Dear Ms. Bascom:
- Draft Environmental Impact Report
. I Downtown Dublin Specific Plan
Thank you for continuing to include the California Department of Transportation (Department) in
the environmental review process for the Downtown Dublin Specific Plan (DDSP). The DDSP
consists of a comprohensivb set of incentives, standards, and requirements that will implement the
vision for future development in downtown Dublin. The following comments are based on the
Draft Environmental Impact Report (DEIR) dated September 2010.
i
Transportation and Circttiddan
The text of the DER does not adequately discuss traffic impacts to the Interstate 680 (1-680) and
Interstate 580 (I-580) freeway mainline and ramp intersections from diverted Specific Plan area
traffic. Additionally, the Trip Generation Appendix does not include traffic assigned to freeway
mainline and ramps. The impact to the following State facilities should be discussed in greater
detail:
1. I-680 1-1
2. 1-580
3. I-6801I-580 interchange
€ 4. I-680/St. Patrick Way ramps
I j 5. I-680Niliage Parkway ramp
1 6. I-580/San Ramon Road ramps
7. 1-580/Foothill Road ramps
Additional project generated trips on I-680 and 1-580 will result in heavy weaving movements
and a worse Level of Service. The cumulative impact of traffic on the mainline from other 1-2
projects in the vicinity of the study area should be evaluated and appropriate mitigation measures
j should be identified.

Response to Comments
Response to Comment #111
CA Department of Transportation (Caltrans)
November 4, 2010
1-1: Project-related traffic impacts to Interstates 680 and 580 and associated ramps
Impacts to the two freeways are covered in Draft FIR Section 3.9 in the CMA/MTS system
analysis, which covers 1-580 and 1-680 in the vicinity of the Specific Plan, and also via the
intersection analysis for intersections that constitute freeway ramp terminals. The
CMA/MTS system analysis provides PM peak hour volumes both with and without the
Specific Plan, for the Near-Term and Cumulative cases, in Tables 3.9-14 and 3.9-15,
respectively. An analysis is also provided specifically for 1-580 and 1-680 for the AM peak
hour, for the Near-Term and Cumulative cases, in Tables 3.9-16 and 3.9-17, respectively.
Impacts 39-1, 2 and 3 describe the impacts to these systems for the Near-Term/Base FAR
Project, the Near-Term/Max FAR Project, and the Cumulative/Max FAR Project,
respectively. Two freeway segment impacts are identified in Impact 3.9-2 (the Near-
Term/Max FAR Project case): 1-580 eastbound, west of San Ramon Road, in the PM peak
hour, and I-580 westbound, west of San Ramon Road in the AM peak hour. Mitigation
Measure 3.9-1 applies to all 3 impacts and outlines the actions the City will take to help
reduce congestion on the freeways and CMA/MTS systems, thereby reducing these
impacts. However, as noted in Mitigation Measure 3.9-1, the City's ability to restore
acceptable LOS on these segments cannot be assured by the actions, so the impacts
remain significant and unavoidable after mitigation.
Regarding analysis of the freeway interchange ramps: while a direct assessment of ramp
capacity was not performed, the analyses of intersections # 13 (Saint Patrick Way/Amador
