CEQA Addendum for the Quarry Lane School Phase II Expansion
Project Location and Context
The project site is located on the east side of Tassajara Road approximately 1.75 miles
north ofi-580. The site address is 6363 Tassajara Road. The Assessor's Parcel Number is
985-0002-006-01.
The site encompasses 10 acres of land within the Dublin city limits that is currently used
as Phase ! of the Quarry Lane School, including a private elementary school for 200
students with 20 faculty and staff members. The adjacent property to the north is a single-
family home and ranch, within a Planned Development Zoning District. The adjacent
property to the south is a single-family home, landscape contracting business, and
landscape nursery, within a Planned Development Zoning District. The property to the
west is outside of the City limits and the property to the east is open space, which is
designated for rural residential uses as part of the Dublin Ranch Planned Development
Zoning District.
The project area is within the Eastern Dublin Specific Plan area. Exhibit 1 depicts the
location of the project area within the context of the larger City of Dublin area and
Exhibit 2 shows the detailed site location.
Proiect History and Previous CEQA Analyses
The project site was previously reviewed for annexation and development as part of the
Eastern Dublin EIR (SCH 91103604) prepared for the Eastern Dublin General Plan
Amendment and Specific Plan project. The EIR was certified by the City Council on
May 10, 1993. (Resolution 53-93, incorporated herein by reference). Numerous
mitigation measures were adopted, and continue to apply to the Quarry Lane School
project and project site as appropriate. Significant unavoidable impacts were also
identified; therefore, the City Council adopted a Statement of Overriding Considerations
upon approval of the Eastern Dublin project.
In April 1999, Alameda County approved a rezoning to the PD Planned Development
District to allow the first phase of the Quarry Lane School, consisting of a 15,600-square
-foot building for day care, preschool and elementary school grades with a maximum of
200 students. An Environmental Impact Report (Quarry Lane School, Environmental
Impact Report, the 2060th Zoning Unit, August 1998, SCH #97122109, incorporated
herein by reference) was certified by the County prior to approving the Phase I project.
The EIR included the full build out of the school, consisting of 62,575 square feet of
floor area for day care, preschool, elementary, middle and high school grades with a
maximum of 950 students and 55 faculty and staff members.
On December 19, 2000, the City of Dublin City Council approved a Planned
Development District Prezoning and Annexation application for Phase 2 of the Quarry
Lane School. The use, student population, building envelope, site layout, extent of
grading, and construction were studied as part of the application. The total project size

increased from the 62,575 square feet in the County's EIR to 82,263 square feet, but the
student population did not change. An Initial Study and Mitigated Negative Declaration
was prepared for the project that considered the following environmental factors:
aesthetics; biological resources; public services; utilities/service systems; cultural
resources; hydrology/water quality; noise; air quality; geology/soils; and
transportation/circulation. The adopted Mitigated Negative Declaration determined that
these impacts were less than significant with the mitigations incorporated into the project.
(Resolution 204-00, December 5, 2000, incorporated herein by reference.)
Project Description
The current project application consists of a Site Development Review, and minor
amendments to the approved Development Plan including a minor amendment to the
project building size, and a minor amendment to the number of parking spaces. In
addition, the project adds a second retaining wall with a height tapering up to six feet.
The purpose of the first minor amendment to building size is to allow a small increase in
the floor area of the building from the 66,685 to 70,289 square feet without increasing the
building envelope, the student population, faculty and staffpopulation, or the number of
classrooms. The number of classrooms will be reduced from 66 approved as part of the
Planned Development to 51 classrooms in the current project. The new floor area will be
used for additional storage rooms, mechanical rooms, and locker areas dispersed
throughout the project. This area is within the building dimensions approved as part of
the Planned Development in 2000, but not included in the floor area calculations at that
time.
The purpose of the second minor amendment is to allow a 10% reduction in the parking
required under the Planned Development project from 166 parking spaces to 149 parking
spaces while complying with the conclusions and recommendations of the Quarry Lane
Traffic and Circulation Study prepared by Abrams Associates, dated July 12, 2000. This
change was considered in conjunction with the project's change in number of classrooms.
