Environmental Checklist/
Initial Study
Project Location and Characteristics ~:~
The project site is located between Starward Drive and San Ramon Road, north of Amador
Valley Boulevard. The site contains approximately 2.4 acres of land which is owned by the
DeSilva Group. The Assessors Parcel Number (APN) for the site is 941-0173-005-02.
Surrounding land uses include an Alameda County Flood Control and Water Conservation
District Zone 7 flood control channel immediately north of the site. North of the flood control
channel single family homes have been constructed. West of the site, San Ramon Road has been
built, with the roadbed elevated approximately seven (7) feet from the project site. A multi-
family housing complex exists west of San Ramon Road. East of the site lies a single story
professional office building and a vacant parcel of land. A major retail commercial shopping
center (Shamrock Center) has been built south of the project site. Exhibit 1 depicts the project
location.
The site is presently flat, having been graded prior to this application being filed. Trees have
been planted along the southerly property line of the site with a small number of other trees
scattered throughout the perimeter of the site. The site has a major expanse of frontage along
Starward Drive and roadway improvements have already been installed adjacent to Starward
Drive, including curb, gutter, sidewalk and street lighting. Existing site elevations are
approximately 362 feet above sea level, although the site does have a slight but distinct slope
toward Starward Drive, which has an elevation of approximately 359 feet above sea level
adjacent to the project site.
Exhibit 2 depicts existing site conditions.
Project Description
The project involves a proposal to amend the City's General Plan, to amend the Downtown
Specific Plan and rezone the project site to allow the development of single family homes on the
site, along with associated improvements typical of a residential development. Exhibit 3 depicts
the proposed General Plan Amendment and Rezoning. Exhibit 4 shows the proposed
Amendment to the Downtown Specific Plan.
The project would consist of thirty-one (31) residential lots and five (5) lettered lots on the site.
A detached single family home would be constructed on each of the lots. Lettered lots "A"
through "F" would be devoted to permanent landscaping within and adjacent to the subdivision
and Lot "E" would be reserved for a private road providing vehicular and pedestrian access into
the project site The road would be 24 feet in width. Exhibit 5 depicts the proposed Vesting
Tentative Tract Map which would subdivide the site, if approved by the City of Dublin.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 2
July 1998
The private road would be constructed in a "U" shaped configuration, with two intersections
along the west side of Starward Drive, as indicated on the Vesting Tentative Map. Residential
lots and associated driveways would then front on the interior private road. Lots sizes are
proposed to be varied, ranging in size from 2100 square feet to 3400 square feet each. Exhibit 6
shows a conceptual site plan for the project.
Dwellings proposed for the site would consist of two-story dwellings, each with an attached two
car garage. Preliminarily, houses would range in size from 1350 square feet to 1663 square feet.
Anticipated sales prices would be in the range.of $275,000 to $325,000.
The proposed project would include grading of the site to promote improved on-site drainage.
The preliminary grading plan indicates that grading would be balanced on the site, meaning that
import of fill material would be required nor would material need to be exported from the site.
The proposed project would also involve construction of related improvements as part of the
subdivision, including underground water, sewer, drainage, natural gas and telecommunication
facilities.
The project developer would install landscaping along the Starward Drive project frontage as
well as the front yards of each dwelling. A landscaped tot lot would be provided on Lot A for use
by residents. Landscaping would be maintained by a Homeowners Association. Exhibit 7 depicts
the conceptual landscape plan for the project.
The project developer anticipates that the entire project would be built in a single phase of
development, with the homes ready for occupancy by Fall, 1999.
To allow the construction of the proposed project, the applicant has requested the following
approvals from the City of Dublin:
· A General Plan Amendment to change the General Plan Land Use Map designation from
"Retail/Office" to "Medium Density Residential (6.1-14.0 dwellings per acre);"
· An Amendment to the Downtown Dublin Specific Plan to delete the project site from the
Specific Plan area;
· A Zone Change from "C-O (Commercial Office)" to "Planned Development (Medium
Density Residential);"
· A PD-Planned Development overlay on the site (confirm);
· Site Development Review (SDR) for 31 single family residences;
· A Vesting Tentative Tract Map to create 31 lots and six lettered lots.
If the approvals described above are granted, the applicants would then apply for encroachment,
grading and building permits from the City of Dublin, necessary utility connection permits from
the Dublin San Ramon Services District and encroachment permits from Alameda County Flood
Control and Water Conservation District 7.

The project would also involve a transfer of real property between the City of Dublin and the
property owner. The City presently owns a small parcel of land approximately 0.03 acre) located
on the west side of the site, adjacent to San Ramon Road. The site is identified on Exhibit 8. This
site was dedicated to the City as a slope easement. It is the intent of the City to declare this site as
surplus and transfer ownership to the DeSilva Group. This transfer would occur prior to or
simultaneously with the consideration of the Vesting Tentative Tract Map. The Starward project
has been designe4J with a retaining wall along a portion of the westerly property line to eliminate
the need for the slope easement.

Environmental Factors Potentially Affected
The environmental factors checked below would be potentially affected by this project, involving
at least one impact that is a "potentially significant impact" as indicated by the checklist on the
following pages.

Circulation
x Population/Housing Biological Resources x Utilities/Service
Systems
X Geotechnical - Energy/Mineral x Aesthetics
Resources
x Water - Hazards x Cultural Resources
x Air Quality X Noise x Recreation
- Mandatory Findings
of Significance
Determination (to be completed by Lead Agency):
On the basis of this initial evaluation:
I find that the proposed project could not have a significant effect on the environment and a
~'egative Declaration will be prepared.
X I find that although the proposed project could have a significant effect on the environment,
there will not be a significant effect in this case because the mitigation measures described on an
attached sheet have been added to the project. A Negative Declaration will be prepared.
~ I find that although the proposed project may have a significant effect on the environment,
but at least one effect 1) has been adequately analyzed in an earlier document pursuant to
applicable legal standards, and 2) has been addressed by mitigation measures based on earlier
analysis as described on the attached sheets, if the effect is a "potentially significant impact" or
"potentially significant unless mitigated." An Environmental Impact Report is required, but
must only analyze the effects that remain to be addressed.
~ I find that although the proposed project could have a significant effect on the environment,
there will not be a significant effect in this case because all potentially significant effects (a)
have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have
been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation
measures that are imposed on the proposed project.