Plaza Road/1-680 Southbound Ramps) and # 14 (1-680 Northbound RampsNillage
Parkway) provide an assessment of the operation of the ramp "terminals". In addition, the
analysis of intersection #7 (Dublin Boulevard/San Ramon Road) provides an assessment of
the operation of the closest control point adjacent to the 1-580/San Ramon Road/Foothill
Boulevard interchange, at which most of the ramps themselves are free-flow (i.e., not
regulated by traffic control devices. These analyses, along with the CMP segment analyses
described above, provide an adequate assessment of the Project's impacts on the freeway
system, for a program-level EIR.
A Project Study Report (PSR) to modify both the City of Pleasanton and Dublin portions
of the Interstate 580/Foothill Road interchange was approved by Caltrans in December
2000 and a Project Report (PR) was approved by Caltrans in July 2002. Subsequently, the
City of Dublin has constructed the north side improvements in anticipation of
accommodating increased development in the Downtown area.
The City of Pleasanton is currently preparing Plans, Specifications and Estimate (PSE) for
improvements to the portion of the interchange located in Pleasanton. The traffic forecasts
Response to Comments
being used to evaluate planned improvements to the interchange represent buildout of the
Cities of Pleasanton and Dublin according to their current General Plans. Analysis results
indicate that the eastbound and westbound ramp terminal intersections at Foothill
Road/San Ramon Road would operate at LOS C or better with the improvements that
have already been implemented (in Dublin) and the planned improvements in Pleasanton.
Additional capacity would be provided to accommodate the potential traffic growth
associated with buildout of the Downtown Specific Plan and implementation of the Specific
Plan would have a less-than-sign if cant impact on the interchange.
The comment does not say what additional detail is sought nor does it identify any
inadequacies in the DEIR. As shown above, the DEIR addresses potential impacts and
mitigations at all of the facilities mentioned in the comment. No additional discussion is
required for CEQA compliance.
1-2: Cumulative traffic impacts on Interstates 680 and 580
The analysis described above in response to comment 1-1 includes cumulative traffic
projections. Please see also DEIR Tables 3.9-14 through 3.9-17. The DEIR adequately
analyzes cumulative traffic impacts at a program level; no additional discussion is required
for CEQA compliance. Detailed assessments of freeway operations, such as weaving,
merge and diverge analyses, are typically performed for the traffic operations studies
supporting freeway improvement projects, such as the PSR discussed in response to
comment I -1.
1-3: Stormwater Treatment Construction Improvement Project adjacent to Interstate 680
Comment noted. For any project located within or adjacent to the Stormwater Treatment
Construction Improvement Project will be carefully reviewed by the City of Dublin to
ensure that hydrodynamic separators, culvert pipes, and biofltr-ation swale are not
adversely affected.

