ADOPT Resolution (Attachment 3) approving a waiver tol The Inclusionary Zoning Ordinance per Section 8.68.040.E .... ..~- .'fm_- Pursuant to the City's Memorandum of Understanding with BART and the City of Pleasant on, the tax revenues generated from th~ development ofthis project have been pledged toward the payJ.ent of future debt service associated with a bond issue for construction ofthe BART station. ! I I In 2000, the City Council approved three downtown specific plans aimed at guiding future developJent in Downtown Dublin. One of these specific plans covered the area south of Dublin Boulevard between Highway 680 and San Ramon Road, where the future West Dublin/Pleasanton BART Station is pro~osed to be built. The West Dublin BART Specific Plan outlined a design for the redevelopment of th~ area around the future transit station, envisioning a mixture of office, hotel, and residential uses. I ! I Two of the properties closest to the future station have submitted applications for new development lin the area. The subject proposal will help bring this area one step closer to realizing its ultimate development as a transit village. I FINANCIAL STATEMENT: BACKGROUND: PROJECT DESCRIPTION: ' The proposed project consists of a West Dublin BART Specific Plan amendment, Planned Develo~ment Rezoning, and related Stage I Development Plan and to permit 210 apartments, a I50-room hote~, and 7,500 square foot small-scale commercial pad on approximately 7.26 acres at 6600 Golden Gate prive, adjacent to the future West Dublin BART station. The Applicant is also requesting a waiver to the I Inclusionary Zoning requirements per Section 8.68.040.E of the Dublin Municipal Code. I The bigh-density residential portion of the development would be located on the southwest comer IOf S1. Patrick Way and Golden Gate Drive, and is proposed as a four-story building wrapped around stru~tured parking. The hotel portion of the project would be located closest to Highway 580, and is proposeh as a five-story hotel with . surface parking and some parking within the future BART garage (which Jill be built on a separate parcel). The small-scale commercial portion ofthe project would be located at t~e end I I I J-~ I of Goiden Gate Drive, closest to the future BART station pedestrian bridge entrance. The SingJstory building will share the same surface parking lot as the hotel, and could be developed as any raJge of commercial uses, including restaurant, retail, office, or other small-scale commercial uses. At thi~ time the Applicant is considering both possibilities. This flexibility can be preserved as long as total v1ehicle trips generated by the entire project is at or below that which has been studied and documented ~n the Initial Study and Addendum (Exhibits 1 and 2 to Attachment 1). ; ANALYSIS: Rezoning: The Stage I Development Plan, which contains greater detail regarding the project, is included as Exhibit 1 to Attachment 2 of this report. This section will briefly analyze each item of the Stage 1 Develop~ent Plan. i I 1. Zoning. The zoning for the property is currently Planned Development (West Dublin :BART Specific Plan). The development standards for this zoning district are those that are contaihed in the West Dublin BART Specific Plan, which permits residential uses on the northern port~on of the property, and hotel uses on the southern portion of the property. Since the Appliqant is proposing slightly different uses at different densities than is permitted in the Specifiq Plan Planned Development zoning, the Stage I Planned Development Zoning District will need! to be changed to reflect the new Stage I Development Plan (see table under no. 8 below). 1 I 2. Statement of Proposed Uses. The proposed uses for the site include a 210-unit, four-story,: high- density residential apartment project, a 150-room hotel, and a 7,500 square foot ancillary full- service/quality restaurant or retail establishment. These uses are permitted on the site ass1uning that the development regulations of the Dublin Zoning Ordinance can be met. No uses are I permitted by Conditional Use Permit. ! 3. Stage 1 Site Plan. The Stage 1 Site Plan is a generalized, schematic depiction of the locat~on of the proposed uses on the site. Minor adjustments to internal vehicle circulation routes, ped~strian connections between the project, the future land uses to the west, and the BART station, Ptrrking requirements and layout, and a more precise site plan will be developed at the subsequep.t PD Zoning District/Stage 2 Development Plan. Precise roadway arid infrastructure improvements, which have already been discussed preliminarily, will also be formalized in the Stage 2 Development Plan. ! . I 4. Site Details. The Project site is a total of7.26 acres. By use, the site areas will be as follow~: 3.65 acres for residential, 2.43 acres for hotel, and 1.16 acres for small-scale commercial uses. : 5. Maximum development densitvpermitted. The maximum density for the residential portion!ofthe project will be 58 units per acre (maximum of 210 units). The maximum square footage for the hotel portion of the project is 79,500 square feet (maximum of 150 rooms). The maximum fquare footage for the small-scale commercial portion of the project is 7,500 square feet. i 6. Phasing Plan. It is anticipated that the construction of the apartments will commence by the bnd of 2004 and will be completed by December 2005. As part of the residential phase bf the development, approximately 1/3 of the length of the future St. Patrick Way will be built to! serve this project. The remaining 2/3 of the road will be built when the office/residential development to the west is constructed. In the case that the office/residential project to the west develops fiist, the entire length of St. Patrick Way will be built at that time. The hotel and ancillary smad-scale I commercial portion of the project is anticipated to be under construction from Octoben 2006 through December 2007. i : 7. Conceptual Landscape Plan.

I .1 9. InclusIOnary ZOlllng RegulatIOns. In accordance wIth CIty polIcy, the ApplIcant shall comply wIth Chapter 8.68 of the Dublin Zoning Ordinance, Inclusionary Zoning Regulations, and any City Council Resolution relating to that ordinance in effect at the time of the issuance of thb first building permit for this project. Section 8.68.040.E allows for the City Council to waive, ~holly or partially, the requirements of the Inclusionary Zoning Ordinance at their discretion. i The Applicant has requested such a waiver and this request is discussed in a separate section 9f this ~~. I I 10. Aerial Photo. Attached to the Stage I Development Plan. I I Amendment to the West Dublin BART Specific Plan I On August 192003, the City Council adopted a resolution approving a Specific Plan Amendment I Study request for the project. In order to permit this application as proposed, the West Dublin BART Specific Plan would need to be amended as described below. Exhibit 1 to Attachment 1 illustrates the prdposed land use designation change. I I I 1. Change in maximum permitted density on the residential site from 160 dwelling units (45 units/acre) to 210 units (58 units/acre) in Table 5, Maximum Economic Development potent1al. 2. Change text of Residential land use category to state that a high density range of 30 ItO 58 units/acre may be acceptable. The textual description of the residential land use category I states that a high-density range of 30-50 dwelling units/acre ~ay be acceptable in this locationj The Applicant's proposal is for a density above this range, and the Specific Plan text would nee4 to be amended accordingly. I 3. Change in land use designation for a small part of the southern portion of the site ~om L (Lodging), which permits hotels and ancillary uses, to Commercial (B), which permits resta~rants, retail and other smaller-scale commercial uses. The Applicant's proposal is for a quality rest~urant or small-scale retail establishment that is supplemental to, and separate from, the hotel. IThese uses are not expressly permitted in the L (Lodging) category, so a portion of the site currently designated for the hotel will be changed to commercial uses, as illustrated in Exhibit 1 to I Attachment 2. I I Yl5b1 Request for Inc1usionarv Waiver: Chapter 8.68 of the Dublin Municipal Code requires all new residential development projects of 2d units or more designed and intended for permanent occupancy to construct 12.5% of the total number of I dwelling units within the development as affordable units, except as otherwise provided by the chap~er. The Applicant is requesting a waiver of the City's Inclusionary Zoning Regulations under S~ction 8.68.040.E, which states "The City Council, at its discretion, may waive, wholly or partiall~, the requirements of this ordinance and approve alternate methods of compliance with this chapter !if the applicant demonstrates, and the City Council finds, that such alternate methods meet the purposes 9f this chapter." . i The apartment portion of the project is part of the larger West DublinlPleasanton BART statiql and Transit Village development. Income generated from the development ofthe private parcels in the 1i'ransit Village -- in the way of ground leases, BART ridership and municipal taxes -- will go to pay ~or the construction of the BART station. To adequately fund the station construction, it is necess~ry to maximize the proceeds from the private parcels. Waiving the Inc1usionary Zoning Regulatioh will increase the value of the land, increase the proceeds from the ground leases for the station, and ~educe amount of the revenue bonds necessary to pay for the balance of the station construction. The City ~s also part of an agreement with BART to contribute City tax revenues, generated as a result of the ~rivate development in Dublin, to the debt service for the revenue bonds. The City will be relieved: of its obligation within a certain window of time after the opening of the station. . Maximizing the pn?ceeds from the private development could allow the City to be released from their obligation soo~er by increasing the property value, increasing the property tax proceeds, retiring the debt sooner, and tnereby shortening the time where the City would need to contribute their tax revenues to bond service. i Proceeds from the proposed development project will provide a critical piece of the funding for the Ifuture West Dublin/Pleasanton BART station. By granting a waiver to the Inclusionary Zoning regulatio~s, the development project will be more viable and profitable, and thereby increasing the funds avail~ble to construct the future BART station in a timely fashion. Once the West Dublin/Pleasanton BART station is under construction, property near the station and in Downtown Dublin will become viable for resi4ential uses and new opportunities for affordable housing will be introduced to the community. Althou~ the project itself may not provide affordable housing units, through the development of the BART sta~ion, it will influence the development of future residential projects that will contain units affordable to a rahge of income categories. Staff finds that the approval of the waiver could jump start residential developnient in the area and eventually result in an increase in the production of affordable residential units, which lis one of the purposes ofthe Inclusionary Zoning regulations per Section 8.68.010.A ofthe ordinance. : Staff supports approving the waiver request, but resolutions both approving and denying the ~aiver request are included with this Staff Report as Attachments 3 and 4 for the City Council's revie~ and consideration. ! Environmental Review: ; On February 8, 1990, the BART Board of Directors approved the extension of the BART transpo~ation system to Dublin and Pleasanton. Along with approval of the Dublin/Pleasanton extension, they c~rtified an Environmental Impact Report that evaluated the environmental impacts associated with extendipg the BART rail line through the Livermore/Amador Valley area into the communities of Castro Valley, Dublin, Pleasanton, and Livermore. ! I In 2001, the BART Board of Directors finalized plans to construct the West Dublin/Pleasanton 1ART Station and the joint development of BART-owned pieces of property in both Dublin and Plea~anton, I i I bOO' including the project site. In approving the plan, BART, as the lead agency, certified a SUPPlement~l EIR for the West Dublin/Pleasanton BART Station and Transit Village Project on April 2, 2001. BARTl is the lead agency for this project, and the City is a responsible agency under CEQA. As a responsible a$ency, the City's role is very limited. Rather than certify Lead Agency's document as adequate, <CEQA Guidelines require the decision-making body of a responsible agency only to certify that it review~d and considered the information contained in the EIR prepared by the Lead Agency. I The City reviewed and commented on the Draft SElR when it was circulated in 2000 and had sUb~tted comments on noise impacts, issues regarding parking provided by the proposed project, and pqssible traffic impacts ofthe development. These concerns were addressed in the Final SEIR and the City ~id not challenge the response. I I I This project is within the boundaries of the West Dublin BART Specific Plan area. The Specific Pldnwas I adopted on December 19, 2000 and is intended to guide future development in the area. A Negative Declaration was also adopted on the same date that provided an environmental analysis for thel three downtown specific plans together. For the subject site, the West Dublin BART Specific Plan enviSioned the development of a 240-room hotel and 160 high-density residential units, and the Negative Decl~ration examined the potential impacts of such a project. : However, the development that is now proposed to take place on the Dublin parcel is slightly dJferent than the project that was analyzed in both the Supplemental EIR and the Negative Declaration pr~pared for the Downtown Specific Plans. In order to determine if there were any environmental impacts that are present with the revised project proposal that were not already addressed (and mitigated if necess4ry) in the Supplemental EIR or the Negative Declaration, an Initial Study was completed (Exhibi~ 2 to Attachment 1). The Initial Study, dated January 12,2004, determined that the potentially significant effects of the project were adequately addressed in both the Supplemental EIR and Negative Declatation. No significant new information has arisen for this project during the preparation of the Initial Study that would require further environmental review. An Addendum to the Supplemental EIR and Ne~ative Declaration has been prepared which notes the minor land use changes and their relation to the ce~ified Supplemental EIR analysis and Negative Declaration (Exhibit I to Attachment 1). : The ApplicantlDeveloper is required to comply with all applicable action programs and mitikation measures of the Final West Dublin/Pleasanton BART Station and Transit Village Project Supple~ental Environmental Impact Report (SEIR), the Final Dublin/Pleasanton Extension Project EIR, and the I Mitigation Monitoring and Reporting Plan (MMRP) certified and adopted by the Bay Area Rapid Transit District (BART) Board of Directors. I I Additionally, the ApplicantlDeveloper shall comply with all applicable action programs and mitikation measures of the Negative Declaration for the West Dublin BART Specific Plan and those policies and programs contained in the West Dublin BART Specific Plan approved by the City of Dublin. I Planning Commission Action: I The Planning Commission, at its meeting of February 10, 2004, considered the Addendum to the! SEIR and Negative Declaration, the West Dublin BART Specific Plan Amendment, the rezoning to a Planned Development Zoning District, and the related Stage 1 Development Plan. The Planning Commissidn was informed of the Applicant's request for an Inclusionary Zoning waiver and the fact that the City C~uncil would be acting on the request at a public hearing. I The Planning Commission discussed items such as parking, future project review, and timing ~f the development. The Planning Commission approved a change to the Stage I Development Plan kvhich I I ! ~Db' i would pennit any use as listed in the Commercial B category of the Specific Plan to occupy the s~arate 7,500 square foot building and to not limit the occupant to restaurant or retail uses as originally sugg~sted. The Planning Commission unanimously recommended to the City Council adoption of the AddeUdu!n and certification that it reviewed and considered the information contained in the SEIR, adoption of the West Dublin BART Specific Plan amendments, and rezoning the property to a Planned Development ~oning District, and approving the related Stage 1 Development Plan. i I I I This application has been reviewed by the applicable City departments and agencies, and their comjrnents have been incorporated into the Stage 1 Development Plan. The proposed project is consistent with the Dublin General Plan, West Dublin BART Specific Plan (with the approved amendments), and rep~esents an appropriate project for the site. i i I ! ! Staff recommends that the City Council (1) Open Public Hearing, (2) Receive Staff presentatiJn, (3) Receive Public Testimony, (4) Close Public Hearing, (5) Deliberate, (6) Adopt Resolution adopting an Addendum to both the Negative Declaration for the Downtown Specific Plan and the Supplementfl EIR for the West Dublin/ Pleasanton BART Station and Transit Village Project and certify that it review~d and considered the information contained in the EIR and Negative Declaration, (7) Waive Readin!g and introduce Ordinance adopting a West Dublin BART Specific Plan amendment, approving the rezoJing of property at 6600 Golden Gate Drive to a Planned Development Zoning District, and approving the related Stage 1 Development Plan, and (8) Adopt Resolution approving a waiver to the Inclusionary Zoning Ordinance per Section 8.68.040.E.

I On February 8, 1990, the BART Board of Directors approved the extension of the BART transpo~ation system to Dublin and Pleasanton. Along with approval of the Dublin/Pleasanton extension, I they certified an Environmental Impact Report that evaluated the environmental impacts associated I with extending the BART rail line through the Livermore/Amador Valley area into the communities ofqastro Valley, Dublin, Pleasanton, and Livermore. I In 2001, the BART Board of Directors approved a plan to construct the West Dublin/Pleasanton JART Station and the joint development of BART-owned pieces of property in Dublin and Pleasanto*. In approving the plan, BART, as the lead agency, certified a Supplemental EIR for the IWest Dublin/Pleasanton BART Station and Transit Village Project on April 2, 2001. BART is thd lead agency for this project, and the City is a responsible agency under CEQA. As a responsible agenc~, the City's role is very limited. Rather than certify Lead Agency's document as adequate, the dectsion- making body of a responsible agency is required only to certify that it reviewed and considered the information contained in the EIR prepared by the Lead Agency. (See Guidelines, S 15050, subd. (b)l) This project is within the boundaries of the West Dublin BART Spec~fic Plan area. The specifiJ Plan was adopted on December 19,2000 and is intended to guide future development in the area. A Ne~ative Declaration was also adopted on the same date that provided an environmental analysis for the !three downtown specific plans together. For the subject site, the West Dublin BART Specific Plan envistoned the development of a 240-room hotel and 160 high-density residential units, and the Ne4ative Declaration examined the potential impacts of such a project. i However, the development that is now proposed to take place on the Dublin parcel is slightly difrerent than the project that was analyzed in the Supplemental EIR and Negative Declaration. The overal land use development plan is still oriented toward creating a Transit Village providing an integrati. n of transportation services, employment opportunities, services and housing within a section of dowrltown I Dublin that is both visible and accessible from the freeways. The differences between the pre!vious project and the current proposal are summarized in the section below. I In order to determine if there were any en~ronmental impacts that were present with the revised ptoject proposal that were not already addressed (and mitigated if necessary) in the Supplemental Em.. and Negative Declaration, an Initial Study was completed. The Initial Study, dated January 12, f004, determined that the potentially significant effects of the project were adequately addressed ih the Supplemental EIR and Negative Declaration. This Addendum to the Supplemental EIR and Ne~ative Declaration has been prepared which notes the minor land use changes and their relation to the ce1ified Supplemental EIR ana Negative Declaration analysis. ! I EXl:lI Sill: ,. I I I PROJECT PROPOSAL: f The Planned Development Zoning District/Stage I Development Plan varies slightly from the projkt as originally proposed and analyzed in the two environmental documents:!

I A supplementary traffic analysis was completed to ensure that the traffic generated by the revised ptoject (150-room hotel, 210 apartment units, and 7,500 square foot restaurant/retail space) would nbt be substantially different than the project as studied in the Supplemental EIR and Negative Declatation (240-room hotel and 160 apartment units). I Since the trip generation rate for a quality restaurant is higher than the trip generation rate for a !retail space of the same size, the traffic analysis assumed the more traffic-intensive ("worst case") scenafio of having the 7,500 square foot pad utilized as a restaurant. I The results of the traffic analysis were as follows: Previous plans: 240-room full service hotel, 160 unit apartment complex Daily A.M. Peak Hour P.M.

I ! I ! Iw SEIR for the original project would also be sufficient to mitigate the traffic-related impacts of the re~ised . I project. i I CONCLUSION: I I Pursuant to Sections 15162 and 15164 of the California Environmental Quality Act (CEQA) Guide~nes, no subsequent EIR shall be prepared for this project, as no substantial changes have been proposed ~o the project which require revisions of the previous EIR. No new significant environmental impacts ha~e been identified and no substantial increase in the severity of previously identified impacts have bee~ discovered. I I I With minor technical amendments and clarifications as outlined in this Addendum, the Supplerriental EIR for the West Dublin/Pleasanton BART Station and Transit Village Project and Negative Dec1rnfation for the Downtown Specific Plans will continue to adequately address the environmental impacts ~f the proposed BART development on the Dublin parcel. 1 I This addendum will serve to document the file as such.

I Environmental Checklist/Initial Study Project Applicant Robert Russell Ampelon Development Group LLC 2101 Webster Street, Suite 1605 Oakland, CA 94612 i I Project Location and Context I The project site is located at 6600 Golden Gate Drive near Downtown Dublin. The site is approximatdly 7.26 acres and lies adjacent to the future West Dublin/Pleasanton Bay Area Rapid Transit District (BART) Station, on property currently owned by BART. The West Dublin/Pleasanton BART Station (not a part bf this project) will be built on an elevated structure in the median of the 1-580 freeway. Pedestri~n overcrossings will connect the main platform areas to parking garages in the cities of Dublin a~d Pleasanton. i I Exhibit 1 depicts the location of the project area in context of the larger City of Dublin, and Exhibit 2 depic~s the project site in relation to the West Dublin BART Specific Plan. : The projecl sile is loealed within !he Wesl Dublin BART Specific Plan area. This specific plan was adOPtld I by the City of Dublin on December 19, 2000 for the purpose of directing the land use, circulatioh, infrastructure and development for land located in the central portion of Dublin, west of the 1-680 freew~y and north of the 1-580 freeway. At build-out over the next five to seven years, the West Dublin BART Specific Plan area will allow the development of a range of residential, commercial office, ret~il, employment and public/quasi-public uses. i Contact Person for Initial Study Kristi Bascom, Associate Planner City of Dublin 1 00 Civic Plaza Dublin, CA 94568 Project Background and Description On February 8, 1990, the BART Board of Directors approved the extension of the BART transportation system to Dublin and Pleasanton. Along with approval of the Dublin/Pleasanton extension, they certifi~d an Environmental Impact Report that evaluated the environmental impacts associated with extending tne BART rail line through the Livermore/Amador Valley area into the communities of Castro Valley, Dublir, Pleasanton, and Livermore. A component of the Dublin/Pleasanton Extension EIR included an evaluatidn of the environmental impacts associated with the construction of the West Dublin BART station and jOirt development on parcels adjacent to the station. I In 2001, the BART Board of Directors approved a plan to construct the West Dublin/Pleasanton BA~T Station and the joint development of a BART-owned piece of property in Dublin for a 240-room hotel a~d 160-unit high-density residential units. In approving the plan, BART, as the lead agency, certified I a I City of Dublin PagEf3 Initial Study for the West Dublin BART Transit Village Project (PA 03-033) January 12, 2064 ! 10 Supplemental EIR for the West DublinlPleasanton BART Station and Transit Village Project on April I , 2001. BART is the lead agency for this project, and the City is a responsible agency under CEQA. As, a responsible agency, the City's role is very limited. Rather than certify Lead Agency's document ~s adequate, the decision-making body of a responsible agency is required only to certify thatit reviewed a~d considered the information contained in the EIR prepared by the Lead Agency. {See Guidelines, 9 1505b, I subd. (b).) ! This project is within the boundaries of the West Dublin BART Specific Plan area. The Specific Plan w~s adopted on December 1"9, 2000 and is intended to guide future development in the area. A Negati~e Declaration was also adopted on the same date that provided an environmental analysis for the thr$e downtown specific plans together. For the subject site, the West Dublin BART Specific Plan envisioned the development of a 240-room hotel and 160 high-density residential units, and the Negative Declarati~n examined the potential impacts of such a project. I However, the development that is proposed to take place on the Dublin parcel is slightly different than t~e project that was analyzed in the Supplemental EIR. The overall land use development plan is still oriented toward creating a Transit Village providing an integration of transportation services, employmert opportunities, services and housing within a section of downtown Dublin that is both visible and accessiole I from the freeways. The future West Dublin/Pleasanton BART station and the development proposed by the plan could be the catalyst for revitalization of the downtown area. The preliminary development pl~n for the Planned Development Zoning DistricUStage 1 rezoning indicates that the project sponsor proposes I a maximum number of 210 multi-family dwelling units (apartments) on 3.65 +1- acres of the 7.26-acre property, with a density of approximately 58 dwelling units per acre. A 150-room hotel is proposed for 2.43 +1- acres of property immediately northwest and adjacent to the future BART station. Instead of having t~e restaurant located inside the hotel as originally envisioned, a 7,500 square foot restaurant/retail lis proposed for 1.16 +1- acres of property immediately north of and adjacent to the future BART station. I The differences between the previous project and the current proposal are summarized below: Hotel I residential project Hotel I residential project as DifferencE described in 2001 SEIR currently proDosed Hotel size (rooms) 240 room full-service hotel with 150 room hotel -90 rooms restaurant, meeting rooms Residential units 160 apartment units 210 apartment units +50 units Restaurant/retail Included in full-service hotel Separate 7,500 square foot None I I I restaurant/retail pad I Since the existing Specific Plan, the Negative Declaration for the Specific Plan, and the We~t DublinlPleasanton BART Station and Transit Village Project Supplemental EIR analyzed a slightly differe~t mix of land uses on the property than are currently proposed, this Initial Study has been prepared to examine whether the alternative uses have an environmental impact that was not addressed and mitigat$d in the Supplemental EIR. i This Initial Study examines the potential environmental impacts resulting from development on the Dubljin parcel only, not the BART stalion itseW or the BART parking garage. i_ City of Dublin Page 4 Initial Study for the West Dublin BART Transit Village Project (P A 03-033) January 12, 20b4 I i } I The proposed project involves adopting a Planned Development Zoning DistricUStage 1 Development Plan for the Dublin property. With approval of the West Dublin BART Specific Plan in December 2000, the City of Dublin approved a General Plan Amendment to change the land use designation on the subject property to Retail/Office for 3.7+ acres and High Density Residential (30 to 50 dwelling units per acre) for 3.5+ acres, to accommodate the future use of the land for a commercial type use and multi-family housing. At that time, a Negative De.claration for the Specific Plan and the accompanying General Plan Amendment was also approved which analyzed and evaluated the land use mix proposed in the Plan. This Initial Study has reviewed the current proposal in light of existing environmental documentation to ensure that all impacts related to the proposed project are adequately addressed in the Supplemental EIR, mitigated to a less-than-significant level by measures incorporated in the project, and that no further environmental analysis is necessary for the project. This Initial Study has determined that the potentially significant effects of the project were adequately addressed in the Supplemental EIR and an Addendum to the Supplemental EIR has been prepared which notes the minor land use changes and their insignificant impacts. Future actions There is a Stage I Planned Development Zoning District designation on the property currently. Because the proposed project varies slightly from the existing Stage I Development Plan, a revised Planned Development Zoning District and Stage I Development Plan needs to be adopted to allow the project as proposed. Following approval of the Stage I Development Plan and West Dublin BART Specific Plan Amendment, it is anticipated that a Stage 2 Development Plan, Tentative Parcel Map, Site Development Review application, and possibly a Development Agreement would be submitted with the details on how the site and buildings will be designed and the maximum densities accomplished. As a part of the next phase of land use entitlements, grading activities would occur to accommodate planned land uses, roads and utilities. Water, sewer and recycled water services will be provided to the site by Dublin San Ramon Services District (DSRSD) in accord with DSRSD's Water Supply and Wastewater Collection System Master Plans. At the present time, it is anticipated that water supply for the project would be provided by Zone 7 of the Alameda County Flood Control and Water Conservation District. Water service is available to the surrounding properties and would be extended to serve this sit~. Sewer service for the project would be accommodated through connection to the existing sewer system owned and maintained by the Dublin San Ramon Services District (DSRSD), which has existing lines in the vicinity of the site and adequate capacity to service the planned development. When and where available, recycled water from DSRSD would be used for irrigation purposes, reducing the need for potable water. The storm drain system for the development will be connected to the existing system of drainage facilities owned and maintained by Zone 7 of the Alameda County Flood Control and Water Conservation System. This system consists of underground pipes, box culverts and open channels that flow southerly adjacent to 1-580. From there, stormwater runoff will be transported south into Alameda County Flood Control District facilities.

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 mitigation measures and briefly explain how they reduce the effect to a less than significant level.

