PROJECT DESCRIPTION:
The project site is located north of the existing city limits, on the east side of Tassajara Road,
approximately 2 miles north ofI-580 within unincorporated Alameda County. The site contains two
properties, the Quarry Lane School and the Kobold property, located at 6363 and 6237 Tassajara Road
respectively. The Kobold property is located adjacent 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. Phase 2 of Quarry Lane School would include
the construction of 66, 685 square feet of classroom and administrative space to house 750 students and
55 staff and recreational play fields. 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 District is requested to
obtain the necessary level and range of urban services to facilitate future expansion of the school. The
State reorganization act (Knox-Cortese) requires that properties proposed for annexation be contiguous
with the boundaries of the jurisdiction to which annexation is proposed. Therefore, the Kobold property
is proposed to be included in the annexation action, since it is the intervening property between the city
limits and the Quarry Lane School site. However, no development is proposed for the Kobold property at
this time.
The proposed 'Proiect includes the following entitlements:
. Planned Development Prezoning and Stage 1 and 2 Development for Phase 2 of the Quarry Lane
School
. Planned Development Prezoning of the Kobold property to allow future residential and open space '
uses in accordance with the Eastern Dublin Specific Plan
2
. Annexation to the City of Dublin and Dublin San Ramon Services District.
A model of the proposed Quarry Lane School development will be presented at the City Council meeting.
BACKGROUND:
Although, the project site lies within a portion of unincorporated Alameda County, it is within the City of
Dublin's sphere of influence and within the Eastern Dublin Specific Plan area. The Specific Plan was
adopted by the City of Dublin in January of 1994, for the purpose of guiding future growth in the eastern
portions of the City and established land use designations for approximately 3,300 acres of land east of
the Camp Parks Military Reserve. Due to the characteristics of the project site, under the Specific Plan it
was given three separate land use designations of "Medium Density Residential", "Open Space" and
"Rural Residential/Agriculture".
The Quarry Lane School site was previously known as the "Villa Tassajara", with an existing building
and parking lot used primarily for a variety of social gatherings, including weddings, training seminars
and similar events.
In April 1999, Alameda County approved a rezoning for the property to PD- Planned Development
District to allow the Phase 1 development for Quarry Lane School, consisting of 15, 600 square feet of
floor area for day care, preschool and elementary grades with a maximum of 200 students. The school
would be served by private on-site well and septic facilities. Phase 1 of the school opened in mid-
September for the 2000/01 school year.
The County also certified an Environmental Impact Report for Quarry Lane School prior to the approval
of the rezoning and development application. The EIR considered the full build-out of Quarry Lane
School consisting of 62, 575 square feet of floor area for day care, preschool, elementary, middle and high
school grades to accommodate a maximum of 950 students.
ANALYSIS:
Project Site and Surrounding Land Uses:
The project site encompasses two parcels of land, the Quarry Lane School property and the Kobold
property located east of Tassajara Road, north ofthe current City limits within the Eastern Dublin Specific
Plan area. The subject site contains the existing Villa Tassajara building which has been incorporated into
the Quarry Lane School as the administration building and the Phase 1 school building. A single-family
residence, landscape contracting business and plant nursery exists on the Kobold property.
The Quarry Lane School site contains moderate to steep topographic features, with natural (pre-graded)
elevations ranging from approximately 435 feet above sea level adjacent to Tassajara Road to
approximately 564 feet above sea level (the highest point) on the northeast comer ofthe site. The Villa
Tassajara building and parking lot has been constructed on the level portion ofthe site adjacent to
Tassajara Road. At the rear ofthe parking lot the pre-graded topography rose steeply to form a small hill
towards the center ofthe property at the 500-foot contour. A tributary of Tassajara Creek exists along the
southern boundary of the Kobold property. The Specific Plan designation of Rural
Residential! Agriculture encompasses the northeastern portion of the Quarry Lane School site generally
located above the 500-foot contour line. The southern portion of the Kobold site along the tributary of
Tassajara Creek is designated for Open Space uses and the remainder ofthe west, northwest and central
portions of the total site (Quarry Lane School and Kobold) are de~ignated for Medium Density Residential
land uses.
3
To the northeast of the site, a single-family residence has been constructed on a la-acre lot. The property
to the south of the creek is currently being constructed with single-family residences as part of the Dublin
Ranch development. To the east, lands designated for a Community Park and Rural Residential
Agriculture under the Eastern Dublin Specific Plan are undeveloped. Across Tassajara Road to the west,
lie vacant lands designated for future residential uses under the Eastern Dublin Specific Plan.
Planned Development
Quarry Lane School:
The Applicant is requesting a Planned Development Prezone and Stage 1 and 2 Development Plan to
establish regulations for the use, development, improvement, and maintenance of the property as required
by Chapter 8.32 of the Dublin Zoning Ordinance.
The proposed land uses are shown on the Prezoning Exhibit, labeled Exhibit A-I of Attachment 2 to the
staff report. A Stage 1 and 2 Development Plan has been prepared for the Quarry Lane School, depicting
development concept and addressing the requirements of the Zoning Ordinance. The proposed
Development Plan is attached and consists of: ExhibitA-2, the Planned Development Provisions
(including permitted and conditional uses and development regulations) and Exhibit A-3, the applicants
proposed site, architectural, landscape and other plans.
Development Plan
The Development Plan as proposed would allow the operation and construction of a private school
including kindergarten through high school grades for a maximum of 950 students (phase 1 and 2) and
approximately 55 faculty and staff. The second phase of construction would include 66, 685 square feet
of floor area to accommodate new classrooms, a gymnasium, new recreational play fields, driveways and
parking areas.
The following table summarizes the amount of construction proposed for each phase of development:
Table 1. Summary of Quarry Lane School Development