Alameda County Transportation Commission
November 3, 2010
2-1: Delete reference to Alameda County Congestion Management Agency
Comment noted. The first sentence of MM 3.9-1 is hereby revised as follows wherever it
appears in the DFIR to reflect the correction and the fad that the City will continue to
impose the identified mitigation measure.
"MM 3.9- 1: As equ y
toe The City of Dublin shall do the following..."
Other references to the Alameda County Congestion Management Agency have been
corrected to ACTC through the Final FIR, but may still be referenced in these responses
where helpful to locate specific discussion in the DEIR.
2.2: Mitigation measure 3.9-1 support of Alameda County transportation projects and
programs
All new development in the Downtown Dublin Specific Plan (DDSP) project area is subject
to the City of Dublin's Site Development Review process. Some projects, depending on
their size and scope, will also require additional traffic and circulation analysis to ensure that
the proposed development works on the site and with the existing transportation
infrastructure. For all projects in the DDSP, City staff will be reviewing project proposals
with an eye for the inclusion of trip reduction programs, good pedestrian and bicycle
circulation and facilities, and transit accessibility. Where appropriate, conditions of approval
will be added to the Site Development Review permit to ensure that such programs and
designs are included in the project.
Through the Site Development Review process, a finding must be made which states that
the project is consistent with the General Plan and any applicable Specific Plans. A finding
also needs to be made that the site has been adequately designed for pedestrians and
bicyclists. Therefore, future projects in the DDSP project area will be required to
incorporate measures to help improve circulation, reduce vehicle trips, and therefore traffic
congestion on the MTS system.
In addition, project developers would be required to pay into the Tri-Valley Transportation
Development Fee (TVTDF) and the Downtown Traffic Impact Fee (TIF), both of which
would contribute toward improvements to MTS roadways.
2-3: Transportation Demand Management Program implementation
Please see response to comment 2-2. As part of the Site Development Review Process,
the City will work with developers to design TDM programs that will ensure that findings
can be made that the projects are consistent with the Specific Plan. TDM program
Response to Comments
elements may include alternative mode use incentives (bike lockers and showers in
commercial buildings), carpool and vanpool matching services, Zipcar sites, bike-share
programs, bus shelters and amenities, site TDM coordinators, as well as other options.
2-4: Applicable City General Plan and Bicycle Master Plan policies that would be
implemented by the developer
The City of Dublin's Bikeways Master Plan (2007) includes several policies that would be
applicable to development projects to be built within the Specific Plan:
Policy 4.6 - As a condition of project approval, require major development projects
with major transportation impacts to construct adjacent bicycle facilities included in
the proposed bicycle system
Policy 4.7 - Evaluate the needs of the community for bicycle parking on a project-
by-project basis
Policy 4.8 - Consult the Recommended Bikeways map prior to implementation of
street improvement projects
Policy 4.9 - Install bicycle stencils and bicycle-sensitive loop detectors (or other
detector type) on bikeways as part of new signals, signal upgrades, and
resu rfaci ng/restri ping projects
Policy 4.10 - Provide appropriately-signed detours for bicyclists during construction
projects.
2-5: Implementation of the Downtown Dublin Traffic Impact Fee (TIF)
The current TIF was adopted in 2004, and includes the following improvements within the
DDSP Study area (refer to Table B-3 from the 2004 Downtown Dublin Traffic Impact Fee
Study Update Memorandum dated September 2004):
Project I - St. Patrick Way Extension
Project 2 - Golden Gate Drive Widening
Project 3 - Dublin Boulevard/Golden Gate Drive Intersection Improvements
Project 4 - Dublin Boulevard/Amador Plaza Road Intersection Improvements
Project 5 - Dublin Boulevard/Dougherty Road Intersection Improvements
Project 6 - San Ramon Road/Dublin Boulevard Intersection Improvements
The City plans to update the TIF following adoption of the DDSP to include additional
improvement projects and to recalculate the fee with consideration of the land use
development changes identified by the DDSP. The DEIR identifies MMs 3.9-1 and -4,
neither of which requires specific roadway improvements. However, it is the intent of the
City to incorporate improvements that are in the Bikeways Master Plan, as well as other
PT I
Response to Comments
improvements that support the goals and policies of the Specific Plan. Thus, development
that is constructed within the DDSP area will be subject to the TIF and will contribute a fair
share toward these improvements.