Earlier Analyses Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or negative declaration. Reference Section 15063 (c)(3)(d). a) Earlier analyses used. Identify earlier analyses and state where they are available for review. Nearly all of the environmental setting, project impacts and mitigation measures for this Initial Study refer to environmental information and mitigation measures contained in the Supplemental Environmental Impact Report for the West Dublin/Pleasanton BART Station and Transit Village Project (Certified April 2, 2001) and the Negative Declaration prepared for the Downtown Specific Plans (adopted December 19, 2000). BART, as the lead agency for the West Dublin/Pleasanton BART Station and Transit Village project, prepared and certified a Supplemental EIR for the West Dublin/Pleasanton BART Station and Tran~it Village Project. BART is the lead agency on the project and the environmental review, and the City is a responsible agency under CEQA. As a responsible agency, the City's role is very limited. Rather than certify Lead Agency's document as adequate, the decision-making body of a responsible agency is required only to certify that it reviewed and considered the information contained in the EIR prepared by the Lead Agency. (See Guidelines, S 15050, subd. (b).) If the City were to conclude that the document .is inadequate under CEQA, its only remedy would be to litigate the EIR's adequacy. In order to satisfy the City's responsibilities as responsible agency under CEQA, Staff prepared this Initial Study for the project that analyzed the potential impacts of the project and the adequacy and suitability of BART's analysis, keeping in mind that the project as proposed is slightly different than the project analyzed in the SEIR and could have different or additional impacts. The Initial Study has determined that the potentially significant effects of the project were adequately addressed in both the Supplemental EIR and Negative Declaration. As part of the certification of the EIR, the BART Board of Supervisors adopted a Statement of Overriding Considerations for the construction noise and operational noise impacts. The certified EIR contains a large number of mitigation measures that will be applied to the West Dublin/Pleasanton BART Station and Transit Village Project. Specific mitigation measures are noted in the following discussion section. This Initial Study has been prepared due to the availability of more specific information on the Dublin project since the time of the SEIR certification, to document the environmental information related to the discretionary decisions to be made by the City of Dublin for the Transit Village project, and to analyze the current project details in relation to the previous project proposal. Copies of documents referenced here are available for public review at the City of Dublin Planning Department, 100 Civic Plaza, Dublin CA, during normal business hours. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 21 January 12, 2004 dB Discussion of Checklist I. Aesthetics Proiect Impacts and Mitiqation Measures a-d) Significant impact on scenic vista, damage to scenic resource, degrades visual character of the site or create light or glare? Construction of the proposed project would change the character of the area from undeveloped property within a predominantly light industrial area to an urbanized area with hotel and residential development, although a substantial amount of landscapin.g and pedestrian-oriented open spaces are anticipated to be included in the project. However, this site area is contained in the downtown urbanized portion of the City, and the introduction of the BART Transit Village development would entail construction of a multi-story hotel (five stories), a residential complex (four stories) and associated parking, and a restaurant/retail on land that .is currently undeveloped. Aesthetic impacts of constructing the project were addressed in both the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the Initial Study/Negative Declaration for the West Dublin BART Specific Plan. However, this development should not obstruct views of surrounding hillsides and would be considered consistent with t~e commercial character of the area. As this is a less-than-significant effect, no mitigation measures are necessary. However, the design of the project must be consistent with the Design Guidelines incorporated in the West Dublin BART Specific Plan, as a well-designed transit village would be an aesthetic asset to the Dublin downtown. The proposed plaza adjacent to the hotel and station, and the many pedestrian walkways and streetscape features of the Transit Village will further enhance the appearance and overall design of the project. As the adjacent 1-580 corridor is designated a Scenic Highway in the Dublin General Plan, the project must follow the City's guiding policy related to implementing a physical design that enhances a positive image of Dublin as seen by travelers on the highway. A more in-depth review and evaluation of the design of the structures and the pedestrian connections will be performed at Stage 2 of the Planned Development and Site Plan Review process. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the NegativeDeclaration for the Downtown Specific Plans. II. Agricultural Resources Proiect Impacts and Mitiqation Measures a-c) Converl Prime Farmland, conflict with agricultural zoning or converl prime farmland to a non- agricultural use? The site has not been used for agricultural purposes in the past or present, and no Williamson Act Land Conservation Agreement exists on the project site. It is located in an urbaniz~d portion of the City, completely isolated from other agricultural resources within the region. Additionally, the site is not located on Prime Farmland, Unique Farmland or Farmland of Statewide Importance as identified by the Farmland Mapping and Monitoring Program of the California City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 22 January 12, 2004 :i1 Resources Agency. The potential for impacts related to agricultural resources has been adequately assessed in previous environmental documents. Therefore, no adverse impacts to agricultural resources would result from the project and no additional mitigation measures are required. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. III. Air Quality Proiect Impacts and Mitiqation Measures a) Would the project conflict or obstruct implementation of an air quality plan? The proposed project would not conflict with the local Clean Air Plan adopted by the Bay Area Air Quality Management District, since the proposed number of dwelling units in the entire specific plans area is only slightly higher than what has been included in Dublin's planned growth as part of the West Dublin BART Specific Plan and is permitted under the City's General Plan. Additionally, the proposed land uses are consistent with the ABAG growth projections for the City of Dublin, and the proposed transit facility development has been included in the Transportation Improvement Plan for the nine-county San Francisco Bay Area. As a result, development of the proposed project would not conflict with the projections contained in the Bay Area '97 Clean Air Plan. Therefore, such impacts would be less- than-significant. b) Would the project violate any air quality standards? Short-term construction impacts related to implementation of the project, including grading and excavation, could result in exceeding air quality standards established by the Bay Area Air Quality Management District (West Dublin EIR, Impact 4.4-1). Adherence to the mitigation measures in Mitigation Measure 4.4-1 contained in the We$t Dublin/Pleasanton BART Station and Transit Village Supplemental EIR will reduce short-term t;lir quality impacts to a less-than-significant level. These measures minimize the creation of fugitive dust during grading and construction activities and also mandate that construction equipment be kept in proper running order. The West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR concludes that potential air quality impacts related to construction could be mitigated to a less- than-significant impact his impact. Similarly, potential air quality impacts related to vehicular traffic emissions on roadways and in the proposed parking structure of Reactive Organic Gasses and Nitrogen Oxide, both precursor indicators of smog, and stationary source emissions would not exceed regional air quality standards or thresholds. Additionally, approval of the proposed project would facilitate construction of the approved West Dublin/Pleasanton BART Station, which would substantially reduce automobile travel on the local and regional roadways by providing a transportation alternative for commuters. The result would be a net reduction in regional emissions. Therefore, this impact would be considered less-than-significant. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 23 January 12, 2004 Jf) c) Would the project result in cumulatively considerable air pollutants? The West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR identify vehicular emissions and stationary source emissions as less-than-significant impacts. Generally such impacts are based on vehicular emission from future traffic within the sub-region as well as stationary sources. As discussed in lI.b. above, approval of the project would allow development of an additional BART transit facility and also development of housing, office and commercial land uses near the transit facility. The result would be a net reduction in cumulative regional emissions. Therefore, this impact would be considered less-than-significant. d,e) Expose sensitive receptors to significant pollutant concentrations or create objectionable odors? The land uses proposed for site include residential and commercial land uses. As the development of the BART transit facility would actually reduce cumulative regional emissions and reduce the number Of vehicles on the area roadways, the project will not expose sensitive receptors to significant pollutant concentrations or create objectionable odors. No impact will occur and no further analysis is necessary . In sum, air quality impacts associated with the project have been addressed in previous environmental documents. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. IV. Biological Resources Proiect Impacts and Mitiqation Measures a) Have a substantial adverse impact on special-status species riparian features, movement of fish or wildlife species or conflict with Habitat Conservation Plan? Potential impacts to rare, threatened or endangered species have been addressed in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and Negative Declaration for the West Dublin BART Specific Plan Area as well as in the original EIR for the BART extension project. The development of the project site would result in the loss of approximately 9.5 acres of grassland habitat. All biological habitat was assumed to be removed from the site in original EIR for the BART extension project, and no increase in biological resources on the site has occurred. Because of the geographic location of the site between the 1-580 freeway corridor and light industrial/commercial development, it is highly unlikely that any special status species would locate on the site or use the site as mitigation or movement corridor. Additionally, a recent review of the California Department of Fish and Game's CNDDB conducted .in February 2000, and a site reconnaissance survey on March 16, 2000, confirmed that the biological resources existing on the site have not significantly .changed since the original EIR for the BART extension project was prepared. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 24 January 12, 2004 - -~._------_. >,j ~\ With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. V. Cultural Resources Proiect Impacts and Mitioation Measures a-d) Cause substantial adverse change to significant historic, archeological or paleontological resources or human remains? The West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the original EIR for the BART extension project identified no known historic or cultural resources on the project site. However, disturbance of unknown cultural resources, including disruption or destruction of prehistoric resources, and disruption to historic resources, may occur with the removal of vegetation and surface soils through development related grading activities. To reduce the potential degradation of unidentified cultural resources on the site, Mitigation Measures 4.10-2 have been included in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR to reduce impacts to cultural resources to a level of less-than-significant. ' With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. VI. Geology and Soils Proiect Impacts and Mitiqation Measures a-e) Expose people or structures to potential substantial adverse impacts, including loss, injury or death related to ground rupture, seismic ground shaking, ground failure, or landslide, substantial erosion, unstable soils or liquefaction? The West Dublin/Pleasanton BART Station and Transit Village EIR and the original EIR for the BART extension project identify several potential impacts to soils and geology, including earthquake, .ground shaking, and ground rupture. The site is relatively flat and contains no areas of slope, and no impacts related to landslides or erosion have been identified. Mitigation measures such as additional subsurface investigations, and with appropriate structural and foundation design incorporated into the final engineered design are contained in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the original EIR for the BART extension project, will reduce soils and geologic impacts to a level of less-than-significant. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 25 January 12, 2004 3d- Soils and geologic impacts associated with the project site have been addressed in previous environmental documents, including the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the original EIR for the BART extension project. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no addition'al mitigation measures are required. VII. Hazards and Hazardous Materials Proiect Impacts and Mitiqation Measures a-g) Create a significant hazard through transport of hazardous materials or release or emission pf hazardous materials, listed as a hazardous materials site, interference with an emergency evacuation plan, subject to wildland fires, or located near a public or private airstrip? No hazards related to transport of hazardous materials should occur with the development of the project as the BART station will serve only human passengers, and the other proposed uses are residential, a commercial hotel, and a restaurant/retail, none of which are associated with the transport or use of hazardous materials. The area has had reports of hazardous materials contamination, and development of the site could expose workers and sensitive receptors to hazardous materials in the area. Residents and hotel occupants would also be exposed to soil contaminants, both identified and unidentified, in the vicinity. A Phase 1 and Phase 2 Site Assessment was performed on the site for the original BART extension project and discussed in the West Dublin/Pleasanton BART Statiqn and Transit Village Supplemental EIR and the original EIR for the BART extension project. In order to determine the extent of soil and groundwater contamination on the site, the environmental documents recommend further field sampling prior to commencement of construction activities. If contaminants are identified, a remediation plan will be prepared consistent with applicable local, state and federal regulations. Adherence to Mitigation Measure 4.7-1 contained in the West Dublin/Pleasanton BART Station a~d Transit Village Supplemental EIR and the original EIR for the BART extension project will reduce potential risks related to hazardous materials exposure and contaminants to a less-than-significant level. The site is not in an area subject to wildland fires, and lies outside the referral area for the Livermore Municipal Airport. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 26 January 12, 2004 33 village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. VIII. Hydrology and Water Quality Proiect Impacts and Mitiqation a-i) Violate any water quality standards or waste discharge requirements, deplete groundwater resources, alter drainage patterns, effect surface or subsurface water quality, result in placing housing in a flood plain? Water and hydrologic impacts of the proposed development of the Transit Village project were addressed in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the original EIR for the BART extension project, certified by the BART Board of Supervisors in 1990 and 2001. Impacts reviewed included potential flooding, loss of groundwater recharge area, potential increases in surface water quality pollution. Since the proposed project will develop the same area on the site as assumed in the original EIR for the BART extension project, no new significant stormwater drainage impacts are anticipated. Construction activities and operational site uses associated with the project could result in degradation of water quality in nearby surface water and reservoirs by reducing the quality of stormwater runoff. A Notice of Intent (NOI) must be filed with the Regional Water Quality Control Board (RWQCB) and a Stormwater Pollution Prevention Plan (SWPPP) will be developed and implemented for the site, in accordance with the mitigation measures discussed in the Supplemental EIR. Adherence to mitigation measure 4.2-2 will reduce potential impacts to water and water quality to a level of less-than-significant. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restauranUretail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. IX. Land Use and Planning Proiect Impacts and Mitiqation a) Physically divide an established community? The project iS,vacant and has been planned for similar uses associated with a BART Station since the original adoption of the Dublin General Plan in 1990. The adoption of the West Dublin BART Specific Plan and related General Plan Amendment to change the land use designation on the subject property to Retail/Office for 3.7+ acres and High Density Residential (30 to 50 dwelling units per acre) for 3.5+ acres, to accommodate the future use of the land for a commercial type use and multi-family housing. At that time, a Negative Declaration for the Specific Plan and the General Plan Amendment were also approved which analyzed and evaluated the land use mix proposed in the Plan, including that proposed in the area of the future West Dublin BART Transit Village proposed at that time by Jones Lang LaSalle Project and Development. Management. Surrounding uses planned for the area under the Specific Plan are mixed use (combination of residential and retail/commercial or office uses) and retail/commercial and City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 27 January 12, 2004 ---I.:, .- 3~ office type uses. Adjacent to the southern property boundary is the 1-580 freeway corridor. Therefore, there would be no disruption of any established community. b) Conflict with any applicable land use plan, policy or regulation? The proposed project would be consistent with goals and policies contained in the Dublin General Plan. The project as proposed is a higher residential land use density than is currently allowed in the West Dublin BART Specific Plan. The project is requesting a Specific Plan amendment to allow 58 units per acre on the High Density Residential site instead of the maximum 45 units/acre that is currently allowed. Although this density sounds like a sizable increase, the overall increase in the number of residential units .in the Specific Plan area is not very much because the overall number of residential units proposed in the whole West Dublin BART Specific Plan area is increased only slightly, as shown on the table below. Additionally, the number of accompanying hotel rooms has been reduced from 240 rooms to 150. Subject site Other residential site in Total 6600 Golden Gate the W. Dublin BART Dr Specific Plan area: 6700 Golden Gate Dr Units allowed per Specific Plan 160 331 491 Units proposed in actual projects 210 304 514 Unit surplus (deficit) 60 (27) 23 This project consists of a rezoning to implement the existing general plan designations on the site and a request to amend the Specific Plan to allow the increased density. No impacts are anticipated as a result of this request and no additional mitigation measures are required. c) Conflict with a habitat conservation plan or natural community conservation plan? No such plan has been adopted within the West Dublin BART Specific Plan area, in which the Transit Village project is located. There would therefore be no impact to a habitat conservation plan or natural community conservation plan for the proposed project. . With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no addition.al mitigation measures are required. x. Mineral Resources Proiect Impacts and Mitiqation a, b) Result in the loss of availability of regionally or locally significant mineral resources? The site is not located in an area of aggregate resources. The West Dublin/Pleasanton BART Station and Tran~it Village Supplemental EIR and the original EIR for the BART extension project do not indicate that significant deposits of minerals exist on the site. Therefore, no impacts would occur. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 28 January 12, 2004 ?P With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no addition'al mitigation measures are required. XI. Noise Proiect Impacts and Mitiqation a-D Would the project expose persons or generation of noise levels in excess of standards established by the General Plan or other applicable standard, expose people to groundborne vibration, result in permanent increases in ambient noise levels? The West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR addressed potential noise impacts of implementing the proposed Transit Village project. Noise related impacts identified in the EIR included exposure of future residents in the residential portion of the development and occupants of the hotel to increased levels of noise due to the proximity of the 1-580 freeway corridor, and exposure of residents and occupants to construction noise from the BART Station and parking structure to be constructed on adjacent sites. Mitigation measures 4.3-1 through 4.3-4 outlined in the Supplemental EIR will mitigate most noise impacts to a level of less-than-significant. However, the impacts of noise generated by the 1-580 freeway corridor on exterior noise levels in outdoor areas of the project was identified as an impact that may remain significant even after mitigation and a Statement of Overriding Considerations was adopted. Additionally, on-site construction activities that occur after the residential units and tbe hotel are occupied could exceed acceptable ambient noise levels above the significance thresholds, even with the implementation of proposed mitigation measures. This impact was also identified as significant and unavoidable, with no additional or feasible mitigation available to reduce it to a less- than-significant level, and a Statement of Overriding Considerations was adopted. To mitigate interior noise levels to an acceptable level for the residences and the hotel, the project developers will be required to commission an independent acoustical consultant to develop noise attenuation measures to be incorporated into the design and construction of the proposed residential and hotel components of the project (Charles Salter and Associates, 1997). Adherence to site- specific mitigation measures contained in the acoustical analysis and all other mitigation measures set forth in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR will reduce noise impacts to a less-than-significant level. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no addition'al mitigation measures are required. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 29 January 12, 2004 XII. Population and Housing Proiect Impacts and Mitiqation 3LP a) Induce substantial population growth in an area, either directly or indirectly? Approval of the proposed Transit Village rezoning is substantially consistent with the existing, approved West Dublin BART Specific Plan and the Dublin General Plan for the site. The project would add an addition.al 210 multi-family housing units to the City's housing units, and introduce residential development to an area of predominantly retail/commercial and office development. However, this is consistent with the intent and land use designations in the Specific Plan and the General Plan, and is considered an appropriate land use given the location of the future West Dublin BART station and the regional need to develop housing in proximity to transit facilities. No impacts are therefore anticipated, and no mitigation measures are required. b) Would the project displace substantial numbers of existing housing units or people? The site is vacant, and no housing exists on the site. Implementation of the proposed project would therefore displace neither housing units nor people. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restaurant/retail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. XIII. Public Services Proiect Impacts and Mitiqation a-e) Potential impacts related to: fire protection, police protection, schools, maintenance, or solid waste generation? The West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the original EIR for the extension project identify a number of potential impacts associated with the approval and construction of the BART Station and Transit Village project. These include a slight increased demand for police and fire service, police service accessibility, fire response to the project area, minor financial impacts to local school districts, increased solid waste generation, and impacts to solid waste facilities, but not to a substantial or significant level. BART would provide police protection services for facilities related to the BART station and parking garage, which are primarily associated with auto thefts and burglaries with the station parking areas. In accordance with City of Dublin regulations and policies, the project sponsor will be required to pay a negotiated fire impact fee to offset fire protection service costs incurred as a result of project implementation. Additionally, school and park impact fees will be required to cover any additional service costs. Adherence to these mitigation measures will reduce public service impacts to a less- than-significant level. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 30 January 12, 2004 31 Potential public service impacts associated with the Transit Village project have, therefore, been addressed in previous environmental documents, including the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and Negative Declaration for the West Dublin BART Specific Plan. The proposed rezoning of the site is consistent with previous actions and environmental documentation approved by the City of Dublin and no additional mitigation measures are required. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restauranUretail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no additional mitigation measures are required. XIV. Recreation Proiect Impacts and Mitiaation a, b) Would the project increase the use of existing neighborhood or regional parks or require the construction, of new recreational facilities? Parks and recreation impacts of the project have been addressed in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR.A slight increased demand for park facilities is anticipated with the Transit Village project; however, itis not expected that future residents of the project would utilize the park facilities in the City such that substantial deterioration of the facilities would occur. In accordance with City of Dublin regulations and policies, the project sponsor will be required to pay park impact fees to cover any potential additional service costs related to the development. Potential parks and recreation impacts associated with the project have therefore been addressed .in previous environmental documents, including the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and Negative Declaration for the West Dublin BART Specific Plan, and no impact related to recreational services would result. The proposed rezoning and subdivision of the site is consistent with previous actions and environmental documentation approved by the City of Dublin and BART, and no mitigation measures are required. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restauranUretail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by the City of Dublin and no addition'al mitigation measures are required. xv. Transportation/Traffic Proiect Impacts and Mitiaation City of Dublin Initial Study for the West Dublin BART Transit Village. Project (PA 03-033) Page 31 January 12, 2004 3S a-g) Cause an ,increase in traffic which is substantial to existing traffic load and street capacity, exceed LOS standards for CMA roadways, change of air traffic patterns, increase traffic safety hazard, provide for inadequate emergency vehicle access, inadequate parking, provide hazard or barrier to alternative transportation modes? Traffic and transportation impacts associated with the approval and implementation of the West Dublin BART Station and Transit Village project have been addressed in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR, and the Negative Declaration approved by the City of Dublin for the West Dublin BART Specific Plan. Specific impacts identified in the Supplemental EIR included impacts resulting from cumulative traffic growth in the region, to which the proposed project would contribute. In the Existing Plus Approved Projects Plus Project Plus General Plan Buildout Scenario, the project would contribute to the unacceptable operation of the intersections of Dublin Boulevard/Golden Gate Drive, Dublin Boulevard/Amador Plaza Road, Dublin Boulevard/Dougherty Road, St. Patrick Way/Golden Gate Drive, and San Ramon Road/l-580 interchange. Additionally, cumulative traffic growth in the region with the project would contribute to traffic volumes on roadway segments of Amador Plaza Road south of Dublin Boulevard and Golden Gate Drive exceeding their capacity. A project-specific traffic impact analysis was prepared to analyze the impacts of the change in land use with the West Dublin BART Specific Plan and General Plan amendment action (Omni-Means, 2000). The Omni-Means report concluded that all traffic and circulation impacts of the proposed Specific Plan, which included implementation of the land uses proposed with this project, could be reduced to less-than-significant levels after a number of roadway improvements are completed in the vicinity of the project. Those improvements specifically relating to the development of the Transit Village project will be made conditions of the rezoning and parcel map approval. The West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR also sets forth a number of mitigation measures to assist in reducing cumulative traffic impacts related to the development of the BART Station and the Transit Village project. These include Mitigation Measures 6-1 through 6-2 of the EIR. In sum, potential traffic and transportation impacts associated with the project have been addressed in previous environmental documents, including the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR, and the Negative Declaration for the Downtown Specific Plans. Additional traffic analysis was done for the revised project proposal of 210 multi-family residential units, a 150-room hotel, and a 7,500 square foot restaurant/retail. The traffic study, conducted by T JKM, concluded that based on the increased number of residential units and decreased number 'of hotel rooms, there would actually be a reduction in the number of vehicle trips generated by the project. This analysis assumed that the hotel type remained full-service, which has a daily trip rate of 8.23 trips per room. If a different type of hotel, such as a limited-service hotel, were built instead, the traffic impacts would be less. An Addendum was prepared to the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR that explains the analysis and its results in greater detail. Once the additional traffic analysis was completed, it was determined that the proposed rezoning and subsequent subdivision is consistent with previous actions and environmental documentation and no additional mitigation measures are required. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 32 January 12, 2004 ~q XVI. Utilities and Service Systems Proiect Impacts and Mitiqation a-g) Exceed wastewater treatment requirements of the RWQCB, require new or expanded water or wastewater treatment facilities, require new storm drain facilities, require additional water supplies, require new or expanded wastewater treatment, facilities, or require new solid waste facilities? Potential impacts of the Transit Village project were addressed in the West Dublin/Pleasanton BART Station and Transit Village Supplemental EIR and the Negative Declaration for the West Dublin BART Specific Plan. Impacts addressed included impacts to the wastewater and wastewater treatment and disposal system, water system, over drafting of groundwater resources, additional water treatment plant capacity needs, inducement of substantial population growth as a result of an expanded water system, and need for additional water storage facilities. The environmen~al analyses concluded that the project would incrementally increase the need for these services, but to a less-than-significant level. Adequate resource supplies and utility services are available to the project site, and no mitigation measures are required. Some basic utility service fees, required of all construction within the City, may be required for connection. to systems and facilities. With the revised project proposal of 210 residential units, 150 hotel rooms, and a 7,500 square foot restauranUretail, there are no impacts beyond those that have already been identified (and mitigated if necessary) in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. The proposed development of the transit village project is consistent with previous actions approved by actions and environmental documentation approved by the City of Dublin and no additional mitigation measures are required. XVII. 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 with the implementation of mitigation measures included in the Final West Dublin/Pleasanton BART Station and Transit Village SEIR and the Negative Declaration for the Downtown Specific Plans. b) 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, the project site lies within an area with an approved specific plan and the impacts of the project were anticipated and mitigated. City of Dublin Initial Study for the West Dublin BART Transit Village Project (PA 03-033) Page 33 January 12, 2004 IjO c) Does the project have environmental effects which will cause substantial adverse effects on humf,ln beings, either directly or indirectly? No. No such impacts have been discovered in the course of ' preparing this Initial Study.

Pursuant to Section 8.32.070 of the Dublin Municipal Code, the City Council finds as follows. 1. The Planned Development Zoning District meets the purpose and intent of Chapter 8.32 in that it provides a comprehensive development plan that is sensitive to surrounding land uses by virtue of the layout and design of the site plan, and uses creative design and a mix of complementary uses to establish the project as a focal point for the area surrounding the future West Dublin/Pleasanton BART Station. 2. The Planned Development Zoning District will be harmonious and compatible with existing and future development in the surrounding area in that the residential, hotel, and commercial use of the site will be complimentary uses to the future transit West Dublin/Pleasanton BART Stat~on. The land uses and site plan provide an efficient use of the property and are compatible with the existing retail, office, and light industrial uses surrounding the property as well as to the more intensive land uses that will likely develop in the future. B. Pursuant to Sections 8.120.050.A and B of the Dublin Municipal Code, the City Council finds as follows. 1. The Site is a relatively flat, infill site, with existing infrastructure (including roads, sewer, storm drain, potable and recycled water, natural gas, and electricity) located immediately adjacent to the site and no major or unusual physical or topographic constraints and thus is physically suitable for the residential, hotel, and commercial proj ect proposed for the Planned Development Zoning District. 2. The Planned Development Zoning District will not adversely affect the health or safety of persons residing or working in the vicinity, or be detrimental to the public health, safety and welfare in that the project will comply with all applicable development regulations and standards and will implement all adopted mitigation measures. 3. The Planned Development Zoning District is consistent with the General Plan and West Dul?lin BART Specific Plan in that the project includes companion amendments to the West Dubli:q BART Specific Plan were approved by the City Council in Resolution XX-04 on March 2,2004, and which amendments proposed the land uses and development plans reflected in the proposed Planned Development Zoning District. / 'ATTACHMENT 2. t.fL- C.

No new significant environmental impacts have been identified and no substantial increase in the severity of previously identified impacts have been discovered; and i WHEREAS, the California Environmental Quality Act provides for an Addendum process when a minor change is proposed on a project where there is an approved EIR, Negative Declaration, or Mitigated Negative Declaration; and , , WHEREAS, an Addendum, dated January 12, 2004 and attached to this resolution as Exhib~t 1, was prepared which notes the minor land use changes and their relation to the analysis in the Supplemental EIR and Negative Declaration; and , WHEREAS, an Addendum to the Supplemental EIR and Negative Declaration has been prepared and will be considered by the Planning Commission together with the original Supplemental EIR and Negative Declaration. i NOW, THEREFORE, BE IT RESOLVED THAT the Planning Commission has revie'wed and considered, the Addendum dated January 12, 2004, together with the Supplemental EIR and Negative Declaration (both available and on file in the Planning Department), and finds that these documents ryflect the independent judgment of the Planning Commission and the City as a responsible agency in the CEQA process. The Dublin Planning Commission does hereby find that no new environmental impacts could occur a~ a result of the revised project proposal and therefore no new environmental documents have been prepared. I BE IT FURTHER RESOL VED THAT the Dublin Planning Commission does hereby find th4t: A. The proposed project is consistent with Dublin General Plan. B. The City has reviewed and considered all environmental documents that have been prepared regarding this proj ect. C. . The City finds that the development of the West Dublin/Pleasanton BART Transit Village I project will be harmonious and compatible with existing and future development in the surrounding area. BE IT FURTHER RESOLVED THAT the Planning Commission recommends that the City Council adopt an Addendum to both the Negative Declaration for the Downtown Specific Plans and the Supplemental . EIR for the West Dublin! Pleasanton BART Station and Transit Village Project and certify that it revi~wed and considered the information contained in the SEIR and the Negative Declaration for the hotel, residential, and small-scale commercial project proposed at 6600 Golden Gate Drive.

Jennings asked if a hazardous material permit is required. Mr. Saddeh responded yes. Cm. Nassar if there were any further questions, hearing none he closed the public hearing. Cm. King stated that the business owners that have come forward and have very valid concerns. The area is zoned for this type of business subject to a conditional use permit. He would like to vote for approval, however, with a condition for screening the fence and limited to certain type of repairs. Cm. Machtmes had concerns with the use type and how realistic it would be to have the us~ perrrritrevoked. I Cm. Jennings asked if there are similar uses in the surrounding area. Ms. Harbin stated Smart Auto Glass is in the area. Cm. Nassar suggested a modification to the conditions to specify the type of services allow~d, the fence" and possibly staff and the applicant to meet with those concerned. . After much discussion, the Planning Commission continued the item to March 9,2004. 8.3 P A 03-033 Stage 1 Planned Development Rezoning and West Dublin BART Specific Plan Amendment for a residential, hotel, and restaurant/retail development on property at 6600 Golden Gate Drive. Ampelon Development Group, on behalf of the San Francisco Bay Area Rapid Transit District (BART) has submitted an applicatioD for a Stage 1 Planned Development Rezone/Development Plan for a 210-unit apartmeht complex, ISO-room hotel, and 7,500 square foot ancillary restaurant/ retail pad at 6600 Golden Gate Drive. Cm. Nassar asked for the staff report. Kristi Bascom presented the staff report and explained that the proposed project consists of a West Dublin BART Specific Plan amendment, Planned Development Rezoning, and related Stage 1 Development Plan to permit 210 apartments, a 150-room hotel, and 7,500 square fOQt restaurant/retail pad on approximately 7.26 acres at 6600 Golden Gate Drive, adjacent to the future West Dublin BART station. The high-density residential portion of the development would be located on the southwest corner of St. Patrick Way and Golden Gate Drive, and is proposed as a four-story building wrapped around structured parking. The hotel portion of the project would be located clogest to Highway 580, and is proposed as a five-story hotel with surface parking and some parking Commission 12 ,'- .' ~Cf :J) , I within the future BART garage, which will be built on a separate parcel. The restaurant/ retail portion of the project would be located at the end of Golden Gate Drive, closest to the futur~ BART station pedestrian bridge entrance. The single-story building will share the same surface parking lot as the hotel, and could be developed as either a full-service quality restaurant or a retail establishment. At this time the Applicant is considering both possibilities. This flexibility can be preserved as long as total vehicle trips generated by the entire project is at or below that which has been studied and documented in the Initial Study and Addendum. The Applicant is requesting a waiver of the City's Inclusionary Zoning Regulations under Section 8.68.040.E, which states "The City Council, at its discretion, may waive, wholly or partially, the requirements of this ordinance and approve alternate methods of compliance with this chapter if the applicant demonstrates, and the City Council finds, that such alternate methods meet the purposes of this chapter." The Planning Commission does not take actio;n on the Inclusionary Zoning waiver request, and it will be reviewed by the City Council at a fu1;ure public hearing. The applicable City departments and agencies have reviewed this application, and their comments have been incorporated into the Stage 1 Development Plan. The propqsed project is consistent with the Dublin General Plan, West Dublin BART Specific Plan (with tl;le proposed amendments), and represents an appropriate project for the site. The Applicant for the project spoke gave a brief outline about the project. Cm. Machtmes.asked the Applicant's relationship to BART. The Applicant responded that'they are the Master Developer for the entire project. He further indicated that they were selectep through a competitive process and since then have been working with BART to get the Entitlement process completed through the cities. They.are currently working with the CitY of Dublin for Stage 1 PD and a PUD through the City of Pleasanton. They selected a design team and stated that they presented the preliminary concept of the station to the City Council. He also indicated that the preliminary design concept would be presented to the Planning Commission within the next month. They are currently in the process of selecting a design team for the BART Garage. , Cm. Machtmes stated that the reason for his question was to understand if the Applicant is in a position to talk about the best possible use surrounding the BART station. In other words, based on the surrounding uses of the other BART stations in the Bay Area, would the Restaurant/Retail use proposed for the site in Dublin an appropriate use. The Applicant stated that the Fruitvale Station in Oakland is a larger area and therefore a Residential/Retail mix;ed use was possible. The Pleasant Hill BART Station, he pointed out was not well connected. , Although there is an oasis of parking with surrounding uses being office and residence, it does not have any retail. The residents were opposed to retail uses due to traffic issues. The I Applicant pointed out that the proposed project is designed to give a Transit Village look and once implemented would be a welcome change to the existing conditions. This design was more successful in the Eastern Dublin area due to the availability of land. The current project site has a limited area, which has imposed restrictions on designing large-scale development on it. Y[,;rmi'l1iJ Cammission 13 1''tbrUMY fO, 2004 bO Cm. King wanted to know if the plan for the proposed projected included any open space dr park area in it. The Applicant pointed out that a pedestrian bridge from the station will en<;l in a . Plaza area connected to the garage which has been designed for landscaping in order create a pedestrian friendly environment. Hearing no other comments, Cm. Nassar closed the public hearing and opened it for discu~sion among the Commissioners. Cm. Machtmes voiced his concerns regarding the Restaurant/Retail use and if it constitute$ the highest and best use for a property intending to connect to a BART station. He understand~ the fact that the future improvements along the Golden Gate may enhance the surrounding us~s but he fails to see how the change of the current use from Hotel to Restaurant/Retail use would help achieve the intended goal. . Cm. King agreed with Cm. Machtmes' opinion and stated that a pedestrian friendly atmosphere near the BART station is always a welcome site. Cm. Machtmes asked when rezoned, would the use be obligatory or permitted. Ms. Bascom stated that the current land use designation for the site under the West Dublin. BART Specific Plan was Hotel/Lodging. The Applicant is requesting the rezone to Comm~rcial B to permit restaurant/retail uses in a separate 7500 sq. ft. building. If the Commission so desired to leave flexibility of uses then it could leave the designation open to allow any Commercial B uses as allowed by the West Dublin BART Specific Plan including specialty retail, restaurants offices, entertainment, and similar pedestrian-oriented uses, and not limit the 7(500 sq. ft. building to only restaurant or retail. Cm. Nassar opened the public hearing and asked the Applicant to clarify the concerns the Commission had. The Applicant stated that the uses being suggested by the Commission were discussed witp. Staff and based on those discussions and the impact a larger hotel would have on traffic w~re the reason why they decided to scale down the hotel and request a rezoning of a portion of the area to commercial uses. Hearing no other comments or questions, Cm. Nassar closed the public hearing. Cm. Machtmes suggested that the uses allowed on the Commercial B portion of the property should remain as described under the West Dublin BART Specific Plan. On a motion by Cm. King seconded by Cm. Machtmes by a vote 4-0-1 with Cm.

The fence is proposed to ring the development leaving a portion of the parking area adjacent to Dublin Boulevard outside of the fensed area and available for visitors. em. Nassar asked for the staff report. Mr. Porto presented the staff report. He stated that the Applicant, Sybase, is proposing to enclose their site with a fence. They would like to put a perimeter fence 6-feet in height around their property along the Hacienda frontage, Central frontage, along the common access with Site 15 A, along the common property line and along the front of the project. Additionally, they are proposing to put a 4-foot fence around the front of the property around the visitor's parking lot and another 4-foot fence which would be serpentine in nature along the front of the property along the Dublin Blvd frontage connecting from Building B to Building A. This particular fence would be in front of a visitor parking area, but the visitor parking would not be gated. The fence would be a wrought iron fence and would be grey in color to complement the existing structure. There are also Pilasters proposed in the project which would have lights with Sybase logo and additionally, the applicant is proposing to redesign two of the driveways to permit the ability for cars entering that area to exit in case they can't get access to the site. The Applicant's request for the fence is mainly because of security.

The analysis is intended to satisfy the requirements of the California Environmental Quality Act (CEQA), and provide the City with adequate information for project revie This initial study includes a project description, environmental checklist 8.0d discussion focus~d upo issues identified in the checklist. Modifications in the Specific Plans have been made since the oriqinal draft Neqative Declaration and Initial Study were circulated in September 2000. The revisions to the Plans are described in this revised document and have been evaluated on the basi of their related environmental im acts in this revised document. Because the modifications are min ' r in nature and result in no siqnificant impacts, recirculation of the Neaative Declaration and Initial Study is not required under CEQA Guidelines section 15073.5. Additions to the oriqinal document are shown with an underline, and deletions from the docllment are shown .vvit~a ctriko throuoh: In summary, this Initial Study concludes that the project will not pose any significant advers environmental impacts. With the policies and proqrams are included in the Specific Plans, no siqnificant impacts will result. .. . The Initial Study was prepared based upon the location of the project, planning staff review, field review, comments from City, County and local agencies, studies prepared by consultants, use of City Planning Documents, the CEQA Law and Guidelines, and City of Dublin CEQA Guidelines. PROJECT DESCRIPTION The proposed project consists of three specific plans developed for the downtown area of Dublin, trye r Downtown Core Specific Plan, the West Dublin BART Specific Plan, and the Village Parkway spec~lc , Plan to be considered for adoption by the Dublin City Council. The Specific Plans are intended to d.rect the use of land, the design of public improvements, and the design and appearance of private and ublic development; including buildings, parking areas, signs and landscaping. The adoptions of the PlanE will require General Plan Amendments for the Downtown Core and West Dublin BART Specific Plan arras related to land use changes and land use intensification. Additionally, the. portions of the previousl)' adopted (1987) Downtown Specific Plan will require repeal with adoption of the plans, to mOdifY, ser ions of the document relative to Zones 1,2,3,4,7,8,10 and 11. Following Plan adoption, amendment of t e City's Zoning Ordinance will be necessary. The Downtown Core Specific Plan area is generally located between 1-680 to the east and San Ra I on Road to the we?t, and Amador Valley Boulevard to the north and Dublin Boulevard to the south, and consists of approximately 51 acres of commercial land uses. The westerly boundary of the Plan ar~a is . the westerly property line of the parcels containing the existing Montgomery Wards and Target ret il stores. The Specific Plan calls for a maximum development potential of 1 ,206,848 1,100,110 squa, feet commercial, office and mixed-use development and approximately 148 dwellings. The oriqinal environmental initial stud evaluated a maximum develo ment otential of 1100 110 s uare feet f r the area. However since that time the Cit Council has discusse .', an alternative ~an to remove the' ih Dens' Residential land use for senior housin from the Plan arid maintain the retail commercial se on the Dublin Place sho in center site with an increa.se in FAR to .40. This chane if a roved ViI uld increase the s uare foota e of Commercial A retail US,e in the area bafoximatet 40 000 s blat feet. Additionally, an increased FAR of .79 was recommended to the City Council bvthEfPlanniriQ Commission for the ro ert owned b Dublin Honda on Amador Plaza Road, which couldincreas the potential buildout square footaqe of the 2.55acres of Retail/Auto use hi the Plan area bY 65.330 so are feet to 87.750 square feel [ The West Dublin BART Specific Plan area is generally located between 1-580 to the south and D~ Iln Boulevard to the north. San Ramon Road lies to the west of the area, and properties on the west s de of (Golden Gate Avenue are included in the plan area. The area consists of approximately 70 acres 0 . commercial, office and light industrial land uses. The Village Parkway Specific Plan area is generally located between the north and south sides of Amador Valley Road to the north and Dublin Boulev rd to ! the south. The 1-680 freeway forms the southwestern boundary of the area and lies adjacent to the rear property line of commercial uses. The area consists of approximately 31 acres of restaurants, offices, retail commercial, service commercial and other non-residential uses fronting on this portion of Village ....", Parkway.. A maximum development potential of 1,900.743 1,750,055 square feet of non-residential and 491 residential dwellings are anticipated at full Specific Plan buildout. The orioinal environmental initial study evaluated a maximum development potential of 1,750,055 square feet. However. since that time. the FAR for office uses shown on the Land Use Plan (Exhibit 9) of the Specific Plan has been increased from .87 to 1.00. to add approximately 40,000 square feet to the total amount of square footaqe in the area. The hotel proposed on the BART-owned property has also increased in square footaoe bv 109.864 square feet from the orioinal proposal evaluated in the document. increasino the FAR to 1.12 for that portion of the Plan. The impacts of these increases in square footaoe and FAR's are assessed In this revised study. The Village Parkway Specific Plan is generally sited along the east and west sides of Village Parkway between Dublin Boulevard to the south and Amador Valley Boulevard to the north. The Specific Plan area encompasses approximately 31 acres of land and has been developed with a mix of retail commercial, restaurant, office, automotive and similar uses, including the main Dublin Post Office. ' Existing types of land uses are anticipated to remain, however, a higher Floor Area Ratio included as part of the Specific Plan is intended to encourage intensification of uses with a more pedestrian-oriented design. Exhibit 3 shows the proposed land use concept for the Downtown Core Specific Plan; Exhibit 4 shows the land use concept for the West BART Specific Plan; and Exhibit 5 shows the land use concept for the Village Parkway Specific Plan. Two potential alternatives to the roadway desion for Villaqe Parkway are considered in this initial study. The Task Force for the Specific Plan reviewed several possible aliqnments. and recommended implementation of a roadway desiqn that would decrease the number of traffic lanes and add diaoonal parkinq within the existinq ri~ht-of-wav. Staff recommends maintaininq the roadway with four lanes of traffic and parallel parkinq as it currently exists. with. ' streetscaoe desiqn modifications. All alternatives considered are discussed in this document as are the Task Force recommended alternative and the Staff recommended desiqn.

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 involv, ed (e.g. th, e projet falls outside a fault rupture zone). A "no impact" answer should be explained where it is bas d on project-specific factors as well as general factors (e.g. the project will not expose se, sitive 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 pperational imp cts. 3) "Potentially Significant Impact" is appropriate if there is substantial evid~nce that an eff ct is significant. If there are one or more "potentially significant impact" entries when the determi ation is made, an EIR is required. .. i'NegatlveDeCfaratfOn:Pofentially Significant Unless Mitigation Incorporated" implies elsewhe e the incorporation of mitigation measures has reduced an effect from "potentially significant effec " to a "less than significant impact." The lead agency must describe the mitigation measures and riefly explain how they reduce the effect to a less than significant level. 5) Earli.er analyses may be used where, pursuant to the tiering, program EIR, or other EQA processes, an effect has been adequately analyzed in an earlier EIR or negative decla ation.

