Recitals
1. In response to a proposal for residential development of
the Dublin Ranch property, the City of Dublin undertook the Eastern
Dublin Study to plan for the future development of the eastern
Dublin area.
2. The City Council and Planning Commission conducted three
joint public study sessions and three workshops relating to
planning issues in eastern Dublin.
a. The April 18, 1990, study session considered a land
use concept report containing four land use scenarios and the
consistency of each land use concept with existing general plan
policies. Alternative #4 was considered the preferred land use
concept for environmental study by informal consensus.
b. The August 22, 1990, study session considered
Alternative ~4 and a fifth concept (based on the 1986 annexation
agreement with Alameda County). The "Town Center" concept, types
of streets, location and types of parks were discussed.
c. The November 15, 1990, workshop solicited comments
from the public regarding the existing and desired life style
qualities in Dublin and what the public wanted to see in a new
community.
d. The December 6, 1990, workshop continued w~th a
similar discussion of desired types of commercial development and
discussed circulation systems and parks and open space.
e. The December 18, 1990, workshop presented a
preliminary conceptual land use plan. Input was received on the
transit spine, location of civic'center, types of residential uses,
location of commercial uses, the concentration of high density
residential uses, and jobs/housing balance.
1
f. The February 14, 1991, study session considered a
land use plan that incorporated comments made at the three
workshops and included a discussion of major issues, such as the
location of a high school, connection to existing Dublin, size of
streets and types of parks.
3. With the .identification of a preferred alternative on
February14, 1991, the city prepared a Draft General Plan Amendment
for approximately 6,920 acres to plan for future development of a
mixed use community of single- and multiple-family residences,
commercial uses (general commercial, neighborhood commercial,
Campus office and industrial park), public and semi-public
facilities (in=luding schools), parks and open space.
Draft General Plan Amendment
4. The Draft General Plan Amendment, dated May 27, 1992,
designates the proposed general distribution and general location
and extent of the uses of Eastern Dublin for residential,
commercial, industrial, public, open space and parks, and other
categories of public and private uses of land.
5. The Draft General Plan Amendment includes a statement of
standards of population density and standards of building inter~ity
for Eastern Dublin.
6. Pursuant to the provisions of State Planning and Zoning
Law, it is the function and duty of the Planning Commission of the
City of Dublin to review and recommend action on proposed
amendments to the City's General Plan.
7. The Planning Commission held a duly noticed public hearing
on the Eastern Dublin Draft General Plan Amendment on October 1,
1992, which hearing was continued to October 6, 1992, October 12,
1992, and October 15, 1992.
8. Based on comments received during the public hearing,
related text revisions, dated December 21, 1992, were made to the
Draft General Plan Amendment and were reviewed by the Planning
Commission on December 21, 1992.
9. The Draft General Plan Amendment was reviewed by the
Planning Commission in accordance with the provisions of the
California ~nvironmental Quali~y Act through the preparation and
review of an Environmental Impa=t Report. On December 21, 1992,
by Resolution No. 92-060, the Planning Commission recommended
certification of the Final Environmental Impact Report.
10. On December 21, 1992, the Planning Commission, after
considering all written and oral testimony submitted atthe public
hearing, adopted of Resolution No. 92-061, recommending City
Council adoption of the Draft General Plan Amendment, as revised
December 21,'1992.
Draft Specific Plan
11. The Draft Specific Plan, dated May 27, 1992, implements
an approximately 3,328-acre portion of the Eastern Dublin General
Plan Amendment by providing a detailed framework, including
policies, standards and implementation programs, for evaluation of
development projects proposed in the portion of eastern Dublin
covered by the Draft Specific Plan.
12. Pursuant to State Law, the Eastern Dublin Draft Specific
Plan was prepared and reviewed in the same manner as a general plan
amendment.
13. The Planning Commission held a duly noticed public
hearing on the Eastern Dublin Draft Specific Plan on October 6,
1992, which hearing was continued to October 12, 1992, and October
15, 1992.
14. Based on comments received during the public hearings,
related text revisions, dated December 21, 1992, were made to the
Draft Specific Plan and were reviewed by the Planning Commission
on December 21, 1992.
15. The Draft Specific Plan was reviewed by the Planning
Commission in accordance with the provisions of the california
Environmental Quality Act through the preparation and review of a
Final Environmental Impact Report. On December 21, 1992, by
Resolution No. 92-060, the Planning Commission recommended
certification of the Final Environmental Impact Report.
16. On December 21, 1992, the Planning Commission, after
considering all written and oral testimony submitted att he public
hearing, adopted Resolution No. 92-062, recommending City Council
adoption of the Draft Specific Plan, dated May 27, 1992, as revised
December 21, 1992.
Council Public Hearinq
17. The City Council held a duly noticed public hearing on
the Eastern Dublin Draft General Plan Amendment and Draft Specific
Plan on January 14, 1993, which hearing was continued to January
21, 1993, February 23, 1993, March 30, 1993, and April 27, 1993.
18. On April 27, 1993, the City Council, by Resolution No.
45-93, voted to refer Alternative 2: Reduced Planning Area
("Alternative 2") with modifications back to the Planning
Commission for its recommendation, pursuant to Government Code
section 65356.
3
19. The Planning Commission held a public hearing on May 3,
1993, to consider Alternative 2 with modifications and has reported
back to the City Council by Planning Commission Resolution No. 93-
013.
20. The City Council considered all written and oral
testimony submitted at the public hearing and all written testimony
submitted prior to the public hearing and the recommendation of the
Planning Commission as set forth in Planning Commission Resolution
Nos. 92-061, 92-062 and 93-013.
21. On May 10, 1993 the Council held duly noticed a public
hearing to hear testimony regarding the Planning Commission's
recommendation as set forth in Planning Co~mission Resolution No.
93-013.
22. On May 10, 1993, the CitYCouncil adopted Resolution No.
51-93, certifying the Addendum to the Draft EIR and the Final
Environmental Impact Report ("Final EIR") as adequate and complete.
The Final EIR identified significant adverse.environmental impacts
which can be mitigated to a level of insignificance through changes
or alterations in the project. Therefore, pursuant to CEQA,
findings adopting the changes or alterations are required and are
contained in this resolution. Some of the significant impacts
cannot be mitigated to a level of insignificance and a statement
of overriding considerations istherefore required pursuant to CEQA
and is also contained in this resolution.
23. Upon consideration of the land use and environmental
effects of the project, as described in the Final EIR, the Council
has determined to adopt Alternative 2, as described in the Final
EIR, with certain modifications which are described in the Addendum
to the Draft EIR ("Alternative 2 With Modifications"). Alternative
2 With Modifications reduces land use impacts, does not disrupt the
existing rural residential community in Doolan Canyon, potentially
reduces growth-inducing impacts on agricultural lands, reduces
certain traffic impacts to a level of insignificance, produces less
demand for infrastructure, reduces the noise impacts for Doolan
Road to a level of insignificance and will have a positive fiscal
impact on the City.
24. Alternative 2 was considered by the Planning Commission
at its hearings, in testimony at the public hearings, in staff
reports presented to the Commission at its hearings, in the EIR
reviewed by the Planning Commission at its hearings and in its
deliberations.
25. Alternative 2 With Modifications includes several
substantial modifications to Alternative 2, as Alternative 2 is
described in the Draft EIR. Although several of these
modifications were considered by the Planning Commission at its
hearings, the Planning Commission has considered Alternative 2 With
Modifications and has reported back to the Council with its
recommendation regarding Alternative 2 With Modifications. The
Council has determined to follow the Planning Commission's
recommendation as set forth in its Resolution No. 93-013, except
with respect to the width of the Transit Spine and with the
addition of the phrase "or other appropriate agreements" on page
160 of the Draft Specific Plan (§ 11.3.11 first sentence).
Findinqs/Overriding Considerations~
Mitiqation Monitorinq Pro,ram
26. Public Resources Code section 21081 requires the City to
make certain findings if the City approves a project for which an
environmental impact report has been prepared that identifies
significant environmental effects.
27. Section 15093 of the State CEQA Guidelines requires
adoption by the City Council of a statement of overriding
considerations if the Council approves a project which will result
in unavoidable significant effects on the environment.
28. Public Resource Code section 21085 and section 15092 of
the State CEQA Guidelines require the City to make certain
determinations if it approves a project which reduces the n~her
of housing units considered in the environmental impact report.
29. The Final EIR for the Eastern Dublin General Plan
Amendment and Specific Plan identifies certain significant adverse
environmental effects.
30. Certain oft he significant adverse environmental effects
can be reduced to a level of insignificance by changes or
alterations in the project.
31. Certain of the significant adverse environmental effects
cannot be mitigated to a level of insignificance.
32. The Council has selected Alternative 2 identified in the
Final EIRwithmodifications described in the Addendum tot he Draft
EIR, reducing the number of housing units for much property from
the project as reviewed by the Final EIR for the Eastern Dublin
General Plan Amendment and Specific Plan.
33. Public Resources Code section 21081.6 requires the City
to adopt a reporting or monitoring program for changes in a project
or conditions imposed to mitigate or avoid significant
environmental effects in order to ensure compliance during project
implementation.
34. Government Code section 65300 authorizes a city council
to adopt a general plan for land outside its boundaries which in
the Planning Commission's judgment bears relation to its planning.
35. The Planning Commission has considered whether land
outside the City's boundaries bears relation to the City's
planning.
36. The City has referred Alternative 2 With Modifications
tot he Alameda County Airport Land Use Commission ("ALUC") pursuant
to Public Utilities Code section 21676 (b). The City has not
received a determination from theALUC. The 60-day time period for
the ALUC to make a determination has not yet run.

Section 2
F~ND~NGS CONCERNING S~GNIF~CANT ~MP~CTS
AND KIT~GAT~ONMEASURES
Pursuant to I~blic Resources Code section 21081, the City
Council hsreby makes the following findings with respect to the
Project's~ potential significant environmental impacts and means
for mitigating those impacts. Findings pursuant to section
21081, subdivision (c), as they relate to "project alternatives,-
are made in Section 3.
Section 3.1.-- Land Use
IMPACT 3.1/F. c~mulatlve Loss of Agricultural a~d 'Open Space
Lands. Agricultural grazing land and open space in Alameda and
Contra Costa counties will be converted to urban uses by proposed
projects such as DoughertyValley, Tassajara Valley, North
Livermore, and Eastern Dublin. Because it would result in the
urbanization of a large area of open space, the proposed Project
Would contribute to this cumulative loss of agricultural land and
open space in the Tri-Valley area. This is considered a signifi-
cant unavoidable cumulative impact. Response to Comments ("RC")
# 34-9.
Finding. No mitigation measures are proposed to reduce this
impact to a level of insignificance. Therefore, a Statement
of overriding Considerations must be adopted upon approval
of the Project.
Rationale for Finding. The tota~ amount of open space
withinthe RPA that will be urbanized will be cumulatively
significant, in light of numerous other open space areas
within'the region that is also anticipated for urbanization.
IMPACT 3.1/G, Potential Conflicts with Land Uses to the West.
The Parks Reserve Forces Training Area ("C~mp Parks") is located
due west ofthe Specific Plan area. Existing and future Army
training activities, such as the use of high velocity weapons and
helicopters, could result in noise and safety Gonflicts with
adjacent open space and single-family residential areas of the
Specific Plan. The extent of future army activity is unknown and
LThe "Project" is Alternative 2 described in the DEIR at
pages 4-9 through 4-14 with the modifications described in the
May 4, 1993 Addendum to the EIR. Alternative 2 calls for
development in the Reduced Planning Area (the portion of eastern
Dublin within its sphere-of-influence) (hereafter "RPA").

the Army has not yet completed its Camp Parks Master Plan. DEIR
page 3.1-13.
Mi~qa~ion Measure 3.1/1.0. The City of Dublin should
coordinate its planning activities with the Army to achieve
compatibility with adjacent Camp Parks land uses, to solve
potential future conflicts, and to reconcile land use incom-
patibilities. The City should consult with the Army for any
specific development proposals within the RPA. DEIR pages
3.1-13, -22.
F~ndina~ Changes or alterations have been required in, Or
incorporated into, the Project that avoid or substantially
lessen ~the significant effect identified in the Final EIR.
Rationale for Finding. Coordinated planning activities will
allow the City and Army to identify potential noise and
safety impacts before they occur and will allow specific
mitigation measures, including redesign, to be incorporated
into development in the Project Area.-
Section ~.3 -- Traffic and CircUlation
When a mitigation measure referenced in this section requires
development~projects within the RPA to pay for a proportionate
cost of regional transportation programs and/or traffic and
circulationiimprovements, the proportion shall be as determined
by regional(transportation studies, such as the current study by
the Tri-Valley Transportation Council.
IMPACT $.$/A. 1-580 Freeway, Tassajara-Fallon. Year 2010 growth
without the'[Project would cause cumulative freeway volumes to
exceed Level of Service E on 1-580 between Tassajara Road and
Fallon Road. DEIR pages 3.3-21 (as revised), 5.0-3.
Mitiaation Measure 3.3/1.0. Caltrans, in cooperation with
local jurisdictions, could construct auxiliary lanes on 1-
580 between Tassajara Road and Fallon Road to create a total
of ten lanes, which would provide Level of Service D opera-
tions, consistent with the Caltrans Route Concept Report for
1-580. DEIR pages 3.3-21 (as revised), 5.0-3.
Findina. Approval of the construction of the auxiliary
lanes, and cooperation by jurisdictions other than the City
of DubLin, are within the responsibility and jurisdiction of
other Public agencie~ and not the City of Dublin. Such
action~ can and should be taken by other agencies. If
taken,[such actions would avoid or substantially lessen the
significant effect identified in the Final EIR.
! 14 \ea si;dub \find ( 4 ) 2
Rationale for Finding. This mitigation measure provides
acceptable Level of Service D operations during peak hours
on the .. freeway.
IMPACT 3.3/B. 1-580 Freeway, 1-680 to Hacienda° Year 2010
growth with the Project would cause 1-580 between 1-680 and
Dougherty Road to exceed Level of Service E. This is also a
significant cumulative impact. DEIR pages 3.3-21 (as revised),
4-11, 5.0-3.
Mitiqation ~easure 3.3/2.0. Consistent with Specific Plan
PoliCY 5-21 , all non-residential projects with 50 or more
employees in the RPA shall participate in a Transportation
Systems Management (TSM) program to reduce the use of single
occupant vehicles through strategies including but not
limited to encouraging public transit use, carpooling, and
flexible work hours. DEIR pages 3.3-21 (as revised), 5.0-
3. :
Mitiqa~ion Measure 3.3/2.1. All projects within the RPA
area shall contribute a proportionate share of the costs of
regional transportation mitigation programs, as determined
by regional transportation studies. Such regional miti-
gationl, programs may include enhanced public transit service
and/or upgrading alternate road corridors, to relieve demand
on 1-580 or 1-680. DEAR page 3.3-21 (as revised).
Finding. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact might not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for Findinq. Approval of Alternative 2 reduces to
a leve~ of insignificance the impact on 1-580 between
Doughe~ty Road and Hacienda Drive. DEIR page 4-11. The TSM
program strategies will reduce single car occupancy, thereby
reducing the number of cars expected to use the subject
stretc~ of 1-580. Regional actions may focus not only on
reducing auto use by reducing single occupant vehicles, but
also on increasing Project area road capacities through
2 This policy appears in the Eastern Dublin Specific Plan,
which plan applies only to the identified Specific Plan area.
The provisions of this policy provide useful mitigation outside
the Specific Plan area as well. Therefore, the EIR and these
findings adopt these provisions for the entire RPA. Hereinafter,
those Specific Plan goals, policies, and action programs whose
provisions are similarly adopted for the RPA throughout these
findings will be indicated by an asterisk.