Dear Ms. Bascom:
Zone 7 Water Agency (Zone 7) has reviewed the referenced Draft Environmental Impact Report
(DEIR) in the context of Zone 7's mission to provide drinking water, non-potable water for
agriculture/ irrigated turf, flood protection, and groundwater and stream management within the
Livermore-Amador Valley. We have the following comment for your consideration.
On page 3-89, under Project Impacts and Mitigation Measures - Place Housing or Structures
Within a 100-year Flood Hazards Area Which Would Impede or Redirect Flood Flows, the third
sentence should be revised to the following:
"In addition, the Zone 7 Stream Management Master Plan proposes projects to retrofit
culverts that carry waters from Dublin Creek under Donlon Way and the unnamed 3.1
drainage feature (Line J-1) which runs parallel to Interstate 680 and crosses under
Interstate 680 just north of Dublin Blvd. These proposed retrofits would increase culvert
capacities and reduce the risk of flooding in the DDSP area. While the projects are
proposed by Zone Ts Stream Management Master Plan, they are not Zone 7 specific
projects."

Dear Ms. Bascom:
Subject: Downtown Dublin Specific Plan - Notice of Availability of Draft Environmental
Report (DEIR)
Reference is made to your transmittal on September 17, 2010, of a copy the Notice of Availability
of the Draft EIR and Notice of Public Meeting for the subject project The Downtown Dublin
Specific Plan consists of a comprehensive set of incentives, standards, and requirements that will
implement the vision for the future development in downtown Dublin.
Per our cursory review of the transmitted material, we hereby offer the following comments
regarding storm drainage that should be considered in the determination of project status:
1. Although the project site is located in Zone 7, runoff ultimately drains to the Alameda Creek
Federal Project in western Alameda County. This flood control facility is maintained by the
Alameda County Flood Control District. The District is concerned with augmentation in
runoff from the site that may impact flow capacity in the Federal Project and in the 4.1
watercourses between the site and the Federal Project, as well as the potential for runoff from
the project to increase the rate of erosion along those same watercourses that could cause
localized damage and result in deposition of silt in the Federal Project. There should be no
augmentation in runoff quantity or duration from the project site that will adversely impact
downstream drainage facilities.
2. The applicant should provide measures to prevent the discharge of contaminated materials I
into public drainage facilities. It is the responsibility of the applicant to comply with Federal, 4-2
State, or local water quality standards and regulations.
I
Thank you for the opportunity to review the Draft Environmental Report for this project. If you

Response to Comment Letter #4
County of Alameda Public Works Agency
October 13, 2010
4-1: Potential stormwater runoff impacts on the Alameda Creek Federal Project in western
Alameda County
Potential drainage and runoff impacts are addressed in Section 3.5 of the DEIR which notes
that the Specific Plan project area is largely built-out with buildings, parking lots, streets, and
sidewalks, with associated landscaping. The goal of the specific plan is to facilitate
redevelopment of the area overtime in a manner that is more pedestrian, bicycle, and
transit friendly, however the area will remain urbanized as it is now. Because the project
area is largely built-out, stormwater flows to collection and distribution systems are
expected to be similar to that which currently exists. The flow capacity is not expected to
increase in quantity or duration, but rather is expected to be reduced with future
development due to improved design and practices and the implementation of better
onsite stormwater detention and management (see especially, Impacts 3.5-3, -4).
4-2: Measures to prevent the discharge of contaminated materials into public drainage
facilities
Comment noted. The DEIR addresses construction and post construction water quality
impacts in Impact 3.5-1.
Subsequent project-specific development applications will be reviewed as to their
consistency with the Downtown Dublin Specific Plan and current City and State regulatory
requirements to control to minimize stormwater runoff and to improve storrnwater quality,
consistent with MMs 3.5-1 a and - I b. These regulations include the requirement to develop
and implement a Stormwater Pollution Prevention Plan (SWPPP) that specifies Best
Management Practices (BMPs) to prevent all construction pollutants from contacting
stormwater and with the intent of keeping all products of erosion from moving off-site into
receiving waters.

Subject: Downtown Dublin Specific Plan Draft Environmental Impact Report
(EIR)
Hello Ms Bascom,
We provide the following comments on the DEIR for the Dublin Specific Plan:
We understand that the proposed City of Dublin Specific Plan will replace and
combine 5 specific plans: Downtown Core Specific Plan, Dublin Downtown
Specific Plan, San Ramon Road Specific Plan, Village Parkway Specific Plan
and West Dublin BART Specific Plan. The Transportation Engineering Division of
Contra Costa County Public Works Department has the following comments on
the Draft Environmental Impact Report (DEIR) for the Downtown Dublin Specific
Plan project:
1. The traffic analysis should include the section of Dougherty Road in
unincorporated Contra Costa County to determine the increase demand on this 5-1
road due to the ultimate build out of the Specific Plan areas. Mitigation measures
should be included to address any impacts.
2. For construction projects in the City of Dublin that would directly impact
County roads, a Traffic Control Plan (including any temporary lane closure, 5-2
flagging, haul routes, detour plans, etc.) would be required to be submitted to
Contra Costa County Public Works Department for review and approval. The
document must address the impacts of any lane closure.
3. On future projects with hauling routes that would impact County roads, a
mitigation requirement should be identified in the report to describe a process
where a pre-project survey of haul route(s) is conducted, thereafter damaged or 5-3
deteriorated pavement resulting from the project truck traffic is identified on the
haul route(s), and measures are implemented to bring the pavement back to pre-
project conditions by the project sponsor at their own cost.