Land Use and Planning Environmental Settinq The project site area is the existing downtown commercial area of Dublin. The project site is the location of approximately 150 acres of retail shops, restaurants, commercial businesses, offices and light industrial uses with associated roadways and parking areas. Various small parcels remain undeveloped. No residential development has occurred within the project area. The City's existing General Plan and Zoning Ordinance envision a mix of retail, lodging, auto service, restaurant, office and similar uses within the project area. Proiect Impacts ~ a) Conflict with general plan designation and zoning? LS. The Dublin General Plan designates the downtown specific plan areas as Retail/Office, Retail/Office and Automotive, and Public/Semi-Public Facility, which allow retail uses, commercial service uses, and civic type uses. The City's Zoning Ordinance establishes C-1, Retail Commercial; C-2, General Commercial; C-N, Neighborhood Commercial; M-1, Light Industrial; and PD, Planned District zoning districts in the project area. Some land use designations in the Downtown Core and the West Dublin BART Specific Plan areas would be modified through the general plan amendment process in conjunction with adoption of the land use plans for these areas; however, the modifications would generally be minor and establish another commercial type land use compatible with the existing and surrounding .land lJses. In the West Dublin BART area, some high density residential use designations are proposed to replace Public/Semi-Public Facility and Retail/Office designations in close proximity to the BART station location. This change would be consistent with the intent of the existing General Plan to create a more transit-oriented area near the proposed BART station. The residential use would support the surrounding commercial development proposed, and also provide riders for the transit facility. The designation of Public/Semi-Public Facility was placed on a portion of the property in the area with the anticipation that the BART station would be developed in the general area. In the Downtown Core Specific Plan area, the intent of the Specific Plan is to retain existing major retailers (Target, Montgomery Ward and similar users), and, at the same time, add complementary smaller scale retail uses, restaurants, entertainment uses and offices to attract a more pedestrian- oriented clientele. The Specific Plan also calls for the eventual development of a number of plazas and civic uses as additional attractors of people to the area. Senior residential housing is proposed adjacent to the new senior center in the northwest portion of Specific Plan area. This would also be a ...." complimentary land use which should support the senior center and the surrounding retail Dublin Planning Department Page 13 Downtown Specific Plans 13 commercial establishments. The mixed-use area (high density residential and commercial combination) shown at the southeast corner of Amador Valley Boulevard/Amador Plaza Road would be compatible with the residential dev~lopment across Amador Valley Boulevard and the existing retail commercial uses on Amador Plaza Road. (""-, r\ In both the Downtown Core and the West Dublin BART Specific Plan areas, intensification of development through increased floor area ratios (FAR) is anticipated"The City's General Plan presently allows a up to a maximum FAR of .50 in each area for retail and office type uses. The Downtown Core Specific Plan suggests a maximum FAR of .79 for retail and office uses, and the West Dublin BART Specific Plan suggests a maximum FAR of .83 for retail and office uses, .,.&11.00 for strictly office use, and 1.00 for mixed-use development. An increased FAR of 1.00 for office use. as considered for approval by the City Council, on 6.98 acres within this Plan area has been evaluated in this assessment. Additionally, an increased FAR of 1.12 for the property adiacent to the . West Dublin BART Station is beino considered in coniunction with the, develoPlTlent . of a, 240 room hotel. Although these proposed FAR's under the specific plans are greater than those presently provided for in the existing General Plan, they are consistent with FAR's in traditional, thriving downtown areas, and in transit villaoesas proposed with the West Dublin BART Station development. This is not considered a sionificant increase nor would it create a sionificant irnpact. General plan amendments will be necessary to amend the allowed FAR for:fhedowntowriplanareas. and modify the land uses. The proposed FAR's for the plan areas have been analyzed in regard to traffic generation rates, and only minor traffic improvements are necessary to support the intensification of the proposed development under the plans (refer to Section VI, Transportation). Possible chanoes in trip oeneration rates and levels of service related to the land use chanoes from the oriqinal Plans are addressed in the Transportation/Circulation section of this document. 'these improvements have been programmed into the Specific Plans. Should FAR's exceedino these amounts be proposed with future land use applications, a specific traffic analysis and land use analysis would be required prior to approval to determine the impacts of the related intensified land Use on the roadway Systern.. Additionally, adoption of the Downtown Cor~ and West Dublin BART Specific Plans will require that . portions of the previously adopted (1987) Downtown Specific Plan be repealed to modify sections of the document relative to Development Zones 1,2,3,4,7,8,10 and 11, which are within these specific areas. Following Plan adoption, amendment of the City's Zoning Ordinance will be necessary. There are no proposed land use changes or modifications for the Village Parkway Specific Plan area. The present General Plan allows up to a maximum FAR of .50 for the Village Parkway area, and the average FAR in that area is currently .26. Therefore, further intensification in this plan area up to a FAR of .50 would be within the range permitted under the present General Plan. No general plan amendment will be necessary in conjunction with adoption of this Specific Plan. b) Conflict with applicable environmental plans or policies? NI:The City of Dublin has adopted no other city-wide or specific environmental plans or policies which would affect this project. No impacts would therefore result c) Incompatibilities with existing land use in the vicinity? NI. The proposed land uses to be established with the Specific Plans would be compatible with and support the surrounding retail commercial uses i in the three areas (refer to Com.ment a, above). Non-confprmino uses in the Specific .Plan area J would be reviewed in accordance with the City's established zoning reoulations. There will, therefore, be no impacts related to land use compatibility. ~,,', \,d). Effect on agricultura/ operations or soils? Nt. The site has been used for commercial uses since the f early 1960's. No agricultural operations exist in the subject areas or the, surrolll1l:iing areas of the City.. No impacts would therefore result. .. Dublin Planning Department Downtown Specific Plans Page 14 e) Disruption of physical arrangement of an established community? Nl. The project consists of three plans intended to direct the land use and future development in the City's central downtown area. The plan is proposed to be implemented over a five to teR seven year period, and will occur as a ...., gradual replacement of uses with new uses. This method of adaptive reuse of the areas will serve to integrate land uses, transportation and public improvements within the three Specific Plan areas not significantly disrupt the physical arrangement of the downtown. There will therefore be no impacts regarding disruption of established communities II. Population and Housing Environmental Settinq The city population as of January 1, 1999 was estimated by the State Department of Finance to be 28,707. 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 oJ 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. Under the proposed Specific Plans, a maximum of approximately 491 residential dwelling units would be introduced in the West Dublin BART area, and a maximum of approximately 150 residential dwelling units would be introduced in the Downtown Core area. This is not considered a significant increase for the region, and would actually establish housing closer to existing services and transportation than much of the residential development in the City. Proiect Impacts a) Cumulatively exceed official regional or local population projections? NI. The project involves primarily retail, office, lodging and similar uses. Although future residential and mixed uses are envisioned in the West Dublin BART Specific Plan and Downtown Core Specific Plan areas, such residential uses are intended to support transit-oriented development programs. Although the overall amount of residential development for the community is anticipated to increase, such increases would be less-than-significant. ~ b) Induce substantial growth in an area, either directly or indirectly? NI. The majority of the development that would occur under the Specific Plans would be commercial, office and other non-residential type land uses. Some new residential housing is proposed in the Downtown Core and West Dublin BART Specific Plan areas, but it would not result in a substantial amount of new dwellings, nor would it induce substantial growth in the area as land available for development is limited in this part of the City. Under the proposed Specific Plans, approximately 490 residential dwelling units would be introduced in the West Dublin BART area, and approximately 150 residential dwelling units would be introduced in the Downtown Core area. This is not considered a significant increase for the region, and would establish housing closer to existing services and transportation than much of the residential development in the City, thereby reducing some impacts associated with growth such as increased traffic generation. According to the City's General Plan, the Downtown Core and West Dublin BART Specific Plan areas are considered a Downtown Intensification Area which would. allow up to 200 dwelling units. It is also stated that the number may be increased if mid-rise, mixed-use buildings, such as that proposed in portions of the specific plan areas, achieve market acceptance. Additionally, the plan areas are currently serviced with water, sewer, and roads, and therefore, the specific plans are not considered growth inducing projects. ~ Dublin Planmng Department Downtown Specific Plans Page 15 ~o c) Displacement of existing housing, especially affordable housing? NI. The project site has been developed as a retail commercial and office downtown arE?a,O[t presently contains no housing. r--\ Therefore, there would be no displacement of housing units on the site. III. Soils and Geology Environmental Settinq The site lies within the Tri-Valley area, in the commercial core of Dublin. According to historic geologic studies in the area, the site is underlain by poorly consolidated, non-marine deposit sedimentary rocks of the TassaJaraF'Ormafion. The geotechnical investigation report prepared for the project indicates that the site is not within an Alquist-Priolo Fault Zone (1982). There are no mapped faults which are known to traverse the site, the closest Alquist-Priolo Fault Zone is the Calaveras Fault located along San Ramon Road approximately one-quarter mile to the west. The next nearest active seismic faults include the Hayward and the San Andreas Faults which are located approximately 9 miles southwest, and 27 miles west-southwest, respectively. The closest potentially active faults include the (1) Verona, which is located approximately 3 miles to the south, and (2) the Las Positas, which is located approximately 9 miles to the southeast. The soil conditions in the downtown area are summarized from previously prepared geotechnical studies as follows: Medium stiff to stiff lean clays to the maximum depth of about 41.5 feet below site grade (BSG). The upper 2 to 5 feet SSG consist of dark brown lean clays with varied gravel and sand content. The upper 6 to 12 inches of the clays were intermixed with wood debris suggesting that the upper, 6 inches was engineered fill. The near surface clays exhibit low to moderate plasticity, a low to moderate expansion potential~ and moderate shear strength. The consolidation tests indicate that the clays are I"'""\over-consolidated . and exhibit low comp:essibil!ty under the anticipated foundation lo~ds. Groundwater {was encountered m most of the test bonngs drilled below 10 feet BSG at depths ranging from 12 to 13 ':.,.' feet BSG. From a geotechnical standpoint, the area is suitable for proposed retail commercial and residential development with regard to support of shallow spread foundations and concrete slabs-on- grade. As this is a currently built and urbanized area, when excavation activities are proposed with individual projects on spe~ific sites, geotechnical studies specific to that property may be required at that time. . Proiect Impacts a). Is the site subject to fault rupture? NI. The risk of fault rupture on the site is anticipated to be low, since the nearest known active or potentially active faults lie a minimum of one quarter mile away. No impacts would therefore result. b) Is the site subjectto ground shaking? LS. The site as well as the encompassing region is anticipated to be subject to moderate to severe ground shaking from a number of active and potentially active faults in the greater Bay Area, including the Hayward fault, San Andreas fault and Calaveras fault. The ground shaking issue is less than significant for properties in the Specific Plan areas because new development constructed will be required to adhere to the requirements of the Uniform Building Code and other seismic safety standards as they are developed over the life of the Specific Plans. c) Is the site subject to seismic ground failure? NL Based on previous geotechnical reports and information for this area of the City, the risk of ground failure would be low. Routine enforcement of provisions of the 1997 Uniform Building Code and recommendations contained in geotechnical reports prepared for specific development projects will serve to reduce potential impacts of seismic ground failure to a lesS than significant level. r,..' , ... . \ Page 16 Dublin Planning Department Downtown Specific Plans d) Is the site .subject to seiche, tsunami hazards, including liquefaction? Nl. Geotechnical investigation reports for past projects in the downtown conclude that the risk of liquefaction in the downtown is low. This is based on the presence of clay soils on the site which are not prone to liquefaction. There are no major bodies of water located nearby which could be a source of seiche hazard. .."" e) Is the site subject to landslides or mudflows? Nl. The downtown project area is essentially flat with little change in slope; therefore, no impacts are anticipated with regard. to landslides or mudflows. f) . Is the site subject to erosion, changes in topography or unstable soil conditions? LS. The area is essentially flat and contains no unstable soil conditions. No significant changes in topography are proposed because the area has been previously graded the past to accommodate existing development. However, future development and construction within the area under the auspices of the three Specific Plans would result in grading and excavation for additional building foundations, underground utilities and similar purposes. There would be a possibility of erosion of graded material and construction debris off of construction sites. The City of Dublin requires preparation and approval of erosion control plans for all new construction where grading plans are requested. For development projects involving five acres of land are greater, preparation of Stormwater Pollution Prevention Plans are also required by the State Water Resources Control Board Adherence to standard erosion control plans and Stormwater Pollution Prevention Plans will ensure that any impacts related to erosion will be reduced to less-than-significant levels. g) Subsidence of land? Nl. Minimal subsidence would occur in the area, according to geotechnical reports prepared for past projects in the downtown. No impacts would therefore result. h) Expansive soils? LS. The soils have a low to moderate expansion potential and moderate shear strength. Foundations of future buildings and other structures proposed under the auspices of the Specific Plans will be reviewed by the City of Dublin pursuant to the Uniform Building Code to ensure that adequate foundations are provided. Less-than-significant impacts related to expansive soils are therefore anticipated. '-I i) Unique geologic or physical features? Nl. No unique geologic or physical features have been identified on any of the Specific Plan sites, based upon a review of a topographic survey and a field visit. No impacts are anticipated and no mitigation measures are required. IV. Water Environmental Settinq Surface water exists on perimeters of the West Dublin BART and Downtown Core Specific Plan areas in the form of open storm drainage channels owned by Alameda County Flood Control and Water Conservation District (ACFCWCD) Zone 7 site. Stormwater runoff within Specific Plan areas is directed to regional storm drain facilities owned and maintained by ACFCWCD, which underlie the SpeCific Plan areas. There are no creeks, wetlands or other bodies of water near the Specific Plan areas The entire 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. Proiect Impacts a) Changes to absorption rates? LS. The Specific Plan areas have been largely developed over the past thirty to forty years and covered with impervious surfaces, including buildings, parking areas, ''<itttrIII walkways and other paved areas. Small portions of the areas are either vacant or landscaped to Dublin Planning Department Page 17 Downtown Specific Plans 81- allow for drainage and irrigation. Construction of new buildings within the areas, under the auspices of the Specific Plans, would add new impervious surfaces, but would also add additional pervious surfaces in terms of plazas and more landscaping as required by the Specific Plans. Less-than- significant impacts to absorption patterns are therefore anticipated. f"""" \ b) Exposure of people or property to flood hazard? LS. Portions of the Village Parkway and Downtown Core Specific Plan are subject to flooding during 1 DO-year flood events .and are generally inundated with water during periods of intense andlor long-term rain fall. Representatives of the City of Dublin Public Works Department have indicated that sub-regional drainage improvements will be undertaken in the future as part of the City's Capital Improvement budget to alleviate flooding hazards. Programs to deal with flood hazards are included in the ViHage Parkway and Downtown Core Specific Plans. Less-than-significant impacts are therefore anticipated with regard to flood hazards. c) Discharge into surface waters or changes to surface water quality? NL Existing storm drainage facilities are planned to be used to accommodate stormwater runoff from the Specific Plan areas. Since the amount of stormwater runoff is not anticipated to increase above existing volumes (see comment a, above), no impacts are anticipated with regard to discharge into surface water. Future development projects undertaken under the auspices of the Specific Plans will be required to meet the water quality requirements of the City of Dublin's NPDES permit and the Alameda County Urban Runoff Clean Water Program. d) Changes in amount of surface water? NI. Adoption of the proposed Specific Plan would have no impacts to surface waters as all drainage shall be directed to the existing storm drainage system. No impacts to surface bodies of water are therefore anticipated. to;) Changes in currents or direction of water movement? NI. The project would not alter currents or direction of water movement in nearby water bodies since no substantial changes are anticipated to the volume of stormwater runoff. Changes in quantity of groundwater? NI. Approval and implementation of the three Specific Plans would not significantly alter existing ground water resources on or near the project site because all drainage is directed to the storm drainage system operated by Zone 7. Similarly, significant amounts of groundwater use are not anticipated, since representatives of the Dublin-San, Ramon Services District have indicated that adequate water supplies have been identified to serve the maximum amount of development envisioned in the proposed Specific Plans. g) Altered direction of groundwater? LS Nt. The project would not affect groundwater dIrection, since no significant subsurface construction is anticipated. In the event that subsurface excavation is proposed. adopted City standards require that specific development proiects. such as those reQuirino underoround parkino structures, prepare a' site-specific hydrolooical analysis with oeotechnical and soils analvsis to determine oroundwaterlevels. No sionificant impacts are anticipated related to altered direction of oroundwater. h) Impacts to groundwater quality? NI. The scope of the project is such that groundwater resources will not be affected, as discussed above. i) Substantial reduction of groundwater resources? LS. The project involves approval of three Specific Plans to upgrade the appearance and land uses in downtown Dublin. Since more intensive land uses r, are anticipated in the Plans above that allowed in the current General Plan, some increase in the use of water IS anticipated. Representatives of the Dublin-San Ramon Services District have indicated, that adequate water supplies have been identified and addressed in future District plans to serve the Dublin Planning Department Page 18 Downtown Specific Plans maximum amount of development envisioned in the proposed Specific Plans. Therefore, the projected level of water use is expected to be less-than-significant. v. Air Quality \tttII Environmental'Settinq 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 airflow into the southern portions of the Valley is accomplished through two passages in the surrounding 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. Proiect Impacts a) Violation of air quality standard? LS. 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 construction of new buildings under the auspices of the Specific Plans would generate temporary increases in dust and particulate matter caused by 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). The City of Dublin requires the approval and ...., implementation of a Construction Impact Reduction Plan as a standard condition of approval for new construction projects which will reduce short-term air quality impacts to a level of insignificance. Buildout of the maximum development of the three Specific Plans would add additional vehicular traffic to this portion of Dublin. These additional vehicles would generate quantities of carbon monoxide, reactive organic gasses, nitrous oxide, sulfur dioxide and particulate matter (PM10). However, the location of the Specific Plans near major regional transportation corridors (1-680 and Dublin Boulevard), and the fact that the intent of the West Dublin BART and Downtown Core Specific Plans is to promote transit-friendly development results in conformity with the Bay Area Air Quality Management District's Clean Air Plan. The short-term and long-term impacts to air quality of approving and implementing the three Specific Plans would, therefore, be less-than'-significant. b) Expose sensitive receptors to pollutants? LS. As stated in V-a above, the impacts to air quality of the project will be less-than-significant both on the long- and short-term. The project, if approved and constructed, would add some vehicular trips to the project area, but the development of the new West Dublin BART Station would also reduce a portion of the vehicular trips in the area. This increase in vehicular trips is minor considering the fact that many of the trips are multi-purpose trips. It is unlikely that the project would expose additional sensitive receptors, future visitors, and residents to significantly higher concentrations of vehicle related pollutants. Any impacts related to this issue would be less-than-significant. c) After air movement, moisture, temperature or climate? Nl. The Specific Plans are intended to encourage the same general type of development as currently exists on each of the project sites. ..J Dublin Plannmg Department Downtown Specific Plans Page 19 ~4 Although building heights may be somewhat higher than currently found on the site, no substantial interference regarding prevailing wind patterns or climatic conditions is anticipated. r\ d) Create objectionable odors? NI. Permitted uses allowed by the Specific Plans include primarily retail, office, entertainment, lodging and residential land uses, none of which are associated .with the release of significant amounts of objectionable odors. Therefore, no impacts are anticipated. VL Transportation/Circulation [Note: The following section is based on an analysis of the traffic and transportation performed byOmni;.. Means, Transportation Consultants in AUQust 2000, with updates in September. November and December 2000.] Environmental SettinQ Major roadways serving the site include: o . Interstate 580, a six-lane east-west freeway connecting Dublin with nearby local communities such as Livermore and Pleasanton and regional destinations, such as Tracy and Oakland. In the vicinity of the proposed project, 1-580 carries between 160,000 and 187,000 vehicles per day. Nearby interchanges include 580/680; Dougherty Rd.lHopyard Rd. and Hacienda Dr. Interstate 680 is a six-lane north-south freeway connecting Dublin with local communities in the Tri-Valley area and regional destinations north and south of Dublin.1Jli~, freeway accommodates between 123,000 and 144,000 vehicles per day with interchanges at Alcosta Blvd., Interstate 580 and Stoneridge Drive. Dougherty Road extends in a north-south direction east of the Specific Plan areas. A major arterial roadway, Dougherty Road has four travel lanes north of Dublin Boulevard. South of Dublin Boulevard, the roadway widens to six travel lanes as it crosses over 1-680, a full-access interchange for eastbound/westbound traffic is located at Doughertyll-580. In the Dublin Boulevard area, Dougherty Road provides access primarily to commercial and retail areas.

Dublin Planmng Department Downtown Specific Plans Page 21 ~LP ! I ! The Livermore Amador Valley Tfansit Authority ("WHEELS") provides bus transit service through the , , r Dublin area. Bus routE?S sE?fving the downtown Dublin area include Routes 3, 4, 10 and 201/202. Regional transit to and from the Dubli"n area is provided by the Bay Area Rapid Transit District (BART). BART opened a Dublin/Pleasanton station in the latE? 1990's, located approximately one mile east of the project site. A recent proposal has been submitted to BART toc:;onstruct apoVllJ1town Dubl.in ~tation within the West Dublin BART Specific Plan area at the terminus of Golden Gat~ Drive, approximately 1/2 mile south of this Specific Plan area. Bikeways exist or are proposed on Amador Valley Boulevard and Dublin Boulevi:!rd,. ..A..rni:!qPr,Yi:!lIey Boulevard is presently designated for a Class II bikeway lane, which is designed with a one~way striped lane for bicycle travel on the roadway. Dublin Boulevard is proposed for a Class 'II bikeway lane, to be opened with the. completion of the roadway improvements. Public sidewalks have been constructed adjacent to many of the streets within and adjacent to the Specific Plan areas. The City commissioned a traffic consultant (Omni-Means, transportation consultants) to prepare a traffic analysis regarding transportation and circulation impacts of approving and implementing the three Specific Plans. . General Plan Transportation PolicVF=~~me3~ork The Generi:!1 Plan, measures and evaluates traffic congestion conditions of the roadway network by using intersection level of service ("LOS") analysis. The LOS analysis describes the operational efficiency of an intersection by comparing the volume of critical traffic movements to intersection capacity and ,..-"deterrninipg>average delays. LOS can range from "A," representing free-flowing conditions, to "F," t \ representing very severe congestion and intersection breakdown. The General Plan adopts LOS D or better as the acceptable LOS for all routes of regional significance , (these routes include: Dublin Blvd., Dougherty Rd., Tassajara Rd., and San Ramon Rd.). Development '~and road improvements should be phased so that the LOS does not deteriorate below LOS D 0J/C .91 or greater) (General Plan Guiding Policies 5.1.1 B and C). Sionificance Criteria Based upon General Plan policies, an intersection impact is considered significant if it causes the overall intersection LOS, or a movement LOS in the intersection, to fall below LOS D. . Proiect Impacts a) Increased vehicle trips or traffic congestion? LS. Th~ proposed project would increase vehicle trips and traffic congestion on the local roadway network, which could deteriorate existing levels of service on some affected roadways. Table 1, summarizes existing traffic conditions in and around the Specific Plan sites, which also includes anticipated traffic from approved but not yet constructed projects. The table also shows anticipated traffic impacts for the same intersections at full build out of maximum Specific Plan densities. For two of the intersections, Golden GatelDublin Boulevard and A~ador Plaza/Dublin Boulevard, projected traffic would exceed City thresholds of significance. For these two intersections, the Specific Plans require the installation of traffic improvements as part of Specific Pian development to raise the future Level of Service to comply with City standards. C'\ Additional roadway widening improvements would be needed with the projected traffic volumes. Golden Gate Drive would require widening to four travel lanes with two-way left-turn lanes between Dublin Planning Department Downtown Specific Plans Page 22 feet. Accordino to the City's traffic consultant. this would result in more traffic trips per day than the residential use at the same location. Because of this, intersections in the vicinity may operate at' LOS uD" rather than LOS "C". LOS "0" is oenerally considered an acceptable level of service. so althouoh trips would increase, it would not be a sionificant increase and will be adequatelv addressed bv the policies and proorams in the Specific Plans. At their meetino on October 24. 2000. the Planninq Commission suqoested revisions to be included in the Downtown Core Specific Plan, and also in the General Plan Amendments for the proiect. The Commission suooested a chanoe in the FAR for a 2.55 acre Retail/Auto use property to reflect a request by Kenneth and Marc Harvev of Dublin Honda for property on Amador Plaza Road. The chanoe modifies the FAR from 0.20 (or 22,420 square feet with the existino development on the site) to 0.79. resultino in a development potential of 87,750 square feet. This chanoe would provide for consistency between the FAR of the Honda dealership property and that of the adiacent property. former site of Shamrock Ford. at the corner of Dublin Boulevard and Amador Plaza Road. It is not anticipated that traffic in the area would increase with this FAR increase as the existino use would remain the same, and the additiona.1 square footaoe would be utilized for storaoe and office space associated with that use. The policies and proorams in the Specific Plans should be adequate for the proposed land use. Any land use chanoe application for this property in the future would require a land use and traffic analysis to evaluate the impacts on the Specific Plan area. '., .."" For the Village Parkway Specific Plan area, the City Council appointed a Task Force which met over a six-month period to discuss and direct the revitalization of the business community along the segment of Village Parkway between Amador Valley Boulevard to the north and Dublin Boulevard to the south. To accomplish this revitalization effort, it was decided by the Task Force that slowing traffic and providing better parking opportunities close to businesses would create a more pedestrian and shopper friendly environment, thereby stimulating the economic growth of busines$es and increasing the activity level in the area. Four different options for roadway improvements along Village Parkway were evaluated during the specific plan development process, along with the existing roadway configuration as shown in Exhibit 7 A of the Specific Plan. The following is a brief description of each of the Village Parkway roadway alternatives considered. Exhibits illustrating the ..." alignment and cross section of Village Parkway for each alternative are contained in Appendix A5 of the Village Parkway Specific Plan. Alternative 1: The Village Parkway Specific Plan Task Force reviewed the various options for the roadway, all of which contained diagonal parking to bring people closer to business storefronts and to change the streetscape in the area. Alternative 1, as shown in Exhibit 10A of Appendix A5 of the Specific Plan, would provide four lanes of traffic on Village Parkway (two lanes in each direction) combined with diagonal parking along the street frontage in selected locations. There are approximately 60 existing parallel parking spaces along Village Parkway at this time, and 121 parking spaces could be provided with this alternative. A four-foot class III bicycle lane would be located between the diagonal parking and the right traffic lane. The sidewalk would be widened from five feet (existing right-of-way is eight feet) to 10 feet to provide enough space for increased pedestrian use. Two new crosswalks for pedestrians would be provided in mid-block locations with caution signals. Each traffic lane would be 12 feet and the center median would be reduced from 16 feet to 14 feet in width. In the Consultant's Report of the Transportation Impacts for the Proposed Village Parkway, Downtown Core,' and West BART Station Specific Plans prepared by Omni-Means for the Downtown specific plans, the consultant determined that this alternative would create the least potential roadway impacts of the four alternatives and recommended it for implementation. This determination was based on the following: 1) four travel lanes would be maintained; 2) diagonal parking would provide additional spaces close to business frontages; and, 3) bicycle traffic would be provided on the street (however, this could create some conflicts between motorists backing out of spaces and bicyclists). Some conflicts may occur between through vehicles and those.."",; Dublm Planning Department Downtown Specific Plans Page 24 ~ r'\ t ' backing out of spaces; but the bike lane should provide a buffer zone, thereby reducing tne potential for conflict. The totalright-of-lNay (ROVV) required for this option would be 115 feet. As the roadway ROW is currently 100 feet, an additional seven feet six inches of ROW on each side of the street would need to be obtained from property owners. Implementation of this alternative would require a public/private partnership, or joint partnership b~tween private property owners and the City to balance the cost of improvements. This alternative requires a high degree of cooperation and commitment by both the City and the property owners on Village Parkway to be successful. The preliminary cost estimate for improvements related to this alternative is $2,005,000. Alternative 2 - Alternative 2, as shown in Exhibit 7B of the Specific Plan (see attached disgram) and Exhibit 10B of the appendix, would provide four lanes of traffic on Village Parkway (two lanes in each direction) combined with diagonal parking along the street frontage in selected locations, and the bicycle lane would share the sidewalk with pedestrian traffic. The sidewalk would be widened t012 feet to provide enough space for the shared use. Two new crosswalks for pedestrians would be provided in mid-block locations with caution signals. Each traffic lane would be 12 feet and the center median would be reduced from 16 feet to 14 feet in width. The total right-of-way (ROW) required for this option would be 118 feet. As the roadway ROW is currently 100 feet, an additional nine feet of ROW on each side of the street wOLJldneed to be obtained from property owners. The consultant's report determined that this alternativ~ was _adequate for roadway circulation; however, maintaining the bike lane on the sidewalk cpulq be problematic in the downtown retail district due to pedestrian/bicycle conflicts on the adjacent sidewalks. Additionally, the alternative does not provide a buffer area between the outside lanes, and vehicl~s, i:>acking out of the diagonal parking spaces. This could be disruptive to traffic flows during peak hours of traffic. Implementation of this alternative would require a public/private partnership, or joint partnership between private property owners and the City to balance the cost of improvements. The preliminary cost estimate for improvements related to this alternative is $2,170,000. Alternative 3 - The alternative preferred by the Task Force was Alternative 3, as shown in Exhibit 10C, which would provide two lanes of traffic on Village Parkway (one lane in each direction) combined with diagonal parking along the street frontage in selected locations. A total of 81 parking spaces could be provided with this alternative. A six-foot Class III bicycle lane would be located on the roadway between the diagonal parking and the through traffic lane. Two new crosswalks for pedestrians would be provided in mid-block locations with caution signals. Each traffic lane would be 12 feet and the center median would, be reduced from 16 feet to ,14 f~etin width. The Task Force also suggested that the median be reduced in height for better visibility for pedestrians crossing the street. The total right-of-way (ROW) required for this option would be 100 feet. A~the roac:lway ROW is currently 100 feet, no additional ROW would need to be obtained from property owners. The amount of ROW needed for this alternative is less than that., required for the other options considered, but it would reduce the number of through traffic lanes from four to two, thereby slowing traffic considerably. In slowing traffic on the roadway, Alternative 3 would also create additional congestion on Village Parkway during peak hour periods, and traffic may be diverted to Amador Plaza Road and streets with less capacity in the vicinity. With the existing level of traffic plus approved projects' and BART's estimated traffic volume, the traffic consultant's estimate is that the level-of-servic:e (LOS) on Village Parkway would operate at LOS F (unacceptable level), decreasing from LOS C (acceptable level) with this alternative. Additionally, the LOS at the Dublin Planning Department Downtown Specific Plans Page 25 intersections of Amador Valley BoulevardNillage Parkway and Dublin BoulevardNillage Parkway would operate at LOS D during the AM peak hour, and LOS F during the PM peak hour Implementation of this altemative would require a public/private partnership, or joint partnership """" between private property owners and the City to' balance the cost .of improvements, but to a lesser degree than Alternative 1 and 2. This alternative requires cooperation and commitment by both the City and the property owners on Village Parkway to be successful. The preliminary cost estimate for this alternative is $1,050,000, and is the lowest cost alternative when compared to the other three alternatives. Alternative 4 - Alternative 4, as shown in Exhibit 100, would provide four lanes of traffic on Village Parkway (two lanes in each direction) and a four..:foot bicycle lane. Diagonal parking would be provided along the frontage of businesses in selected locations, but it would be separated from street traffic by narrow medians. A total of approximately 106 parking spaces would be provided with this alternative along Village Parkway. Drive aisle entrances would provide access to these separated parking areas. Two new crosswalks for pedestrians would be provided in mid-block locations with caution signals. Each traffic lane would be 12 feet and the center median would be reduced from 16 feet to 14 feet in width. The total right-of-way (ROW) required for this option would be 128 feet. As the roadway ROW is currently 100 feet, an additional 14 feet of ROW on each side of the street would need to be obtained from property owners. This alternative would increase the distance between roadway traffic and the businesses on Village Parkway, and may not meet the objective of slowing traffic and providing a more pedestrian oriented streetscape, as the width of the ROW would be substantially increased. Implementation of this alternative would require a public/private partnership, or joint partnership between private property owners and the City to balance the cost of improvements. The,.. '.' preliminary cost estimate for this alternative is the highest. of the four alternatives at $3,130,000. ....." Therefore, as the cost is extremely high and it would not meet the basic objective of providing parking close to the street and businesses with better pedestrian access, it is not recommended as a viable alternative. Staff has several concerns reoardino narrowino Villaoe Parkway to two lanes of traffic and addinQ diaoonal parkinQ. as preferred by the Task Force. Vehicle trip diversion may occur. as discussed in the previous section. and adversely affect the adiacent neiahborhood to the east. This could affect the quality of . life for that portion of the City residential area by creatinq. safety hazards for residents and children attendino the neiqhborhood school. Noise levels could also increase in the area with' the additional cut-throuoh traffic. Additionally. the Alameda County Fire Department and Dublin Police Department have expressed concerns related to community safety, response time, and the creation of roadway hazards in the event that Villaoe Parkway is reduced to two lanes of traffic with diaoonal parkino within the existinQ rioht-of-way. Another option for the alignment of Village Parkway, which is the staff recommended option (see attached diaoram), is to maintain the existing roadway without expansion, and continue the use of parallel parking on both sides of the street. Improvements in the streetscape and sidewalk could be provided as described in the section of this document on design to encourage increased pedestrian use in the area. Additionally,' joint/shared parking should be ,encouraged between properties, with fences removed which impede pedestrian access. This option would require less capital funds for implementation and would create less roadway impacts. A letter has been' received from the Alameda County Conqestior.l ManaQement Aoency (ACCMA) commentino on the transportation and circulation analysis prepared for the Specific Plans. The City's traffic consultant has responded to these comments in a letter dated December 8. 2000.

