AB a responsible agency under the State CEQA Guidelines, the District is providing this response to the Notice of Preparation. The proposed project is described as including a General Plan amendment, Specific PJan amendment, annexation, and prezoning. The proposed project has potential for environmental impacts re1ated to the Tassajara Creek Regional Trail. Development of the regional trail might need to rely upon the Supplemental Environmental Impact Report. The potential environmental impacts, and a reasonåble alternative aliV1ment of the regional trail, should be discussed in the Supplemental Environmental Impact Report. Tassaiara Creek Regional Trail As part of the implementation of the District's adopted Master Plan 1997, the District seeks to develop the Tassajara Creek Regional Trail from Dublin Blvd., through the proposed project, continuing northward and eventually connecting to Mt. Diablo State Park. The District controls (through a combination of ownership and easements) the Tassajara Creek Regional Trail corridor, which is located immediately adjacent to the proposed project area. Currently, this corridor is 22.8 acres in size with minimal facilities, consisting of a picnic table, restrooms, and bridge over Tassajara Creek. The regional trail coIridor includes lands on Parks Reserve Forces TraiDing Center (Camp Parks) which is adjacent to the proposed project.

'E ~ C Q ~ " ~ The three (3) most significant environmental issues of the proposed project for the District are: 1) the loss of open space lands available for the regional trail corridor; 2) the proposed expansion of residential development on the ridgelands over looking the regional trail corridor; and 3) without provision in the proposed project for a reasonable alternative alignment for the regional trail, and with the potential conflicts ~th resource protection policies of the regulatory authorities (Fish and Wildlife Service, Department ofFish and Game), the proposed project effectively precludes the completion of this segment of the regional trail. Detailed environmental issues Initial Study. Section IX Land Use and Planning The proposed project would appear to be in conflict with the East Bay Regional Park District Master Plan 1997. The Master Plan includes the development of the Tassajara Creek Regional Trail :trom Dublin Blvd. to Mt. Diablo State Park. The Master Plan allows some flexibility in the specific alignment so that there can be a balance between conserving resources an.d providing recreational uses. The proposed project seems to lack a reasonable alternative alignment for the regional trail. The proposed project would appear to be in conflict with the Dublin General Plan and the Eastern Dublin Specific Plan. The proposed project seems to be inconsistent with the Dublin General Plan Land Use Element, Open Space Element, and open space action program which provide for a significantly larger amount of open space land that would be available for the regional trail corridor. The proposed project would provide a narrow corridor for the regional trail. The proposed project seems to be inconsistent with the Eastern Dublin Specific Plan land use policies for the Foothill Residential subarea. The intent is to preserve the ridgelands and higher elevations within the subarea as open space. The proposed project would enlarge the amount and area of residential development on the ridgelands over looking a much reduced regional trail corridor. 2 ,. The proposed project seems to be inconsistent with the Eastern Dublin Specific Plan traffic and circulation policies, and resource management policies. The policies call for a north-south trail generally along Tassajara Creek., connecting with areas both north and south as part of a larger regional trail network. The regional trail is supposed to be balanced with resource protection in the open space network in consultation with the regulatory agencies. To the extent that a regional trail corridor along Tassajara Creek might conflict With resource protection policies of the regulatory authorities, an alternatiye alignment would be through the open space corridor on the ridgelands and higher elevations. The proposed pròject would seem to result in either I) a regional trail corridor alignment potentially in conflict with resource protection policies of the regulatory authorities (Fish and Wildlife Service, Department ofFish and Game), or 2) allow an alternative alignment within an open space corridor much narrower than the General Plan and Specific Plan provide for. The net effect might be to preclude the completion of this segment of the regional trail. Initial Study. Other Sections The SEIR should also discuss the other potentially significant issues that were identified in the Initial Study. Alternative The SEIR should explore a reasonable alternative with a regional trail corridor on an alignment on the ridge lands and higher elevations that are within an open space area as large or larger than that identified in the General Plan and Specific Plan. Perhaps some of the residential density proposed on the open space area could be transferred to areas designated in the General Plan and Specific Plan for residential development.

