road is not completed prior to opening of Phase II of the school; Payment of fees to fund traffic signals; . Participation in placing traffic safety signs along Tassajara Road to warn of a school zone; CIty of Dublm Initial Study/Quarry Lane School P A 99-064 Page 44 July 2000 ------------- II t( ~ ~ 'j!J · Construction of a six-foot high fence along Tassajara Road to preclude site access except at approved locations · Adoption of a Transportation Demand Management Program (TDM) to reduce number of single occupant vehicle trips generated by the school; · If Tassajara Road is not widened to at least four lanes prior to Phase III, the developer shall delay opening of Phase III until such improvements are made, or the project developer shall construct missing improvements · Preparation of a contingency parking program for special events at the school; Project Impacts and Mitigation Measures a) Cause an increase in traffic which is substantial to existing traffic load and street capacity? L8/M. The traffic analysis, which analyzed the impacts of full construction of the Quarry Lane School but not any future development on the Kobold site, concludes that implementation of the proposed project would have a potentially significant impact with regard to anticipated traffic at project entrance driveway and Tassajara Road. The proposed project entrance on Tassajara Road will require signalization to allow for safe left turn movements to and from the site. The traffic analysis included consideration of existing traffic on nearby roadways, traffic from projects that have been approved but not yet constructed and traffic from the proposed project. School trip generation rates from other private schools in the area were used for the analysis. Trips generated from the school were then distributed to nearby streets and roads. With the mitigation measure listed below, impacts tolocal streets and nearby intersections would be reduced to a less-than-significant level with regard to traffic and transportation. With the traffic improvements being installed in the Eastern Dublin area and mitigation measures associated with future approved and pending developments, all study intersections near the site, with the exception of Tassajara Road and the project driveway, would operate at satisfactory LOS "DIt or better conditions. Mitigation .Measure 8: The project developer shall install a traffic signal at the intersection of the project driveway and Tassajara Road. The traffic signal shall be in place at the time Phase 2 of the school opens for operation. b) Exceed, either individually or cumulatively, a LOS standard established by the County CMAfor , designated roads)? NI. Based on the information contained in the traffic analysis, all nearby intersections can be mitigated to Level of Service D or better, which exceeds the minimum Level of Service E established by the Alameda County Congestion Management Agency. Impacts to CMA- designated facilities would therefore be less-than-significant. c) Change in. a change of air traffic patterns? NI. The proposed project would have no impact on air traffic patterns, since it involves a private school development. d) Substantially increase hazards due to a designfeature or incompatible use? LS/M. The project traffic report notes that school project on the site could be expected to cause potentially significant traffic safety impacts, specifically, vehicular movements on site from parents dropping off children at the start of the morning classes and the possibility that parents could stop their vehicle in front of the school on Tassajara Road to drop off or pick up school children. The following mitigation measure is proposed to reduce this potential impact to a less-than-significant level: CIty of DUblin Initial Study/Quarry Lane School P A 99-064 Page 45 July 2000 J/5 15 ;;,3-5 Mitigation Measure 9a: The Quarry Lane School shall stagger the opening and closing times of the school day for the various parts of the school. The proposed hours are: . Elementary School: Open at 8:30 a.m.; close at 3:30 p.m. . Middle School: Open at 8:00 a.m.; close at 3:00 p.m. . High School: Open at 7:30 a.m.;c1ose at 2:30 p.m. These hours may be adjusted to optimize school traffic circulation. Mitigation Measure 9b: The Quarry Lane School project shall include a fence along the Tassajara Road frontage to preclude parents from dropping off students in other than approved on-site locations. Appropriate signs shall be installed in front of the school prohibiting parking or stopping in front of the school. e) Result in inadequate emergency access?LS. The current need for emergency access is low, since phase one of the school is under construction. Completion of phase one and construction of additional phases of the school would increase the need for emergency vehicle access to the site. Since the proposed site development plan indicates that the driveway on Tassajara Road currently meets or will meet minimum City design requirements potentialimpacts relating to inadequate emergency access would be less-than-significant.. The site plan for the project is also being reviewed by theAlameda County Fire Department and Dublin Police Services to ensure that on-site circulation standards, including minimum turning radii and vehicle stacking, are met. f) Inadequate parking capacity? LSIM. Parking for the proposed school would comply with the minimum number of on-site parking spaces required by the City's parking ordinance. Based on the proposed Phase 1. and 2 program for Quarry Lane School, 165 parking spaces are required. The ' proposed site plan indicates that 166 parking spaces would be provided to serve the school. The site plan as proposed assumes a new road alignment for Tassajara.Road. This proposed alignment enables the property to provide parking in accordance with the ordinance. In the event this alignment should be altered the following mitigation measure will ensure that any impacts to parking are reduced to a less-than-significant level. Mitiga.tion Measure 10: In the event thatthe proposed road alignment for Tassajara Road is altered, the applicant shall demonstrate that the site is adequately parked in compliance with the City's parking regulations prior to the issuance of a site development review permit. g) Hazards or barriers for pedestrians or bicyclists? NI. The proposed school development would include on-site bicycle parking to accommodate students and staff who choose to ride. The widening and improvement of Tassajara Road will provide for sidewalks on one or both sides of the road where none currently exist. No impacts to pedestrian or bicycle access is therefore anticipated. XVI. Utilities and Service Systems Environmental Setting The project site is served by the following service providers: · Sewage treatment and local water supply: Private well and septic system. CIty of Dublin Initial Study/Quarry Lane School P A 99-064 Page 46 July 2000 II~ ~ ;'33 · Regional water supply and distribution: Alameda County Flood Control and Water Conservation District, Zone 7 · Storm drainage: Sheet flow Environmental Impacts and Mitigation Measures a) Exceed wastewater treatment requirements of the RWQCB? LS. The regional wastewater treatment plant is currently operating in compliance with local, state and federal water quality standards. Approval of the project and annexation to the City of Dublin and DSRSD would increase wastewater flows to the plant, but would not cause the plant to exceed such standards. Mitigation Measures 3.5/1.0 through 22.0 contained in the Eastern Dublin EIR deal with wastewater treatment collection, treatment and disposal. Adherence to these mitigation measures will ensure that potential wastewater impacts of the project would be less-than-significance. b) Require new water or wastewater treatment facilities or expansion of existing facilities? LS. Approval of the project and annexation to the City of Dublin and DSRSD would require the extension of waster and sewer lines to serve the school site. Such extensions have been planned as part of the East Dublin Specific Plan/General Plan and have been analyzed in the Eastern Dublin EIR. Less~than-significant impacts would therefore result. The project developer will also be required to conform with Mitigation Measures 2.5/24.0 through 43.0 contained in the Eastern Dublin EIR regarding water service c) Require new storm drainage facilities? LS/M. Approval of the project and annexation to the City of Dublin would require additional on-site drainage facilities. The project developer has indicated that new on-site drainage facilities would be built as part of project construction. Since the amount of increased stormwater runoff is not known at this time, which could be significant, adherence to Mitigation Measure 7 would ensure ,that less-than~significant impacts would result. The project developer will also be required to adhere to Mitigation Measures 3.5/44.0 through 52.0 contained in the Eastern Dublin EIR regarding drainage. Also refer to Mitigation Measure 6 of this document. d) Are sufficient water supplies available? LS. Approval of the proposed project under the auspices of the Specific Plan/General Plan Amendment would result in an increased demand for water for domestic and irrigation purposes. This amount of increased water demand could be accommodated by DSRSD and Zone 7 facilities and long-term supplies. The project developer would be required to provide any local extensions and connections to nearby facilities. This conclusion is based on information contained in the Eastern Dublin EIR. Less-than-significant impacts would therefore result. e) Adequate wastewater capacity to serve the proposed project? LS. Approval of the proposed and annexation to the City of Dublin and DSRSD would increase the demand for wastewater treatment over present conditions. Presently, the site is served by a private septic system and there is no demand for wastewater treatment service. Based on information contained in the Eastern Dublin EIR, DSRSD has indicated that the local wastewater treatment plant has adequate capacity to serve the proposed project. Less-than-significant impacts are therefore anticipated with regard to wastewater treatment. e, f) Solid waste disposal? LS. Construction of proposed school under the auspices of the EasternDublin Specific Plan and General Plan would incrementally'increase generation of solid waste. Over the long term, the amount of solid waste reaching landfill would decrease as statewide regulations mandating increased recycling take effect. Information contained in the Eastern Dublin EIR City of Dublm Page 47 Initial Study/Quarry Lane School July 2000 P A 99-064 / I/) ci ~j~ indicates that the solid waste hauler can accommodate this project. Less-than-significant impacts are therefore anticipated with regard to solid waste disposal. The project developer must also adhere to Mitigation Measures 3.4/37.0 through 40.0 contained in the Eastern Dublin EIR regarding solid waste disposal. g) Comply with federal, state and local statutes and regulations related to solid waste? NI. The City of Dublin and the solid waste hauler would ensure that construction occurring on the project site would adhere to federal, state and local solid waste regulations. xv. Mandatory Findings of Significance a) Does the project have the potential to degf'ade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause afish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the number of 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? No. The preceding analysis indicates that the proposed project will not have a significant adverse impact on overall environmental quality, including biological resources or cultural resources with the implementation of mitigation measures recommended in the Initial Study. b) Does the project have impacts that are individually limited, but cumulatively considerable? (nCumulatively 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). No, although incremental increases in certain areas can be expected as a result of constructing this project, including additional traffic, air emissions, light and glare, short term noise emissions, the project site lies within an approved specific plan whose cumulative effects were previously reviewed in the Eastern Dublin EIR. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? No. No such impacts have been discovered in the course of preparing this Initial Study. .