Phase II (proposed

Dublin)
Total 82,263 , 50 950
The original site plan prepared by the Applicant for submittal to Alameda County in 1998 proposed the
complete grading of the property to provide a flat area to construct the school. The Applicant worked
closely with both the City and County to revise the site plan to minimize on-site grading and design
structures to more closely fit the natural topography. In 1999, the County approved the Phase 1 school
building only, located to the immediate rear of the existing parking lot area. This approval also permitted
the creation of a flat play area at the 500-foot contour and prohibited any grading above the 520-foot
contour line.
In order to accommodate the phase 2 improvements including a second school building and recreational
play fields; the applicant proposes to recontour the central portion of the property so that the small hill to
4
the rear of the phase 1 building is cut to accommodate the new school building. The new building has
been carefully designed to fit the contours of the existing topography. The three-story structure appears to
step up and into the hillside to reduce its mass and scale, thereby appearing as a two-story structure (Refer
to Exhibit A-3, Sheet A4.0). To the rear of this structure, a combination of cut and fill is used to create a
flat playfield site with a steep downslope to the southerly property line to meet natural grade. The area
will be landscaped with appropriate vegetation to promote stability and create a soft landscaped edge.
Several retaining walls are required as part of the development. The walls would range in size from less
than one foot to a maximum of 14 feet. The northeastern portion of the property between the recontoured
490 and 520 foot contours would be regraded to resemble the existing landform and the area above the
520-foot contour would be left undisturbed.
The Phase 2 architecture has been designed to match the Phase 1 architecture to create a uniform site
design. The architecture can be described as industrial rural with craftsman elements to complement the
rural setting and future residential land uses in the area. The building is characterized by use of stucco
finish, metal roofing, wood brackets, aluminum windows and decorative metal trim. The building has
been designed with varying roof elements, which effectively reduces the overall scale of the structure. In
addition, the building would not obscure or extend above the ridgeline. The ground level would contain
parking spaces and classrooms, with second and third floors accommodating the gymnasium and
additional office and classroom areas.
The Phase 1 school building is constructed in a similar manner to the proposed Phase 2 building and also
utilizes the existing topography to step up the hillside. The general appearance of the overall project
would be one of buildings walking up the natural landforms and stepping back from Tassajara Road. The
Phase 1 building will partially screen the Phase 2 structure proposed. The applicant is using the natural
landform rather than destroying it.
Landscaping of the property consists of streetscape landscaping, landscaping around the perimeter of the
buildings and playfield. The landscaping shall conform to the City of Dublin Master Streets cape Manual
and incorporate the use of native plants and shrubs; vegetation shall be chosen to promote slope
stabilization.
The site has been designed with adequate access and on-site pedestrian and vehicular circulation. Parking
has been provided in accordance with the City's Parking Ordinance.
Proposal to Revise Development Plan:
In response to comments from Mr. Nielsen, the property owner to the immediate north of the Quarry Lane
School site, the applicant, Dr. Arac proposed to revise the rear portion ofthe school. The revision
involved lowering the elevation ofthe play field and moving the play field approximately twenty feet to
the south (Kobold property). It was anticipated that moving the play field would reduce the noise levels
generated by outdoor school activities at the Nielsen residence.
Relocating the play field required the addition of new retaining walls along the north side of the play field
and the redesign of the access between the Phase 2 building and 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 third floor of the building to the play field for student access. Relocating the play
field closer to Kobold's property may result in additional noise and other impacts to that property. Also,
the revised site plan would require additional cutting of the hillside and the removal of more earth off-site.
5
Wilson, Ihrig and Associates, noise consultants reviewed the revised site plan to determine if there would
be any substantial change in noise levels as a result of lowering the elevation and moving the location of
the play field. Refer to Attachment 13, noise assessment-alternative 2 letter, dated November 7,2000.
The noise assessment determined that the revised site plan provides no additional noise reduction from the
play field at the Nielsen residence and slightly increases the play field noise at the Kobold residence.
After careful consideration of safety issues, noise, grading and visual impacts, it is staff s opinion that the
original site plan provides the best design solution for the project. Therefore, staff is not recommending
approval of the revised site plan.
Consistency with General Plan and Eastern Dublin Specific Plan:
The Eastern Dublin Specific Plan Specific / General Plan designates the property for Medium Density
residential and Rural Residential! Agricultural uses. A school use within this designation is appropriate
because the Eastern Dublin Specific Plan envisions this area (identified as subarea G: Foothill residential
in the Specific Plan) to be developed with predominantly residential and open space uses, as well as uses
including public schools and parks. It is appropriate for schools, both public and private to be located in
residential neighborhoods in close proximity to the students they serve.
The siting and design of on-site improvements has be carefully planned to accommodate the required
buildings but also to complement the existing site topography; minimize grading; ensure that the
development does not obscure or extend above the ridgeline; and recontour slopes to resemble natural
land forms consistent with the policies of the Specific Plan.
Kobold Property:
A Planned Development (PD) Prezoning has been prepared for the Kobold property to establish regulations
for future use. The proposed land uses are as shown on the Prezoning Exhibit, labeled Exhibit A-I of
Attachment 2 to the staff report. The proposed land uses are consistent with the Eastern Dublin Specific
Plan and General Plan land use designations of "Open Space" and "Medium Density Residential". The
draft PD District provisions (Attachment 2) specify the intent, intensity of use, permitted and conditional
uses ofthe Residential and Open Space land use designations in accordance with the Specific Plan. Any
future residential development on this property shall conform to the policies and intent of the Eastern
Dublin Specific Plan including the design guidelines. In accordance with the Specific Plan, the prezoning
identifies open space uses along the southern property line to preserve the creek corridor and provide
passive recreational areas. No development may occur until a Stage 1 and Stage 2 Development Plan is
adopted by the City identifying regulations for the improvement and maintenance of the property in
accordance with Dublin's Zoning Ordinance.
The "Interim Agricultural" land use designation (Attachment 2) allows the existing residential and
agricultural uses approved under the Alameda County's Zoning Ordinance to remain until such time as
the property owner applies for a Development Plan to develop the property. The regulations and
standards governing this land use designation shall be the Agricultural Districts (A Districts) provisions of
the Alameda County Zoning Ordinance. Also, following annexation, all City of Dublin zoning provisions
relating to legal non-conforming uses and buildings shall apply to this property.
Annexation
The project site is currently within unincorporated portion of Alameda County. In order for the project to
come under the jurisdiction of the City of Dublin, annexation of the site to the City must be approved by
the Alameda County Local Agency Formation Commission (LAFCo). The LAFCo prefers that a city
prezone an area proposed for annexation, and that prezoning must be consistent with the approved
General Plan and Specific Plan uses for the property. The PD Prezoning proposed for adoption would
6
address this requirement, and would establish the appropriate land uses to be in effect at the time the
project site becomes a part of the city.
The current action proposed for the City Council is to consider the draft resolution (Attachment 3)
authorizing staffto file an application to LAFCo for a reorganization. The reorganization proposal
includes the annexation of 15.07 acres (the Quarry Lane School site, Kobold property and a portion of
Tassajara Road) to the City of Dublin and Dublin San Ramon Services District.
LAFCo and State law also requires an agreement between the City and the other affected taxing entities
regarding the exchange of property tax revenues following annexation. The City and Alameda County are
parties to an agreement which provides that the City will receive 25.4% of the property tax revenues from
the areaproposed to be annexed. The City has received a letter from Alameda County confirming that the
proposed annexation is subject to the terms of this agreement including the transfer of property taxes to
the City following annexation. Staff recommends the City Council adopt Resolution Attachment 4
agreeing formally to the transfer of these property taxes following annexation.
The provision of public services is outlined in the "Plan for Municipal Services" (Exhibit B-5 of
Attachment 3) document that describes the timing and availability of services for the proposed annexation
area. Dublin San Ramon Services District will provide potable water and wastewater collection, treatment
and disposal services. As stated in the Plan for Services, DSRSD has adequate water supplies and sewer
capacity to provide service to the annexation area. However, water and sewer for this annexation may not
be available immediately upon approval of annexation. Detailed engineering and construction plans for
water and sewer infrastructure will be required to address service to the annexation area, and the project
proponent will likely need to enter into an agreement with the District. Following annexation Fire and
Police protection services will be provided by the City of Dublin. Utilities such as electricity and
telephones will continue to be provided by P G & E.
The proposed annexation is appropriate, as it is contiguous with the Dublin City limits and would provide
for the logical and orderly extension of urban services within the Eastern Dublin Specific Plan Area.
ENVIRONMENTAL REVIEW
The project 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 ErR is a program EIR, which analyzed the ~nvironmental
issues related to the land use locations, development plans and 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 impacts from implementation of the General Plan/Specific Plan that were not
able to be mitigated. Upon certification of the EIR, the City adopted a Statement of Overriding
Considerations for several impacts, some of which relate to this project. The City also adopted a
mitigation monitoring program, which included measures intended to reduce impacts from the
development of Eastern Dublin area. These mitigation measures apply to project approvals and actions at
various stages in the development process, and will be applied to this project as applicable. The timing 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 Quarry Lane School was certified by Alameda County Board of
Supervisors in 1999. The EIR analyzed environmental issues relating to the proposed school in the areas
of land use, visual quality, geology, hydrology, traffic and circulation, air quality, noise, public services
7
and utilities. Upon certification of the EIR, the Board of Supervisors adopted a Statement of Overriding
Considerations for impacts relating to high noise levels as a result of construction activity and adopted a
mitigation' monitoring program.
An Initial Study was prepared for the proposed project, involving an annexation and prezoning request for
6363 and 6237 Tassajara Road. The Initial Study utilized technical information and analysis in both the
Eastern Dublin EIR and the County EIR to determine if additional impacts would occur as a result of this
proposal. The Initial Study determined that with the implementation of Mitigation Measures previously
adopted for the Eastern Dublin EIR and with site specific Mitigation Measures contained in the Initial
Study, the potential site-specific impacts of the project would be reduced to a level of insignificance and
the proposed project will not have a significant effect on the environment. The public review period of
the Initial Study/Mitigated Negative Declaration was held from July 19,2000 through August 7,2000. A
copy of the Initial Study/Mitigated Negative Declaration is included as Attachment 6. During the Public
Comment period four comment letters were received from Mr. Kyle, Attorney representing Mr. Nielsen (the
property owner to the immediate north of the project site), local and State agencies, including the Regional
Water Quality Control Board, East Bay Regional Park District and Alameda County Flood Control and
Water Conservation District, Zone 7. Staffhas prepared responses to each of these letters. The comment
letters and responses are attached as Attachment 7 to this staff report.
The letter received from Mr. Kyle focused on two issues, the potential grading and noise impacts that could
result from the development of the proposed Phase 2 site plan for Quarry lane School. Mr. Kyle requests
that a new ElR should be prepared to address the environmental impacts of this site plan. The agencies
comments primarily related to issues of stormwater 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 the opportunity to meet with the School to discuss these
issues. The City's response to each of these comment letters is attached as Attachment 7 to this staffreport.
The following is a brief discussion of the pertinent 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 Kobold 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 significant traffic impacts as a result ofthis project. The program
EIRdetermined that the development of Eastern 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 development within the eastern Dublin area. The Applicant will be required to pay traffic
fees as part of this. development.
Visual and Grading: The project was evaluated to determine whether the project design complies with the
mitigation measures of the Eastern Dublin EIR and the Eastern Dublin Scenic Corridor policies. A
number of these policies have been reflected in the project design to minimize visual impacts, site
grading, the number and height of retaining walls and to design the building to fit the existing topography.
With the adherence to mitigation measures of the Eastern Dublin EIR and site-specific measures identified
in the Initial Study, no significant impacts were identified for the project.
Noise: The County EIR for the Quarry Lane School analyzed the potential noise impacts of the project
and determined 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 and 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, Response to
Comments) to evaluate potential noise impacts as a result of the revised Phase 2 site plan. The noise
study was further revised in response to comments from the City's Acoustical Consultant, refer to ,
Attachments 12 and 13. The study analyzed noise that would result from circulation of traffic to the
parking lots on-site, noise from students at play at the recreational area and noise from the Phase 2
building and assessed the noise impact on adjacent properties. The study concluded that noise produced
by the Quarry Lane School would not significantly impact noise levels at adjacent residences. The Quarry
Lane School traffic and play area activities would only occur for relatively short periods of time and
primarily during daytime hours, when school is in session. The adjacent residences would be largely
shielded from the noise generated by children at the recreational playfield by both distance and
topography of the site.
OTHER AGENCY IDEP ARTMENT REVIEW
The proposed project has been reviewed by the Building Department, the Public Works Department,
Police Services and Alameda County Fire Department. The concerns raised are reflected in the design of
the project and / or in the mitigation measures identified in the Initial Study/Mitigated Negative
Declaration prepared for the project
PRE-ANNEXATION AGREEMENT
The goals and policies of the Eastern Dublin Specific Plan require annexation and new development to be
revenue neutral. It is estimated that the cost of providing public services to the Eastern Dublin Area
(including the annexation area) could exceed revenues over 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 ofthe 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. The agreement 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 ofthe 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 work with other property owners within the City of
Dublin's sphere ofInfluence to initiate and complete the annexation process to the Dublin Unified School
District.
CONCLUSIONS
The proposed Planned Development Prezone and Annexation request for the Quarry Lane School and
Kobold properties is consistent with the Dublin General Plan, Eastern Dublin Specific Plan and Dublin
Zoning Ordinance. The project will accommodate the logical extension of public services within Eastern
Dublin and will provide for future land uses anticipated in the Eastern Dublin Specific Plan.

