DETERMINATION: (To be completed by the Lead Agency)
On the basis of this initial evaluation:
find that the proposed project COULD NOT have a significant effect on the environment, and a
N'EGATIVE DECLARATION will be prepared.
~ I find that although the proposed proj e~ could have a significant effect on the environment, there
will not be a significant effect in this case because revisions in the project have been made by or agreed to
by the project proponent. A I~TIGATED hrEGATIVE DECLARATION will be prepared.
find that the proposed project IvL4~Y have a si_m'fificant effect on the environment, and an
EN'V!RO!N~_IENTAL IiVIPACT REPORT is required.
F"[ I find that the proposed project NLA~Y have a "potentially sig-nificant impact" or "potentially
significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately
2
analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed ~
mitigation measures based on the earlier analysis as described on attached sheets. An
ENWIRONMENTAL IM2PACT REPORT is required, but it must analyze only the effects that remain
to be addressed.
O I find that although the proposed project could have a significant effect on the environment,
because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or
h~EGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or
mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or
mitigation measures that are ' }¢9osed upon the proposed project, nothing further is required.

Printed name
EV,M_,UATION OF ENVIRO~NTAL/MPACTS:
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 parentheses 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 standards (e.g., the project will not expose sensitive receptors to pollutants,
based on a project-specific screening analysis).
2)
,~dI answers must take account of the whole action involved, 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)
Once the lead agency has determined that a particular physical impact may occur, then the checklist
answers must indicate whether the impact is potentially significant, less than significant with
mitigation, or less than sig~h3cant. "Potentially Si=omificant impact" is appropriate ff there is
substantial evidence that an effect may be sigr~ificant. If there are one or more "Potentially
Significant Impact" entries when the determination is made, an EIR is required.
4)
"Negative Declaration: Less Than Sigrificant With Mitigation incorporated" applies where the
incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to
"Less Than Significant Impact." The lead agency must describe the mitigation measures, and briefly
5)
6)
7)
explain how they reduce the effect to a less than significant level (mitigation measures from Section
XVII, "Earlier Analyses," may be cross-referenced).
Earlier analyses may be used where, pursuant to the tiering, program EI2P,, or other CEQA process,
an effect has been adequately analyzed i'n an earlier EIX or negative declaration. Section
15063(c)(3)CD). In this case, a brief discussion should identify the following:
a) Earlier Analysis Used. Identify and state where they are available for review.
b)
impacts Adequately Addressed. Identify which effects from the above checklist were
within the scope of and adequately analyzed in an earlier document pursuant to applicable
legal standards, and state whether such effects were addressed by mitigation measures
based on the earlier analysis.
c)
Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures
Incorporated," describe the mitigation measures which were incorporated or refined from
the earlier document and the extent to which they address site-specific conditions for the
project.
Lead agencies are encouraged to incorporate into the checklist references to information sources for
potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or
outside document should, where appropriate, include a reference to the page or pages where the
statement is substantiated.
Supporting Information Sources: A source list should be attached, and other sources used or
individuals contacted should be cited in the discussion.
This is. only a suggested form, and lead agencies are free to use different formats; however, lead
agencies should normally address the questions from this checklist that are relevant to project's
environmental effects in whatever format is selected.
The explanation of each issue should identify:
a) The significance criteria or threshold, if any, used to evaluate each question; and
b) The mitigation measure identified, if any, to reduce the impact to less than sig~ficance.

Project Description - Dublin Boulevard widening from Dougherty Road to Scarlett Drive
This project is necessitated by new traffic generated in Eastern Dublin from new development.
The northerly portion of this roadway segment was previously constructed to its ultimate width
and is now striped for one lane in each direction. The proposed new improvement will complete
the roadway to its ultimate width of six lanes divided by a landscaped median. It is anticipated
that eminent domain may be initiated for acquisition of some of the properties necessary for
construction.
Designs for this Capital Improvement Project (CIP No. 96890) show a six-lane roadway
including a landscaped and lighted center median, curb and gutter, and a sidewalk along the
south side, with total roadway widths of between 110 and 118 feet. Engineering Department staff
anticipate that the Dublin Boulevard/Dougherty Road intersection will be restriped and signal
phasing may be modified as a result of the proposed project. This project is proposed to be
completed in one phase, starting in Spring 2000, with completion anticipated for September,
2000. A proposed signal for the intersection of Dublin Boulevard and Scarlett Drive is also
included in this project.
