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. Because the proposed project is generally based
on the land use designations, circulation patterns etc. assigned to the project by the City of
Dublin General Plan and Eastern Dublin Specific Plan, the Initial Study relies on a Program EIR
certified by the City in 1993 for the Eastern Dublin General Plan Amendment and Specific Plan
(the "Eastern Dublin General Plan Amendment and Specific Plan Environmental Impact Report,
State Clearinghouse No. 91103064). That EIR, also known in this EIR as the "Eastern Dublin
EIR," evaluated the following impacts: Land Use, Population, Employment and Housing, Traffic
and Circulation, Community Services and Facilities, Sewer, Water and Storm Drainage, Soils,
Geology and Seism city, Biological Resources, Visual Resources, Cultural Resources, Noise, Air
Quality and Fiscal Considerations.
Some of the potentially significant impacts identified in the Eastern Dublin EIR apply to the
proposed project and, therefore, the adopted mitigation measures also apply and are included in
this Initial Study by reference, However, as indicated in the environmental checklist, conditions
related to agricultural resources, biological resources, noise, public services (schools),
Transportation and Circulation and Utilities and Service Systems may have changed since the
Eastern Dublin EIR was certified.

Project Location and Context
The project area consists of 187.7 acres ofland located in an unincorporated area of Alameda
County generally bounded by the Alameda/Contra Costa line to the north, Camp Parks Reserves
Forces Training Area to the west, Tassajara Road to the east and the existing Dublin City limit
line to the south. Exhibit 1 shows the regional location of Dublin. Exhibit 2 shows the project
area in relation to the remainder of the City of Dublin; Exhibit 3 shows the proposed
reorganization (annexation) area and current property ownerships. Exhibit 4 shows the proposed
Stage 1 PD-Planned Development proposal for the Wallis Ranch property within the proposed
reorganization area. The entire project area is located within the City of Dublin's General Plan
Planning Area and Sphere of Influence and consists of three different parcels each with a
different owner.
City of Dublin
Initial Study/Wallis Ranch Annexation
PA 02-028
Page 2
February 2003
The topography of the site ranges from relatively steep, rolling hills in the north and westerly
portions of the project area to a relatively flat elevation in the approximate center of the project
area transitioning to Tassajara Creek and adjoining areas that generally forms the easterly
boundary of the project area. Tassajara Creek and its immediate environs are wooded with oaks
and other native vegetation.
The largest property comprising the project area, the Lin parcel, is currently used for cattle
grazing with a rural residence, storage yard and associated outbuildings scattered throughout the
site. One of the two remaining properties (Bragg) is undeveloped and one single family residence
has been constructed on the Sperfslage parcel.
In 1994 the City of Dublin adopted a General Plan Amendment and a Specific Plan, which
addressed long-tenn development of approximately 4,200 acres of land east of the central portion
of Dublin. The entire project site is located in the westerly portion of that General Plan
Amendment area. The proposed project would implement land uses and other programs included
in the Eastern Dublin Specific Plan. At build-out, this portion of the project's approximately 188
acres has been planned for a mixture of Low Density Residential, Medium Density Residential,
Medium High Density Residential, Neighborhood Park, Neighborhood Square, Neighborhood
Commercial, and Open Space in the Eastern Dublin Specific Plan.
Project Background and Description
All of the subject property is located within the unincorporated area of Alameda County. The
proposed project consists of: an Amendment to the Eastern Dublin General Plan and Specific
Plan, a Stage I Development Plan application to the City of Dublin requesting a pre-zoning of
the site in accordance with the City's General Plan and Eastern Dublin Specific Plan, as would
be amended by this application; annexation of the project area to the City of Dublin and the
Dublin San Ramon Services District (DSRSD); and execution of a Pre-Annexation Agreement
between the City of Dublin and the project proponents/property-owners.
General Plan/Specific Plan Amendment
An Amendment has been proposed to the Eastern Dublin General Plan and Eastern Dublin
Specific Plan for the Lin property, also known as Dublin Ranch West. Although the basic
structure of land uses as currently shown on the Eastern Dublin Specific Plan would remain as
presently planned, the following three major changes have been requested by the applicant:
· Land uses presently shown adjacent to Tassajara Creek in the project area, which inClude
a Neighborhood Park, Neighborhood Square and Neighborhood Commercial area, all
comprising 9.9 acres of land, are proposed to be converted to Open Space. This action
would be consistent with a Biological Opinion recently published by the United States
Fish and Wildlife Service (July 1, 2002), restricting use of Tassajara Creek as open space
for approximately 53 acres of land along a 5,200 linear foot reach of Tassajara Creek
commencing from the confluence of Tassajara Creek and the "Northern Drainage."
· Allowing the potential conversion of a presently planned Elementary School site
presently shown on the Specific Plan to Medium-High Density residential uses. This
portion of the requested Amendment will be based on a determination that the planned
elementary school site is no longer needed by the Dublin Unified School District for
education purposes and that adequate school sites can be provided elsewhere in the
Eastern Dublin area.