area of open space and undisturbed hillside along the north and primarily the northeast comer of the
property; and will be compatible with and enhance the general development of the 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

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 ofthe Dublin
General Plan and the Eastern Dublin Specific Plan; and
9. The Planned Development Prezone will benefit the public necessity, convenience and
general welfare; and

area designated for open space uses along the southern portion of the property to preserve the creek
corridor and provide passive recreational areas; will be compatible with and enhance the general

RESOLUTION NO.
A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF DUBLIN
AUTHORIZING INITIATION OF APPLICATION FOR REORGANIZATION
FOR P A 99-064, ANNEXATION NO. 12
WHEREAS, the applicant, Dr. Sabri Arac of Quarry Lane School has submitted a request for
annexing I5.07::!:: acres to the City of Dublin and annexing 15.07::!:: acres to Dublin San Ramon Services
District; and
WHEREAS, pursuant to the Cortese-Knox Government Reorganization Act of 1985 (the "Act")
(Government Code Section 56000 et seq.) an affected city and affected district, as therein defined, may by
resolution adopted by its legislative body make a proposal for a "reorganization", as defined in Section
56073 and request initiation of proceedings thereon;
WHEREAS, the City of Dublin is an affected city, and the Dublin San Ramon Services District
(DSRSD) is an affected district for a reorganization proposal which contains territory proposed to be
annexed to said city and to DSRSD.
WHEREAS, the City of Dublin is an affected local agency for this reorganIzation proposal.
WHEREAS, the reorganization proposal is made pursuant to the Act. The proposal would annex
15.07::!:: acres to the City of Dublin and 15.07::!:: acres to the Dublin San Ramon Services District; and
WHEREAS, the territory described in Exhibit B-1 and B-2 is uninhabited territory within the
meaning of Government Code Section 56046.
WHEREAS, the exterior boundaries of the territory described in Exhibit B-1 and B-2 are shown
on Exhibits B-3 and B-4; and
WHEREAS, this reorganization is proposed at the request of Dr. Arac, the landowner owning
approximately 60% of the land within the territory to be annexed. The reorganization would implement
the City of Dublin's Eastern Dublin Specific Plan; and
WHEREAS, the 'Plan for Services' for the territory to be annexed is set forth in Exhibit B-5
WHEREAS, the potential environmental effects of development on the Quarry Lane School
project site has been previously addressed in the Eastern Dublin Specific Plan EIR (SCH No. 91-103064);
and
WHEREAS, an Initial Study has been prepared for the Quarry Lane School project, including a
Planned Development (PD) Prezoning, Annexation to the City and DSRSD and subsequent development
ATTACHMENT 3
>\ ~ tS'?:>
entitlements to evaluate site-specific impacts of the project pursuant to CEQA guidelines Section 15168. '
Based on the Initial Study, a Mitigated Negative Declaration and Mitigated Monitoring Program has been
prepared for the project with the finding that with the implementation of Mitigation Measures previously
adopted for the Eastern Dublin Specific Plan EIR and with site specific Mitigation Measures contained in
the Initial Study, the potential site-specific impacts of the project would be reduced to a level of
insignificance. The Eastern Dublin Specific Plan EIR and Initial Study adequately describe the impacts of
the project, and there have been no substantial changes or new information that would be outside the
scope of the Eastern Dublin Specific Plan EIR; and
WHEREAS, a total of four letters commenting on the Mitigated Negative Declaration were
received during the public comment period; and
WHEREAS, all pertinent comments have been responded to and have become part of the
Response to Comments attached as Attachment 9 to the Staff Report for P A 99-064; and
WHEREAS, the proposed reorganization would be conditional upon agreement of Dublin San
Ramon Services District for annexation of the territory to Dublin San Ramon Services District, and
WHEREAS, this proposal is consistent with the City of Dublin and DSRSD's sphere of influence,
and
WHEREAS, if determined appropriate by the LAFCo, the City Council consents to act as the
conducting authority for the proposed reorganization, and
WHEREAS, a notice of the City Council public hearing to consider an application for
reorganization to the Alameda County Local Agency Formation Commission (LAFCo) was distributed to
all public service providers and interested individuals; and
WHEREAS, the City and the applicant have been cooperatively planning for the provision of
services to the project site and have notified the service providers of the proposed annexation; and
WHEREAS, the City Council held a properly noticed public hearing on the Quarry Lane School
project, Planned Development Prezoning, and Annexation on November 21,2000, and considered all
written and oral testimony submitted at or prior to the public hearing; and
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF DUBLIN DOES
HEREBY RESOLVE AS FOLLOWS:
A. The foregoing recitals are true and correct.
B. The City Council of the City of Dublin, as the legislative body for an affected local agency, does
hereby adopt the foregoing recitals and makes a proposal for a reorganization, as described herein,
pursuant to Section 56800 ofthe Cortese-Knox Act, and does hereby request that proceedings be
taken pursuant to said Act.
C. This proposal is consistent with the sphere of influence of the City of Dublin.
:J ~ 66 IS3
D. The proposed annexation is appropriate because it is contiguous to the existing city limits and
would provide a logical extension of development under the City's jurisdiction to provide a private
school, residential, and open space land uses for the community.
E. This proposal is made subject to the following terms and conditions:
1. The description and the maps in Exhibits B-1, B-2, B-3 and B-4 are preliminary
and are subject to more detailed description(s) and map(s) to be prepared and '
submitted to the LAFCo. Adjustments to the descriptions and maps of the territory
are to be made as deemed necessary by the County Surveyor.
2. The annexation to the City of Dublin is conditional upon agreement of Dublin San
Ramon Services District (DSRSD) for annexation of the territory to DSRSD. The
Community Development Director is hereby directed to acquire an agreement from
DSRSD to participate in this reorganization.
3. An agreement for payment of service costs satisfactory to the City shall be executed