The DSEIR evaluates the potential environmental impacts that might reasonably be anticipated to result from the proposed Project, which includes a reorganization to annex the Wallis Ranch, Sperfslage, and .Bragg to the City of Dublin and Dublin San Ramon Services District. The Proj ect area consists of about 188 acres of land in an unincorporated area of Alameda County. The DSEIR is being prepared because conditions related to agricultural resources, biological resources, noise, public services (schools), transportation and circulation and utilities service systems may have changed since the Eastern Dublin Environmental Impact Report was prepared. The original Eastern Dublin Environmental Impact Report was prepared in 1992 and was certified by the City of Dublin in 1993. Regional Board staff have the following comments on the DSEIR. Comment 1 Initial Study, Section 8, Hydrology and Water Quality, Project Impacts and Mitigation Measures, a) violate any water quality standards or waste discharge requirements, page 40. Text in this section of the Initial Study refers to post-construction Best Management Practices (BMPs) to mitigate for the impacts of the Proj ect on stormwater runoff quality and quantity. Since the original EIR for the Project was prepared in 1992, . please verify that the proposed mitigation measures are still consistent with Alameda . County's National Pollutant Discharge Elimination System (NPDES) permit for stormwater discharges. Under the terms of the NPDES permit, post-construction best management practices (B:MPs) are to meet the maximum extant practicable (MEP) definition of treatment specified in the Clean Water Act (CW A). Cities in Alameda County are implementing the current NDPES permit for discharges of stormwater under the Alameda Countywide Clean Water Program, Storm water Management Plan (S:MP) R (BOA, Inc., February 1997). New Development and Construction Goals are discussed in ¡_,.. EcelV@'rftion 7 of the SMP. These goals include the following: ,. tB 2 ß 2003 f1U13l.1N PI A ru . <..Jot1'llN1MG California Environmental Protection Agency o Recycled Paper Mr. Peabody - 2 - Wallis Ranch Reorganization NOP for DSEIR · Incorporate stormwater quality controls into the plarming and permitting of new development/significant redevelopment projects; · Continue to promote implementation of the Regional Board Staff Recommendations for New and Redevelopment Controls for Stormwater Programs. Tables 2 and 4 of the Regional Board Staff Recommendations for New and Redevelopment Controls for Stormwater Prpgrams state that residential and commercial projects with greater than five acres of directly coupled impervious area are required to implement Tier 3 post-construction stormwater best management practices (BMPs). Tier 3 BMPs are required to be treatment controls that are based on performance goals, including a reduction by 80 percent of the annual total suspended solid loadings expected from the site in its developed condition. Appropriate Tier 3 controls are specified as: wet ponds; constructed wetlands; swales and vegetated filter strips; extended detention basins; and sand filters. The Alameda County NDPES permit was re-issued on February 19, 2003. New development and significant redevelopment Projects that are constructed after February of 2005 will be required to comply with the numeric standards for post-construction stormwater BMPs in the re-issued permit. Treatment BMPs are to be constructed that incorporate, at a minimum, the following hydraulic sizing design criteria to treat stonnwater runoff. As appropriate for each criterion, local rainfall data are to be used or appropriately analyzed for the design of the BMPs. Volume Hydraulic Design Basis: Treatment BMPs whose primary mode of action depends on volume capacity, such as detention/retention units or infiltration structures, shall be designed to treat stormwater runoff equal to: 1. the maximized stormwater quality capture volume for the area, based on historical rainfall records, determined using the formula and volume capture coefficients set forth in Urban Runoff Quality Management, WEF Manual of Practice No. 23/ ASCE Manual of Practice No. 87, (1998), pages 175-178 (e.g., approximately the 85th percentile 24-hour storm runoff event); or . 2. the volume of annual runoff required to acbieve 80 percent or more capture, determined in accordance with the methodology set forth in Appendix D of the California Stormwater Best Management Practices Handbook, (1993), using local rainfall data. California Environmental Protection Agency ~cled Paper Mr. Peabody - 3 - Wallis Ranch Reorganization NOP for DSEIR Flow Hydraulic Design Basis: Treatment BMPs whose primary mode of action depends on flow capacity, such as swales, sand filters, or wetlands, shall be sized to treat: 1. 10% of the 50-year peak flow rate; or 2. the flow of runoff produced by a rain event equal to at least two times the 85th percentile hourly rainfall intensity for the applicable area, based on historical records of hourly rainfall depths; or 3. the flow of runoff resulting from a rain event equal to at least 0.2 inches per hour intensity. Regional Board staff strongly encourage the use of landscape-based stonnwater treatment measures, such as biofilters and vegetated swales, to manage runoff from the project sites. Since landscape-based stonnwater treatment measures require that some of the site surface area be set aside for their construction, the proper sizing and placement of these features should be evaluated early in the design process to facilitate incorporation of the features into the site landscaping. Regional Board staff discourage the use of inlet filter devices for stormwater management. Filtration systems require a maintenance program that is adequate to maintain the functional integrity of the systems and to ensure that improperly maintained filtration devices do not themselves become sources of stormwater . contaminants or fail to function. Regional Board staff have observed problems with the use of inlet filter inserts, since these devices require high levels of maintenance and are easily clogged by -leaves or other commonly occurring debris, rendering them ineffective. Research conducted by the California Department of Transportation has demonstrated that inlet filters can be clogged by a single storm event. The study found that these devices required maintenance before and after storm events as small as 0.1 inch of rain. In addition, trash, debris, and sediment in the catchment had a significant impact on the frequency of maintenance. Therefore, adequate maintenance of inlet filters to provide MEP water quality treatment would be prohibitively expensive and impractically time consummg. Regional Board staff recommend that the City refer to Start at the Source, a design guidance manual for storm water quality protection, for a fuller .discussion of the selection of stormwater management practices. This manual provides innovative procedures for designing structures, parking lots, drainage systems, and landscaping to mitigate the impacts of stormwater runoff on receiving waters. This manual may be obtained from most cities' planning departments, or by contacting the San Francisco Estuary Project (510-622-2465).