Contra Costa County Public Works Department
November 4, 2010
5-I: Traffic analysis of Dougherty Road roadway segment in Contra Costa County
Consistent with the professional opinion of the traffic consultant and the City's Traffic
Engineer, Dougherty Road was not included in the traffic analysis because the estimated
project trip distribution to this roadway was very low: for commercial trips, I percent in the
AM peak hour and 2 percent in the PM peak hour, and for residential trips, 3 percent in
both peak hours. These percentages were derived from select-zone evaluations for zones
in the DDSP area in the Contra Costa Transportation Authority Travel Demand Model.
5-2: Traffic Control Plan requirement for future projects
Comment noted. The proposed project is a programmatic review of the Draft Downtown
Dublin Specific Plan and does not involve approval of any project specific development
application. For future project-specific development projects that would directly impact
City and/or County roads, a Traffic Control Plan, including any temporary lane closure,
flagging, haul routes, detour plans, etc. would be required to be submitted to the City and
forwarded to the Contra Costa County Public Works Department, consistent with the
development review practices and standard conditions of approval of the City of Dublin.
5-3: Roadway impacts on haul routes for future projects
Comment noted. The proposed project is a programmatic review of the Draft Downtown

application.
As part of any Traffic Control Plan, as discussed in response to comment 5-2, above, the
applicant would be required, consistent with the development review practices and
standard conditions of approval of the City of Dublin, to identify hauling routes that would
impact City and/or County roads. A pre-project survey of haul route(s), identification of
any damaged or deteriorated pavement resulting from the project truck traffic, and
completion of improvements to bring the pavement back to pre-project conditions by the
project sponsor at their own expense, would be required if the truck traffic is estimated to
be significant.

VMT would be 23.4 percent in the same time frame. The VMT estimate is based on the
scenario where not all development is built out in order to be consistent with the 2009-
2015 time frame. Additionally, the DDSP proposes downtown development near transit
and includes extensive policies intended to reduce VMT. The DDSP policies would reduce
VMT by creating a pedestrian-friendly downtown, accommodate alternative transportation
modes (i.e., BART, bus, bicycle, and pedestrian), promote transit-oriented development,
and incorporate mixed-use development into the Specific Plan area. As a result, the growth
rate of VMT under the DDSP would not exceed the growth rate of the population.
According to the current BAAQMD CEQA Guidelines, the VMT growth rate compared to
the City's population growth rate over the same time frame would not hinder progress
towards achieving the goals of the 2005 Ozone Strategy. Therefore, the DDSP is consistent
with the applicable air quality plan, and a less than significant impact would result.

Impact 3.2-3: No major' existing stationary or area sources of toxic air- contaminants
(TACs) were identified in the vicinity of the project area. The DDSP would result in the

sources of TACs from stationary sources. The proposed project would not result in
increased exposure of sensitive land uses in excess of applicable standards. This is