PLAN FOR MUNICIPAL SERVICES
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 of land 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 ofland 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 ofland 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 include 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 1 ofthe 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 ofthe Kobold property. Phase 1 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
':j ( . ~ I s~
District has been requested to obtain the necessary level and range of urban services to
facilitate future expansion of the school.
Availability of Services:
As shown in this Plan for Services the agencies responsible for providing services to the
annexation area are know at this time. DSRSD would provide water, recycled water and
wastewater services to the annexation area. Infrastructure would need to be extended
from Tassajara Road (south of existing city limits) to service the project area. Capacity
to provide all services to the annexation area either currently exists, is scheduled through
contract to be provided in the future, or will be available as soon as funding from the
developer is provided.
Annexation Justification:
The following reasons justify the size and configuration of this proposed annexation.
Firstly, annexing just the Quarry Lane School property would result in the creation of an
island or unincorporated corridor. Therefore, the Kobold property is proposed to be
included in the annexation, since it is the intervening property between the city limits and
the Quarry Lane School site. Secondly, the proposed annexation configuration follows
existing property lines, and is a logical extension of the existing Dublin City limits.
Thirdly, the annexation includes a portion of Tassajara Road providing proper access to
the annexation area. Fourth, the proposed annexation to DSRSD is consistent with the
Dublin General Plan and Eastern Dublin Specific Plan. Fifth, on completion, the Quarry
Lane School would provide private educational opportunities for students living within
Eastern Dublin.
SERVICES
The Eastern Dublin Specific Plan and program EIR (1994) were prepared with the
knowledge that it would be used for the annexation to the City of Dublin and Dublin San
Ramon Services District, and as a basis for the Plan for Municipal Services for the area.
Special care was taken during the preparation of these documents to insure that the
analysis of services provided therein would be thorough and thereby satisfy the
requirements of the Alameda County Local Agency Formation Commission (LAFCo) for
annexation actions. Both documents were referred to, reviewed by and commented upon
by LAFCo staff and those comments were incorporated into final drafts of the Plan and
EIR. DSRSD reviewed the documents to ensure that they would support the future
discretionary action of the District to annex Eastern Dublin properties. The District
determined that the draft EIR presented a through analysis ofthe impacts of the project
on water and wastewater services keeping in mind the District's master plan models for
water, wastewater and recycled water would need to be after adoption of the Specific
Plan. This task is required by mitigation measures of the EIR and accomplished through
completion of the report entitled "Eastern Dublin Facilities Plan Final Report" (G.S.
Dodson and Associates, December, 1993) and more recently by the "Urban Water
Management Plan", DSRSD, May, 2000 and the "Plan for Services for the Quarry Lane
School annexation", DSRSD, October 2000.
An Initial Study and Mitigated Negative Declaration was prepared for the proposed
annexation to evaluate the site-specific impacts of the project to a greater level of detail
than in the program EIR. The Eastern Dublin Specific Plan and program EIR in
3
3'2. ~ IS.?;
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 SchoollKobold
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 SchoollKobold 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 ofthe 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
Sheriffs 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
=)3 ~ \53
As development in Eastern Dublin is completed and occupied, additional officers and
services are planned to serve the east Dublin residents. According to 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 classes
may be required. If necessary this position will be funded by the City.
FIRE PROTECTION
At the present time, fire protection services to the annexation area are provided by the
Alameda County Fire Department and the California Division of Forestry. Currently the
City's fire protection services are provided by the Dublin Division of Alameda County
Fire Department (ACFD) and funded by the City through a contractual agreement with
the County. With annexation, the Dublin Division of Alameda County Fire Department
would become responsible for fire services. Under the terms of the agreement, all
Alameda County fire protection personnel and services would be available 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 north 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'oftwo new stations in order to maintain these
standard response times. The new stations would be located at Madigan Road, north of
Gleason Drive and east of Fallon Road and would be operational by 2003 and 2004,
respectively. According to ACFD, sufficient fire protection personnel, facilities and
equipment currently exist to serve the proposed annexation area.
SOLID WASTE
Coordination of solid waste management activities in Alameda County is a joint
responsibility of the County's Waste Management Authority and local jurisdictions. The
City of Dublin presently contracts with a private company for residential and commercial
garbage collection within the city limits. When annexation takes place, this private
company will also provide waste collection services to the area.
PARKS AND RECREATION
The annexation area is currently ' under the jurisdiction of the East Bay Regional Park
District (EBRPD). The annexation area which totals approximately 13 .6 acres (Quarry
Lane School and Kobold 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 community parks, park maintenance and organization of
recreational services will 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 annexation area. To date, the first
phase of a 50-acre Community Park (Emerald Glen Park) was recently opened to the
5

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 located 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 ofthe 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.