construction of routes providing convenient alternatives to
1-580 and 1-680. Given the overall expected increase in
traffic, however, these measures are not sufficient to
reduce ,the cumulative impacts on 1-580 between 1-680 and
Doughe.~y Road to insignificance.
IMPACT 3.3/C.. 1-580 Freeway, Tassajara-Fallon-~/rwa]~. Year 2010
growth with~'the Project would cause freeway volumes to exceed
Level of SerVice E on 1-580 between Tassajara Road and Airway
Boulevard. ~This is also a significant cumulative impact. DEIR
page 3.3-21 :.i (as revised) , 5.0-3.
Mitiqation Measure 3.3/3.0. The City shall coordinate with
Caltrans and the city of Pleasanton to construct auxiliary
lanes on 1-580 between Tassajara Road and Airway Boulevard.
All projects within the RPA shall contribute a proportionate
share of the costs of these improvements. DEIR pages 3.3-
2~. (as revised), 5.0-3; RC ~7-6
Findinq. Changes or alterations have been required in, or
incorporated into the Project that avoid or substantially
lessen the significant effects identified in the Final EIR.
Freeway construction actions are within the ultimate res-
ponsibility and jurisdiction of Caltrans, 'who can and should
take s~ch actions. If taken, such actions would avoid or
substantially lessen the significant effect identified in
the Final EIR.
Rationale for FindinG. The auxiliary lanes wi11 provide
sufficient additional capacity on 1-580 to provide Level of
Service D between Fallon Road and Airway Boulevard, and
Level Of Service E between Tassajara Road and Fallon Road.
Both Level of Service D and E are acceptable during peak '
freeway hours. DEIR pages 3.3-2, -18. Development in the
RPA will be required to contribute its fair share to the
auxiliary lane improvements so that when such improvements
are needed, they will be provided by new development
generating the need. State law authorizes the City to enter
into a cooperative agreement with Caltrans to make the
freeway improvements (see, e.q., Streets & Highways Code
SS 113.5, 114).
IMPACT 3.3/~. 1-680 Freeway, North of 1-580. Year 2010 gr.ow~.
with the Pr.~.ject would cause freeway volumes to exceed Level cz
Service E o4 1-680 north of the 1-580 interchange. This is also
a slgnlf~ca~_t cumulative impact. DEIR page 3.3-22, 5.0-4.
Mitiqa%"ion Measure 3.3/4.0.. All projects in the RPA shall
contriDute a proportionate share of the costs of Caltrans'
planned improvements at the 1-580/I-680 interchange, in-
cluding a new two-lane freeway-to-freeway flyover with

revised) (see also page 3.3-17 (as revised)).
(as ~ '
Finding. Changes or alterations have been required in, or
incorporated into the Project that .avoid or substantially
lessen ithe significant effects identified in the Final EIR.
Freewa~ interchange improvement actions are within the
responsibility and. jurisdiction of Caltrans, who can and
should ~take such actions. If taken, such actions would
avoid or substantially lessen the significant effect
identified in the Final EIR.
Rationale for Findinq. The expected interchanges and
related improvements will provide sufficient additional
capacity on 1-680 to provide Level of Service D north of the
1-580 interchange. Development in the RPA will be required
to contribute its fair share to the interchange and related
improvements so that when such improvements are needed, they
will be provided by new development generating the need.
LM~ACT 3.3/7. C,~ulative ~reeway Impacts. Cumulative bui%dout
with the Project would cause additional freeway sections, In-
cluding I-5~0 east of Airway Boulevard, and the segment of 1-580
between Dougherty and Hacienda to exceed level of mervice E.
DEIR pages 3.3--22 (as revised), 5.0-4.
Mitiqation Measure 3.3/5.0. The Project shall contribute a
proportionate share to the construction'of auxiliary lanes
(for a total of 10) on 1-580 east of Airway Boulevard, for
implementation by Caltrans. The City shall coordinate with
other local jurisdictions to require that all future de-
velopment projects participate in regional transportation
mitigation programs as determined by the current Tri-Valley
Transportation Council study. DEIR pages 3.3-22 (as re-
vised), 5.0-4.
Finding. Changes or alterations have been required in, or
incorporated into, the Project. Actions by other agencies
and Caltrans to implement this mitigation measure are within
the responsibility and jurisdiction of those other agencies
and no~ the City of Dublin. Such actions can and should be
taken ~y the other agencies. However, even with these
change~ the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted.
Rationale for Findinq. The auxiliary lanes will provide
sufficient additional capacity to provide acceptable level
of service on part of 1-580 widening to ten lanes is
consistent with the Route Concept Report. DEIR page 3.3-22
(as revised). Regional transportation mitigations can

reduce cumulative impacts through measures to decrease
single occupant vehicle use and increase public transit use
to further decrease traffic impacts. However, even with
these improvements, part of 1-580 (between 1-680 and
Hacienda Drive) will still be beyond acceptable LOS E. DEIR
pages 3.3-20, 3.3-21 (as revised), 4-11.
LMP~CT 3.3/F. Dougherty Road and Dublin Boulevard. Year 2010
development with the Project would cause Level of Service F
operations at the intersection of Dougherty Road with Dublin
Boulevard. iDEIR page.3.3-25.
Mitiqa{ion Measure 3.3/6.0. The City of Dublin shall
monitor the intersection and implement construction of

would require the City to build grade-separated interchanges
on Dublin Boulevard and/or establish alternate routes to
redistribute traffic flow. All projects in the RPA shall
contribute a proportionate share of improvement costs. DEIR
pages 3.3-27 (as revised), 5.0-4.
Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact might not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted'upon approval of the Project.
Rationale for Finding. Regional transportation programs
will attempt to reduce the amount of future traffic and
associated impaots. Even with these efforts, however, the
cumulative traffic impacts on Dublin Boulevard might not be
reduced to insignificance.
I~P~CT 3.3/N. Cumulative Impacts on Tassajara Road. Cumulative
buildout with the Project would cause Level of Service F opera-
tions at the intersections of Tassajara Road with Fallon Road,

residents. DEIR page 3.3-28.
Finding. Changes or alterations have been required in, or
incorporated into the Project. Some of the transit service
coordination actions are within the responsibility and
jurisdiction of Bart and LAVTA agencies and not the City of
Dublin, Such actions can and should be taken by those
agencies. If taken, such actions would avoid or
substantially lessen the significant effect identified in
the Final EIR.
Rationale for_ Findina. The mitigations provide for
expansion of existing transit systems to meet Project
demand, not only on the local level through LAVTA but also
on a local and regional level through BART.
IMPACT 3.3/P. Street Crossings for ~edestrians and Bic]~cles.
Pedestrians <and bicycles would cross major streets with high

Mitiqation Measure 3.3/16.1. The City shall locate
pedestrian and bicycle paths to cross major arterial streets
at signalized intersections. DEIR page 3.3-29.
Finding. Changes or alterations have been required in, or
incorporated into the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Placing a major bicycle/pedestrian
path along Tassajara Creek and using trails along other
stream corridors allows bicycles and pedestrians to avoid
traveling on major streets with their high traffic volumes.
Where the paths must cross a major arterial street, re-
quiring the crossing at a signalized intersection minimizes
path and traffic conflicts by stopping traffic on a regular
basis to let path travelers cross the street safely.

Mitigation Measure 3.4/5.0. As part of the development
review process for residential and non-residential projects,
the Police Department shall review development projects'
design and circulation for visibility, security, safety,
access, and emergency response times and any other police
issues. DEIR pages 3.4-2 to -3.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. The five mitigations identified will
ensure that additional police will be hired and~that other
administrative measures will be employed to provide adequate
protection for Project area residents. Police Department'
input into design of Project development will insLlre that
police~services are efficiently provided.
IMPACT 3.4/C. De~m~nd for Increased Fire Services. Buildout of

Rationale for Findinq. New fire facilities will be
constructed to meet the needs of Project residents; DRFA
input into Project design features will enable additional
and efficient provision of fire services. The wildfire
management plan should further limit the Project fire
protection impacts by reducing the risk of wildfires.
IMPACT 3.4/D. Fire Response to OutlyingAreas. Based on DRFA's
preliminary~locations for new fire stations, the northern-most
portions of the RPA would be outside the District's standard

of new parks and facilities, the increased demand for new park
and recreation facilities resulting from buildout of the Project
would not be met, resulting in deterioration of the City's park
provision standard and of the City's ability to maintain existing
services and facilities. This is also a significant cumulative
impact. DEIR pages 3.4-16, 5.0-5.
~tigation Measures 3.4/20.0 to 24.0. General Plan
Amendment Guiding Policies A, B, and G and Implementing
Policy D require the City of Dublin to provide and maintain
parks and related facilities adequate to meet Project and
citywide needs and in conformance with the city's Park and
Recreation Master Plan 1992. Implementing Policy K
specifically requires dedication and improvements for the 20
parks designated in the RPA with collection of in-lieu fees
as required by City standards. DEIR pages 3.4-16 to -17,
Mitigation Measures 3.4/25.0 to 27.0. Sufficient parkland
shall be designated and set aside in the RPA to~ satisfy the
City's~Park and Recreation Master Plan 1992 and. its park
provision and phasing standards. DEIR pages 3.4-17, 5.0-5.
Mitigation Measure 3.4/28. The City shall implement
Specific Plan Policies 6-1 to -6* to establish large,
continuous natural open space areas with convenient access
for users, and adequate access for maintenance and manage-
ment; to preserve views of designated open space areas; and
to establish a mechanism for open space ownership, manage-
ment, and maintenance. (*Specific Plan provisions adopted
throughout RPA.) DEIR page 3.4-18 to -19.
Findinq. Changes or alterations have been required in, or
incorpgrated into, the Project that avoid or substantially
lessen~the significant effect identified in the Final EIR.
Rationale for Findinq. These mitigations provide added new
parks and facilities to meet increased demand from Project
residents, and require compliance with phasing plans in the
Park and Recreation Master Plan 1992, to ensure that new
parks and facilities construction will keep paoewith new
residential construction.

IMPACT 3.4/L. Park Facilities Fiscal Impact. Acquisition and
improvement of new park and recreation facilities may place a
financial strain on existing City of Dublin revenue sources
unless adequate financing and implementation mechanisms are
designed. DEIR page 3.4-18.
Mitiqation Measures 3.4/20.0 to 31.0. Pursuant to Specific
Plan Policy 4-29* and Action Program 4N,* the City shall
ensure that development provides its fair share of planned
open space; for example, through in-lieu fees under the
City'slparkland dedication ordinance. Pursuant to Specific
Plan Program 4M,* the city shall develop a Parks Imple-
mentation Plan identifying phasing, facilities priorities
and location, and design and construction responsibilities.
(*Specific Plan provisions adopted throughout RPA.) DEIR
page 3~4-18.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. These mitigations ensure that needed
park facilities will be provided by developers at the time
of development, thereby avoiding the use of existing revenue
sources to build new parks for Project area residents.
IMPACT 3.4/M, N. Impact on Regional Trail System and Impact .on
Open Space Co~-ections. Without adequate provisions~ for trail
easements and without adequate design and implementation, urban
development.along stream corridors and ridgelands would obstruct
formation of a regional trail system and an interconnected open
space system. DEIR page 3.4-18 to -19.
Mitigation Measure 3.4/32.0. P~rsuant to General Plan
Amendment Guiding Policy H,* establish a trail system with
regional and subregional connections, including a trail
along the Tassajara Creek corridor. (*Specific Plan
provisions adopted throughoutRPA.) DEIR page 3.4-19.
Mitiqation Measures 3.4/23.0 and 33.0 to 36.0. Pursuant to
General Plan Amendment Guiding Policy I, Implementation
Policy D, Specific Plan Policies 6-1,* 6-3,* Action Program
40,* and consistent with the City's Parks and Recreation
Master Plan 1992, use natural stream corridors and major
ridgelines as the basis for a trail system with a conti-
nuous,~integrated open space network, emphasizing convenient
user access, pedestrian and bicycle connections between
developed and open space areas, and developer dedication of
ridget0P and stream corridor public access easements.

Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Establishing a Project area trail
system incorporating planned regional connections contri-
butes to development of a regional trail system and allows
the trail planning to be considered and incorporated into
individual Project area developments in the RPA. By .
requiring that open space and trail planning be based on
continuous physical features such as stream corridors and
ridgelines, and that public access be provided along these
features, these mitigations avoid a disconnected open space
system.~
IMPACT 3.4/0, P. In=rease~ Solid Waste Production and Impact on
S011~ Waste Disposal Fa¢ilitles. Increased population and
commercial land use will cause a proportional increase in the
total projected a~ount of solid waste and household hazardous
waste generated by the city of Dublin. This increase creates the
need for additional capacity, personnel, and vehicles to dispose
of the wastes. It can create public health risks from improper
handling. The increased solid waste and household hazardous
waste generated by the Project may accelerate the closing
schedule for Altamont landfill unless additional capacity is
developed or alternate disposal sites are identifie~. This
impact on the Altamont landfill is also a potentialiy significant
cumulative impact. DEIR pages 3.4-21 to -22, 5.0-6.
Mitiqation Measures 3.4/37.0 to 40.0. Pursuant to Specific
Plan Action Program 8K* and other EIR mitigations, adopt a
Solid Waste Management Plan for the RPA, including waste
reduction programs such as composting and curbside and other
Collection of recyclables. Include goals, objectives, and
progrsms necessary to integrate with the diversion targets
of the City's Source Reduction and Recycling Element and
Household Hazardous Waste Element. New development in the
RPA shall demonstrate adequate available landfill capacity
for anticipated wa~te~. (*Specific Plan provisions adopted
throughout RPA.) DEIR pages 3-4.22 to -23, 5.0-6.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. These mitigations minimize the
amount~of solid waste production and related needs and risks
through compliance with AB 939 solid waste planning.
Reducing the amount of Project-generated waste will also
avoid an accelerated closing schedule for the Altamont
landfiI1. In addition, these mitigations require that new
11 & \ eastdub\£i~4 ( & ) 21
develoDment anticipate and Provide for adequate waste
disposal before the development is approved.
IMPACT 3.4/Q. De. and for Utility Extensions. Development of the
Project site will significantly increase demand for gas, electric
and telephone services. Meeting this demand will require
construction of a new Project-wide distribution system. This is
a significant growth-inducing impact. DEIR pages 3.4-24, 5.0-14
to -15.
Mitiqation Measures. None proposed. DEIR page 3.4-2.4.
Findinq. No changes or alterations are available to avoid
or substantially lessen this impact. Therefore, a Statement
of Overriding Considerations must be adopted upon approval
of the'.Project.
IHPACT 3.4/R. Utility Extension Visual and Biological impacts.
Expansion of electrical, gas, and telephone lines could adversely
affect visual and biological resources if not appropriately
sited. DEI~ page 3.4-24.
Mitigation Measures 3.4/41.0 to 44.0. Pursuant to Specific'
Plan Action Program 8L* and other identified mitigation
measures, development within the RPA must document the
availability of electric, gas, and telephone service and
must place utilities below grade or, preferably, underground
and routed away from sensitive habitat and open space lands.
A development project service report shall be.reviewed by
the City prior to improvement plan approval., f-Specific
Plan provisions adopted throughout RPA.) DEIR page 3.4-24
to -25.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoidor substantially
lessen~i~the significant effect identified in the Final EIR.
Rationale for Findinq. Undergrounding utilities will avoid
visual~effects by placing the utility extensions Where they
cannot~be seen. Routing the utility extensions away from
sensitive habitat and open space areas will avoid impacts on
biological resources by avoiding the resources themselves.
IMPACT 3.4/8. Consumption of Non-Renewable Natural Resottrces.
Natural gas and electrical service would increase consumption of
non-renewable natural resources. DEIR page 3.4-25.
Mitiqation Measures 3.4/45.0 to 46.0. Major developers in
the Project area shall provide demonstration projects on
cost-effective energY conservation techniques including but
not limited to solar water and space heating, landscaping
114\eastd~\~i~d (4)
22
for water conservation, and shading. All development
projects in the RPA shall prepare an energy conservation
plan as part of their proposals. The plan shall demonstrate
how site planning, building design, and landscaping will
conserve use of energy during construction and long term
operation. DEIR page 3.4-25.
Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for Findinq. Through the demonstration projects,
developers can educate themselves and Project residents
about available and feasible techniques to reduce
consumption of energy resources. Requiring energy
conservation plans forces both developers and the City to
actively consider various techniques to reduce energy
consumption and to build those techniques directly into the
Project. These actions cannot, however, fully mitigate the
impact.
IMPACT S.4/~. De, an4 for Increased Postal Service. The Project
will increase the demand for postal service. DEIR page 3.4-26.
Mitiqa~ion Measures 3.4/47.0 to 48.0. Pursuant to Specific
Plan POlicy 8-10 and Action Program SM, the City shall
encourage the U.S.P.S. to locate a new post office in the
Eastern Dublin town center. DEIR page 3.4-26; RC ~ 15-37.
Findina. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Actions to site a new post office within the town center are
within the ultimate responsibility and jurisdiction of the
USPS and not the City of Dublin. Such actions can and
should be taken by the USPS. If taken, such actions would
avoid or substantially lessen the significant effect
identified in the Final EIR.
Rationale for Findinq. A post office conveniently located in
the to~n center area will provide postal service to meet the
Project generated demand.
IMPACT $.4/U. Demand for Increased Librar~ Service. Without
additional ~ibrary facilities and staff, the increase in
population resulting from the Project would adversely affect
existing library services and facilities DEIR page 3.4-27.