To address community risk from air toxics, the BAAQMD initiated the Community Air Risk
Evaluation (CARE) program in 2004 to identify locations with high levels of risk from TACs
co-located with sensitive populations and use the information to help focus mitigation
measures. Through the CARE program, the Air District developed an inventory of TAC
emissions for 2005 and compiled demographic and heath indicator data. According to the
findings of the CARE Program, diesel particulate matter, mostly from on and off-road
mobile sources, accounts for over 80 percent of the inhalation cancer risk from TACs in
the Bay Area. As of November 2009, the impacted communities include the urban core
areas of Concord, eastern San Francisco, western Alameda County, Redwood City/East
Palo Alto, Richmond/San Pablo, and San Jose.
The CARB Air Quality and Land Use Handbook (April 2005) offers advisory
recommendations for locating sensitive receptors near uses associated with TACs, such as
freeways and high-traffic roads, commercial distribution centers, rail yards, ports, refineries,
chrome platters, dry cleaners, gasoline stations, and other industrial facilities, to reduce
exposure of sensitive populations. No major existing stationary or area sources of TACs
were identified in the project vicinity. The DDSP would result in development within
Downtown Dublin, which may generate sources of TACs from stationary sources. The
development of any new stationary sources of TAC's associated with the DDSP project
area would be subject to BAAQMD rules and regulations and permitting requirements.

To assist Lead Agencies in evaluating air- quality impacts at the neighborhood scale, the Bay
Area Air Quality Management District (BAAQMD) has_ established thresholds of
significance for local community risks and hazards associated with Toxic Air Contaminants
TAC and fine particulate matter (PM2.5 . These thresholds apply for siting a new source
and/or receptor and for assessing both individual source and cumulative multiple source
impacts. For all State highways within the San Francisco Bay Area Air Basin (SFBAAB ,the
BAA MD has made available a set of maps and tables that provide screening-level risks
and PM2.5 concentrations. To develop these tables the BAAQMD selected conservative
assum tp ions and in uts with the following methodolo
. _ Hourly vehicle miles traveled (VMT)_and emissions for 2012 were developed for
each county using the EMFAC model, based on default vehicle mix and full range of
vehicle speeds.
Highest vehicle traffic volumes for each roadway are based on Caltrans's 2007
Traffic Volumes on California State Highways and were scaled based on VMT to
develop hourly vehicle volumes.
Hourly vehicle volume and emissions vrere input into a roadway model,
CAL3QHCR, to estimate annual average concentrations using the most
conservative meteorological data collected from monitoring locations within each
county. CAL3QHCR is an advanced model that process up to a year of hourly
meteorological, vehicular emissions, and traffic volume and signalization data in one
model run In addition I -hour and running 8-hour averages of CO or 24-hour and
annual block averages of particulate matter can be calculated.
For the screening tables, the peak one hour of traffic was used to develop hourly vehicle
volumes that totaled to the annual average daily traffic while risk and hazard tables are
based on annual average daily vehicle volumes. The screening tables are based on the
highest annual average daily_ traffic A( ADT)_for each highway. It should be noted that the
AADT fluctuates depending on postmile, in some cases the traffic may decrease by an
order of magnitude. Therefore, the BAAQMD recommends adjusting the values listed in
the screenin tables to reflect the AADT for a particularpostmile. As a result, the ratio of