PLAN FOR PROVIDING SERVICES
POTABLE WATER
WASTEWATER COLLECTION, TREATMENT AND DISPOSAL
Quarry LanelKobold 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 thesewer 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 bv virtue of this report. The final 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 EXHIBIT B-5
~ ~ IS~~
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
.UWMP was approved by the Board of Directors on May 16,2000. The UWMP includes
demandprojections for all expected future development demands, including 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 required addition to the potable source for those
specified acceptable irrigation uses.
?:>l 6 153
Although the landscape irrigation represented by the school would be an acceptable recycled
water use pursuant to Ordinance 280, it has been determined that the existing potable water well
currently utilized for Phase 1 of the Quarry Lane School is adequate to be used for irrigation
water when Phase 2 is constructed. Therefore, although the project's irrigation demands will not
be required to connect to the District's recycled water system, neither will they become a demand
upon the District's potable supplies. It is not expected that any recycled water will be used by .
the Kobold property, as any development 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 1993. Wastewater flows for the annexation territory are estimated
as follows:
Quarry Lane School:
. Approximately 4 gallons 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 ~pd / 220 gal per
,equivalent connection)
Kobold Property:
. One existing single family dwelling
. Potential for maximum of25 homes (terrain dictates highly unlikely more than 8
additional homes)
. At 220 gpd per home, 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 approved, 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
jco
o~ ! S~3
o
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 north to 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 ofthe 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 Stoneridge 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 Pleasant on. 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 of DSRSD 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
:)'1 06 IS.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 ofthe expansion is complete,
and construction of the repair/expansion awaits the member agencies' approval ofthe 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.

ANNEXATION AGREEMENT
BETWEEN CITY OF DUBLIN AND DR. SABRI ARAC
FOR THE QUARRY LANE SCHOOL PROJECT
THIS AGREEMENTdated 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 ("the 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 ~nd 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, "the 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.

City of Dublin and Dr. Sabri Arac- Quarry Lane School
EX H I BIT Govemb:~~;, ~~~~
y ~ D 16""3
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 SpE:lcific Plan, Developer will pay City Developer's proportionate 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 1-580lTassajara 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
ofthe Annexation Area will benefit from 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 Developer 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 deficit 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.

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

Environmental Checklist/
Initial Study
Introduction
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. Existing site
uses include the Phase I construction of the private Quarry Lane School and an existing building (Villa
Tassajara) that has been incorporated into the Quarry Lane 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 ofthe 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 project 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-tenn 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.

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
15,600 square feet of floor area for day care, preschool and elementary grades with a maximum of200
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 EIR included the full 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 vehicles. Landscaping would also be provided on the site.
The following table summarizes the amowlt of construction proposed for each phase of project
development:

Exhibit 3 shows the site plan for the proposed ultimate construction of the Quarry Lane School, including
the existing, approved phase (Phase 1) and the proposed second phase. 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 behilJ.d the new classroom building to create a flat playfield
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 ofthe
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 land
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 8.32 ofthe
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.

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 of the Quarry Lane school has
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 SanRamon 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 Local 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 ofjhe entitlement process for the project,
pursuant to Chapter 8.104, of the Dublin Zoning Ordinance. The purpose of Site Development Review is
to promote the orderly, attractive and harmonious development within the City and to ensure compliance
with all applicable development regulations of the Zoning Ordinance.

Environmental Factors Potentially Affected
The environmental factors checked below would be potentially affected by this project, involving at least
one impact that is a "potentially significant impact" as indicated by the checklist on the following pages.
X Aesthetics - Agricultural X Air Quality
Resources
- Biological Resources X Cultural Resources X Geology/Soils
Hazards and Hydrology/Water - Land U se/ Planning
- Hazardous Materials X Quality
- Mineral Resources X Noise - Population/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 find that the proposed project could not have a significant effect on the environment and a Negative
Declaration will be prepared.
l 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, including revisions or mitigation measures that are imposed on the propbsed
project.

Evaluation of Environmental Impacts
1) A brief explanation is required for all answers except "no impacttl answers that are adequately
supported by the information sources a lead agency cites in the parenthesis following each question.
A tlno impacttl 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 tlno impacttl 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 tlpotentially significant effect"
to a "less than significant impact.tI The lead agency must describe the mitigation measures and
briefly explain how they reduce the effect to a less than significant level.

I. Aesthetics
Environmental Setting
The project site contains the initial phase ofthe 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 maj or 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 project site is located within the Tassajara Road scenic corridor, so designated by both the City of
Dublin and Alameda County. The previous EIR certified by the County for the project identified a number
of mitigation measures to ensure potential visual impacts of proj~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 to 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 project site. For this area, the Guidelines suggestthe
following policies and standards:
City of Dublin
Initial Study/Quarry Lane School
P A 99-064
Page 27
July 2000
cst l C ')"
oJ '.#
· 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 comer 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.

b) Substantially damage scenic resources, including state scenic highway? LS/M.
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 lighting, 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
areasthat 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 DublinPolice 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 of local importance (Impact 3. liD)
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. .

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-10) are not met in at leasta
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 summarized 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 Easterh 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 ofthe 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 3.11/1.0 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 Dublm
Initial Study/Quarry Lane School
P A 99-064
Page 30
July 2000
qe 'i ls3
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 "non-
native grasslands." Non-native grasslands are characterized as introduced annualweedy 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 been disturbed by grading
and building activities associated with Phase One construction ofthe 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 of Tassajara 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 Kobold site 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
PA 99-064
Page 31
July 2000
'41 ~b 153
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, f) Conflict with local policies or ordinances protecting biological resources or any adopted Habitat
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 Kobold site 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 Setting
The Eastern Dublin area was surveyed in 1988 as part of the Eastern Dublin Specific Plan and associated
ElR. 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 exist on the subject
site. There would therefore be no impacts to historical resources. .
City of Dublin
Initial Study/Quarry Lane School.
P A 99-064
Page 32
July 2000
41 i l'5'3
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
Environmental Setting
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 the "Mocho Fault").
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 Mocho 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 "leading edge-blind thrust, Mount Diablo Domain." Further
investigation of this inferred faultby 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.

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 flat with a gradual slope towards the unnamed tributary of Tassajara 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
summarized 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 of landslides and expansive soils as part of the
geotechnical report.
Project Impacts and Mitigation Measures
a) Expose people or structures to potential substantial adverse impacts, including loss, injury or 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 ErR 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 other City requirements for grading. Nicholas Engineering Consultants have prepared

preliminary soils reports dated June 1, 1999 and June 12,2000, that contains specific
recominendations 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 final 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 5a: 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 5b: Prior to issuance of grading permit by the City of Dublin, the
project developer shall submit a Slope Stabilization Program addressing the steep slope 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 of the 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 and
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 EIR 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.

VII. Hazards and Hazardous Materials
EnvirOrimental Setting
The site is partially vacant and contains Phase 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.
Proiect 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 additional phases of the
Quarry Lane School and continued use of the 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 or release 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? NI. Adequate emergency access will be provided
via proposed driveways onto Tassajara Road. On-site access will be reviewed during the Site
Development Reviewprocess. 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 project site lies adjacent 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 firefighting 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 within 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. Stormwater 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 finally 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 immediately to the south of the
school. No major storm drain lines serve the site and it is not located within a 100-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 Dublin
Initial Study/Quarry Lane School
P A 99-064
Page 36
July 2000
,\b ~b \53
· 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.
Project Impacts and Mitigation Measures
a) Violate any water quality standards or waste discharge requirements? LS/M. Construction of
improvements anticipated as part of the 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 ofIntent 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/Z) 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 stormwater 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 would not be affected by stormwater runoff from the site, the
following mitigation measure shall be adhered to:
City of Dublin

Ot "5-"
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 stormwater 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 inflooding, either on or off the project 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 100-year flood elevation.
e) Create storm water runoff that would exceed the capacity of drainage systems or add substantial
amounts of polluted runoff? 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? LS/M. Refer to the analysis and mitigation measure under "a,"
above.
g) Place housing within a I DO-year flood hazard area as mapped by a Flood Insurance Rate Map? NI.
The proposed project does not include a housing component, so there would be no impacts with
regard to placing housing within a 100-year flood plain:
h, i) Place within a I DO-year flood hazard boundary structures that impeded or redirectfloodflow,
including dam failures? LS. The proposed project would not place structures within a 100-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 mudflows? NT. The site isnot 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 ofthe Eastern
Dublin ErR).