The total number of classrooms approved as part of the Planned Development project
was 66. The current project provides 51 classrooms. The parking required pursuant to
City of Dublin Zoning Ordinance Chapter 8.76 would be reduced from 160 spaces to 130
spaces. An analysis of the Zoning Ordinance parking requirements for the SDR project is
attached as Exhibit B.
The third project amendment is the addition of a second retaining wall with height
tapering up to six feet, located below the slope of the hillside in the northern part of the
project area. The purpose of the wall is to widen the playing field area by one or two feet
to provide disabled access and to flatten the slope of the path along the northern part of
the project by one to four feet for disabled access. The amount of additional grading is
estimated to be less than 1% of the project grading. Furthermore, the grading required for
this wall is off-set by the reduction of grading further up the slope. The previous project
approved in the Planned Development District included grading to the 520-foot elevation.
According to the project plans and project engineer, the grading proposed as part of the
SDR project is limited to the 500-foot elevation, reducing the overall cut required.

Site Development Review
April 2004
Subsequent EIRs and Negative Declarations
City Staff reviewed the current project under the provisions found in Section 15162 of the
CEQA Guidelines, Subsequent EIRs and Negative Declarations. The intent of this
section is to identify the circumstances under which further environmental review would
be required. It states that agencies are prohibited from requiring further Environmental
Impact Reports unless "substantial changes" would require major revisions to the EIR.
This section provides certainty to applicants once in-depth review has already occurred,
the time for challenging the EIR has expired, and the issue is whether or not
circumstances have changed to the point that the E1R process must be repeated,i
Pursuant to Section 15162, when an EIR has been certified or a negative declaration
adopted for a project, no subsequent EIR shall be prepared for that project unless the lead
agency determines, on the basis of substantial evidence in the light of the whole record,
one or more of the following:
(1) Substantial changes are proposed in the project which will require major
revisions of the previous EIR or negative declaration due to the involvement of new
significant environmental effects or a substantial increase in the severity of
previously identified significant effects;
(2) Substantial changes occur with respect to the circumstances under which the
project is undertaken which will require major revisions of the previous EIR or
Negative Declaration due to the involvement of new significant environmental effects
or a substantial increase in the severity of previously identified significant effects; or
(3) New information of substantial importance, which was not known and could not
have been known with the exercise of reasonable diligence at the time the previous
EIR was certified as complete or the Negative Declaration was adopted, shows any of
the following:
(21) The project will have one or more significant effects not discussed in the
previous EIR or negative declaration;
(B) Significant effects previously examined will be substantially more severe than
shown in the previous EIR;
(C,) Mitigation measures or alternatives previously found not to be feasible would
in fact be feasible, and would substantially reduce one or more significant effects
of the project, but the project proponents decline to adopt the mitigation measure
or alternative; or
(D) Mitigation measures or alternatives which are considerably different from
those analyzed in the previous EIR would substantially reduce one or more
significant effects on the environment, but the project proponents decline to adopt
the mitigation measure or alternative.
Quarry Lane School, PA 99-064
Site Development Review
April 2004
City Staff determined that the changes to the project consisting of a small increase in
useable floor area, reduction in parking, and addition of a small retaining wall would not
require major revisions to the previous EIRs or Mitigated Negative Declaration because
the changes would not have new significant environmental effects or a substantial
increase in the severity of previously identified significant effects. City Staff reviewed
the environmental factors that were considered in the prior reviews and determined that
because the building envelope, building location, extent of grading and student
population were unchanged, the impacts and appropriate mitigations were the same; no
new mitigations were required. Furthermore, City Staff determined that no change in
circumstances would result in new significant environmental effects or a substantial
increase in the severity of previously identified significant effects because no new
circumstances have developed since the EIRs were certified and the Mitigated Negative
Declaration was adopted.
Addendum to an EIR or Negative Declaration
City Staff reviewed the project under the provisions found in Section 15164 of the CEQA
Guidelines, Addendum to an EIR or Negative Declaration. This section provides clear
authority for an addendum as a way of making minor corrections in EIRs and negative
declarations without recirculating the EIR or negative declaration,ii
Pursuant to Section 15164, the lead agency shall prepare an addendum to a previously
certified EIR if some changes or additions are necessary but none of the conditions
described in Section 15162 calling for preparation of a subsequent EIR have occurred.