The Environmental Setting description on page 39 notes that there are intermittent unnamed streams and defined drainages in the Project area. Please verify that the mitigation measures referenced on pages 40 and 41 note that these unnamed streams and defined drainages are regulated as waters of the State by the Regional Board and may also be regulated as waters of the United States by the U.S. Army Corps of Engineers (Corps). Mitigation measures should note that discharges offill to waters of the United States (e.g., channel re-alignments, channel culverting, construction of outfalls on the banks of channels, armoring of channel banks, etc.) must be authorized by the issuance of a permit from the Corps under Section 404 of the Clean Water Act (CW A). Permits issued by the Corps under Section 404 of the CW A are not valid until they have been certified by the Regional Board under Section 401 of the CW A. The mitigation measures should also note that activities in areas that are outside of the jurisdiction of the Corps (e:g., isolated wetlands, vernal pools, or stream banks above the ordinary high water mark) are regulated by the Regional Board, under the authority of the Porter-Cologne Water Quality Control Act. Activities that lie outside of Corps jurisdiction may require the issuance, or waiver, of waste discharge requirements from the Regional Board.

The IS contains the proposed scope and content of a supplement to the Dublin General Plan and Eastern Dublin Specific Plan Environmental Impact Report (DGP-EDSP EIR). The U.S. Anny is required to train units in the defense of our nation and Parks RFf A plays an important role in that mission. Parks RFf A provides administrative facilities and approximately 2,000 acres of open grassland for year-round training. Chapter 11 (noise) of the IS states that no further analysis is required for noise impacts from military operations at Parks RFf A because the impact was identified as significant and unmitigatable in the DGP- EDSP EIR. The DGP-EDSP EIR states, however, that development in the Foothill Residential and Tassajara Village Center Planning Subareas (of which Wallis Ranch is part of) requires an acoustical . stUdy (MM 3.10/4~0). The DGP-EDSP Effi; states that the purpose of the study would be to identify all potential noise-generating operations and determine if future noise levels will exceed the acceptable levels as defined by the City and Anny. The DGP-EDSP EIR also reconnnends that mitigation measures be developed from the results of the study. A nwnber of training activities, including·artillery bombardment simulations, tactical vehicle operations, field training exercises, and military helicopter operations, may occur within 330 feet of proposed mediwn-high density residential development. Building sensitive noise receptors such as houses so close to military activity warrants detailed acoustical analysis and appropriate mitigation measures. We request that a detailed acoustical study with recommended mitigation measures be performed. We also request that prospective residents be fully informed of the potential noise they will be exposed to. Parks RFTA is referred to incorrectly as Camp Parks Reserves Forces Training Area. The COITect title is Parks Reserve Forces Training Area or Parks, RFT A. Please contact Mr. Paul Kot (925) 875-4682 with any questions.