August 2000 ATTACHMENT 9 I ~D 15' ;),3:3 Introduction This report compiles all letters received by the City of Dublin during the twenty-day Mitigated Negative Declaration public review period and includes responses to each of the comments. Summary of Comment Letters Comment letters were received by the City of Dublin from the following agencies and organizations. . Comment Letter 1: California Regional Water Quality Control Board, San Francisco Bay Region . Comment Letter 2: East Bay Regional Parks District . Comment Letter 3: Alameda County Flood Control District Zone 7 . Comment Letter 4: Michael E. Kyle, McNichols Randick O'Dea & Tooliatos, LLP Letter 1: Regional Water Quality Control Board Comment l: Comment l: Since the project would disturb more than 5 acres ofland during construction, a Notice of Intent must be filed with the State Water Resources Control Board Response: Page 37 of the Initial Study (second paragraph of Mitigation Measure 6) identifies the requirement to obtain a Notice ofIntent. Comment 2: The project could create runoff that could degrade water quality. Preparation of a Storrnwater Pollution Prevention Plan for the project is therefore recommended. Response: Mitigation Measure 6 requires the project developer to prepare a Stormwater Pollution Prevention Plan (SWPPP) for construction and post-construction activities. The mitigation measure further requires the SWPPP to be prepared to Regional Water Board standards Comment 3:The proposed development has the potential to impact wetlands and water quality on the site. Response: No wetlands have been identified on the Quarry Lane School site, the portion ofthe overall project site for which immediate development is being proposed. It appears wetlands exist on a portion of the Kobold property. There are existing uses on the site and no further development is being proposed at this time. A full analysis of wetlands will be completed if and when development is proposed on the Kobold site. Letter 2: East Bay Regional Parks District Comment 1: Under XIV, Recreation (a) , "Would the project increase use of existing neighborhood or regional parks such that physical deterioration would occur or be accelerated?" The Initial Study determined that "no impacts" would occur. Cumulative impacts on recreation facilities in the area are increasing, including the Tassajara Creek Regional Park. The East Bay Regional Parks District anticipates heavy and increased use of this facility as a result of school development, including. vandalism, increased litter and fire hazard from smoking. 2 1;1./ 0:6 ~3.3 Response: Although some amount of use of the Tassajara Creek Regional Park could occur, the students using the proposed Quarry Lane School will be provided with extensive open space and recreation facilities on the school site, including a large play field. Given that nearly all students attending the school will arrive and depart by private vehicles, and that the school property will be fenced off to discourage pedestrian traffic, actual use of the Regional Park is anticipated to be minimal. The school is separated from the Regional Park by Tassajara Road, which is planned as a major, six-lane, high speed arterial road, which will also form a barrier to Park access. If the Regional Park is to be used by students during school hours, such visits will be organized by the school with the Park District in accordance with the regulations of the Park District and supervised to minimize excessive litter, vandalism and smoking. Comment 2: There is a risk of increased trespass of Quarry Lane students onto Camp Parks military facility. Response: Development of the Quarry Lane School will result in essentially a closed campus, since there are no services provided in the area for students. Also, students will typically arrive and depart the site via private vehicles. Since Camp Parks site is located west of a major Road (Tassajara Road) and Tassajara Creek, the potential incidence of trespass onto Camp Parks property is considered low. Comment 3: Although no development is proposed for the Kobold site at this time, additional runoff and soil erosion may impactTassajara Creek and Trail. Identify any new storm drain outfalls into Tassajara Creek tributaries proposed for Phases I or II. Response: No storm drain outlets are proposed into Tassajara Creek tributaries as part of either Phase I or Phase II. On-site storm drain facilities constructed as part of the Quarry Lane School are planned to be connected to the existing storm drain facilities in Tassajara Road. Project , drainage and runoff impacts were addressed in both the Mitigated N egati ve Declaration and County ElR. The County EIR contains extensive discussion of the potential impact of future project runoff on Tassajara Creek under Impact D-3. The EIR states that there is a possibility that a future outfall may be needed. If ultimately, a new outfall is required, then the permitting scheme set forth in the County EIR would be followed. As noted in the District's letter, no changes are anticipated regarding storm drain runoff or erosion from the Kobold site, since no development is proposed at this time. Comment 4: The Initial Study states that service providers shall coordinate construction plans with biological regulatory agencies to reduce potential impacts to Tassajara Creek and associated tributaries. Extensive development on the Dublin Ranch has occurred south of the site and , cumulative impacts to the tributary need to be assessed. The Comprehensive Stream Restoration Program was designed to cover this tributary, and requires the City to enhance theTassajara Creek Corridor and establish and maintain liaisons with appropriate regulatory agencies. This could provide educational opportunities for students. Response: Mitigation measure 4 included in the Initial Study requires mitigation for any impacts associated with extending utilities along the tributary. Further discussions with the project civil engineer indicate that there will be no impacts to local creeks with utility line extensions. The proposed water line extension to serve the school would be located adjacent to the existing alignment of Tassajara Road and would therefore be located above the creek. Extension of a sewer line would be completed below the creek tributary via a process of boring and jacking. 3 /~~ qj ~j3 The school's storm drain system would be connected to the existing storm drain system located within Tassajara Road. Analysis of cumulative impacts to local creeks would therefore not be warranted. Letter 3: Alameda County Flood Control District Zone 7 Comment 1: Stormwater impacts from the site should also be evaluated as to whether it will adversely impact the flood control facility, Tassajara Creek. The project developer shall make satisfactory arrangements to the Dublin Director of Public Works and Zone 7 to ensure storm water flows can be safely accommodated. Response: Mitigation Measure 7, contained in the Initial Study, requires the project developer's civil engineer to furnish a letter to the Dublin Public Works Department that stormwater flows can be safely accommodated. This Mitigation Measure will ensure that stormwater impacts can be safely accommodated in local and regional drainage facilities. The project developer will be required by the City to provide necessary system upgrades. Comment 2: When the facility is connected to the District's sewer, the existing septic tank should be removed or decommissioned in such a manner that surface contaminants cannot reach the groundwater table. Response: This comment will be made a condition of project approval. Comment 3: If the on-site well becomes obsolete, the well must be properly sealed or destroyed per Alameda County Ordinance 73-68. Response: This comment will be made a condition of project approval. Letter 4: Michael E. Kyle, McNichols Randick O'Dea & Tooliatos, LLP Comment 1 :The Commentor believes that an Environmental Impact Report should be prepared to analyze grading and noise impacts of the Quarry Lane School Phase 2 project, as the site plan has changed to that originally considered by Alameda County in the Quarry Lane School EIR. Response: The Quarry Lane School (phase 1 and 2) project was the subject of an EIR which was certified by Alameda County Board of Supervisors in 1999. The EIR analyzed all potential impacts of the development of a private school with up to 1,200 students in 68 classrooms, located in one existing building (9, 600 square feet) and three new buildings totaling 78,000 square feet. The EIR analyzed the impacts of the full buildout of the school (phase 1 and 2). However, Alameda County only rezoned the property to allow the development of Phase 1. Because environmental review must be conducted at the earliest stage possible and for the entire project as contemplated, a conceptual layout for Phase 2 was prepared, but was not approved by the County. The original site plan for Quarry Lane School considered in the EIR placed the school buildings at the center of the site with a series of parking lots along the northern property line. The recreational facilities were located to the rear of the buildings adjacent to the site's eastern 4 /:23 15 ~3j boundary. The City participated actively in the County's CEQA review. The certified EIR considered two alternatives to the proposed project, the 'reduced grading alternative' and the 'reduced scale alternative'. The 'reduced grading alternative' is similar to the current project in that it proposed buildings of a similar size (approximately 86, 000 square feet) and location on the site. The buildings were located on the western section of the property at the lower to mid portion of the hillside, the northeastern hillside was left undisturbed. . The EIR also addressed potential impacts of the 'reduced grading alternative' including grading and noise. This EIR analysis has been supplemented with the Initial Study and Mitigated Negative Declaration prepared by the City for the current project. In addition, the project site is within the Dublin General Plan's Eastern Extended Planning Area and the Eastern Dublin Specific Plan Area, which was the subject of an Environmental Impact Report, certified by the City of Dublin in 1993. The General Plan/Specific Plan EIR is a program EIR, which analyzed the environmental issues related to the land use locations, development plans and policies contained in the EasternDublin Specific Plan. The EIR also anticipated subsequent project applications related to future development in Eastern Dublin. Mitigation measures adopted for the Specific Plan continue to apply to implementing projects such as the current project. A Mitigated Negative Declaration has been prepared based on the analysis contained in both the, County EIR and EDSP EIR. The City is satisfied that the EIR supplemented by an Initial Study, and Mitigated Negative Declaration prepared for the project (Kobold property and Quarry Lane School Phase 2 prezoning and annexation) adequately addresses and mitigates any potential impacts of the project. Once an EIR has been prepared fora project, a supplemental or subsequent EIR is only required to be prepared if 1) substantial changes are proposed in the project that will require major revisions in the EIR, 2) substantial changes occur with respect to the circumstances under which the project is being undertaken that will require major revisions in the EIR, or 3) new information of substantial importance to the project, which was not known and could not have been known at the time the EIR was certified as complete, becomes available. The certified EIR considered the 'reduced grading alternative' which is similar to the current site plan regarding the placement and size of the proposed buildings. No new information or substantial changes have been identified that would necessitate the preparation of a new EIR. Comment 2: The Commentor references an agreement that was entered into between Mr. Nielsen and Dr. Arac. The agreement was provided to the City. Response: The City has received and reviewed this agreement. This is a private agreement between two adjacent property owners. The City is not a party to this agreement and the agreement does not preclude the City from approving a different site plan for the Phase 2 development of Quarry Lane School. Comment 3: The reconfiguration of the site plan, results in both the playground and the Phase 2 building being located closer to Mr. Nielsen's house. The site plan proposes a large cement/asphalt playfield at the 480 to SOO-foot contour line Response: The original Phase 2 site plan presented to Alameda County was conceptual in nature. This site plan placed the building along the southern property line and recreational play fields towards the center ofthe site at the SOO-foot contour line. After further refinement of the site plan, it was realized that to accommodate the original location of the Phase 2 building and 5 J),r~J,3 play'area, three ten-foot high retaining walls would be required. The retaining walls would have been located along the entire hillside from the northwestern property line to the southeastern property line. The highest retaining wall would have been sited at the 520- foot contour. The construction of three tiers often-foot high retaining walls ranging from the 490-520-foot contours would have created significant visual impacts. In addition, the visual impacts of a three- story building located at the southern property line would be significant. The provision of adequate on-site parking was constrained by the presence of steep inclines and retaining walls. The site plan for the current project was designed to avoid these impacts. The proposed Phase 2 site plan locates the building (including classrooms and gymnasium) to the rear of the Phase 1 building to minimize the use of retaining walls, reduce grading and visual impacts and provide adequate on-site parking. The relocation of the Phase 2 building and play field eliminated the need for extensive retaining walls along the northern portion of the site. The building was designed to more closely fit the natural topography by stepping the building up the hillside, the northern wall of the building itself acts as a.retaining wall. The relocation of the building from the southern property line and the removal of the three-tier retaining wall system reduces visual impacts from both Tassajara Road and Mr. Nielsen's property. The relocation of the Phase 2 building also allowed for the creation of a flat playfield area at the southeastern portion of the site. Thereby, allowing the play field to be moved from the SOO-foot contour line at the center of the site (per Phase 1 and 2 site plan) to the 484-foot contour at the southeastern portion of the site. This in effect moves theplayfield area and associated activities further from (Mr. Nielsen's home. The playfield material will not consist of cement/asphalt but rather grass. The tennis court located to the immediate east of the playfield would be asphalt. The siting of the Phase 2 building will be closer to Mr..Nielsen's home, however the City believes that this is not an adverse change and will be of benefit to Mr. Nielsen over the previous Phase 2 concept. Instead of viewing the long face of a building, Mr. Nielsen will be viewing the north-end of the building partially buried into the hill and the roof of the new building, foreshortened. The roof has been designed to break-up the mass of the building and to screen the HV AC units. Comment 4: The movement of the Phase 2 building and the playground area would produce significant off-site noise impacts. Response: The County EIR for the Quarry Lane School analyzed the potential noise impacts of the project and concluded that school activities (which includes activities in the classroom and in the playfield) will not be significant. The EIR determined that surrounding uses would be largely shielded by the new buildings and topography. The EIR states that the effects of the 'reduced grading alternative' on noise would generally be the similar to those for the original project. An updated noise study has been prepared by Wilson Ihrig and Associates to evaluate the potential noise impacts as a result of the revised Phase 2 site plan. A copy of this noise study is attached as Attachment A. The City of Dublin General Plan identifies a Community Noise Environment Level (CNEL) of 60dB to be considered 'normally acceptable' for residential development The noise study evaluated the future noise environment compared to a CNEL of 60dB but also estimated potential noise levels generated by future activities on the site. The study determined that the average noise levels produced by approximately 100 children at play would be in the range of 65-70 dBA at approximately 100 feet from the center of the play area. Noise levels would be increased by approximately 5-6 dBA if 300-400 children were at play. Mr. Nielsen's home is 6 / ,). s ~),~ ~ located approximately 560 feet from the center of the playfield and will be partially shielded by the topography of the site. The study determined that average noise levels at the Nielsen residence produced by the playfield are projected to be approximately 57-63 dBA accounting for distance and ignoring shielding. In the event 300-400 students were located on the playfield at the same time, maximum noise levels could reach 73 dBA. According to the Applicant, Dr. Arac due to the segregat~d recess schedules for the elementary, middle and high school students and the limited recreational space on the site, it is unlikely that 300-400 students would be on playfield at anyone time. According to Table 2 of the Noise Study there is no projected increase above the CNEL of 60dB and therefore there is no significant impact. The study concludes that play area activities are not expected to significantly affect the average noise levels since these activities will occur for relatively short periods of time and primarily during daytime hours. The noise study also analyzed potential noise levels produced by activities within the Phase 2 building. The building will contain classrooms and a gymnasium and would be site of various school assemblies and sporting events. The gymnasium is located within the center of the building and is separated by a perimeter lobby and additional classrooms to the exterior wall to the east and north respectively. The building shell itself provides a barrier to noise travelling to the outside. Based on the worst case scenario, that is all students arid faculty are located within the gymnasium and the gymnasium doors and exterior w:indows are open, it is anticipated that the maximum noise level at the Nielsen residence would be between 48-58 dBA. According to Table 3 of the Noise Study there is no projected increase above the CNEL of 60dB and therefore there is no significant impact. Comment 5: The quantity of earth movement in the current proposal is greater than envisioned when the project was proposed to the County. The planners at the County of Alameda were sensitive to the natural configuration of the property and urged the applicant to redraw its plans to move site development generally westward and southward to avoid disturbing any more of the natural hillside than necessary. Response: The EIR prepared for the Quarry Lane School analyzed potential impacts of the original Phase 2 site plan and the 'reduced grading alternative'. However, the EIR did not include details regarding the quantity of earth movement required to accominodate the Quarry Lane School buildings and play fields. After, the applicant's design team further refined the Phase 2 site plan, it was realized that to accommodate the original location of the Phase 2 buildings and play fields, grading of the northern hillside and an extensive retaining wall system would be required. The original Phase 2 site plan contained in the EIR, indicated the placement of the buildings, but did not show final grading contours. (See also next response) Comment 6: The proposed site plan would result in a far greater cut and fill operations. Response: Under the original project plans, the applicant's engineer estimates that in order to accommodate the Phase 2 buildings along the southern property line and central recreational fields, approximately 165,000 cubic yards of dirt would have been needed to be cut. The current Phase 2 site plan before the City proposes a cut of approximately 63,294 cubic yards, a fill of approximately 24,107 cubic yards. The Initial Study incorrectly stated that 87, 401 cubic yards of dirt would be moved. The actual amount of earth to be moved is 63, 294 cubic yards which is equal to the amount of material to be cut, not the sum of the cut and fill as indicated by the 87,401 number. 7 /;,~ 06 :< 3,.S The City is satisfied that the cut and fill operations currently proposed to accommodate the Phase 2 building and play fields will retain a larger portion of the natural hillside without the need for an extensive retaining wall system. Comment 7: The Commentor objects to the conclusion that a Mitigated Negative Declaration is appropriate as the movement of 87, 401 cubic yards of earth on site will be a significanqmpact. Response: The grading impacts of the 'reduced grading alternative', a similar site plan in both the location and size of buildings to the current project was analyzed in the County EIR. To supplement this analysis, an Initial Study/Mitigated Negative Declaration was prepared to analyze potential site-specific impacts of the current proj ect. As referenced above the Initial Study incorrectly stated that 87, 401 cubic yards of dirt would be moved. The actual amount of earth to be moved is 63, 294 cubic yards which is equal to the amount of material to be cut. Therefore, the quantity of cubic yards to be moved as a result of the current Phase 2 site plan is not considered a significant impact.