IX. 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 and has 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.

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, defined as 60 decibels CNEL for exterior noise for
residential land uses.
A number of rnitigation 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.
Project Impacts and Mitigation Measures
a) Would the project expose persons or generation of noise 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 ,day, when school is in session.
Mitigation Measures 3.10/4.0 and 5.0 contained in the Eastern Dublin EIRwill control short-term
construction noise. These measures r~quire the project developer to prepare a Construction Noise
Mitigation Plan and to comply with the City's Noise Management Ordinance.
b) Exposure of people to excessive groundborne vibration or groundborne noise levels? LS. Approval
of the projectwould 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;" 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," above.
e, f) For a project located within an airport land use plan, would the project expose people to excessive
noise levels? NI. 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.

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 cornparison, 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 of9,737,000 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 ofthe 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
1()1 ~b IS?>
· 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 ~nd to assist in
reducing impacts would include installation 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 Uniform 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? NI. 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 Dublin 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 tax 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.

XlV. Recreation
Environmental Setting
There are no parks or other recreational facilities on the project site.
Proiect Impacts and Mitigation Measures
a) Would the project increase the use of existing neighborhood or regional parks? NI. The proposed
project would notresult 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 recreational facilities or require the construction of recreational facilities?
NI. 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 of the 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 of Danville. 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 1-
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 of Tassajara 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.

Existing Intersection Operations
The traffic analysis prepared by Abrams Associates found that existing intersections near the project 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.
· Tassajara Rd.lI-580 WB Ramps
· Tassajara Rd./Dublin Blvd.
· Tassajara Rd.lGleason Dr.
· Tassajara Rd.lProject 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 ofI-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 "D" or better. The Tassajara Road/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 Dublin

\(:jL.\. e~ \5, 0
· 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? LS/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 to local 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 "D" 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:

t \) S" <r6 \ S",
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.; close 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 the Alameda 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? LS/M. 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 TassajaraRoad. 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.
Mitigation Measure 10: In the event that the 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 staffwho 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 Dublm

I t.\~ t}b fS3
· 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 ofthe project would be less-than-significance.
b) Require new water or wastewater treatmentfacilities or expansion ofexistingfacilities? 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 drainagefacilities? 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 ElK 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 Eastern Dublin
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 Dublin Page 47
Initial Study/Quarry Lane School July 2000
PA 99-064
IGl cY~ 15~
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 degrade the quality of the environment, substantially reduce
the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-
sustaining levels, threaten to eliminate a plant or animal community, reduce the number 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?
("Cumulatively considerable" means that the incremental effects of a project are considerable when
viewed in connection with the effects of past projects, the effects of other current projects and the
effects of probable future projects). 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.

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 1: Comment 1: Since the project would disturb more than 5 acres of land during
construction, a Notice ofIntent 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
Stormwater 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 of the
overall project site for which immediate development is being proposed. It appears wetlands
exist on a portion ofthe 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 I: 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
\ \ \ tit \53
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 ofthe 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 oftrespass onto Camp Parks
property is considered low.
Comme:l1t 3: Although no development is proposed for the Kobold site at this time, additional
runoff and soil erosion may impact Tassajara 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 Negative Declaration and
County EIR. 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. Ifultimately, 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.

l\'2... tb 1'53
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
\\~ IJ~ ,s3
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 Eastern Dublin 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 for a project, a supplemental or subsequent EIR is only required
to be prepared if I) 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 500-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 of the site at the 500-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
HI{ ~lS;>
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 500-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 ofthe 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
ll5 ~ \53
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 segregated 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 rehitively 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 and faculty are located within
the gymnasium and the gymnasium doors and exterior windows 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 accommodate 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
\l6 ~ (5""3
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 significant impact.
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 project. 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. Refer to Comment 1 and 6 above for additional responses.

Re: Quarry Lane School, Annexation and Prezone, Mitigated Negative Declaration
Dear Mr. Peabody:
We have received the above referenced mitigated negative declaration and offer the following
comments with which the Regional Board is concerned.
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 ofIntent 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 of the local agency and the R WQCB.
2. This project may create runoff water that would exceed the capacity of existing or planned
stormwater drainage systems or provided additional sources of polluted runoff. In addition,
substantial alterations to the drainage pattern of the site may result. in substantial erosion or
siltation. Therefore, proj ect 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 and/or county),
and the Staff Recommendations of the RWQCB. Preparation of a SWPPP should be a condition
of development. Implementation of the SWPPP should be enforced during the construction

unavoidable adverse impacts to wetlands or waters of the State must 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. lfthe project
will disturb any jurisdictional wetlands or waters of the State, SeGtion 401 Water Quality

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
estabiishes broad state authority for regulation of water quality. The San Francisco Bay Basin Water
Quality Control Plan (Basin Plan) explains the Regional Board'sstrategy 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)
Stormwater 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 NOI and the General Permit can be obtained from the
Board at (510) 266-2300. 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 ofIntent. The project
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 \TI~y apply for (or the
RWQCB 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
this 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.

In general, if a proposed project impacts wetlands or Waters of the State and the project applicant
is unable to demonstrate that the project was unable to avoid adverse impacts to wetlands or Waters 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
Stonn 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 stonn 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 storm water flow
increased by newly develop'ed impervious surfaces, whi.ch will mobilize and' transport .ppllutants
deposited on these surfaces to stonn 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 Pennit or to develop a Baseline Urban Runoff Program (if they are not yet a co-permittee
with a Municipal Stonn Water Pennit), 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 stonn 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 Pennit
(General Permit). The SWPPP should be consistent with the terms of the General Pennit, 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 SWPPPshould be enforced during the construction period via
appropriate options such as citations, stop work orders, or withholding occupancy pennits.
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 BASMAA's
Start at the Source, and in the California Storm Water Best Management Practice Handbooks.

)2.\ ($& \'5'3
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 and for routine vehicle and equipment maintenance. . .
. Routinely maintain all vehicles and heavy equipment to avoid leaks.
· Perform 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.) immediately--do 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 mlmmlze 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 typically
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 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 source controls and treatment controls listed in the Recommendations.
Appropriate control measures are discussed in the Recommendations, in:
· Table 2: Summary of residential post-construction BMP selection
. Table 3: Summary of industrial post-construction BMP selection
· Table 4: Summary of commercial post-construction BMP selection
Additional sources of information that should be consulted for BMP selection include the California
Storm Water Best Management Practice Handbooks; the Bay Area Preamble to the California Storm

would like to make the following comments.
The District owns and manages the Tass~ara Creek Rcgional Park and segment of Regional
Trail within Tassajara Creek Regional Park (approximately 23 acres) across Tassajara Road
from the Quarry Lanc School. In t 998, the District commented on the Dr'cift EIR for Phase 1,
HIe initial phase of development for the QuaD)' Lane School. The EIR planned for 62,575
buihling sq. ft. as the planned full buildout ofthe private school. The District understands that
this projectis seeking approval for tho proposed development of two additional parcels (13.6
acres) cUITcntly It)cated will1in unincorporated Alameda County and tho annexation of those
parcels to the City of Dublin. This project proposes to increase development of classroom and
admiliistralive space to 66,685 sq. fi. for a total of 82,263 sq. ft vs. the original 62, 575 sq. fi
stated in the ElR. The project also proposes to add parking for 172 vehicles, recreational
facilities, and landscaping to accomlllodate 950 students and S5 staff. The 3.6 acre Kobold
property, located to the south of the school site for futuro development is proposed to be
irlcludcd in the am1exation action, since it is the intervening property between existing City
limits and the Quarry Lane School Site. A tributary of Tassajara Creek forms the sOllthem