· Other minor changes to land use patterns within the Lin Property based on newer and
more refmed topographic conditions of the site.
Overall, there would be a potential increase of up to 277 dwelling units, a decrease of 10,454
square feet of neighborhood commerci~, deletion of an elementary school site and an increase of
9.9 acres of open space at full buildout of proposed land uses on the Lin property compared with
the existing Specific Plan land use designation. Exhibit 3 shows proposed land uses under the
requested Specific Plan/General Plan Amendment and Stage 1 PD-Planned Development
rezoning for the Wallis· Ranch.
No changes to existing General Plan or Specific Plan land use designations are proposed for the
Bragg or Sperfslageproperties included in the project area. Proposed land uses for these
properties are shown on Table 1, below.

Stage 1 Planned Development (Prezoning)
The applicant for the Lin Property (Wallis Ranch) has requested approval of prezoning.
Prezoning is an action to indicate what city zoning will take effect once the annexed property
becomes part of the city. The City of Dublin uses a Stage 1 Planned Development (PD) under
City of Dublin Page 4
Initial Study/Wallis Ranch Annexation February 2003
P A 02-028
/
Chapter 8.32 of its zoning ordinance to prezone property in accordance with the City's General
Plan and, in this case, Eastern Dublin Specific Plan land use designations. Under the City's
zoning ordinance a Stage 1 development plan must establish: a plan of proposed land use by type
and density of use; the maximum number of dwelling units and commercial/office/industrial
areas; a master landscape plan; and a preliminary development phasing plan. Project proponents
will also apply for a Stage 2 PD for site-specific zoning and development plap. approval. City
approval of a Stage 2 development plan must be received to complete the PD zoning process.
Historic feature
Potential historic resources exist on the project site. According to the applicant, the property
owner has taken steps to minimize damage to a school building and has offered to donate the
structure to an appropriate historical group for purposes of preservation and public access. It is
anticipated that, prior to development of this portion of the project site, the school building will
be moved to another site and refurbished. The applicant has-performed historic resource surveys
which will be used to assess the potential impact with the follow-on environmental analysis.
Infrastructure
As part of the proposed development portion of the project, project developers would construct
all major roadways and public infrastructùre such as water, wastewater, recycled water, and
storm drainage facilities required to support future development. Major roadways would be
constructed to and through the project area with project proponents potentially utilizing
assessment districts, the City's Traffic hnpact Fee program" or other appropriate financing
mechanisms to help fund construction.
Grading activities would occur within the project area to accommodate planned land uses, roads
and utilities, although the amount of grading will not be established until the Stage 2 Planned
Development when detailed site and grading plans are developed. Water, sewer and recycled
water services would be provided to the area by DSRSD, once the proposed reorganization
(annexation) is complete, in accordance with plans formulated by DSRSD and the City's General
Plan and Eastern Dublin Specific Plan. The project developers would continue the extension of
these services throughout the project area as it is developed.
Water distribution mains are planned to be located in all major streets. Construction of water
storage reservoirs are not anticipated to be part of this project, although a water storage tank is
proposed to be constructed near the project area. Sewer service for the project would be provided
through connection to the DSRSD sewer system. When and where available, DSRSD would
provide recycled water for irrigation purposes, reducing the need for potable water. All water and
sewer facilities would be constructed to DSRSD standards.
The storm drainage system for proposed development on the Wallis Ranch would flow into
Tassajara Creek, located in the westerly portion of the project area and then flow south into the
Arroyo Mocho for ultimate discharge into San Francisco Bay. Future development of the Wallis
Ranch will require additional hydrology and drainage studies as mandated by the eastern Dublin
Specific Plan.
The City of Dublin's inclusionary zoning ordinance requires that 12.5% of a project's dwelling
units must be affordable to very low, low and moderate income households. Compliance could
consist of constructing the required number of ii:1clusionary units or paying an in-lieu fee to the
City, or a combination of both. The project proponents will be required to comply with the
City of Dublin
Initial Study/Wallis Ranch Annexation
PA 02-028