Mitiqation Measures 3.4/49.0 to 51.0. Pursuant to Specific
Plan Policy 8-11- and Action Program 8N* and other identi-
fied mitigation measures, the city shall encourage and
assist the Alameda County Library System to provide adequate
library service in eastern Dublin, considering such factors
as location, phasing, and funding of needed library
services. (*Specific Plan provisions, adopted throughout
RPA.) DEIR pages 3.4-27 to -28; RC 215-38.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen.the significant effect identified in the Final EIR.
Actions to provide library facilities are within the
ultimate responsibility and jurisdiction of the Alsmeda
County~Library system and notthe city of Dublin. Such
actions can and should be taken by the Alameda County
Library System. If taken, such actions would avoid or
substantially lessen the significant effect identified in
the Final EIR.
Rationale for Findinq. Providing library services to the RPA
will meet Project generated demand. Planning how and when
to provide those services will ensure that they are
efficient and convenient to the maximum number of users.

IMPACT 3.5/~. Indirect Impacts Resulting from the Lack of a
Wastewater Service Provider. Although Specific Plan Policy 9-4
(page 127) calls for the expansion of DSRSD's service boundaries
to include the Specific Plan area, the Project does not provide
for wastewater service to areas in the RPA outside the specific
plan area. iThis could result in uncoordinated efforts by future
developers in this area to secure wastewater services. DEIRpage
Mitigation Measure 3.5/1.0a. Pursuant to Specific Plan
Policyi~9-4,* the City shall coordinate with DSRSD to expand
its service boundaries to encompass the entire RPA.
(*Specific Plan provisions adopted throughout RPA.) RC ~

taken by the DSRSD. If taken, such actions would avoid or
substantially lessen the significant effect identified in
the Final EIR.'
114 \ eastdub\find ( 4 )
24
Rational for Finding. Expanding DSRSD's service
boundaries to include the entire RPA will ensure that
securing wastewater services will be coordinated
through one agency.
IMPACT 3.$/B. Lack of a Wastewater Collection System. Estimated
wastewater flow for the RPA is 4.6 MGD; however, there currently
is no wastewater collection system adequate to serve the Project
area. DEIR page 3.5-5.
Mitiqation Measures 3.5/1.0 to 5.0. Pursuant to Specific
Plan Action Programs 9P,* 9I,* 90,* 9M,* and 9N,* all
development in the RPA shall be connected to public sewers
and shall obtain a "will-serve" letter prior to grading
permits; on-site package plants and septic systems shall be
discouraged. The City shall request that DSRSD update its
collection system master plan to reflect Project area
proposed land uses, with the cost of the plan to be borne by
future development in the RPA. Ail wastewater systems shall
be designed and built in accordance with DSRSD standards.
(*Specific Plan provisions adopted throughoutRPA.) DEIR

Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the'Final EIR.
Rationale for Findinq. These mitigations will provide a
wastewater collection system adequate to meet Project
generated demand, and will ensure the system meets design
and construction standards of DSRSD.
ZMPACT3.5/C. Extension of a Sewer Trunk Line with Capacity to
Serve New Developments. Construction of a wastewater collection
system could result in development outside the RPA that would
connect to the Project's collection system. This is also a
potentially significant growth-inducing impact. DEIR pages 3.5-
6, 5.0-15.
Mitiqa{ion Measure 3.5/6.0. The proposed wastewater system
shall be sized only for the RPA area. DEIR pages 3.5-6, 4-
11, 5.0-15.
FindinG. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen:the significant effect identified in the Final EIR.
Rationale for Finding. By sizing the planned wastewater
collection system only to serve the RPA, growth inducing
impacts on lands outside that area are avoided.

Rationale for Findinq. The required investigation will allow
development to be phased to ensure there are adequate
wastewater facilities available to meet Project, generated
demand. The requirement of a "will-serve" letter will
insure that adequate wastewater facilities wilt..exist for
all new development. If capacity is not available, DSRSD
will not issue a will-serve letter. RC $32-22.'
IHP~CT 3.5/E. Put=re Lack of Wastewater Treatment Plant
Capacity. Development of the Project require an increase in
wastewater treatment plant capacity within DSRSD to adequately
treat the additional wastewater flows to meet discharge
standards. This is also a potentially significant cumulative
impact in that increased demand on area wastewater treatment .
facilities exceeds current remaining capacity. DEIR page 3.5-7

Mitiqation Measures 3.5/7.1, 8.0, 9.0. Pursuant to Specific
Plan Policy 9-6* and mitigations identified in the EIR,
ensure~that w~stewater treatment and disposal facilities are
available for future development in the RPA through
compliance with'DSRSD's master plan to fund, design, and
construct wastewater treatment plant expansion once export
capacity is available (unless TWA approves export of raw
wastewater, in which case DSRSD's wastewater treatment plant
expansion will not be necessary). Also, development project

Dublin~ Such actions can and should be taken by other
agencies. However, even if such actions are taken, this
impact~.will not be avoided or substantially lessened.
TherefOre, a Statement of Overriding Considerations must be
adopted upon approval of the Project.
Rationale for Findinq. Use of energy efficient treatment
system~ and plant operations will reduce the amount of
energy!use but these actions cannot fully mitigate the
impact.
IMPACT 3.5/G. Lack of Wastewater Current Disposal Capacity. The
increase in wastewater flows from the Project and other sub-
regional development will exceed available wastewater disposal
capacity until additional export capacity is developed. This is
also a significant cumulative impact. DEIR page 3.5-8, 5.0-6.

able, DSRSD will not issue a will-serve letter,..RC #32-22..
IHPACT 3.5/H. Increase in Energy Usage Through Increased
Wastewater Disposal. Development of the Project will result in
increased wastewater flows and will require increased energy use
for disposal of wastewater; more specifically, for (1) pumping
raw wastewater to CCCSD for treatment under the TWA proposed
project; and/or (2) operation of an advanced treatment and
distribution system for recycled water. DEIR page 3-5.9.

encourage off peak pumping to the proposed TWA export
system. The City shall plan, design, and construct the
Project recycled water treatment system for energy efficient
operation including use of energy efficient treatment
systems, optimal use of storage facilities, and pumping at
off peak hours. DEIR pages 3.5-10 to -11.
Findinq. Such actions are within the responsibility and
jurisdiction of other public agencies and not the City of

Rationale for Findinq. Engineering redundancy will minimize
the risk of pump station system failure; providing emergency
power generators will ensure that any system failure which
does occur will- be short lived, thereby avoiding't_he effects
of such failure. RC ~32-28.
IMPACT 3.S/J. Pump Station Noise and Odors. The proposed TWA
wastewater pump stations could generate noise during their
operation and could potentially produce odors. DEIR page 3.5-10.
Mitiqation Measure 3.5/18.0. TWA's pumps and motors will be
designed to comply with local noise standards and will be.
provided with odor control equipment. DEIR page. 3.5-10.

throughout RPA.) DEIR page 3.5-17; RC ~14-4.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Actions to expand DSRSD's service boundaries are within the
responsibility and jurisdiction of the DSRSD and not the
City of Dublin. Such actions can and should be taken bythe
DSRSD. If taken, such actions would avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. Annexation to DSRSD and connection
to its~'water distribution system will eli~inate~the need for
development projects to drill their own wells .and will
therefore avoid the risk of groundwater overdrafting.
IKPACT 3.5/Q. In=tease in Demand for Water. Estimated average
daily Water,demand for the RPA is 6.4 MGD, which demand could
exceed available supply. This is also a potentially significant
cumulative impact in that ongoing urban development in the Tri-
Valley is resulting in a cumulative increase in water demand at a
time when water supplies and delivery are uncertain. DEIR page
3.5-18, 5.0-7 to -8.
Mitiqation Measures 3.5/26.0 tO 31.0. Pursuant to Specific
Plan Action Programs 9A* and 9B,* the City shall require
development projects in the RPA to include water conserva-
tion measures within structures as well as in public and
other improvements. Require developments to comply with
DSRSD and Zone 7 reco~mmendations for developing and using
recycled water. Pursuant to other EIR mitigations,
implement Zone 7 and DSRSD water supply and water quality
improvements and interconnect Project area water systems
with existing surrounding water systems for increased
reliability. (*Specific Plan provisions adopted throughout
RPA.) !iDEIR pages 3.5-18 to -19; 5.0-9; RC ~13-9, 32-43.

Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Some adtions to improve water supply and quality are within
the responsibility and jurisdiction of other public agencies
and not the City of Dublin. Such actions should be taken by
such other agencies. If taken, such actions can and would
avoid Or substantially lessen the significant effect
identified in the Final EIR.
Rationale for..Finding. Through required water conservation
and water recycling mitigations, the Project reduces the
magnitude of the impact by reducing the demand for water
using recycled water for irrigation reduces the estimated
average daily water demand in the RPA to 5.5 MGD. (RC
#32.52.) The remaining water quality and water supply
mitigations will result in an increased water availability
from Zone 7 and DSRSD to meet Project generated demand.
IHPACT 3.5/R. ~ddltlonal Treatment Plant Capacity. The increase
in water demand through development of the Project will require
an expansion of existing water treatment facilities in order to
deliver safe and potable water. DEIR page .3.5-19.
Mitiqation Measures 3.5/32.0 to 33.0. Implement Zone 7's
planned water treatment system improvements. DSRSD shouted
constr~/ct two new chlorination/fluoridation stations at the'
two proposed Zone 7 turnouts to eastern Dublin, with the
constrUction phased west to east as anticipated in the
General Plan Amendment. DEIR page 3.5-19.
Findin=. Such actions are within the responsibility and
jurisdiction of other public agencies and not the City of
Dublin. Such actions can and should be taken by other
agencies. If taken, such actions would avoid or sub-
stantially lessen the significant effect identified in the
Final EIR.
Rationale for Findinq. Proposed water treatment system
improvements will insure that Project water supply meets all
applicable water quality requirements.
~HPACT $.5/S. Lack of a Water Distribution S~stem. -There
currently i~ no water distribution system to provide water
service for !'the RPA. DEIR page 3.5-20.
Mitigation Measures 3.5/34.0 to 38.0. Pursuant to Specific
Plan Policy 9-1- and Action Programs 9C,* 9D,* 9E,* and 9G,*
the City shall provide an adequate water supply system with
related improvements and storage facilities for all develop-
ment, in compliance with applicable DSRSD standards. The

33
City shall request that DSRSD update its water system
masterplan to reflect the proposed land uses, and require a
"will-~erve" letter from DSRSD prior to grading permits for
any Project area development. The City shall encourage the
proposed water system to coordinate and combine with
existimg neighboring water systems. (*Specific Plan
provisions adopted throughout RPA.) DEIR page 3.5-20.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. These mitigations will provide a
water distribution system adequate to meet Project-generated
demand, and will insure the system meets design and
construction standards of DSRSD.
T~PACT 3.5/T. Indu~emen~ of substantial G~o~ch ~u~ Concentration
of Population. The proposed water distribution system will
induce growth.: in the Project area and has been sized to poten-
tially acco~odate the Dougherty Valley Development to the north.
However, if!~.DSRSD does not provide water to the Dougherty Valley
Development~~ the pipes will be sized to only accommodate the RPA.
The impact is also a potentially significant growth-inducing
impact. DEIR page 3.5-20, 5.0-15, RC ~32-41, 32-55.
Finding. No feasible mitigation measures are 'identifiedto
reduce this impact. Therefore, a Statement of Overriding
Considerations must be adopted upon approval of the Project.
IMPACT 3.5/U. Increase in Energy Usage Through Operation of the
Water Distribution System. Development of the Project will
result in increased water demand and will require increased
energy use to operate a water distribution system, especially for
pumping water to the system and to storage. DEIR page 3.5-21.
Mitiqa~ion Measure 3.5/40. Plan, design, and construct the
water distribution system for energy efficient operation.
Design~'pump stations to take advantage of off-peak energy.
DEIR page 3.5-21.
Finding. Changes or alterations have been required in, or
incorporated into the Project. However, even wi~h these
.changeS, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the project.
Rationale for Finding. Use of energy efficient water
distribution systems and operations will reduce the amount
of energy used, but these actions cannot fully mitigate the
impact.

iMPACT B.5/V. Potential Water Storage Reservoir Failure. Loss
of storage in proposed water distribution reservoirs from
landslides, earthquakes, and/or undermining of the reservoir
through inadequate drainage would adversely affect the.ability of
the water supply system to maintain water pressures and to meet
fire flows. DEIR page 35-21.
Mitiqation Measure 3.5/41.0. Require water reservoir
construction to meet all applicable DSRSD standards.
Prepare soils and geotechnical investigations to determine
potential landslide and earthquake impacts. Design the
reservoirs to meet current seismic codes, and to provide
adequate site drainage. DEIR page 3.5-21.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the .significant effect identified in the Final EIR.
Rationale for Findinq. Soils and geotechnical studies will
insure that reservoirs will be designed and constructed to
comply.with current seismic, DSRSD, and site drainage
standards, thereby avoiding the risk of structural damage or
failure.
IMPACT $.5/W. Potential Loss of System Pressure. Loss of
pressure in' the proposed water distribution systems could result
in contamination of the distribution system and would not allow
adequate flows and pressures essential for fire flow. DEIR page
3.5-22. ~
Mitiqation Measure 3.5/42.0. The proposed water pump
stations shall meet all applicable standards of DSRSD and
shall include emergency power generation back-up. DEIR page
3.5-22.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. Compliance with DSRSD standards will
minimize the risk of pressure being lost. Providing
~mergency power generators will insure the pumps, will
continue operating, thereby avoiding the risk of contamina-
tion in the distribution system and insuring that adequate
water flows are available for fire protection.
IMPACT 3.5/x. Potential Pump Station Noise. Proposed water
system pump lstations would generate noise during their operation
that could adversely affect the surrounding community. DEIR page

Mitiqation Measure 3.5/43.0. Design pump stations to reduce
sound levels from operating pump motors and emergency
generators. DEIR page 3.5-22.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Reducing sound levels of the
mechanical equipment will reduce the amount of noise
perceivable by surrounding residents, thereby avoiding the
impact.
IMPACT 3.5/y. Potential FlOoding. Development of the Project
and development of former agricultural, rural, and open space
lands throughout the Tri-Valley will result in an increase in
runoff to creeks and will result in an increased potential for
flooding. This is also a potentially significant cumulative
impact. DEIR page 3.5-25, 5.0-9.
Mitiqation Measure 3.5/44.0 to 48.0. Pursuant to Specific
Plan POlicies 9-7* and 9-8,* Action Programs 9R* and 9S,*
and other EIR mitigations, require a master drainage plan
for each development project in the RPA to provide drainage
facilities adequate to prevent increased erosion or flood-
ing, including channel improvements wi~h natural creek~
bottoms, and side slopes with natural vegetation.. This
design level plan shall include studies of the development
project area hydrology, potential impacts of the development
project, and proposed design features to minimize runoff
flows and their effects on erosion and riparian vegetation.
'Development projects shall also address potential downstream
floodimg, and shall include retention/detention facilities
and/or~ienergy dissipators to minimize and control runoff,
discharge, and to minimize adverse biological and visual
effects. Construct storm drainage facilities in accordance
with approved storm drainage master plan. (*Specific Plan
provisions adopted throughout RPA.) DEIR 3.5-25 to -26,
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. Through planning and implementation
of storm drainage master plans, development projects will
minimize the amount of runoff to creeks and will provide
drainage facilities to control the rate and location of
runoff that does discharge into creeks. These measures will
minimize the increase in runoff, thereby avoiding increased
flooding potential.