BAY AREA AIR Ü1lALITY MANAGEMENT DISTRICT ALAMEDA COUNTY Roberta Cooper Scott Haggerty (Chairperson) Nate Miley Shelia Young RECEIVI=I) MAR 1 4 2uU3 DUBUN PLANNING March 14, 2003 Eddie Peabody, Jr. Development Services Department City of Dublin 100 Civic Plaza Dublin, CA 94568 Subj ect: Wallis Ranch Reorganization and Development Project Dear Mr. Peabody: Bay Area Air Quality Management District (District) staff have received your agency's Initial Study and Notice of Preparation (NaP) of a Draft Supplemental CONTRA COSTA COUNTY Environmental Impact Report (DSEIR) for the Wallis Ranch ReorgaIÚZation and Mark DeSaulnier Development Project. The Wallis Ranch project includes the annexation and pre- G~f: ~~~a zoning of three parcels in Eastern Dublin. The proposed land uses include up to (Secretary) 1,124 residential units, 7,841 square feet of neighborhood commercial uses, 82 acres of open space and a 5-acre neighborhood park. MARIN COUNTY Harold C. Brown, Jr. District staff agree with the NaP's conclusion that the DSEffi. should analyze NAPA COUNTY the project's potential impacts upon air quality. The Bay Area is currently a non- Brad Wagenknecht attainment arFa for federal and state ambient air quality standards for ground level SAN FRANCISCO COUNTY ozone and state standards for particulate matter. The air quality stapdards are set at Willie Brown, Jr. levels to protect public health and welfare. As general background for readers, the Jak~h~~g~~rick DSEJR should di~cuss the health effects of air pollution, and it should provide quantitative summaries of the region's attainment status with regard to ambient air quality standards and the contribution of mobile and stationary sources to air pollution emissions. SAN MATEO COUNTY Jerry Hill Marland Townsend (Vice-Chairperson) SANTA CLARA COUNTY Liz Kniss Julia Miller Dena Mossar (Vacant) SOLANO COUNTY John F. Silva SONOMA COUNTY Tim Smith Pamela Torliatt William C. Norton EXECUTIVE OFFICER/APCO The DSEJR should also evaluate potential nuisance impacts, such as odors and dust that could result from project implementation. Odors and dust may not necessarily cause physical harm, but can still be unpleasant and can motivate citizen complaints. Odor and dust from nearby agricultural uses might impact new residents and other sensitive receptors. Particulate matler (PM) is a pollutant of concern for both nuisance and health-related reasons. PM larger than ten microns is more likely to be a public nuisance than a serious health hazard. On the other hand, research has demonstrated a correlation between high levels of fine PM and increased mortality rates and high incidences of chronic respiratory illness. The DSEIR should evaluate potential impacts and propose appropriate mitigation measures. The DSEJR should analyze the potential impact on air quality from proj ect construction and project operation at buildout. We understand that the project area was included in a Program Environmental Impact Report, the Eastern Dublin ErR, which was certified by the City·in 1993. According to the Initial Study, the Wallis Ranch project proposes a higher rate of urbanization than was addressed in the earlier Eastern Dublin EJR; therefore the previously adopted air quality mitigation 939 ELLIs STREET' SAN FRANCISCO CALlFOP,NIA 94109· 415.771.6000' wlUw.haaqmd.go/i Mr. Eddie Peabody -2- March 14,2003 measures may no longer be adequate. Without appropriate mitigation, a project of this size is likely to have significant air quality impacts through an increase in motor vehicle traffic. Motor vehicles constitute the largest source of air pollution in the Bay Area; therefore, we are concerned about the air quality impacts of automobile use from this project. District staff have concerns about the project's potential air quality impacts. While we are generally supportive of providing more housing in the region, the location and density of new residential development and its proximity to services is extremely important. The District is in favor of appropriate infill development that is of a moderate to high density, has a variety ofland uses and encourages alternative modes of transportation. Such projects are generally much less automobile-dependent and thereby generate less air pollution than conventional sprawl development. District staff believe that the urban fringe is an inappropriate location for the level of development proposed for the Wallis Ranch project. We consider the development of residential units on infill properties near transit to be a more sustainable approach to providing additional housing in the region. As part of the Regional Agencies Smart Growth Strategy/Regional Livability Footprint Project, Alameda County residents recently expressed a strong preference for more infill and mixed use development that provides a range of travel options. We strongly recommend that the City implement smart growth strategies that have emerged from that region-wide planning process. District staff encourage the City to consider accommodating future growth by channeling housing and infrastructure investments to central Dublin, other existing urbanized areas, or along transit corridors where development would be less reliant on automobiles. The approval of projects like Wallis Ranch eliminates much of the incentive to take advantage of infill opportunities. We encourage the City to make land use decisions that support transit, walking and cycling, in order to reduce the rate of increase in vehicle miles traveled and improve local and regional air quality. If the City decides that the Wallis Ranch site is an appropriate location for development, then we recommend that the City mitigate the potential air quality impacts of this project as much as possible. First, the Initial Study makes no mention of transit service to the Wallis Ranch site. Motor vehicles constitute the largest source of air pollution in the Bay Area; therefore, the District has a strong interest in promoting alternative modes of transportation. A project oftbis size located at the periphery of the