LS. Approval of the three Specific Plans and construction of improvements based on the Specific Plans would increase the demand. for on-site parking within each of the three areas. Parking demand would also be increased due to the planned presence of the proposed West Dublin BART station, the development of which is not part of the Specific Plan project. Requirements included in each of the Specific Plans require that all new land uses proposed pursuant to a Specific Plan include on-site parking to meet current City of Dublin parking'requirements.ExistinQ 'uses are assUmed to provide sufficient parkino, with, applicable City standards on-site at the time of orioinal construction and development. The .Specific Plans provide that ~xceptions to parkino reoulations may be allowed for shared use of parking facilities, or in instances where the Plannino Commission or City Council find evidence based on a parkino analysis that a reduced parkino ratio is apPr0priate due to the proximity of the use to public transit service. The Specific Plans also provide that Provicion of additional parking facilities maybe reviewed and reouiredwill bo rovimvcd as individual Site Development Review applications are submitted to the City of Dublin for new construction projects. This review process will ensure that adequate parking is provided and any parking impacts would be less-than-significant. e) Hazards or barriers for pedestrians or bicyclists? Nt. The proposed Specific Plans would require construction of new bicycle and pedestrian facilities to encourage non-auto travel modes. No impacts are therefore anticipated. f) Conflicts with adopted policies supporting alternative transportation (e.g. bus turnouts, bicycle racks)? Nl. Each of the Specific Plans require the installation of some new facilities to support enhanced bus service to each of the three sites. However, the additional facilities would be within areas presently served by transportation services. The new facilities would be consistent with . adopted policies supporting alternative transportation as they would provide more opportunities to use varying modes of transportation. Therefore, no impacts are foreseer.. g) Rail, waterborne or air traffic impacts? Nl. The proposed project is not sited near operating railroad facilities, near a navigable waterway or near an airport. Although the West Dublin BART Specific Plan is located near the proposed West Dublin BART station, the intent of the Specific Plan is to o Dublin Plannmg Department Downtown Specific Plans Page 28 promote complementary land uses adjacent to the planned BART station. Therefore, no impacts are anticipated. ~ VII. Biological Resources Environmental Settinq The Specific Plan project sites are located in highly urbanized areas. With the exceptions of County drainage channels on the periphery of two of the Specific Plan areas, no wetlands or other bodies of water exist in or near the site. Existing vegetation includes introduced ornamental landscaping within planter areas. Proiect Impacts a) Endangered, threatened or rare species or their habitats (including but not limited to plants, fish, insects, animals and birds) NI. The Specific Plan Areas are existing, urbanized downtown areas. The majority of the properties within the plan areas are fully developed. No such species have been observed in the project areas based on field observations conducted in July 2000. b) Locally designated species (e.g. heritage trees). NI. No heritage trees are located on the site. c) Locally designated natural communities (e.g. oak forest, coastal habitat) NI. Only introduced, ornamental vegetation associated with urban development is found on the site. d) Wetland habitat (e.g. marsh, riparian and vernal pool)? NI. No wetlands exist on the project site. e) Wildlife dispersal or migration corridors? NI. The Specific Plans represent in-fill development within '...." an existing urbanized downtown area. There are no wildlife or migration corridors on the site; therefore, no impacts would occur to such resources VIII. Energy and Mineral Resources Environmental Settinq Based on the previous geotechnical surveys of specific properties in the Specific Plan area, no known deposits of minerals exist on the project site. The. Conservation Element of the General Plan does not reference any significant mineral resources on the project site or in the general area. Proiect Impacts a) Conflict with adopted energy conservation plans? Nl. The proposed project will not conflict with goals, policies or programs established in the Dublin General Plan regarding energy or energy conservation. b) Use nonrenewable resources in a wasteful and inefficient manner? Nl. The proposed project is not anticipated to use resources in a wasteful manner. The project will be constructed in accordance with the Uniform Building Code and Title 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 ".J Dublin Planning Department Downtown Specific Plans Page 29 Q;r generated by residences, business and industrial establishments by promoting recycling and similar programs. ("'\ 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 project site is not located in an area designated by the California State Department of Conservation, Division of Mines and G~Qlogy, as having sufficient mineral resources that are suitable as marketable commoditi~s. No .impacts are therefore expected. IX. Hazards Environmental Settinq . The Specific Plan areas are located in previously developed commercial. office and similar non- residential areas. Existing uses within the West Dublin BART and Downtown Core Specific Plan areas include automobile sales and service uses. Operation of these facilities use oil, grease, solvents and other potentially hazardous materials. It is anticipated that some or all of these uses would remain in business after adoption of the two Specific Plans; however, storage and handling of potentially hazardous materials is controlled by the Alameda County Fire Department, Alameda County Health Department, Regional Water Quality Control Board and other regulatory agencies.. Proiect Impacts a) A risk of accidental explosion or release of hazardous substances including but not limited to oil, pesticides, chemicals, or radiation? NI. With the exception of auto-oriented uses, none of ,the land uses permitted by the proposed Specific Plans would store, use or transport significant quantities of hazardous substances. No impacts are therefore anticipated with regard to hazardous substances. . r\ " k b) Possible interference with an emergency response plan or emergency evacuation plan? NI. Future site development plans proposed within the three Specific Plans will be reviewed by the Dublin Police Department, Dublin Planning Department and Alameda County Fire Department to ensure that adequate emergency evacuation is provided per City requirements. No impacts are therefore anticipated. c) The creation of any health hazard or potential health hazards? Nl. Development of land uses and other facilities pursuant to the three SpeCific Plans are not anticipated to generate significant health hazards, since permitted uses would generally include commercial, office, entertainment, restaurant and residential uses. No industrial or manufacturing land uses are proposed. No impacts are therefore anticipated. d) Exposure of people to existing sources of potential health hazards? LS. Generally, new land uses in the Specific Plan areas would include commercial, office, lodging, entertainment and similar uses, none of which would involve creation of a health haz(lrd. New d~velopment that may be located near automobile serving uses could have the potential to expose employees and visitors to health hazards; however, the potential for exposure of people to health hazards from existing uses will be reviewed during the Site Development Pian process to ensure compliance with all applicable health and safety regulations. Less-than-significant impacts are therefore expected. C'.. e) Increased fire hazard in areas with flammable brush, grass or trees? LS. The proposed Specific Plan areas are located in urbanized areas and existing uses have been constructed in compliance with Uniform Fire and. Building Code requirements. Existing and future landscaped areas will be permanently irrigated and maintained so that the potential for fire is reduced to a less-than-significant level. . Dublin Planning Department Downtown Specific Plans page 30 X. Noise ,..", Environmental Settinq The General Plan identifies that the normally acceptable maximum outdoor Ldn noise level is 70 dBA for commercial areas, while interior areas have a maximum noise level of 45 dBA. The primary existing source of noise in the vicinity of the three Specific Plans is vehicle traffic, autos and trucks, traveling on adjacent freeways and surface streets. It is anticipated that significant portions of all three Specific Plan areas are subject to exterior noise in excess of 70 dBA. Proiect Impacts a) Increases in existing noise levels? LS. Approval of the three Specific Plan and construction of improvements pursuant to the Plans is expected to incrementally increase noise levels in and adjacent to the three planning areas. Noise increases would include temporary noise increases, associated with construction activities and long-term permanent noise levels, associated with additional vehicular trips and operational noise (mechanical noise, unloading of goods and similar activities). Given the high levels of noise already on the site caused by nearby freeways, increases in .noise levels are anticipated to be less-than-significant. b) Exposure of people to severe noise levels? LS. The West Dublin BART and Downtown Core Specific Plans both allow residential dwellings as permitted uses. Site specific review will be performed during Site Development Review for residential projects to ensure compliance with City interior and exterior noise standards. Noise studies may be required for individual projects. With adherence to City noise standards, less-than-significant impacts would occur with regard to exposure of people to ...." noise impacts. XI. Public Services. Environmental Settinq The project site is served by the following service providers: · Fire Protection. Fire protection is provided by the Alameda County Fire Department, under contract to the City of Dublin, which provides structural fire suppression, rescue, hazardous materials control and public education services. · Police Protection. Police protection is provided by the City of 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, street trees and other public facilities. Dublin's Civic Center is located at 100 Civic Plaza. . Dublin Planning Department Page 31 Downtown Specific Plans parks, .., q~ . Other qovernmental services. Other governmental services are provided by the City of Dublin including community development and building services arid related governmental services. Library service is provided by the Alameda County Library with supplemental. funding by the City of Dublin. .(l 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. Future applicants for development pursuant to the Specific Plans would be required to pay this fee. Environmental Impacts a) Fire protection? LS. Approval of the three Specific Plans and future construction in compliance with the Specific Plans would incrementally increase the demand for fire and emergency calls for service since additional building square footage would be added to each site. As part of the site development review process for individual buildings, specific fire protection requirements will be imposed to ensure compliance with applicable provisions of the Uniform Fire Code. Such measures would include but not limited to installation of new fire hydrants, fire extinguishers and similar features. Based on standard City fire protection requirements, fire protection impacts would be less-than-significant. b) Police protection? LS. Approval of the three Specific Plans and future construction in compliance with the. Specific Plans would incrementally increase the demand for police calls for service since additional building square footage would be added to each site. As part of the site development review process for individual. buildings, specific security requirements will be. imposed to ensure compliance with applicable provisions of the City's building security ordinance. Such measures would include, but not be limited to, installation of appropriate locking devices, installation of security lighting and similar features. Based on standard City security requirements, police protection impacts would be less-than-significant: c) Schools? LS. The West Dublin BART and Downtown Core Specific Plans each call for a residential component. Although the size, type and orientation of dwellings that would be proposed for development would likely generate a minimal amount of students to be served by the Dublin Unified School District, there could be an incremental increase in the number of school-aged children. As part of subdivision and site development review of future residenti(;il projects, coordination will occur with school district officials to ensure that less-than-significant impacts would result, . d) Maintenance of public facilities, including roads? LS. Approval of the Specific Plans and construction of individual development projects pursuant to the Plans .would incrementi3lly increase the need for maintenance of public facilities. Payment of pUblic facility fees to the City of Dublin by individual projects would ensure that future maintenance impacts would be reduced to less:than..significant levels. e) Other governmental services? LS. Approval of the Specific P!;;lns would represent incremental increases in the demand for general governmental services. Payment of the City's Public Facility Fee by individual project developers would offset any impacts .caused by such projects, reducing any impacts to a less-than-significant impact. r-.

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. b) Communication systems? NI. Pacific Bell and AT&T Cable, communication facilities presently exist in the near each of the three Specific Plan sites. c) Local or regional water treatment or distribution systems? NI. Water services are provided to the area by the Dublin San Ramon Services District (DSRSD). According to representatives of the District, adequate long-term water resources exist to serve future development envisioned in each of ...., the Specific Plans. However, an upgrade to a 12"loop waterline from Regional Street to Amador Plaza Road may be required with new development, but the District will need to evaluate the system when specific projects are submitted. d) Sewer or septic systems? LS. Sewer services are provided by DSRSD. 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 outfall line for eventual disposal into San Francisco Bay. DSRSD officials indicate that adequate capacity exists within the regional treatment facility to accommodate the proposed Specific Plans. However, the District may need to replace the 8" sewer main line with a 12" line in Dublin Boulevard if development occurs at the intensity proposed with the Specific Plan. This will also require further evaluation when specific projects are submitted. Less-than-significant impacts would therefore result regarding sewer treatment facilities. e) Storm water drairiage? LS. This topic was previously addressed in Section IV, Water. f) Solid waste disposan 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. ..., Dublin Planning Department Downtown Specific Plans Page 33 qto r\ Although approval of the proposed Specific Plans will incrementally increase the amount of solid waste, any such increases will be insignificant because the existing facility would be able to be accommodated given the existing solid waste facilities and resources. As stated in VIlI-b above, the City is mandated by AB 939 to reduce the solid waste ,stream generated by residences, businesses and industrial establishment by promoting recycling and similar programs. g) Local or regional water supplies? NI. DSRSD staff indicate that adequate long-term water supplies are available from Zone 7 and other sources to serve thE;l proposed project. XIII. Aesthetics. Environmental Settinq The Specific Plan areas are located within existing urbanized areas and are not located adjacent to. scenic highways. Environmental Impacts ,r' a) Affect a scen(c vista or vieW? Nt. The proposed Specific Plan includes development programs to intensify existing land use patterns. Each Specific Plan contains height and bulk requirements to ensure. that scenic vistas from surrounding areas would not be blocked. The Specific Plans establish 'a heiqht limit of six stories for the Downtown Core and Villaoe Parkway areas. . The Planninq Commission has recommended a heioht limit of ten stonesforfneWestDublin BART Specific Plan. area to the. City Council. which is common with development in most urban downtowns and development near freeways. The City Council maY determine that ten stories is appropriate for this area due to its location near the BART Station. a maior-transit facilitv. and the 1-580 and 1-680 freeways. Review of individual proiects in accordanc;evvith ,. the' desjon ouidelines related to reduction. in bulk and quality of desion as detailed in the Specific Plan will result in less-than- sionificant impacts on views. b) Have a demonstrable negative aesthetic effect? NI. Each Specific Plan contains design guidelines to ensure that new development projects occurring pursuant to an approved Specific Plan would result in an aesthetically pleasing manner and would include additional landscaping. As part of the Specific Plan programs, new public plazas, streetscape elements and other improvements would be completed to improve aesthetic conditions. Therefore, no negative aesthetic impacts would be created. c) Create light or glare? LS. Proposed new uses constructed pursuant to the Specific Plans could incrementally increase light levels in each of the Plan areas. New sources of light would include street lighting, plaza lighting and building security lighting with new development projects and, possible, extended hours of business. However, a significant. amount of exterior lighting has already been installed within each of the Specific Plan areaS. Standard conditions of approval for individual development projects will require that pole-mounted lights shall be equipped with cut-off luminaires. Wall-mounted lights must also be equipped with cut-off lenses. Any additional light or glare created would be therefore be minimalless-than-significant. XIV. Cultural Resources Environmental Settinq r . The project site has been developed for a range of commercial and similar non-resid.ential areas. No cultural resources remain on the graded surface of the site. Since surface improvements are less than fifty years old or newer, no historic resources exist on the site. Dublin Planning Department Page 34 Downtown Specific Plans Proiect Impacts a-d) Disturb paleontological, archeological, religious or cultural resources? LS. No cultural resources '.J remain on the graded surface of the site. Any cultural resources buried beneath the ground surface would be re-buried by individual development projects proposed to implement a Specific Plan. The possibility exists that cultural resources including paleontological, cultural, historic or archaeological could be buried on the site and discovered during excavation. Each individual project proposed pursuant to a Specific Plan will be conditioned to protect buried archeological and paleontological resources. With adherence to this condition, less-than-significant impacts would result to cultural resources: xv. Recreation. Environmental Settinq Each of the Specific Plan areas have been developed with commercial, office, entertainment, lodging and similar uses. No parks or recreational facilities exist on any of the Specific Plan sites. Proiect Impacts a) Increase the demand for neighborhood or regional parks or other _ recreational facilities? LS. Construction of new residential dwellings pursuant to the West Dublin BART and Downtown Core Specific Plans would incrementally increase the demand for local and regional parks and recreational facilities. However, it is anticipated that the majority of new dwellings would either be oriented to senior citizens or non-family households, typical of higher density, multi-family housing. Therefore, expected park and recreational demand would be less-than-significant. Future builders of residential....., dwellings would be also be required to pay a Public Facility fee to the City of Dublin, which includes a contribution toward construction of new parks in the city. Additionally, the plans call for some plaza areas to be created in the three specific plan areas which could provide opportunities for outdoor recreational activities. b) Affect existing recreational opportunities? NI. No recreational opportunities exist on the site that would be affected by the project. 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 communny, 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? NI. The preceding analysis indicates that adoption and implementation of the Village Parkway Specific Plan, the West Dublin BART Specific Plan and the Downtown Core Specific Plan would 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? Nl. The project represents an example of in-fill development near a proposed major transit station which will be sited in an area surrounded by major regional transportation corridors. No. long-term environmental impacts will occur. '.J Dublm Plannmg Department Downtown Specific Plans Page 35 q~ 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). LS. Although incremental increases in certain areas can be expected as a result of constructing this project, including additional traffic, short-term 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 anticipated amount of development planned as part of the three Specific Plans. ~. f d) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? NI. Due to project design and site characteristics, approval and implementation of the three Specific Plans involve no impacts that would adversely effect human beings, either directly or indirectly.

San Francisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village iv EDAW Introduction . r. , JDLt .,..... f . \' 1 INTRODUCTION r'" I 1.1 PURPOSE OF THE SUPPLEMENTAL ENVIRONMENTAL IMPACT REpORT .r:-- , This Supplemental Environmental Impact Report (Supplemental EIR) has been prepared to evaluate the environmental impacts associated with development of the West DublinjPleasanton BART Station and Transit Village Project located in the cities of Dublin and Pleasanton. The proposed project would include development of the San Francisco Bay Area Rapid Transit District (BART) West DublinjPleasanton Station; a 17 -acre transit village that would include a mix of residential, office and hotel uses; parking facilities for the BART station and the transit village uses; pedestrian bridges over Interstate to access the BART stati()n; and a bus intermodal facility. ..-. i On February 8,1990, BART certified the Environmental Impact Report for the DublinjPleasanton Extension Project (DPX EIR) and approved the DPX project. The DPX EIR evaluated the environmental impacts associated with extending the BART rail line through the Livermore/Amador Valley area into the communities of Castro Valley, Dublin, Pleasanton, and Livermore. A specific component of the DPX EIR included an evaluation of the environmental impacts associated with construction of a West Dub1injPleasanton BART station and joint development on the adjacent parcels. The joint development assumed for the West DublinjPleasanton station included either high-density retail or office uses on the Pleasanton parcel and office uses on the Dublin parcel. The joint development currently being proposed differs in density and type of land uses from that assumed ~ the DPX EIR. Therefore, BART has prepared this Supplemental EIR in order to supplement, where necessary, the environmental analysis included in the DPX EIR. ,...... I This Supplemental EIR has been prepared by BART, as the lead agency in compliance with the California Environmental Quality Act of 1970 (CEQA) (Public Resources Code ~21000,et seq.) and the State CEQA Guidelines (California Code of Regulations ~15000, et seq.), as amended. An EIR is a full dIsclosure, public information document in which the significant environmental impacts of a proposed project are evaluated; measures to mitigate significant impacts are identified, when feasible; and alternatives to the project that can reduce or avoid significant environmental effects are evaluated. A Supplemental EIR is prepared when an EIR has already been prepared for a project and only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed situation. Section 15163 of the State CEQA Guidelines describes the Supplemental EIR process as follows: ........' , . , r I; r. ! ...... ,f ~ fl , San Francisco Boy Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village 1-1 EDAW Introduction (a) (b) (c) (d) (e) The Lead or Responsible Agency may choose to prepare a supplement to an ElR rather than a subsequent ElR if: Any of the conditions described in ~ 15162 (presence of new impacts or impacts not previously considered) would require the preparation of a subsequent EIR, and Only minor additions or changes would be necessary to make the previous EIR adequately apply to the project in the changed simation. The supplement to the ElR need contain only the information necessary to make the previous EIR adequate for the project as revised. (1) (2) A supplement to an EIR shall be given the same kind of notice and public review as is given to a draft EIR under Section 15087. A supplement to an EIR may be circulated by itself without recirculating the previous draft or fmal ElR. When the agency decides whether to approve the project, the decision-making body shall consider the previous EIR as revised by the supplemental EIR. A fmding under Section 15091 shall be made for each significant effect shown in the previous EIR as revised. An ElR is an informational document used in the planning and decision-making process by the lead agency (i.e., BART) and all responsible agencies. CEQA Guidelines defme the ''Lead Agency" as the public agency with principal responsibility for carrying out or approving a project. The term "Responsible Agency" includes all public agencies, other than the Lead Agency, that have discretionary approval power over aspects of the project. The purpose of an EIR is not to recommend either approval or denial of a project; its purpose is to disclose objective information so that informed decisions can be made. CEQA requires the decision-makers to balance the benefits of a proposed project against its unavoidable environmental effects in deciding whether to carry out a project. Mter reviewing the DPX EIR, this Supplemental EIR, and the project proposal, BART will decide, through a majority vote in a public hearing, whether to approve, approve with modifications, or deny the transit village uses (the BART station was previously approved by the BART Board). The identification of environmental impacts as significant and unavoidable does not mean a project must be denied; BART may still approve the project if it believes that economic, legal, social, technological or other benefits outweigh the significant unavoidable impacts. If BART decides to approve the project, the District would make CEQA-mandated "fmdings" with respect to each significant environmental effect, pursuant to PRC ~21081(a). If feasible mitigation measures or alternatives must be incorporated into the project to mitigate or avoid significant environmental effects. If such mitigation measures or alternatives are infeasible, BART must fmd that specific overriding benefits of EDAW Introduction 1-2 San Francisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village /10 .. .'

BART also intends for this Supplemental ErR, combined with the DPX ErR, to serve as the CEQA- required environmental documentation for consideration of this project by other Responsible Agencies, including, but not limited to, the City of Dublin, the City of Pleasant on, the California Regional Water Quality Control Board and the California Department of Transportation. 1.2 SCOPE OF THE SUPPLEMENTAL EIR ,..... BART submitted the Notice of Preparation (NOP) of this ErR to the California Office of Planning and Research onAprilll, 2000,~or distribution to int~rested~tate~gencies and mailed the NOP to other potentially responsible agencies and interested parties. The NOP is a CEQA-required brief notice sent by the Lead Agency to notify Responsible and Trustee Agencies, that the Lead Agency plans to prepare an ErR and solicits guidance regarding EIR scope and content. Upon distribution of the NOP, which included an Initial Study that was prepared to identify potential project environmental issues, a 30-day comment period began. The NOP and the comments received are found in Appendix A. .r \ On May 4,2000, BART held an ErR scoping meeting for the proposed project at the City of Dublin's Council Chambers. The intent of the scoping meeting was to provide the public with an opportunity to identify issues that should be evaluated in the draft Supplemental ErR. Written comments received during this scoping meeting are included in Appendix A. Based upon an understanding of the project, the. commeIlts. .received on the NOP, and the public scoping meeting, BART has determined that the proposed project has the potential to result in significant or potentially significant impacts in the following environmental issue areas, which are L...... ,', ,..,...._" _,.:" .

This Supplemental ErR includes a detailed evaluation of the impacts on these resources, with relevant .' information from the DPX ErR summarized, where appropriate. The DPX ErR identified environmental effects that wotild not be considered significant. This Supplemental EIR need not address in detail effects found not to be significant. A brief explanation is provided below, as supported by the DPX ErR and the Initial Study prepared for this project, indicating the reasons why the following effects were determined not to be significant, as required by State CEQA Guidelines ~15128. Agricultural Resources. The project site is not located on Prime Farmland, Unique Farmland, or Farmland of Statewide Importance, as identified by the Farmland Mapping and Monitoring Program of the California Resources Agency. Also, the project site has not been used for agricultural production within the recent past and is completely isolated from agrictiltural areas within the region. Therefore, the proposed project wotild have no effect on agrictiltural resources. Earth Resources. The DPX ErR identified and evaluated the earth resource impacts that wotild be anticipated with development of the project site, including seismic shaking, surface fatilt rupture, and ground failure. The DPX EIR concluded that the potential effects on the project site associated with earthquakes and fatilt offset or rupture wotild be considered significant. In order to minimize these potential impacts, detailed mitigation measures were included in the DPX EIR. These measures included the following: . The potential impact of groundshaking wotild be mitigated by structural and foundation design incorporated into the [mal engineering design. Design standards wotild be specified to withstand groundshaking of O.62g. Depending upon the degree of conservatism adopted, the design features may include bracing and/or guying systems to minimize swaying of support columns, and extra heavy-duty connections between the support columns and the support beams. The potential for liquefaction can be mitigated by extending the base of each support pier down to a non-liquefiable material, by removing soft zones in the upper soil profile, and by monitoring for EDAW Introduction 1-4 Son Froncisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village ~ .. iii 'jI III .

Additional subsurface investigation would be required for major structures, such as overheads. Dewatering and temporary . support of excavations may be needed. All final design standards and features would be included in a mitigation monitoring plan for the project. . The station at West DublinjPleasanton could be placed on piles to protect it from liquefaction, or the alluvium could be densified by grouting or dynamic deep compaction. The foundations for any overhead structures could be extended down into a non-liquefiable geologic horizon. These design recommendations would be considered duriIlg fmal engiIleering. l'he ])P:x~IR. evaluated the earth resource impacts that would be anticipated with joint development of theW est DublinjPleasanton Station. The D PX EIR concluded that the commercial, residential and parking structures associated with joint development would be subjected to the same geologic hazards identified for the station sites (DPX Draft EIR, pg. 5-49). The DPX EIR assuined that with implementation of the mitigation measures identified above, the earth resource impacts associated with joint development of the West DublinjPleasanton Station would be reduced to a less-than-significant level. Because the development proposed with the proposed project would not differ substantially from the joint development evaluated in the DPX EIR, the earth resource impacts of the proposed project remain less than significant with implementation of the above identified mitigation measures. Therefore, no additional analysis of earth resource impacts is necessary in the EIR. Mineral Resources. The project site is not located in an area of aggregate resources (Pleasanton General Plan,'p. VII-26). Therefore, the project would have no effect on mineral resources of value to the region. Recreation. Numerous existing recreation facilities exist within the vicinity of the proposed project. Within the City of Dublin, recreation facilities in close proximity to the proposed project site include Mape Memorial Park, Dolan Park, and Shannon Park. Within the City of Pleasanton, recreation facilities in close proximity to the project site include Moller Park, Muirwood Park, and Pleasanton Ridge Regional Park. In addition, numerous gymnasiums and sports fields exist within the project area, iIlcludiIlg the Dub1i.i1 Sports Grounds, located at the intersection of Dublin Boulevard and Civic Plaza, which has existing facilities for baseball, softball, soccer, and nature walks. Although the residential component of the proposed project could result in an increase in the use of these neighborhood, community, and regional parks, it is not expected that future residents would utilize these facilities such thats'::lbst~I1.tialphysical deterioration of the facilities would occur. San Frandsco Bay Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village 1-5 EDAW Introduction 1.3 TERMINOLOGY USED IN THE SUPPLEMENTAL EIR ) l~l .. . The Supplemental ErR includes the following terminology to denote the significance of environmental .. impacts of the proposed project: ~ Less-than-Significant Impact: A less-than-significant impact is one that would not result in a substantial and adverse change in the environment. This impact level does not require mitigation measures. ~ Significant Impact: CEQA Guidelines ~15382 defmes a significant impact as a substantial adverse change in any of the physical conditions within the area affected by the project. Levels of significance can vary by project, based on the change in the existing physical condition and the substantial body of opinion that considers the effect to be adverse. The Initial Study checklist included in Appendix G of the State CEQA Guidelines provides additional guidance regarding impacts that would normally be regarded as having a significant effect on the environment. This Supplemental ErR uses the CEQA definition of significant impacts. Mitigation measures or alternatives to the proposed project must be provided in an attempt to reduce the magnitude of significant impacts to less-than-significant levels. ~ Potentially Significant Impact: A potentially significant impact is one that, if it were to occur, would be considered a significant impact as described above; however, the occurrence of the impact cannot be immediately determined. For example, while the EIR may provide evidence that buried archaeological resources could be found in a particular location, the actual discovery cannot be determined until the time of project construction. For CEQA purposes, a potentially significant impact is treated as if it were a significant impact (i.e., mitigation is developed when feasible). ~ Significant and Unavoidable Impact: A significant and unavoidable impact is one that would result in a substantial adverse effect on the environment, but could not be mitigated to a less-than-significant level. A project could still proceed with significant unavoidable impacts, but BART would then be required to prepare a Statement of Overriding Considerations (see discussion in Section 1.1) ~ Threshold of Significance: A criterion established by the lead agency to defme at what level an impact would be considered significant; i.e.) if an impact exceeds a threshold, it would be considered significant. A criterion is defined by a lead agency based on EDAW Introduction 1-6 Son Francisco Boy Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village .

State CEQA Guidelines ~15370 defmes mitigation as: a. avoiding the impact altogether by not taking a certain action or parts of an action; b. minimizing impacts by 1.iill.itiIlg the degree or magnitlideof the;ction';rld its implementation; c. rectifying the impact by repairing, rehabilitating, or restoring the affected environment; d. reducing or eliminating the impact over time by preservation and maintenance operatioI1S during the life of the action; and e. compensating for the impact by replacing or providing substitute resources or environments. 1.4 SUPPLEMENTAL EIR ORGANIZATION This Supplemental EIR is organized into chapters, as identified and briefly described below.

As stated in the State CEQA Guidelines ~15123(a), "[a]n EIR shall contain a brief summary of the proposed actions and its consequences. The language of the summary should be as clear and simple as reasonably practical." State CEQA Guidelines ~15123(b) states, "[t]he summary shall identify: (1) Each significant effect with proposed mitigation measures and alternatives that would reduce or avoid that effect; (2) Areas of controversy known to the Lead Agency, including issues raised by agencies and the public; and (3) Issues to be resolve~, including the choice among alternatives and whether or how to mitigate the significant effects." Accordillgly, thiS summary includes a brief synopsis of the proposed project and project alternatives, environmental impacts and mitigation, areas of known controversy, and issues to be resolved in the environmental impact report (EIR). Table 2-1 (at the end of this section) presents the summary of potential environmental impacts, their level of significance without mitigation measures, mitigation measures, and levels of significance with mitigation measures. r f t 2.2 SUMMARY OF PROJECT DESCRIPTION The proposed project\Vould include development of the San Francisco Bay Area Rapid Transit District (BART) West DublinfPleasanton Station; a 17-acre transit village that would include a mix of residential, office and hotel uses; parking facilities for the BART station and the transit village uses; and . a bus intermodal facility. The BART station would be located in the median ofI-580. Office uses would be located adjacent to and south of the station in Pleasanton; hotel, residential uses, and the bus facility would be adjacent to and north of the station in Dublin. 2.3 DISCRETIONARY ACTIONS AND PROJECT ApPROVALS BART has the primary approval authority over the proposed transit village uses (the BART station was previously approved by the BART Board). The Supplemental EIR is to be certified by the BART ~.- - -'" - .....,..,,--, .. "" , Board of Directors prior to the Board taking action on the proposed transit village uses. Following certification of the Supplemental EIR, the transit village uses will be considered for approval, conditional approval, or deriial by the Board. This Supplemental EIR is also rntended to be used by responsible agencies that may have some ~ther authority over the project. Responsible agencies for this project include the California Department of r f I ! Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and T ronsit Village 2-1 EDAW Executive SUl1]ffiory Il~ "" . ;~'I Transportation, the City of Dublin, and the City of Pleasanton. Approval of the proposed project .- would require, at a minimum, the following discretionary actions from responsible agencies: ~ Issuance of an encroachment permit by the California Department of Transportation in order to construct the pedestrian bridges over Interstate 580 that would connect both parcels to the BART station, as well as for construction of the BART station in the median ofInterstate 580. ~ Approval of a Planned Development Zoning District Stage 1 Development Plan and a Tentative Map by the City of Dublin. f ~ z.. ;> [:) Approval of the West Dublin BART Specific Plan and conforming amendments to the Dublin General Plan, Downtown Specific Plan and Zoning Ordinance. ~ ~ Approval of a new Planned Unit Development and Tentative Map by the City of Pleasanton. -.

The purpose of the NOP was to solicit comments from public agencies on issues germane to that agency that should be considered in the draft Supplemental EIR. The public review period for the NOP ended 30 days after public distribution of the NOP. All of the issues raised in the NOP comment letters (Appendix A) have been addressed in the draft Supplemental EIR. No apparent significant areas of controversy have been identified in these letters. 2.5 SUMMARY OF ENVIRONMENTAL CERTIFICATION PROCESS BART, in its review of the proposed project and determination for action, will consider the entire environmental assessment contained in this Supplemental EIR. Upon completion of the environmental review process, BART will have the option to certify that the fmal Supplemental EIR: 1) has been completed in compliance with CEQA; 2) was presented to the decision-making body of the Lead Agency (i.e., the BART Board of Directors ), which reviewed and considered the information contained in the fmal Supplemental EIR prior to approving the project; and 3) reflects the lead agency's EDAW Executive Summary 2-2 San Francisco Bay Area Rapid Transit District West Dublin/Pleasonton BART Station and Transit Village . .. . d "" ,~ . r. .. ~ . .. .. .. .

If the Supplemental EIRis certified, BART will determine in a separate action whether the proposed transit village uses will be denied, approved, or conditionally approved. ~ .~ 2.6 SUMMARY OF ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES .,...., Chapter 4 of this Supplemental ErR describes in detail the environmental impacts that would result t t from implementation of the proposed project. Cumulative and growth-inducing impacts of the proposed project are discussed in Chapter 6 of this Supplemental EIR. A summary description of the environmental impacts, mitigation measures, and level of significance after mitigation is presented in Table 2-1, at the end of this chapter. r r- I""'" J ., t"""' t r 2.7 PROJECT ALTERNATIVES Section 15126(d) of the State CEQA Guidelines, as amended, mandates that all ErRs include a comparative evaluation of the proposed project with alternatives to the project that are capable of attaining most of the project's basic objectives but would avoid or substantially lessen any of the significant effects of the project. CEQA requires an evaluation of a "reasonable range" of alternatives, including the "no project" alternative. Section 5 (Alternatives to the Proposed Project) of this.EIR provides an analysis of the c{)mparative impacts anticipated from four alternatives to the proposed project and associated mitigation measures: 1) the no-project alternative, consisting of construction of the approved West DublinjPleasanton BART station with associated parking but no transit village uses; 2) a different-use alternative, consisting of office uses in place of proposed residential uses on the Dublin parcel; 3) a Dublin reduced-density alternative, consisting of a 38 percent reduction in the number of hotel beds and a 13 percent increase in the number of residential units on the Dublin parcel with no changes on the Pleasanton parcel; and 4) a Pleasanton reduced-density alternative with the elimination of office development on the Pleasanton parcel and no change on the Dublin parcel. 2.8 SIGNIFICANT AND UNAVOIDABLE ENVIRONMENTAL IMPACTS Section 4 of this Supplemental EIR provides a description of the potential environmental effects of the proposed project, as well as proposed measures to mitigate project effects to the extent feasible. Section 6 provides a discussion of cumulative impacts. Mter implementation of the proposed mitigation measures, the majority of the adverse effects associated with the proposed project would be reduced to a less-than-significant level. The following impacts, however, would remain as significant and Son Francisco Boy Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village 2-3 EDAW Executive Summary unavoidable adverse impacts of the proposed project after implementation of the identified mitigation measures. CONSTRUCTION NOISE If construction activities occur on the Dublin parcel following occupation of either the hotel or residential buildings, the noise levels would likely exceed 80 dBA and would result in an increase of greater than 3 dBA over existing conditions. Because mitigation measures would not significantly reduce these noise levels, this potential noise impact would remain significant and unavoidable. OPERATIONAL NOISE LEVELS The expected exterior noise levels at the proposed hotel on the Dublin parcel would exceed acceptable levels identified in the City of Dublin's General Plan. Because feasible mitigation measures are not available to reduce these existing noise levels to less-than-significant levels, this impact would remain significant and unavoidable. CUMULATIVE TRAFnc IMPACTS Following implementation of the identified mItigation measures, significant and unavoidable cumulative traffic impacts would be anticipated at the intersections of 1-680 Southbound RampsjStoneridge Drive (No. 346),1-680 Northbound RampsjStoneridge Drive (No. 347), and Johnson DrivejStoneridge Drive (No. 348) if the West Las Positas interchange is not constructed.

The proposed project would include a residential complex, a hotel, and associated parking facilities on the Dublin parcel in an area surrounded by commercial and office uses as well as the Cor-O-Van warehouse building. These surrounding uses only operate during the day and, thus, would not be expected to generate noise or traffic during the nighttime hours that could disrupt residents and hotel guests (Noise is evaluated separately in Section 4.3). There is no direct access to the warehouse building through the site. In addition, the proposed design for the residential complex is focused toward Golden Gate Drive with parking located to the rear in order to provide a pedestrian orientation within a commercially-developed area. Therefore, the proposed project would have a less-than- significant land use compatibility impact related to development on the Dublin parcel. No mitigation measures are necessary. 4.1-2: Compatibility with Surrounding Land Uses Pleasanton Parcel. Land uses surrounding the parcel include office buildings to the west and east and the Stoneridge Mall and associated parking facilities to the south. Development of the proposed project would be consistent with these surrounding land uses. Therefore, no impacts related to compatibility with surrounding land uses would be anticipated. No mitigation measures are necessary. 4.1-3: Consistency with General Plan - City of Dublin. The proposed hotel and residential uses would be inconsistent with the current Public/Semi-Public land use designation and the Light Industrial and Regional Page 2-5 West Dublin/Pleasanton BART Station and Transit Village Table 2-1 EXECUTIVE SUMMARY Impact Level of Significance with Mitigation Mitigation Measure Commercial zoning designations for the site. These inconsistencies with existing land use plans would be removed if the proposed West Dublin BART Specific Plan and related changes to the City of Dublin General Plan, Downtown Core Specific Plan, and zoning designation of the project site are adopted as proposed. If the proposed West Dublin BART Specific Plan is not adopted, the Dublin General Plan, Downtown Core Specific Plan and zoning designation for the site must be amended to accommodate the residential and hotel uses. In either case, the residential and hotel uses shall not be constructed on the Dublin parcel until these changes to existing land use requirements have been adopted. Accordingly, this impact would be less than significant. LESS THAN SIGNIFICANT No mitigation measures are necessary. 4.1-4: Consistency with General Plan - City of Pleasanton. The Retail/Highway/ Service Commercial, Business and Professional Offices land use designation for the Pleasanton parcel was designed specifically for commercial and office type development near major highway centers. Therefore, the proposed project would be consistent with this land use designation.