It should be noted that this project has been designed to accommodate the future extension of
Iron Horse Trail where it crosses Dublin Boulevard, near the intersection with Scarleft Drive.
The area of the future right-of-way includes portions of three parcels that are currently not
owned by the City of Dublin or for which the City has not obtained easements over said
properr3,'. The City currently anticipates that for certain properties involved, eminent domain
(defined as the right of the government [City of Dublin] to take private property for public use by
virtue of superior dominion of the government over all lands within its jurisdiction) may be
inkiated.
Su_rrounding Land Uses and Sbtting
Dublin Boulevard, east of Dougherty Road, is currently a two-lane roadway (the result of a
previous phase of this project, which improved the north side of Dublin Boulevard and has both
~avel lanes located on this side), approximately 39 feet in width. Properties on the north and
south sides of this portion of Dublin Boulevard include a mixture of commercial, retail, light
industrial and hotel uses.
Exhibk 1 indicates the Project Vicinity for the proposed project.
Dublin Boulevard Widening - CIP 96890 Page 18
Explanations
The following section provides narrative responses that correspond with the environmental
checklist form.
I. Aesthetics
a-c - Dublin Boulevard is a major east-west thoroughfare through the City. Views of the
surrounding foothills in the distance are visible while travelling along the roadway, with more
rural features as one travels easterly. However, this portion of Dublin Boulevard is not
designated by the City as a scenic route, nor are there any identified scenic resources in the
immediate vicinity. t~idening of Dublin Boulevard from Dougherty Road easterly t.o Scarlett
Drive is anticipated to have no impacts on scenic vistas and scenic resources, and a Jess than
significant impact on the visual quality of the site/surroundings. Aro mitigation is required.
Extensive landscaping, in the form of 24-inch and 36-inch box-sized street trees, perennial
shrubs, groundcovers, special concrete paving and pilaster and lattice features are proposed in
the center median and along the south side of Dublin Boulevard. This is in addition to existing
street trees located on the north side of Dublin Boulevard. These are beneficial aspects of the
proposed project and will serve to improve the aesthetics of the project area.
d - New street lights are proposed as part of the landscaping improvements included with the
proposed project. Lighting shall be installed per City standards. Given the existing developed
urban environment, impacts are anticipated to be less than significant.
II. Agriculture Resources
~-c - The proposed project does not encompass nor would it affect any properties currently in
a~icultm-al production. Azo impacts are anticipated
III. Air QuaiiB,
a-e - This project is being constructed in response to anticipated build-out conditions for East
Dublin, in order to accommodate existing and future vehicle traffic. Therefore, it can be assumed
that any increase in traffic-related air quality has been accounted for and/or has been mitigated
through fie approval process for the Easter Dublin Specific Plan. This project would not be in
violation of any applicable air quality standards. Substantial pollutant concentrations are not
anticipated with the roadway widening. Upon completion of construction, no objectionable odors
would be created. No impacts are anticipated
It should be noted, however, that due to the anticipated earthwork involved for this roadway
widening project, short-term increases in particulate matter ~Mm0) concentrations can be
expected in the project vicinity during the grading operations. This could impact existing
businesses and uses on either side of Dublin Boulevard
Dublin Boulevard Wid:ning - CIP 96890 Page 20
The following mitigation measures are recomme~led in order to mitigate potential construction-
related air quality impacts to a level of insignificance.
Twice-daily watering of exposed earth surfaces shall occur throughout the
construction phase. In addition, daily watering and/or sweeping of affected street
surfaces shall take place. This shall be accomplished to the satisfaction of the
Public Works Director.
.IV. Biological Resources
a-f- One existing street tree which is located in the median, is proposed for removal to
accommodate the proposed pilaster and lattice structures. Given the developed nature of the
project vicinity, the extensive street tree plantings proposed, and the fact that no biologically
sensitive resources are located near or would be affected by proposed construction, no impacts
are anticipated
V. Cultural Resources
a-b -No known cultural, paleontological, or historical resources exist within the proposed
project area. Therefore, no impacts to known resources are anticipated
c-d - The soil re-engineering required for the project will expose the substrate during _.m-ading
activities. Should previously unk, nown culturdl resources be discovered, the following mitigation
measure is recommended in order to mitigate potential impacts to a level of insignificance.
V-1.
In the event that archaeological resources, prehistoric or historic artifacts are
discovered during any construction or excavation, the following procedures shall
be followed:
· Construction and/or excavation activities shall cease immediately and the
,Department of Community Development shall be notified.