IMPACT 3.5/~.. Reduced Groundwater Recharge. Increasing the
amount of impervious surfaces in the Project area could reduce
the area's already minimal groundwater recharge capabilities.
This is also a potentially significant cumulative impact, as
impervious surfaces increase throughout the Tri-Valley. DEIR
page 3.5-26~ 5.0-9 to -10.
Mitigation Measure .3.5/49.0 to 50.0. Pursuant to Specific
Plan pOlicy 9-9* and other EIR mitigations, plan facilities
and operations that protect and enhance water quality;
support Zone 7 's ongoing groundwater recharge program for
the nearby Central Basin, which contains the majority of the
Tri-Valley' s groundwater resources. ( *Specific Plan
provisions adopted throughout RPA. ) DEIR page 2.5-26,
5.0-9.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. These mitigation measures protect
and enhance what minimal groundwater recharge capability
exists'?in the Project area.
IMPACT 3.5/AA. No~-Point So%trces of Pollution. Development of
the Project could result in a deterioration of the q~.~ality of
stormwater due to an increase in non-point sources of pollution
including (1)-urban runoff; (2) non-stormwater discharges to
storm drains; (3) subsurface drainage; and (4) construction site
runoff (erosion and sedimentation). This is also a'potentially
significant'cumulative impact as other projects in the subregion
are developed. DEIR page 3.5-26.
Mitiqation Measure 3.5/52.0 to 55.0. The city shall develop
a community based education program on non-point sources of
pollution, coordinating such programs with current Alameda
County programs. The City shall require all development to
meet the requirements of the City's "Best Management
Practices", the City's NPDES permit, and the County's Urban
Runoff Clean Water Program to mitigate stormwater pollution.
DEIR 3 5-27, 5.0-10, Addendum.
Findina. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Education programs will acquaint all
Project area residents with the issue of non-point
pollution, and will suggest ways residents can avoid such
pollution. Existing City, County, and State regulatory
programs will insure that potential impacts of non-point
114 \eastdub\ find (4) 37
sources of pollution or stormwater quality will be mitigated
to a level of insignificance.

IMPACT 3.6/B. Earthquake Groined Bhaking: Primar~ Effects.
Earthquake ground shaking resulting from large earthquakes on
active fault zones in the region, could be strong to violent, and
could result in damage to structures and infrastructure and, in
extreme cases, loss of life. DEIR page 3.6-7.
Mitiqation Measure 3.6/1..Q. Use modern seismic design for
resistance to lateral force in construction of development
projects, and build in accordance with Uniform Building Code
and applicable county and city code requirements. DEIR page
3.6-7.
Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for F.indinq. Modern seismic design and compliance
with applicable building codes will reduce the risk of
structural failure, major structural d~mage, an~loss of
life from the effects of ground-shaking. These-actions will
not, however, completely avoid the impact.
IMPACT 3.$/C. ~arth~uake Ground Sha~ing: Secondar~-:Effects. The
secondary effects of ground shaking include seismically-induced
landsliding~ differential compaction and/or settlement. This is
also a significant cumulative impact in that further development
in the area~Could expose residents to significant safety hazards
and could strain emergency response systems. DEIR page 3.6-8,
5.0-10.
Mitiqation Measure 3.6/2.0. In relatively flat areas,
development should be set back from unstable and potentially
unstable land or these landforms should be removed,
stabilized, or reconstructed. Where improvements are
located on unstable land forms, use modern design,
appropriate foundation design, and comply with applicable
codes and_policies. DEIR page 3.6-8, 5.0-10.
Mitiqation Measure 3.6/3.0. In hillside areas, where
development may require substantial grading, require
appropriate grading and design to completely remove unstable
and potentially unstable materials. DEIR page 3.6-8,
5.0-10~
114 \eastdub\ find (4) 3 8
Mitigation Measures 3.6/4.0 to 5.0. Use engineering
techniques and improvements, such as retention structures,
surface and subsurface drainage improvements, properly
designed keyways, and adequate compaction to improve the
stability of fill areas and reduce seismically induced fill
settlement. DEIR page 3.6-8, 5.0-10.
Mitigation Measure 3.6/6.0. Design roads, structural
foundations, and underground utilities to accommodate
estimated settlement without failure, especially across
transitions between fills and cuts. Remove or reconstruct
potentially unstable stock pond embankments in development
areas. DEIR page 3.6-8, 5.0-10.
Mitigation Measure 3.6~7.0. Require all development
projects in the Project area to perform design level
geotechnical investigations prior to issuing any permits.
The investigations should include stability analysis of
natural and planned engineered slopes, and a displacement
analysis to confirm the effectiveness of mitigation measures
proposed in the investigation. DEIR page 3.6-9, 5.0-10.
Mitigation Measure 3.6/8.0. Earthquake preparedness plans
should be developed by the City and all Project site
residents and employees should be informed of appropriate
measures to take in the event of an earthquake./ DEIR page
3.6-9, 5.0-10.
Finding. Changes or alterations have been required in, or
'incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Mitigations 3.6/2.0 to 6.0 provide
specific engineering techniques for reducing the effects of
ground shaking throughout development in the Project area.
Mitigation 3.6/7.0 requires development projects to apply
these and other available engineering techniques at a design
level, to identify specifically the effects that can occur
on a' p.articular site, to propose mitigations specific to
those effects and the site, and to provide a means for
evaluating the likely success of those measures. Through
these engineering, planning, and design mitigations,
development projects will be able to anticipate and avoid or
reduce :ground shaking effects before the development is
built.
IMPACT 3.6/D. Substantial Alteration to Projeot Site Landforms.
Development of the Project area could result in permanent change
to the Project site's existing topography, particularly in
hillside areas. This is also a significant cumulative impact as
the hillsides and ridge!ands of surrounding Tri-Valley cities are

DEIR page 3.6-9,
Mitigation Measures 3.6/9.0 to 10.0. Adapt improvements to
natural landforms in order to minimize required cuts and
fills through such techniques as construction of partial
pads and use of retaining structures and steeper cut and
fill slopes where appropriate and properly designed.
Further reduce landform alteration by carefully siting
individual improvements on specific lots after identifying
geotechnically feasible building areas and alignments. Site
improvements to avoid adverse geotechnical conditions and
the need for remedial grading and use techniques such as
clustering where appropriate to minimize grading and/or
avoid adverse geotechnical conditions. DEIR page 3.6-9.
5.0-10.
Finding. Changes or alterations have been required in, or
incorpOrated into, the Project that avoid or substantially
lessen?the significant effect identified in the Final EIR.
Rational.e for Finding. These mitigation measures provide
design~and engineering techniques which maintain natural
landfo!lns to the greatest degree possible, and thereby
minimize alteration of those landforms. The mitigations
also require that geotechnical conditions be identified for
development projects, allowing individual projects to
identify and reduce, or in some cases completely avoid, the
condition which might otherwise require alteration.
IMPACT 3.6/F, G. groundwater Impacts. Groundwater Impacts
&ssooiate~ with Irrigation. Shallow groundwater conditions occur
in places throughout the RPA and could be caused by irrigation
associated with development of the RPA. These conditions can
adversely affect the performance of foundation and pavements,
particularly in areas with expansive soils and bedrock. In
addition, shallow groundwater can cause slope instability,
including landsliding and fill settlement, and can lead to
liquefactioh of RPA soils. DEIR page 3.6-10.
Mitigation Measures 3.6/11.0 to 13.0. Prepare detailed.
design?level geotechnical investigations on development
projects within the RPA, to locate and characterize
groundwater conditions and formulate design criteria and
measures to mitigate adverse conditions. Control
groundwater by construction of subdrain systems, remove

Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. The geotechnical investigation will
identify areas which have groundwater, and development will
proceed in accordance with measures to protect structures
and improvements from slope and soil instability due to
shallow groundwater.
IMPACT 3.6/H. Shxinking and Swelling of Expansive Soils and
Bedrock. The Project site contains expansive soils and bedrock,
which tend to shrink upon drying and swell upon wetting. This
process can~cause distress to overlying structures and infra-
stru=ture, Causing damage to foundations, slabs, and pavements.
DEIR page 3.6-11.
Mitigation Measures. 3.6/14.0 to 16.0. Prepare design level
geotechnical investigations for development projects in the
Project area to characterize site-specific soils and bedrock
conditions, and to formulate appropriate design criteria and
mitigation measures for those conditions. Such responsive
measures include, but are not limited to, controlling
moisture in the soils and bedrock, and designing foundations
and pavements to be built either below the zone of seasonal
moisture change, or upon structurally supportive floors and
after removal of the expansive materials. DEIR page 3.6-11

Rationale for Finding. The design level geotechnical
evaluation will identify expansive soils and bedrock and
insure that special techniques are used in these areas to
reduce the risk of structure and infrastructure damage.
IMPACT 3.6/I. Natural ~lope Stability. The Project area
contains active and dormant landslides, as well as steep slopes
and colluvium-filled swales, which are subject to potential slope
instability~ and could cause damage to structures and infra-
structure located in these areas. DEIR page 3.6-12.
Mitiqation Measures 3.6/17.0 to 19.0. Development projects
within'~the Project area should prepare design level
geotechnical investigations to characterize site-specific
slope stability conditions and to formulate appropriate
design.~criteria and mitigation measures in response to those
conditions. Such design measures and mitigations include
siting~development away from unstable landforms and from
114 \eastdub\ find ( 4 )
41
slopes?greater than about 30%, and providing lower density
development in steep, unstable areas. Where unstable areas
cannon,be avoided, design measures and mitigations include
removing the unstable material, reconstructing or repairing
the unstable area, or engineering structural responses,
including subsurface drainage improvements. (See also MM
3.6/26.0, recommending maintenance and inspection plans for
drainage systems. DEIR page 3.6-14.) DEIR page 3.6-12 to

Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. The design level geotechnical
investigation will disclose areas which may be susceptible
to slope instability. Special techniques, such as siting of.
structure and improvements, removing the unstable materials,
and providing structural remediation, will improve slope
stability.
IMPACT 3.6/J. ~ut an~ fill slope stability. Potentially
unstable cut and fill slopes may fail or settle, causing damage
to structures and infrastructure. DEIR Page 3.6-13.
Mitigation Measures 3.6/20.0 to 21.0. Require~grading plans
for hillside areas, which plans minimize grading and
required cuts and fills by adapting roads to natural
landforms, stepping structures down steeper slopes, and
demonstrating compliance with applicable buildi'ng code and
other applicable City and County requirements. DEIR page
3.6-13.
Mitiqation Measures 3.6.f22.0 to 25.0. Detailed design level
geotechnical investigations such as that required by
mitigation measure 3.6/17.0 should describe and evaluate cut
and fill slopes proposed for development projects in the
RPA. Retaining structures, reinforcement and drainage
measures should be provided on cut slopes as d~termined by
code requirements and the specific conditions identified in
the ge0technical investigation. Unretained cut slopes
should.generally not exceed 3:1. Filled slopes steeper than
5:1 should be keyed and benched into competent material and
provided with subdrainage prior to placing engineered fill.
DEIR pages 3.16-13 to -14.
Mitigation Measure 3.6/26.0. Development projects in the
Project area should prepare plans for the periodic in-
spection and maintenance of subsurface drainage features,
and the removal and disposal of materials deposited in
surface drains and catch basins. (See also measures
114 \eastdub \find (4)
42
described in MM 3.6/28.0.) The plans should include
inspection and disposal procedures, schedule and reporting
requirements, and a responsible party, and should emphasize
overall long-term Project monitoring-and maintenance. DEIR
page 3..6-14.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen'the significant effect identified in the Final EIR.
Rationale for Finding. The detailed design level geotechni-
cml investigation will identify areas where cut and fill
slopes are proposed. Specific grading plans affecting these
conditions would be required to show how each development.
project will minimize cut and fill slopes, and how the
remaining slopes will be stabilized through siting or engi-
neering features. Long-term monitoring and maintenance
plans will ensure that the design facilities and engineered
features effectively protect the cut and fill slopes over
the long term.
LMP~CT 3.6/K, L. Erosion and Se4imentation: Construction-Relate~

significantcumulative impact as similar sites are developed
throughout the Tri-Valley. DEIR page. 3.6-14, 5.0-i1.
Mitigation Measure 3.6/27..9. Time grading activities to
avoid the rainy season as much as possible, and implement
interim control measures, including but not limited to,
providing water bars, mulch and net blankets on exposed
slopes, straw bale dikes, temporary culverts and swales,

seotion S.7 -- Biological Resources
IMPACT 3.?/~. Direct Habitat Loss. Under Alternative 2, the
Project will result in the loss, degradation, or disturbance of
1900 acres of existing vegetation. No unique or rare plant
species occur in the Project area; however, urbanization will
substantially reduce the habitat and range for botanical and
wildlife species which are resident or migratoryusers of the
RPA. The Project contributes to the cumulative., ongoing 'loss of
natural habitat in the Tri-Valley region, and is also a
potentially significant cumulative impact. DEIR page 3.7-9, 5.0-

Mitigation Measures 3.7/1.0 to 3.0. Pursuant to Specific
Plan Policies 6-21, and 6-23,* and Action Program 60,*
directfdisturbance of trees or vegetation should be
minimized and restricted to those areas actually designated
for construction of improvements. Development/projects
should, include vegetation enhancement/management plans for
all open space areas identifying ways to enhance the
biological potential of the area as wildlife habitat and
focusing on such measures as reintrod~c'ing native species to
increase vegetative cover and plant diversity. Development
projects shall also be required to prepare a detailed
revegetation/restoration plan, developed by a qualified
revegetation specialist, for all disturbed areas that are to
remain undeveloped. (*Specific Plan provisions adopted

Mitigation Measure 3.7~4.0. The city shall develop and
implement grazing management plans to protect riparian and
wetland areas, increase plant diversity, and encourage the
recovery of native plants, especially perennial grasses.
DEIR page 3.7-9, 5.0-11.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen.:the significant effect identified in the Final EIR.
Rationale for Finding. Restricting direct disturbance to
actual construction areas will reduce the amount of habitat
lost. The vegetation and grazing plans will protect and
restore disturbed areas to minimize t~e amount of habitat
loss and to enhance the value of the habitat area remaining.

Mitiqation Measures 3.6~18.0, 22.0, 23.0, and 3.11~1.0.
Development should avoid siting on steep slopes and should
observe special design and engineering mitigation features
where construction occurs on 3:1 or steeper slopes. The
City of Dublin shall require dust deposition mitigations
during construction, including but not limited to, watering
the construction site, daily clean-up of mud anddust,
replanting and repaying and other measures to reduce wind
erosion. DEIR pages 3.6-12 to -13, 3.7-10, 3.11-3 to -4.
Findihq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen~ithe significant effect identified in the Final EIR.
Rationale .for Finding. Requiring construction to avoid
sitingon steep slopes will protect hillside vegetation and
reduce, erosion impacts. Where disturbance is necessary,
engineering and other techniques to reduce erosion and
-sedimentation and promote slope stability will also ensure
that revegetation efforts to control erosion will be more
efficient and successful.
IMPACT 3.7/C. Loss or Deq~a~ntion of Bota~ic&lL~ sensitive
'Habitat. Direct loss and degradation from grading, road
construction, and culvert crossings could adversely affect the
Project area's unique and sensitive Northern Riparian Forest,
Arroyo Willow Riparian Woodland, and Freshwater Marsh habitats.
Indirect impacts could result from increased sedimentation or
spoil deposition affecting stream flow patterns and damaging
young seedlings and theroots of woody plants. This impact is
also a potentially significant cumulative impact. DEIR page 3.7-

Wetland Area.s. Pursua/~t to Specific Plan Policies 6-9,*
6-10,* and Action Program 6E,* natural riparian and wetland
areas shall be preserved wherever possible. All development
projects in the RPA shall consult with the Army Corps of
Engineers (COE) and the California Department of Fish and
Game (DFG) to determine these agencies' jurisdiction over
the riparian or wetland area. These areas shall be
incorporated into project open space areas. Any lost
riparian habitat shall be replaced as required by DFG. Any
lost wetlands shall be mitigated per COE's "no net loss"
policy.. (*Specific Plan provisions adopted throughout RPA.)
DEIR p~ge 3.7-10, and -11, 5.0-12.
Mitiqation Measures 3.7/8.0 to 10.0, 12.0 to 14.0. PursUant
to specific Plan Policies 6-11 to 6-13,* and Action Programs
6F to 6H,* the City shall require revegetation of natural
stream corridors with native plant species and' preservation
and maintenance of natural stream corridors in the Project
area, through measures including, but not limited to,
avoiding underground drainage systems in favor of natural
open-stream channels and retention basins. The city shall
establish a stream corridor system (see Specific Plan Figure
6.1) to provide multi-purpose open space corridors for
pedestrian and wildlife circulation. The City should also
work with Zone 7 and DFG to develop a stresm corridor
restoration program, with standards for grading,, stabiliza-
tion, ~nd revegetation, and long-term management' of RPA
stream~channels. Development projects in the RPA are to be
reviewed against, and any approval shall be cons:istent with,
the program standards. (*Specific Plan provisions adopted
throughout RPA.) DEIR page 3.7-10 to -12, 5.0-12; RC ~14-