Evaluation of Environmental Impacts
1)
A brief explanation is required for all answers except "no impact" answers that are
adequately supported by the information sources a lead agency cites in the parenthesis
following each question. A "no impact" answer is adequately supported if the referenced
information sources show that the impact simply does not apply to projects like the one
involved (e.g. the project falls outside a fault rupture zone). A "no impact" answer should
be explained where it is based on project-specific factors as well as general factors (e.g. the
project will not expose sensitive receptors to pollutants, based on a project-specific
screening analysis).
2)
All answers must take account of the whole action, including off-site as well as on-site,
cumulative as well as project-level, indirect as well as direct, and construction as well as
operational impacts.
3)
"Potentially Significant Impact" is appropriate if there is substantial evidence that an effect
is significant. If there are one or more "potentially significant impact" entries when the
determination is made, an EIR is required.
4)
"Negative Declaration: Potentially Significant Unless Mitigation Incorporated" implies
elsewhere the incorporation of mitigation measures has reduced an effect from "potentially
significant effect" to a "less than significant impact." The lead agency must describe the
mitgafion measures and briefly explain how they reduce the effect to a less than significant
level.
5)
Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA
processes, an effect has been adequately analyzed in an earlier EIR or negative declaration.
Section 15063 (c) (3) (D). Earlier analyses are discussed in Section 17 at the end of the
checklist.
6)
Lead agencies are encouraged to incorporate the checklist references to information sources
for potential impacts (e.g. general plans, zoning ordinances). References to a previously
prepared or outside document should, where appropriate, include a reference to the page or
pages where the document in substantiated. A source list should be attached and other
sources used or individuals contacted should be cited in the discussion.
7) This is only a suggested form and lead agencies are free to use different forms.

I. Land Use and Planning
Environmental Setting
Existing Land Use
The project site consists of 2.4 acres of vacant land in the central portion of Dublin. The site is
presently vacant and was previously occupied by a single family residence.
Surrounding land uses include a. County Flood Control District open channel and single family
homes to the north, San Ramon Road and multi-family residences to the west, a shopping center
(Shamrock Village) to the south and a single story office and vacant land to the east.
As part of the project, the developer would construct a solid masonry wall along the north, west
and southerly property lines. Although the primary purpose of the wall would be for noise
attenuation, construction of the wall would also provide a land use buffer between the proposed
project and surrounding uses.
Regulatory Framework
Land use and development of property is governed by the'Dublin General Plan, adopted in 1985
and amended since the original adoption date. The General Plan land use classification for the
project site is "Retail/Office", which is intended to promote commercial shopping centers,
service stations, business and professional offices and similar uses. The Retail/Office land use
designation typically does not permit residential uses except in portions of the Downtown area.
Surrounding General Plan land use classifications include "Low Density Single Family
Residential" to the north, "Retail/Office" to the east and south and "Medium Density Residential"
to the west.
One of the primary methods of implementing the General Plan is through the City's Zoning
Ordinance, which regulates land use, building height and setbacks, parking and other
development standards in conformity with the General Plan. The Dublin Zoning Map designates
the project site as "C-O (Commercial Office)," consistent with the General Plan designation. The
C-O district allows a range of retail commercial and office land uses, including but not limited to
banks and financial services, blueprint shops and similar uses. Surrounding zoning designations
include "R-l-B-E-Low Density Residential, Combining District" to the north of the project site;
"Planned Development (Multi-family)" west of the site and "C-l, Retail Business District" south
of the site and "Commercial Office" to the west.

The project site is also included within the Downtown Dublin Specific Plan, which was adopted
in 1987 for the purposes of enhancing the appearance and economical vitality of the downtown
portion of the Dublin.
As part of the proposed project, the applicant has requested a General Plan Amendment and
rezoning to allow the type and density of residential uses proposed for the project. The applicant
has also requested an amendment to the Downtown Specific Plan to exclude the project site from
the boundary of the Specific Plan area. Details regarding the requested General Plan
Amendment, rezoning and Specific Plan Amendment are contained in the Project Description of
this Initial Study.
Project Impacts
a) Conflict with generalplan designation and zoning? PS/M. The proposed project would not be
consistent with the Dublin General Plan, Zoning Ordinance or Downtown Specific Plan as
presently adopted. Although applications have been filed to amend the General Plan, amend the
Downtown Specific Plan and rezone the site, such actions may only be approved by the Dublin
City Council with recommendations on these actions made by the Planning Commission.
Proposed density of the project would be 12.9 dwelling units per acre, which would be consistent
with the Medium Density Residential General Plan land use category, which permits residential
units up to 14.0 dwellings per acre. Similarly, the proposed project is not consistent with the
Commercial Office zoning on the site nor with the intent of the Downtown Specific Plan to
construct office and/or retail commercial uses on the site. There is therefore a potentially
significant impact with respect to consistency with the General Plan, Downtown Specific Plan
and Zoning Map and the following mitigation is recommended to ensure consistency with the
City's General Plan, DowntOwn Specific Plan and zoning ordinance which would reduce this
impact to a level of less than significance.
Mitigation Measure 1: Prior to or concurrently with the approval of the proposed
Vesting Tentative Tract Map for the project, the City of Dublin shall have amended the
General Plan to a Medium Density Residential designation, rezoned the project site to a
Planned Development District and amended the Downtown Specific Plan to exclude the
site from the Specific Plan area.
b) Conflict with applicable environmentalplans or policies? NI. This Initial Study represents full
California Environmental Quality Act compliance with regard to the project. The City of Dublin
has adopted no other city-wide or specific environmental plans or policies which would affect
this application.
c) Incompatibilities with existing land use in the vicinity? LS. The proposed residential
subdivision would be consistent with existing development patterns in the area by extending the
existing single family development pattern south to encompass the project site. Existing
residences north of the project site would be separated from residences on the proposed project
by a distance of approximately 115 feet. In addition, the project developer proposed a solid
barrier wall along the northerly property line to provide an additional buffer between the two
properties. Although potential land use incompatibilities could be created between the proposed
single family development and existing commercial development to the south, the proposed
construction of a solid masonry wall along the southerly property line of the project would
reduce land use impacts to a level of less than significance. No land use compatibility impacts
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013

are anticipated regarding the existing office building to the east, since the majority of dwellings
within the proposed project would have side yards fronting onto Starward Drive. Since the
developer has proposed construction of property line barrier walls as part of the project, no
additional mitigation measures are proposed, ff approved, the project would have the effect of
increasing the resident population near the downtown area, which would assist in furthering
objectives of the Downtown Plan.
d) Effect on agricultural operations or soils? NI. The site has been vacant for a number of years.
and has been slated for commercial or office development. There is no recent history of
agricultural production. No agricultural operations exist on surrounding properties. Therefore, no
impacts are foreseen and no mitigation measures are required.
e) Disruption of physical arrangement of an established community? NI. The project site is
located adjacent to a major shopping center complex to the south, a high speed arterial roadway
(San Ramon Road) to the west and a major flood control facility to the north. It would therefore
not disrupt any existing established community and no impacts are anticipated.
H. Population and Housing
Envirgnmental Se,l/ng
The city population as of January 1, 1996 was estimated by the State Department of Finance to
be 26,267. Significant population growth is anticipated for the community based on planned
residential growth in east Dublin, where the City has approved a specific plan calling for
residential growth.
According to the Association of Bay Area Governments (ABAG), the total population of Dublin
is expected to increase to 35,200 by the year 2000, to 49,400 by the year 2005 and 58,900 in the
year 2010.
Project Impacts
a) Cumulatively exceed official regional or local population projections? LS. The project site is
relatively small in size, approximately 2.4 acres, and would not have an appreciable affect on the
city-wide population base. Based on a person per dwelling unit factor of 3.2 (taken from the
adopted Land Use Element), up to 99 new residents could be located on the site at project build
OUt.
The number of new residents generated by the proposed project would fall within the parameters
of anticipated population growth as outlined in the Environmental Setting section, above.
b) Induce substantial growth in an area, either directly or indirectly? NI. The project site is
considered as an "infill" site and is surrounded by existing single and multi-family development
and commercial development to the south. The site has been slated for office or commercial
development for many years and will therefore not be considered a growth inducing project. No
mitigation measures are required.

