The City Council desired to mold this core area into a cohesive historic district to better highlight Dublin's historic and archeological resources, to protect and preserve these resources, and to further enhance the area with development that is compatible with the historic buildings and remnants in the area. In addition to the specific plan study, the City has also been examining various ways to eliminate the 5.3-acre parkland deficit that was identified in the Park and Recreation Master Plan 2004 Update. The City has considered several potential park sites, one of which is the Dublin Square Shopping Center site adjacent to the City's Heritage Center and in the project area. The two parallel planning processes (the Historic Area Specific Plan study and Parkland Deficit Elimination assessment) have moved forward concurrently, and it is the intention that this Initial Study be the environmental document which covers the entirety of these activities and the actions described as follows. Project Description In an effort to further the City's efforts stated above, the City of Dublin is proposing the following actions, which collectively describe the project for the purposes of the California Environmental Quality Act (CEQA): 1. Adoption of an amendment to the City of Dublin General Plan to change the land use designation (and any related map or text amendments) on the parcels listed as follows (See Exhibit 3 for reference): Site Common Name Address APN Existing GP land Proposed GP land use use designation designation Dublin Square 11759 Dublin Blvd. 941-1560-007 -01 Retail/Office Parks/Public Recreation Shopping Ctr. Green Store 11873 Dublin Blvd. 941-1550-004 Retail/Office Parks/Public Recreation Hawthorne Lane/ N/a 941-1560-005 Retai I/Office Parks/Public Recreation Pioneer Cemetery Pioneer Cemetery N/a 941-1560-006 Retail/Office Parks/Public Recreation DHPA parcel N/a 941-1560-003-03 Retail/Office Parks/Public Recreation 2. Adoption of the Draft Dublin Village Historic Area Specific Plan. The Specific Plan contains greater detail on the City's goals for the historic area, an analysis of the existing conditions in the area, design guidelines for future development in the area, recommendations for streetscape improvements, and designation of the specific plan land use categories compatible with the General Plan. Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 3 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 3. Rezoning of sites in the Project area to reflect General Plan Amendment. Rezoning to change the zoning designation for the following sites to become compatible with the Park/Public Recreation Specific Plan and General Plan land use designations: Site Common Name Address APN Existing Zoning Proposed Zoning Dublin Square 11759 Dublin Blvd. 941-1560-007-01 C-1 (Retail Planned Development Shopping Ctr. Commercial) (Dublin Village Historic Area Specific Plan) Green Store 11873 Dublin Blvd. 941-1550-004 Planned Planned Development Development (Dublin Village Historic Area Specific Plan) 4. Adoption of an amendment to the Parks and Recreation Master Plan 2004 Update to reflect the elimination of the park deficit after the General Plan land use change and to note the future Dublin Historic Park location. 5. Adoption of the Dublin Historic Park Draft Master Plan. The Dublin Historic Park Draft Master Plan contains the Conceptual Design for the park including both interim and ultimate improvements. (See Exhibits 6 and 7 for a description of the interim and ultimate improvements). Interim improvements include streetscape improvements along Dublin Boulevard and Donlon Way, acquisition and demolition of the existing shopping center at 11759 Dublin Boulevard, construction of the park parking lot, and installation turf as well as temporary rotor irrigation. Ultimate improvements include full construction of all park and cemetery facilities as shown in Exhibit 7. 6. Rescission of the Dublin Village Design Guidelines. The Design Guidelines were adopted in January 2005 with the intention that they would serve until the Dublin Village Historic Area Specific Plan was finalized and adopted, which would contain the design guidelines inside the specific plan document. Once the Specific Plan is in place, there is no need for the stand-alone design guidelines document. 7. Amendment to Chapter 8.62 of the Dublin Zoning Ordinance (Historic Overlay Zoning District Site Development Review). This section of the Zoning Ordinance will be amended to remove reference to development in the Project area needing to be in compliance with the Dublin Village Design Guidelines and instead note that development in the Project area will need to be in compliance with the Dublin Village Historic Area Specific Plan. 8. Acquisition of those sites in the specific plan area designated Parks/Public Recreation that will be needed for the implementation of the Dublin Historic Park Draft Master Plan. 9. Demolition of the existing structures and pavement on the Dublin Square Shopping Center site (APN 941- 1560-007 -01) to prepare for the implementation of the Daft Dublin Historic Park Draft Master Plan. 10. Construction of the Dublin Historic Park Draft Master Plan interim improvements. 11. Construction of the Dublin Historic Park Draft Master Plan ultimate improvements.