Mitiqation Measure 3.7/15.0. Pursuant to Specific Plan
Action Program 6K,* the City of Dublin shall establish and
maintain a liaison with state and federal resource manage-
ment agencies throughout the planning and development
process of individual development projects, in order to
avoid violations of state and federal regulations and insure
that specific issues and concerns are recognized and
addressed. (*Specific Plan provimions adopted throughout

substantially lessen the Pro~ect-related significant effects
identified in the final EIR. However, these changes will
not avoid the cumulative effects of lost or degraded
biologically sensitive habitat. Therefore, a Statement of
overriding Considerations must be adopted upon approval of
the Project.
RatioNale for FindiDg. Requiring compliance with "no net
loss" policies will ensure that the amount of habitat shall
remain.constant. By incorporating wildlife corridors into
Project plans, wildlife habitats will be enhanced and will
not become isolated because wildlife will be able to migrate
through these corridors as necessary. Disturbance of
natural stream corridors can reduce the habitat value of
these areas, but will be minimized by requirements to
preserve and maintain these corridors in a natural, open
condit$on, and by requiring construction to take place in
the dry season. Any disturbed streams shall be rebuilt,
reconstructed and revegetated according to the stream
corridor plan, which will further enhance and protect
habita~ values in the RPA. Even with these protections for
the RPA's biologically sensitive resource, the cumulative
impacti~¢annot be fully mitigated.
IMPACT 3.TfD. .San Joaquin Kit ~ox. Construction of new roads
and facilities could adversely impact kit'fox by deSt=oying
potential dens or burying foxes occupying dens at the .time of
construction. Modification of natural habitat could reduce
available prey and den sites. Increased vehicle traffic, the
presence of humans and domestic dogs, and resident Use.' of poison
for rodent control could kill or disturb foxes or reduce their
prey populations. DEIR page 3.7-12 to -13.
Mitiaation Measure 3.7/18.0. The City shall require all
development in the RPA to comply with the East Dublin San
Joaqui~ Kit Fox Protection Plan outlined in Appendix E, DEIR
Part II. Extensive mitigation measures stress siting urban
development to avoid kit fox habitat where possible, and
protec~:ing and enhancing the habitat which remains primarily
in the!!Open Space and Rural Residential areas. Mitigations
includ~ measures for pre-construction and construction
conditions, and address steps to be taken if potential or
known dens are identified. DEIR page 3.7-13, DEIRAppendix
~ (as revised following RC ~20-7.)
Mitiqation Measure 3._7/18..1. The City of Dublin shall work

Mitigation Measure 3.7/19.0. Pursuant to Specific Plan
Action!Program 6N,* the City shall restrict rodenticide and
herbicide use. (*Specific Plan provisions adopted
throughout RPA.) DEIRpage 3.7-13.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for. Finding. Appendix E provides a comprehensive
protection plan addressing several phases of kit fox
protection, from avoidance of potential dens to maintenance
of habitat. Through this plan, the Project will avoid most
direct?and indirect adverse effects on any kit fox that
might be present in the Project area.
IHPACTS 3.7~ff to I. Re~-legged ffrog, California Tiger
Salamander, Western Pond Turtle, Tri-Colored Blackbird. The
destruction and alteration of water impoundments and stream
courses in the RPA threatens to eliminate habitat for these
species, increased sedimentation into the riparian areas could
reduce water quality and threaten breeding and larval habitat.
Disturbance of the already minimal vegetation in the stream
courses could reduce habitat opportunity for adult species.
Increased vehicle traffic and new road construction could
increase direct mortality. Harassment and predation-..by feral
dogs and cats already occurs, and would increase with increased
residential development. DEIR page 3.7-13 =o -14.
Mitigation Measures 3.7/20.0 to 22.0. Pursuant to Specific
Plan Action Program 6L* and other EIR mitigations, develop-
ment p~ojects in the RPA shall prepare open space plans to
enhance and preserve existing habitat and revegetation plans
for any disturbed open space or habitat areas and shall
preserve and protect riparian, wetland, and stream corridor
areas Whenever possible. (See Ms 3.7/2.0 to 3.0.)
Maintain a minimum buffer of at least 100 feet around
breeding sites of the red-legged frog, California tiger
salamander, and Western pond turtle. Development projects
in theRPA shall conduct a pre-construction survey within
sixty days prior to habitat modification to verify the
presence of sensitive species. (*Specific Plan provisions
adopted throughoutRPA.) DEIR page 3.7-14.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or ~ub~tantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Open space protection, revegetation,
and restoration planning, as well as planning to protect and
enhance wetland and riparian areas will also protect and
11~ \ea~tdub\find ( 4 )

minimize impacts to the riparian habitat necessary for the
specie~ identified in this impact.
ZMPA~T8 $.7/K. Golden Eagle.: The conversion of grasslands and
the consequent reduction of potential prey could reduce the
amount and quality of foraging habitat for golden eagles. Noise
and human activity associated with development could also disrupt
foraging activities. Elimination of golden eagle foraging habi-
tat is also a potentially significant cumulative impact which
contributes to the overall regional loss of foraging habitat for
this species. DEIR page 3.7-15, 5.0-12.
Mitigation Measure ~z7/25.0. Designate substantial areas of
land in the Project area as Open Space or R~ral Residential
(including future study areas), providing open space
protection and low intensity development that will also
provide a suitable foraging habitat. DEIR page 3.7-15,
5.0-12.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen'the significant effect identified in the Final EIR.
RationAle for Finding. Providing a natural open space zone
aroundithe existing golden eagle nest avoids destruction of
the nesting site; providing an additional buffer, during the
golden:eagle reproductive period further protects the
integrity of the existing nesting site. The natural open
space zone, together with the over acres of open.
space and low intensity development across the.Project site
provides ample opportunity to maintain effective foraging
habitat for golden eagles.
IHP~CT ~.7/L. ~olden Eagle and O~her Raptor Electrocutions.
Golden eagles and other raptors which perch or fly into high-
voltage transmission lines may be electrocuted. DEIR page
3.7-15.
Mitigation Measures 3.7/26.0 and 3.4!42.0. Require all
utilities to be located below grade where feasible.
Pursuant to Specific Plan Action Program 6M,* require all
transmission lines to be undergrounded where feasible.
Where not feasible, design specifications to protect raptors
from electrocution shall be implemented. These specifica-
tions include, but are not limited to, spacing dangerous
components; insulating conductors,, using non-conductive
materials, or providing perch guards on cross arms; and
avoiding grounded steel cross arm braces. (*Specific Plan
provisions adopted throughout RPA.) DEIR page 3.4-24, 3.7-

Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Undergrounding utilities, including
all transmission lines, avoids the electrocution hazard.
Where the hazard cannot be avoided through underg-rounding,
the design specifications identified in the mitigations
reduce.~the electrocution hazards by neutralizing and/or
covering the features that provide opportunities for
electrocution.
IMPACT 3.7/M, N. Burrowing Owl and America~ Ba~ger. Annual
grasslands in the. RPA provide suitable habitat for burrowing
owls. Development and related construction activity could
destroy both burrowing owl and American badger burrows. Harass-
ment by feral dogs and cats, as well as use of poisons for rodent
control, could harm these species and/or reduce their prey
populations. D~IR page 3.7-16 to -17.
Mitiga~ion...Measures 3.7/20.0 and 27.0. Pursuant to Specific
Plan Action Program 6L* and other EIR mitigations, develop-
ment projects in the RPA shall conduct a pre-construction
survey within sixty days prior to habitat modification to
verify the presence of sensitive species. The projects
shall maintain a minimum buffer of at least 30~-.feet around
the breeding sites of the American badger durimg the
breeding season (March to September) to avoid direct loss of
individuals. Also, projects shall maintain a minimum buffer
of at least 300 feet around known or identifie~'nesting
sites of the burrowing owl, or implement other mitigation
actions pursuant to standardized protocol now under
development, including relocation of nesting sites in
coordination with the USFWS and the CDFG. (*Specific Plan
provisions adopted throughout RPA.) DEIR pages 3.7-14, and
-17; RC ~15-60.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. The pre-construction survey and
required buffer zone around known nesting and breeding sites
preserves these species' burrows by allowing them to be
avoided during the construction and development process.

Finding. Changes or alterations have been req~,ired in, or
incorporated into, the Project that avoid or. substantially
lessen the significant effect identified in the~ Final EIR.
Rationale for Finding. The mitigations provide..
preservation, enhancement and maintenance features for
riparian and freshwater marsh habitats upon which these
species rely for forage. Protecting and enhancing this
habitat avoids the impact of lost habitat.
IMPACT 3.7~S. Special Status Invertebrates. Impacts to special
status invertebrates cannot be estimated at this time. DEIR page

page 3.8-5.
Findinq. Changes or alterations have been required in, or
· incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale-for FiD~inq. By protecting key natural and visual
elements, the Project maintains the natural features of the
RPA, which make it unique. The general design guidelines
for the Project, including a village center, town center,
mixed Use orientation, and varying lot sizes, Provide a
varied'development pattern, which avoids the look of
standard cookie-cutter tract developments.
IHP~CT 3.8/B. ~ltera~ion of Rural/Open Space Visual Character.
Urban development of the RPA will substantially alter the
existing rural and open space qualities that characterize eastern
Dublin. This is also a significant cumulative impact as the
natural rural character of the Tri-Valley subregion is replaced
by urban development. DEIR page 3.8-5, 5.10-12.
Mitiqation Measure 3.8/2.0. Implement the land use plan for
the RPA, which plan emphasizes retaining the predominant
natural features, such as ridgelines and watercourses, and
pre~erve~ the ~en~e of openness that characterizes Eastern
Dublin.~ DEIR page 3.8-5, 5.0-12.
Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding
Considerations must be adopted upon approval of the Project.
114 \eastdub\find (4) 52
Rationale for Finding. Maintaining predominant natural
features minimizes the alteration of the RPA's current rural
open space character; however, it does not fully mitigate
this impact.
XHP&CT 3.a/C. Obscuring Distiuctive Natural Features. The
characteristic unvegetated landscape of the RPA heightens the
visual importance of existing trees, watercourses, and other
salient natural and cultural features. The Project has the
potential to obscure or alter these existing features and thereby
reduce the visual uniqueness of the site. DEIR page 3.8-5.
Mitigation Measure 3.8/3.0. Pursuant to Specific Plan
Policy 6-28,* preserve the natural open beauty of the hills
and other important visual resources, such as creeks and
major stands of vegetation. (*Specific Plan provisions
adopted throughout RPA. ) DEIR page 3.8-5.
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen'i~the significant effect identified in the Final EIR.
Rationale for Finding. This mitigation measure calls for
preservation of the RPA's important visual resources,
thereby avoiding the impact of obscured or altered visually
important features.
IMPACT 3.8/D. ~lteration of Visual Quality of Hillsides.
Grading and excavation of building sites in hillside areas will
severely compromise the visual quality of the RPA. "DEIR page
3.8-6.
Mitiqation Measures 3.8/4.0 to 4.5. Pursuant to Specific
Plan Policies 6-32,* and 6-34 to -38,* grading and
excavation throughout the RPA should be minimized, by using
such g~ading features as gradual transitions from graded
ares to natural slopes, by revegetation of graded areas, by
maintaining natural contours as much as possible and grading
only the actual development areas. Building pads in
hillside areas should be graded individually or stepped,
wherever possible. Structures and roadways should be
designed in response to the topographical and geotechnical
conditions. Structures should be designed to blend in with
surrounding slopes and topography and the height and grade
of cut and fill slopes should be minimized wherever
feasible. (*Specific Plan provisions adopted throughout
RPA.) DEIR page 3.8-6.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
lla \eas'~lub \find (a)
53
Rationale for FindinG. The various grading techniques
identifie~, together with revegetation and.s~n~i~ive
building design will avoid the impact by minimizing physical
alteration throughout the RPA.
IMPACT 3.S/E. Alteration of Visual Quality of Ridges.
Structures built in proximity to ridges may obscure or fragment
the profile'of visually-sensitive ridgelines. DEIR page 3.8-6.
Mitiaa~ion. Measures 3.8f5.0 to 5.2. Pursuant to Specific
Plan Policy 6-29,* development is not permitted on the main
ridgeline that borders the Specific Plan area to the north'
and east, but may be permitted on the foreground hills and
ridgelands. Minor interruptions of views of the main
ridgeline by individual building masses may be permitted
only where all other remedies have been exhausted. Pursuant
to Specific Plan Policy 6-30* and General Plan Amendment
Guiding Policy E, structures shall not obstruct scenic views
and shall not appear to extend above an identified scenic
ridgetop when viewed from scenic routes. (*Specific Plan
provisions adopted throughout RPA.) DEIR page 3.8-7.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessens.the significant effect identified in the Final EIR.
Rationale for Finding. Prohibiting development along the
main ridgeline in the RPA preserves the visual".quality of
this resource. Limiting development so that structures are
not silhouetted against other scenic ridgetops,· as well as
requiring that a backdrop of natural ridgeline remain
visible, minimizes the obstruction or fragmentation of
visually sensitive ridgelines.
IMPACT 3.8/F. Alteration of Visual character of Flatlands.
Commercial and residential development of the RPA's flatlands
will completely alter the existing visual character resulting
from valley grasses and agricultural fields. DEIR page 3.8-7.
Mitiqa~ion Measures. None identified. DEIR page 3.8-7.
Findinq. No Gha~ges or alterations are available to
substantially lessen this impact. Therefore, a Statement of
Overriding Considerations must be adopted upon approval of
the Project.
Rationale for Finding. Development of the Project site's
flatter areas is regarded as a "trade-off" measure designed
to preserve slopes, hillsides, and ridgelines.

Mitiqation Measure 3~8/6.0. Pursuant to Specific Plan
Policy 6-39,* protect the visual character of Tassajara
creek and other stream corridors from unnecessary alteration
or disturbance. Adjoining development should be sited to
maintain visual access tot he stream corridors. Implement
earlier identified mitigation measures 3.7/8.0, 12.0, and
13.0, to revegetate stream corridors to enhance their
natural appearance, to prepare a comprehensive stream
corridor restoration program, and to establish dedication of
land along both sides of stream corridors. (*Specific Plan
provisions adopted throughout RPA.) DEIR page 3.8-7 to -8,
3.7-10 to -11.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. Preserving the RPA watercourses will
retain both their visibility and function as distinct
landscape elements. Special attention to stream corridors
through revegetation, restoration, and dedication., of land
along both sides, will further enhance this distinct
landscape element.
IMPACT 3.8/I. Scenic Vistas. Development on the RPA will alter
the character of existing scenic vistas and may obscure important
sightlines. DEIRpage 3.8-8.
Mitiqation Measure 3.8~.?.0 to 7.1. Pursuant to Specific
Plan policy 6-5* and other EIR mitigations, preserve views
of designated open space areas. The City will conduct a
visual survey of the RPA to identify and map viewsheds of
scenic vistas. (*Specific Plan provisions adopted
throughout RPA.)
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. Identifying and mapping critical
viewsheds allows the City to consider specific ways of
preserving those views when reviewing development projects
within'~the RPA.
IMAGE 3.8/J~ Scenic Routes. Urban development of the RPA will
significantly alter the visual experience of travelers on scenic
! 14 \eastc~]~ \~ucl (4) 55
routes in e~stern Dublin. As quiet rural roads become major
suburban thoroughfares, foreground and distant views may be
obstructed. DEIR page 3.8-8 to -9.
Mitigation Measure. 3.$/8.0. Pursuant to Specific Plan
Action Program 6Q,* the City should officially adopt
Tassajara Road, 1-580, and Fallon Road as designated scenic
corridors, should adopt scenic corridor policies, and should
establish development review procedures and standards to
preserve scenic vistas. (*Specific Plan provisions adopted
throughout RPA.) DEIR page 3.8-9.
Mitigation Measure 3.8/8.1. Pursuant to Specific Plan
Action Program 6R,* the City should require that projects
with potential impacts on scenic corridors submit detailed
visual analysis with development project applications. The
analysis shall include graphic simulations and/or sections
drawn from affected travel corridors and representing
typical views from scenic routes. (*Specific Plan
provisions adopted throughout RPA.) DEIR page 3.8-9.
Fi~dinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen'the significant effect identified in the Final EIR.
Rationale for FindiDq. Establishing scenic corridor
policies will insure that the visual experience~of travelers
along scenic routes be maintained as much as possible.
Requiring visual analyses will allow the Cit~ to specifi-
cally review development projects for their visual impacts
and to review how locations of structures and associated
landscaping can be used to adjust the project design to
minimize its visual impacts from scenic routes.