the actual AADT to the AAD I used by the BAAQMD was applied to the screening values
to determine the appropriate values for the project site. For example, the screening tables
are based on an AADT of 218,000 and 266,000 vehicles for 1-580 and 1-680, respective.
Based on Caltrans data, the AADT at these locations would be 169,000 and 165,000 for 1-
580 and 1-680, respediv
As indicated in the DDSP, a large portion of the project area is in the vicinity of 1-580 and 1-
680. Based on the adjusted values in the screening tables, the cancer risk and noncancer
hazards generated from the highways would exceed the BAAQMD thresholds at 1,000
feet, which is the BAAQMD recommended screening distance. Therefore, any new
receptors (e.g., residences, schools, etc.) within the 1,000-foot buffer of the highways would
implement specific development standards to reduce exposure to highway pollution.
These development standards are specified within the DDSP and include the following:
Configure the proposed buildings so that the bulk of the building is-located farther
from the highway.
Place heating ventilation and air conditioning (HVAC) system intakes as far away
from highway as feasible.
.-_Include hiRh efficiency filters in the HVAC ystern rated. with a minimum efficiency
ratin value FMERV of at least 13). This would also include a commitment to
regular maintenance and replacement of filters as needed.
Provide positive pressure with the HVAC system in all occupied spaces to prevent
the incursion of outside air that bypasses the HVAC filters.
To reduce the amount of outside unfiltered air indoors, do not place operable
windows in close proximity to the highway. In addition, signs should be posted to
keep exterior dons closed when not in use.
The identification of diesel particulate matter (DPM) as a toxic air contaminant in 1998 led
the California Air Resources Board_(CARB) to adopt the Risk Reduction Plan to Reduce
Particulate Matter Emissions from Diesel-Fueled Engines and Vehicles (Risk Reduction Plan)
in October 2000. The Risk Reduction Plan's goals include an 85 percent reduction in DPM
by 2020 from the 2000 baseline. The Risk Reduction Plan includes regulations to establish
cleaner new diesel engines, cleaner in-use diesel engines (retrofits), and cleaner diesel fuel.
It should be noted that the current emissions factors (FMFAC2007) utilized for the
BAAQMD screening tables do not include emissions reductions from the implementation
of the various measures included in CARB's Risk Reduction Plan. As a result,
implementation of the CARB DPM reduction measures, the 1,000-foot buffer is anticipated
to shrink over time. Based on an 85 percent reduction in DPM at full implementation of
the Risk Reduction Plan, the risk would be reduced accordinn& The Transit Oriented
District has the greatest exposure to 1-580, and upon full implementation of the Risk
Reduction Plan, the 1,000-foot buffer would be reduced to 700 feet.
Air Quality and Greenhouse Gases
Because any new receptors (e.g_ residences schools, etc.) within the 1,000-foot buffer of
the highways would be required to implement specific development standards as defined in
the DDSPP to reduce exposure to highway pollution and implementation of the CARIB
DPM reduction measures_ is expected to be reduce this 1,000 foot buffer distance over-
time, the exposure of sensitive receptors to TACs would be less than significant.
In addition, all projects must implement any applicable air toxics control measures (ATCM).
For example, projects that have the potential to disturb asbestos (from soil or building
material) must comply with all the requirements of CARB's ATCM for Construction,
Grading, Quarrying, and Surface Mining Operations. Compliance with applicable regulatory
standards is required as part of the permitting process for- development and operation of
future development within the DDSP, and would ensure a less than significant
impact.

below the State and Federal standards. Therefore, the proposed project would have a less
Local air- quality is a major concern along roadways. Carbon monoxide (CO) is a primary
pollutant, and unlike ozone, is directly emitted from a variety of sources. For this reason,
CO concentrations are usually indicative of the local air quality generated by a roadway
network and are used as an indicator of its impacts upon the local air quality. Areas of
vehicle congestion have the potential to create "pockets" of CO called "hot spots." These
pockets have the potential to exceed the State ]-hour standard of 20 parts per million
(ppm) and/or the 8-hour standard of 9 ppm.
The BAAQMD requires that proposed projects are analyzed for the potential to cause
localized CO hotspots. Per the BAAQMD CO screening guidelines, a project would have
CO impacts if the following were to occur.
• Project traffic would impact intersections or roadway links operating at level of
service (LOS) D, E or F or would cause LOS to decline to D, E or F.
Project traffic would increase traffic volumes on nearby roadways by 10 percent or
more.
• Project would contribute to CO concentrations exceeding the State Ambient Air
Quality Standard of 9 parts per million (ppm) averaged over 8 hours and 20 ppm
for one hour.
Because traffic congestion is highest at intersections where vehicles queue and are subject
to reduced speeds, these hot spots are typically produced at intersections. Based on the
Traffic Impact Analysis, the intersections listed in Table 3.2-7: Project Buildout Carbon
Monoxide Concentrations, would require a CO hotspot analysis. The BAAQMD
thresholds for CO emissions require projects to perform localized CO modeling. In order