A qualified archaeologist shall be consulted to determine whether any such-
materials are significant prior to resuming ground breaking construction
activities. Standardized 'procedures for evaluating accidental finds and
discovery of human remains shall be followed as prescribed in Sections
15064.5 and 15126.4 of the California Environmental Quality Act.
Xq. Geolo_~v and Soils
a-e- Engineering Department staff have indicated that previous geotechnicaI studies performed
during the widening of the northern portion of Dublin Boulevard, indicate that on-site soils are
suitable for the proposed street improvements. Staff has indicated that a small amount of fill will
be required, with cut and fill for the project to be balanced on-site. The project area is not located
within a 'known earthquake fault zone, and on-site soils are not susceptible to seismic-related
Dublin Boul~-vard Widening - CIP 96890 Page 21
ground failure. No mapped landslides exist in the project area. Due to the project site's relatively
flat topography, substantial soil erosion during the construction phase is not anticipated. On-site
soils are not known to be unstable or expansive. The project does not involve the use of septic
tanks. Impacts are anticipated to be less than significant or non-existent.
VII. Hazards and Hazardous Materials
a, c-h - The proposed project includes widening of an existing roadway. The project does not
involve the storage or use of hazardous materials. No impacts are anticipated
b - Soil sampling and chemical testing of potentially contaminated soils prior to widening of the
northern half of Dublin Boulevard resulted in positive detection of oil and grease. The area in
question was in the vicinity of a small underground tank that was discovered during excavation.
The tank appeared to have been used as a hydraulic fluid reservoir. The tank was subsequently
removed and soil contamination remediated.
Existing land uses for the properties located on the south side of Dublin Boulevard that are to be
acquired by the City for this project, include a lumberyard, light manufacturing, and recreation
vehicle sen, ice center. To date, no site assessment has been performed on these properties. It is
not known whether these .existing uses have resulted in potentially hazardous conditions, which
could range from soil-staining to unauthorized dumping. This is considered a potentially
significant impact.
The following mitigation measures are recommended in order to mitigate potential hazardous
materials impacts to a level of insignificance.
VII-1. Prior to construction of project, a Phase I Environmental Assessment shall be
prepared by a qualified professional, which covers the three properties to be acquired by
the Ci~~. Any recommendations made in the report shall become conditions of project
approval. Any required remediation shall be satisfactorily accomplished prior to issuance
of ~ading permits. This shall be accomplished to the satisfaction of the Public Works
Director.
VIII. Hydrology and Water Quality
a, f-j - The proposed project includes widening of an existing roadw'ay and would not affect
water quality standards. This portion of Dublin Boulevard is not located within the 100-year
floodplain and proposed modifications would not expose people or structures to flooding. No
imt~acts are anticipated
b - e - Proposed roadway modifications include slightly raising the City's storm drain pipe in
order to accommodate the Dublin-San Ramon Service District's existing Clean Water Revival
(CWP,.) pipe. Although widerig of the roadway represents an increase in impervious stuffaces in
the immediate project vicinity, the project has been designed so as not to impact the existing
drainage system. The project site is less than five acres in size, therefore NPDES/S~.rPPP
permitting is not required. impacts are anticipated to be less than significant.
Dublin Boulevard Widening - CIP 96890 Page 22
IX. Land Use and Planning
a-c - This proposed Capital Improvement Program (CIP) project is in response to planned and'~
approved developments located in Eastern Dublin. The City's Circulation Element shows this
section of Dublin Boulevard ultimately developed as a six-lane major street, which is in keeping
with the proposed project. In addition, the Circulation Element shows a proposed Class II bike
route along Dublin Boulevard. A Class II bike lane is defined as having a striped lane for one-
way bike travel on the street. Although the proposed project is not providing a striped bike lane,
the automobile travel lanes have been reduced in width in order to provide the minimum four
foo~ bike lane width. (Please also refer to discussion under Transportation/Traffic). The project
area is not included in any habitat conservation plans or natural community conservation plans.
Assuming implementation of mitigation measure XV-1, land use and planning impacts are
considered to be less than significant. No further mitigation is required.
X. Mineral ResourCes
a-b - The project site is currently developed and is not located in an area identified in the
General Plan as a mineral resource area..No impacts are anticipated
XI. Noise
~a - c, e, f- The proposed project is in response to planned and approved development located in
Eastern Dublin. Therefore, it can be assumed that any increase in traffic-related noise has been
accounted for and/or has been mitigated through the approval process for the Eastern Dublin
Specific Plan and this project would not be in violation of any applicable noise standards. Noise
impacts are anticipated to be less than significant.
d - The proposed project includes gradthe, and roadway construction. Lo~al businesses will be
subjected to short-term localized increases in ambient noise. levels during the construction phase.