ordinance, although the specific method generally would not be determined until the Stage 2 PD-
Planned Development rezoning and related subdivision maps are reviewed.
The project applicants indicate that land uses and infrastructure would be phased over a number
of years to ensure that roads and other infrastructure facilities would be available to support land
uses as they are needed.
Proposed Reorganization (annexation)
The project site is contiguous with the City of Dublin to the west, lies within DUblin's Sphere of
Influence and within the Sphere of Influence of the Dublin San Ramon Services District
(DSRSD). The City's General Plan and the Eastern Dublin Specific Plan conte~plated the
eventual annexation and development of the project site in accordance with the land use
designations, programs and policies of each Plan.
Exhibit 4 shows the boundary of the pr~posed reorganization.
Similarly, the project area is within the expected service area of DSRSD and all of DSRSD's
master plans for the provision and distribution of water, wastewater service, and recycled water
include the annexation of, and service to, the project area. Because the water, wastewater, and
recycled water services are provided to the City of Dublin by DSRSD, the City and DSRSD have
concurred in policy that their boundaries and Spheres of Influence will be coterminous (except
for that portion of DSRSD's service area which extends to portions of Contra Costa County).
Hence, annexation of the area to the City also requires annexation of the area to DSRSD to
provide needed urban services as assumed in the City's long term plans for the area.
Pre-annexation AgreementlDevelopment Agreements
The City requires that the project proponents and property owners enter into pre-annexation and
development agreements with the City. Pre-annexation agreements encourage project proponents
and the City to meet certain mutual obligations while the area proposed for annexation is
proceeding through entitlement processes and ensure that the proposed project will not be a
ñnancial burden to the City. Development agreements vest development approvals for a
specified period of time so that developers of large, time extensive projects have the ability to
construct such projects in a time frame and under mutual obligations beneficial to the City and
the project proponent. Issues typically addressed in development agreements include, but are not
limited to: density and intensity of land use; timing of development; financing methods and
timing of infrastructure; determination of traffic, noise, public facility and other impact fees; and
obligations for construction of streets and roads. Development agreementS would be part of a
later City action generally occurring with City approval of a Stage 2 Planned Development, Site
Development Review and tentative subdivision map(s).

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 ahd
the previous Negative Declaration certified for this project by the City of Dublin adequately
addresses potential impacts and mitigates impacts to a less-than-significant level.
_ 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.
-.1L I fmd 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 proposed project.

Evaluation of Environmental Impacts
1) A brief explanation is required for all answers except "no impact" answers that are
adequately supported by the information sources a lead agency cites in the parenthesis
following each question. A "no impact" answer is adequately supported if the referenced
information sources show that the impact simply does not apply to projects like the one
involved (e.g. the project falls outside a fault rupture zone). A "no impact" answer should
be explained where it is based on project-specific factors as well as general factors (e.g.
the project will not expose sensitive receptors to pollutants, based on a project-specific
screening analysis).
2) All answers must take account of the whole action, including off-site as well as on-site,
cumulative as well as project-level, indirect as well as direct, and construction as well as
operational impacts.
3) "Potentially Significant Impact" is appropriate if there is substantial evidence that an
effect is significant. If there are one or more "potentially significant impact" entries when
the determination is made, an EIR is required.
4) "Negative Declaration: Potentially Significant Unless Mitigation Incorporated" implies
elsewhere the incorporation of mitigation measures has reduced an effect from
"potentially significant effect" to a "less than significant impact." The lead agency must
describe the mitigation measures and briefly explain how they reduce the effect to a less -
than significant level.

XVll. Earlier Analyses
This Initial Study is being prepared to determine whether an earlier EIR (the EIR prepared for
the Eastern Dublin General Plan Amendment and Specific Plan, State Clearinghouse No.
91103064) may be used to evaluate the proposed project pursuant to CEQA Guidelines (Section
15063 (c)(7).
a) Earlier analyses used. Identify earlier analyses and state where they are
available for review.
Portions of the environmental setting, project impacts and mitigation measures for this Initial
Study refer to environmental information contained in the 1992 Eastern Dublin General Plan
Amendment and Specific Plan Environmental Impact Report (State Clearinghouse No.
91103064), hereinafter referred to as the Eastern Dublin EIR. The Eastern Dublin EIR is a
Program EIR which was prepared for the Eastern Dublin General Plan Amendment and Specific
Plan of which this Project is a part. It was certified by the Dublin City Council on May 10, 1993.
As part of the certification the Council adopted a Statement of Overriding Considerations for the
following impacts: cumulative traffic, extension of certain community facilities (natural gas,
electric and telephone service), regional air quality, noise and visual.
The Eastern Dublin EIR contains a large number of mitigation measures which apply to this
Project and which would be applied to any development within the Project area. Specific
mitigation measures identified in the certified Eastern Dublin EIR for potential impacts are
referenced in the text of this Initial Study.
Since certification of the Eastern Dublin EIR, several changes in circumstances in which the
Project will take place have occurred and which could effect the impacts and/or mitigations
analysis of the Project. Such changes in circumstances include, but are not limited to: 1)
additions of species to the California and/or Federal Endangered or Threatened Species Lists; 2)
continued development in the Tri-Valley area and beyond with potential-changes in commute
patterns and traffic intensities, which also may affect air quality and noise within or on the
project area; 3) changes in California law regarding annexations (i.e., adoption of AB 2838)
which may affect the designation of portions of the project site as prime agricultural soils; and 4)
changes in the provision and distribution of some public services (schools) and public utilities
(water, wastewater, storm drainage and gas and electricity).
Pursuant to CEQA Guidelines Section 15162 and 15163, this Initial Study is intended to identify
the potential for any new or substantially increased significant impacts on Or of the Project which
were not evaluated in the Eastern Dublin EIR and which would require additional environmental
reVIew.