(b) An addendum to an adopted negative declaration may be prepared if only minor
technical changes or additions are necessary or none of the conditions described in
Section 15162 calling for the preparation of a subsequent EIR or negative
declaration have occurred.
(c) An addendum need not be circulated for public review but can be included in or
attached to the final EIR or adopted negative declaration.
(d) The decision making body shall consider the addendum with the final EIR or
adopted negative declaration prior to making a decision on the project.
(e) :t brief explanation of the decision not to prepare a subsequent EIR pursuant to
Section 15162 should be included in an addendum to an EIR, the lead agency's.
findings on the project, or elsewhere in the record. The explanation must be
supported by substantial evidence.
City Staff determined that the Site Development Review, changes to the building floor
area, reduction in the number of parking spaces, and addition of a retaining wall did not
necessitate the preparation of a subsequent Environmental Impact Report, Mitigated
Negative Declaration or Negative Declaration for the reasons outlined in the section

above. This addendum to the adopted EIRs and Mitigated Negative Declaration has been
prepared to support the determination that the changes to the project would not have new
significant environmental effects or a substantial increase in the severity of previously
identified significant effects. The following report reviews the changes in light of the
environmental factors considered in the prior environmental reviews.

Site Development Review
April 2004
Statement of Overriding Considerations
The City Council previously balanced the benefits of the Eastern Dublin Specific Plan
project approvals against the significant and potentially significant adverse impacts
identified in the Eastern Dublin EIR. The Alameda County Board of Supervisors also
weighed the benefits of the project against the potentially significant unavoidable impact
of construction noise. The impacts that apply to the Quarry Lane School project
amendments and the benefits of the project are discussed in Exhibit A, attached.

EXHIBIT A
STATEMENT OF OVERRIDING CONSIDERATIONS
1. General. Pursuant to CEQA Guidelines section 15093, the City Council of the City of Dublin adopted a Statement
of Overriding Considerations for those impacts identified in the Eastern Dublin EIR as significant and unavoidable.
(Resolution 53-93, May 10, 1993.) The City Council carefully considered each impact in its decision to approve
urbanization of Eastem Dublin through approval of the Eastern Dublin General Plan Amendment and Specific Plan
project. The Community Development Director is currently considering a Site Development Review application for
the Quarry Lane School property in Eastern Dublin. The Quarry Lane School project proposes to expand the current
school of 200 students to a total of 950 students in a new building, including additional parking, and creation of a new
sports field. The impacts of the expansion, including the construction of the new building and sports field, were
studied in the Quarry Lane School EIR, certified by the County of Alameda, and in a Mitigated Negative Declaration
certified by the City of Dublin as part of the annexation and Planned Development approvals for the property. After
the Planned Development project was approved, Site Development Review and Conditional Use Permit applications
were submitted by the applicant to complete final architecture and design considerations, pursuant to City
regulations. An Addendum document has been prepared that reviews the changes that were made to the project as
part of these applications; the changes are collectively referred to herein as the project "amendments".
The City Council adopted a Statement of Overriding Considerations with the original land use approvals for
urbanization of Eastern Dublin. Pursuant to a recent court decision, the Planning Commission hereby adopts specific
overriding considerations for the Quarry Lane School project amendments. ~
The Planning Commission finds that many of the unavoidable environmental effects identified in the Eastern Dublin
EIR that are applicable to Quarry Lane School site will be substantially lessened by mitigation measures adopted with
the original approvals by the City and County, by the environmental protection measures adopted through the Quarry
Lane School Planned Development and Annexation approvals, and by the environmental protection measures
adopted through the Quarry Lane School project amendments approval, and the related Conditions of Approval, to be
implemented with the development of the project as amended. Even with mitigation, the Planning Commission
recognizes that the implementation of the project carries with it unavoidable adverse environmental effects as
identified in the Eastern Dublin EIR and the Quarry Lane School EIR. The Planning Commission specifically finds
that to the extent that the identified adverse or potentially adverse impacts for the Quarry Lane School project
amendments have not been mitigated to acceptable levels, there are specific economic, social, environmental, land
use, and other considerations that support approval of the Project.