The precise location of Dublin is identified in Exhibit 1. The Dublin Village Historic Area consists of approximately 38 acres of land located northwest of San Ramon Road and Interstate 580. The Historic Area includes commercial, residential, public, and business park/industrial properties near the intersection of Donlon Way and Dublin Boulevard, as shown in Exhibit 2. From this point forward, the Dublin Village Historic Area will be referred to as the "Project Area." Specifically, the project area is made up of the following parcels (as shown in Exhibit 3): Parcel Number Business/Use Address 941-0040-006-1 0 Apartment complex 7100 San Ramon Road 941-0040-006-16 Retail store 11865 Dublin Boulevard 941-0113-003-01 Daycare Center 11760 Dublin Boulevard 941-0113-154 Office Building 11824 Dublin Boulevard 941-1550-001-02 Telecommunications switching station 11991 Dublin Boulevard 941-1550-001-12 Gas station 11989 Dublin Boulevard 941-1550-003-02 Restaurant 11891 Dublin Boulevard 941-1550-004 Church 11873 Dublin Boulevard 941-1550-005-02 Office Park 11887 Dublin Boulevard 941-1560-001-01 City Of Dublin Heritage Center: St Raymond's Church 6506 Donlon Way City Of Dublin Heritage Center: Murray Schoolhouse and 941-1560-001-02 Pioneer Cemetery 6600 Donlon Way 941-1560-002-02 Single Family Home and Dog Kennel 6572 Donlon Way Vacant property owned by Dublin Historical Preservation 941-1560-003-03 Association No address 941-1560-005 City of Dublin Heritage Center: Pioneer Cemetery No address 941-1560-006 City Of Dublin Heritage Center: Pioneer Cemetery No address 941-1560-007-01 Retail Shopping Center 11759 Dublin Boulevard 941-1560-003-04 Hexcel Corporation Business Park No address 941-1560-009-01 Hexcel Corporation Business Park 11711 Dublin Boulevard 941-1560-010-01 Medical building No address 941-1550-002-02 Vacant property owned by Caltrans No address 941-1550-001-10 Vacant property owned by Caltrans No address Physical Setting, Uses, and Structures The general character of the project area is urbanized postwar suburban, and although today dominated by late twentieth century commercial, retail and residential uses, the project area also contains several historically significant buildings, structures, sites, objects and landscape features dating from the latter half of the nineteenth century and the early part of the twentieth century. Most of the buildings in the project area are commercial and residential structures of one and two stories, built primarily in the 1960's, 70's, and 80's, but there are several Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 5 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 historic structures as well. Exhibit 4 shows the general location and common names of the buildings and sites in the area. Identified historic resources are concentrated along Donlon Way, centering on the City-owned Dublin Heritage Center site, which includes the Murray Schoolhouse, Dublin Pioneer Cemetery and St. Raymond's Church. Another identified historic resource is Green's Store, a privately owned former general store and tavern located on the southeast corner of Dublin Boulevard and Donlon Way. Previously unidentified potential historic resources are scattered throughout the survey area. These include: "Ponderosa," a circa-1929 bungalow at 6570 Donlon Way; the Bonde House, a circa-1923 bungalow at 11760 Dublin Boulevard; Alamilla Springs and remnants of a walnut grove at 7100 San Ramon Road; historic walnut and pepper trees on the Heritage Park Office Center property at 11887 Dublin Boulevard; as well as potential archaeological sites in the vicinity of Dublin Creek and the Heritage Park Office Center. The other structures in the area are a 176 unit apartment complex on the north side of Dublin Boulevard (The Springs Apartments), an approximately 41 ,000 square foot commercial center on the southwest corner of Dublin Boulevard and Donlon Way (Dublin Square Shopping Center), and an approximately 106,000 square foot office complex on the southeast corner of Dublin Boulevard and Donlon Way (Heritage Park Office Center). The Hexcel Corporation owns an approximately 56,000 square foot light industrial office/manufacturing complex on the south side of Dublin Boulevard, between the street and Interstate 580. Other smaller-scale commercial buildings are also prevalent in the area and include a gas station, restaurant, bank, and other retail and office establishments. In addition to the built environment, the project area also contains a valuable natural resource. Dublin Creek runs through the portion of the project area adjacent to the Dublin Heritage Center and the vacant property proposed for the cemetery expansion. Although partially channeled today, this section of Dublin Creek retains its natural bed as well as some of its riparian woodland corridor.

ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "potentially significant impact" as indicated by the checklist on the following pages. Aesthetics Agricultural Resources Air Quality Biological Resources Cultural Resources Geology/Soils Hazards and Hazardous Hydrology/Water Quality Land Use/ Planning Materials Mineral Resources Noise Population/Housing Public Services Recreation Transportation/ Circulation Utilities/Service Systems Mandatory Findings of Significance DETERMINATION: On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. X I find that although the proposed project could have a significant effect on the environrrent, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

The scope of review includes only potential impacts resulting from development of the facilities described in the above documents. Any potential site-specific environmental impacts not anticipated during this environmental review will need to be addressed as part of an application submittal consistent with CEQA requirements. Additionally, any development in the project area that is outside the scope of this document may need further analysis if it can be determined that potential environmental impacts exist. The method of environmental analysis includes a review to determine whether the impact related to the City's evaluation criteria would be: potentially significant; less than significant unless mitigation is incorporated; less than significant; or no impact. The analysis includes a summary of the affected environment and a review of the threshold for determining significance. The evaluation of potential impacts applies the threshold, determines significance and, if necessary, includes recommended mitigation measures. Sources used to determine potential environmental impacts: 1. Determination based on Staff review of the project. 2. Determination based on field visit and site inspection. 3. Determination based on communication with appropriate City of Dublin departments and utility service providers 4. Determination based on the City of Dublin General Plan (1985, updated to 2002), 5. Determination based on the City of Dublin Zoning Ordinance. 6. Determination based on the Archeological Assessment Report for the Donlon Way Area Specific Plan (prepared by William Self Associates, Inc.) August 2003. 7.

Determination based on the Phase I Environmental Site Assessment for 11759 Dublin Boulevard (prepared by Treadwell & Rollo Environmental and Geotechnical Consultants for the benefit of Meyers Nave Riback Silver and Wilson) January 2005 Notes: 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact"answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2) All answers must take account of the whole action involved, including of-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, Less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Negative Declaration: Less than significant with mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" 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 (mitigation measures from Section XVII, "Earler Analyses," may be cross- referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are "Less than significant with mitigati01 Measures Incorporated," describe the mitigation measures that were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats; howeVEr, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance On the following page, the source of determination is listed in parenthesis. See listing of sources used to determine each potential impact at the end of the checklist. Copies of the documents referenced in this document are available for public review at the City of Dublin Community Development Deparlment, 100 Civic Plaza, Dublin, CA 94568. Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning Page 17 of 42 May 25, 2006 Aesthetics Would the project: (Sources: 1, 2, 11, 12) a) Have a substantial adverse impact on a scenic vista? b) Substantially damage scenic resources, including but not limited to trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light or glare that would adversely affect day or nighttime views in the area? Potentially Less than Less than No Impact Sig~ifiCqlflt significant Significant Impact with lr1Jpqct mitigation X X X X a-c) Have a significant impact on scenic vista, damage to scenic resource, degrade visual character of the site? No impact. The project area is not located in an area with any scenic corridor or scenic vista designation, so there will not be any impacts associated with implementation of the proposed project. The project will not degrade the existing visual character or quality of the site, but will instead improve and enhance the area with substantial public improvements, including the expansion of the City's Heritage Center and related streetscape improvements. d) Create a new source of substantial light or glare that would adversely affect day or nighttime views in the area? Less than siqnificant impact. The proposed project will involve the installation of new light fixtures in and around the Dublin Historic Park and related streetscape improvements, but it will not be in excess of the existing lighting on the current 4.2-acre shopping center site, which will be removed to make way for the future park. Therefore, the new lighting that is installed will be less than existing with the removal of the existing shopping center lighting when the center is