Construction activities and operational site uses associated with the project could result in degradation of water quality in nearby surface water bodies and groundwater reservoirs by reducing the quality of stormwater runoff. This would be considered a significant In addition, a Stormwater Pollution Prevention (SWPPP) shall be developed and implemented proposed project site. An SWPPP should include Best Management Practices (BMPs) designed to reduce potential impacts to surface water quality through the construction and life of the project. An SWPPP shall be prepared such that, when properly implemented, it will reduce or eliminate impacts to surface water quality from all phases of the project. Required elements of the SWPPP include Plan for the impact. Construction Stormwater Manaeement Controls. These controls shall include practices to minimize the contact of construction materials, equipment, and maintenance supplies (e.g., fuels, lubricants, paints, solvents, adhesives) with stormwater. The SWPPP shall specify properly designed centralized storage areas that keep these materials out of the rain. - ~I Executive Summary Page 2-7 Dublin/Pleasanton BART Station and Transit Village West Table 2-1 EXECUTIVE SUMMARY Level of Significance with Mitigation Mitigation Measure An important component of the stormwater quality protection effort is knowledge of the site supervisors and workers. To educate on-site personnel and maintain awareness of the importance of stormwater quality protection, site supervisors shall conduct regular tailgate meetings to discuss pollution prevention. The frequency of the meetings and required personnel attendance shall be specified in the SWPPP. The SWPPP shall specify a monitoring program to be implemented by the construction site supervisor, and must include both dry and wet weather inspections. City of Dublin and City of Pleasanton personnel will conduct regular inspections to ensure compliance with the SWPPP (this is already standard procedure). Erosion and Sediment Control. BMPs designed to reduce erosion of exposed soil may include, but are not limited to: soil stabilization controls, watering for dust control, perimeter silt fences, placement of hay bales, and sediment basins. The potential for erosion is generally increased if grading is performed during the rainy season as disturbed soil can be exposed to rainfall and storm runoff. If grading must be conducted during the rainy season, the primary BMPs selected shall focus on erosion control to keep sediment on the slopes. End-of-pipe sediment control measures (e.g., basins and traps) shall be used only as secondary measures.

Project plans shall incorporate, if appropriate, catch basin inserts and filters along with cleaning schedules. LESS THAN SIGNIFICANT No mitigation measures are necessary. 4.2..3: Flooding. The project site is not located within a 100-year or 500-year flood hazard area, as delineated in the general plans for Dublin and Pleasanton. However, within the vicinity of the proposed project, the 100-year and 500- year flood hazard zones extend east ofI-680 pastHopyard Road. These flood hazard areas are located downstream of Dublin Creek and runoff from construction or operational activities on the project site could contribute to downstream flooding. However, this contribution would not be substantial given the relatively small total area of the site when compared to the overall drainage area of the region. This would be considered a less-than-significant impact. LESS THAN SIGNIFICANT No mitigation measures are necessary. 4.2-4: General Plan Consistency - City of Dublin, City of Pleasanton. Development of the proposed r;>roject would result in changes to surface water runoff volumes and quality. Through City grading permit processes, the proposed project would be subject to site-specific review and conditions imposed by the cities, which would be expected to reduce these effects. In addition, this EIR provides mitigation measures to reduce impacts associated with water quality impacts to a less-than-significant level (see Mitigation Measure 4.2-2). With normal City permit processing procedures and ErR mitigation, the proposed project would - (\J U\ Executive Summary Page 2.9 Dublin/Pleasanton BART Station and Transit Village West Table 2-1 EXECUTIVE SUMMARY Level of Significance with Mitigation Mitigation Measure Impact be consistent with water quality policies and programs outlined in the City of Dublin General Plan and the City of Pleasanton General Plan.

Impact 4.3-2: Increases in Area and Stationary Source Noise. On-site area and stationary sources of noise associated with the proposed land uses would result in only minor and intermittent increases in ambient noise levels, which would occur primarily during the day and evening hours and less frequently at night. Noticeable increases in ambient noise levels (Le., 3 dBA, or greater) at nearby noise-sensitive receptors are not anticipated. Therefore, this impact would be considered less than significant. LESS THAN SIGNIFICANT No mitigation measures are necessary. 4.3-3: Increases in Traffic Noise Levels on Area Roadways. The project generated traffic would not result in a noticeable increase (Le., 3 dBA, or greater) in traffic noise levels at any existing noise-sensitive receptors. Therefore, this impact would be considered less than significant. SIGNIFICANT AND UNAVOIDABLE The developer shall utilize an acoustical professional, such as a Licensed Engineer or Licensed Architect with experience in acoustics. The acoustician shall develop noise attenuation measures to be incorporated into the design and construction of the proposed residential, hotel, and office building that will produce a composite building sound transmission control (STC) rating of 30 (or higher) individually computed for the walls and for the floor/ceiling construction. Suggested measures include: wall construction with resilient channels, staggered studs, or double-stud walls, use of dual glazed windows with laminated glass, limitation of the number and size of windows along walls located within close proximity to major noise sources, and ensuring that all exterior construction joints are either grouted or caulked air-tight. Additional measures include locating on-site stationary noise sources (Le., heating and air conditioning units, emergency-use generators, building mechanical equipment, 4.3-4: Compatibility of the Proposed Land Uses with Projected On-site Noise Levels. Projected noise levels at the Dublin and Pleasanton parcels would exceed the "normally acceptable" thresholds established by each respective jurisdiction for the proposed land uses.

Title 24 of the California Code of Regulations requires the preparation of an acoustical analysis for multi-family residences that demonstrates how interior noise levels will achieve a 45 dBA CNELlLdn, where the exterior noise levels exceed 60 dBA CNELlLdn. As a result, a Title 24 analysis shall be prepared as part of the final design of the proposed residential dwellings. To the extent necessary, noise control measures shall be designed according to the type of building construction and specified sound rating for each building element to achieve an interior noise level of 45 dBA CNELlLdn.

Occupation of the proposed project would increase CO concentrations at nearby intersections due to increased vehicular traffic to and from the project site. However, predicted CO concentrations at affected intersections would not exceed state or federal ambient air quality standards. this is considered a less-than-significant impact. No mitigation measures are necessary. Therefore, 4.4-3: Localized CO Concentrations-Proposed Parking Structures. Operation of the proposed project would result in CO concentrations within the proposed parking garages. However, projected CO concentrations would not exceed applicable thresholds. As a result, this impact would be less than significant. No mitigation measures are necessary. 4.4-4: Regional Air Quality Impact. The proposed project would generate regional emissions primarily associated with increased vehicle use related to the transit village uses. Additional emissions associated with the use of natural gas- fired appliances,landscape maintenance equipment, and consumer products would also be generated. However, approval of the proposed project would facilitate construction of the approved West Dublin/Pleasanton BART Station. The use of this new BART Station would substantially reduce automobile travel on the local roadway network by providing a public transportation option for commuters. The result would be a net reduction in regional emissions. Therefore, this impact would be considered less than significant. No mitigation measures are necessary. 4.4-5 Consistency with the BAAQMD Clean Air Plan.

This measure would improve the intersection operations from LOS F to LOS C. 4.5.1 City of Dublin Intersections. Existing Plus Approved Projects Plus Project Scenario. Under the Existing plus Approved Projects plus Project scenario, two intersections would operate unacceptably. These intersections include Dublin BoulevardlDougherty Road and St. Patrick Way/Golden Gate Drive. However, the proposed project would actually improve the level of service at the Dublin BoulevardlDougherty Road intersection from LOS F to LOS E. Therefore, the proposed project would not significantly affect this intersection. With the project's contribution to the St. Patrick Way/Golden Gate Drive intersection, the intersection would operate at LOS F during the p.m. peak hour. This would be considered a significant project impact.

With this improvement, the intersection would operate acceptably at LOS C with and without the West Las Positas interchange. 4.5-3 City of Pleasanton Intersections - Existing Plus Approved Projects Plus Project Scenario. Under the Existing plus Approved Projects plus Project scenario without the West Las Positas interchange, three intersections would operate unacceptably. These intersections include Hopyard Road/Stoneridge Drive (No. 313), Stoneridge Mall Road/Stoneridge Drive (No. 345), and 1-680 Southbound Ramps/Stoneridge Drive (No. 346). With the implementation of planned future improvements and anticipated City improvements, the Hopyard Road/Stoneridge Drive and 1-680 Southbound Ramps/Stoneridge Drive intersections would operate acceptably. However, the Stoneridge Mall Road/Stoneridge Drive intersection would continue to operate unacceptably with the contribution of project traffic. With the construction of the West Las Positas interchange, this intersection would continue to operate unacceptably with the contribution of project traffic. The unacceptable operation of this intersection would be considered a significant traffic impact. LESS THAN SIGNIFICANT The following measures are required to improve access to the Pleasanton parcel To improve traffic operating conditions at the shared project driveway, the intersection shall be signalized. An eastbound left turn lane into the driveway shall be striped on Stoneridge Mall Road. A westbound left- turn lane already exists into the Nordstrom driveway. ~ 4.5-4 Pleasanton Parcel Access and Circulation. Access to the Pleasanton parcel would be from two driveways located on Stoneridge Mall Road.

Measures shall be implemented to improve traffic operating conditions along the project frontage on Stoneridge Mall Road associated with the intersection signalization. Due to the proximity of the Nordstrom parking lot driveways to the proposed signal, vehicles turning left from the parking lot could be a hazard to vehicles traveling on Stoneridge Mall Drive. Two options have been identified to address this concern. The first option would restrict access along the northern boundary of the Nordstrom parking lot by constructing a barrier (e.g., a concrete planter) generally between the shared driveway and the BART Station driveway. This would require the reconfiguration of the Nordstrom parking lot and the removal of approximately 12 parking spaces. The second option would include constructing a concrete median within Stoneridge Mall Road, also generally between the shared driveway and the BART Station driveway. Because adequate storage area would not be available on Stoneridge Mall Road for vehicles turning left from the BART Station driveway and excessive vehicle stacking within the driveway could occur with this option, the BART Station driveway would be restricted to right turn in, right turn out only. The project applicant shall coordinate with the City of Pleasanton to implement one of these improvement options to ensure the safe, efficient operation of this intersection. ~ -- ~ The BART Station driveway shall accommodate one entry lane and two exit lanes.

BART will conduct the monitoring program, which will consist of: A baseline survey of parking conditions in the vicinity of the West DublinlPleasanton BART Station prior to the commencement of operations at the station. The baseline survey will establish parking conditions in the vicinity of the station during weekday morning hours. ~ Monitoring during the first six months of operation of the station to verify if spillover parking is occurring within a quarter mile radius of the station. Such monitoring will be based on field surveys and any complaints received by BART and local parking authorities. In addition, under-utilization of the BART parking garages will be monitored to determine whether any increase in the use of adjacent private parking is related to a disincentive to use BART parking due to parking charges. (After the first six months of operation of the station, BART Community Relations staff will respond to parking complaints and BART will investigate such complaints to verify parking concerns.) ~ 4.5.5 Dublin and Pleasanton Parki~g Supply and Demand. The hotel and residential components in Dublin would have a surplus of 37 spaces for the hotel and 156 spaces for the residential use during the peak parking hour. The office component in Pleasanton is estimated to have a surplus of 157 spaces during the peak parking hour. The parking demand for the West Dublin/Pleasanton BART Station would be accommodated entirely by the proposed BART parking facilities. No deficit in parking spaces would be anticipated. Therefore, the project's parking demand would be considered a less-than-significant impact. However, if BART implements a parking charge program, spillover parking onto adjacent lots may occur. This would be considered a significant impact. If spillover parking is identified as a problem, BART will assist local parking authorities in implementing appropriate parking control measures.

The proposed project would generate approximately 66,500 gpd of . wastewater. The DSRSD wastewater treatment facility in Pleasanton is currently expanding its operations to . accommodate a final capacity of 17 mgd in the year 2003. Since current flows to the plant are only averaging 10 mgd (for 1999), the plant will have adequate capacity to serve the proposed project. The proposed project's effects on wastewater treatment capacity would be considered less than significant. 4.6.4d: Adequacy of Export Capabilities. The proposed project would generate new wastewater flow demand on the existing LA VWMA wastewater conveyance facilities. The LA VWMA export pipeline is currently operating at 100% of capacity. However, the export pipeline is currently being expanded to meet project demands. With the proposed expansion, the proposed project's effects on LA VWMA wastewater conveyance facilities would be considered less than significant. 4.6.4e: General Plan Consistency. City of Dublin, City of Pleasanton. The Dublin General Plan and the Pleasanton General Plan both contain policies to ensure that future developments in their respective cities are served by adequate wastewater treatment and export services. Both DSRSD and LA VWMA are currently expanding their facilities to provide the additional capacity necessary to serve planned developments within the cities of Dublin and Pleasanton.

Because a new elementary school is opening in the Fall of 2000 and a new middle school is anticipated to open in the Fall of 2004, the DUSD would have sufficient capacity to serve the students generated by the proposed project. No significant school facility impacts would be anticipated. PUBLIC HEALTH and SAFETY (Section 4.7) LESS THAN SIGNIFICANT In order to determine the extent of soil and groundwater contamination on the site, field sampling prior to the commencement of construction activities shall be conducted. This sampling shall be consistent with the field sampling for the project site outlined in the Field Investigation Work Plan prepared for the DPX Project (Bechtel Environmental, Inc., 1991) and shall consist of soil borings and groundwater monitoring wells located throughout the project site. In addition, a Health and Safety Plan shall be developed that outlines safety procedures to follow in the event of accidental spills or the unearthing of contaminated soil or groundwater during construction activities. This Health and Safety Plan shall also be consistent with the safety guidelines set forth in the Field Investigation Work Plan. 4.7 -1: Potential Human Exposure to Soil Contaminants. The proposed project would be located within an area that has numerous reported incidents of hazardous materials contamination. Project construction could potentially expose construction workers and sensitive receptors to hazardous materials in the area.

Both parcels are owned by BART. 3.1 PROJECT LOCATION AND SETTING REGIONAL SETTING' The proposed project is located within the cities of Dublin and Pleasanton, approximately 30 miles east of San Francisco and approximately 8 miles west of Livermore. Dublin and Pleasanton are both located withiIltlle southern.A.lamecla COunty portion of the '''Td-Valley'' area. The Tri-Valley area includes the town of Danville, the citiesofbublin, Pleasanton, Livermore and San Ramon, and unincorporated portions of Alameda and Contra Costa Counties. Dublin and Pleasanton are both bordered to the west by ridgelands that separate the San Francisco Bay Area from the Tri- Valley area (Exhibit 3-1). To the east, Dublin is bordered by the Camp Parks Military Reservation and the Dougherty Hills, while Pleasanton is bOUIld byhills to th~.s~uth~ast."Tht~b'<lIl~re~sc,fb(,thcities are predominately lc,cated on the flat valley floor. Regional access is provided by Interstate 580 (1-580), which forms the southern boundary of Dublin and the northern boundary for Pleasanton, and Interstate 680 (1-680), which generally bisects the cities along a north-south axis. LOCAL SETTING The project site is located. on 17:1 acres that encompass two parcels and a portion of the median of Interstate 580 (Exhibits 3-2 and 3-3). The site is located approximately 0.2 mile west of 1-680 and approximately 0.3 mile east of FoothilljSan Ramon Road. The northern 9.75-acre parcel, located within the City of Dublin, is identified on the United States Geological Service (USGS) topographic map as containing a drive-in theater, although the site contains no buildings and has been empty for years.

" The Dublin parcel is surrounded by chain link fencing and includes short grasses and shrubs over most of the site. Large portions of the parcel have been disturbed by prior site uses (e.g., construction staging, Christmas tree lot). Dublin Creek abuts the ''L-shaped'' Dublin parcel to the south, while a large warehouse owned by Cor-O- Van forms the western site boundary. A truck parking area used for Cor-O- V an trailers forms the northern boundary of the Dublin parcel with an office building occupied by Washington Mutual further to the north. The eastern portion of the Dublin parcel is paralleled by Golden Gate Road, the Golden Gate Business Park, and the Enea Retail Plaza. Local access to the Dublin parcel is provided by Golden Gate Road. r ~ I ~. The 7.35,.-acre Pleasanton parcel includes non-native grasses and dense areas of ornamental trees dominated by black locusts. The parcel is bordered to the north by 1-580 with the remainder of the site surrounded by parking areas for Stoneridge Mall to the south and adjacent office buildings to the east and west. Local access to the Pleasanton parcel is provided by Stoneridge Mall Road. Utility connections are present throughout both parcels including numerous electrical conduit boxes, water valves, and fire hydrants. The Pleasanton parcel also includes a BART electrical substation that provides electricity to BART's operating line. The project site is located within the Dublin Creek watershed. Dublin Creek conveys runoff from the hills to the west and flows east, paralleling the Dublin parcel's southern boundary and Interstate 580. The creek continues east and then south flowing into Arroyo de la Laguna, Alameda Creek and eventually into the San Francisco Bay. This creek has been charmelized through much of the local area. 3.2 PROJECT CHARACTERISTICS r-i , . The proposed project includes several elements, including the completion of construction of the West Dublin/Pleasanton BART Station approved by the BART Board of Direct~rs as part of the DublinjPleasanton Extension Project (DPX) on February 8,1990. On the Dublin parcel, a 240-room, eight-story hotel and 160-unit, four-story residential buildings are proposed to be constructed. The hotel is proposed to be located closest to the freeway with 251 parking spaces, of which 71 would be accommodated as shared parking within the BART parking garage. The residential portion of the development is proposed to be located furthest from the freeway and would include 297 parking spaces, some located at the surface level and some at the one-half level under the residential buildings. In addition, a 713-stall, six-story parking garage for BART patrons is proposed to be constructed on the eastern portion of this parcel. A pedestrian overcrossmg wollld connect the BART parking garage to the BART station. .. An intermodal transfer station is proposed to be incorporated into the parking garage and would include eight bus stalls for public transit transfers to the BART station. r t Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 3-5 EDAW Project Description The proposed shared parking between the hotel and BART parking garage would optimize the use of available parking spaces. Shared parking is possible because the hotel's peak demand for parking spaces occurs at a different time than the peak demand for parking by BART patrons. BART reserves 10% of its parking spaces for persons arriving after 10:00 a.m. These spaces would be available for use by hotel patrons until 10:00 a.m. Mter 10:00 a.m., these spaces would be vacated by the hotel users and available for BART patrons. An agreement between BART and the hotel developer would be executed outlining the specific shared parking details. Hotel management would most likely be responsible for managing the use of the parking spaces and ensuring they are vacated by 10:00 a.m. This shared parking approach would be consistent with Objective 14.3 of the proposed West Dublin BART Specific Plan, which encourages the use of shared parking among nearby land uses to satisfy parking demand for individual land uses and to reduce the amount of land needed for parking. On the Pleasanton parcel, a 170,000 gross square foot office building with five stories is proposed to be constructed. A total of 560 parking spaces would be provided at grade on the site (3.5 stalls per 1,000 rentable square feet). The office building may include some ancillary retail uses. A 419-stall, five-story parking garage is proposed to be constructed in the northeastern portion of this parcel for the use of BART patrons. One bus stop located on Stoneridge Mall Road would be provided for public transit transfers to the BART station. A pedestrian over crossing would connect the BART parking garage to the BART Station. The BART station area would be located between the east- and westbound lanes of Interstate 580 within the Caltrans median. Foundations for this station were constructed when the line from Castro Valley to East DublinjPleasanton was constructed, limiting the amount of construction activity necessary for the new station. PROPOSED FINANCING STRUCTURE In order to finance the estimated $44 million public portion of the project (i.e., the BART Station with ancillary parking, bus intermodal facility and pedestrian walkways from the station to either side of Interstate 580), a Joint Powers Authority would be created between BART and the Association of Bay Area Governments (ABAG). The Joint Powers Authority would issue bonds for construction of the public facilities. The amount of bonds needed to construct the public facilities would be reduced by the pre-payment of ground rent generated by private use of BART property. Repayment of the bonds would be through a combination of contributions from the cities of Dublin and Pleasanton of tax revenues to be generated from the private development and BART revenues generated by the station and other potential funding sources. Funding of the private development would be implemented with conventional financing and would not involve any BART or other public funds.

In the early 1970s, in an effort to connect outlying communities with business centers, BART initiated a rail system that links Daly City, Richmond, Concord, and Fremont with San Francisco and points in between. The system serves portions of Alameda and Contra Costa counties on the east side of the bay and San Francisco County on the west side. Concurrent with implementation of the original . BART rail system, planning commenced for an extension into the Livermore/Amador Valley. The l)ublilljPleasantonExtenslon, or Dt>X; was proposed to extend along the lnterstate 238 and' 580 corridor through the communities of Castro Valley, Dublin, Pleasanton, and Livermore. The planning for the DPX extension continued into the early 1980s in response to continued growth and land use changes. Numerous studies were completed in concert with extensive community review. These evaluations considered and eliminated from further review various corridors, routes, modes, and station sites, refmed the extension proposal, and ultimatelyiclentifiecl a preferred route. In November 1986, Alameda County voters demonstrated their support to extend BART to eastern Alameda County by approving Measure B. Measure B called for increasing the sales tax: half a percent to provide funding for transportation improvements. One of the specific mandates of Measure B was a rail transit extension from the BART Bay Fair station to DublinjPleasanton. 14. ~ \ ~. In September 1989, a draft EIR was completed that evaluated the bpx Project. The project evaluated in the draft EIR included the 12-mile extension of the existing rail system from the Bay Fair BART Station to the cities of Dublin and Pleasanton. From the Bay Fair station platform, the project alignment was proposed to parallel the existing track southerly to Interstate 238 where it turns east diverging from the BART Fremont line. Following the Interstate 238 corridor, the line was proposed to join the median of Interstate 580 and continue to a station in Castro Valley. From here, the alignment was proposed to extend approximately eight miles through Dublin Canyon to a station in DublinjPleasanton. ., ~ . Five alternatives were evaluated in . the dra.tt EIR: 'illduding no action, a third station in East DublinjPleasanton, East Dublin/Pleasanton as the second station terminus, existing line tie-in design options, and joint development alternatives for the three stations along the extension (Bay Fair, Castro Valley and West DublinjPleasanton). ri . . r- f t The fmal EIR was released in December 1989 and the BART Board of Directors certified the EIR on February 8, 1990. Following certification, the Board adopted the alternative that included a third station in East Dublii1jPleasamon as the project. Following project approval, BART commenced construction of the adopted project. Because of funding constraints, only two of the three approved stations were constructed along the DPX extension (i.e., Castro Valley and East Dublin/Pleasamon).

In an effort to fmance construction of the West Dublin/Pleasanton station, BART released a Request for Proposals to develop the 17-acre area adjacent to the station. Mter completing a competitive proposal process, BART entered into exclusive negotiations with Jo.nes Lang LaSalle on February 25, 1999, to assess the overall fmancial feasibility of a mixed-use development on BART property at the West DublinjPleasanton BART Station. The mixed-use development would include construction of the station and associated transit facilities. This initiated the public/private effort involving BART, Jones Lang LaSalle, and the cities of Dublin and Pleasanton that addressed the following: . DefInition of the private development project, including incorporating a City of Dublin and City of Pleasanton vision for the station area; Review and refmement of all costs and revenues; Assessment of overall project fmancial viability; and Assessment of funding and debt service mechanisms. . . . 3.4 PRO.JECT OB.JECTIVES BART's and Jones Lang LaSalle's objectives for the proposed project include the following: . Create a transit-oriented development that uses the site's unique location along the existing BART line to support public transit uses and reduce single-occupant vehicle trips. . Implement a public-private partnership that combines multiple fInancing sources in order to construct the public portions of the proposed project. These fmancing sources would including long-term leases of BART property, contributions from the cities of Dublin and Pleasanton of tax revenues to be generated from the private development, BART revenues generated by the station, and other potential funding sources. . Develop an intermodal facility that includes both rail and ground transport that supports anticipated transit ridership growth and improves mobility and BART system accessibility along the Interstate 580 corridor. .

The issues evaluated in these sections consist of the significant and potentially significant environmental issue areas identified for review in the Notice of Preparation (NOP), found in Appendix A. These sections are organized into the following major components: Existing Conditions: This subsection presents the eXlstmg regional and local environmental conditions, in accordance with the State CEQA Guidelines ~15125. The "Existing Conditions" subsection describes the baseline conditions against which the environmental impacts associated with the proposed project are assessed. Environmental Impacts: This subsection presents thresholds of significance used in the Draft EIR and discusses potential significant effects on the existing environment associated with the proposed project, in accordance with State CEQA Guidelines ~~15126.2(a) and 15143. The thresholds of significance are presented at the beginning of each subsection. Project impacts are numbered sequentially throughout these sections. That is, impacts in Section 4.2 are numbered 4.2-1, 4.2-2, 4.2-3, ete. Impacts identified in Section 4.3 are numbered 4.3-1, 4.3-2, and so on. A bold font impact statement precedes the discussion of each impact and provides a summary of each impact and its level of significance. The discussion that follows the impact statement includes the substantial evidence upon which a conclusion is made as to whether the impact would be significant or less than significant. A discussion of cumulative impacts is provided in Chapter 6, Cumulative and Growth-Inducing Impacts. Miti~ation Measures: This subsection provides mitigation measures to reduce potentially significant effects associated with the proposed project to the extent feasible, in accordance with State CEQA Guidelines ~~15002(a)(3), 15021(a)(2), and 15091(a)(1). The mitigation nuasures are numbered corresponding to the impacts that they address. For example, Mitigation Measure 4.2-1 would mitigate Impact 4.2-1. Level of Significance After Mitigation: This subsection describes whether mitigation measures would or would not reduce an impact to a less-than-significant level. This s~ction is presented in accordance with State CEQA Guidelines ~15126.2(b), which requires identification of significant unavoidable impacts. Significant unavoidable impacts are also summarized in Section 2.7 (Significant and Unavoidable Environmental Impacts).

These land use designations are defined by the General Plan as follows (City of Dublin, 1998): Public/Semi-Public Facility: This designation identifies areas where governmental or institutional type uses are anticipated, excluding parks owned by a public agency. These uses must also be of sufficient size to warrant differentiation from adjoining uses. Development of housing on a site designated on the General Plan as semi-public is considered consistent with the General Plan. Determination as to whether housing should be permitted on a specific semi- public site and the acceptable density and design will be through review of a Planned Unit Development proposal under the Zoning Ordinance. Floor Area Ratios (F ARs) are intended to be greater than 0.25 but not exceed 0.40. The appropriate employee density is 590 square feet per employee. Examples ofland uses designated as Public/Semi-Public Facility iii the General Plan include public and private schools, churches, the Civic Center, and BART parking at the proposed project site. Retail/Office: Shopping centers, restaurants, business and professional offices, motds, service stations, and sale of auto parts are included in this classification. Residential use is excluded except in the Downtown Intensification Area. FARs should be greater than 0.25 but not exceed 0.50.

The proposed West Dublin BART Specific Plan is one of three specific plan documents developeclfor the central urbanized area of the City of Dublin that address the future development in the downtown area of the City. Two other specific plan documents, the Downtown Core Specific Plan and the Village Parkway Specific Plan, have also been developed to address other sections in the downtown area. The Specific Plans are intended to direct the use of land, the design of public improvements, and the design and appearance of private and public development, including buildings, parking areas, signs and landscaping. Goals and objectives are included in the planning document to assist in fulfilling the intent of the Plan. Design Guidelines are also established in the context of the Plan to assist in guiding the design quality of the area's development. Son Francisco Boy Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village 4.1-5 EDAW Land Use The proposed West Dublin BART Specific Plan has not yet been adopted by the City of Dublin. The adoption of the proposed West Dublin BART Specific Plan by the Dublin City Council will require a General Plan Amendment to accommodate the proposed land use changes proposed within the Specific Plan Area. Additionally, the portions of the previously adopted (1987) Downtown Specific Plan located within the proposed West Dublin BART Specific Plan will require amendment to account for the new Specific Plan designation. Following Plan adoption, amendment of the City's Zoning Ordinance will be necessary for consistency with the General Plan (in order to ensure consistency between the new land use designations and parcel zoning). The proposed West Dublin BART Specific Plan area is generally located between 1-580 to the south and Dublin Boulevard to the north (Exhibit 4.1-3). San Ramon Road lies to the west of the area, and properties on the west side of Golden Gate Avenue are included in the plan area. The area consists of approximately 70 acres of commercial, office and light industrial land uses. The West DublinfPleasanton BART Station and Transit Village project is central to the Plan Area. The proposed West Dublin BART Specific Plan Area is intended to be a high-intensity mixed-use area, capitalizing on regional transit linkages provided by both the BART line and supported by nearby freeways (1-580 and 1-680). Within the proposed West Dublin BART Specific Plan Area, a mixture of low-rise and mid-rise buildings housing residences, offices, specialty retail, lodging, restaurant and similar uses are planned that are consistent with a transit-oriented area. In some instances, single land uses are located on a single site; however, thete are many mixed use developments. The proposed West Dublin BART Specific Plan Area also offers an opportunity to create a "window" into the City of Dublin. The proposed West Dublin BART Specific Plan Area, the Downtown Core Specific Plan Area (directly contiguous to the north) and the Village Parkway Specific Plan Area (to the east) represent what remains of the original "downtown" commercial area of the City of Dublin. The maximum amount of development in the proposed West Dublin BART Specific Plan Area is anticipated to be 1,750,055 square feet of non-residential space and 491 residential dwellings. THE CITY OF PLEASANTON GENERAL PLAN The City of Pleasant on General Plan, adopted August 6,1996, identifies goals, policies, and programs for land within its Planning Area. The General Plan Planning Area includes the City of Pleasanton's 27,200-acre Sphere of Influence (SOl), the 14,300-acre incorporated City limits, and areas within the jurisdiction of Alameda County that have been given land use designations on the Pleasanton General Plan Map.

The City of Pleasanton exercises zoning control and provides public services to areas included within the City limits. The proposed project is located within the City limits. The General Plan has 14 land use categories that establish consistent land uses. All projects proposed within the City's General Plan Planning Area must conform to the land use designation specified on the General Plan Map. The Pleasanton parcel's General Plan land use designation is Retail/ Highway/Service Commercial, Business and Professional Offices (Exhibit 4.1-2). This land use designation surrounds the Pleasanton parcel to the east, west, and south, while Public Health and Safety areas are found near the I-580 interchanges with I-680 and Foothill Road (Exhibit 4.1-2). These land use designations are defmed by the General Plan as follows (City of Pleasanton, 1996): Retail/Highway/Service Commercial, Business and Professional Offices: Floor Area Ratios (FARs) not to exceed 0.6, except for hotels or motels which should not exceed 0.7, and projects within the Central Business District (CBD), which should not exceed 2.0. Certain uses, such as warehouses, where employee density and traffic generation are minimal, may be allowed with higher FARs provided they are submitted as a Planned Unit Development (PUD) and meet all other City requirements. Public Health and Safety: Land set aside for the protection of the public health due to geologic, topographic, fire, or other hazards. No development is allowed in these areas other than one single-family unit on existing lots of record as of September 16, 1986, which meet City requirements for access, building site, and architectural design, ete. ZONING DESIGNATIONS CITY OF DUBLIN Zoning for the Dublin parcel is governed by the City of Dublin Zoning Ordinance, adopted in September 1997. The zoning designation for the majority of the Dublin parcel is M-l (Light Industrial) (Exhibit 4.1-4). East of Golden Gate Drive, the Dublin Parcel is zoned C-2 (Regional Commercial). The M-1 zoning district surrounds the Dublin parcel to the north and west, while the C-2 designation surrounds the site to the east (Exhibit 4.1-4). The C-1 (Commercial) zoning district can be found further west of the site.

The zoning designation for the Pleasanton parcel is governed by Ordinance No. 1014 (January 1982), which approved the rezoning of a 91.5-acre site from High Density Residential (HDR) and Open Space (OS) to Planned Unit Development-Commercial and Offices (PUD-C-O). This site, which is bounded by Stoneridge Drive, Stoneridge Mall Road, 1-580 and 1-680, includes the entire Pleasanton parcel as well as the land directly southeast of the site (Exhibit 4.1-4). Two commercial zoning designations border the Pleasanton parcel to the west, C-R (m) (Commercial- Regional (enclosed mall)) and C-R (p) (Commercial-Regional (peripheral area)). The PUD-GO, C-R (m), and GR (p) zoning designations are defmed by the City Zoning Ordinance and Ordinance No. 1014 as follows: PUD-C-O (Planned Unit Development-Commercial-Office): Ordinance No. 1014 specifies the applicable zoning guidelines for the 91.5 acre site that incorporates the entire Pleasanton parcel. The Daon Corporation applied for the rezoning of this site for the development of an office/commercial/residential complex. Although the Daon Corporation no longer owns the area referred to in this EIR as "the pleasanton parcel," the zoning guidelines set forth by Ordinance No. 1014 for the PUD-GO zoning district are still applicable to the entire 91.5 acre site, including the Pleasanton parcel of the project site. Ordinance No. 1014 states that "all buildings (proposed on the subject property) and all individual site landscaping and parking shall require approval by the Design Review Board prior to issuance of building permits." In addition, no buildings shall be over five stories in height. Use types permitted within this zoning district, subject to approval by the Design Review Board, include commercial buildings, office complexes, and residential developments. C-R (m) (Commercial-Regional (enclosed mall)): The purpose of this designation is to provide a large site at an appropriate location for a major shopping center drawing trade from the entire Amador-Livermore Valley as well as to ensure that a major center will be developed in accordance with high standards of site planning, architecture, and landscape design. The (m) designation is intended for uses that are part of a completely enclosed mall complex, for which all activities take place entirely indoors. Permitted uses include: Appliance sales and repair; art galleries; automobile rental, sales, and supply stores (not service shops); beauty shops; bowling alleys; department stores; and photographic studios and supply stores. C-R (p) (Commercial-Regional (peripheral area)): The purpose of this designation is to also provide a large site at an appropriate location for a major shopping center drawing trade San Francisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 4.1-11 EDAW land Use from the entire Amador-Livermore Valley as well as to ensure that a major center will be developed in accordance with high standards of site planning, architecture, and landscape design.