manner. DEIR page 3.9-6.
Mitlqatlon Mea~ure~ 3.9/1.0 to 4.0. Develop a te~ting
program to determine the presence or absence of hidden
deposits in all locations of prehistoric resources. Ail
locations containing these components shall be recorded with
the State of California and their borders will be staked so
that professional survey teams may develop accurate location
maps. If any of these recorded and mapped locations are
affected by future construction or increased access to the
areas, evaluative testing, consisting of collecting and
114\eastdub\f£nd (4)

analyzing any surface concentration of materials, shall be
undertaken in order to prepare responsive mitigation
measures. The City shall hire a qualified archaeologist to
develop a protection program for prehistoric sites con-
taining significant surface or subsurface deposits of
cultural materials in areas where development will alter the
current condition of the resource. DEIR page 3.9-6 to -7.
Findina. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. Through these mitigations,
prehistoric resources can be identified and mapped, and
specific mitigation plans prepared as part of review of
development projects that will affect the resources.
IHP~CT 3.9/B. Disruption or Destruction of Unidentified Pre-
Historic Resources. Previously unidentified pre-historic
resources may exist in the RPA and would be subject to potential
disruption or destruction by construction and development
activities associated with the Project. DEIR page 3.9-7.
Mitigation Measures 3.9/5.0 to 6.0. Pursuant to Specific
Plan Policy 6-25* and Action Program 6P,* cease any grading
or construction activity if historic or prehistoric remains
are discovered until the significance and ~xtent of those
remains can be ascertained by a certified archaeologist.
Development projects in the RPA shall prepare an archaeolo-
gical site sensitivity determination and detai~ed research
and field reconnaissance by a certified archaeologist, and
develop a mitigation plan. (*Specific Plan provisions
adopted throughout RPA.) DEIR page 3.9-7.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. These mitigations will insure that
any significant prehistoric resources which are discovered
during~;development activities are not disrupted or
destroyed.
IMPACT 3.9/C. Disruption or Destruction of I~e~tified Historic
Resources. 'fDue to the level of development proposed in the RPA,
it is assumed that all historic sites identified in the 1988
inventory will be disturbed or altered in some manner. Even
cultural resources in the proposed Open Space and Rural Residen-
tial areas will potentially be disturbed or altered due to the
presence of new residential population.in the area. DEIR page
3.9-8.
114 \eastdub\[ind (4) 57
Mitigation Measures 3.9/7.0 to 12.0. Pursuant to Specific
Plan Policies 6-26* and 6-27* and other mitigations
identified in the EIR, all properties with historic
resources and all standing structural remains shall be
evaluated by an architectural historian as part of in-depth
archival research to determine the significance of the
resource prior to any alteration. All historic locations in
the 1988 inventory shall be recorded on official State of
California historical site inventory forms. These records
shouldf~be used to make sure that historical locations are
recorded-onto development maps by professional surveyors.

Section 3.10 -- Noise
X/~P~CT 3.10/~. Exposure of Proposed Rousing to Futttre Roadway
Noise. Proposed residential housing along Dublin.Boulevard,
Tassajara Road, Fallon Road, and Hacienda Drive will be exposed
to future noise levels in excess of 60 dB CNEL. DEIR page 3.10-
2.
Mitigation Measure 3.10/1.0. Require acoustical studies for
all residential development projects within the future CNEL
60 contour to show how interior noise levels will be reduced
to 45 dB.
i.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lesseni~the significant effect identified in the Final EIR.
Rationale for Findinq. The required acoustical studies must
show how interior noise exposures are reduced to 45 dB CNEL,
the minimum acceptable noise level.
IMPACT 3.10/B. Exposure of Existing Residences to .~uture Roadwa~
Noise. Increased traffic noise on local roads would, result in
significant cumulative noise level increases along Tassajara .(4
dB), Fallon (6dB), and Hacienda Roads of 6 dB. This is a
potentially significant cumulative impact in that small indivi-
dual Project noise increases considered together and over the
long term, will substantially increase overall noise levels.
DEIR page 3;~10-3, 5.0-13.
Mitiqa~ion Measures 3.10/2.0. Ail development projects in
the RPA shall provide noise barriers or berms near existing
residences to control noise in outdoor use spaces. DEIR
page 3210-3.
Mitiqati°n Measure 3.10/7.0. To mitigate cumulative noise
impacts, the City shall develop a noise mitigation fee to
pay for on- and off-site noise mitigations, including but
not limited to, noise barriers, earthen berms, or
retrofitting structures with sound-rated windows. DEIR page
5.0-13.
Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
ll4\eastdub\f~d (4)
59
RatioDale for Finding. Providing noise barriers or berms
will reduce noise exposure for existing residences; however,
mitigation may not be feasible at all locations because of
site constraints such as driveways and proximity to road-
ways. Furthermore, while developers will provide funding for
noise ~itigations to reduce overall noise levels, funds
derived from the experimental program may not adequately
mitigate the cumulative impact. Therefore, this noise
impact-cannot be fully mitigated.
IMPACT 3.10/D. Exposure of Proposed Residential Development to
Noise from Future Militar~ Training &ctivities at Parks Reserve
Forces Training Area (Camp Parks RFT&) and the Count~ Jail.
Residential development on the Project site within 6000 feet of
Camp Parks RFTA and the County Jail could be exposed to noise
impacts from gunshots and helicopter overflights. DEIR page
3.10-4.
Mitigation Measure 3.10/3..0. The city shall require an
acoustical study prior to future development in the Foothill
Residential, Tassajara Village Center, County Center, and
Hacienda Gateway subareas (as defined in Figure 4.2 of the
Specific Plan) to determine whether future noise impacts
from camp Parks and the county jail will be within accept-
able limits. This study should identify and evaluate all
potential noise generating operations. DEIR page3.10-4.
Finding. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for Finding. The required acoustical study will
identify noise sensitive areas in the Project site and noise
generating operations at Camp Parks and the jail and will
propose mitigation to reduce noise impacts to acceptable
limits. However, mitigation may not be possible at all
critical locations, so the impact may not be fully
mitigated.
iMPaCT 3.10/E. Exposure of Existing an~ Propose~ Resi~en=es to
Construction No~se. Construction would occur over years on the
Project site and will be accompanied by noise from truck activity
on local roads, heavy equipment used in grading and paving,
impact noises during structural framing, and pile driving.
Construction impacts will be most severe near existing residen-
tial uses along Tassajara Road and near existing uses in the
southern portion of the Project area. DEIR page 3.10-4.
114 \east4ub\find (4) 60
Mitigation Measures 3.....10/4.0 to 5.0. Development projects
in the RPA shall submit a Construction Noise Management
Program that identifies measures proposed to minimize
construction noise impacts on existing residents. The
Program shall include a schedule for grading and other major
noise-generating' activities, limiting these activities to
the shortest possible number of days. Other noise
mitigation measures include, but are not limited to,
restricting hours of construction activity, developing
construction vehicle access routes which minimize truck
traffic through residential areas, and developing a
mitigation plan for construction traffic that cannot be
avoided in residential areas. In addition, all development-
related operations should comply with local noise standards,
including limiting activity to daytime hours, muffling
stationary equipment, and locating that equipment as far
away from sensitive receptors as possible. DEIR page 3.10-
4 to -5.
Findinq. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Finding. Through these mitigation measures,
developers will limit the intensity and duration of noise
exposure experienced by existing residences ink, construction
areas. Other mitigations will limit noise exposure by
moving the noise-generating equipment as far away from
residential uses as possible.
IMPACT 3.10~F. Noise Conflicts due to the ~djacenc~ of Diverse
Land Uses P~rmitted .by Plan Policies Supporting Mixed-Use
Development2 The presence of different land use types within the
same development creates the possibility of noise impacts between
adjoining uses, particularly when commercial and residential land
uses abut. .f~DEIR page 3.10-5.
Mitiqation MeasuFe 3.10 / 6.. 0. Development projects in the
RPA shall prepare noise management plans to be reviewed as
part of the development application for all mixed use
projects involving residential uses and non-residential
uses. To be prepared by a qualified acoustical consultant,
the plan should aim to provide a high quality acoustic
environment for residential and non-residential users and
should propose steps to minimize or avoid potential noise
problems. The plan should address the concerns of resi-
dents, non-residential users, and maintenance personnel, and
should .make maximum use .of site planning to avoid noise
conflicts.' DEIR page 3.10-5 to -6.
114\eastd~b \£ind (4) 61
Finding. Changes or alterations have been required in, or
incorporated into, the Project that avoid or substantially
lessen the significant effect identified in the Final EIR.
Rationale for Findinq. The required noise management plans
allow both the developer and the City to anticipate possible
noise conflicts in mixed-use developments and to propose
specific measures to address the specific conflicts identi-
fied. i~Occurring at an early stage in the process and
reviewed with the development application, projects can make
use of-the greatest array of conflict reducing techniques,
including building design and site planning. Compliance
with these mitigations will lessen or avoid potential noise
conflicts from adjacent mixed uses.
I~P~CT 3.1~/A. Dus2 Deposition Soiling Nulsanoe f~om
Construction &ctivity. Clearing, grading, excavation, and
unpaved roadway travel related to project construction will
generate particulate matter which may settle out near the
construction sites, creating a soiling nuisance. Any additional
dust pollution will worsen the air basin's non-attainment status
for particulates. Dust emissions is therefore also a potentially
significant cumulative impact. DEIR page 3.11-3, 5.0-13.
Mitigation Measure 3.11/1.0. Require development projects
in the Project area to implement dust control~-measures,
including but not limited to, watering construction sites,
cleaning up mud and dust carried by construction vehicles,
effective covers on haul trucks, planting, repaying, and
other revegetation measures on exposed soil surfaces,
avoiding unnecessary idling of construction equipment,
limiting on-site vehicle speeds, and monitoring particulate
matter~ilevels. These measures will reduce project dust
deposition to acceptable levels, but will not avoid
cumulative impacts of dust generation. DEIR page 3.11-3 to
-4, 5.0-13.
Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, cumulative dust generation impacts will not be
substantially avoided. Therefore, a Statement of Overriding
Considerations must be adopted upon approval of the Project.
Rationale for Findinq. The mitigation .mea=ures identify
various, feasible and reasonable dust control measures that
.developers can take during construction activity. These
measures eliminate and/or minimize the amount and effect of
dust deposition in construction areas. Even with these
measures, however, some small amount of additional pollution
will occur. Therefore, the cumulative impacts of dust
emissions cannot be fully mitigated.
ll4\eas%dub\~ind (4) 62
IMPACT 3.11/B. Construction E~uipment/Vehicle ~m~ssions.
Construction equipment operation generates daily exhaust
emissions. Normally considered a temporary impact, buildout of
the Project area over the long term will be a chronic source of
equipment/vehicle emissions. This is also a potentially signifi-
cant cumulative impact due to the non-attainment status of the
air basin. DF. IR page 3.11-4, 5.0-13.
Mitiqation ~easures 3.11/2.0 to 4.0. Minimize construction
interference with regional non-Project traffic movement by
scheduling and routing construction traffic to non-peak
times and locations. Provide ride-sharing incentives for
construction personnel. Require routine low-emission tune-
ups for on-site equipment. Require development projects in
the Project area to prepare a Construction Impact Reduction
Plan incorporating all proposed air quality mitigation
strategies with clearly defined responsibilities for plan
implementation and supervision. DEIR page 3.11-4, 5.0--13.
Finding. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for Findinq. The mitigations include, construction
timing and siting measures that will reduce equipment and
vehicle emissions over the long-term buildOut of the
Project. Even with these mitigations, howevers, neither
Project nor cumulative air quality impacts can. be fully
mitigated.
IMPACT 3.11/C. Mobile Source Emissions: ROG or NOx. Project
implementation at full buildout will generate 500,000 daily
automobile trips within the air basin. Mobile source emissions
for ROG and:NOx associated with these vehicle trips are
precursors to ozone formation. The emissions associated with
this level of vehicle use will far exceed BAAQMD thresholds for
significantSeffect. This is also a potentially significant
cumulative impact. DEIR page 3.11-5, 5.0-14.
Mitigation Measures 3.11/5.0 to 11.0. Exercise interagency
cooperation on a subregional and regional basis to integrate
local air quality planning efforts with transportation,
transit and other infrastructure plans. Implement techni-
ques, such as transportation demand management (TDM),
shifting travel to non-peak periods, and encouraging mixed-
use development which provides housing, jobs, goods and
services in close proximity as a means of reducing vehicle
trips and related emissions and congestion. At the
development Project level, maintain consistency between
114 \eastdub\fhd (¢)

specific development plans and regional transportation and
growth management plans, coordinate levels of growth with
roadway transportation facilities and improvements, and
require linkage between housing growth and job opportunities
to achieve a positive subregional jobs/housing balance.

incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for Finding. The various techniques described in
the mitigation measures provide opportunities to reduce
vehicle trips, and therefore reduce vehicle emissions.
However, because of the size of this Project, neither
Project nor cumulative impacts can be fully mitigated.
IHP~CT 3.1~/E. Stationar~ Source Emissions. Specific Plan
buildout will create emissions from a variety of sources,

Findinq. Changes or alterations have been required in, or
incorporated into the Project. However, even with these
changes, the impact will not be avoided or substantially
lessened. Therefore, a Statement of Overriding Considera-
tions must be adopted upon approval of the Project.
Rationale for Findinq. Focusing on reducing emissions from
various sources will allow an incremental reduction in
stationary source emissions. These reductions will not,
however, be sufficient to avoid either Project-related or
cumulative impacts.

Section $
FINDINGS CONCERNING ~LTERNATIVES
The City Council is adopting Alternative 2 (with minor changes)
described in the Final EIR in place of the originally proposed
Project. The City hereby finds the remaining three alternatives
identified and described in the Final EIR were considered and are
found to be infeasible for the specific economic, social, or
other considerations set forth below pursuant to CEQA Section
21081, subdivision (c). The City also declines to adopt the
Project as originally proposed for the reasons set forth below.
THE ORIGINALLY PROPOSED PROJECT.
Section 21081, subdivision (c) does not require the City Council
to make findings as to why the originally proposed Project was
not adopted. Such findings need only be made as to project
alternatives which would mitigate significant environmental
effects. Alternative 2 has no significant, envirorunental effects
which could be avoided by adopting the originally proposed
project in its stead. Rather, the city Council finds that
Alternative 2 will pose no significant environmentaleffects that
would not be posed at.least ~o the same extent (and'often to a
greater extent) by the Project as originally proposed.
Public:Resources Code section 21085 prohibits, public
agencies from reducing the proposed number of housing units as a
project alternative pursuant to CEQA for a particular significant
affect on the environment if it determines that there is another
feasible specific mitigation measure or project alternative that
would provide a comparable level of mitigation. The Project as
adopted does indeed involve a reduction of the number of housing
units than were originally proposed, both because the Project as
adopted does not provide for residential development in the
Livermore Municipal Airport Protection Zone and because the
Project as adopted only involves residential development
approximately two-thirds of the area originally proposed for
development. Moreover, these reductions do result in mitigation
of some significant environmental impacts, especially impacts on
Doolan Canyon.
The prohibition of residential development within the
Livermore Municipal Airport Protection Zone is adopted in order
to comply with Public Utilities Code section 21676 azld the
decision of 'the Alameda County Airport Land Use Commission
pursuant to that action to prohibit residential development in
114 \eastdub\find (4) 66
the Zone. This prohibition is, thus, not adopted merely as a
mitigation measure pursuant to CEQA.
The City also finds that no feasible alternatives or
mitigation measures will provide the level of mitigation of
significant environmental effects as are provided by the adoption
of Alternative 2 rather than the project as originally proposed.
Alternative 2 will leave Doolan Canyon in its current largely
undeveloped state, thereby mitigating significant impacts
involving loss of open space, and biologically sensitive habitat
in a way that could not be accomplished by any mitigation measure
or alternative were Doolan Canyon in fact developed as originally
proposed.
ALTERNATIVE 1: NO PROJECt. DEIR pages 4-1 to 4-8, 4-20
Finding: Infeasible. This option assUmes the Project as proposed
would not be built on the site'; instead any development would be
pursuant to ,the existing general plan. Under that plan, a
limited amount of business park/industrial development could
occur on the 600 acre County property and on the 200 acre portion
of the Project area south of the proposed Dublin Boulevard
extension. '
The No Project Alternative is found to be.infeasible because the
City's General Plan has designated the Eastern Dublin area for
planned development, subject to the preparation of a Specifi6
Plan. In addition, the No Project Alternative fails to provide
needed housing. The need for housing is docUmented in the
Housing Element of the city's General Plan, and in o~her plan
documents of the city and other jurisdictions in the area.
~LTEItN~TIVE 3: REDUCED LAND USE INTENSITIES.
DEIR pages 4-14 to 4-19
Findinq: Infeasible. This option assumes development of both the
Specific Plan and the General Plan Amendment except that 285
acres of higher traffic generating commercial uses will be
replaced with lower traffic generating residential uses. The
Reduced Land Use Intensities alternative is found to be
infeasible for the following reasons:
(1)
Airport Safety. This alternative will increase the number
of housing units within the Livermore Municipal Airport
Protection Zone. (p. 4-15).
(2)
Unavoidable impacts. Even with the reduced intensities of
this alternative, all the unavoidable impacts identified for
the Project would remain except traffic impacts at 1-580, I-
680/Hacienda, at 1-580, Tassajara/Airway, at Airway

67
Boulevard/Dublin Boulevard and cumulative traffic impacts on
Dublin Boulevard (Impacts 3.3/B, C, J, and M). DEIR Page 4-
15.
(3)
Fiscal impacts. This alternative may have potentially
significant fiscal impacts on the City budget's cost/revenue
balance by reducing commercial development which generally
generates less service costs and more property tax revenues
than housing. These potential impacts can be mitigated.
However, any mitigating revenues raised would have to be
shared .mitigation for capital facilities, possibly reducing
the amount of revenue available for both the budget and
capital 'facility programs. (page 4-19, 3.12-2 to -4).
ALTEP/TATIFE 4: NO DEVELOPMENT. DEIR page 4-19
Finding: Infeasible. This alternative assumes no development of
the Project.site beyond existing conditions, assumes no annexa-
tion and therefore no application of even the current General
Plan. The No Development alternative is found to be infeasible
because the City's General Plan has designated the Eastern Dublin
area for planned development, subject to the preparation of a
Specific Plan. In addition, the No Development Alternative fails
to provide needed housing. The need for housing is documented in
the Housing Element of the City's General Plan, and in other plan
documents of the City and other jurisdictions in th~ area. (page
4-19 to -20).