The purpose of this project is to annex and prezone 13.6 acres ofland located within the Eastern Dublin Specific Plan Area. The application also includes a Planned Development Prezone! Development Plan for Phase 2 development of Quarry Lane School. The project site is located at 6363 and 6237 Tassajara Road. The proposed project includes construction of 66,600 square feet of floor area to accommodate new classrooms, a gymnasium, new recreational play fields, landscaping, and parking for 172 vehicles. 1. The proposed development would disturb more than five acres of land during construction. It must be covered under the State NPDES General Permit for Discharges of Storm Water Associated with Construction Activity (General Permit). This can be accomplished by filing a Notice of Intent with the State Water Resources Control Board, Division of Water Quality. The project sponsor must propose and implement control measures that are consistent with the General Permit and with the recommendations and policies ofthe local agency and the RWQCB. 2. This project may create runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provided ad4itional sources of polluted runoff. In addition, substantial alterations to the drainage pattern of the site may result in substantial erosion or siltation. Therefore, project impacts should be minimized by developing and implementing a Storm Water Pollution Prevention Plan (SWPPP). A SWPPP is required by the General Permit. The SWPPP should be consistent with the terms of the General Permit, the Manual of Standards for Erosion & Sedimentation Control Measures by the Association of Bay Area Governments (ABAG), policies and recommendations of the local urban runoff program (city aJ).d1or county), and the Staff Recommendations of the RWQCB.

Implementation of the SWPPP should be enforced during the construction California Environmental Protection Agency o Recycled Paper /;.. t ~ ~'j!, -2- period via appropriate options such as citations, stop work orders, or withholding occupancy permits. The Regional Board has prepared "Directions for preparing a SWPPP," which is available from the Board at (510) 622-2304. 3 . The proposed development has the potential to adversely impact wetlands and water quality on . the site. Section 404 of the Clean Water Act (covering, dredging, or filling of waters of the United States, including wetlands) sequences the order in which proposals should be approached. First, impacts to wetlands or waters of the State must be avoided to the maximum extent practicable. Second, the remaining impacts must be minimized. Finally, the remaining unavoidable adverse impacts to wetlands or waters of the Statemust be mitigated. Mitigation will be preferably in-kind and on-site, with no net destruction of habitat value. Impacts to wetlands or waters of the State must be avoided to the maximum extent practicable. Iftheproject will disturb any jurisdictional wetlands or waters of the State, Section 401 Water Quality Certification will be necessary. The Regional Board is unable to offer more spec~fic comment at this time. However, Ihave attached a copy of our General Comments, which discuss the Regional Board's area of responsibility, and which should help guide in the preparation of further CEQA documentation. Regional Board staff also encourage the lead agency to obtain a copy of "Start at the Source," a design guidance manual for stonnwater quality protection from the Bay Area Stormwater Management Agencies Association.