PROJECT IMPACTS ComTJatibilitv with SurroundinR Land Uses - Dublin Parcel. The proposed project would include a residential complex, a hotel, and associated parking facilities on the Dublin parcel in an area surrounded by commercial and office uses as well as the Cor-Q-Van warehouse building. These surrounding uses only operate during the day and, thus, would not be expected to generate noise or traffic during the nighttime hours that could disrupt residents and hotel guests (Noise is evaluated separately in Section 4.3). There is no direct access to the warehouse building through the site. In addition, the proposed design for the residential complex is focused toward Golden Gate Drive with parking located to the rear in order to provide a pedestrian orientation within a commercially- developed area. Therefore, the proposed project would have a less-than- significant land use compatibility impact related to development on the Dublin parcel. Impact 4.1-1 The Dublin parcel is currently surrounded by a Cor-O- V an warehouse building to the west, a parking area used for Cor-O- Van trailers to the north, and commercial and office buildings located further north and to the east (See Exhibit 4.1-1). The proposed BART parking structure would be located on the easternmost portion of the site, near existing parking areas for commercial and office-related uses. Both the residential complex and the hotel would be developed in close proximity to the Cor-O- Van warehouse building; however, no significant land use compatibility issues would be expected. No access road to this building exists within the project site, so trailers transporting merchandise to and San Francisco Bay Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village 4.1-13 EDAW Land Use from the Cor-O-Van warehouse would not create a substantial noise or traffic-related disturbance for residents. In addition, the proposed design of the residential complex is focused toward Golden Gate Drive with parking located to the rear in order to provide more of a pedestrian orientation within the surrounding commercial area. Also, the central courtyard design of the building would provide a more residential setting for the occupants than what currently exists in the local area and would shift their focus away from the adjacent warehouse building and truck parking lot. The siting of the hotel development near 1-580 would encourage hotel guests to utilize BART's system of public transportation. Although hotel guests might be affected by traffic noise on 1-580, this potential impact would be considered noise-related and is discussed in further detail in Section 4.3. The commercial and office buildings located to the north and east of the project site only operate during the day, so operational noise and traffic generated by these uses would not be expected during the nighttime hours when people are more sensitive to noise. In addition, there are no adjacent industrial uses or sources of hazardous materials that would directly affect the compatibility of the proposed residential uses within the surrounding area. The proposed project, therefore, would have a less-than- significant land use compatibility impact related to development on the Dublin parcel. Compatibility with Surroundinf! Land Uses - Pleasanton Parcel. Land uses surrounding the parcel include office buildings to the west and east and the Stoneridge Mall and associated parking facilities to the south. Development of the proposed project would be consistent with these surrounding land uses. Therefore, no impacts related to compatibility with surrounding land uses would be anticipated. Impact 4.1-2 The Pleasanton parcel is surrounded by office buildings to the west and east and the Stoneridge Mall and associated parking facilities to the south (See Exhibit 4.1-1). The development of a 5-story office building on the Pleasanton parcel would be consistent with the office type uses that currently surround the project site. The proposed parking facilities for the Pleasanton parcel (i.e., the BART parking structure and the parking lots for the office building) would be located near existing parking facilities. Therefore, the proposed land uses for the Pleasanton parcel would be consistent with existing land uses surrounding the project site. In addition, developing a BART Station within walking distance from the Stoneridge Mall would encourage patrons and employees of the mall and offices to utilize public transportation, which in effect, would reduce traffic congestion within the area. No impacts related to land use compatibility would be anticipated with project implementation.

The proposed hotel and residential uses would be inconsistent with the current Public/Semi-Public land use designation and the Light Industrial and Regional Commercial zoning designations for the site. These inconsistencies with existing land use plans would be removed if the proposed West Dublin BART Specific Plan and related changes to the City of Dublin General Plan, Downtown Core Specific Plan, and zoning designation of the project site are adopted as proposed. If the proposed West Dublin BART Specific Plan is not adopted, the Dublin General Plan, Downtown Core Specific PTan and zoning designation for the site must be amended to accommodate the residential and hotel uses. In either case, the residential and hotel uses shall not be constructed on the Dublin parcel until these changes to existing land use requirements have been adopted. Accordingly, this impact would be less than significant. The Dublin parcel is currently designated Public/Semi-Public Facility by the Dublin General Plan. This land use designation was assigned to the Dublin parcel with the intent of developing future BART parking facilities at this location. A parking structure for BART patrons is, indeed, proposed on the l)ublirlParcel as ""ell.as (l160~1.11ritf(~sid~ntial~omplex and a 240-room hotel. According to the Dublin General Plan, the Public/Semi-Public Facility designation is intended for uses owned by a public agency, other than parks, that are of sufficient size to warrant differentiation from adjoining uses. Although the parking facilities would be consistent, the residential and hotel land uses would not be considered compatible with the Public/Semi-Public designation. This inconsistency would be removed if the proposed West Dublin BART Specific Plan and related changes to the City of Dublin General Plan, Downtown Core Specific Plan, and wning designation of the project site are adopted as proposed.

CLIMATE The climate of the Livermore- Amador Valley is characterized as Mediterranean, with cool wet winters and warm dry summers. The average annual temperature of the area ranges from a low of 42 degrees (Fahrenheit) to a high of 73 degrees. The mean annual rainfall in the vicinity of the project site, the majority of which falls between October and April, is approximately 17 inches. Analysis of long-term precipitation records indicates that wetter and drier cycles lasting several years are common in the region. Severe, damaging rainstorms occur at a frequency of about once every 3 years. SURFACE WATER The project site is located on the western margin of the Livermore-Amador Valley hydrologic region. The site is relatively flat, with the predominant topographic features consisting of several 5- to 10-foot- high soil mounds located on both parcels. Ground surface elevations range from a low of approximately 340 feet above mean sea level along the eastern edge of the site to approximately 350 feet above mean sea level along the western edge of the project site. Because of the flat character of both parcels, precipitation generally infiltrates into the site's soils during storm events. On the Dublin parcel, the stormwater that does drain off the site generally flows to the east into existing storm drains within Golden Gate Drive and to the south into Dublin Creek. Dublin Creek is. an open channel that forms the southern boundary of the Dublin parcel. Dublin Creek drains an area of approximately 3.7 square miles, with a design peak flow of 1649 cubic feet per second (Woodward-Clyde Consultants, 1989). Dublin Creek is the on1y sUrface water feature located adjacent to the project site. On the Pleasanton parcel, any stormwater discharge flows east either into existing storm drains within the adjacent parking lots or into a small drainage culvert paralleling the southbound ramp connecting Interstate 580 and Interstate 680. This stormwater evenmally flows into the local creek system. Dublin Creek conveys runoff from the Donlan and Devaney hills to the west, and flows east through the project area until its confluence with Alamo Creek east of the 1-580/1-680 Interchange. From this r t San Froncisco Boy Area Rapid T ronsit District West Dublin/Pleasanton BART Station and T ronsit Village 4.2-1 EDAW Hydrology and Water Quality confluence, Alamo Canal, as it is referred to in this area, flows south into Arroyo de la Laguna and Alameda Creek. Water flowing in these creeks eventually discharges into San Francisco Bay through the Coyote Hills Alameda County Flood Control Channel. Hydrologic features of the area, including the creeks and nearby flood-prone locations (discussed below), are identified in Exhibit 4.2-1. In an undeveloped setting, when rainfall intensities exceed the infiltration capacity of surface soils, run- off flows over the ground surfaces toward established natural drainage channels. Stormwater runoff is then conveyed away from the area in creeks and streams. In a developed setting, an increased portion of the natural soils would be covered with impervious surfaces (i.e., roads, driveways, and roofs), increasing amounts and altering flow patterns of runoff. In developed portions of Dublin and Pleasanton, storm drainage is conveyed in underground pipes, channels, and, to a lesser extent, swales. New development is required to install adequately-sized storm drains, connected to the cities' systems, to accommodate increased runoff volumes. FLOODING The project site is not located within a 100-year flood hazard area, as delineated on the IOO-year flood zone maps included in the general plans for the cities of Dublin and Pleasanton. According to these maps, peak stormwater flows would remain within the defmed channel of Dublin Creek within the project area. Slightly northeast of the project site, the 500-year floodplain extends beyond the flood control channel. This area does not include the project site and should not affect the proposed development on the Dublin parcel (Exhibit 4.2-1). Within the vicinity of the proposed project, the IOO-year and 500-year flood hazard zones extend east of 1-680 past Hopyard Road (Exhibit 4.2-1). These flood hazard areas are located downstream of Dublin Creek and are predominately associated with the Alamo and Chabot canals located east of 1- 680. GROUNDWATER The project site is located within the Livermore Valley groundwater basin, which covers an area of approximately 582 square miles. It extends from San Ramon on the north to just north of the southern EDAW Hydrology and Water Quality San Francisco Bay Area Rapid Transit District 4.2-2 West Dublin!Pleasanton BART Station and Transit Village Jt C; . ..

Alameda County border and is bound by the Diablo Mountain Range on the west. The Livermore Valley basin is comprised of several coalescing alluvial valleys developed along the major streams that flow into the basin. The alluvial sediments, including the recent alluvium and underlying Livermore Gravels that have filled the valleys, contain important aquifers that provide domestic, municipal, industrial, and agricultural water supply. These aquifers form the Livermore groundwater basin. The basin is subdivided into twelve sub-basins on the basis of topography and geology. The project site is located within the Dublin Sub-basin, which covers approximately 7.8 square miles in the northwest portion of the Livermore Valley basin. The Dublin Sub-basin consists of both ~c()~.rlih~d aquife~s in recent alluvial deposits as well as deeper confmed or semi -confmed aquifers within coarse alluvium, separated by fmer-grained deposits. t r The groundwater resources in the Livermore groundwater basin are managed by the Alameda County Flood Control and Water Conservation District, Zone 7 (Zone 7). As part of a groundwater management plan, Zone 7 maintains a groundwater monitoring network of 210 wells to provide regional data on basin-wide groundwater conditions. Contour maps of the groundwater elevations (water levels) within the basin are compiled in the fall and spring of each year. In the area of the proposed project, groundwater levels are relatively shallow, ranging from 8 to 19 feet below the surface (Woodward-Clyde Consultants, 1989). Data collected for the Livermore groundwater basin indicates that groundwater flows south through the Dublin sub-basin from the northern Bishop Sub-basin with a gradient of 20 feet per mile (Woodward-Clyde Consulting, 1989). The direction of groundwater flow is consistent with the topographic and geologic conditions in the local area. WATER QUALITY The quality of surface and groundwater at the project site is affected by land uses within the entire watershed. Drainage from the site affects the quality of water in larger creeks and drainages downstream, including Arroyo de la Laguna, Alameda Creek, and San Francisco Bay. r . ! Water quality in surface and groundwater bodies is regulated primarily by the State and regional water quality control boards. The surface and groundwater quality in the project area is under the jurisdiction of the San Francisco Bay Regional Water Quality Control Board (RWQCB), which is responsible for implementation of State and federal water quality protection guidelines in the vicinity of the project site. The RWQCB has adopted the San Francisco Bay Basin Water Quality Control Plan (Basin Plan) to implement plans, policies, and provisions for water quality management. The most recent revision of the Basin Plan was adopted by the RWQCB in June 1995 and was approved by the State Water Resources Control Board (SWRCB)in November 1995. The BaSin Plan identilles existing and potential beneficial uses supported by the key surface water drainages throughout the Bay Area as well .r ~..

III as water quality objectives for toxic pollutants and bacteriological parameters that are intended to .. protect the beneficial uses of the Bay. SURFACE WATER Water quality monitoring data for Dublin Creek, which is adjacent to the Dublin parcel, was provided in the Water Resources Technical Report prepared for the DPX Project (Woodward-Clyde Consultants, 1989). According to this report, calcium and sodium are the predominant ions within the Dublin Creek watershed. The values of water quality constituents such as total dissolved solids and nitrate found within Dublin Creek were below the water quality objectives set forth by the Basin Plan. Water quality within local drainages directly affects the aquatic resources within San Francisco Bay. The Bay's water quality is affected by freshwater inflows, tidal mixing, urban runoff, municipal and industrial discharges, and atmospheric deposition. The water quality parameters of greatest interest for the Bay include salinity, temperature, pH, nutrients, dissolved oxygen, coliform bacteria, trace contaminants, and suspended sediments. Approximately 40 percent of the total oxygen demand and about 20 percent of the nutrient loads to San Francisco Bay are released from Alameda County (Woodward-Clyde Consultants 1989). GROUNDWATER Regional groundwater quality within the Livermore Valley has been monitored by the U.S. Geological Service (USGS) and Zone 7. Groundwater quality in the Dublin Sub-basin north ofI -580 is thought to be excellent in quality and suitable for municipal or other uses (Woodward-Clyde Consultants, 1989). The majority of groundwater is bicarbonate in nature, containing calcium as the predominant ion west of South San Ramon Creek, and sodium as the predominant ion east of South San Ramon Creek. Poor quality groundwater occurs south ofI-580 due to high concentrations of chloride, sulfate, and boron. In addition, the concentration of total dissolved solids found in groundwater south of 1- 580 ranges from 350 to 2000 mg/l, which is considered high when compared to the 500 mg/l Basin Plan objective fot this water quality constituent (Woodward-Clyde Consultants, 1989). Potential sources of surface or subsurface water quality degradation exist within the project area. Multiple contamination sites that have the potential to affect the soils or shallow groundwater in the local area are located within the vicinity of the proposed project (See Public Health and Safety, Section 4.7, for further discussion). In addition, urban stormwater pollutants (e.g., petroleum fuels, lubricants, and metals) and home maintenance pollutants (e.g., pesticides, fertilizers, and cleaning materials) can result in water quality degradation.

PROJECT IMPACTS r I ' Impact 4.2-1 r- i t r-" f Stormwater DischarJ!e. Development of the proposed project would result in the construction of impervious surfaces within the project site and may increase runoff. The DPX EIR concluded that the hydrologic impacts associated with development of the project site would be less than significant because of the relatively small total area of the site when compared to the overall drainage area served by local flood control channels. Because the proposed project would develop the same area on the site as assumed in the DPX EIR, no new significant stonnwater drainage impacts would be expected. This would be considered a less-than-significant impact. The proposed project would create new impervious surfaces on the project site, altering the site's existing d.ra.inage patterns and increasing site runoff. Undeveloped, vegetated lands generally have low runoff coefficients, meaning that they yield a relatively small portion of the total rainfall as runoff. The majority of the precipitation, particularly in smaller storms, infIltrates into the subsurface. On the other h~~d.,illlpervi~us ~l1rfa~es 0~ldIle~ly au raWillas runoff. The DPX EIR identified the hydrologic impacts associated with development of the project site as less than significant because of the relatively small total area of the site when compared. to"the overall drainage area served by local flood control channels (DPX EIR, p. 4-109). The DPX EIR assumed that 100% of the project site would be impervious following construction of the proposed BART parking lots. The proposed project would have a similar impervious area. Because the proposed project would include the same total impervious area as anticipated in the DPX EIR, no new significant stormwater drainage impacts would be anticipated. Impact 4.2-2 r- Effects on Water Qualitv. Construction activities and operational site uses associated with the project could result in degradation of water quality in nearby surface water bodies and groundwater reservoirs by reducing the quality of stormwater runoff. This would be considered a significant impact. Construction and grading within the project site would require temporary disturbance of surface soils and removal of vegetative cover. During the construction period of the project, grading and excavation 4.2-9 EDAW Hydrology and Water Quality r. L Son Francisco Boy Area Rapid Transit District West Dublin!Pleasanton BART Station and Transit Village activities would result in exposure of soil to runoff, potentially causing erosion and entrapment of sediment in the runoff Soil stockpiles and excavated portions of the project site would be exposed to runoff and, if not managed properly, the runoff could cause erosion and increased sedimentation in storm sewers or water courses at or away from the project site. The accumulation of sediment could result in blockage of flows, potentially resulting in increased localized ponding or flooding. Chemicals could be released at construction sites during grading operations. Once released, substances such as fuels, oils, paints, and solvents could be transported to Dublin Creek and/or groundwater in stormwater runoff, wash water, and dust control water, potentially reducing the quality of the receiving waters. In addition, increased rates of uncontrolled runoff could result in erosion of site soils. Such erosion could cause increased turbidity or sedimentation in Dublin Creek as well as in waterways located downstream of the project site, including Alamo Canal, Arroyo de la Laguna, and Alameda Creek, which could adversely affect aquatic habitat. Although the DPX EIR concluded that the effects on water quality resulting from implementation of the DPX Project, including development on the project site, would be less than significant, the proposed project has the potential to significantly affect water quality on a regional leveL Concern for water quality in San Francisco Bay has shifted since the 1960s and 1970s from a focus on organic and bacterial contamination to a concern for the potential toxic impact of trace contaminants, including trace elements and trace organics (ESA, 1998). One of the primary sources of trace contaminants to the Bay include river inflow and urban and non-urban runoff from upstream sources. Although the project site is small in comparison to the entire drainage area feeding into the Bay, the proposed project could incrementally contribute to the amount of trace contaminants entering the Bay via urban runoff. In addition, additional sources of surface and/or subsurface water quality degradation that were not of concern for the DPX EIR, such as recent contamination sites or increased urban runoff due to development in the cities of Dublin and Pleasanton, may currently exist within the project area. Therefore, the proposed project's effects on water quality would be considered significant. Flooding. The project site is not located within a 1 DO-year or SOD-year flood hazard area, as delineated in the general plans for Dublin and Pleasanton. However, within the vicinity of the proposed project, the 1 DO-year and SOD-year flood hazard zones extend east of 1-680 past Hopyard Road. These flood hazard areas are located downstream of Dublin Creek and runoff from construction or operational activities on the project site could contribute to downstream flooding. However, this contribution would not be substantial given the relatively small total area of the site when compared to the overall drainage area of the region. This would be considered a less-than-significant impact.

An SWPPP should include Best Management Practices (BMPs) designed to reduce potential impacts to surface water quality through the construction and life of the project. An SWPPP shall be prepared such that, when properly implemented, it will reduce or eliminate impacts to surface water quality from all phases of the project. Required elements of the SWPPP include: Construction Stormwater Management Controls. These controls shall include practices to minimize the contact of construction materials, equipment, and maintenance supplies (e.g., fuels, lubricants, paints, solvents, adhesives) with stormwater. The SWPPP shall specify properly designed centralized storage areas that keep these materials out of the rain. An important component of the stormwater quality protection effort is knowledge of the site supervisors and workers. To educate on-site personnel and maintain awareness of the importance of stormwater quality protection, site supervisors shall conduct regular tailgate meetings to discuss pollution prevention. The frequency of the meetings and required personnel attendance shall be specified in the SWPPP. The SWPPP shall specify a monitoring program to be implemented by the construction site supervisor, and must include both dry and wet weather inspections.

It is characterized by two parameters: amplitude (loudness) and frequency (tone). AMPLITUDE '- Amplimde is the difference between ambient air pressure and the peak pressure of the sound wave. Amplitude is measured ill deCibels (dB) on alog3.flthrrllCscale. For example, a 10'dB sound is 10 times the pressure difference of a 0 dB sound; a 20 dB sound is 100 times the pressure difference of a 0 dB sound. Another feature of the decibel scale is the wa.y ill which sound amplitudes from multiple sources add together. A 65 dB source of sound, such as a truck, when joined by another 65 dB source results in a sound amplitude of 68 dB, not 130 dB (i.e., doubling the source strength increases the sound pressure by 3 dB). Amplitude is interpreted by the ear as corresponding to different degrees of loudness. Laboratory measurements correlate a '10 dB increase in amplitude with a perceived doubling of loudness and establish a 3 dB change in amplimde as the minimum audible difference perceptible to the average person (Federal Highway Administration 1982). - f t : t.. FREQUENCY Frequency is the number of fluctuations of the pressure wave per second. The unit of frequency is the Hertz (Hz). One Hz equals one cycle per second. The human ear is not equally sensitive to sound of different frequencies. Sound waves below 16 Hz or above 20,000 Hz cannot be heard at all, and the ear is more sensitive to sound in the higher portion of this range than in the lower. To approximate this sensitivity, environmental sound is usually measured in A-weighted decibels (dBA). On this scale, the normal range of human hearing extends from about 10 dBA to about 140 dBA.

West Dublin/Pleasanton BART Station and Transit Village Project IN OT012.01 7/00 IIiDI iii f: ) 9 a--- Noise Descriptors The intensity of environmental noise fluctuates over time, and several descriptors of time-averaged noise levels are used.. Three most commonly used are Leq, Ldn' and CNEL. The energy equivalent noise1evel, Leq, is a measure of the average energy content (intensity) of noise over any given period of time. Many communities use 24-hour descriptors of noise levels to regulate noise. The day-night average noise level, Ldn, is the 24-hour average of the noise intensity, with a 10 dBA "penalty" added for nighttime nOIse (10:00 PM to 7:00 AM) to account for the greater sensitivity to noise during this period (California Code of Regulations 1988). CNEL, the community equivalent noise level, is similar to Ldn, but adds an ad<iitional5 dBA penalty to evening noise (7:00 PM to 10:00 PM). Characteristics of Sound Propagation and Attenuation Noise can be generated by a number of sources, including mobile sources, such as automobiles, trucks and airplanes, and stationary sources, such as construction sites, machinery, aIld ind.ustrialoperations. Noise generated by mobile sources typically attenuates at a rate between 3.0 to 4.5 dBA per doubling of distance. c!~~J::l.te depends on the ground surface and the number or type of objects between the noise source and the receiver. Hard and flat surfaces, such as concrete or asphalt, have an attenuation ~~teor~.;RAAA per doubling of distance. Soft surfaces, such as uneven or vegetated terrain, have an atten\lation rate of about 4.5 dBA per doubling of distance. Noise generated by stationary sources typically attenuate at a rate between 6.0 to about 7.5 dBA per doubling of distance. Sound levels can be reduced by placing barriers between the noise source and the receiver. In general, barriers contribute to decreasing noise levels only when the structure breaks the "line of sight" between the source and the receiver. Buildings, concrete walls, and berms can all act as effective noise barriers. Wooden fences or broad areas of dense foliage can also reduce noise, but are less effective than solid barriers. r I , Human Response to Noise ~ The human response to environmental noise is subjective and varies considerably from individual to individual. Noise in the community has often been cited as a health problem, not in terms of actual physiological damage, such as hearing impairment, but in terms of inhibiting general well-being and contributing to undue stress and annoyance. The health effects of noise in the community arise from interference with human . activities, including sleep, speech, recreation, and tasks demanding concentration or coordination. Hearing loss can occur at the highest noise intensity levels. When community noise interferes with human activities or contributes to stress, public annoyance with the San Francisco Bay Area Rapid T ronsit District West Dublin/Pleasanton BART Station and T ronsit Village 4.3-3 EDAW Noise r t /93 iii noise source increases. The acceptability of noise and the threat to public well-being are the basis for . land use planning policies preventing exposure to excessive community noise levels. Because construction activities are typically short-term, the associated effects of construction-generated noise are typically limited to annoyance and interference with speech. Within an exterior noise environment, noise levels in excess of 60 dBA are generally considered to have an appreciable effect on speech interference. The level at which speech interference occurs is based on an average sentence comprehension rate of approximately 98 percent at five meters. Greater speaker-listener distances would be possible indoors at the same level of vocal effort and speech intelligibility, because sound pressure levels diminish more slowly than predicted by the inverse square law, which is typically used in the exterior environment (EPA 1971). Unfortunately, there is no completely satisfactory way to measure the subjective effects of noise, or of the corresponding reactions of annoyance and dissatisfaction. This is primarily because of the wide variation in individual thresholds of annoyance, and habituation to noise over differing individual experiences with noise. Thus, an important way of determining a person's subjective reaction to a new noise is the comparison of it to the existing environment to which one has adapted: the so-called "ambient" environment. In general, the more a new noise exceeds the previously existing ambient noise level, the less acceptable the new noise will be judged by the hearers. With regard to increases in A- . weighted noise level, knowledge of the following relationships will be helpful in understanding this report (EP A 1971): . Except in carefully controlled laboratory experiments, a change of 1 dB cannot be perceived by humans. · Outside of the laboratory, a 3 dB change is considered a just-perceivable difference. . A change in level of at least 5 dB is required before any noticeable change in community response would be expected. . A 10 dB change is subjectively heard as approximately a doubling in loudness, and would almost certainly cause an adverse change in community response. NOISE REGULATIONS AND GUIDELINES A number of government agencies have established noise standards and guidelines to protect citizens from potential hearing damage and various other adverse physiological and social effects associated with nOIse.

Source: City of Dublin General Plan, July 7,1998 """., , i CITY OF PLEASANTON The City of Pleasant on General Plan Noise Element provides standards and programs to avoid noise- related impacts from existing uses and new developments. The General Plan aims to "reduce noise to acceptable levels throughout the community" (Goal 1, Noise Element) by (1) requiring new development to meet acceptable exterior noise level'standards (Policy 1, Noise Element), (2) by ensuring that interior noise levels do not exceed 45 dBA Ldn for residential uses (Policy 3, Noise r Son Francisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 4.3-5 EDAW . Noise j CJ5" Element); and (3) by controlling noise at its source to maintain existing noise levels (Policy 4, Noise Element). The standard of 60 dBA Ldn for exterior noise levels is to be attained through on-site noise mitigation measures for new residential projects (Program 1.2), through installing feasible mitigation measures in existing areas of excessive noise (Program 2.1), and by designing street patterns to not exceed 6,000 to 9,000 vehicles/day on residential local and collector streets (Program 7.2) as the City grows. The City of Pleasanton Land Use Compatibility For Community Noise Environments chart is presented in Table 4.3-2. As indicated, the acceptable exterior noise exposure level for the City of Pleasanton is 60 Ldn for residential, school, hotel, and motel land uses and 65 Ldn for outdoor recreation areas. The General Plan noise standards have been established so that the noise level in the active open space areas of residential neighborhoods (the rear yards in detached single-family homes and recreation areas in multi-family housing developments) is at or below 60 dBA Ldl1 and the interior living area is at or below 45 dBA Ldn' In addition, community concern was expressed during the 1996 General Plan update over the negative visual impact associated with the use of soundwalls to mitigate vehicular traffic noise. As a result, the existing City programs which call for the installation of noise mitigation measures, primarily soundwalls, were modified to encourage the use of greater building setbacks, earth berms, and other non-soundwall design solutions. While these techniques can work for new developments, quite often soundwalls are the only available option for existing structures due to physical space constraints.

These standards require that acoustical studies be performed prior to construction at building locations where the existing Ldn exceeds 60 dBA. Such acoustical studies are required to establish mitigation measures that will limit maximum Ldn levels to 45 dBA in any inhabitable room. Although there are no generally applicable interior noise standards pertinent to all uses, many communities in California have adopted an Ldn of 45 as an upper limit on interior noise in aU residential units. EXISTING NOISE ENVIRONMENT The major noise source affecting both the Dublin and Pleasanton parcels is vehicular traffic on Interstate 580 (1-580). Additional noise sources within the area include intermittent noise associated with BART train passbys, aircraft flyovers from nearby airports, and vehicle traffic on area roadways. Based on the traffic noise modeling conducted for this project, ambient noise levels at both parcels are estimated to range from approximately 70 to 80 dBA, depending on distance from 1-580. No noise- sensitive land uses are located in the vicinity of the project site. A 24-hour ambient noise survey was conducted on May 23rd and 24th, 2000, on the Dublin parcel to document the existing noise environment in the vicinity of the proposed residential development. The noise measurement location was approximately 100 feet north of the Dublin parcel's southern property line. The result of the noise measurements are shown in Table 4.3-4. The table displays the CNEL A- weighted sound level measured during the survey as well as the minimum (Lmin), maximum (Lmax), and equivalent (average) hourly (Leq) sound level measured. As indicated, noise levels at the project site averaged approximately 75 dBA over a 24-hour period at a distance of approximately 100 feet north of the southern property line. The average hourly noise level was approximately 69 dBA. Noise levels recorded during the nighttime hours reached a low of approximately 39 dBA and daytime peak traffic hour noise levels reached a high of nearly 85 dBA. EXISTING TRAFFIC NOISE LEVELS Existing traffic noise levels were calculated for roadway segments in the project areas using the Federal Highway Administration's Highway Noise Prediction Model based on the average daily traffic volumes on major roadways within the project area. Table 4.3-5 presents the calculated distance from the roadway centerline to the existing CNEL/Ldn levels (in dBA) at various roadway segments, as well as the calculated noise level at 50 feet from the centerline of the near travel lane.

Calculated traffic noise levels along local roadways in the vicinity ofthe Dublin parcel, range from approximately 59 dBA CNEL along Golden Gate Drive to approximately 69 dBA CNEL along Dublin Boulevard. In the vicinity of the Pleasanton parcel, calculated traffic noise levels range from approximately 61 dBA CNEL along Stoneridge Drive to approximately 69 dBA CNEL along Foothill Road. NOISE-SENSITIVE LAND USES Noise-sensitive land uses are generally considered to include those uses which would result in noise exposure that could result in health-related risks to individuals, as well as places where quiet is an essential element of their intended purpose. Residential dwellings are of primary concern because of the potential for increased and prolonged exposure of individuals to both interior and exterior noise levels. Additional land uses such as parks, historic sites, cemeteries, and recreation areas are also considered sensitive to increases in exterior noise levels. Schools, churches, hotels, libraries, and other places where low interior noise levels are essential are also considered noise-sensitive land uses. Noise- sensitive land uses are presented in Table 4.3-6.

As discussed in Section 4.1 - Land Use, of this EIR, land uses located acljacent to tb.eDublitl and Pleasanton parcels are primarily commercial and light-industrial.

The Crowne Plaza Hotel is located approximately 2,300 feet west of the site, at the northwest corner of Foothill Road and Dublin Canyon Road. r- t 4.3.2 ENVIRONMENTAL IMPACTS THRESHOLDS OF SIGNIFICANCE For the purposes of this analysis, significant noise impacts are measured as follows: r Short-term Construction Noise Impacts. Short-term construction noise impacts associated with the transit village uses would. be considered significant if construction activities worild reslllt in a noticeable increase in average daily ambient noise levels of 3 dBA, or greater, at nearby noise-sensitive land uses. For the BART facilities, construction noise impacts would be considered significant if they exceed the 70 dBA thresholds identified in Table 4.3-3 for semi-residential/commercial areas. umg- Term Operational Noise Impacts. Long-term operational noise impacts, including stationary source and. traffic noise impacts, ,would be considered significant if the proposed project would result in an increase in ambieI1tnoise levels that exceeds 60 dBA (CNEL) at existing noise-sensitive land uses and the increase was noticeable to the average person (defmed as 3 dBA CNEL or greater). Land Use Compatibility With Projected Noise Levels. Development of the proposed land uses would have a significant impact if projected on-site noise levels were to exceed the "normally acceptable" noise criterIa established by each respective jUrisdiction. Land use compatibility noise criteria established. by the cities of Dublin and Pleasanton, are presented in Tables 4.3-1 and 4.3-2, respectively. SHORT-TERM NOISE IMPACTS Impact 4.3-1 Noise from Construction Activities in the Project Area. Construction activities within the project area would generate intermittent and temporary increases in ambient noise levels that would exceed significance thresholds. This impact is considered significant. Son Francisco Boy Area Rapid Transit District ,. West Dublin!Pleasanton BART Station and Transit Village 4.3-11 EDAW Noise :20/ Construction noise typically occurs intermittently and varies depending upon the nature or phase (e.g., demolition/land clearing, grading ,and excavation, erection) of construction. Noise generated by construction equipment, including earth movers, material handlers, and portable generators, can reach high levels. Although noise ranges were found to be similar for all construction phases, the grading phase tended to involve the most equipment. The U.S. Environmental Protection Agency (EP A) has found that the noisiest equipment types operating at construction sites typically range from 88 dBA to 91 dBA at 50 feet. Typical operating cycles may involve 2 minutes of full power, followed by 3 or 4 minutes at lower settings (EPA 1971). Table 4.3-71ists noise levels generated by typical construction equipment at a distance of 50 feet. Noise from localized point sources (such as construction sites) typically decreases by about 6 dBA with each doubling of distance from source to receptor. Given this noise attenuation rate and assuming no noise shielding from existing natural or man-made features (trees, buildings, fences, etc.), outdoor receptors within approximately 1,600 feet of construction sites could experience maximum instantaneous noise levels of greater than 60 dBA when onsite construction-related noise levels exceed approximately 90 dBA at the project site boundary.

IIlIl ooa- :........ f I , t As previously discussed, the nearest existing noise-sensitive receptors are located at distances of 1,000 feet and 500 feet from the Dublin and Pleasanton parcels, respectively. Depending on the time of day during which conStruction activities occur, these nearby noise-sensitive receptors could experience increases in average daily ambient noise levels of greater than 3 dBA. In addition, should onsite construction activities continue to occur after completion and occupancy of the proposed onsite noise- sensitive receptors on the Dublin parcel (i.e., residential dwellings and hotel), projected intenl1ittent noise levels at the proposed onsite noise-sensitive land uses would likely exceed 80 dBA and would result in an increase of greater than 3 dBA in ambient noise levels. Because noise-generating construction activities would result in a short-term increase in ambient noise levels of greater than 3 .dBA at nearby noise-sensitive land uses and because construction noise levels could exceed 80 dBA at the noise-sensitive hotel and residential units on the Dublin Parcel if construction continues following the,ir occupation (BARTs construction noise threshold in semi-residential/commercial areas is 70 dBA), this impact is considered significant. LONG-TERM NOISE IMPACTS ~ ~ t Impact 4.3-2 Increases in Area and Stationary Source Noise. On-site area and stationazy sources of noise associated with the proposed land uses would result in only minor and intermittent increases in ambient noise levels, which would occur primarily during the day and evening hours and less frequently at night. Noticeable increases in ambient noise levels (i.e., 3 dBA, or greater) at nearby noise-seTlsitiv.~ receptors are not anticipated. Therefore, this impact would be considered less than significant. Noise levels typically associated with the proposed project's land uses and related noise impacts are discussed below. Residential Land Uses ~ ~ Noise typically associated with residenti~dweilingsinci~de human voices, amplified music, and noise generated by lawn maintenance equipment. However, these area source noises are typically intermittent and occur predominantly during the daytime hours. As a result, noise from area sources are not anticipated to result in a substantial increase in ambient noise levels. Noise levels generated by stationary sources are typically associated with the use of heating, ventilation, and air conditioning units. Maximum noise levels from residential heating and air conditioning units typically average less than 50 dBA at 10 feet from the source (EPA 1971). As previously discussed, the nearest existing noise-sensitive land use in the vicinity of the Dublin parcel is the Best Western Monarch Hotel, located ,..... ~ r t 1 San Francisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 4.3-13 EDAW Noise dD3 approximately 1,000 feet west of the project site. Operational noise levels would not exceed the 60 dBA noise threshold given the distance to existing noise-sensitive receptors, projected operational noise levels associated with the proposed residential development would not result in an increase in exterior ambient noise levels at nearby noise-sensitive receptors. OFFICE AND HOTEL LAND USES Daily maintenance and operational activities associated with the proposed office and hotel uses could result in minor increases in ambient noise levels, primarily associated with the operation of mechanical building equipment. As with the proposed residential development, minor intermittent noise would occasionally be generated by human voices and the operation of landscaping equipment, as well as on- site delivery and maintenance vehicles. Area sources of noise associated with the proposed development would result in only minor and intermittent increases in ambient noise levels primarily during the day and evening hours and less frequently at night. Noise-generating mechanical equipment associated with commercial and office land uses typically include air and water circulation systems (e.g., heating, ventilation, and air conditioning systems, and boilers) and elevators. In general, noise levels generated by such systems typically average between 55 and 85 dBA at 3 feet from the source (EPA 1971). Mechanical equipment is typically shielded from direct public exposure and usually housed on rooftops, within equipment rooms, or within exterior enclosures. As previously discussed, the nearest existing noise-sensitive land use in the vicinity of the Pleasanton parcel is the Wyndham Garden Hotel, located approximately 500 feet west of the project site. Given the distance to nearby existing noise-sensitive receptors, noise generated from the office and hotel uses would not result in an increase in exterior ambient noise levels at nearby existing noise-sensitive receptors. Assuming a maximum stationary source noise level of 85 dBA at 3 feet, projected operational noise levels at the proposed residential dwellings would be approximately 59 dBA, or less. W < ') PARKING STRUCTURES Parking-related noise typically includes vehicle exhaust, brake and tire squeal, the opening and closing of doors and trunks, and occasional car alarms. Maximum single-event noise levels associated with parking structures can reach approximately 92 dBA for short periods of time (FT A 1995). Predicted noise levels associated with the two parking facilities were calculated in accordance with FTA methodology for assessing noise levels generated by parking garages. Predicted noise levels were calculated based on the total number of parking spaces associated with each facility. Assuming that the facilities could be utilized by both day-shift and night-shift commuters, maximum average hourly traffic volumes generated by the parking garages would be approximately 80 vehicles per hour and 53 vehicles EDAW Noise 4.3-14 Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village .. .. ..i ..~ .