ST~TEHENT OF OVE~R~D~N~
1. General.
Pursuant to CEQA Guidelines section 15093, the City Council of
the City of Dublin makes the following Statement of Overriding
ConsideratiOns.
The City Council has balanced the benefits of the eastern Dublin
Project to the City of Dublin against the adverse impacts
identified in the EIR as significant and potentially significant
which have not been eliminated or mitigated to a level of
insignificance.
The city Council, acting pursuant to CEQA Guidelines Section
15093, hereby determines that the benefits of the Project
outweigh the unmitigated adverse impacts and the Project should
be approved.
The City Council has carefully considered each impact in reaching
its decision to adopt the Project and to allow urbanization of
the eastern]Dublin Project area. Although the City'Council
believes that many of the unavoidable environmental effects
identified in the EIR will be substantially lessene~ by mitiga-
tion measures incorporated into the General Plan Amendment,
Specific Plan, and future development plans as well as future
mitigation measures implemented with future approvals, it
recognizes that the implementation of the Project carries with it
unavoidable adverse environmental effects.
The city Council specifically finds that to the extent that the
identified adverse or potentially adverse impacts have not been
mitigated to acceptable levels, there are specific economic,
social, environmental, land use, and other considerations which
support approval of the Project. The city Council further finds
that any one of the overriding considerations identified herein-
after in subsection 3 is sufficient basis to approve the Project
as mitigated.
Z. Unavoidable Siqnificant Adverse Impacts
The following unavoidable significant environmental impacts are
associated with the proposed Project as identified in the Final
Environmental Impact Report for the Project, which consists of a
Draft Environmental Impact Report, Parts I and II (Appendix),
dated August 28, 1992; Comments and Response to Comments, dated
114 \eastdub\find (4) 69
December 7 and December 21, 1992; letter of December 15, 1992
from DKS Associates to Laurence Tong; and the Addendum to draft
EIR dated May 4, 1993. These impacts cannot be fully mitigated
by changes or alterations to the Project.
Land Use Impact 3.1/F. ~mulative Loss of.Agricultural and Open
SDace Lands. Even with mitigation, the Project would still
result in the loss of a large area of open space. This loss is
cumulatively significant, given the loss of numerous other, areas
of open space in the area. No feasible mitigation measures are
available to reduce this impact to a level of insignificance.
The only Project alternatives which could reduce this impact to a
level of insignificance are the No Project Alternative and the No
Development Alternative, both of which have been found to be
infeasible (see Section 3 above). RC ~34-9.
Traffic ~nd Circulation Impact 3.3/B: 1-580 Freeway, 1-680-
Hacienda. Even with mitigation, the Level of Service on 1-580
between 1-680 and Dougherty Road could exceed Level of Service E,
the minimum acceptable level of service. No feasible mitigation
measures are available to reduce this impact to a level of
insignificance, since the freeway has already been widened to its
maximum practical capacity. Project alternatives which could
reduce this impact to a level of insignificance are the No
ProjeCt Alternative and the No Development Alternative. These
alternatives have been found to be infeasible (see?S~ction 3
above). (DEIR pages 3.3-21, 5.0-16). "'
Traffic and!:Circulation Impact 3.3/E: Cumulative Freeway Impacts.
Even with mitigation, portions of 1-580 will operate at Level o~
Service F.under the Cumulative Buildout with Project scenario. No
feasible mitigation measures are available to reduce this impact
to a level of insignificance. The only Project alternative which
could reduce this impact to a level of insignificance is the No
Development Alternative. This alternative has been found to be
infeasible (see Section 3 above). (DEIR pages 3.3-22, 5.0-16)
Traffic and Circulation ?mDact 3.3/I: Santa Rita Road and 1-580
Eastbound Ramps. Year 2010 development with the Project will
cause Level of Service F operations at this intersection. No
feasible mitigation measures are available to reduce this impact
to a level of insignificance. Project alternatives which could
reduce this impact to a level of insignificance are the No
Project Alternative and the No Development Alternative. These
alternatives have been found to be infeasible (see Section 3
above) . (DEIR pages 3.3-26, 5.0-16)
Traffic and~Circulation Impact 3.3/M: Cumulative Impacts on
Dublin Boulevard. Cumulative Buildout with the Project will
cause Level:!of Service F operations at the Hacienda Drive
intersection and Level of Service E operations at the Tassajara
114 \eab-t:dub \:~incl ( · ) 70
Road intersection. No feasible mitigation measures are available
to reduce this impact to a level of insignificance. Project
alternatives which could reduce this impact to a level of
insignificance are the Reduced Land Use Intensities Alternative
and the No Development Alternative. These alternatives have been
found to be-infeasible (see Section 3 above). (DEIR pages 3.3-
27, 5.0--16),
Community services and Facilities Impact 3.4/Q: Demand for
Utility Extensions. The extension of gas, electric and telephone
service lines onto the Project site is necessary for development
and will require new distribution systems or substantial exten-
sions of existing systems onto undeveloped lands currently in
agricultural and open space uses. No feasible mitigation
measures are available to reduce this growth inducing impact to a
level of insignificance. Project alternatives which could reduce
this impact to a level of insignificance are the No Project
Alternative and the No Development Alternative. These
alternatives have been found to be infeasible (see Section 3
above). (DEIR pages 3.4-24, 5.0-16).
Community services and Facilities Impact 3.4/S: Consumption of
Non-Renewable Natural Resources. Natural Gas and electrical
service would increase consumption of non-renewable natural
resources. 'Requiring energy conservation plans provides partial
mitigation. However, because energy use will still, increase, the
impact cannot be reduced to a level of insignificance. Project
alternatives which could reduce this impact to a level of
insignificance are the No Project Alternative and the No
DevelopmentAlternative. These alternatives have been found to
be infeasible (see Section 3 above). DEIR page 3.4-25.
Sewer, Water, and Storm Drainaqe Impact 3.5fF,H,U: Increases in
Enerqy Usage Throuqh Increased Water Treatment and Disposal and
Thorough Operation of the Water Distribution System. Increased
Wastewater Flows to and from the Project will require increased
energy. Using energy efficient water distribution treatment, and
disposal systems provides partial mitigation. However, because
energy use will still increase, the impact cannot be reduced to a
level of insignificance. Project alternatives which could reduce
this impact~to a level of insignificance are the No Project
Alternative':and the No Development Alternative.. The~e alterna-
tives have ~een found to be infeasible (see Section 3 above).
DEIR pages 3.5-8 to -10.
Sewer, Water and Storm Drainaqe Impact 3.5fT: Inducement of
Substantial~Growth and Concentration of Population. The proposed
water distribution system will induce significant growth in the
Project area. No feasible mitigations are available to reduce
this impact to a level of insignificance. The only Project
alternatives which could reduce this impact to a level, of
ll4\eastdub\ find (4)
71
insignificance are the No Project alternative and the No
Developmentialternative. These alternatives have been found to
be infeasible (see Section 3 above). (DEIR, pages 3.5-20, 5.0--
15) .
Soils, Geol°qy, and Seismicity Tmpact 3.6/B: Earthquake Ground
ShakinG, Primary_ Effects. Development of the RPA will expose
more residents to the risk of potentially large earthquakes on
active fault zones in the region, which could result in damage to
structures and infrastructure and, in extreme cases, loss of
life. Using modern seismic design for resistance to lateral
force in construction of development projects, and building in
accordance with the Uniform Building Code and applicable local
code requirements will partially mitigate this impact. However,
the ~mpact cannot be reduced to a level of insignificance. The
only Project alternative which could reduce this impact to a
level of insignificance is the No Development alternative. This
alternative has been found to be infeasible (see Section 3
above). (DEIR page 3.6-7.)
Bioloqical Resources Tmpact 3.7/C: Loss or Deqradation of
BotanicallylSensitive Habitat. Development of the RPA will
result in a'~significant loss and degradation of biologically
sensitive habitat. As described in section 1, mitigation
measures will partially reduce this impact. However, because
biologicallY sensitive habitat will still be lost,~the impact
cannot be reduced to a level of insignificance. The only Project
alternative which could reduce this impact to a level of
insignificance is the No Development alternative. .-This
alternative has been found to be infeasible (see Section 3
above). (DEIR pages 3.7-10, 5.0-11).
Visual ImDacts 3.8/B: Alteration of Rural/Open Spaoe Visual
Character and 3.8/F: Alteration of visual Character of Flatlands.
Project development will permanently alter the existing rural,
agricultural character of the Project area. Although the highest
ridgelines will be preserved as open space, the visual character
of the rounded lower foothills along 1-580 will be altered by
constructio~ of homes and roads. No feasible mitigations are
available to reduce these visual impacts to a level of insignifi-
cance. The'only Project alternative which could reduce these
impacts to a level of insignificance is the No Development
alternative;' This alternative has been found to be infeasible
(see Section 3 above). (pages 3.8-5, -7, 5.0-17).
Noise Impact 3.10/B: Exposure of Existinq Residences to Future
Roadway Noise. Increased traffic on area roadways will
significantly increase noise levels, thus adversely affecting
existing residences and population. Mitigation can be achieved
to buffer residents from levels that exceed acceptable standards,
by providing berms or walls adjacent to outdoor use spaces of
! 1~, \eastdub\find (4)
72
existing residences. However, the magnitude of change in the
noise environment, from quiet rural roads with little traffic to
busy suburban thoroughfares, cannot be avoided. Project
alternatives which could reduce this impact to a level of
insignificance are the No Project Alternative and the No
Development Alternative. These alternatives have been found to
be infeasible (see Section 3 above). (DEIR page~ 3.10-3 to 4,
5.0-16) .
Noise Impact 3.10/D: Exposure of Proposed Residential Development
to Noise from Future Military Traininq Activities at Camp.Parks
and frQ~ the County Jail. Residential development in the
Specific Plan area would be within 6000 feet of Camp Parks and
the County Jail and could be exposed to noise from gunshots and
helicopter overflight. Mitigations calling for noise studies may
not be feasible at all locations; therefore this impact might not
be reduced to a level of insignificance. Project alternatives
which couldreduce this impact to a levelof insignificance are
the No Project Alternative and the No Development Alternative.
These alternatives have been found to be infeasible (see Section
3 above). (page 3.10-4, 5.0-16).
Air Quality~.Impacts 3.11/A.B.C.E. Project development will have
a potentially significant cumulative impact on air quality as a
result of dUst deposition, construction equipment emissions,
mobile source emissions of ROf and NOx, and stationary source
emissions. While some measures have been adopted to partially
mitigate these impacts, the impacts remain potentially signifi-
cant, especially given the region's existing non-compliance with
air quality standards. The only Project alternative which could
reduce these impacts to a level of insignificance is the No
Development alternative. This alternative has been found to be
infeasible (see Section 3 above). (DEIR pages 3.11-3 through -
6, 5.0-13 through -16.)
3. Overriding Considerations
The City council has considered the public record of proceedings
on the proposed Project and does determine that approval and
~mplementation of the Project would result in the following
substantiali, public benefits.
Economic considerations. Substantial evidence is included in the
record demonstrating the economic benefits which the City would
derive from implementation of the Project. Specifically, the
Projec% will result in:
The creation of about 28,200 new jobs in the Specific Plan
area alone, and a substantial number of construction jobs.
b. Increases in sales revenues for the City.
114\eastdub\ f~'nd(4)
73
c. Substantial increases in property tax revenues.
Social Considerations. Substantial evidence exists in the record
demonstrating the social benefits which the City would derive
from the implementation of the Project. Specifically, the
Project will result in:
Se
be
Increases in housing opportunities in the City and in a
region where housing is costly and in short supply.
IncreaSes in the ~mount of affordable housing in the
An arrangement for the City to contribute its fair share of
regional housing opportunities.
d. Provision of upper-end executive housing in the City.
Other Considerations. Substantial evidence exists in the record
demonstrating other public benefits which the City would derive
from implementation of the Project. They include:
Comprehensive planning incorporating innovative and
extensive environmental premitigation measures not usually
found in projects of this type.
Designating substantial areas of land for Open,Space and low
intensity Rural Residential uses. This includes a potential
regional trail system link through the open space of the
Project site. This open space will conserve 'the ecological
values:of the site and surrounding areas and provide
recreational and open space amenity opportunities for
residents of the Project, the city, and the region. 3.4-

MITIGATION MONITORING PLAN
EASTERN DUBLIN SPECIFIC PLAN/GENERAL PLAN AMENDMENT
The State of California now requires public agencies to adopt a mitigation monitoring program for
changes to the project or conditions of approval which have been identified and adopted as methods
to reduce environmental impacts. Thus with the certification of the Eastern Dublin EIR and adoption
of the Specific Plan and General Plan Amendment, the City ot' Dublin is required to establish a
mitigation monitoring program for all approved mitigation measures.
In order to ensure Lkat all adopted mitigation measures are implemented in a _timely fashion, the
Mitigation Monitoring Program provides the following information for each measure:
has the mitigation measure been recommended?
· Who is responsible for implementing the mitigation?
· What is the mitigation measure being monitored and how?
When. should mitigation monitoring be undertaken? What schedule is required?
Completign: when should the mitigation measure be in place and monitoring be
completed?
Verification,: what agency is required to ensure that the mitigation measure was
implemented?