FAX (510) 622-2460 Gray Davis Governor General Comments The San Francisco Regional Water Quality Control Board (Regional Board or RWQCB) is charged with the protection of the Waters of the State of California in the San Francisco Bay Region, including wetlands and stormwater quality. The Regional Board is responsible for administering the regulations established by the Federal Clean Water Act. Additionally, the, California Water Code establishes broad state authority for regulation of water quality. The San Francisco Bay Basin Water Quality Control Plan (Basin Plan) explains the Regional Board's strategy for regulating water quality. The Basin Plan also describes the range of responses available to the Regional Board with ,regard to actions and proposed actions that degrade or potentially degrade the beneficial uses of the Waters of the State of California. NPDES Water quality degradation is regulated by the Federal National Pollutant Discharge Elimination System (NPDES) Program, established by the Clean Water Act, which controls and reduces pollutants to water bodies from point and nonpoint discharges. In California, the program is administered by the California Regional Water Quality Control Boards. The Regional Board issues NPDES permits for discharges to water bodies in the San Francisco Bay Area, including Municipal (area- or county-wide) Stoimwater Discharge Permits. Projects disturbing more than five acres of land during construction must be covered under the State NPDES General Permit for Discharges of Storm Water Associated with Construction Activity (General Permit). This can be accomplished by filing a Notice ofIntent with the State Water Resources Control Board, Division of Water Quality. An NO! and the General Permit can be obtained from the Board at (510) 266-230'0. The project sponsor must propose and implement control measures that are consistent with the General Permit and with the' recommendations and policies of the local agency and the RWQCB. Projects that include facilities with discharges of Storm Water Associated with Industrial Activity must be covered under the State NPDES General Permit for Discharges of Storm Water Associated with Industrial Activity. This may be accomplished by filing a Notice of Intent. The ptoject sponsor must propose control measures that are consistent with this, and with recommendations and policies of the local agency and the RWQCB. In a few cases, the project sponsor Vlay apply for (or the R WQCB may require) issuance of an individual (industry- or facility-specific) permit. The RWQCB's Urban Runoff Management Program requires Bay Area municipalities to develop and implement storm water management plans (SWMPs). The SWMPs must include a program for implementing new development and construction site storm water quality controls. ' The objective of thi~ component is to ensure that appropriate measures to control pollutants from new development are: considered during the planning phase, before construction begins; implemented during the construction phase; and maintained after construction, throughout the life of the project. California Environmental Protection Agency o Recycled Paper J 3D 0( cA33 In general, if a proposed project 'impacts wetlands or Waters of the State and the project applicant is unable todemo~strate that the project was unable to avoid adverse impacts to wetlands or Water,s of the State, water quality certification will be denied. 401 Certification may also be denied based on significant adverse impacts to wetlands or other Waters of the State. Storm Water Quality Control Storm water is the major source of fresh water to creeks and waterways. Storm water quality is affected by a variety of land uses and the pollutants generated by these activities. Development and construction activities cause both site-specific and cumulative water quality impacts. Water quality degradation may occur during construction due to discharges of sediment, chemicals> and wastes to nearby storm drains or creeks. Water quality degradation may occur after construction is complete, due to discharges of petroleum hydrocarbons, oil, grease, and metals from vehicles, pesticides and fertilizers from landscaping, and bacteria from pets and people. Runoff may be concentrated and stonn water flow increased by newlydevelop'ed impervious surfaces, which will- mobilize and' tran'sport _pollutants deposited on these surfaces to storm drains and creeks. Changes in runoff quantity or velocity may cause erosion or siltation in streams. Cumulatively, these discharges will increase pollutant loads in creeks and wetlands within the local w,atershed, and ultimately in San Francisco Bay. To assist municipalities in the Bay Area with complying with an area-wide NPDES Municipal Stonn Water Permit or to develop a Baseline Urban Runoff Program (if they are not yet a co-permittee with a Municipal Stonn Water Permit), the Regional Board distributed the Staff Recommendations for New and Redevelopment Control for Storm Water Programs (Recommendations) in April 1994. The Recommendations describe the Regional Board's expectations of municipalities in protecting storm water quality from impacts due to new and redevelopment projects, including establishing .policies and requirements to apply to development areas and projects; initiating appropriate planning, review, approval, and inspection procedures; and using best management practices, (BMPs) during construction and post-construction. . Project impacts should be minimized by developing and implementing a Storm Water Pollution Prevention Plan (SWPPP). A SWPPP is required by the State Construction Storm Water General Permit (General Permit). The SWPPP should be consistent with the terms of the General Permit, the Manual of Standards for Erosion & Sedimentation Control Measures by the Association of Bay Area Governments (ABAG),.policies and recommendations of-the local urban runoff program (city and/or county), and the Recommendations of the RWQCB. SWPPPs should also be required for projects that may have impacts, but which are not required to obtain an NPDES permit. Preparation of a SWPPP should be a condition of development. Implementation ,of the S\VPPP should be enforced during the construction period via appropriate options such as citations, stop work orders, or withholding occupancy permits. Impacts identified should be avoided and minimized by developing and implementing the types of controls listed below. Explanations of the controls are available in the Regional Board's construction Field Manual, available from Friends of the ,San Francisco Estuary at (510) 286-0924, in BASMA.A' s Start at the Source, and in the California Storm Water Besf..Management Practice Handbooks. 3 J.3/ qf ;;, 33 Chemical and Waste Management The project should minimize impacts from chemicals ,and wastes used or generated during construction. This should be done by developing and implementing a plan or set of control measures. The plan or control measures should be included in the SWPPP. The plan should' specify all control measures that will be used or which are anticipated to be used, including, but not limited to, the following: · Designate specific areas of the site, away from streams or storm drain inlets, for storage, preparation, and disposal of building materials, chemical products, and wastes. · Store stockpiled materials and wastes under a roof or plastic sheeting. . Store containers of paint, chemicals, solvents, and other hazardous materials stored in containers .under cover during rainy periods. · Berm around storage areas to prevent contact with runoff. · Cover open Dumpsters securely with plastic sheeting; a tarp, or other cover during rainy periods. · Designate specific, areas of the site, away from streams or storm drain inlets, for auto and equipment parking al1d fqr routine vehicle ~nd equipment maintenance. . · Routinely maintain all vehicles and heavy equipment to avoid leaks. · Perfonn major maintenance, repair, and vehicle and equipment washing off-site, or in designated and controlled areas on-site. · Collect used motor oil, radiator coolant or other fluids with drip pans or drop cloths. · Store and label spent fluids carefully prior to recycling or proper disposal. · Sweep up spilled dry materials (cement, mortar, fertilizers, etc.) immediatelyudo not use water to wash them away. · Clean. up liquid spills on paved or impermeable surfaces using "dry" cleanup methods (e.g., absorbent materials, cat litter, rags) and dispose of cleanup materials properly. · Clean up spills on dirt areas by digging up and properly disposing of the soil. · Keep paint removal wastes, fresh concrete, cement mortars, cleared vegetation, and demolition wastes out of gutters, streams, ,and storm drains by using proper containment and disposal. Post-Construction The project should minimize impacts from pollutants that may be generated by the project following construction, when the project is complete and occupied or in operation; These pollutants may include: sediment, bacteria, metals, solvents, oil, grease, and pesticides, all of which are typicaJly generated during the life of a residential, commercial, or industrial project after construction has ceased. This should be done by developing and implementing a plan and set of control measures. The plan or control measures should be included in the S\VPPP. The plan should specify all control measures that will be used or which are anticipated to be used, including, but not limited to, the source controls and treatment controls listed in the Recommendations. Appropriate control measures are discussed in the Recommendations, in: .

The District owns and manages the Tassajara Creek Regional Park and segment of Regional Trail withill Tassajara Creek Regional Park (approximately 23 acres) across Tassajara Road from tho Quarry Lane School. In 1998, the District commented on the Draft EIR for Phase 1, the initial phase of development for the Quany Lane School. The EIR planned for 62,575 buih.ling sq. ft. as the planned full buildout ofthe private school. The District understands that this project is seeking approval for the proposed development of two additional parcels (13.6 acres) cUlTently located within unjncOlporated Alameda County and the annexaHon ofthcse parcols to the City of Dublin. This project proposes to increase development of classroom and adminjstrative space to 66,685 sq. rt. for a total of 82,263 sq. ft vs. the original 62, 575 sq. n stated in the EIR. The project also proposes to add parking for 172 vehicles. recreational facilities, und landscaping to accommodate 950 students and 55 staff. The 3. 6 acre Robold ptt)pel'ty, located to the south of the school sHe for future development is proposed to be included in the annexation action, since it is the intervening property between existing City limits a.nd the Quarry Lane School Site. A tributary of Tass aj anl Creek forms the sOllthen1 boundary of the sUe. A PD Open Spaee designation for a narrow buffer adjacellt to the tributary on 1. 6 acres is indicated with the remaining 2. 0 acres to be zoned residential. 1. . Under XIV.

Mr. Nielsen lives at 6407 Tassajara Road, Pleasanto~ CA 94588. His property shares a common boundary with the project's northern boundary line. His home is situated on the hillside closely adjacent to the shared property line. Unfortunately, I have had the opportunity to read through the Initial Study dated July, 2000, only once. However, I am advised that today, August 7,2000, is the deadline for public comment. To avoid missing that deadline, I therefore take up the pen without the opportunity to fully review the Study and to cross reference It with the earlier studies produced in conjunction with the applicant's processing through the County of Alameda for Phase I of the project. 1. In general, my comments fall in two areas: (i) grading impacts, and (ii) noise impacts. Let me say generally that due to the changes in the project as it was originally proposed to my client, I believe that a full EIR should be done. The County's certification of the original EIR was based upon a much different project configuration than what is currently proposed. At that time, an agreement was entered into and recorded against the project parcel. The agreement addressed various use, aesthetic, , and noise concerns raised by the Nielsens. It is my understanding that Mr. Nielsen has provided the Dublin Planning Department with a copy of this agreement. The very first configuration of the property upon which the original noise evaluation was based had the playground area at the southern edge of the parcel down below the school buildings. Then, at the urging of the County, the plan was reconfigured to put the Phase IT building on the southern edge and to elevate the play field area more toward the center of the parcel. The agreement reached 2. between my client and the applicant provided that when Phase IT was implemented, the play field apparatus and cement/asphalt playground material would be removed. Unfortunately, the plan now before the City of Dublin leaves a rather large cement/asphalt playground at the 480 to 500 ft. elevation and moves the classroom building from the southern edge of the parcel to amore central 3. ~~~~~~~~ ~~~~ ~;~o:~~ ~ia~~~~~:t~~~~~:dpt~~C:~iin~f~=::, ~~e~~~~~~._; it 5000 Hopyard Road, Suite 400 Pleasanton, California 94588-3348 Telephone 925-460-3700 Fax 925-460-0969 www.mcnicholslaw.com jl:\n0179.oo 1\7000.doc City of Dublin Attn: Planning Department Mr. Eddie Peabody, Jr. Director of Community Development August 7, 2000 Page 2 )31 rt ~33 The original-and so far as I am aware only noise study ever conducted in conjunction with this 4. project - was based on the original configuration first submitted to the County. This is referenced in the Draft ErR, August 1998. The movement of the classroom building as well as the playground area to the locations proposed to the City of Dublin will inevitably produce off-site noise impacts that must be considered significant. Further, it appears upon quick analysis that the quantity of earth movement in the cUrrent proposal .is greater than envisioned when the project was proposed to the County. The planners at the County 5. of Alameda were sensitive to the natural configuration of the property and urged the applicant to re- draw its plans to move site development generally westward and southward to avoid disturbing any mave of the natural hillsides than necessary. This concern was heeded by the applicant at the County and was incorporated into the plan which was finally approved. For reference, the County approved the EIR for the full project, but only approved Phase I of the . project for build out. Phase I involved remodeling the existing structure and construction of a new, approximately 15,000 square foot classroom building. Both buildings border Tassajara Road and are situated on the western end of the parcel. My quick review suggests that with the relocation of the Phase II classroom building from the 6. southern edge of the parcel to the center of the parcel will of necessity result in a far greater amount . ,of cut and :fill operations. On behalf of my client, let me state that we strenuously object to the Initial Study conclusion that a Mitigated Negative Declaration is appropriate. The mere quantity of dirt 7. proposed to be moved (87,401 cubic yards) makes the conclusion that the site will be significantly impacted inescapable. : Thank you for your time and consideration. My clients have attempted to be "good neighbors" to the Quarry Lane School. However, with the project's scope and layout being so significantly changed, my client feels compelled to comment as the proposal to adopt a mitigated negative declaration is simply not justifiable in his eyes. Thank you for your consideration of our comments.