Based on tlle mod.elingc'onducted., t:he parking garage located on the Dublin parcel would generate noise levels of approximately 46 dBA CNEL at 50 feet from the structure. Noise levels generated by the parking garage located on the Pleasanton parcel would be approximately 42 dBA CNEL at 50 feet. As previously discussed, the nearest existing nOIse-sensitive land use in the vicinity of the Pleasanton parcel is the Wyndham Garden Hotel, located approximately 500 feet west of the project sit~.Noise'ie~elsg~nerated by the parking facilities would not exceed 6() d.BA CNEt or result in an increase in ambient noise levels at nearby existing noise-sensitive land uses. n t Bus SYSTEM TRANSIT CENTER Noise associated with bus transit centers typically includes exhaust and brake squeal from buses, the opening and closing of doors, and people talking. Maximum single-event noise levels associated with bus transit centers can reach approximately 101 dBA for short periods of time (FTA 1995). Predided noise levels associated with the bus transit center were calculated in accordance with FTA methodology. Predicted noise levels were calculated assuming a maximum average of 21 buses per hour, obtained from the current WHEELS (LivermoreAmador Valley Transit) schedule for the existing BART station (BART 2000). Based on the modeling conducted, the bus transit center would generate ~g~~~)\T~~.~L~RP:~ximately 6~~ACNEL at 50 feet from the structure. Assuming an average noise attenuation rate of 6 dBA per doubling of distance from the source, maximum projected transit center noise levels would be approximately 65 dBA CNEL at the proposed hotel and approximately 54 dBA CNEL at the proposed residential dwellings. COMBINED PROjECT-GENERATED AREA AND STATIONARY SOURCE NOISE r' I ' t Based on the modeling conducted for operational onsite noise levels associated with the proposed land uses, combined ext~rior~tationary source noise levels at the proposed hotel and residential dwellings are projected to be approximately 65 dBA and 60 dBA CNEL, respectively, not accounting for existing ambient noise levels. As previously discussed, ambient noise levels on the project site are dominated by traffic noise associated with vehicles traveling on 1-580 and typically average approximately 70-80 dBA cN',EL ., Operational noise levels associated with the proposed land uses would result in an imperceptible increase in ambient noise levels (i.e., less than 1 dBA) at the proposed onsite noise- sensitive receptors. Operational noise generated by the proposed onsite land uses would not result in a predicted increase in ambient noise levels at nearby existing noise-sensitive receptors. As a result, increases in on-site operational noise levels associated with the proposed land uses would be considered to have a less-than-significant impact on the existing noise environment. r r t f San Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Stafion and Transit Village 4.3-15 EDAW Noise dOS- lncreasesin Traffic Noise Levels on Area Roadwavs. The project generated traffic would not result in a noticeable increase (i.e., 3 dBA, or greater) in traffic noise levels at any existing noise-sensitive receptors. Therefore, this impact would be considered less than significant. Impact 4.3-3 The increase in daily traffic volumes resulting from development of the proposed project would generate increased noise levels along nearby roadways. The Federal Highway Administration's traffic noise prediction model (FHWA-RD-77-108) was used to calculate traffic noise levels along affected roadways for existing and existing plus project traffic conditions, based on the trip distribution estimates obtained from the traffic analysis prepared for this project. The existing traffic conditions are those that were present at the time this report was prepared. The existing plus project traffic conditions assume that the vehicle trips generated by the proposed project are added to the existing traffic conditions. See Section 4.5, Transportation/Circulation, for a discussion of the vehicle traffic generated by the proposed project. For traffic noise modeling purposes, development of the proposed project was estimated to generate a total of approximately 8,175 trips per day, obtained from the traffic analysis prepared for this project. The project's contribution to the existing traffic noise levels along area roadways was determined by comparing the predicted noise levels with and without project-generated traffic. Table 4.3-8 summarizes the calculated noise level at 50 feet from the centerline of the near travel lane for affected roadways located in the vicinity of potential noise-sensitive receptors. The roadway noise levels presented assumes no natural or man-made shielding between the roadway and the noise receptor. Based on the traffic modeling conducted, the proposed project would result in a maximum projected increase in traffic noise levels of 2 dBA, or less, along area roadways. As would be expected, predicted increases in traffic noise levels would be greatest along those segments providing direct access to the proposed project sites, which would include Golden Gate Drive and Stoneridge Mall Road. For the Dublin parcel, the predicted increase in traffic noise along Golden Gate Drive, between Dublin Boulevard and St. Patrick Way, would be approximately 2.0 dBA. Development of the Pleasanton parce~ would result in a predicted increase in traffic noise along Stoneridge Mall Road of approximately 1.5 dBA. Increases in traffic noise along the remaining nearby local roadway segments most affected by the proposed project would be approximately 0.6 dBA, or less. Based on the modeling conducted, increased traffic along area roadways associated with development of the proposed land uses would not result in a noticeable increase in ambient noise levels (i.e., 3 dBA, or greater) at any nearby existing noise-sensitive land uses.

Impact 4.3-4 Compatibility of the Proposed Land Uses with Projected On-site Noise Levels. Projected noise levels at the Dublin and Pleasanton parcels would exceed the "normally acceptable" thresholds established by each respective jurisdiction for the proposed land uses. As a result, this impact is considered significant. As previously discussed, existing noise levels on the Dublin and Pleasanton parcels are influenced primarily by traffic noise associated with vehicle traffic along 1-580 and, to a lesser extent, operation of the BART transit system located in the center median of the 1-580 corridor. Implementation of the proposed project would result in increased stationary source noise associated with the operation of the proposed land uses, as well as increases in traffic noise levels along area roadways associated with r San Francisco Bay Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 4.3-17 EDAW Noise a07 vehicles traveling to and from the proposed project. Combined on-site noise levels from all.existing and proposed noise-generating sources were analyzed to determine the compatibility of the proposed land uses with the noise criteria adopted by the respective jurisdictions. INTERSTATE-580 TRAFFIC NOISE Traffic noise levels associated with vehicles traveling on 1-580 were calculated using the Federal Highway Administration's Traffic Noise Model(FHWA-PD-96-009). The calculation of projected vehicle traffic noise levels was based on the average daily vehicle trips obtained from the traffic analysis prepared for this project. Projected traffic noise levels assume no noise shielding from intervening terrain or manmade structures (i.e., berms, concrete barriers, buildings, etc.). Under existing conditions, vehicles traveling on 1-580 would result in noise levels of approximately 84 dBA CNEL at 50 feet from the centerline of the near travel lane. With the addition of project-generated traffic, the noise level from vehicles traveling on 1-580 would remain at 84 dBA CNEL. The noise level would remain unchanged due to the very small percentage of project-generated traffic in relation to existing vehicle traffic on 1-580. ON-SITE TRANSIT NOISE LEVELS Noise generated by the passby of BART trains was assessed in accordance with the U.S. Department of Transportation, Federal Transit Administration (FTA) recommended methodology obtained from Transit Noise and Vibration Impact Assessment Guidelines (1995). The estimation of transit noise levels was based on a combined total of approximately 148 eastbound and westbound commute trains during a typical weekday, and assumed an average of 10 cars per train and an average departure/arrival speed of 30 miles per hour near the proposed station (BART, 1989). Based on the analysis conducted, wayside transit noise was calculated at 65.5 dBA CNEL at 50 feet from the near track centerline in the vicinity of the proposed station. PROJECTED ON-SITE NOISE CONTOURS Noise contours at the Dublin and Pleasanton parcels were calculated based on the predicted vehicle traffic and transit noise levels, as calculated above, and in combination with projected operational noise levels associated with the proposed land uses. The projected ambient noise levels at each of the proposed noise-sensitive land uses are summarized in Table 4.3-9. This table also identifies the land use compatibility thresholds of each jurisdiction. The compatibility of the proposed land uses with projected noise levels are discussed separately for each parcel, as follows.

Projected traffic volumes were obtained from the traffic analysis prepared for this project and assume that peak hour volumes are ten percent of the average daily volumes. 1 Land use compatibility thresholds are based on the general plan criteria adopted by each respective jurisdiction, as previously identified in Tables 4.3-2 and 4.3-3. Source: EDAW 2000. r . DUBI.INP AltCEL As depicted in Table 4.3-9, projected noise levels at the proposed hotel and residential development located on the Dublin parcel would exceed the "normally acceptable" land use compatibility threshold of 60 dBA CNEL. Projected noise levels at the lower level of the proposed hotel would be approximately 79 dBA CNEL due primarily to vehicle traffic on 1-580. Projected noise levels at the proposed residential development would be nearly 69 dBA at the residential units located along Golden Gate Drive. Although the proposed hotel would provide partial shielding of traffic and transit-related noise from the 1-580 corridor, projected exterior noise levels along the southern perimeter of the proposed.'r~sidenti~ development wouldstill exceed 60 d'BA. Because projected noise levels would exceed the "norm~y acceptable" exterior noise threshold of 60 dBA CNEL established by the City of Dublin for the proposed land uses, this impact is considered significant. 'PLEASANTON PARCEL As with the Dublin parcel, exterior noise levels at the Pleasanton site would be influenced primarily by ~ehicl~traffic on 1:580. Based()n the modeling conducted, maximum combined. exterior noise levels would be approximately 78 dBA CNEL along the northern edge of the proposed office building (Table fl Son Francisco Bay Area Rapid Transit District ,. WestOublin/Pleasanton BART Station and Transit Village 4.3-19 EDAW Noise ;}.01 .. 4.3-8). Projected exterior noise levels along the southern facade of the office building that fronts Stoneridge Mall Road would be less than 65 dBA CNEL. Maximum projected noise levels at the northern edge of the proposed office building would exceed 70 dBA CNEL. Because projected noise levels would exceed the "normally acceptable" exterior noise compatibility threshold established by the City of Pleasanton for the proposed land use, this impact is considered significant. 4.3.3 MITIGATION MEASURES Noise from Construction Activities. < Noise-generating activities associated with construction of the proposed land uses shall be limited to daytime hours of operation Monday through Saturday. Mitigation 4.3-1 All construction vehicles or equipment, fixed or mobile, would be equipped with properly operating and maintained mufflers and acoustical shields or shrouds, in accordance with manufacturers' recommendations. Stationary noise-generating construction equipment (e.g., generators, cranes, compressors, and mixers) would be centrally located on the project site or within equipment staging areas at the greatest distance possible from occupied building(s) To the maximum extent possible, construction of the proposed land uses shall be phased to minimize the occurrence of construction activities after completion and occupancy of the proposed noise-sensitive land uses on the Dublin parcel (i.e., the residential dwellings and hotel). Com1Jatibilitv of Pro1Josed Land Uses with Projected Noise Levels. The following mitigation measures are proposed to reduce interior noise levels of the proposed land uses: Mitigation l 4.3-4 The developer shall utilize an acoustical professional, such as a Licensed Engineer or Licensed Architect with experience in acoustics. The acoustician shall develop noise attenuation measures to be incorporated into the design and construction of the proposed residential, hotel, and office building that will produce a composite building sound transmission control (STC) rating of 30 (or higher) individually computed for the walls and for the floor/ceiling construction. Suggested measures include: wall construction with resilient channels, staggered studs, or double-stud walls, use of dual glazed windows with laminated glass, limitation of the number and size of windows along walls located within close proximity to major noise sources, and ensuring that all exterior construction joints are either grouted or caulked air-tight. Additional measures include locating on-site stationary noise sources (i.e., EDAW Noise 4.3-20 Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village ~ .. .. , ""t .

Title 24 of the California Code of Regulations requires the preparation of an acoustical analysis for multi-family residences that demonstrates how interior noise levels will achieve a 45 dBA CNELjLdn' where the exterior noise levels exceed 60 dBA CNELjLdn' As a result, a Title 24 analysis shall be prepared as part of the fmal design of the proposed residential dwellings. To the extent necessary, noise control measures shall be designed according to the type of building construction and specified sound rating for each building element to achieve an interior noise level of 45 dBA CNELjLdn' 4.3.4 LEVEL OF SIGNIFICANCE AFTER MITIGATION NOISE FROM CONSTRUCTION ACTIVITIES r r . Implementation of the proposed mitigation measures for the control of short-term construction- generated noise would include provisions for the use of exhaust muffiers and engine shrouds (in accordance with manufacturers' recommendations ) and would reduce the potential for activities occurring during the more noise-sensitive evening and nighttime hours. The use of equipment mufflers and shrouds would reduce individual equipment noise levels by approximately 5 to 10 dBA and would reduce total construction-generated noise levels to approximately 85 dBA, or less, at 50 feet from the construction site. With implementation of the proposed mitigation measures, increases in average daily ambient noise levels would be reduced to less than 3 dBA at existing nearby noise-sensitive receptors. However, should onsite construction activities occur after completion and occupancy of the proposed hotel or residential land uses, noise levels would be in excess of 70 dBA and increases in ambient noise levels would exceed 3 dBA even with implementation of the proposed mitigation measures at these buildings. Projected increases in ambient noise levels would be limited to the construction phase of the proposed project and would be dependent on the specific activities being performed. However, because noticeable increases in ambient noise levels above the significance thresholds at the hotel and residential buildings may still occur, even with implementation of the proposed mitigation measures, this impact is considered significant and unavoidable. No additional and feasible mitigation is available to reduce this impact to less-than-significant levels at the hotel and residential buildings. r ~ COMPATIBILITY OF PROPOSED LAND USES WITH PROJECTED NOISE LEVELS Implementation of the proposed mitigation measures would ensure that interior noise levels at the proposed hotel on the Dublin parcel are reduced to acceptable levels, in accordance with the CIty of Dublin's land use compatibility thresholds.

These factors are discussed below, together with the current regulatory structure that applies to the San Francisco Bay Area Air Basin pursuant to the regulatory authority of the Bay Area Air Quality ManagemeritDistrict (BAAQMD). r- ~ Climate And Meteorology r t .' , Ambient air quality is commonly characterized by climatological conditions, the meteorological influences on air quality, and the quantity and type of pollutants released. The basin is subject to a combination of topographical and climatic factors that reduce the potential for high levels of regional and local air pollutants. The following section describes pertinent charact"eristics of the air basin and provides an overview of the physical conditions affecting pollutant dispersion in the project area. ,....... Ii --- t ~ . REGIONAL CLIMATE ""'"' f . r; . The project site is located in the eastern portion of the San Francisco Bay Area Air Basin (Basin), an area encompassing all of Marin, Napa, Contra Costa, Alameda, Santa Clara, San Mateo, San Francisco, and parts of Sonoma and Solano counties. The basin is characterized by a complex terrain consisting of coastal mountain ranges, inland valleys, and the San Francisco Bay. It is generally bounded on the west by the Pacific Ocean, on the north by the cC>aStRanges, aJ:1d'on the east alld ~outh by the Diablo Range. r r I The Basin climate is dominated by the strength and location of a semipermanent, subtropical high- pressure cell over the northeastern Pacific Ocean. Climate is also affected by the moderating effects of the adjacent oceanic heat reservoir.

Precipitation varies greatly in the project area, depending on season. Rainfall averages approximately 14.2 inches annually and occurs almost exclusively from October through April. Summers are mild and relatively dry with 3 to 4 months without rain while conditions in the bay produce periodic fog during the morning. Winters are mild and intermittently rainy. Winds across the smdy area are an important meteorological parameter because they control the dilution of locally-generated air pollutant emissions and their regional trajectory. Southwest winds are the most common at the Livermore Station, the closest station that measures wind speed and direction to the proposed project. However, in the winter, northeast winds prevail and in the summer, west winds are the most frequent. Long-term wind data recorded at the Livermore Station indicates that daily winds average 4.4 mph with west winds typically averaging 5.1 mph (California Air Resources Board 1992). METEOROLOGICAL INFLUENCES ON Am QUALITY Regional flow patterns affect air quality patterns by directing pollutants downwind of sources. Localized meteorological conditions, such as moderate winds disperse pollutants and reduce pollutant concentrations. When a warm layer of air traps cooler air close to the ground, an inversion layer is produced. Such temperature inversions hamper dispersion by creating a ceiling over the area and trapping air pollutants near the ground. During summer mornings and afternoons, these inversions are present over the project area. During summer's longer daylight hours, plentiful sunshine provides the energy needed to fuel photochemical reactions between nitrogen oxides (NOx) and reactive organic gases (ROG), which result in ozone (03) formation. In the winter, temperature inversions dominate during the night and early morning hours but frequently dissipate by afternoon. During the winter months, the greatest pollution problems are from carbon monoxide (CO) and NOx' High CO concentrations occur on winter days with strong surface inversions and light winds. Carbon monoxide transport is extremely limited. CRITERIA Am POLLUTANTS Currently, most of the effort to improve air quality in the United States and California is directed toward the control of five pollutants, called "criteria" air pollutants: photochemical oxidants (ozone), CO, PM10, N02, and sulfur dioxide (S02)' Fifteen years ago, suspended particulate lead would have been included in this list, but the widespread availability and use of unleaded gasoline has effectively eliminated lead EDAW Air Quality 4.4-2 Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village .. iii . .

Criteria pollutants, including their formation and healtli effects, are discussed below: Ozone r, , Ozone (03) is a colorless gas with a pungent odor that causes eye irritation and respiratory function impairment. Most 03 in the atmosphere is formed as a result of the interaction of ultraviolet light, ROG, and NOx' ROG is composed of non-methane hydrocarbons, and NOx consists of chemical combinations of nitrogen and oxygen, mainly NO and NOz. Motor vehicles are the primary source of ROG and NOx' Because these photochemical reactions are regional in nature, 03 is considered a regional pollutant. Fine Particulate Matter (PM1o) r- r' PMlO are atmospheric particles resulting from fume-producing industrial and agricultural operations, and natural activities. Health impacts from breathing the particulates resulted in revision of the Total Suspended Particulate (TSP) standard to reflect particulates that are small enough to be inhaled (i.e., 10 microns or less in size). Current standards defIne acceptable concentrations of particulates that are smaller than 10microns in diameter, referred to as PMlO. PMlO includes materials such as sulfates and nitrates, which can cause lung damage. ,...... t ~ r Carbon Monoxide \r , \ Carbon monoxide (CO) is an odorless, colorless gas that causes a number of health problems including fatigue, headache, confusion and dizziness. The incomplete combustion of petroleum fuels in on-road vehicles is a major cause of CO. CO is also produced during the winter from wood stoves and fIreplaces. CO tends to dissipate rapidly into the atmosphere; consequently, violations of the CO state standard are generally limited to major intersections during peak hour traffic conditions. Nitrogen Dioxide r-c , ' Nitrogen dioxide (NOz) is an indirect product of fuel combustion in industrial sources, motor vehicles, and other mobile sources (e.g., off-road vehicles, trains, aircraft, mobile equipment, and utility equipment). NOz causes a number of health problems including risk of acute and chronic respiratory disease. Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 4.4-3 EDAW Air Quality :;JiS- .. Sulfur Dioxide . The major source of S02 emissions is fuel-burning equipment in which fuel oil and/or coal are consumed. S02 causes a number of health problems including aggravation of chronic obstructive lung disease. 1.1I . REGULATORY SETTING OF AIR QUALITY 'il - Air quality is regulated by several jurisdictions including the U.S. Environmental Protection Agency (USEPA), California Air Resources Board (CARE), and the BAAQMD. Each of these jurisdictions develop rules, regulations, policies, and/or goals to attain the goals or directives imposed upon them through legislation. Although USEP A regulations may not be superseded, both state and local regulations may be more stringent. IIlii . Pollutants subject to federal ambient standards are referred to as "criteria" pollutants because the USEP A publishes criteria documents to justify the choice of standards. One of the most important reasons for air quality standards is the protection of those members of the population who are most sensitive to the adverse health effects of air pollution, termed "sensitive receptors." The term sensitive receptors refers to specific population groups, as well as the land uses where they would reside for long periods. Commonly identified sensitive population groups are children, the elderly, the acutely ill, and the chronically ill. Commonly identified sensitive land uses are residences, schools, playgrounds, childcare centers, retirement homes or convalescent homes, hospitals, and clinics. The federal and state standards for the criteria pollutants and other state regulated air pollutants are shown in Table 4.4-1. . . .. .. FEDERAL Am QUALITY REGULATIONS till At the federal level, the USEP A has been charged with implementing national air quality programs. The USEP A's air quality mandates are drawn primarily from the Federal Clean Air Act (FCAA), which was signed into law in 1970. Congress substantially amended the FCAA in 1977 and again in 1990. . . The FCAA required the USEP A to establish National Ambient Air Quality Standards (NAAQS), and also set deadlines for their attainment. Two types ofNAAQS have been established: primary standards, which protect public health, and secondary standards, which protect public welfare from non-health- related adverse effects, such as visibility restrictions. .. . .

On May 14, 1999, the U.S. Court of Appeals for the District of Columbia put a hold on implementing the 8-hour ozone standard and asked for further comments on the fine particulate (PM2.5) standard. These standards are currently under review. ppm = parts per million by volume Jlg/m3 = micrograms per cubic meter Source: California Air Resources Board 2000 ,..... , I- ~ , - t f ..-- , , r- \ Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Village 4.4-5 EDAW Air Ouolity :;J )1 STATE AIR QUALITY REGULATIONS The California Clean Air Act (CCAA), 1988, requires that all air districts in the state endeavor to achieve and maintain California Ambient Air Quality Standards (CAAQS) for 03, CO, SOz, and nitrogen dioxide (NOz) by the earliest practical date. Plans for attaining CAAQS were to be submitted to CARE by June 30, 1991. The CCAA specifies that districts focus particular attention on reducing the emissions from transportation and area-wide emission sources, and the act provides districts with authority to regulate indirect sources. Each district plan is required to either (i) achieve a 5% annual reduction, averaged over consecutive 3-year periods, in district-wide emissions of each non-attainment pollutant or its precursors, or (ii) to provide for implementation of all feasible measures to reduce emissions. Any planning effort for air quality attainment would thus need to consider both state and federal planning requirements. The California Air Resources Board (CARE) is the agency responsible for coordination and oversight of sate and local air pollution control programs in California and for implementing the California Clean Air Act (CCAA) of 1988. The CCAA requires that all air districts in the state endeavor to achieve and maintain California Ambient Air Quality Standards (CAAQS) for 03, CO, SOz, and nitrogen dioxide (NOz) by the earliest practical date. Plans for attaining CAAQS were to be submitted to CARB by June 30, 1991; however, some districts are still in the draft process. The CCAA specifies that districts focus particular attention on reducing the emissions from transportation and area-wide emission sources, and the act provides districts with new authority to regulate indirect sources. Each district plan is to achieve a 5 percent annual reduction, averaged over consecutive 3-year periods, in district-wide emissions of each non attainment pollutant or its precursors. Any additional development within the region obviously would impede the reduction goals of the CCAA. Other CARE duties include monitoring air quality (in conjunction with air monitoring networks maintained by air pollution control districts (APCDs) and Air Quality Management Districts (AQMDs), establishing CAAQS (which in many cases are more stringent than the NAAQS), and setting emissions standards for new motor vehicles. The emission standards established for motor vehicles differ depending on various factors including the model year, and the type of vehicle, fuel and engine used. The CARE has recently adopted new diesel exhaust control measures and more stringent emission standards for various on-road mobile sources of emissions, including transit buses. In February 2000, the CARE adopted a new public transit bus fleet rule and emission standards for new urban buses. These new rules and standards provide for 1) more stringent emission standards for some new urban bus engines beginning with 2002 model year engines; 2) zero-emission bus demonstration and purchase EDAW Air Quality 4.4-6 Son Francisco Boy Area Rapid Transit District West Dublin/Pleasanton BART Station and Transit Villagen '~ .. . . . till .>j ..

BAY AREA AIR QUALITY MANAGEMENT DISTRICT REQUIREMENTS The BAAQMD is responsible for implementing emissions standards and other reqUirements of federal and state laws regarding most types of stationary emission sources. The BAAQMD regulates air quality in the local area through its permit authority and its planning and review activities. .In an effort to reach attainment of the state standards for 03 as required by the CCAA, the BAAQMD completed its Bay Area '97 Clean Air Plan (CAP). The CAP stresses attainment of 03 standards and focuses on strategies reducing NOx and ROG air emissions by promoting active public involvement, by encouraging compliance through positive influence and behavior, public education m both the public and private sectors, and implementation of stationary and mobile source control measures (BAAQMD 1997). An update of the CAP is expected to occur in 2000, and a workshop draft of the updated CAP has been released. To attain the federal I-hour standard for 03, the San Francisco Bay Area Ozone Attainment Plan was adopted by the BAAQMD in June 1999. The plan includes measures already included in the CAP and identifies additional strategies to control emissions from stationary and area sources of emissions. In addition, the plan includes two voluntary measures, including the Spare the Air Program (1999 and 2000 ozone season only) and low emission alternatively fueled vehicles and infrastructure (BAAQMD 1999). EXISTING AIR QUALITY MONITORING DATA Air pollutant concentrations are measured at monitoring stations throughout the Basin. Baseline air quality in the study area can be inferred from ambient air quality measurements conducted at the monitoring station located in Livermore. This is the closest station to the project site and is considered generally representative of the air quality in the Dublin and Pleasanton area. However, because ambient air quality can vary within the tri-valley area depending on location, caution should be taken when extrapolating these measurements to describe pollutant levels in the Dublin and Pleasanton areas. Wa.ple 4.4-2 summarizes the last 4 years of published data available for this monitoring station.

Son Francisco Boy Area Rapid Transit District West DublinlPleasanton BART Station and Transit Village Ii ;)ao EXISTING ATTAINMENT STATUS Monitored criteria air pollutants are classified in each air basin, county, or iI1 some cases within a specific urbanized area. The classification is determined by comparing actual monitoring data with state and federal standards. If a pollutant concentration is lower than the standard, the pollutant is classified as "attainment" in that area. If an area exceeds the standard, the pollutant is classified as "non-attainment." If data ;lre inst1fficient to determine whether or not the standard is exceeded, the area is designated "unclassified. " The Basin is considered a non-attainment area for the State and federal I-hour 03 standard, and a nonattainment area for the state PMlO standards (BAAQMD 2000). 4.4.2 ENVIRONMENTAL IMPACTS THRESHOLDS OF SIGNIFICANCE r-- ,i I For the purposes~f~~31ysis,t:he:BayAreaAir QualityManagem~rlt:District (BAAQMD) thresholds of significance are used to determine whether the project would result in a significant air quality impact. Using the BAAQMD'sCEQA Guidelines (April 1996), significant air quality impacts are identified as follows: ~ Construction Impacts. Project impacts would be considered significant if feasible BAAQMD construction control mitigation measures listed in the BAAQMD CEQA Guidelines are not incorporated. .~ · Regional Impacts. Project emissions would be considered significant at a regional level if the restliting emissions of ROG, NOx, or PM10 exceed 15 tons per year, 80 pounds per day, or 36 kilograms per day. · Localized CO Impacts-Roadways. Project CO concentrations would be considered significant if a project contributes to CO concentrations exceeding the State Ambient Air Quality Standard of9.0 parts per million (ppm) averaged over 8 hours or 20 ppm for 1 hour. · Localized Cf(JBnp~~ts-Pa;king Garages. Th~re are currently no agreed upon indoor air quality standards for CO (EP A 2000). However, maximum permissible exposure limits for CO have been established by various agencies, including the Occupational Safety and Health Administration (OSHA), the American Conference of Governmental Industrial Hygienists (ACGIH), and the Mine Safety and Health Administration (MSHA). The maximum permissible CO concentration established by OSHA and ACGIH is 50 ppm averaged over an 8-hour period. The interior CO concentration level established by the MSHA is 35 ppm for an r ~ ' Son Francisco Boy Area Rapid T ronsit District West DublinlPleasonton BART Station and Tronsit Village 4.4-9 EDAW Air Quality d-:;>..I 8-hour period (OSHA 2000). For purposes of this analysis, interior CO concentrations within the parking garages would be considered significant if levels would exceed the more stringent exterior State Ambient Air Quality Standard of 9.0 parts per million (ppm) averaged over 8 hours or 20 ppm for 1 hour. PROJECT IMPACTS Construction activities associated with the proposed project would temporarily generate short-term emissions of NO x, ROG, CO, and PMlO during clearing/demolition, grading, and general construction activities. The emissions produced during clearing/demolition, grading, and general construction activities are "short-term" in the sense that they would be limited to the construction period, and would only be experienced downwind of the project site. The entire construction process is anticipated to last approximately 2 years. Emissions would be generated during land clearing and grading activities associated with preparing the soil for the proposed land uses and the various utility improvements (water supply, storm drainage, sanitary sewer, wastewater treatment system, and electrical/natural gas infrastructure). Air pollutant emissions would also be generated from paving, framebuilding, and other construction activities associated with building development. The construction emissions generated by the proposed project would be considered a short-term significant air quality impact. Impact 4.4-1 I.. Impact 4.4-2 Construction-Related Air Emissions. Construction activities associated with the proposed project would temporarily produce emissions of NOx, ROG, CO, and PM10" Emissions would va.ry substantially from day to day and could potentially produce substantial amounts of PM10, These construction emissions would be considered a short-term significant air quality impact. Localized CO Concentrations-Area Roadwavs. Occupation of the proposed project would increase CO concentrations at nearby intersections due to increased vehicular traffic to and from the project site. However, predicted CO concentrations at affected intersections would not exceed state or federal ambient air quality standards. Therefore, this is considered a less-than-significant impact. The primary mobile source pollutant of local concern is carbon monoxide (CO). Emissions of ROG, NOx, and PMlO are considered regional emissions of concern and are analyzed at a regional level in accordance with BAAQMD CEQA Guidelines. Carbon monoxide concentration is a direct function of vehicle idling time and, thus, traffic flow conditions. Carbon monoxide transport is extremely limited; it disperses rapidly with distance from the source under normal meteorological conditions. Under certain meteorological conditions, however, CO concentrations close to a congested roadway or intersection may reach unhealthy levels, affecting local sensitive receptors (residents, school children, hospital patients, the elderly, etc.). As a result, the BAAQMD recommends analysis of CO emissions EDAW Air Quolity 4.4-10 Son Francisco Boy Area Rapid Transit District West DublinlPleasanton BART Station and Transit Village . iii III ,,; . .. :ii . ..

Typically, areas of high CO concentrations, or "hot spots," are associated with roadways or intersections operating at high levels of service (LOS E, or worse). In areas with a high ambient background CO concentration, modeling of CO concentrations at affected intersections is recommended in determining a project's effect on local CO levels. Predicted CO concentrations at affected intersections were calculated in accordance with BAAQMD- recommended screening methodology, as identified in theBAAQMD CEQA Guidelines (1996), which is based on the EP A-approved CALINE4 dispersion model. Maximum worst-case CO concentrations were calculated for existing conditions, existing plus approved development conditions, and existing plus approved plus project conditions. Based on the fmdings of the traffic analysis and in accordance with BAAQMD-recommended methodology, predicted CO concentrations were modeled at intersections projected to operate at a LOS E, or worse, during the p.m. peak hours. Predicted CO concentration modeling results are presented in Table 4.4-3. As indicated in Table 4.4-3, increased vehicle traffic associated. withi.rllplemen.i:itio;} of the proposed land uses would not result in or contribute to CO concentrations in excess of the state or national standards. .As a result, this impact would be consIdered less-than-sIgnificant. Localized CO Concentrations-Proposed Parkin$! Structures. Operation of the proposed project would result in CO concentrations within the proposed parking garages. However, projected CO concentrations would not exceed applicable thresholds. As a result, this impact would be less than significant. Impact 4.4-3 Operation of the proposed project would result in CO concentrations within the proposed parking garages. The proposed parking garages would include vehicles traveling and idling within the facility and would have the potential for internal air quality impacts~ Because all vehicles, regardless of where they park, must enter or exit from the ground floor, carbon monoxide emissions would be greatest on the ground floor of the garage. The CAL3QHC Dispersion Model was used to calculate the maximum CO concentrations within the parking garages. The CAL3QHC model is the model recommended by the U.S. EP A for the estimation of local and mobile source CO concentrations.