2. Unavoidable Siqnificant Adverse Impacts. The following unavoidable significant environmental impacts
identified in the Eastern Dublin EIR for future development of Eastern Dublin and in the Quarry Lane School EIR
apply to the Quarry Lane School project amendments:
Eastern Dublin EIR
Land Use Impact 3.1IF. Cumulative Loss of Agricultural and Open Space Lands; Visual Impacts 3.8/B; and,
Alteration of Rural/Open Space Character. Although considerable development has occurred south of the Quarry
Lane School area, the site was agricultural grazing land prior to construction of the current school, and the site has
some remaining open space character. Future development of the Quarry Lane School site will contribute to the
cumulative loss of open space land.
~ "...public officials must still go on the record and explain specifically why they are approving the later project despite its significant
unavoidable impacts." (emphasis original.) Communities for a Better Environment v. California Resources Aqency 103 Cal.App. 4th 98,
(2002).
1
Traffic and Circulation Impacts 3.3/B, 3.3/F. 1-580 Freeway, Cumulative Freeway Impacts: The Traffic Study
prepared for the Quarry Lane School project and the Dublin Transit Center EIR update cumulative impacts to the I-
580 and 1-680 freeways from development in Eastern Dublin. While city street and interchange impacts can be
mitigated through planned improvements, transportation demand management, the 1-580 Smart Corridor program,
and the extension of Fallon Road to Tassajara Road and other similar measures, mainline freeway impacts continue
to be identified as unavoidable, as anticipated in the Eastern Dublin EIR. Future development on the Quarry Lane
School site will incrementally contribute to the unavoidable freeway impacts.
Community Services and Facilities Impact 3.4/S. Consumption of Non-Renewable Natural Resoumes and Sewer,
Water; and Storm Drainage Impact 3.5/F, H, U. Increases in Energy Usage Through Increased Water Treatment,
Disposal and Operation of Water Distribution System: Future development of the Quarry Lane School project will
contribute to increased energy consumption.
Soils, Geology, and Seismicity Impact 3.6/B. Earthquake Ground Shaking, Primary Effects: Even with seismic
design, future development of the Quarry Lane School project could be subject to damage from large earthquakes,
much like the rest of the Eastern Dublin planning area.
Air Quality Impacts 3.11/A, B, C, and E: Construction of the Quarry Lane School project will contribute to cumulative
dust deposition, construction equipment emissions, mobile and stationary source emissions.
Quarry Lane School EIR
Noise Impacts, Chapter IV.G: Using the Model Noise Ordinance allowable level of 75 dBA, the Quarry Lane School
construction operations could potentially produce an adverse response by adjacent resident within 300 feet. Despite
the temporary nature of the effect, this would constitute a significant noise impact. Application of mitigation measures
would not fully reduce these impacts to a level of insignificance.
3. Overriding Considerations. The City Council previously balanced the benefits of the Eastern Dublin project
approvals against the significant and potentially significant adverse impacts identified in the Eastern Dublin EIR. The
Planning Commission now balances those unavoidable impacts that apply to future development on the Quarry Lane
School site against its benefits, and hereby determines that such unavoidable impacts are outweighed by the benefits
of the Quarry Lane School project as further set forth below.
A. The Quarry Lane School has a history of high academic achievement. High-quality schools are a
complement to existing and planned residential land uses in the vicinity. An educated future workforce is an
asset to the community.
B. The School site contains a large area of open space and undeveloped hillside. The open area will contribute
to the aesthetics of the community and offer a rural component to the area.
C. The School site is easily accessible as it is located 1.75 miles north of 1-580 on a planned arterial street.
D. The School offers after-school care for students.
Therefore, the Quarry Lane School Phase II project as amended provides important benefits to the City of Dublin,
Alameda County and the Bay Area, and the benefits of the project outweigh any remaining adverse impacts that may
remain after the adoption of Mitigation Measures and other project components.