c) Displacement of existing housing, especially affordable housing7 NI. The project site is
presently vacant, and no housing units would be displaced. Therefore, no impacts would occur
and no mitigation measures would be required.
HL Soils and Geology
Environmental Setting
[Note: the following information is based on a Geotechnical and Fault Investigation for the site
prepared by Berlogar Geotechnical Consultants, July, 1997.)
Overall geology
The project site is situated within the central part of the Coast Ranges geomorphic provinces,
which is characterized by a series of parallel, northwesterly trending folded and faulted mountain
chains. In this part of the province, the relatively flat Amador Valley is underlain by alluvial
deposits. Folding and faulting of the hills within the region is attributed to the result of
prehistoric tectonic forces causing major uplifts.
Faulting
The Coast Range geomorphic province is seismically dominated by the presence of the active
San Andreas Fault system. The San Andreas Fault system is the general boundary between the
northward moving Pacific tectonic plate and the southward moving tectonic plate. Within this
portion of the Bay area, nearby known active faults include the San Andreas, Hayward and
Calaveras faults. In the immediate vicinity of the project site, the Calaveras fault is located
approximately 100 to 150 feet west of the project site. The Hayward and San Andreas faults lie
approximately 8 and 26 miles, respectively, southwest of the site.
The western portion of the site is located within a State of California designated seismic "Special
Studies Zone" for the Calaveras fault. Recent trenching on the site completed by the applicant's
geotechnical consultant revealed that no traces of possible faulting adjacent to the trench.
Soils
Fill material has been previously deposited on the site. An analysis of the f'fll material indicates
that the material is poorly to well compacted with significant amounts of wood, concrete and
construction debris contained in the fill. Native soils material include alluvium interbeded with
sand, gravel, silt and clay layers. Dark brown clay layers were encountered by the geotechnical
consultant at levels of 4 and 10 feet below surface levels. Moderately expansive soils were
identified on portions of the site.
Liquefaction potential
Liquefaction is the temporary transformation of a saturated, cohesionless soil into a viscous
liquid during strong ground shaking during a major earthquake. Sandy and silty soils
encountered at the site were found to be either dense and stiff or clayey enough to preclude
liquefaction. The geotechnical report rates the risk of liquefaction on the site as low.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 26
July 1998
Pro_iegt Impacts
a) Is the site subject to fault rupture? LS. Although portions of the site are located within a
Special Studies zone for seismic hazard, no evidence of active faulting has been found on the site
by the applicant's geotechnical engineer. The geotechnical report concludes that the risk of
ground rupture from active fault appears low. Dwellings proposed for the site would be required
to comply with seismic requirements established by the Uniform Building Code. Therefore,
based on the geotechnical report, significant impacts are not anticipated and no mitigations are
required.
b) Is the site subject to ground shaking? PS/M. As is true of the majority of sunactures in the Bay
area, dwellings constructed on the project site would be subject to moderate to severe ground
shaking during earthquakes. According to the geotechnical report, the structural integrity of the
proposed buildings would be a primary factor in determining possible seismic damage due to
groundshaking. Groundshaking is a hazard which cannot be eliminated, but can be mitigated to a
level of less than significance based on adherence to the following mitigation measure:
Mitigation Measure 2: All dwellings constructed on the project site shall conform with
Uniform Building Code Standards for Seismic Zone 4.
c) Is the site subject to seismic ground failure? LS. Based on the geotechnical reports prepared
for the project, the risk of ground failure is anticipated to be low. Enforcement of provisions .of
the Uniform Building Code and recommendations contained in the geotechnical report prepared
for the project will serve to reduce potential impacts of seismic ground failure to a less than
significant level. No mitigation measures are required.
d) Is the site subject to seiche, tsunami hazards, including liquefaction? LS. The geotechnical
report prepared for the project concludes that the risk of liquefaction on the site is low. Since the
site is not located adjacent to major bodies of water, there is also very low risk from seiche or
tsunami events and no mitigation measures are required.
e) Is the site subject to landslides or mudflows? NI. The site is relatively flat although moderate
slopes exist along portions of the westerly boundary of the site. Proposed grading for the project
would be constructed in conformance with engineering specifications and recommendations
contained in the geotechnical report for the project as well as Uniform Building Code
requirements. Therefore, any potential impacts from landslides would be considered less than
significant, and no mitigation measures are required.
f) Is the site subject to erosion, changes in topography or unstable soil conditions? PS/M. The
site, as it presently exists, is reasonably flat with a gradual slopes on the westerly side of the
property. A regional open drainage facility exists immediately to north of the site. The applicant
has indicated that the site will be graded in order to provide for future building pads, roads,
parking areas and similar features. Estimated grading quantities would include moving
approximately 4,000 cubic yards of material on the site. Without appropriate mitigation, erosion
could result into the adjacent flood control channel, onto Starward Drive and onto the
commercial property to the south.
The following mitigation measure is proposed to limit impacts related to water-borne erosion.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 27
July 1998
Mitigation Measure 3 The project developer shall prepare and the City shall approve an
erosion and sedimentation control plan for implementation throughout project
construction. The plan should be prepared in accordance with City of Dublin and
RWQCB design standards. The plan, at a minimum, should include the following:
· All disturbed areas should be immediately revegetated or otherwise protected from
both wind and Water erosion upon completion of grading activities;
· Stormwater runoff should be collected into stable drainage channels from small
drainage basins to prevent the build up of large, potentially erosive stormwater fl°ws;
· Specific measures to control erosion from stockpiled earth material;
· Runoff should be directed away from all areas disturbed by construction;
· Sediment ponds or siltation basins should be used to trap eroded soils prior to
discharge into off-site drainage culverts or channels.;
· Major site development work involving excavation and earth moving for construction
shall be done during the dry season, except as may be approved by the City Engineer
Adherence to Mitigation Measure 3 will reduce potential erosion impacts to an insignificant
level.
g) Subsidence of land? LS. Minimal subsidence will occur, according to the preliminary
geotechnical report prepared for the proposed project. No impacts are anticipated and no
mitigation measures are required.
h) Expansive soils? LS. Surficial soils on the adjacent site have been identified as having a
moderate expansive potential. These soils generally tend to shrink, crack and become hard when
dry, and expand and become softer when wet. Expansive soils have the potential to damage
building foundations and other improvements if specific construction techniques are not
followed. The geotechnical report for the project recommends appropriate construction
techniques to ensure that any negative effects of expansive soils can be reduced to a level of
insignificance. No mitigation measures are therefore required.
i) Unique geologic or physical features? NI. None have been identified on the site, based on a
field visit and no mitigation measures are required. Unique geologic features include significant
rock formations, hills and similar features.
IV. Water
Environmental Setting
No surface water exists on the site. The nearest surface water source is an unnamed open flood
control channel which forms the northerly and westerly boundary of the site. This facility has
been constructed by the Alameda County Flood Control and Water Conservation District Zone 7
as a regional drainage facility and continues to be maintained by the District.
According to a representative of Zone 7, the project site, as well as the remainder of the Tri-
Valley area, is underlain by an extensive underground aquifer. The aquifer ranges in depth
between 15 and 500 feet but is no longer used as the primary source of domestic water in the
area. Zone 7 is presently finalizing plans to store treated wastewater within the aquifer during
winter months, which will be pumped out and used for landscape irrigation during dry, summer
months.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 28
July 1998
The Flood Insurance Rate Map (FIRM) prepared for this portion of Dublin indicates that the site
is subject to flooding during 500 year flooding events.
Water is supplied to the community by the Dublin San Ramon Services District (DSRSD),
headquartered in Dublin. DSRSD maintains a variety of facilities to diswibute water throughout
the District's service area. Facilities include reservoirs, water turnouts, pumping stations and
pipelines to deliver water to customers. The District obtains water from an agreement with Zone
7 of the Alameda County Flood Control and Water Conservation District (Zone 7). Zone 7 is a
mtflti-purpose agency that oversees water issues in toe Tri-Valley area, including supplying
treated, water to four retail water agencies, providing flood control protection and managing
underground water resources in the area. Zone 7 presently obtains water from three sources:
State Water Project, local surface water and local groundwater.
Project Impacts
a) Changes to absorption rates? LS. The site is currently vacant and water percolates into the
groundwater table. Development of the proposed project will add impermeable and impervious
surfaces on the site in the form of residences, garages, driveways, walkways and similar hard
surfaces. This will result in higher quantities of storm water runoff which must be accommodated
by the local drainage system. Preliminarily, storm water will likely be directed off-site, into an
existing public storm drain system within Starward Drive. Ultimately, storm water from the
project would be discharges into the unnamed Zone 7 facility north of the project site.
Prior to approval of a final subdivision map or issuance of building permits, the project applicant
will be required, by City regulation, to submit and have approved a drainage and hydrology study
which will include detailed calculations regarding the amount of storm water anticipated to be
generated and the ultimate disposition of the water. The project developer would also be required
to obtain necessary permits from Zone 7 to allow for additional discharge into the Zone 7
facility. With adherence to standard City procedures, no significant impacts are anticipated with
regard to absorption rates or increased storm water runoff and no mitigation measures are
required.
b) Exposure ofpeople orproperty toflood hazard? LS. The project site lies outside of the 100
year flood plain as identified on the applicable Flood Insurance Rate Map published by the
Federal Emergency Management Agency, Community Panel No. 060705 000 IA. This is not
considered a significant impact and no mitigation measures are needed.
c) Discharge into smface waters or changes to surface water quality? PS/M. The preliminary
grading concept for the project involves collecting on-site storm water mn-off and transporting it
to the west for ultimate ouffall into the unnamed Zone 7 flood control channel via a new ouffall
pipe. According to representatives from Zone 7, the Creek has been designed and constructed to
accommodate storm water flows which would be generated on the site under developed
conditions. Zone 7 will impose a number of standard conditions on the project builder to ensure
Zone 7 access to the channel for maintenance purposes and to ensure that the outfall pipe is
located and built to Zone 7 standards. The project developer will be required to obtain permits
from Zone 7 prior to any construction within the channel.