Actual CO concentrations within the proposed parking structures would likely be . less than those indicated in Table 4.4-4. Predicted CO concentrations within parking garages would not exceed the interior air quality standard of 50 ppm for 8-hour CO concentrations established by the Occupational Safety and Health Administration and the American Conference of Governmental Industrial Hygienists. In addition, predicted worst-case CO concentrations within both parking facilities would not exceed the State Ambient Air Quality Standard of9.0 ppm averaged over 8 hours or 20 ppm for 1 hour. As a result, localized CO concentrations within the proposed parking structures would not be anticipated to pose a health risk to nearby receptors and, as a result, would be considered to have a less-than-significant air quality impact. Impact 4.4-4 ReJdonal Air Qualitv Impact. The proposed project would generate, regional emissions primarily associated with increased vehicle use related to the transit village uses. Additional emissions associated with the use of natural gas-fired appliances, landscape maintenance equipment, and consumer products would also be generated. However, approval of the proposed project would facilitate construction of the approved West Dublin/Pleasanton BART Station. The use of this new BART Station would substantially reduce automobile travel on the local roadway network by providing a public Transportation option for commuters. The result would be a net reduction in regional emissions. Therefore, this impact would be considered less than significant. Emissions from motor vehicle operations associated with the transit village uses would represent a long- term air quality impact associated with development of the proposed project. The use of landscape ". maintenance equipment, natural gas-fired appliances, and consumer products (e.g., cleaners, solvents, ete.) would generate additional emissions of regional pollutants. However, approval of the proposed transit village uses would facilitate construction of the approved West DublinjPleasanton BART Station. The use of this new BART Station would substantially reduce automobile travel on the local roadway network by providing a public transportation option for commuters. The result would be a net reduction in regional emissions. Son Francisco Boy Area Rapid Transit District West DublinlPleosanton BART Station and Transit Village 4.4-13 EDAW Air Quality ;).:;;t;- The urban emission model, URBEMIS7G, was used to predict quantities of NOx, ROG, and PMlO emissions generated by mobile and area sources. The URBEMIS7G default assumptions and emissions factors for the San Francisco area were used for the calculation of emissions associated with the use of motor vehicles, landscape maintenance equipment, natural gas-fired appliances, and consumer products. Trip generation rates for the proposed transit village land uses were adjusted to correspond with the projections presented in the traffic analysis prepared for this project. The proposed transit village uses would also result in emissions of CO. However, because CO disperses rapidly with increased distance from the source, emissions of CO are considered localized pollutants of concern rather than of regional concern. Refer to Impacts 4.4-2 and -3 for analysis of CO emissions. Based on the modeling conducted, the transit village uses would generate annual mobile source emissions of approximately 10.65 tons of ROG, 18.08 tons of NO x, and 5.83 tons ofPM1o' The use of landscape maintenance equipment, natural gas-fired appliances, and consumer products would generate additional emissions of approximately 1.5 tons of ROG and 0.6 tons of NOx' Combined emissions associated with both indirect and direct sources associated with the transit village uses would be 12.17 tons of ROG, 18.69 tons of NO x, and 5.83 tons ofPMlO. The DPX EIR concluded that with implementation of the DPX Project, a net reduction in regional vehicle miles traveled would be anticipated due to the removal of automobiles from regional freeways and roads. The DPX EIR estimated that the total reduction in automobile travel with the DPX Project would be 44.78 million vehicle miles per year. For buses, the total reduction in vehicle miles was estimated at 6.95 million vehicle miles per year. The DPX ErR concluded that with implementation of the DPX Project, a net reduction in regional emissions would be anticipated. The reduction in automobile travel resulting from the implementation of the West Dublin/pleasanton BART Station would be approximately 25.6 million vehicle miles per year. This estimate was obtained by multiplying the number of passenger vehicles removed from the regional roadway network due to the availability of BART service times the estimated average trip length for those removed vehicles. First, to determine the number of passenger vehicles that would be removed from the regional roadway network with the BART Station, the estimated total number of daily BART passengers expected at the station was identified for the year 2010. This total is estimated to be 5,736 passengers. Of this total, approximately 21.5 percent, or 1,233 passengers, are estimated to be generated from the proposed transit village uses. Because these passengers would represent new BART trips generated by the proposed project, rather than BART trips substituted for automobile trips, they were removed from the total. Of the remaining 4,503 daily passengers, approximately 25.7 percent, or 1,157, are estimated to access the station by non-passenger vehicle modes including walking, buses, bicycle, etc. The remaining EDAW Air Quality 4.4-14 Son Francisco Bay Area Rapid Transit District West DublinlPleasanton BART Station and Transit Village .. ,,~ II ..

As a result, development of the proposed project is not anticipated to conflict with the projection contained in the Bay Area '97 Clean Air Plan. This impact is considered less than significant. 4.4.3 MITIGATION MEASURES Construction activities associated with the proposed project would result in significant short-term air quality impacts. To mitigate this impact, applicable BAAQMD Basic and Enhanced Control Measures shall be implemented during construction. Specific controls to be implemented include the following: Mitigation 4.4-1 · Water all active construction areas at least twice daily. . Cover all trucks hauling soil, sand, and other loose materials or require all trucks to maintain at least two feet of freeboard. . Pave, apply water three times daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas and staging areas at construction sites. . Sweep daily (with water sweepers) all paved access roads, parking areas and staging areas at construction sites. . Sweep streets daily (with water sweepers) if visible soil material is carried onto adjacent public streets. . Hydroseed or apply (non-toxic) soil stabilizers to inaci:ive construction areas. . Enclose, cover, water twice daily or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.). · Limit traffic speeds on unpaved roads to 15 mph. · Install sandbags or other erosion control measures to prevent silt runoff to public roadways. . Replant vegetation in disturbed areas as quickly as possible. The use of watering twice daily for dust control in construction areas is estimated to reduce dust emissions by at least 37 percent. Covering haul truck loads or maintaining at least 2 feet of freeboard is estimated to reduce dust emissions by approximately 1 to 2 percent. Paving or applying water twice daily to haul roads is estimated to reduce dust emissions by approximately 3 to 7 percent. Enclosing, covering, or watering soil piles twice daily can reduce dust emissions by 1.6 percent. To reduce the demand for water associated with regular watering of the project site, an appropriate dust palliative or suppressant could be used as an alternative.

The study approach was to determine if any nearby intersections are projected to operate at worse than Level of Service (LOS) D and to determine what mitigation measures would be necessary if these levels of service standards are exceeded. In addition, site access and circulation, and parking impacts are evaluated. Exhibit 4.5-1 illustrates the regional roadway network surrounding the project site. Fifteen study intersections in Dublin and twelve study intersections in Pleasanton, shown on Exhibit 4.5-2, were evaluated. STUDY AREA ROADWAY NETWORK Important roadways serving the project area are discussed below. Regional Roadways Interstate 580 (1-580) is an eight-lane east-west freeway that connects Dublin, Pleasanton and Livermore, as well as regional origins and destinations such as Oakland, Hayward and Tracy. In the vicinity of the proposed project, I-5802u-ries approXinJ.~t:ely 178,000 vehicles per day (vpd) (Caltrans, 1999). The interchange at San Ramon RoadjFoothill Road in the project area is planned to be reconfigured from a four-quadrant cloverleaf interchange to a pamaf Cloverleaf interchange in the future. A project study report (PSR) for the interchange is currently in preparation. Interstate 680 (1-680) is a six-lane freeway in the vicinity of the project site. 1-680 carnes approximately 126,000 vpd and 136,000 vpd between Stoneridge Drive and Alcosta Boulevard (Caltrans, 1999). A future interchange at West Las Positas Boulevard is under study at this time by the City of Pleasanton. In addition, new southbound on-off hook ramps are currently under construction at Amador Plaza Road in Dublin. A new northbound on-ramp was recently opened to traffic in the same area. The I-680jI-580 southbound to eastbound direct connector (flyover) project is under construction and is scheduled for completion in 2003.

PLANNED REGIONAL ROADWAY IMPROVEMENTS The study assumes that key regional roadway improvements will be completed in the near-term future by 2010. These are listed below. San Ramon RoadjFoothill Road Interchange - The interchange at San Ramon Road is planned to be reconfigured from a four-quadrant cloverleaf interchange to a partial cloverleaf interchange. The new configuration is assumed to be built under the Existing plus Approved Conditions. Full funding for this project will come from the Tri -Valley Transportation Council's Traffic Improvement Fee. The City of Dublin is the lead agency in a current effort to prepare a Project Study Report. This project is estimated to be constructed within the next five years. Interstate 680jAmador Plaza RoadfVillage Parkway Interchange - New hook ramps are currently under construction in Dublin at Amador Plaza Road for the southbound on and off-ramps. A new northbound on-ramp was recently completed at Village Parkway. A northbound off-ramp is not proposed. Currently, Amador Plaza Road forms aT-intersection with St. Patrick Way where the fourth leg of the intersection will be the southbound ramps. The northbound on-ramp is now open to traffic and construction should be completed on the southbound ramps within the next two years. .. .. . .. . . .. . .. . .. .. . . III ..

The parking areas east of Amador Plaza Road in the vicinity of the Good Guys,Rigattoni's Restaurant and Bank of America were observed to be full. However, the parkinglot on the west side of Amador Plaza Road, north of St. Patrick Way, serving Big 5, Mattress Discounters, Jennifer Convertible and Son Francisco Boy Area Rapid Transit District West DublinlPleosanton BART Station and Transit Village 4.5-9 EDAW T ransportationlCirculation ,.... ! f ;J3"1 other retail uses appeared to be about 30 percent full during the peak hour. For this parking area, about 35 spaces were occupied out of approximately 120 spaces. The parking lot south of St. Patrick Way serving Super Crown and Tower Records was observed to be full. In addition, the parking lot at the end of Amador Plaza Road leading to office space, including Micro Dental, was full. On-street parking along Amador Plaza Road is prohibited, except at the end of the road in the court, where the on-street parking was full. There are sidewalks on both sides of the street. Currently, St. Patrick Way connects Amador Plaza Road and Golden Gate Drive. On-street parking on St. Patrick Way is prohibited. Besides the two retail strips accessible from Amador Plaza Road, St. Patrick Way does not provide access to other off-street parking lots for public use. There are sidewalks on both sides of St. Patrick Way. Golden Gate Drive provides access to office uses and an automobile dealership. Private parking lots for these uses are provided and were observed to be full. On-street parking is permitted on Golden Gate Drive, and was also observed to be full. Sidewalks are provided on both sides of the street. Regional Street provides access to retail, office, and restaurant uses. The parking lot that serves Starbucks Coffee and other retail, located on the northwest corner of Dublin Boulevard and Regional Street, was observed to be full. The parking lot serving Burger King, Michael's, Ross Dress For Less, Orchard Supply Hardware, MarshaUs, and other retail, was observed to be about 60 to 70 percent full during the peak hour. The parking lot designated for the Best Western Monarch Hotel was about 50 percent occupied, with the majority of vacant spaces located behind the building. The parking spaces adjacent to the Outback Steakhouse were mostly empty (about 90 percent) since this restaurant is not opened on weekdays until 4:00 p.m. The parking for the Willow Tree Restaurant was observed to be partially occupied (30 percent) with vacant spaces in the rear of the restaurant. Parking adjacent to the Dublin Bowl was mostly empty; whereas parking spaces across the lot near the office buildings were full. On-street parking is permitted for sections of Regional Street with restrictions for vehicles over 20 feet in length. On-street parking was observed to be available. There are sidewalks on both sides of the street. In summary, existing parking in the immediate area of the proposed project on Golden Gate Drive appears to be full during the peak weekday parking hour for retail and office uses. Parking appears to be more available near Regional Street and in certain parking lots of Amador Plaza Road. There are sidewalks on Amador Plaza Road, St. Patrick Way, Golden Gate Drive, and Regional Street, and crosswalks on Dublin Boulevard at the intersections of Amador Plaza Road, Golden Gate Drive, and Regional Street. There are no bicycle lanes in the project vicinity.

The Stoneridge Corporate Plaza office complex is located to the east, an office complex to the west, and the Stoneridge Mall is located to the south. All of these developments provide parking near the project site. Based on information provided by the City of Pleasanton Planning Staff, about 93 percent of the 565,000 square feet of office space in the Stoneridge Corporate Plaza is currently occupied. This is a multi-tenant office, complex and is. COnsidered to be full when it is 95 percent occupied. Therefore, the parking conditions observed in April are close to representing conditions when the complex is fully utilized. The office complex has approximately 90 spaces directly adjacent to the proposed site. These spaces were about 50 percent occupied during the observation period. Along 1-580, the complex has 300 additional parking spaces, of which 50 percent or less were occupied. Another parking area located along the south and east side of the westernmost office building has approximately 520 spaces and was S(f~rcent OCCllpi~d.The~ffice compie~to the westoFthe project site has approximately 250 spaces, of which 80 percent were occupied. This building is currently full. The proposed project would share the westernmost Stoneridge Corporate Plaza driveway on Stoneridge Mall Road, along which the previously identified 90 parking spaces are located. This driveway is located opposite a main driveway for the Nordstrom building in the Stoneridge Mall and bisects a parking area with approximately 1,600 spaces. This mall parking area was approximately 50 to 65 percent occupied. The 65-percent occupancy occurred during the noon hour. The majority of unoccupied spaces were adjacent to Stoneridge Mall Road, although there were a number of vehicles parked just to the west of the driveway. The only sidewalk in the vicinity of the proposed project is located just to the south of the site on the east side of Stoneridge Mall Road. Safeway will install sidewalks along the north side of Stoneridge Mall Road, east past the project site. There are no other pedestrian facilities, including sidewalks and marked crosswalks. In addition, there are no bicycle lanes in the project vicinity.

Exhibit 4.5-5 illustrates the existing a.m. and p.m. peak hour turning movement volumes. The intersections of San Ramon RoadfInterstate 580 Westbound Ramps and St. Patrick WayjRegional Street do not currently exist. San Ramon RoadjInterstate 580 Westbound Ramps are plaimed to be reconfigured as part of the modification of the existing four-quadrant cloverleaf into a partial cloverleaf. The intersection of St. Patrick WayjRegional Street is not analyzed in this study, but is represented on the figures to illustrate the concept of St. Patrick Way extending between Golden Gate Drive and Regional Street. The intersection of St. Patrick Way/Golden Gate Drive does exist, but is not analyzed under existing conditions since traffic volumes are negligible. The intersection of St. Patrick Way/Amador Plaza RoadjInterstate 680 Southbound Ramps currently exists as a T-intersection with only St. Patrick Way and Amador Plaza Road existing. The fourth leg will be the 1-680 southbound ramps. This intersection also is not analyzed under existing conditions since it is partially built and traffic volumes are negligible. All of the intersections analyzed under existing conditions are currently signalized intersections. All of the study intersections analyzed under existing conditions are operating acceptably at LOS A or B during the a.m. peak hour. During the p.m. peak hour, all of the intersections operate acceptably at LOS A or B, except Dublin BoulevardfDougherty Road, which operates acceptably at LOS D (v/c = 0.86). Table 4.5-1 presents a summary of existing peak hour levels of service at the study intersections. Level of service worksheets are provided in Appendix B. EXISTING PLEASANTON TRAFFIC CONDITIONS Existing conditions are based on the City's annual traffic counts for the year 2000 (City of Pleasanton, February 2000). All 12 study intersections are currently signalized. Currently, all 12 study intersections operate at acceptable levels of service. The intersection of Foothill Road/Canyon Way is operating at LOS D just above the minimum acceptable standard. Table 4.5-2 presents a summary of existing peak hour levels of service.

Therefore, the project is considered to significantly impact an intersection if the addition of project traffic during the year selected for analysis: );41 ,~ . .. . causes an intersection operating acceptably at LOS D or better to deteriorate to LOS E or LOS F, ',;'/ Jm . . causes an intersection operating unacceptably at LOS E to deteriorate to LOS F, 4'1 Ai . increases the volume-to-capacity ratio at a signalized intersection operating unacceptably at LOS E or LOS F by 0.02 or more, . i1! .. . increases the total entering volumes at an unsigna1ized intersection operating unacceptably at LOS E or LOS F by two percent or more, II · results in parking demand in excess of the available supply within the project site, triggers the Caltrans Peak Hour Volume Signal Warrant at an unSignalized intersection, or @ . IIlIii · provides unsafe or inefficient vehicular, pedestrian, and bicycles access and on-site circulation. .. Intersections operating at LOS E or F are characterized by congestion and excessive delay. The significance criteria for intersections already operating unacceptably is consistent with the criteria established in the most recent environmental studies for BART projects, which include the BART San Francisco Airport Extension Project. ..I iii DUBLIN TRAFFIC ANALYSIS IlIIl ANALYSIS METHODOLOGY The methodology used is based on the process approved by the City of Dublin for analyzing traffic impacts of proposed development.

The hotel is anticipated to generate approximately 1,975 daily trips, 134 trips during the a.m. peak hour and 146 trips during the p.m. peak hour. The trip generation for the hotel is conservative in that it is not likely there would be a significant reduction in vehicle trips for this use during the a.m. and p.m. peak hours even though it is near the BART Station. It is anticipated that air travelers using the hotel would come from the three Bay Area airports (San Francisco, Oakland, and San Jose) via private auto. Also, the hotel would not be located within walking distance of large employment centers. BART Station ....... ~ ; t !lO'o The trip generation for the West Dublin/Pleasanton BART Station was based on ridership projections from the March 2000 update of the BART Ridership Forecasting Model for Year 2010 and information based on current station activity of the East DublinjPleasanton BART Station (BART, 2000 and Herhold, 2000). r In the Year 2010, approximately 5,736 passengers per day are estimated to access the West DublinjPleasanton BART Station. Based on current activity of the East DublinjPleasanton BART Station, about 792 of these passengers (610 entriesf182 exits) are expected to ride BART during the im. peak hour and 723 passengers (231 entriesf492 exits) during the p.m. peak hour. [ T. he. types of. passengers were divided into. two categories.: home-bas, ed p. as,.s. engers an. d work-based pass~I1gers.The horn~-baS~d passengers are those that: ori~at:efron; their homes in the area and use the West DublinjPleasanton BART Station. These passengers enter the station in the morning and exit in the evening, contributing to the peak commute direction. The work-based passengers are those that take BART from a different station to the West DublinjPleasanton BART Station and are bound for places of work in the area. These passengers exit the station in the morning and enter in the evening, contributing to the reverse commute direction. It is possible that home-based and~ work-based passengers use BART in the opposite direction than what is described above (i.e., home-based trips made by night-shift workers may be exiting in the morning). However, these trips are negligible and are not considered in the trip generation calculations. ~. .;,., :.;. .. r' Mode split information was provided by BART based on existing characteristics on the BART system. Adjustments to these percentages were made to balance walk trips between BART and the residential use. Table 4.5-4 summarizes the resulting mode split percentages. .......

However a.m. exits and p.m. entries are assumed to be work-based trips and are based on the mode split and two passengers per shuttle. 3 Home-based car drop-offs in the morning (a.m. entries) and car pick-ups in the evening (p.m. exit) are added to the a.m. exits and p.m. entries. Work-based car pick-ups in the morning plus shuttle estimates (a.m. exits) and car drop-offs in the evening plus shuttle estimates (p.m. entries) are added to the a.m. entries and p.m. exits, respectively. Source: TJI<M 2000 Based on the mode-split percentages, vehicle trips were calculated. For the bus/transit trips, it is assumed that eight buses arrive at the BART Station in Dublin every 20 minutes. Therefore, 24 inbound and 24 outbound bus trips would occur at the BART Station in Dublin. These trips are not dependent on the ridership estimates derived from the mode split, and buses serve both home-based and work-based passengers. Home-based vehicle trips, a.m. entries and p.m. exits, were calculated directly based on the mode split, assuming 1.1 passengers per vehicle (i.e., a.m. entries: 75% x 610 passengers = 458 passengers at 1.1 passengers per vehicle = 416 vehicle trips). However, for the work-based trips it is assumed that BART passengers use (work provided) shuttles at a rate of two passengers per shuttle (i.e. a.m. exits: 15% x 210 passengers = 32 passengers at two per shuttle = 16 shuttles). Vehicle trips were also estimated based on drop-off and pick-up information for home-based and work-based passengers. Vehicles dropping off passengers in the morning and picking up passengers in the evening (home-based trips) are added to the a.m. exiting vehicle trips and p.m. entering vehicle trips. Similarly, vehicles picking up passengers in the morning and dropping off in the evening (work-based) are also counted as a.m. entering vehicle trips and p.m. exiting vehicle trips.

Table 4.5-5 provides the total estimated trip generation for the proposed project on the Dublin parcel including the residential, hotel, and BART Station uses. Approximately 63 percent of the total BART trips are anticipated to come from San Ramon, Danville, Dublin, or other locations from the north and, therefore, are anticipated to access the station in Dublin.

I ~ 10 , ast/ Approximately~5 percent of the trips are anticipated to come from Pleasanton and other locations from the south on 1-680, and would also access BART in Pleasanton, for a total 37 percent. These estimates are based on the existing trip distribution percentages of the East DublinfPleasanton BART Station and knowledge of the study area. It is assumed that vehicles originating or destining , east of the East DublinfPleasanton BART Station (Livermore and Tracy areas) would continue to use the East DublinfPleasanton BART Station and would not use the West DublinjPleasanton BART Station. The trip distribution percentages were adjusted to reflect this assumption. The trip distribution of the home-based trips for the West Dub1injPleasanton BART Station is shown on Exhibit 4.5-8. It is estimated that home-based trips would be either vehicle trips new to the study area, existing trips within the study area diverted from the East DublinjPleasanton BART Station, or trips within the study area diverted from the freeway. The new home-based trips would likely be generated by reSidences outside of the Cities of Dublin and Pleasanton that currently do not use any of the study intersections. These trips would include existing commute trips made from San Ramon and Danville using the local freeways only (1-680 and 1-580) and not any study roadways. To estimate the percentage of home-based trips that would be new trips, local residential growth rates were compared to the BART ridership growth rates. The BART growth rates were estimated to be roughly 10 to 20 percent greater than residential growth rates for similar time frames. As a result, it is assumed that 15 percent of the home-based trips are new trips, and are added as new trips to the study intersections. The remaining 85 percent of the home-based trips are assumed to be either existing commute trips diverted from the East DublinjPleasanton BART Station or commute trips diverted from 1-580. The number of home-based trips resulting from a diversion from the East DublinjPleasanton BART Station were estimated using existing vehicle count information from the station and an imaginary screenline through the City of Dublin at DOllgherty Road. None of the existing trips accessing the East DublinjPleasanton BART Station from the east on 1-580 are assumed to divert. Using the screenline developed based on the city street network and geographical. distribution of resIdences, roughly 60 ..;,,'1 ',:~ percent of the trips currently accessing the East DublinjPleasanton BART Station from the west are estimated to divert to the proposed West DublinjPleasanton BART Station. The remaining number of home-based trips to the proposed station are expected to be from commuters already using 1-580. This East DublinjPleasanton BART Station diversion and freeway diversion results in a reduction of trips at some of the intersections and an addition of trips to others.

These estimated daily volumes were then added to the actual existing daily volumes. The resulting ADT volumes for all study scenarios are shown on Exhibit 4.5-11. An appropriate level of service methodology for two-lane (one-lane in each direction) segments can be found in the Transportation Research Board's 1994 Highway Capacity ManUal (HCM). The HCM methodology for two-lane roadways yields a maximum ADT of 15,600 vehicles per day (vpd) to maintain a Level of Service D. This value is used in this analysis as an upper threshold for average daily traffic for two-lane roadway segments. ADT volumes of 30,000 vpd and 50,000 vpd are the acceptable upper thresholds for four-lane and six-lane arterials, respectively. These thresholds were established by the City of Dublin Circulation Element of the General Plan. (City of Dublin, 1997). Results Based on the 15,600 vpd, 30,000 vpd, and 50,000 vpd thresholds described above, the following improvements would be required: Under the Existing plus Approved scenario, one roadway segment is expected to exceed 30,000 vehicles per day. Dublin Boulevard between Dougherty Road and Village Parkway is expected to carry 32,500 vpd, and would need to be widened to six lanes. Dublin Boulevard is planned to be widened to six lanes (three in each direction) between Village Parkway and Dougherty Road by the City of Dublin within the next five years. Under the Existing plus Approved Projects plus Project scenario, no additional roadway segments are expected to exceed the City thresholds. ST. PATRICK WAY EXTENSION The need to construct St. Patrick Way between Golden Gate Drive and Regional Street with the construction of the proposed project was evaluated. This extension would serve the BART complex and offer another access option via Dublin Boulevard, Regional Street, and St. Patrick Way. The extension would be needed if it improves service levels at ~urrounding intersections that operate unacceptably at LOS E or F. - Based on the levels of service analysis, the intersection of Dublin Boulevard/Golden Gate Drive is expected to operate at LOS A during the a.m. and p.m. peak hours with the addition of the project.

The hotel and residential components would share a driveway on Golden Gate Drive located between the two uses. The St. Patrick Way extension would be needed if this main access point were illsufficient to handle traffic from both uses. The St. Patrick Way extension would be adjacent to the residential use, and if built, would provide a second access for the residential units. The level of service at the hotel/residential driveway and its proximity to the intersection of St. Patrick Way/Golden Gate Drive are acceptable. Again, there would be no benefit to extending St. Patrick Way between Golden Gate Drive and Regional Street due to the proposed project. DUBLIN SITE ACCESS AND CIRCULATION Dublin Parcel Access and Circulation. The proposed project design provides adequate site access and circulation on the Dublin parcel to accommodate the proposed uses. Therefore, no significant access or circulation impacts would be anticipated. Impact 4.5-2 The primary access to the hotel and the residential uses would be via a shared driveway on the west side of Golden Gate Drive. This driveway is located about 400 feet south of the St. Patrick Way alignment and about 175 feet north of the south end of the cul de sac at the foot of Golden Gate Drive. The hotel has surface parking located to the west and south sides of the hotel buildings. A guest drop-off area is located at the front of the hotel. No significant impacts associated with hotel access or circulation would be anticipated. However, left-turning vehicles exiting the driveway are expected to experience some delay during the peak hours. Golden Gate Drive will be restriped to include a two-way left turn lane. This improvement will allow vehicles to cross over one lane of traffic and merge into the through lane. In addition, if a traffic signal is installed in the future at the intersection of St. Patrick Way/Golden Gate Drive, it will provide gaps in traffic to allow left turns out of the driveway. The residential parking consists of surface parking on the west side of the residential building and garage parking below the building. Access to the garage is via two entrances from the surface lot and one entrance directly onto Golden Gate Drive. The garage access onto Golden Gate Drive is located approximately 200 feet south of the St. Patrick Way alignment, opposite an existing driveway on the east side of Golden Gate Drive. No significant impacts associated with access or circulation at the residential building would be anticipated. Similar to the operations at the hotel driveway, left-turning vehicles exiting the driveway are expected to experience some delay during the peak hours.

The BART parking area consists of713 parking spaces. Access to the garage would be from a driveway onto the foot of the Golden Gate Drive cul de sac. In addition, the ground-level bus loading area consists of eight bus bays andadditionJ surface parkirig thatis expected to be reserved for drop-offs and pick-ups of BART patrons. The bus circulation area requires buses to V-turn on the ground floor ()f the structure. The design accommodates a 50-foot milling radius. This would be adequate to accommodate the Wheels bus system vehicles. The BART parking area is compact, occupying an area of 2.464 acres. The access for all BART-related parking occurs through a single driveway. All BART patrons arriving in private autos to be parked, in drop-off vehicles or in buses would access the parking area from this driveway. Although there is the potential that a blockage of this driveway could disrupt on-site traffic flows, this would generally be considered an unusual event. Therefore, no significant impacts associated with access or circulation at the BART parking area would be anticipated. PLEASANTON TRAFFIC ANALYSIS ANALYSIS METHODOLOGY The methodology used is based on the process approved by the City of Pleasanton for analyzing traffic impacts of proposed development. This traffic analysis evaluates the impaCts generated by the proposed project on 12 intersections in the study area.

In addition to the evaluation of existing land use and roadway conditions, traffic conditions were analyzed for four future land use and roadway network scenarios with and without the planned but ~~ed 1-680 inteJ.:cl1ang;e at West Las posit:as Boulevard. The I-680fWest Las Positas interchanges is identified for construction by the City of Pleasant on General Plan; however, the West Las Positas Citizens' Committee is currently in the process of determining the impacts of removing the interchange from the General Plan (City of Pleasant on, August 1996). The snidy scenarios are listed below. r r r r- t ~ . r- I t The f<;>llovving scenarios demonstrate the project's effects in the near-term: . Existing Conditions - This scenario consists of existing traffic volumes and roadway conditions obtained from the City of Pleasanton's annual traffic counts for the year 2000 (City of Pleasanton, February 2000). . Existing plus Approved: With and WIthout West Las Positas Interchange Conditions - This scenario assumes existing land use conditions plus future traffic from all approved but unbuilt Otl.ll1occupied development in the City of Pleasant on. Hacienda Business Park is treated as an approved project according to the most current development agreement between the City of Pleasanton and Hacienda Business Park. Existing plus Approved Projects plus Project: With and Without West Las Positas Interchange Conditions -This scenario is identical to the Existing plus Approved scenario but with traffic added from the development of the proposed project, including the BART Station and office building. . The City of Pleasant on evaluates operating conditions at signalized intersections using a methodology known as the lev method. Peak hour intersection conditions are reported as volume to capacity (vjc) ratios along with their corresponding level of service ratings. Level of service ratings are qualitative descriptions of intersection operations and are reported using an A through F letter rating system to describe travel delay and congestion. LOS A indicates free-flow conditions with little or no delay and LOS F indicates jammed conditions with excessive delays and long back-ups. Appendix B contains a detailed description of the level of service methodology.

Approved projects consist of developments that have fmal development plan approval from the City, but are either unbuilt, under construction, unoccupied or partially occupied. Approved projects are used to forecast near-term traffic conditions. The City ofPleasanton maintains a database of approved projects and typically updates it on an annual basis to include current approvals (and to delete approved projects that have been constructed and fully occupied). "'", .~..~ .. ~7. d.: .. ~ .. .. Subsequent to adoption of the 1998 Pleasanton Traffic Model it was discovered that the expansion of the Safeway Corporate Headquarter, an approved project located at the northwest comer of Stoneridge Mall Road and Canyon Way, was not included in the City's approved land use database (City of Pleasanton, June 1999). Therefore, the expansion of the Safeway Corporate Headquarters was added to the approved project list. It should be noted that approved projects in the mall area also includes an expansion of Stoneridge Mall. Appendix B contains the list of approved developments and corresponding occupancies considered under this scenario. .. .. ;;. ,':;- . All approved projects analyzed in this report are assumed to be built and fully occupied in the future traffic scenarios except for a five percent vacancy rate assumed for multi-tenant office space. The traffic generated by the already occupied portions of each building is accounted for in the turning movement counts conducted in 1998. The future traffic from unoccupied portions of approved projects was analyzed by a trip generation, distribution and assignment process to determine future peak hour flows at the study intersections. .",~ .~ '-?"1" ;{; -: .'$. .: ;;.' The City of Pleasant on Traffic Model was utilized to obtain vehicular trip generation, distribution, and assignment assumptions for this future scenario as well as all other future scenarios (City of Pleas anton, June 1999). Detailed trip generation assumptions for all future scenarios are contained in Appendix B. Exhibit 4.5-13 identifies the existing turning movement volumes. Exhibit 4.5-14 illustrates Existing plus Approved traffic volumes without the West Las Positas interchange. .. >'5 - Planned Intersection Improvements ~' IIi addition to the previously described regional roadway improvements, the future study scenarios assume that specific intersection improvements planned by the City of Pleasant on are completed. These improvements are either part of an approved development agreement, fully funded, or partially funded through a combination of developer contributions, development impact fees and City funding sources. ~ .. lIII EDAW T ransportotion/Circulation 45-40 Son Francisco Boy Area Rapid Transit District West DublinlPleosanton BART Station and Transit Village ;;l i4 - & r' ~ ,... ....... c '., <? 0 t...... ~, :8e. ~~ t 2m t~'.. ,.5~ CD ~ ' ."; . - '...1 m ~ ~d ~ ~~ r~ ! ;;;;;- ~o 0>0 c~ ....co :8 Do ~+ ; ~ j _ ',",,-,' !' ~'.....'.'..:....._~; <t~v) 69V~ g , co .......

The median on eastbound Dublin Canyon Road will be narrowed and existing lanes restriped to provide two exclusive left-turn lanes, a shared left-turn and through lane, and an exclusive right-turn lane. Developers in the Stoneridge Mall area are obligated to inst~. these improvements. These improvements are estimated to occur within the next 5 years. . 1-680 Southbound RampjStoneridge Drive (No. 346): The southbound 1-680 off-ramp will be restriped to convert two right-turn lanes and two left-turn lanes into one right-turn lane and three left-turn lanes. This is a low-cost improvement and is expected to be completed by the City of Pleasant on using available developer fees. All other approaches will remain unchanged. These planned improvements are included in the intersection level of service analyses for the future study scenarios. Results of Level of Service Analysis The forecasted traffic volum~ illustrated in E~~it .4.5-14 we~e analyzed t? detennine intersection levels of service under the Existitlg plus Approved Projects scenario with and without the West Las Positas interchange.

Based on a review of trip generation analyses recently performed for other office developments in the City of Pleasanton, it was determined that a 15% transit reduction would be applied resulting in a conservatively high trip generation estimate. With the transit reduction, the estimated trip generation of the proposed office is 192 vehicle trips during the a.m. peak hour and 192 trips during the p.m. peak hour. BART Station The Dublin Traffic Analysis section of this report describes calculation of the vehicle trip generation related to the proposed West DublinjPleasanton BART Station. Table 4.5-4 above summarizes the total trip generation estimated for the West DublinjPleasanton BART Station. Approximately 37% of the total BART trips are anticipated to access the BART Station from Pleasanton using local roads, from the south on 1-680, and from the north on San Ramon Road, as described below. The remaining 63 percent would access the Station from the Dublin side. As shown in the table, on the Pleasanton side, the BART Station is estimated to generate about 1,300 daily trips, including 239 a.m. peak hour trips and 202 p.m. peak hour trips. For the bus/transit trips, it is assumed that one bus arrives at the BART Station in Pleasanton every 20 minutes. Therefore, 3 inbound and 3 outband bus trips would occur at the BART Station in Pleasanton. Table 4.5-8 summarizes the estimated trip generation for the Pleasanton parcel.

Traffic Model included assumptions for the traffic produced by the previously contemplated West DublinjPleasanton BART Station (City of Pleasant on, June 1999). The model assumed 220 BART-related vehicle trips during the a.m. peak hour and 290 during the p.m. peak hour. These vehicle trip generation assumptions were a preliminary estimate based on driveway counts on the Pleasanton side of the East DublinjPleasanton BART Station. This EIR replaces the previous model assumptions with trip generation estimates based on new BART ridership projections for the currently proposed station as described above. Trip Distribution and Assignment The Dublin. Traffic Analysis portion. of this section describes Clevelopment of .the overall trip distribution assumptions for the proposed West DublinjPleasanton BART Station, which are also illustrated in Exhibit 4.5-ifltis estiffiatedthat:vehicles coming from withinPleasanton using local roads, from the south on 1-680, and a portion of these coming from the north on San Ramon Road, about 37 percent of all vehicles, would access the proposed BART Station ill Pleasanton. The trip distribution of the BART home-based trips for Pleasanton is shown on Exhibit 4.5-15. As in the Dublin Traffic Analysis section, it is estimated that home-based trips would be either vehicle trips new to the study area, existing trips within the study area diverted from the East Dublin Station, or trips within the study area diverted from the freeway. The new home-based tI"if~ would likely be generated by residences outsi~:~f the cities of Dublin and Pleasanton that currently do not use any of the study intersections. These trips would include existing commute trips made from using the local freeways only (1-680 and 1-580) and not any smdy roadways. As previously described, it is assumed that 15 percent of the home-based trips are new trips and are added to the study intersections. The remaining 85 percent of the home-based trips are assumed to be either existing commute trips diverted from the East Pleasanton BART Station or commute trips diverted from 1-580. The number of home-based trips resulting from a diversion from the East bublin/Pleasanton BART Station were estin1~~:d llSing exis~g vel1icle coun~ informati?~from the East DublinjPleasanton BART Station andafi imaginary screenline through the City o(Pleasanton at Hopyard Road.

Using the screenline developed based on the city street network and geographical distribution of residences, roughly 45 percent of the trIps currently accessing the East DublinjPleasanton BART Station from the west are estimated to divert to the proposed West DublinjPleasanton BART Station. /.:.., L Son Francisco Boy Areo Rapid Transit District West DublinlPleosanton BART Station and Transit Village 4.5-47 EDAW T ransportationlCirculation HACIENDA DR.