Methodology
Impacts evaluated in this section were assessed based on previously published reports by
the Regional Water Quality Control Board, the California Department of Water Resources,
and information from the City of Dublin General Plan. Impacts to surface and groundwater
quality were analyzed by reviewing existing groundwater and surface water quality literature
that pertain to the project area; identifying existing on-site ground and surface waters, and
evaluating existing and potential sources of water quality pollutants based on the types of
land uses and operational activities that occur or could occur in the DDSP area.
Additionally, the applicability of federal and state regulations, ordinances, and/or standards
to surface and groundwater quality of the project area and subsequent receiving waters
was assessed. The impacts of the proposed project on water resources and water- quality
are evaluated qualitatively.

i
The project area is a primarily urbanized, developed area, which likely already contributes
non-point source pollution such as motor oil, fertilizers and pesticides, human littering,
animal waste and other pollutants typical of developed commercialized areas. These
pollutants are typically washed from streets, parking lots, and garages during rainfall events
that create sufficient runoff to carry the waste materials. These pollutants have the
potential to degrade water quality and may result in potentially significant impacts to the
extent that they are generated by new development. Although the majority of the project
area is built-out, the construction of individual projects would include grading and other
earth moving activities which would expose on-site soils to erosion processes. Additionally,
construction activities could lead to exposure of contaminated materials/soils which if
present within the project area that could impact surface water quality during storm events.
Individual development projects within the project area greater than one acre would be
required to mitigate short-term construction impacts pursuant to the NPDES criteria and
standards on a project-by-project basis. The purpose of the NPDFS permit is to ensure
that the proposed project would eliminate or reduce construction-related sediments and
pollutants during stormwater runoff.
Construction sediment erosion can be adequately controlled through the application of
standard construction BMPs. The goal of BMPs is to capture and treat "first flush"
stormwater run-off generated by surrounding and on-site watersheds. Water quality
management BMPs for grading and construction scenarios may include the use of sand bags
and straw bales for run-off diversion and velocity reduction, mulch topping, hydro-seeding
and siltation fencing to prevent soil loss and measures to minimize vehicular leaking and
spilling. Design guidelines identified in the DDSP encourage increased percolation through
the use of vegetated swales, curb extension, reconfigured parking lots with increased
landscaping, and the use of pervious materials (e.g. pervious pavers) in parking lots.

CMA/MTS System Analysis Results
The Alameda County C-eiwiges~ b Transportation Commission
(A4;C44AACTC) requires analysis of project impacts to Metropolitan Transportation
System (MTS) roadways for development projects that would generate more than 100 PM
peak hour trips. The ^4^CTC. requires that the baseline forecasts be represented by
the model run completed by the ,CTC for 2015 and 2035 conditions. To
complete this analysis, the project traffic, generated and distributed outside of the model as
described in the preceding section, was added directly to the ^'AACTC 2015 and
2035 peak hour model runs. It is noted that a review of the 2015 and 2035
^~,CTC model land use files showed very little growth in the Plan area; thus, this
approach gives a reasonably accurate assessment of the net new traffic added by the Plan
on the MTS roadways.
The MTS system analysis differs from the intersection analysis in the following aspects:
• The regional and local land use data sets used for the intersection forecasts and the
MTS forecasts are different, since the CCTA Countywide Model was used to
develop intersection volumes and the AGGM, ACTC Countywide Model was used
to develop the MTS system forecasts
¦ The MTS roadway analysis reports the outputs of the AGGIM A,ACTC model on a
roadway segment level, as compared to the more detailed intersection turning
movement level forecasts developed for the intersection analysis.
The MTS roadway system in the vicinity of the Project includes 1-580, 1-680, Dublin
Boulevard, and San Ramon Road. The A(;CMAACTC Congestion Management Plan
(CMP) requires this analysis only be done for the PM peak hour, however, Caltrans
requires that it be done for the AM peak hour as well for all Caltrans' facilities. fables 3.9-