It is likely that initial storm water flows after a lengthy dry season (also known as "first flush"
flows) may add pollutants into the adjacent flood control channel, including but not limited to
grease, oil, fertilizers and other organic and inorganic material. Typically, subsequent flows
generally contain fewer amounts of pollutant material.
The City of Dublin is a co-permittee of the Alameda County Clean Water Program, which is a
coordinated effort by local governments in the County to improve water quality in San Francisco
Bay. In 1994, the San Francisco Bay Regional Water Quality Control Board issued a set of
recommendations for New and Redevelopment Controls for Storm Water Programs. These
recommendations include policies that define watershed protection goals, minimum non-point
source pollution controls for site planning and post construction activities. Watershed protection
goals are based on policies identified in the San Francisco Bay Basin Water Control Plan, which
relied on Best Management Practices (BMPs) to limit pollutant contact with stom~water runoff at
its source and remove such pollutants prior to being transported into receiving waters. The
following mitigation measure is therefore recommended to reduce surface water quality pollution
to a level of insignificance.
Mitigation Measure 4: The project developer shall prepare a Stormwater Pollution
Prevention Plan for approval by the Dublin Public Works and Planning Deparlments. The
Plan shall include specific BMP measures to reduce water quality impacts from
construction activities as well as from long term operational aspects of the proposed
subdivision.
d) Changes in amount of surface water? LS. Additional surface water will be added to the local
and regional flood control facility, however, with the imposition of Mitigation Measure 4 to
maintain water quality, this is not anticipated to be a significant impact. Representatives from
Zone 7 have indicated that the flood control system has been sized to accommodate storm water
run-off from this project. Therefore, less than significant impacts are anticipated to the amount of
surface water and no mitigation measures are needed.
e) Changes in currents or direction of water movement? NI. No significant changes to the
direction of surface water flow is anticipated and no mitigations are required.
f) Changes in quantity of groundwaters? NI. The project does not involve significant
underground construction and would therefore not affect groundwater resources. No mitigation
measures would therefore be required.
g) Altered direction of groundwater? NI. The project would have no impact to groundwater
resources and no mitigation measures are needed.
h) Impacts to groundwater quality? LS. The scope of the project does not include major
underground construction so that groundwater resources will not be significantly affected and no
mitigation measures are needed.
i) Substantial reduction of groundwater resources? LS. Future project residents will rely on
water supplied by the Dublin San Ramon Services District (DSRSD). According to
representatives of the District, the District anticipates adequate supplies to be able to provide a
long term water supply to the proposed project.