Re: Quarry Lane School, Mitigated Negative Declaration
Dear Ms. Kinney:
Zone 7 has reviewed the above-referenced CEQA document submitted to
our office. Zone 7 is hereby submitting comments to the mitigated
negative declaration in the areas of Water Resources and Flood Control
as follows.
Flood Control:
Under Project Impacts and MitigatiQn Measures, Mitigation Measure 7a,
1. stormwater runoff from the site should also be evaluated as to whether
it will adversely impact the flood control facility, Tassajara Creek,
southwest of the proposed project site. The project developer shall
make arrangements satisfactory to the Dublin Director of Public Works
and Zone 7 that storm water flows can be safely accommodated.
Water Resources:
2.
When the facility is connected to the District's sewer, the existing
septic tank should be removed or decommissioned in such a way that it
is no longer a potential conduit for surface contaminants to reach the
groundwater table.
If the on-site well becomes obsolete subsequent to a municipal water
3. connection, then the well must be properly sealed or destroyed per
Alameda County Ordinance 73-68, which has also been adopted by the
City of Dublin.

Dear Mr. Peabody:
I am writing on behalf of my client, Mr. Robert Nielsen. Mr. Nielsen lives at 6407 Tassajara Road,
Pleasanton, 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.
1.
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.
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 II 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 II 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 a more central
3. location. In short, as opposed to the plan approved by the County of Alameda, the Api!i~~4ill1*:l~"'.j;;;,",wi".
client, he now has BOTH the playground and the Phase II building nearer to his hgme!" .,'... .

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 EIR, August 1998. The movement of the classroom building as well as the playground
area to the locations proposed to the City of Dubliri 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
me.re 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 n classroom building from the
6. southern edge of the parcel to the center ofthe parcel will of necessity result in a far greater amount
. of cut and fill operations. On behalfofmy 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.
If you have any questions, please feel free to contact the undersigned.
Vety truly yours,

Quarry Lane School- Phase IT Re-Assessment
Dear Dr. Arac:
This Jetter addresses noise issues for operation of the revised configuration of The Quarry Lane
Scboolat its future site on Tassajara Road in Dublin, Califomia. This assessment provides
a.dditional information with regard to the Phase n constrllction; the site plan has been revised and
thejurisdiction now falls with the City of Dublin. (Ref. Letters dated 9 December 1997 and 3 April
1998 [mis-dated 3 April 1.997]) This letter addresses three operational noise issues: the noise from.
the circulation of traffic to the parking lots, the noise from student~ at play at the
baseballlsoftbalVsoccer field or the tennis court, and the noise from the Phase J1 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.imately 90 ft from the property line. The Nielson residence
is situated on a hill overlooking Tassajara Road and haS a direct line of si.ght with the roadway to the
south. On the south side of the site is the Kobold Nursery, and residen.ce located in close proximity
to Tass8:.iara 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 lin.e. Undeveloped privately
owned land exists to the east of the school 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 ] 997 letter, sources of noise include heavy trucks, flyovers by
aircraft utilizing the nearby Livermore Municipal Airport, and heavy vehicle operation at the KoboJd

Quarry Lane School Noise Assessment
Nursery. The dominant noise source in the vicinity of the QLS site is the traffic on Tassajara Road.
In1997, the average daily traffic volume was 6400 vehicles with peak hour volumes of
approximately 550 vehicles.
Assessment 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 extend to the vicinity of the QLS. In
addition, widening of Tassajara Road to six lanes is currently underway south ofllie QLS site.
Traffic Noise
Traffic on Tassajara Road will be the primary contributor to the future noise cnvrronm.ent at the QLS
-and adjacellt 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 increa.se 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 on
the traffic projections provided by Abrams Associates, Phase IT of the QLS will require 2577 daily
trips, with 675 trips (in/out) OCCUlTIng during the AM peak hour. It is estimated that traffic associated
with the QLS will cause, at most, a noise level increase of 1 dBA ill the local area which is not
con~jdered significant. Furlhermore, traffic flow in and out of the school will be concelltrated only
during the morning peak hour (7:30 to 8:30 AM). Table 1 presents a summary of th.e projected
traffic noise levels during the morning peak hour.

the exterior areas simultaneously_ The site plan for the school indicates that play activities of the
students will be concentrated in on the play field (soccer, tennis, possibly softbal1/baseball)at the east
end of the site. Ambient noisc lcvels at this location will bc lowcr than othcr arcas since thc tcrrain
and school buildings will provide shielding from Tass~lara Road. BaScd on noise measurements
WIA has taken at playgrounds, average noise levels produced by approximately 100 children at play
may be in the r.ange of 65 to 70 dBA at approximately 1.00 ft from the center of the play area. Note
that this range applies to the equivalent noise level (L<!(() averaged over the measurement period (e.g.,
15 minutes). and that the noise level flucnlates over time and m.ay vary by approximately +/- 10
dBA. Maximum noi~e level~ occurring for ~hort 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 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 thefie.l.d) is projected to be approximate.ly 57 to 63dBA (LeQ) 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~'l) accounting for distance and ignoring shielding, and maximlllll
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 ignoling
shielding, and maximum levcls may reach 84 dBA. The Kobold rcsidcncc is approximately 520 ft
away from the play field and will he partially shielded by the topography of the Pr.oject. site. The
average noise levels at the Kobold residence produced at the play field arc prqjectcd to be
a.pproximately 56 to 62 dBA (Leq) accounting for distance and ignoring shielding, and maximum
levcls may reach 72 dBA.
To e!\timate 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@100 students in animated discussion). 2 lunch periods (45 minutes duration, 1 for
elementary@400 students and 1 for high school@IOO students), 5 gym class periods (50 minute
duration, 100 students each), and 1 after-school team sport (90 minutes ~uration, 50 students). Table
2 summarizes the projected range of noil>e levels for each of these events and the estimatcd. increase
in the CNEL is indicated.
With these projected levels. tbe playground noise will be audible to a person located outdoors at the
north and south property lines and at the Kobold andNieJson residences, however the ambient CNEL
will not be significantly increased since the projected levels are not high enough to affect the daily
a.verage, and the playground activities will occur for relatively short peliods of tillleduring the
daytime hours.

The Phase IT building will house the gymnasium, which will be the site of various school assemblies
and sporting events. At worst case, a capacity event in the gymnasium would contain the enlire
student population and school faculty. While the Phase II building does have windows on the east
an.d west facades, the gymnasium is separated from the exterior walls by a perimeter Jobby- 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 gymnasi urn t.o travel to the exterior of the building. We
have assumed that all such events would occur before 7 PM, with a duration np to 90 minutes, and
that the shielding provided by the building shell provides 10 to 20 dB noise reduction as compared

Quarry Lane School Noise Assessment
Conclusion
Based on this discussion, our analysis still indi.cates that the noise produced at the Quarry Lane
School is not cxpected to have an adverse effect on the existing or future noise environment at the
nearest receptors, and the tr.affic volume increase on Tassa.jara Road wiU be a considerably grcatcr
contributor to the environment. Traffic and play area acti vities are not expected to affcct the ambient
noise levels significantly, particularly since these activities will occur for relativcly short periods of
time and primarily during thc daytime hours.
Please let me know if you have any questions on this information.