This assessment provides additional information with regard to the Phase n construction; the site plan has been revised and the jurisdiction now falls with the City of Dublin. (Ref. Letters dated 9 December 1997 and 3 April 1998 [nus-dated 3 April 1997]) This letter addresses three operational noise issues: the noise fronl the circulation of traffic to the parking lots, the noise from student" at play at the baseballlsoftbalJlsoccer field or the tennis court, and the noise from the Phase IT building. Existing Conditions The Quarry Lane School (QLS) site is located on Tassajara Road, and the school buildings will be located at a distance of approximately 140 to 300 ft from the road. To the north of the site, a single family residence (Nielson) lies approx.im.ately 90 ft from the property line. The Nielson ~esidence is situated 011 a hill overlooking Tassajara Road and has a clirect line of sight with the roadway to the south. On the south side of the site is the Kobold Nursery, and residen.ce located in close p!'oximity to Tassajara Road. The Nursery utilizes several heavy trucks and equipment in their operations during the day. The Kobold residence is shielded from the parking lot by the Villa Tassajara struclure and is located approximately 40 it from southern property line. Undeveloped privately owned Jand exists to the east of the school site. The terrain is hilly and some faeilitiesofthe school will be at a higher elevation than the land to the south" and at a lower elevation than the Nielson residence. ' As indicated in our 9 December 1997 letter, sources of noise include heavy trucks. tIyovers by aircraft utilizing the nearby Livermore Municipal Airport, and heavy vehicle operation at the Kobo.ld ATTACHMENT A: .

Ihrig & Assoc t3CJ crt ,). 33 WILSON, IHRIG & ASSOCIATES, INC. 2 Quarry Lane School Noise Assessment Nursery. The dominant noise source in the vicinity of the QLS site is the traffic on Tassajara Road. In 1997, the average daily traffic volume was 6400 vehicles with peak hour volumes of approximately 550 vehicles. Assessment of Future Conditions We understand that tl1e City of Dublin has approved plans for additional residential and commercial developments along Tassajara Road, some of which will extend to the vicinity of the QLS. In addition, widening of Tassajara Road to six lanes is currently underway south of the QLS site. Traffic Noise Traffic on TassajaraRoad will be the primary contributor to the future noise environment at the QLS -and adjacent areas. The estimated ADT on Tassajara Road in the vicinity of the QLS is 23,000 vehicles with 1432 vehicles during the peak hour (year 2005). which will result in an estimated noise level increase of 5 to 6 dBA (CNEL) over the ] 997 noise levels. The traffic noise increase will primarily affect the Nielson and Kobold r.esidences which are directly exposed to the roadway. This increase is consideredtobe a significant impact independent of the operation of the QLS. Based on the traffic projections provided by Abra:m...c; Associates, Phase II of the QLS will require 2577 daily tri ps, with 675 trips (in/out) occuning during the AM peak bour. It is estimated that traffic associated with the QLS will cause, at most, a noise level increase of 1 dBA in the local area which is not eoo!\idered signitlcant. Furthermore, traffic flow in and out of the school will be concentrated only during the morning peak. hour (7:30 to 8:30 AM). Table 1 presents a summary of the projected traffic noise levels during the morning peak hour.

The site plan for the school i.ndicates that play activities of the students will be concentrated in on the play field (socce.r, tennis, possibly softballJbaseball)at the east end ofthc site. Ambient noise levels at this location will be lower thanothcr areas since the terrain and school buildings will provide shielding from Tass8:iaraRoad.Based on noise measurements WIA has taken at playgrounds, average noise levels produced by approximately 100 children at play may be in the rcU1ge of 65 to 70dBA a.t approximately 100 ft from the center of the play area. Note that this ra.O.ge applies to the equivalent noise level (L~Il) averaged over the measurement period (e.g., 15 minutes). and that the noise level fluctuates over time and m.ay vary by approximately +/- 10 dBA. Maximum. nOl!'>e level!'> occurring for short time durations (i.e., le~s than 1 second) within the measurement period may therefore exceed the Lcq by approximately 10 dBA. As a worst case, the QLS play area may contain up to 300 to 400 students at any specified recess period which will result in 5 to 6 dBA higher noise levels relative to the 100 student level. Maximum noise levels may approach 80 to 85 dBA at the east property line due to activities on the play field, however no receptOTS exist at that location. At the north property line, the average noise level from the play field (approximate] y 430 ft from the center of the field) is projected to be approximately 57 to 63dBA (Lcq) accounting for distance and ignoring shielding, and maximum levels may reach 73 dBA. The Nielson residence is approximately 560 ft away from the play field and will be partially shielded by the topography of the Project site. The average noise levels at tbe Nielson residence produced at the play fIeld are projected to be approximately 57 to 63 dBA (L"'I) accounti.ng for distance and ignoring shielding, and maximum levels may reach 73 dBA. At the south property line, the average noise level from the play field (130 ft from the center of the field) is projected to. be approximately 68 to 74 dBA (Lcq) accounting for distance and ignori,ng shielding, and maximUln levels may reach 84 dBA. The Kobold residcnee is approximately 520 ft away from the play field and will he partially shielded by the topography of the Project site. The average noise levels at the Kobold residence produced at the play field are prqjeeted to be approximately 56 to 62 dBA (L~.q) accounting for distance and ignoring shielding, and maximum levels may reach 72 dBA. To estimate the average noise levels for atypical school day, we have assumed that there will be four recess periods (15 minutes duration, 2 for. elementary@400 students at play and 2 for high school@l00 students in animated discussion), 2 lunch periods (45 minutes duration, I for elementar.y@4QO students and 1 for high school@100 students), 5 gym class periods (50 minute duration, 100 students each), and 1 after-schoolteam sport (90 :minutes duration, 50 students). Table 2 summarizes the projected range of noise levels for each of these events and the estimated increase in the CNEL is indicated. With these projected levels. the playground noise will be audible to a person located outdoors at the north and south property lines and at the Kobold and Nielson residences, howevel'the ambient CNEL will not be significantly increased since the projected levels are not high enough to affect the daily average, and the playground activities will occur for relatively short periods of time during the daytime hours. .

IHRIC & ASSOCIATES, INC. 5 Quarry Lane School Noise Assessment Conclusion Based on this discussion. our analysis still indicates that the noise produced at the Quarry Lane School is not cxpected to have an adverse effect on the existing or futore noise environment at the neatest receptors. and the traffic volume increase on Tassajara Road will be a considerably greater contributor to the envir.onment. Traffic and play area activities are not expected to affcet the ambient noise levels significantly, particularly since these activities will occur for relativcly short periodc; of time and primarily during the daytime hours.

The updated noise study prepared by Wilson, 1l1rig &:;\ssooi@.~, Ino. (dated August 1~ 2000). City Sta:ff through the StaffRqott. andttiePlamdng Gomnnssion by way ofits recommendation to the City Councilt have already cone~~d that the School will not create significant noise -impacts. However. in responso to'm.~eoneemMi$ed by Mr. Nielsen (the neighbor who Uves to the north of the School) regarding the potential for nl)ise~ we would like to offer the . following additional m~. ~~,. '." L The Phase n plans locate the play field further away from Mr. Nielsenfa residence then the plans for Phase I. According to the noise study t the play field is now located approximately 560 it away from Mr. Nielsen's residence. The field has been designed smaller then a standard school play field. This substandard size precludes the use of this field for most organized athletic events and activities. . 2. The School can minitnize the use of the play field by oooniinating as many a.thlotic O''CnU and other JChool activities!! pouible in the indoor gym. The lluie geueullw by the activities that OCCl.lrin the gym will not be heard by Mr. Nielsen nor other individuals near the School. 3. Tbe arrival and departu:reofthe students will be stagpedin order to minimize the noise levels that may occur. In addition, the, SQhool will stagger the reces$ periods.

CA 94566 Subject: Quarry Lane School - Phase 11 Re-Assessment, Revised Dear Dr. Arac: This letter addresses noise issues for operation of the revised configuration of The Quarry Lane School at its future site on Tassajara Road in Dublin,' California. This assessment provides additional information with regard to the Phase II construction; the site plan has been revised and the jurisdiction now falls with the City of Dublin. (Ref. Letters dated 9 December 1997 and 3 April 1998 [mis-dated 3 April 1997]) This letter addresses three operational noise issues: the noise from the circulation of' traffic to the parking ,lots. the noise from students at play at the basebaU/softba!l/soc~er field. or the tennis court, and the noise from the Phase II building. This revised report incorporates the results of recent noise measurements of the existing noise environment and clarification of applicable impact criteria. Noise Impact Criteria The City of Dublin Noise Element, Table 4 present~ a chart of Land Use Compatibility which the City uses to evaluate new projects. An exterior noise environment of 60 CNBL, is generally acceptable. while, an exterior noise environment of 60 to 70 CNEL is considered conditionally acceptable and'may required noise mitigation for new residential projects. For new residential projects and new projects which are adjacent to residential areas, the City assesses a noise limit of 65 CNEL at the property line. The CNEL is a 24-hour average of the noise environment, weighting noise generated during the evening (7 to 10 PM) and during the nighttime (10 P:M to 7 AM) to account for the increased sensitivity of resident,,; during those hours. The City's Noise Ordinance addresses .'unreasonable" .Iloise~ with guidelines for assessing the impact of noise based on the time, duration and character.