V. Air Quality
Environmental Setting
The project site is located within the Tri-Valley area, a sheltered, inland area surrounded by hills
to the west, south and east. Most of the air flow into the southern portions of the Valley is
accomplished through only two gaps in the hills: the Hayward and Niles canyons. Local wind
data show the frequent occurrence of low wind speed and calm conditiOns (the latter
approximately 23 percent of the time). These local limitations on the capacity for horizontal
dispersion of air pollutants combined with the regional characteristic of restricted vertical
dispersion give the area a high potential for regional air quality problems.
Project Impacts
a) Violation of air quality standard?. PS/M. Potential air quality impacts can be divided into
short-term, construction related impacts and long-term operational impacts associated with the
project.
In terms of construction-related impacts, it is anticipated that the project would generate
temporary increases in dust and particulate matter caused by site excavation and grading
activities. Construction vehicle equipment on unpaved surfaces also generates dust as would
wind blowing over exposed earth surfaces. Generalized estimates of construction air emissions
include approximately 1.2 tons of dust per acre per month of construction activity. About 45
percent of construction-related dust is composed of large particles which settle rapidly on nearby
surfaces and are easily filtered by human breathing patterns. The remainder of dust consists of
small particles (also known as PM10) and could constitute a more severe air quality impact,
unless mitigated.
The following mitigation measure is therefore recommended to reduce potential short-term,
construction related impacts.
Mitigation Measure 5: The following measures shall be incorporated into construction
specifications and shall be followed by the project grading contractor:
All material excavated or graded shall be sufficiently watered to prevent excessive
amounts of dust, Watering shall occur at least twice per day with complete coverage,
preferably in the late morning and at the completion of work for the day;
All clearing, grading, earthmoving and excavation shall cease during periods of high
winds greater than 20 mph over one hour;
All material transported off-site shall either be sufficiently watered or securely
fastened to prevent escape of dust and debris;
All inactive portions of the construction site shall be planted and watered, if
construction is accomplished in more than one phase;
On-site vehicle speed shall be limited to 15 mph;
During rough grading and construction, Starward Drive shall be swept at least once per
day, or as required by the City of Dublin, to remove silt and construction debris;
Unnecessary idling of construction equipment shall be avoided;
Equipment engines shall be maintained in proper working condition per manufacturers'
specification.

Construction of the proposed project will add additional vehicular traffic to this portion of
Dublin. These additional vehicles will generate quantities of carbon monoxide, reactive organic
gasses, nitrous oxide, sulfur dioxide and particulate matter (PM10). However, the location of the
proposed project near major transportation corridors (San Ramon Road and Amador Valley
Boulevard), the relatively high density of the project (approximately 14 units per acre) and the
fact that the proposed project is considered an "infill" type residential project results in
conformity with the Bay Area Air Quality Management District's Clean Air Plan.
b) Expose sensitive receptors to pollutants? LS. The project, if approved and constructed, would
add an anticipated 99 future residents to the project site. Since the site is located along San
Ramon Road, a major regional arterial highway, additional sensitive receptors, future residents,
would be exposed to somewhat higher concentrations of vehicle related pollutants. Given the
prevailing wind pattern, the amount of pollutant exposure is not anticipated to be significant and
no mitigation measures are required.
c) Alter air movement, moisture, temperature or climate? LS. The project is anticipated to
consist of two story residences, which will not significantly interfere with prevailing wind
patterns or climatic conditions. The final height of buildings within the project will be
determined through the Site Development Plan process. No mitigation measures are required.
d) Create objectionable odors? NI. As a proposed residential project, no objectionable odors are
to be created and no mitigation measures are required.
VI. Transportation/Circulation
Environmental Setting
Major regional access to the site is provided by Interstate 580, an east-west freeway, and .
Interstate 680, a north-south freeway. Primary access to the site on a city-wide level is provided
by Amador Valley Boulevard, an arterial roadway south of the site and San Ramon Road, a
major arterial roadway immediately west of the project site. Local access to the site is gained via
Starward Drive which forms the easterly site boundary.
Table 1, below, surmnarizes existing traffic conditions at key intersections near the proposed
project site. This information is based on information presented in the Downtown Dublin Traffic
Fee analysis, completed by TJKM Associates in 1996.
Existing conditions are expressed in terms of volume-to-capacity on adjacent roadways using the
Level of Service (LOS) concept. LOS ratings are qualitative descriptions of intersection
operations reported using an A through F ranking system to describe travel delay and congestion.
LOS A indicates free flow of n-affic through intersections and LOS F indicates jammed
conditions with excessive delay and long back-ups. The City of Dublin uses LOS D (volume-to-
capacity ratio of 0.90) as the minimum acceptable level of service in the community. Mitigation
measures must be imposed ff the addition of project traffic causes intersections operations to
drop to an LOS E or F.

Table 1 indicates that all three of the major intersections nearest the project site operate at
satisfactory levels of service under existing conditions.
The Downtown Traffic Fee Study analyzed furore traffic and transportation conditions assuming
full build out of the entire downtown area. As part of the analysis, future roadway improvements
have been assumed, including upgrading the 1-580/I-680 freeway interchange, the extension of
BART to east and west Dublin, and construction of a new high occupancy vehicle lane on 1-680
between 1-580 and Rudgear Road in Walnut Creek. Other assumed roadway improvements
include construction of the Shaefer Road interchange and construction of a new road paralleling
Dublin Boulevard between Amador Plaza Road and Golden Gate Drive.
Project Impact~
a) Increased vehicle trips or traffic congestion? PS/M. The proposed project would add
additional vehicles to local and regional roadways as a result of project construction.
Table 2, below, summarizes future (2010) traffic conditions in the Downtown Dublin area. The
analysis assumes future office development on the site. Assuming an average Floor Area Ratio of
0.30 for office development, a maximum of 31,300 square feet of office could be constructed on
the site under the downtown plan. Based on standard generation rates published in the Institute of
Traffic Engineers Trip Generation (Sixth Edition), an office development on the site would
generate 48 morning peak hour trips and 46 evening peak hour trips. By comparison, the
proposed project would generate 31 morning peak hour trips and 37 evening peak hour trips.
Therefore, the following future traffic conditions analysis can be considered a conservative
estimation of potential traffic impacts.

unsignalized (stop-controlled) intersection.
Based on the above analysis, construction of the full build out of the Downtown Specific Plan
would not result in significant traffic impacts at major intersections near the project site during
peak morning or evening hours.
The following mitigation measure is recommended to ensure that any future cumulative impacts
of the project would be mitigated and to ensure consistency with adopted City requirements:
Mitigation Measure 6: The project developer shall pay a Traffic Impact Fee (TIF) for
this project prior to or concurrently with the issuance of building permits.
b) Hazards to safety from design features (e.g. sharp curves or dangerous intersections) or
incompatible uses (e.g. farm equipmenO? PS/M. Although a final, precise design for the
proposed project has not been submitted by the applicant, implementation of the following
mitigation measure will ensure that all no public safety hazards will be created.
Mitigation Measure 7: The f'mal design of the project shall meet all Dublin Public
Works Department, Police Department and Fire Department policies and standards for
internal street widths and comer radii.
c) Inadequate emergency access or access to nearby uses? LS. The applicant proposes two drive
approaches from Starward Drive. This complies with Dublin Police Department and Alameda
County Fire Department requirements of providing two access points for a residential project of
this size. No impacts are therefore anticipated with regard to emergency access and no mitigation
measures are required.
d) Insufficient parking capacity onsite or offsite? LS. The proposed project would supply parking
at a ratio of 2.0 spaces per unit within an enclosed garage per unit plus a additional open parking
on a number of driveways. The site plan also indicates that 15 onsite guest parking spaces would
be dispersed throughout the project site. This quantity of parking meets City parking
requirements so that no impacts would be created and no mitigations are required.