My client and I have had the fUtther6ppoi'tUnity to discuss additional ways to address
the noise that m~ be genera~d by P_ IT of The Quarry Lane School.. The updated noise
study prepared by Wilson, Ihrig &;~~~; Inc. (dated August 14J 2000), City Staff
through the Staffhport. andtnePlanuing Oomnussion by way ofits recommendation to the
City Councill have already concludt.d t:hat the Sohool will not create significant noise
.impacts. However, in response tOith.~'coneemlii$ed by Mr. Nielsen (the neighbor who lives
to the north of the School) regarding the potential for noise, we would like to offer the
'following additional m~.
";~/
"';-
1. The Phase n plans locate the play tield further away from Mr. Nielsen's
residence then the plans for Phase I. According to the noise study, the play field is now
located approximately 560 ft. away from Mr. Nielsen's residenoe. The field has been
designed smaller 1hen Ii standard school play field. This substandard size preCludes the use
of this field for most organized athletic events and activities.
2. The School can min.imi2.e the use Of the play field by coordinating as many
llthlctic ovcnb and other school activities as pouible in the indoor gym. The nuise geuetalw
by the activities 'that occur in the gym will not be heard by Mr. Nielsen nor other indi:viduals
near the School.
3. The arrival and departure of the students. will be staggered in order to minimize
the noise levels that may occur. In addition, the, Sohool willstaggertb.e recess periods. As

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 .10ts, the noise from students at play at the
basebalVsoftballlsoc~et field. or the tennis court, and the noise from the Phase n building.
This revised report incorporates the results of recent noise measurements of the existing noise
environment and clarification of applicable impact criteria.
Noise Impact Criteda
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 CNEL 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 PM to 7 AM) to
account for the increased sensitivity of residents during those hours.
The City's Noise Ordinance addresses "unreasonable" noise, with guidelines for assessing the impact
of noise based on the time, duration and character. While the noise from the Quarry Lane School

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;x:ists to the east of the school 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 dominant noise source in the vicinity of the QLS site is the traffic on Tassajara Road.
In1997, 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
pecrOTXlled from November 1 to November 3. 2000. Location 1 was located in the parking lot 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 40ise levels obtained at the measurement
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 environmenlcurrently experienced at the nearby residences:
The elernentary school is currently in session. and these measurements include the typical daily noise
n"Om operation 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 dB. Thus, the noise measurements indicate that the existing noise environment near all residential
locations falls within the acceptable range for the City of Dublin.
Assessment 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 extend to the vicinity of the QLS (i.e.,
Dublin Ranch). In addition, widening of Tassajara Road to six lanes is cmrently underway south of
the QLS site.
Traffic Noise
Traffic on Tassajara Road will be the priIffi1I'Y 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. Tbls
increase is considered to be a significant impact independent of the operation of the QLS. Based on
the traffic projections provided by Abrams Associates, Phase n of the QLS will require 2577 daily
trips, with 675 trips (inlont) occurring duri:ng 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 concentrated only
during the morning peak: hour (7:30 to 8:30 AM). Table 1 presents a summary of the projected
tJ:affic noise levels during the morning peak hour.

Sports and Play Area
In addition to traffic, noise associated with play areas will be produced by operation of the QLS. The
QLS will ultimately enroll approximately 950 students although not all students will be a,t play in
the exterior areas simultaneously. The site plan for the school indicates that play activities ()f the
students will be concentrated in on the play Held (soccer, tennis, possibly softballlbaseball)at the east

end of the site. Ambient noise levels at this location will be lower than other areas since the terrain
and school buildillgs 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 me measurement period (e.g.t
15 minutes), and that the noise level fluctuates over time and may vary by approximately +/- 10
dBA. Maximum noise levels occuning for short time durations (Le.. less than I 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 300 to 400 students at any specified recess
period which will result in 5 to 6 dBA higher noise levels relative to the 100 smdent 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 apprmdmately 57 to 63 dBA (Leq) accounting for distance and
ignoring shielding, and maxlmumlevels may reach 73 dBA. The Nielson residence is approximately
560 ft away from the play field and.will be partially shielded by the [opography of the Project site.
The average uQise levels at the Nielson residence produced at the play field are projected to be
approximately 57 to 63 dBA (Leq) accounting for distance and ignoring shielding. and maximum
levels may ;reach 73 dBA.
At the southproperty 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 (Lcq) accounting for distance and ignoring shielding, andmaximum
levels may reach 72 dBA.

minutes duration, 1 for elementary@400 students and 1 for high school@ 100 students), 5 gym class
periods (50 minute duration, 100 students each), and 1 after~school team sport (90 nrinutes duration,
50 students). Table 2 summarizes the projected range of noise levels for each of these events.
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 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. (See below)
Gymnasium
The Phase llbuilding will house the gymnasium, which will be the site of various school assemblies
and sporting events. At worst case. a capacity event in the gymnasium would contain the entire
student population and school faculty. While the Phase n building does have windows on the east
and west facades.. the gymnasium is separated from the exterior walls by a perimeter lobby. At wot$t
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 assumed that all su.ch 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. Table 3 summarizes the projected and average noise levels.. from
gymnasium events.

To estimate the average noise levels for a typical school day) we have time-averaged the school
activities discussed above (traffic, play field use, gymnasium use) etc~). Using the estimated time
and duration of each event discussed above, the daily sound levels from Quany Lane School (Phase
II) have been tabulated to calculate me CNEL. Table 4 summarizes the existing and projected noise
levels with the school in full session.

3: This total noise level does not include the projected noise increase from higher traffic on Tassajara
Road .
4: This noise level is dominated by activities at the play field
Conclll$ion
Based on this discussion, our analysis indicates that at the nearest residences, the noise produced by
the Quarry Lane School will generate a total noise environment less than 65 CNEL (in combination
with the existing noise environment) and is not expected to have an adverse effect on the existing
or future noise environment at these residences. Similarly, the noise levels at the northern property
line will also remain below 65 CNEL. but at the southem property line closest to the proposed play
field, the CNEL will exceed 65. In this affected area, we'beHeve 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 business 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 activities will occur for relatively short periods of time and primarily 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.
Please let me know if you have any questions on this infonnation.

Subject:
Quarry Lane School- Phase n Re-Assessment, Alternative 2 (Revised)
Dear Dr. A:rac:
As requested, this letter addresses the projected relative change in noise levels for Alternative 2,
which places the new playfield approximately 25 ft to the southeast, at an elevation 10ft lower than
Alternative 1. This assessment has been revised to incorporate the results of the revised noise
assessment, also 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 June 7, 2000 for Alt. 1, 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 that there will be some shielding of playfield noise at the Nielson
residence provided by the 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 withinlO ft of the
same contour in Alternative 1. there is no difference in noise attenuation provided. No other
shielding is anticipated from the proposed topography.
The playfield location in Alternative 2 is projected to cau~e an increase in noise leveUess than 0.5
dBA at the Kobold residence. as compared to Alternative 1.
Based on this data, compared to Alternative 1, Alternative 2 provides no additional noise reduction
from theplayfield at the Nielson residence and increases slightly the playfield noise at the Kobold
residence. However, the CNEL noise levels are unchanged at both residences.
Please let me know if you have any questions on this information.
Very truly yours.