IHRIG & ASSOCiATES, INC. 2 Quarry Lane School NQise Assessroent may be considered different in character from the existing noise environment. it is not expected to be considered "unreasonable". Existing Conditions The Quarry Lane School (QLS) site is located on Tassajara Road. and the school buildings will be located at a distance of approximately 140 to 300ft from the road. To the north of the site. a single family residence (Nielson) lies approximately 90 ft from the property line. The Nielson residence is situated on a hill overlooking Tassajara Road and has a direct line of sight with the roadway to the south. On the south side of the site is the Kobold Nursery, and residence located in close proximity to Tassajara Road. The Nursery utilizes several heavy trUcks and equipment in their operations' during the day. The Kobold residence is shielded from the parking lot by the Villa Tassajara structure and is located approximately 40 ft from southern property line. Undeveloped privately owned land e~ists to the east of the scl:1001 site. The terrain is hilly and some facilities of the school will be at a higher elevation than the land to the south, and at a lower elevation than the Nielson residence. As indicated in our 9 December 1997 letter, sources of noise include heavy trucks. flyovers by aircraft utilizing the nearby Livermore Municipal Airport. and heavy vehicle operation at the Kobold Nursery. The donrinant noise SOlII'ce in the vicinity ofthe QLS site is the traffic on Tassajara Road. In 1997. the average daily traffic volume was 6400 vehicles with peak hour volumes of approximately 550 vehicles. Figure 1 indicates the site plan and location of noise measurements. These measurements were peri'orxned from November 1 to November 3, 2000. Location 1 was located in the parking loL of ,the Quarry Lane School. Location 2 was placed on a tree to, the south of the auditorium. close to the Kobold residence? and Location 3 was placed at the north property line. close to the Nielson residence. Figures 2 through 4 indicate a summary of the hourly .q.oise levels obtained at- the roeasurement locations. CNEL ranges from 62 to 63 near Tassajara Road (Location 1) to 63 to 64 at the south property line near the Kobold residence (Location 2) to 51 to 54 at the north property line near the Nielson residence (Location 3). ,Locations 2 and 3 were located near the property line~ but we believe they are comparable to the noise enviroomenlcurrently experienced at the nearby residences: The elementary school is currently in session. and these measurements include the typical daily noise from oper~on of the elementary school, including recess and after-school play. Note that the business operations at the Kobold property and construction at the Dublin Ranch also contribute to the total noise environment. particularly the environment along the south property line, near Location 2. We expect that the noise environment along ,the southern property line (west side) are similarly affected by the Kobold business, and we expect that the existing noise levels along the south property line, closest to the. Kobold business yard, just meet or exceed the 65 CNEL limit. School starts at 8: 15 AM. with a recess'around 10 AM, lunch shifts between 11 AM and 12:35 PM and school ends at 3 PM. These activities are generally identifiable in Figures 2 through 4. We expect that the existing school activities has caused the CNEL at Location 3 to increase by less than 1..'1111_1 ...._~r,:\ClCl 1 Cl. ....<:::C'lM Tt::'1 "0<:::1 Cl .:::ci:~ 4441 TI"'o "o"TTV iiI:' 1"'0' I~I nJ PClr.:I=~OIli1",( p=qq% 11/13/00 MON 09:33 FAX 510 652 4441 W11pon,Ihr1g & Assoc. /55 crI ~3' WILSON, IHRIG & ASSOCIATES. INC. 3 Quarry Lane School Noise Assessment 1 dB. Thus. the noise measurements indicate that the existing noise environment near all residential locations falls within the acceptable range for the City ot Dublin. Assessme~t of Future Conditions We understand that the City of Dublin has approved plans for additional residential and commercial developments along Tassajara Road, some of which will e~tend to, the vicinity of the QLS (i.e., Dublin Rancb). In addition, widening of Tassajara Road to si~ lanes is cunently underway south of the QLS site. Traffic Noise Traffic on Tassajara Road will be the primary contributor to the future noise environment at the QLS and adjacent areas; The estimated ADT on Tassajara Road in the,vicinity of the QLS is 23,000 vehicles with 1432 vehicles during the peak hour (year 2005). which will result in an estimated noise level increase of 5 to 6 dBA,' (CNEL) over the 1997 noise levels. The traffic noise increase will . . primarily affect the Nielson and Kobold residences which are directly exposed to the roadway. This increase is considered to be a significant impact independent of the operation of the QLS. Based 00 the traffic projections provided by Abrams Associates, Phase II of the QLS will require 2577 daily trips, with 675 trips (inlout) occurring during the AM peak hour. It is estimated that traffic associated with the QLS will cause, at most, a noise level increase of i dBA in the local. area. which is not considered significant. Furthermore, traffic flow in and out of the school will be concenl:rated only during the morning peak hour (7:30 to 8:30 AM). Table 1 presents a summary of the projected traffic noise levels during the morning peak hour.

The QLS will ultimately enroll approximately 950 studen.ts although not all students will be a,t play in the exterior areas simultaneously.

Ambient noise levels at this location will be lower than other areas since the terrain and school buiIdip.gs will provide shielding from Tassajara Road. Based on noise measurements WIA has taken at playgrounds, average noise levels produced by approximately 100 children atplay may be in the range of 65 to 70 dBA at approximately 100 ft from the center of the play area. Note that this range applies to the equivalent noise level (~) averaged over the measurement period (e.g., 15 minutes), and that the noise level fluctuates over time and may vary by approximately +/- 10 dBA. Maximum noise levels occurring for short time durations (Le., less than 1 second) within the measurement period may therefore ex.ceed the Leq by approximately 10 dBA. As a worst case, the QLS play area may contain up to 30000 400 students at any specified recess period which will result in 5 to 6 dBA higher noise levels relative to the 100 student level. Maximum noise levels may approach 80 to 85dBA at the east property line due to activities on the play field.. however no receptors exist at that location. At the north property line, the average noise level from the play field (approximately 430 ft from the center of the field) is projected to be approximately 57 to 63 dBA (Leq) accounting for distance and ignoring shielding, and mwmumlevels may:reach 73 dBA. The Nielson residence is approximately 560 ft away from the play field and will be partially shielded by the topography of the Project site. The average Doise levels at the Nielson residence produced at the play field are projected to be approximately 57 to 63 dEA CLeq) accounting for distance and ignoring smelding. and maximum levels may reach 73 dBA. At the south property line, the average noise level from the play field (130 ft from the center of the field) is projected to be approximately 68 to 74 dBA (Lcq) accounting for distance and ignoring shielding, and maximum levels may reach 84 dBA~ The Kobold residence is approximately 520 ft away from the play field and will be partially shielded by the topography of the Project site. The average noise levels at the Kobold residence produced ,at the play field are projected to be approximately 56 to 62.dBA (Leq) accounting for distance and ignoring shielding, and maximum levels may reach 72 dBA.

With these projected levels, the playground noise will be audible to a person located outdoors at the north and south property lines and at the Kobold and Nielson residences, however the ambienL CNEL will not be significantly increased since the projected levels are not high enough to affect the daily average, and the playground activities will occur for relatively short periods of time during the daytime hours. (See below) , , ", Gymnasium The Phase II building will house the gymnasium. which will be the site of various school assemblies and sporting evcnts~ At worst case, a capacity event in the gymnasium would conTain the entire , student population and school faculty. While the Phase 1I building does have windows on the east and westfacades~ the gymnasium is separated from the exterior walls 'by a perimeter lobby. At worst case~ the gymnasium doors would be open into the hallway and the windows would. be open, allowing cheering and other noises from the gymnasium to travel to the exterior of the building. We have asswn.ed that all such events would occur before 7 PM, with a duration up to 90 minutes, and that the shielding provided by the building shell provides 10 to 20 dB noise reduction as compared to an assembly outdoors.

Shnilarly. the noise levels at the northern property line will also remain below 65 CNEL. but at the southern property line closest to the proposed play field, the CNEL will exceed 65. In this affected area, we.believe that there is no noise impact because 1) there are no residences in this area and 2) the noise environment is expected to be 65 CNEL or slightly greater from the busines,s activities generated on the Kobold property. QLS traffic . and play area activities are not expected to affect the ambient noise level,; significantly. particularly since these activilies will occur for relatively short periods of time and priIWUily during the daytime hours. The traffic volume increase on Tassajara Road due to other projects will be a considerably greater contributor to the environment than the QLS project..

This assessment has been revised to incorporate the results of the reVised noise assessment;a1so dated~7 November 2000. . We have reviewed the plan drawings (Cl) prepared by Ruggeri-Jensen"Azar & Associates; dated September 28,2000 for Alt.2 and J one 7, 2QOO for Alt. I, to determine if there will be any substantial change in the noise effected by the proposed change in field location and elevation. For Alternativel, we project tb.at there will be some shielding of playfield noise at the Nielson residence pro"ided by. tb.e 520 ft contour line. For Alternative 2. the new 520 ft contour line will also provide some shielding of noise. As the 520ft contour line for Alternative 2 is witb.inlO ft of the same contour in Alternative 1, there is no difference in noise attenuation provided. No other shielding is anticipated from the proposed topogr.aphy. The playfield location in Alternative 2 is projected to cause an increase in noise level.less than 0.5 dBA at the Kobold residence, as compared to Alternative'i. , Based on this data, compared to Alternative 1.

Traffic. Engineering. PIano /(,b ~ ;,~!; Updated Traffic and Circulation Study of the Quarry Lane School in the Dublin Area of Alameda County (Abrams Associates - July 12,2000) 1.) Executive Summary The Quarry Lane School is proposed to be built on Tassajara Road in.an . " unincorporated area of Alameda County. The purpose of this report is to provide updated traffic data, in part due to the large number of projects that have now been approved in the area. The original traffic report for this project was completed in December 1997, and Phase 1 of the school is currently under construction. This phase will accommodate 200 students and is scheduled to be opened in September of 2000. Phase 2 of the Quarry Lane School is now planned to be implemented within the next three years, which will bring the size of the school to an enrollment of 950 students. The previous traffic study considered a school with a maximum enrollment of 1,200 students, so the current project is now smaller, and will have less of a traffic impact than was evaluated in that report. However, since the time of that report, there have been additional projects proposed in this area, so the traffic data needed to be updated accordingly. It is also necessary to look more closely at the timing for the construction of an interim traffic signal at the project entrance. The findings of this report are that there would be no significant traffic impacts on the study intersections that would result from the school as it is currently proposed. This is discussed in more detail below. Beyond the construction of an interim traffic signal at the school entrance, there are no traffic capacity or safety mitigation measures that would be required as a result of this project. The proposed site plan has adequate space on-site for vehicles to queue while waiting to drop off or pick up students, and there is adequate parking for parents, students and visitors to the school. Page 2 Quarry Lane School Updated Traffic Study Abrams Associate Transportation. Traffic. Engineering. Planni /~ -1 cI ;~J; 2.) Background The proposed project would involve the development of the Quarry Lane School on Tassajara Road. The location of the project and the study area for this traffic analysis is shown on Figure 1. The school is planning a first phase with up to 200 students and a second phase that would increase the size of the school to 950 students. The site is located on the east side of Tassajara Road in unincorporated Alameda County just to the north of the City of Dublin. The site is currently occupied by a 9,600 square foot building that is used for special events such as weddings, l1}eetings and parties. There is also an existing parking lot with 90 spaces. This existing building will become the administrative offices and will also house some classrooms for the school. A project site plan has been submitted to the City and County, which shows the layout of all school buildings and play fields, as well as the location of the driveways and parking areas (See Figure 2). The plan also shows the proposed access design along Tassajara. As mentioned above, there are plans to widen Tassajara Road to a six-lane arterial in the near future (within the next five years). The Quarry Lane School will dedicate the necessary right-of-way for the future widening of Tassajara Road, and will be responsible for the cost of the frontage improvements. In this study, five intersections on Tassajara Road were analyzed to determine their future capacity conditions. The three scenarios that were studied included; 1) Existing Conditions, 2) Existing plus Approved Projects, and 3) Existing plus Approved Projects plus the Proposed Project. 3.) Existing Traffic Conditions Existing Roadway Characteristics - As shown in Figure 1, the main access to the school would occur from a driveway connection to Tassajara Road. Tassaiara Road is a two-lane rural road, which runs from 1-580 north to the Town of Danville. To the south ofPimlico Drive and 1-580, Tassajara Road turns into Santa Rita Road, a six-lane arterial that serves the east side of Pleasant on and provides access to " downtown. Dublin Boulevard is, a two-lane roadway running east-west parallel to the 1-580 Freeway and provides access to central Dublin. To the west of Dougherty Road Dublin Boulevard becomes a four-lane arterial.