July 1998
e) Hazards or barriers for pedestrians or bicyclists? LS. The proposed project would not result
in barriers or hazards to pedestrians or bicyclists. A sidewalk currently exists along the west side
of Starward Drive along the frontage of the site. Although internal sidewalks are not proposed,
the limited volume of internal traffic is not anticipated to be heavy so that pedestrians and
bicyclists may use the internal roadway for non-vehicular circulation. No significant impacts are
anticipated and no mitigation measures are required.
f) Conflicts with adopted policies supporting alternative transportation (e.g. bus turnouts,
bicycle racks)? LS. Construction of the proposed project would serve to advance regional and
subregional goals and policies which promote the development of higher density residential
projects near major transportation corridors. No significant impacts are anticipated and no
mitigation measures are needed.
g) Rail, waterborne or air traffic impacts? NI. The proposed project is not sited near operating
raikoad facilities, near a navigable waterway or near an airport so that no impacts would result
should the project be built. No mitigations are required.
VII. Biological Resources
Environmental Setting
The site is currently vacant and is generally devoid of vegetation. The one exception is a column
of mature trees growing along the southerly and westerly property boundaries. Single trees are
also found along the northerly property line. The only significant tree on or adjacent to the site
includes a 48" walnut tree generally located on the southwest comer of the site, but located
mediately off the project site.
Project Impacts
a) Endangered, threatened or rare species or their habitats (including but not limited to plants,
fish, insects, animals and birds) NI. No such species have been observed on the site based on
filed observations conducted in January, 1998. No impacts are anticipated and no mitigation..-
measures are therefore required.
b) Locally designated species (e.g. heritage trees). PS/M. Development plans submitted by the
applicant indicate that the majority of trees on the perimeter of the site would be removed. The
48" walnut southwest of the site would be retained. The following mitigation measure is
recommended to ensure that the walnut tree is safely preserved:
Mitigation Measure 8: Prior to issuance of grading permits, the project developer shall
prepare a tree preservation plan for the off-site walnut tree, including limitations on
grading near the drip line of the tree, providing temporary fencing of the tree during
construction and clean cutting of tree roots, if necessary. The tree preservation plan shall
be approved by the City's landscape architect.
c) Locally designated natural communities (e.g. oak forest, coastal habitat) NI. There are no
significant stands of vegetation on the site so that no impacts would result to natural biotic
conditions and no mitigations are required.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 35
July 1998
d) Wetland habitat (e.g. marsh, riparian and vernalpool)? LS. No wetlands exist on the project
site so that no impacts would result if the project were built and no mitigation measures are
required.
e) Wildlife dispersal or migration corridors? NI. The site is substantially surrounded by existing
commercial and residential development and no wildlife corridors have been observed on the
site. The flood control facility north of the site could serve as a wildlife corridor area, however,
the facility has' been fenced to preclude access by the general public. Therefore, significant
impacts are not anticipated and no mitigation measures are required.
VH. Energy and Mineral Resources
Environmental Setting
The Conservation Element of the Dublin General Plan does not reference any significant mineral
resources on the project site nor were any such resources observed during a field investigation in
June, 1998.
Project Impacts
a) Conflict with adopted energy conservation plans? NI. The proposed project will not conflict
with energy goals, policies or programs established in the General Plan regarding energy or
energy conservation. No mitigation measures are required.
b) Use nonrenewable resources in a wasteful and inefficient manner? NI. The proposed project
is not anticipated to use resources in a wasteful manner. The project will be constructed in accord
with the Uniform Building Code and Tire 24 of the California Administrative Code, both of
which require stringent energy efficient construction methods, such as insulation, thermal pane
windows and installation of efficient appliances. Exterior landscaping will be governed by both
AB 325 and Section 8.88 of the Dublin Zoning Ordinance, which requires "water budgets" for.
landscape material sand methods of irrigation. Finally, the City is mandated by AB 939 to reduce
the solid waste stream generated by residences, business and industrial establishments by
promoting recycling and similar programs. No specific mitigations measures are required.
c) Result in the loss of availability of a known mineral resource that would be of future value to
the region and residents of the State? NI. The preliminary geotechnical investigation for the
project did not indicate that significant quantities of mineral resources are located on the site.
IX. Hazards
Environmental Setting
A Phase I Environmental Assessment was completed for the project site in May, 1997 by the
f'u'm of ACC Environmental Consultants. The purpose of the assessment was to identify
historical or current sources of contamination or hazards on the site. The report concludes that no
evidence of recognized environmental conditions exist on the site. Within one-half mile of the
site, a number of documented releases of hazardous substances and/or petroleum products exist,
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 36
July 1998
however, there is no documented evidence that constituent plumes originating from any of these
sites have migrated to or under the project site.
Project Impacts
a) A risk of accidental explosion or release of hazardous substances including but not limited to
oil, pesticides, chemicals, or radiation? LS. The proposed residential project will not contain
substantial quantities of oil, pesticides, chemicals or radiation. It is likely that limited quantities
of household chemicals, pesticides, herbicides and similar materials would be used and stored on
the site, either in individual units or for maintenance purposes. The amounts of such materials
would be typiCal of any residential development in the community and such quantities are not
considered to be significant. No mitigation measures are required.
b) Possible interference with an emergency response plan or emergency evacuation plan? LS.
The proposed project would not block Starward Drive, San Ramon Road or any other major
evacuation routes so that no impacts would result should the project be built.
c) The creation of any health hazard or potential health hazards? NI. As a proposed residential
development, the project will not generate a health hazard and n mitigation measures are
required.
d) Exposure of people to existing sources of potential health hazards? NI. Based on the
completed Phase One Analysis, no documented sources of health hazard exists on the site. No
mitigation measures are required.
e) Increased fire hazard in areas with flammable brush, grass or trees? PS/M. Construction of
the proposed project will add wood frame dwellings, garages and other related improvements,
including new landscaping. All structures will be built in conformity with provisions of the
Uniform Building Code and Uniform Fire Code to minimize fire hazard. Landscaped areas will
be permanently irrigated to ensure that plant material will not be flammable, based on
recommended Mitigation Measure 9, below.
Mitigation Measure 9: Permanent irrigation systems and automatic controllers shall be
installed within all front yard areas and along the Starward Drive project frontage to assist
in reducing the danger from grass gu:es.
X. Noise
Environmental Setting
Primary long term sources of noise in the vicinity of the project site include vehicular-related
noise emanating from San Ramon Road and a combination of vehicular and operational noise
from the existing Shamrock commercial center south of the project site. A noise barrier masonry
wall has been constructed along the west side of San Ramon Road north of the project site, but
this wall does not extend along the project frontage. There is currently no noise barrier between
the project site and the commercial center south of the site. Although a specific noise analysis
has not been performed for this project, it is estimated that existing noise levels exceed the
maximum City exterior noise exposure level of 65 dBA for single family neighborhoods. The