region is likely to have significant air quaiity impacts through a substantial increase in motor vehicle traffic. Currently, the nearest Livermore Amador Valley Transit Authority (LA VIA) bus line is almost 2 miles away from the project site. This lack of public transit options is a cause for concern to District staff. In both the air quality and transportation sections, the DSEIR should provide detail on how the project proponents will work with LA VTA to provide transit services to the Wallis Ranch area. Second, the City should consider reworking the land use component oftbis project to make it less auto-dependent. The project should incorporate more neighborhood-serving commercial and community uses throughout the plan area, not just on the Bragg Property in the eastern portion of the project area. Finally, the commercial and community uses should be located within close proximity to the residential units and be pedestrian and bicycle accessible. If shops and community services are in walking or biking distance from homes, residents will be Mr. Eddie Peabody -3- March 14, 2003 less likely to drive and fewer vehicle trips will be generated, thereby reducing the air quality impacts of the development. For the residential uses, we recommend including on-site measures to mitigate the air quality impacts of traffic generated by the project. If LA VTA cannot provide public transit service to the site, the project sponsors could work together to provide a private shuttle service from the Wallis Ranch area to the Dub1in/Pleasanton BART station and other activity centers. We suggest that shuttle services be closely monitored and adjusted as necessary to assure that the number and scheduling of shuttles provides prompt, convenient service. In addition, the project sponsors could provide small electric vehicles for shared use by residents to access nearby transit nodes and to use on other short, local trips within a certain vicinity of the development. Additionally, the City should require the project sponsors to link the site's proposed bicycle and pedestrian system with the greater local and regional bicycle route network. If significant air quality impacts are identified, the DSEIR must include all feasible mitigation measures to reduce those air quality impacts. If air quality impacts cannot be reduced to a level less than significant, project alternatives should be identified that would not result in significant air quality impacts. District staff recommend the City analyze an off-site alternative that would accommodate the same amount of proposed residential units on infill sites located closer to existing transit and services. For more detailspn our agency's guidance regarding environmental review, we recommend that the City refer to the BAAQMD CEQA Guidelines: Assessing the Air Quality Impacts of Projects and Plans (1999). The document provides information on best practices for assessing and mitigating air quality impacts related to projects and plans, including construction emissions, land use/design measures, project operations, motor vehicles, nuisance impacts and more.

We have several comments which are made in the context of Zone 7' s responsibilities in our service area to provide wholesale treated water, non-potable water for agriculture and irrigated turf, flood protection, and groundwater and stream management. Our comments are listed below and are organized to follow the order of the environmental checklist in this Initial Study: 1. Project BackgrOlmd and Description - Infrastructure, page 5 Tassajara Creek, extending from the southerly boundary of the project to approximately 2,100 feet south of the Alameda C01.mty/Contra Costa County line, and an approximate 400-foot long reach of the tributary to Tassajara Creek, are authorized Zone 7 facilities. If any alteration of Tassajara Creek or the tributary are proposed, then a hydraulic study of the effect of such alteration on the water surface under the 1 DO-year flow conditions and the proposed development should be submitted to Zone 7 for review and comment. 2_ Section 8, Hydrology and Water Quality, item c), page 41 Mitigation for the creation of new impervious areas within the Livermore-Amador Valley is addressed through the collection of Special Drainage Area (SDA) 7-1 drainage fees. Zone Ts standard mitigation practice is to collect an SDA 7-1 fee on any new buildings, improvements ..(incIuding, but not limited to paving), or structures to be constructed that substantially increase the imperviousness of the land surface. 3. Section 8, Hydrology and Water Quality, item e), page 41 A hydrology study is needed to detennine the impacts to Zone 7' s facilities.

Section 13, Public Services, Water and Sewer, page 46 This project will also be annexed to DSRSD for water and sewer services and DSRSD's master utilities plans, including recycled water, will cover this project area. The Initial Study does not assess the potential salt loading impacts over our main groundwater basin. Zone 7 considers all applied water (rainwater is an exception), including both potable water and recycled water, to contribute salt loading to the groundwater basin and there must be mitigation of the associated impacts. Zone 7's GToundwater Demineralization Project is the recommended project to accomplish Zone 7's Salt Management Program's goal cfnqn-degradation of ourmaiTI groundwater basin from the long-term buildup of salts. Zone 7 expects to begin design in 2004, with project completion expected in 2006. We request that the City of Dublin express support for the Groundwater Demineralization Project within the Draft EIR as the appropriate mitigation for any projects proposed. Otherwise, we request the City address the mitigation of any salt loading impacts of the project should Zone 7's proposed Groundwater Derrrineralization Project not be constructed and placed into operation. 6. Section 16, Utilities and Service Systems, item d), page 52 A portion of the project area is located in Contra Costa County. Zone 7's service area is in Alameda Cóunty.