The following mitigation measures are recommended in order to reduce potential short~term
noise impacts to a level of insignificance.
In order to minimize the impact of construction noise, all operations shall comply
with local noise standards relatir~g to construction activities. Construction hours
shall be limited to those hours'as established by the City. StationaU equipment
shall be adequately muffled and located as far away from sensitive receptors as
possible.
.'~I. Ponuladon and Housing
- The proposed project includes widening and other modifications to an eftsting roadway.
population and housing impacts are anticipated
Dublin Boulevard Widening - CIP 96890 Page 23
XIII. Public Services
a -The proposed project includes widening and other modifications to an existing roadway. 2Vo
impacts to fire protection, police protection, schools, or parks are anticipated Due to the fact
that the proposed project is a CIP Foject, any future required maintenance will be accounted
for in the City's yearly budget. ]~oadway maintenance impacts are anticipated to be less than
significant.
XIV. Recreation
a - The proposed extension of the Iron Horse Trail is anticipated to be constructed in the year
2000. The trail is located within the former Southern Pacific Railroad fight-of-way, and is
oriented in a northwest to southeast direction. The Iron Horse Trail is a regional trail that
currently extends from Concord to Dublin. This proposed link, which is presently in the
planning stage with the Alameda County Public Works Department, would cross Dublin
Boulevard just east of the Scarlett Drive intersection and would provide visitors direct access to
the trail from the DublinfPleasanton BART station. The proposed Dublin Boulevard widening
project may impact this trail connection. This is considered a ?otentially signz.'~cant impact.
~e following mitigation measures are recommended in order to reduce potential recreation
impacts to a level of insignificance.
XIV-I. The City of Dublin shall continue to coordinate with the Alameda Count), Public
Works Department for accommodation of the extension of Iron Horse Trail across Dublin
Boulevard. Dependent upon the timing for construction of the two projects, this may
include temporary measures such as installation of a portable bridge, as well as
p~rmanent design modifications necessary to meet requirements for the trail.
b - The proposed project includes widening and other modifications to an existing roadway. No
impacts to recreation facilities are anticipated.
XV. Transportation/Traffic
a-g - The proposed pro_}ect includes the widening of Dublin Boulevard between Dougherr3, Road
and Scarlett Drive from two lanes (one lane in each direction) to six lanes (three lanes in each
direction). This additional roadway capacity is needed to accommodate future average daily
~affic (ADT) volumes, which is expected to exceed 40,000 vehicles per day (vpd) with the
buildout of East Dublin. Based on methodology presented in the Transportation Research
Board's 1994 ~ighway Capacity Manual, a six-lane roadway is needed to maintain Level of
Service (LOS) D when the ADT reaches 30,000 vpd. Du~ng construction of the project, staff has
indicated that existing businesses in the project area should only be minimally impacted.
?nis portion of Dublin Boulevard is designated as a bike path in the Circulation Element. It is
anticipated thai bicyclists may use Dublin Boulevard as a connection between Iron Horse Trail
(at Scarlett Drive) and the Dublin/Pleasanton BART station (at Iron Horse Parkway). However,
bike lanes are not included in the proposed widening of Dublin Boulevard. The current widening
Dublin Boulevard Widening- CIP 96890 Page 24
plan calls for three lanes (i.e., 15-foot curb lane, and two, 12-foot through lanes) in each
direction. The minimum width for a bike lane is four feet. This is considered a ~votentialty
significant impact. '~
The following mitigation measures are recommended in order to reduce potential transportation
impacts to a level of insignificance.
XV-1. To accommodate bike lanes on Dublin Boulevard, each direction of roadway may
have the following dimensions: 4-foot bike lane, 12-foot curb lane, 11-foot center
through lane, and 12-foot lane closest to the median. Plans indicating this shall be
reviewed and approved by the Public Works Director prior to issuance of ~ading
permits.
XVI. Utilities and Service Systems
a-g - The proposed project includes widening and other modifications to an existing roadway.
The proposed project will require the relocation of a storm drain pipe, to be accomplished by the
Dublin-San Ramon Sanitary District. No impacts to utilities and sen,ice systems are anticipated