'b~ Gleason Drive is a two-lane roadway that serves the Santa Rita Rehabilitation Center and a few other county facilities such as the local California Highway Patrol office and an Alameda County Corporation Yard. Pimlico Drive is a two-way two-lane roadway that provides access to corn.mercial and residential areas to the east of Tassajara Road and south ofI-580. 1-580 is a six-lane east-west freeway that is one of the main access routes for Bay Area traffic hound for 1-5, the Central Valley, and Los Angeles. 1- 580 is also the main r~)Ute used to access Oakland and San Francisco from the Livermore Valley. Intersections - Five intersections were analyzed for this study. These intersections are listed below and are also noted on Figure 1. 1. Santa Rita Road/ 1-580 EB Ramps/Pimlico Drive 2. Tassajara Road/I-580 WE Ramps 3. Tassajara RoadlDublin Boulevard 4. Tassajara Road/Gleason Drive 5. Tassajara Road/Project Driveway The project entrance is currently unsignalized hut the other four intersections have traffic signals, although the signal at Tassajara Road and Gleason Road is not yet functional. Figure 3 shows the existing lane configurations at each of the project study' intersections. Existing Traffic V oluIDes - Figure 4 shows the existing traffic volumes on the major streets in the area. The traffic count data for each of the study intersections was taken from the recent Traffic Study for the Proposed Dublin Ranch Areas F - H.l Analysis Methodology - The TRB (Transportation Research Board) Circular 212 methodology used in analyzing operations at signalized intersections is based on the utilization of intersection capacity. This methodology yields both a volume-to-capacity (V/C) ratio and Level-of-Service (LOS) ratings from A to F. For this study, the LOS for signalized intersections has been determin~d using the most recent 1995 update of the Contra Costa County Transportation Authority's CCTALOS Program (Version 2.35). The level-of-service definitions and corresponding volume to capacity ratios for signalized intersections are included in the Appendix. The unsignalizedintersections were analyzed using the methodology set forth in Chapter 10 of the Highway Capacity Manual, which is based on average total delay (seconds/vehic1e).2 The capacity of each approach is estimated as a function of the proportion of traffic on each approach, the number of lanes on each approach, and the proportion of turning movements on the opposing and conflicting approaches. With the. average total delay for each approach the levels of service for each approach and for the 1 Traffic Study of the Proposed Dublin Ranch Areas F - H, TJKM Transportation Consultants, March 21, 2000. 2 Highwav Capaciiy Manual.

There are also six levels of service, A through F, which represent conditions from best to worst. Table 1 shows the corresponding average total delay per vehicle for each LOS category from A to F for unsignalized intersections.

Page 9 Quany Lane School Updated Traffic Study Abrams Associate~ TransportatiO/.i~C qsin~n3. 9annin The existing traffic volumes are in all cases below the physical capacity of the streets, and there are only minimum delays for traffic in the area. There are no safety problems at these intersections under the existing conditions. Previous Trip Generation on the Site - The site has previously been operated by the Vista Tassajara, which is a 9,600 square foot building which is used for weddings, parties, meetings, training seminars, etc. There is also an existing parking lot on the site with 90 parking spaces. The maximum capacity of the building is approximately 240 people, and certain events do serve this number. On an annual average, it is reported that the meeting hall serves events that average about 650 people each week. During peak times of the year, the weekly average is about 1,000 people at about 10 to 12 different events. On a peak day, generally on a weekend, there would be events that serve about 300 people on the site. The trip generation for this building when used as a wedding hall can be roughly estimated based on the number of people served and the size of the parking lot. A triprate of 2.0 trips per visitor per day is estimated, which assumes that the guests themselves average 1.5 trips per day, and that the remainder, 0.5 trips per visitor per day, is the result of trips by employees, visitors and various service providers. For 1,000 people in a week, or 140 people per day, the trip generation is estimated to be 280 vehicle trips per day (vpd). On a peak day, the trip generation would be about 600 vpd. Parking - As noted, there is an existing parking lot on the site with about 90 spaces. This is expected to be of sufficient size to serve the needs of the school during Phase 1. There is no on-street parking on Tassajara Road, and there will not be in the future after it is widened. Bus Transit Service - Wheels operates Route 5 along Santa Rita Road and Pimlico Drive to the south of 1-580. The route operates on 30-minute headways during commute hours and one-hour headways at all other times. The route begins operation at 6:15 AM until the last bus leaves at 6:45 PM. There is also a shuttle bus service between the Santa Rita Rehabilitation Center and the Dublin BART Station that uses Dublin Boulevard, Tassajara Road, and Gleason Road. The shuttle operates on 15-minute headways from 6:30 to 9:00 AM and from 2:00 to 7:00 PM. Existing Quarry Lane School Site - Quarry Lane School has an operating school in Pleasanton at 3750 Boulder Street near Quarry Lane. This school has a current enrollment of 320 students and serves pre-school through 5th grade. Observations of traffic conditions have been made during the A.M. and P.M. peaks and traffic is shown to operate smoothly at all times. The most critical time is the 15 minute period just prior to the start of school in the morning when there is a lot of activity. It can be expected that similar traffic patterns will occur at the new school. Speeding Issues on Tassajara Road - The posted speed limit on Tassajara Road in the vicinity of the school is50 mph. Traffic counts conducted by Alameda Page 10 Quarry Lane School Updated Traffic Study Abrams AssociatE Transportation. Traffic. Engineering. Plan! / 75 ~ ),:!;j County show an ADT of 5,200 vehicles per day at the Contra Costa/Alameda County Line. Speed surveys taken in the vicinity of the school show that 80 percent of the vehicles are exceeding 50 mph, and the 85th percentile speed is 59 mph. During a recent three-year period (1991-1994) a review of accident records indicated that 11 accidents had occurred on this section of Tassajara Road. Ofthese, 5 involved injuries and one was a fatality. The accident rate for this 2.8 mile section is 0.69 accidents per million vehicle miles. These statistics are not unusual for rural roag.s of this type in Alameda County, and in fact, the accident rate is below average. However, with the transition of this site into school uses, and other new urban development in the area, these types of speed conditions should be monitored. ~ 4~) Impacts of Approved Projects List of Approved Projects - The following list of approved. projects has been taken from the traffic study prepared,by TJKM for the Dublin Ranch Areas A-F 1 and from the Traffic Study of the Dublin Ranch Phase I Residential Development.3 Approved projects consist of developments that are either under construction, are built but unoccupied or partially occupied, or that are not yet built but have approval of their final development plans. The approved projects in the area and their associated trip generation are shown on Table 3 on the following page. It should be noted that adding the traffic from other pending projects in the area would not change any of the conclusions about the traffic signal at the project entrance. Traffic from pending projects also would not be expected to change the conclusions about project impacts at the other four project study intersections. However, this does assume the completion of traffic improvements that are planned by the City of Dublin through their Traffic Impact Fee program. It is assumed that the traffic studies for the pending projects will updated as necessary to include the traffic from projects such as the Quarry Lane School. If the preparation of an "existing plus approved plus pending plus project" scenario is a general requirement for traffic studies in the City of Dublin then the studies for the various pending projects would include the traffic from the proposed Quarry Lane School. The original traffic study for the Quarry Lane Schoolwas submitted well before any of the traffic studies for the current pending projects so it is assumed that detailed pending and cumulative analyses are available in their respective traffic studies. If the City finds that additional data is required, then information from those reports could be incorporated into this study. 3 Traffic Study of the Proposed Dublin Ranch Phase I Residential Development, TJKM Transportation Consultants, July 29, 1998.

Plann . / ~t:. 06 ;<85 Proposed Future Transportation Improvements - This area of Dublin will undergo some major improvements to the transportation network. Tassajara Road is currently four lanes from 1-580 to Dublin Boulevard and two lanes in width from Dublin Boulevard to the north. The entire roadway will be widened to six lanes in the future. As mentioned above, a signal has recently been installed on Tassajara Road at Dublin Boulevard and also at Gleason Boulevard. Also, Hacienda Drive has been extended as a three-lane road to Gleason Road. All ofthese projects will affect the traffic patterns in the study area.

This scenario is considered to be the "Background" scenario. The results of the level-of- service analysis for the Existing plus Approved Projects Scenario are shown in Table 4 on the following page. Under this scenario, none of the study intersections are projected to operate at unacceptable levels of service. It is assumed for this scenario that Tassajara Road will continue to be a two-lane road to the north of Gleason Drive. Signal Warrant Analysis - At the intersection of Tassajara Road and Gleason Drive, it is assumed that a fully functional traffic signal would be in place under the Existing plus Approved scenario.

School Transportation Characteristics The traffic generated by the Proposed Quarry Lane School would come from teachers; staff and visitors to the school, as well as from student transportation. It is assumed that all students (pre-school through 8th grade) would be accompanied by an adult when arriving or leaving the school.

The general hours of operation for the school would be from 8:00 a.m. to 3:00 p.m. There would also be some additional activities on site that would allow parents to drop- off their children as early as 7:00 AM and pick them up as late as 6:00 PM. It is expected that about a third of the parents would use the these services to drop-off early, pick- up late, or both. PedestrianIBicycle Access - The number of students and employees walking or bicycling to this school will be very limited. There may be a couple students who live in the immediate neighborhood and are able to walk or bicycle and as the area develops this number will increase. However, for the purposes of this analysis it is assumed that all students and employees would arrive by private automobile or in carpools. School Trip Generation - The expected trip generation from the Quarry Lane school for phases 1 and 2 is shown on Table 4. Recent traffic studies prepared for other schools, including a private school in Danville, show a trip rate of about 0.80 trips per student in the AM peak and 0.63 trips per student during the school's PM peak hour. Studies of other private schools, including the Sierra School in El Cerrito, Berean Christian High School in Walnut Creek, and several schools in the Sacramento area also show similar trip rates.