City and state maximum interior noise exposure level is 45 dBA.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 37
July 1998
Project Impacts
a) Increases in existing noise levels? PS/M. As a residential project, small, incremental
permanent increases in noise from automobiles, mechanical and gardening equipment and similar
sources can be expected. These are not anticipated to be significant. Short-term construction
related noise can also be expected to be generated which could be considered significant based
on specific types of equipment which may be used in the construction process. Noise impacts
would be felt by residences of existing residential dwellings north of the project site.
The following mitigation measure is therefore recommended to limit the potential impacts of
construction noise on adjoining properties to an acceptable level.
Mitigation Measure 10: All construction activities on the project site shall be limited to
7 a.m. to 5 p.m., Monday through Friday, unless alternative hours are approved by the
Dublin Building Official for structural construction and the City Engineer for grading
activities. Construction equipment, including compressors, generators, and mobile
equipment, shall be fitted with heavy duty mufflers designed to reduce noise impacts.
b) Exposure of people to severe noise levels? PS/M. Construction of the proposed project would
expose residents of dwellings on the southerly and westerly portion of the site to noise levels in
excess of that established in the Dublin General Plan. The proposed development plan indicates
that a solid noise barrier wall would be constructed along the north, west and south property
lines, although precise locations have not been submitted. The following mitigation measure is
recommended to reduce off-site noise impacts on the project to a level of less than significance.
Mitigation Measure 11: The project developer shall have a qualified acoustical
consultant:
(1) Verify and approve the precise location, heights and type of materials to be
used for noise barrier walls. Noise barrier wall plans submitted to the City
for building permits shall be stamped approved by the acoustical
consultant.
(2) Verity that interior noise levels for dwellings constructed on lots 1-16
comply with maximum interior noise levels established by the City of
Dublin and California Administrative Code. Construction plans shall be
stamped approved by the qualified acoustical consultant.
XI. Public Services.
Environmental Setting
The project site is served by the following service providers:
Fire PrOtection, Fire protection is provided by the Alameda County Fire Depaxtrnent,
under contract to the City of Dublin, which provides structural fire suppression, rescue,
hazardous materials control and public education services. The closest Fire Station is
located on Donohue Drive approximately one-quarter mile east of the project site.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 38
July 1998
Police Protection. Police protection is provided by the Dublin Police Department which is
headquartered in the Civic Center. The Department, which maintains a sworn staff of 31
officers, performs a range of public safety services including patrol, investigation, traffic
safety and public education.
Schools. Educational facilities are provided by the Dublin Unified School District which
operates kindergarten through high school services within the community. Schools which
would serve the project include Dublin High School (grades 9-12) and Wells Middle
School (graded 6-8). Grades K-5 could be served by one of three elementary schools
within the District.
Maintenance. The City of Dublin provides public facility maintenance, including roads,
parks, street trees and other public facilities. Dublin's Civic Center is located at 100 Civic
Plaza.
Other governmental services. Other governmental services are provided by the City of
Dublin including community development and building services and related
governmental services. Library service is provided by the Alameda County Library with
supplemental funding by the City of Dublin.
The City of Dublin has adopted a Public Facilities Fee for all new residential development in the
community for the purpose of financing new municipal public facilities needed by such
development. Facilities anticipated to be funded by the proposed fee would include completion
of the Civic Center Complex, construction of a new library, expansion of the existing senior
center, acquisition and development of new community and neighborhood parks and similar
municipal buildings and facilities. The applicant would be required to pay this fee.
Project Impacts
a) Fire protection? PS/M. According to representatives of the Fire Department, the proposed
project lies within a quarter mile radius of a fire station located on Donohue Drive north of
Amador Valley Boulevard. A typical response time of under five minutes is anticipated. As'part
of the site development review process, specific fire protection requirements will be imposed on
the development to ensure compliance with applicable provisions of the Uniform Fire Code.
This would include installation of f'n'e hydrants and similar fhe protection measures. A
potentially significant impact would be the width of the proposed private street through the site,
which is planned to be 24-feet. with no on-street parking allowed. Although considered adequate
to accommodate normal vehicular traffic through the site, any vehicles parking on the street
could block access by fire and/or police emergency vehicles and could possibly hinder
emergency evacuation of the site. The following mitigation measure is recommended to reduce
this potential impact to a level of insignificance:
Mitigation Measure 12: The private street through the site shall be painted and striped to
preclude vehicle parking adjacent to the curb. Signing and painting shall be approved by
the Alameda County Fire Department and Dublin Police Department prior to occupancy
of any portion of the project. In addition, the project developer shall provide written
authorization for Police and Fire officials to enforce the no parking requirement.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 39
July 1998
b) Police protection? PS/M. The Police Department has indicated an ability to provide safety and
security services to the proposed project. Adherence to Mitigation Measure 11 will ensure that
adequate emergency access would be provided through the site at all times.
c) Schools? PS/M. The Dublin Unified School Disu'ict recently completed a Facilities Master
Plan which includes estimates of student generation by residential density type. Since many local
schools are or are expected to be at full capacity in the near future, the following mitigation is
recommended to ensure that potential impacts can be reduced to a less than significant level.
Mitigation Measure 13: The applicant shall, prior to issuance of building permits, obtain
a written agreement with the Dublin Unified School District for the project's fair share
mitigation of school impacts. Any fees which are required pursuant to that agreement
shall be paid prior to issuance of building permits.
d) Maintenance of public facilities, including roads? LS. The project represents an incremental
increase in area population and vehicles. Roadways within the project will be privately owned
and maintained. The applicant is required to pay a traffic impact fee to the City of Dublin which
will assist in off-setting costs of public roadway maintenance. In regard to the existing slope
easement adjacent to San Ramon Road, the proposed grading plan calls for a retaining wall in the
general vicinity of the existing slope easement so that the slope easement would no longer be
needed and can safely be abandoned.
e) Other gouernmental services? LS. The project would represent incremental increases in the
demand for general governmental services. Payment of the City's Public Facility Fee would
offset any impacts caused by the project.
XII. Utilities and Service Systems.
Environmental Setting
The project site is served by the following service providers:
· Electrical and natural gas power: Pacific Gas and Electric Co.
· Communications: Pacific Bell
° Water supply and sewage treatment: Dublin San Ramon Services District
· Storm drainage: City of Dublin
° Solid waste disposal: Dublin-Livermore Disposal Company
Project Impacts
a) Power or natural gas? LS. According to representatives from Pacific Gas and Electric
Company, adequate facilities exist in the vicinity of the project to provide power and natural gas
service. No impacts to electrical power or natural gas systems are anticipated and no mitigation
measures are needed.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 40
July 1998
b) Communication systems? LS. According to representatives from Pacific Bell, communication