REVISIONS TO DEIR TEXT ON PAGES 3.3-19 TO 3.%28
IMPACTS AND MITIGATION MEASURES: DAILY TRAFFIC VOLUMES (YEAR 2010
WITHOUT PROJECT)
Daily traffic volumes on various freeway and street segments were projected for Year 2010
conditions without and with the Project, and for cumulative buildout conditions with the Project
(Figure 3.3-E). These volumes were compared to estimated daily capacities of each type of
roadway, as described in Table 3.3-1. The resultant levels of service were estimated based on
the daily traffic volumes (Table 3.3-9).
IM 3.3/A 1-580 Freeway, Tassajara-Fallon
Year 2010 growth without the Project would cause freeway volumes to exceed level of scm, ice
E on 1-580 between Tassajara Road and Fallon Road. This is a significant cumulative impact.
Mitigation Measure of the EIR ..
MM 3.3/1.0' Caltrans, in cooperation with local jurisdictions, could construct
auxiliary lanes on 1-580 between Tassajara Road and Fallon Road to
provide a total of I0 lanes in that section, consistent with the Caltrans
Route Concept Report for 1.580.
Implementation of MM 3.3/1.0 would provide LOS D operations and reduce the impact to a

(~omment: Methodoloe~ for Analysis of Traffic lmnacts. This report does not nnalyze the
proposed project's impact to traffic on freeway corridors and ramp intersections in an
acceptable manner. AM peak hour and PM peak hour traffic volumes should be used as a
basis in analysis rather than daily traffic volumes.
~esoonse to Comment 12-1: Peak hour traffic volumes (P.M.) were used in the analysis of
all freeway ramp intersections (see Table 3.3-10, page 3.3-24).
As shown in Table 3.3-7 on page 3.3-14, 47 percent of the Project's trip generation would be
attributable to retail land uses. Retail land uses generate little of their trai'fic during the A.M.
peak hour, about 25 percent of the traffic they generate during the P.M. peak hour.
Therefore, the overall Project trip generation would be about 30 percent lower during the
A.M. peak hour compared to the P.M. peak hour. It was determined that the P.M. peak hour
would be the most critical period for traffic analysis.
Freeway volumes were evaluated on a daily basis, consistent with the daily traffic volume data
published by Caltraz~. Directional peak hour traffic volumes have not been published by
Caltrans for the freeway segments adjacent to the Eastern Dublin Project.
Comment: I-~80 Imnrovements. The fifth auxiliary lane between Dougherty/Hopyard Road
in each direction of I-Sg0 has not been added az of today. These auxiliary lanes will be
included in BART's roadway reconstruction which is scheduled to begin in mid-1993.
R~snonse to Comment 12-2: The fifth auxiliar~ lane will be added prior to the 2010 analysis
year. The analysis of project impacts in Table 3.3-9 assumed the correct number of .lanes.
The analysis of existing conditions for the segment of 1-580 between Dougherty
Road/Hopyard Road and Hacienda Drive is incorrect. The existing level of service on this
freeway segment would be "D' rather than 'C~. Corresponding revisions to text and tables are
included as an attachment to this Final EIR.
~omment: Road Seements. In Table 3.3-2:1992 Existing Freeway Operations, the number
of lanes west of Hacienda Drive should be eight, not ten.
Resoonse to Comment 12-3: See response to Comment 12-2.
Comment:. Freeway Operations. In Table 3.3-9:. Freeway Operations, the number of lanes just
west of 1-680 (between San Ramon/Foothill Road) should be ten. West of Hacienda, the
number of lanes should be eight.
~'gsDonse to Comment 12-4: As noted in the comment, a fifth auxiliary lane for merging and
weaving is now provided in each direction on 1-580 west of 1-680 between Foothill/San
Ramon and 1-680, for a total of ten lanes (eight through lanes, two auxiliary lanes).
Corresponding revisions to Table 3.3-9 are included az an attachment to this Final £IR. The
revised number of lanes on 1-580 west of 1-680 would not cause a change in Project impacts
or mitisatio~.
As noted in the comment, there are currently eight lanes on 1-580 west of Hacienda between
Dougherry/'Hopyard and Hacienda Drive. Corresponding revisions to Table 3;3-9~ for the
existing conditions are included as an attachment to this Final ErR. This section of 1-580 has
been programmed for construction to provide a total of ten lanes (eight through lanes, two
12-5
12-6
12-7
12-8
auxiliary lanes) as part of the current BART extension construction project. These lanes will
be completed prior to 2010. The analysis of Project and Cumulative impacts on this section
of 1-580 assumed the correct number of lanes which will exist at that time.
(~ommen~ Proportionate ~hare. The EIR recommends (MM 3.3/4.0) "the projec! should
contribute a proportionate share to planned improvements at the 1-580/I-680 interchange...'.
Please explain what the proportionate share would be based on, and also describe the
procedure which would ensure that the Project will contribute its share.
Response to Comment 12-5: The proportions of improvement costs to be paid by various
jurisdictions and developments should be based on a regional study of improvement needs,
such as the current study by the Tri-Valley Trnn-~portation Council. The shares of
improvement costs should also consider prior contributions to regionnl road improvements.
The City of Dublin is participating in regional studies of future transportation requirements
(Tri-Valley, Alameda Count'y) and would establish a fee structure to ensure future
development pays for the appropriate share of regional road improvements based on those
regional studies.
Comment Imnact of the Project on Existin~ Intersections. The level of service and average
vehicle delay of PM peak hour intersection operations are listed without mitigation. Because
this proposed development is mainly residential, the impact of projected traffic on existing
intersections caused by the morning commute (AM peak) should also be considered. Any
intersection in which the LOS will become unacceptable during the AM peak will need
mitigation.
Response to Comment 12-6: See the response to Comment 12-1. As noted, nearly half of the
Project's daily trip generation would be attributable to retail land uses, which generate about
75 percent fewer trips during the A.M. peak hour compared to the P.M. peak hour.
Therefore, the overall Project traffic generation would be about 30 percent lower during the
A.M. peak hour compared to the P.M. peak hour. It was determined that the P.M. peak hour
would be more critical for traffic nnnlySis than the A.M. peak hour. However, recommended
road improvements propose balanced lanes in each direction to ensure that reverse direction
traffic flows can be accommodated during other time periods.
Comment:. Ramp Meterint. The operation of at least five interchanges on 1-580 and two
interchanges on I=680 will be affected by the Project. It is recommended that ramp metering
be considered for all the on-ramps within the Project limits. The proposed on-ramp
improvements should provide adequate storage to accommodate the ramp metering operation.
The improvement of local streets needs to be considered to accommodate the ramp metering.
ResPonse to Comment 12-7: l~mp metering would control vehicles entering the freeway on
on-ramps, to ensure that waffic on the mainline freeway operates smoothly during peak
periods. Ramp metering reduces delay on the mainline freeway, but increases delay for
drivers on local streets wishing to access the freeway. If designed properly, ramp metering
can reduce the wtal overall delay for all drivers. The City of Dublin will coordinate with
Caltrans on all interchange improvements to ensure that ramp metering can be accommodated.
Comment: Coordination of Sienalization of Ramps and Intersections. There are several
signalized ramp intersections and local street intersections within the project limits. Usually,
the signals on local streets are designed and operated independently by local authorization.
However, in order to operate the interchanges which will be affected by this project more
efficiently, the signal interconnection between ramp intersections and local street intersections
is essential. The coordination between the State and local authorization to design and operate

The California Department of Transportation (Cattrans) has reviewed
the above-referenced document and forwards the following comments:
This report does not analyze the proposed project's impact to traffic
on freeway corridors and ramp intersections in an acceptable manner. AM Iz-1
peak hour and PM peak hour traffic volumes should be used as a basis in
analysis rather than daily traffic volumes.

Please explain what the proportion would be based on, and also describe I
the procedure which would ensure that the project will contribute its
share.
The level of service and average vehicle delay of PM peak hour --'~
intersection operations are listed without mitigation. Because this
proposed development is mainly residential, the impact of projected tz--6
traffic on existing intersections caused by morning commute (am peak) j
from this new development Should also be considered. Any intersection, in
which the level of service will become unacceptable during the am peak,
will need mitigation.
The operation of at least five interchanges on Route 580 and two
interchanges on Route 680 will be affected by this proposed project. It is

(~omment: Inter]urisdicti0nal Cooueration. East Dublin, Dougherty Valley and Tassajara
Valley share a common location, a common need for expansion of infrastructure, and a
common time frame for development. Because of these common traits, the planning agencies
should work together to coordinate expansion of public services and facilities, and to find
solutions to common problems.
ResDonse to Comment 13-1: Comment acknowledged.
Comment: Coordinated Subrenional Transit Plan. TVPOA suggests that eastern Dublin
developers be required to cooperate with adjacent property owners (TVPOA and Dougherty
Valley) as well as adjacent business parks (Hacienda and Bishop Ranch) and the nearby
regional shopping mall (SWneridge) to explore the feasibility of a sub-regional transit system
to serve the area. This effort should be done in cooperation with the Central Contra Costa
Transit Authority, Livermore-Amador Trnnzit Authority, and BART. It may be that such an
effort can be accomplished in conjunction with the TVTC planning study.
Resvonse to Comment 13-2: Comment acknowledged. Mitigation measures MM 3.3/15.0
through MM 3.3/15.3, page 3.3-28 of the DEER, recommend that the City of Dublin
coordinate with tr~_n.~it service agencies and that the Project contribute a proportionate share
to the cost of transit service extensions. The City of Dublin is also participating in the Tri
Valley Transportation Council study, which will recommend transportation improvements on
a regional basis.
Comment: Land Use Assumptions for Tassajara ValleY. The Final ErR should reflect current
projections for total buildout and timing of development in Tassajara Valley. Current plans
call for 6, 100 dwelling units and 350,000 square feet of commercial/office space which would
yield 700 employees. This update may require modifications to the cumulative traffic analysis
in those areas most impacted by trips generated by Tassajara Valley development, i.e.,
Tassajara Road.
Resnonse to'Comment 13-3: The analysis of Project traffic impacts in the DEIR was based
on ABAG Projections of land use for the Bay Area. These 2010 projections of overall land
use in each census tract are based on an assessment of regional growth and absorption
potential of new land uses, and would not change significantly as a result of changes in the
ultimate projected buildout of each individual development project such as Tassajara Valley.
The Cumulative Buildout analysis in the DEIR assumed development levels in Tassajara
Valley consistent with the application for a General Plan Amendment submitted to Contra
Costa County, the most current publicly available document at the time of the analysis for the
DEIR. Future traffic studies conducted for the Tassajara Valley development should address
the traffic impacts of changes in potential development levels in Tnssajara Valley compared
to the initial GPA application.
Comment: Cumulative Traffic Impact on Tassaiara Road. The Draft ErR concludes that
development outside Eastern Dublin, primarily in Dougherty and Tassajara Valleys, will cause
level of service F operations at three Tassajara Road intersections in the Eastern Dublin
planning area. The Draft EIR determines that thi_~ impact can be mitigated by widening
Tassajara Road (MM 3.3/14.0, page 3.3-28). Yet, the Draft E1R falls short of recommending
this mitigation measure. Instead, the Draft EIR Ieaves open the-possibility that Tassajara road
will remain four lanes despite concluding that to do so would result in a significant impact.
Attempting to maintain Tassajara Road as a four lane road would seem to be inconsistent with
13-5
13-6
13-7
a regional vision of the problem.
Re~nonse to Comment 1)-,~: See Response to Comment 5-2. The City of Dublin is
considering recommending a revision to the Specific Plan to reserve right-of-way for six lanes
on Tassajara Road between Dublin Boulevard and Gleason Road.
Comment: Extension of Hacienda Dri,~ ~9 Deu~her~ Valle~. One solution to the traffic
congestion problems projected for Ta.~ajara Road is the extension of Hacienda Drive north
into the Dougherty Valley.
Dougherty Road is incapable of handling the entire vehicle traffic volume from new
development in Dougherl3, Valley. To help solve this problem, Windemere Parkway is
extended from the east side of Dougherty Valley east to Camino Tassajara in Tassajara Valley.
This route will provide a primary, yet indirect, access to 1-580 via Tassajara Road, but will
also increase the volume of traffic on Tassajara Road and at the 1-580 interchange almost to
a breaking point assuming development in Tassajara Valley and East Dublin.
An extension of Hacienda Drive north into Dougherty Valley would provide direct access
routes to 1-580 for the west and east sides of Dougherty Valley and Tassajara Valley, and thus
would balance the traffic loads at the 1-580 interchanges and through Dublin and East Dublin.
Also, a Hacienda Drive extension provides a direct link for the entire Dougherty Valley to the
following: 1) the new BART station planned near Hacienda Drive and 1-580; 2) the heart of
Hacienda Business Park in Pleasanton, and 3) the new commercial and office uses planned for
the County property in the East Dublin Specific Plan.
Extending Hacienda Drive into Dougherty Valley is a positive step that will alleviate problems
on Tassajara Road. This alternative should be reviewed further in the EIR.
Resuonse to Comment 13-~: Comment acknowledged. The circulation plan for the Eastern
Dublin Specific Plan does not preclude the potential extension of Hacienda Drive north to
DougherW Valley. An extension of Hacienda Drive north is a possibility that has been
explored by both the Dougherty Valley proponents and by the Eastern Dublin planning
consultants. The U.S. Army has indicated that such an extension through Camp Parks would
be inconsistent with the Army's plan for the base, and therefore would not be permitted.
Comment:. (~o0rdinafi0n with the 680/580 Association. The Eastern Dublin Specific Plan
should include provisions to require property owners and developers to coordinate with the
680/580 Corridor Transportation Association and, if appropriate, to develop remote
telecommute centers within the Project area. Also, consideration might be given to the
development of m-called "smart homes' in the study area to faciUtate at-home and/or
neighborhood telecommuting. These concepts could be evaluated to determine the potential
to reduce peak hour and/or total Daily Vehicle Trips.
]~esDonse to Comment 13-6: Telecommuting could help to reduce future traffic volumes, and
should be included as one of the potential components of the Transportation Systems
Management programs included as Mitigation Measure MM 3.3/2.0. Since there is inadequate
existing data available to quantify the potential traffic reductions due to increased
telecommuting, the DEIR conservatively assumed no reduction in traffic.
Comment: Consistency of EIR with Re~,ional Traffic Models. The Final ]~IR should point out
the sim~arities and differences Of the Draft EIR land use assumptions and trip di.n-tribution
model with regional traffic models developed by the Contra Costa Transportation Authority,
the Tri-Valley Transportation Council, and the Alameda County Congestion Management
13=8
Agency, it' available.
Response ~o Comment 1)-7: The traffic model used in the Draft EIR uses the standard
methodology for traffic forecasting, as do the other travel demand models currently being
used for Tri-Valley studies.
The Eastern Dublin analysis uses essentially the same ABAG Projections '90 2010 land use
forecasts for the Tri-Valley area as the current studies by the Contra Costa Transportation
Authority and the Tri-valley Transportation Council. The Alameda County model also uses
ABAG Projections '90, but currently uses an earlier disasgregation of land use data to
individual traffic analysis zones. The earlier disaggregafion did not consider the most recent
development proposals. The Eastern Dublin analysis quantifies non-residential land uses in
terms of square footage, while the other models use employment, so there may be some
differences in the reported employment numbers by jurisdiction because of assumptions used
in the conversion between employment and square footage.
The Eastern Dublin analysis determines traffic generation by relating vehicle trips directly
to land uses. The other models use a standard procedure to estimate the number of person
trips (people coming in and out of each building rather than cars), and then the persons are
allocated to travel modes such as auto driver, auto passenger, or transit passenger. The
resulting number of vehicle trips should be the same using either process.
All of the models use a standard trip distribution process based on data from the Metropolitan
Transportation Commission (MTC). The Eastern Dublin analysis assumes trip distribution
based on unconstrained travel conditions. The other models assume that future trip
distribution will be balanced based on congestion; in other words, in the future, people may
choose to work and shop closer to home because congestion has increased. This procedure
may result in a more realistic analysis of future travel patterns, but is somewhat less
conservative since it will tend to indicate more future trips remaining internal to each
development. The Eastern Dublin analysis also assumes unconstrained growth of traffic
demand over the Altnmont Pass to San Joaquin County, while the other models assume some
type of constraint on traffic demand over the Altamont Pass. Again, the procedures for trip
distribution used in the Eastern Dublin DEIR will tend to provide a more conservative
analysis of future traffic impact~.
Comment; IM }.7/B: Indiregt Imnacts of Vetetafion Removal. The Draft EIR mitigates for
vegetation removal and possible erosion by calling for revegetation with native vegetation
(MM 3.7/5.0). TVPOA suggests expansion of this mitigation in the Final EIR by requiring
verification of physical a:~d biological feasibilit~ of planting locations, including topography,
aspect, soils, hydrologic condition, and potential competition. Also, the native shrubs, herbs,
and grasses should also be local to the Tri-Valley and the plant communities of eastern
Dublin.
Rcsv0nse to Comment 13-g: Comment acknowledged. The following text has been added
to MM 3.7/5.0, on page 3.7-10:
AH areas o/disturbance should be reyegetated as quickly as possible to prevent erosion.
Native trees (preferably those species already on site), shrubs, herbs and grasses should
be used for revegetation of areas to remain as natural open space. The introduction of