For the high school portion of the school, the trip rate is estimated to be about 2.25 trips per student per day. The high school (up to 150 students) trip rate is less because, even though some students will drive themselves to the school, these would only be one-way trips while the students are parked at the school. There would also be fewer trips by parents driving to the school. Based on these calculations, there would be 374 entering vehicle trips and 301 exiting trips in the AM peak hour when the school is fully occupied. This is reasonably close to the number of trips that would be generated using the ITE trip generation rate. Abrams Assoc iate~ The afternoon traffic is more dispersed since some of the staff and students remain on-:site for after school programs and various meetings. The school afternoon peak traffic (2:30 to 3:30 PM) is less than the morning, and generates about 400 vehicle trips. During the PM commute peak hour (5:00 to 6:00 PM) the school would generate about 162 outbound vehicle trips and 129 inbound trips. Quarry Lane School now expects to use the following opening and closing times of the school day for the various parts of the school. The following lists the proposed hours: . Elementary School: Open at 8:30 a.m.; close at 3:30 p.m. . Middle School: Open at 8:00 a.m.; close at 3:00 p.m. . High School: Open at 7:30 a.m.; close at 2:30 p.m. If this program is implemented, the peak hour trip generation can be significantly reduced from that shown in Table 4. The school intends to evaluate this program, and make adjustments as needed to optimize the school traffic circulation. Trip Distribution - Traffic from the completed Quarry Lane would be distributed and assigned as shown on Figure 6. This distribution has been estimated based on land uses in the area and expected enrollment patterns at the school. The largest portion of the school traffic is expected to come from the south from 1-580. The trip distribution assumptions for the project trips are listed in Table 5. Figure 7 shows the total traffic volumes at each intersection bas{(d on the sum of existing traffic plus approved trips plus project traffic.

Auditorium and sport fields will be limited to school activities only. There are no plans for any large sporting events that will draw a significant crowd. Events such as parent's nights, back-to-school nights, etc. will be limited to certain grades so the site capacity will not be exceeded. This impact does not need to be further evaluated. 6.) Impact Analysis Capacity and Level-of-Service Analysis - As described earlier in Table 4, during the first phase with 200 students, the Quarry Lane school would generate 88 inbound tr~ps and 72 outbound trips during the AM peak hour between 8:00 AM and 9:00 AM. During the PM peak hour of traffic in the surrounding area (5:00 AM and 6:00 PM) it is estimated that the school would generate 124 inbound trips and 173 outbound trips. With the addition of Phase 2 project traffic (950 students) all project study intersections will operate at Level of Service D or better with planned roadway improvements and a traffic signal at Tassajara RoadlProject Driveway in place. The results of the level-of-service analyses are shown below in Table 6.

The level-of-service calculations for each of these intersections are included in the appendix of this report. Calculations both with and without signalization and the mitigations are also included. Parking Needs Analysis - There are no standardized parking guidelines for private schools of this type. However, the parking requirements for elementary schools are frequently based on one (1) parking space for each employee. The Quarry Lane School proposes to have 90 parking spaces during Phase 1, with 30 total employees and a maximum of 20 employees and staff parked on site at anyone time. This would meet the employee parking requirement in most parking codes. At another private school which has a 600 student enrollment, on a typical weekday there are about 35 to 40 spaces used by employees and staff, and about 20 to 30 parking spaces being used by visitors and parents. With an enrollment of950 it is expected, based on counts of parking at other schools, that there would be a maximum of about 145 parking spaces required during the school day. Figure 8 summarizes the expected parking demand for the Quarry Lane School. Table 8 Parking Demand at Quarry Lane School Estimated Parking Demand Staff Studen t Visitor Total Parking to be Parking Parking Parking Demand Provided Phase 1 - 200 20 0 30 50 90 students Phase 2 - 950 55 40 50 145 175 students Traffic Signal at the Project Entrance - As noted in the report and shown on the site plan, all access to the school will occur at a driveway that connects to Tassajara Road. A traffic signal is not warranted with the existing conditions, nor will it be warranted during the first phase of the school, when there will be up to 200 students. While this portion of Tassajara Road is presently considered as a rural area, in a few years it will certainly have urban traffic characteristics. The peak hour volume warrant (Warrant 11) for urban areas suggests that this traffic signal will be warranted when the side street (school driveway) traffic exceeds 160 vehicles per hour. Once Tassajara Road is widened to be four lanes divided, the signal would be warranted at the point when the side street traffic exceeds 200 vehicles per hour. . The traffic volumes are not likely to meet Warrant 1 (Minimum Vehicular Volume) for eight hours, even when the maximum enrollment of 950 students is reached. Based on the expected traffic volumes, a traffic signal should be constructed and be in operation by the time that the school reaches a level of about 400 students. . Page 20 Quarry Lane School Updated Traffic Study Abrams Associates Transportati7 gT:;C :;ne)g ~ ;nninl However, the precise timing when this will occur is unclear at this time. Tassajara Road is planned to be widened to a four lane divided roadway within the next few years, and the signal should certainly be constructed in conjUnction with this widening. If this widening is delayed, however, and Phase 2 of the school proceeds before the widening takes place, an interim traffic signal should be constructed at the school entrance due to safety considerations. As a part of this interim operation, a left turn lane should be constructed for southbound traffic, along with a right turn lane for northbound traffic. This signal should be in place at the time that Phase 2 opens for operation. Pedestrian and Bicycle Access - At the current time, pedestrian and bicycle access to the school is quite difficult. There are no sidewalks in the area, and Tassajara Road is not wide enough for safe bicycle travel. During the first phase or two of the . school, this condition will continue. . It is not expected that any students will walk or bike to the school. There is no residential development near the school at the present time, but this will change in the future. With the widening of Tassajara Road, it is anticipated that there will be a separate bicycle and pedestrian path on the east side of the roadway. There will be pedestrian crosswalks and pedestrian signals incorporated into the ultimate traffic signal on Tassajara Road at the school entrance. These improvements will alleviate future pedestrian and bicycle access issues. On-Site Circulation - The project site plan shows two driveways connecting to Tassajara Road. There will be no median opening to the northernmost driveway so the driveway will be limited to right turns only. A separate right turn lane on Tassajara Lane will not required at this driveway. The southernmost driveway will be signalized at the time that Phase 2 of the school development opens for operation, and will be the location for all access to the school. The outbound movement from the school will have two lanes, separately designated as right and left turn lanes. The aisle widths, parking space dimensions, and circulation features within the Quarry Lane School meet the City of Dublin standards. The internal circulation will operate safely and efficiently. The most critical movement on the school grounds will be from parents dropping off their children at the start of morning classes. It is expected that vehicles would queue up adjacent to the front of the school when dropping off and picking up children. There is enough space on-site to store a queue of up to 34 waiting vehicles, and this will be more than adequate for this school. The location of this queuing is illustrated on the attached site plan. This program will prevent vehicles from stacking out onto Tassajara Road. All traffic operations aspects of the site plan are satisfactory. The driveway to the parking lot is located at least 75 feet from Tassajara Road. Vehicles exiting from this driveway will merge with other outbound traffic on the approach to the signal. Quarry Lane School has plans to stagger the opening and closing times of the school day for the various parts of the school. The following lists the proposed hours: Page 21 Quarry Lane School Updated Traffic Study Abrams Associates Transportation. Traffic. Engineering . Plannin~ I't"b c( ~'3J . Elementary School: Open at 8:30 a.m.; close at 3:30 p.m. . Middle School: Open at 8:00 a.m.; close at 3:00 p.m. . High School: Open at 7:30 a.m.; close at 2:30 p.m. If this program is implemented, the traffic volumes will be stretched out over a longer period, and the peak hour traffic can be significantly reduced. The school intends to evaluate this program, and make adjustments as needed to optimize the school traffic circulation. 7.) Study Results and Conclusions The Quarry Lane School project would not result in any significant traffic impacts at any of the five project study intersections or on other local streets in the area. This assumes the completion of traffic improvements that are planned by the City of Dublin tHrough their Traffic Impact Fee program. There will be increased traffic and activity on Tassajara Road at the school, but this traffic can be accommodated without any special delay or traffic safety problems. Other than the construction of an interim traffic signal at the entrance, there are no traffic mitigation measures that are required by this project. As is shown in this study, however, there are certain traffic safety and operational items that should be considered on Tassajara Road. Currently, Alameda County is planning to widen Tassajara Road to a six-lane arterial in the near future. The Quarry Lane School will dedicate the necessary right-of-way for the future widening ofTassajara . Road, and will contribute to the cost of the frontage improvements. Mitigation measures to address the issue of high speeds on Tassajara Road have been reviewed. The school has made it clear that at no time will any parents be permitted to stop on TassajaraRoad to pi.ckup or drop-off children. The Caltrans Traffic Manual and Section 22352 of the California Vehicle Code both state that school zone signing is not required if there are no school pedestrians using the highway and the school grounds are separated from the highway by a fence, gate or other physical barrier: Since a 25 mph school zone on this section of Tassajara Road would be undesirable, we have recommended that the school have a fence installed along the Tassajara Road frontage. A southbound left turn lane on Tassajara Road will be required along with the interim traffic signal at the school entrance at the time that Phase 2 opens for operation. A northbound right-turn lane should also be constructed at the school entrance. It is recommended that the left turn lane be put in place before the school begins Phase 2, (i.e., once the size of the school exceeds 200 students). The left turn lane should be about 150- feet in length and have a 90-foot taper. The right turn lane should be a minimum of200 feet in length (longer if possible) plus a 90-foot taper. A major concern with any elementary school is the queuing of vehicles while dropping off and picking up students at the school. With the proposed site plan, it is Page 22 Quarry Lane School Updated Traffic Study Abrams Associate~ Transportation. Traffic. Engineering. Ptannin . /g?? ;;':3!J expected that this will be contained within the school property. With 90 parking spaces for the first phase of the school, on-site parking will be sufficient for all normal weekday activities. With the second ph3$e (950 students), the parking will be expanded to about 175 spaces. During this stage, the on-site parking will continue to be adequate for the school demand. Quarry Lane School has plans to adopt a transportation management program (TSM) to reduce the number of single-occupant vehicles generated by the school. These plans would include the formation of carpools by parents at the school, defining the location of pickup/drop-off points for students, and defining the exact location of staff parking. Specific measures in the plan could include: · assigning a specific TSM Program Coordinator · orientation of all new staff and parents · management and control of drop-off and pick-up locations · carpooling incentives - set a target goal of2.0 students per vehicle · defming the travel routes for parent vehicles, and · coordination with the City of Dublin This type of program has been successful at other schools. It is expected that this TSM program would reduce the trip generation below the level that has been estimated in this report. Abrams Associate Transportation. Traffic. Engineering.

The CRITICAL MOVEMENT ANALYSISMETHODOLOGy2, which is described in Transportation Research Board's Circular 2t2,defines Level of Service (LOS) forsighalizecr intersections in terms of the ratio of critical movement traffic volumes to an estimate of the maximum capacity for critical volume at an intersection. Critical mQvemepts atan intersection are calculated byd,etermining the maximum traffic volumes for conflicting traffic movements (i.e., left-turns plus opposing through traffic) per single stream of traffic (by lane). For the Critical Movement Methodology the LOS for intersections is determined by the ratio of critical movement volume to critical movement capacity (volume,..to,..capacity ratio = V IC) for the entire intersection. Six qategories of LOS are defined, ranging from LOS "A" with minor delay to LOS "F" with delays averaging more than 40 seconds duringthe peak hour.