facilities presently exist near the site which could be extended to serve future development on the
site. No impacts are anticipated and no mitigation measures are required.
c) Local or regional water treatment or distribution systems? LS. According to representatives of
DSRSD, existing underground water facilities exist in nearby streets to supply adequate
quantifies and pressure to meet minimum domestic and fire flows. Less than significant impacts
are anticipated to local and regional water treatment facilities and no mitgafion measures are
required. Reference Section IV, Water, for a discussion of long term water supplies to the
project.
d) Sewer or septic systems? LS. According to representatives of DSRSD, a sewer line has been
constructed within Starward Drive which would adequately accommodate anticipated wastewater
requirements of the project. Adequate capacity exists to accommodate anticipated sewer flows
from the proposed project. Untreated effluent would be transported to DSRSD's Regional
Treatment Plant in Pleasanton for treatment prior to being discharged into the East Bay
Discharge Authority's ouffall line for eventual disposal into San Francisco Bay. DSRSD officials
indicate that adequate capacity exists within the regional treatment facility to accommodate this
project.
e) Storm water drainage? LS. This topic was previously addressed in Section IV, Water.
f) Solid waste disposal? LS. The City of Dublin contracts with Livermore-Dublin Disposal
Company to collect solid waste from households and businesses and transport it to the Altamont
Landfill, located in eastern Alameda County. The Landfill currently has an anticipated capacity
until the year 2005 and plans are underway to extend landfill capacity for an additional 50 years.
Livermore-Dublin Disposal Company also operates a curbside recycling service to ensure that
the City's waste stream complies with state requirements for reduction of solid waste, The most
current information available indicates that Dublin exceeds state requirements for reducing solid
waste.
Although approval of the proposed project will incrementally increase the amount of solid waste,
any such increases will be able to be accommodated with existing facilities and resources.
g) Local or regional water supplies? LS. DSRSD staff indicate that adequate long term water
supplies are available from Zone 7 and other sources to serve the proposed project. No mitigation
measures are needed.
XIII. Aesthetics.
Environmental Setting
The site is currently vacant of any permanent structures. The onlY feature of aesthetic
significance in the immediate vicinity is the large walnut tree southwest of the site.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 41
July 1998
Project Impacts
a) Affect a scenic vista or view? NI. Based on a field observation of the project site, no existing
views or vistas would be blocked to a significant degree and no mitigation measures are required.
b) Have a demonstrable negan've aesthetic effect? PS/M. The proposed project would be largely
self contained with adequate landscaped buffering or noise barrier walls on all sides. However,
the design and appearance of the noise wall is unknown at this time. If not properly designed, the
noise barrier wall could result in a significant adverse impact for motorists passing the site on
San Ramon Road as well as from adjoining properties. The following mitigation measure is
therefore recommended to reduce potential aesthetic impacts to a level of insignificance:
Mitigation Measure 14: Perimeter noise barrier walls shall be attractively designed of
masonry block or alternative materials with the fmal design to be approved as part of Site
Development Plan review to ensure that the barrier wall will not result in a negative
aesthetic impact. The perimeter wall shall also be painted with graffiti-resistant paint.
c) Create light or glare? LS. The proposed residential project would add additional exterior
lighting in the project vicinity, including driveway lighting, security fighting and porch lights and
other light sources. However, perimeter walls would be constructed to block spill over of light
onto adjacent sites so that no significant impacts would result and no mitigation measures would
be required.
XIV. Cultural Resources
Environmental Setting
There is evidence that the site contains a streambed that has been filled many years ago.
Generally, historic and prehistoric habitation occurred on sites adjacent to creeks, streams and
other bodies of water, although no surface evidence exists that such artifacts are present on this
site.
Project Impacts
a) Disturb paleontological resources? PS/M. Construction of the proposed project could disturb
buried paleontological artifacts through grading and general site construction. This would be a
potentially significant impact. Adherence to the following mitigation measure would reduce this
impact to a level of less than significant:
Mitigation Measure 15: Should archeological artifacts or remains be discovered during
construction of the project, Work in the vicinity of the find shall stop immediately until a
qualified archeologist can evaluate the site and determine the significance of the fred.
Project personnel shall not collect or alter cultural resources. Identified cultural resources
shall be recorded on forms DPR 422 (archeological sites) and/or DPR 523 (historic
resources). If human remains are found, the County Coroner shall be contacted
immediately.
b) Disturb archeological resources? PS/M. Adherence to Mitigation Measure 14 would also
reduce potential impacts to archeological resources to a level of less than significance.
Dublin Planning Department
Starward Drive Project/Initial Study
PA 98-013
Page 42
July 1998
c) Have the potential to cause a physical change which would affect unique ethnic cultural
values? NI. The site is presently vacant and exhibits no unique ethnic or cultural values. No
impacts are therefore anticipated and no mitigation measures are required.
d) Restrict existing religious or sacred uses within potential impact area? NI. Similar to above,
the site does not contain unique religious or sacred uses so that no mitigation measures are
needed.
XV. R~creation.
Project Impacts
a) Increase the demand for neighborhood or regional parks or other recreational facilities? LS.
The addition of approximately 99 residents in this portion of the City will add an incremental
demand for parks and recreational facilities. This would be a significant impact and the following
mitigation measure is recommended to reduce potential recreational impacts to a level of less
than significance:
Mitigation Measure 16: The project developer shall pay required Quimby Act park in-
lieu fees to the City of Dublin prior to issuance of building permits.
b) Affect existing recreational opportunities? NI. The project site does not contain existing
recreational facilities and no impacts are anticipated.
XVI. Mandatory Findings of Significance
a) Does the project have the potential to degrade the quality of the environment, substantially
reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below
self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number of
or restrict the range of a rare or endangered plant or animal or eliminate important examples of
the major periods of California history or prehistory? No. The preceding analysis indicates that
the proposed project will not have a significant adverse impact on overall environmental quality,
including biological resources or cultural resources.
b) Does the project have the potential to achieve short-term, to the disadvantage of long-term,
environmental goals'? No. The project represents an example of infill, higher density housing
which will be sited near a major regional transportation corridor.
c) Does the project have impacts that are individually limited, but cumulatively considerable?
("Cumulatively considerable" means that the incremental effects of a project are considerable
when viewed in connection with the effects of past projects, the effects of other current projects
and the effects of probable future projects). No although incremental increases in certain areas
can be expected as a result of constructing this project, including additional traffic, air emissions,
and need for public services and utilities, the project site lies within an already urbanized area
and sufficient capacity exists within service systems to support the additional population
anticipated associated with the project.

July 1998
d) Does the project have environmental effects which will cause substantial adverse effects on
human beings, either directly or indirectly? No. Although potential safety impacts exist in the
vicinity of the site, adequate mitigations are proposed to reduce such potential impacts to levels
of insignificance.