demolished, and the new lighting will not adversely affect daytime or nighttime views. It is standard practice that a photometric study is provided with final construction drawings for any project prior to the issuance of an electrical permit. Adherence to this practice when construction documents are prepared for any project will ensure that the impact of new site lighting will be less-than-significant. This requirement will apply to all future development proposals in the project area. Agricultural Resources Would the project: (Sources: 1, 2, 5) a) Convert Prime Farmland, Unique Farmland or Farmland of Statewide Importance, as showing on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to a non-agricultural use? b) Conflict with existing zoning for agriculture use, or a Williamson Act contract? Potentially Less than Less than No Impact Significant significant Significant Impact with Impact mitigation X X Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning Page 18 of 42 May 25, 2006 Agricultural Resources Would the project: (Sources: 1, 2, 5) c) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of farmland to a non-agricultural use? Potentially Significant Impact Less than Significant Impact Less than significant with miti ation x No Impact. The project area does not contain any properties that are currently used for agriculture or farming, nor does the project area contain any properties with Williamson Act contracts or any farmland that would be converted to a non-agricultural use. There are six properties in the project area that have an Agricultural zoning designation, and of those six, five are contained in the proposed Historic Park expansion area (Assessor Parcel Numbers 941-1560-001-01,941-1560-001-02, 941-1560-003-03, 941-1560-005, and 941-1560-006) and three are the subject of General Plan land use changes from Retail/Office to Parks/Public Recreation (APNs 941-1560-003- 03, 941-1560-005, and 941-1560-006) to accommodate the implementation of the Dublin Historic Park Draft Master Plan. The park use proposed on the parcels (which fall into the community facility and cemetery use categories for purposes of zoning classification) are permitted in an Agricultural zoning district, so the proposed project does not conflict with the zoning and has no detrimental impact to agricultural resources. Air Quality (Where available, the significance criteria established by the applicable air quality management district may be relied on to make the following determinations). Would the project: (Sources: 1, 2, 3, 4, 12) a) Conflict with or obstruct implementation of the applicable air quality plan? b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? c) Result in a cumulatively considerabk3 net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions that exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant concentrations? e) Create objectionable odors affecting a substantial number of people? Potentially Significant Impact Less than significant with Less than Significant Impact x x x x x Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning Page 19 of42 May 25, 2006 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 gaps in the hills: the Hayward and Niles canyons. Local wind data show the frequent occurrence of low wind speed and calm conditions (the latter approximately 23 percent of the time). These local limitations on the capacity for horizontal dispersion of air pollutants combined with the regional characteristic of restricted vertical dispersion give the area a high potential for regional air quality problems. However, given the nature of the proposed project and the lack of land use intensification proposed, the overall impact to the region's air quality from this project will be less than significant. a-b) Would the project conflict or obstruct implementation of an air quality plan or violate any air quality standards? Less than siqnificant with mitiqation and Less than siqnificant impact. The proposed project would not conflict with the local Clean Air Plan adopted by the Bay Area Air Quality Management District, because the land use changes being proposed will actually result in a de-tensification of land uses (from Retail/Office to Parks/Public Recreation) and there are limited new facilities proposed in the area as part of the proposed Draft Dublin Historic Park Draft Master Plan. Air quality impacts result from two main sources: temporary impacts due to project construction and long-term impacts due to project operation. Generally, air quality impacts from project operation are based on vehicular emission from traffic. Project implementation will first involve the redesignation of five parcels from Retail/Office to Parks/Public Recreation, acquisition of those properties, and then the eventual demolition of approximately 40,000 square feet of commercial space to accommodate the development of the Historic Park. In terms of potential air quality impacts due to project operation, the proposed project will actually reduce the square footage of actual and potential development in the project area, which will reduce the number of vehicle trips generated by and to the project area, which will reduce the overall vehicle miles traveled and vehicle emissions. See Table 1 below for a summary of the proposed land use changes and how they will impact the overall development potential in the project area.

Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 20 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 Although the development potential of the site is higher than the amount of existing development currently in the project area, that potential exists now under current general plan and zoning designations, without the proposed project. The proposed project will actually decrease the development potential in the area and thereby reduce the potential amount of vehicular trips generated and the air quality impacts of those vehicle miles traveled. In addition to there being less development potential with the proposed project and therefore fewer vehicle trips generated in the project area, parks and recreational facilities are typically not large traffic generators, they are not typically peak-hour trip generators, and vehicle trips are spread throughout the day on weekdays as well as weekends. The proposed Dublin Historic Park Draft Master Plan includes the construction of an outdoor classroom as well as an outdoor stage, but even with those facilities the amount of traffic generated will be less than significant when compared to the existing and/or potential development under the existing designations. In terms of construction-related impacts, it is anticipated that the project would generate temporary increases in dust and particulate matter caused by minor site excavation and grading activities as buildings and facilities in the area are constructed. Construction vehicle equipment on unpaved surfaces generates dust as would wind blowing over exposed earth surfaces. However, City regulations require that a project-specific Stormwater Pollution Prevention Program (SWPPP) be developed when the construction drawings for the Historic Park are prepared, which will also address air quality issues. The SWPPP will contain measures relating to the containment of fugitive dust during grading and construction activities, mandating that construction equipment be kept in proper running order, mandating that the developer is responsible for watering or other dust-palliative measures to control dust as conditions warrant or as directed by the City Engineer, and mandating the avoidance of construction waste burning to reduce short-term air quality impacts to a less-than-significant level. Through the required SWPPP, the project shall implement dust control measures to reduce project dust deposition to acceptable levels. Dust control shall conform to the requirements of the SWPPP, which for the proposed Dublin Historic Park Draft Master Plan, will be developed by the Parks and Community Services Development Staff in cooperation with the City's Public Works Staff. Adherence to the following mitigation measure for all construction projects in the project area will ensure that the impacts of construction are less than significant: Mitiaation Measure 1: In accordance with City requlations, a proiect-specific Storm Water Pollution Prevention Proqram (SWPPP) shall be prepared in compliance with the City's NPDES permit. The SWPPP shall have the followinq minimum requirements: 1. Active construction areas will be watered daily and more frequently if necessary. 2. All trucks haulinq soil. sand or other loose materials shall be covered. 3. Water shall be applied daily, or apply non-toxic soil stabilizers on all unpaved access roads, parkinq areas, and exposed stockpiles at construction sites. 4. All access roads and parkinq areas at construction sites shall be swept daily with water sweepers. When any building in the Project area is proposed to be demolished, the Applicant or Contractor will be required to obtain a demolition permit from the City of Dublin. Part of the City's permit process is to require the Applicant or Contractor to provide notification of the demolition to the Bay Area Air Quality Management District (BAAQMD) and provide the BAAQMD with the results of a survey to determine if there is Asbestos Containing Material in the Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 21 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 structures to be demolished. If there is ACM in the structure(s), additional BAAQMD regulations apply. A job number is issued by the BAAQMD before a demolition permit can be issued by the City, which will ensure that all requirements of the BMQMD are followed and that the air quality impacts of the demolition will be less than significant. c) Would the project result in cumulatively considerable air pollutants? Less than siqnificant impact. The BMQMD has established thresholds for determining whether a given project has the potential for significant air quality impacts. If a project exceeds the thresholds, detailed air quality analyses are usually required. If the project does not exceed the thresholds, it is typically assumed to have a less than significant impact on air quality. BAAQMD does not usually recommend a detailed air quality analysis for projects generating less than 2,000 vehicle trips per day. Implementing the proposed project will not generate significant additional amounts of traffic, as described above. Vehicular emissions are estimated to be less than is currently permitted with the existing land use categories and the existing buildings, and no cumulatively considerable air pollutants are expected to be generated. . Overall, the air quality impacts associated with the proposed project would be below the standard of air quality significance as established by the Bay Area Air Quality Management District since no intensification of land use is proposed. d, e) Expose sensitive receptors to significant pollutant concentrations or create objectionable odors? Less than siqnificant impact. The Bay Area Air Quality Management District defines sensitive receptors as facilities where sensitive receptor population groups (children, the elderly, the acutely ill and the chronically ill) are likely to be located. These land uses include residences, schools, playgrounds, child-care centers, hospitals and medical clinics. This project would involve construction and development of a new park and recreational facility where people would gather for recreation, among other facilities which could be developed at a later date. The proposed Historic Park is not located in the vicinity of any significant generators of pollutants such as a factory or agricultural operation, but portions of the park are located adjacent to Interstate 580, which carries a significant amount of traffic and produces pollution and odors from vehicle emissions. However, the Historic Park Draft Master Plan includes the construction of a freeway sound wall incorporated into the project design, which will serve to shield the future park space from freeway noise, as well as air quality impacts. The portion of the Historic Park that will be closest to the freeway will be the cemetery expansion area. That is not an area that children, the elderly, the acutely ill and the chronically ill will typically gather for long periods of time, so limited impacts to sensitive receptors in the proposed project area are anticipated. Additionally, the cemetery expansion area is where the combination columbarium/soundwall is proposed to be constructed, which will serve to shield cemetery visitors from both the noise and air quality impacts of the adjacent freeway. Therefore, the overall impact of significant pollutant concentrations or objectionable odors is anticipated to be less than significant. Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 22 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 Biological Resources Would the project: (Sources: 1,2,3,4, 11, 12) a) Have a substantial adverse effect, either directly through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies or regulations, or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service? b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies or regulations or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service? c) Have a substantial adverse impact on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption or other means? d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local policies or ordinances protecting biological resources, such as tree protection ordinances? D Conflict with the provision of an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional or state habitat conservation plan? Potentially Less than Less than No Impact Significant significant Significant Impact with Impact mitigqtiqlfl X X X X X X a-b) Have a substantial adverse effect, either directly through habitat modifications, on any riparian habitat or species identified as a candidate, sensitive, or special status species in local or regional plans, policies or regulations, or by the California Department of Fish and Game or the U.S. Fish and Wildlife Service? Less than siqnificant with mitiqation. A majority of the project area is already urbanized and therefore the potential for impacts to flora or fauna are very limited. However, Dublin Creek runs through a portion of the project area, and there is a possibility that a candidate, sensitive, or special status species is in the creek that could be impacted by the construction of the proposed project. The California Natural Diversity Database (CNDDB) contains records for nine special-status animal species in the vicinity of the project area. California tiger salamander (Ambystoma californiense), California red-legged frog (Rana aurora draytonit), and Alameda whipsnake (Masticophis lateralis euryxanthus) are federally listed as threatened, while San Joaquin kit fox (Vulpes macrotis mutica) is federally listed as endangered. San Joaquin kit fox and Alameda whipsnake are also state-listed as threatened. The five remaining animal species are considered Species of Special Concern by the CDFG: burrowing owl (Athene cunicularia), California horned lark (Eremophila Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning Page 23 of 42 May 25, 2006 alpestris actia), tricolored blackbird (Agelaius tricolor), American badger (Taxidea taxus), and westem pond turtle (Emys marmorata). Two special-status plant species have been recorded in the greater Dublin area: Diablo helianthella (Helianthella castanea) and Congdon's tarplant (Centromadia parryi ssp. congdonil) (CNDDB 2006). It is unknown whether either of these species exist in the project area. However, due to the limited amount of construction proposed for the area immediately adjacent to Dublin Creek; primarily hardscape improvements, including a walkway and future cemetery plots, there would be a less-than- significant impact on biological resources with the mitigation measure below as no sensitive or special-status species or riparian features will be disturbed or destroyed in the project area. There are several guiding policies of the Parks and Recreation Master Plan Update that will ensure that impacts to biological resources resulting from project implementation are minimized. Guiding Policy 3.1 requires the creation of continuous visual open spaces, which are valuable for both recreational opportunities as well as habitat protection. Guiding Policy 3.2 encourages the protection of riparian corridors and oak land areas so that they will contribute to the ecological health of the open space system. Guiding Policy 3.6 emphasizes the protection of wildlife habitats and corridors and cooperation with the State Department of Fish and Game to define and preserve wildlife habitats. Adherence to these policies of the Parks and Recreation Master Plan and the other mitigation measure identified below will ensure that the park development portion of the project's potential impacts to Dublin's biological resources are less than significant. MitiQation Measure 2: A bioloqical survey shall be conducted by a qualified bioloqist prior to any disturbance within 150 feet of Dublin Creek (Le qradinq, construction of nearby pathways, construction of the creek foot bridqe) and on the undeveloped DHPA parcel to verify that no special species are located in the area proposed for park expansion. Requlatory permits shall be obtained as necessary from the Fish and Wildlife Service, Califomia Department of Fish and Game, Army Corps of Enqineers, or State Water Resources Control Board as necessary, and in coniunction with the recommendations of the bioloqical report. c) Have a substantial adverse impact on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption or other means? Less than siqnificant with mitiqation. There are minimal alterations proposed to Dublin Creek in the project area. The Dublin Historic Park Draft Master Plan shows plans for a footbridge to connect the existing Pioneer Cemetery with the cemetery expansion area on the south side of Dublin Creek. The Master Plan, which is a conceptual-level document at this point, envisions using a prefabricated steel structure that is 88 feet in length and 12 feet wide. The concrete footings will be designed to minimally impact the riparian area, but the specifics won't be known until the bridge engineering is done at the stage when a construction bid is prepared. At that time, the potential impacts of the footbridge footings can be more accurately assessed and the City can work with the relevant regulatory agencies to ensure that the impacts to the riparian corridor are less than significant. MitiQation Measure 3: As detailed enqineerinq is developed for the desiqn of the footinqs for the pedestrian footbridqe over Dublin Creek as envisioned in the Dublin Historic Park Draft Master Plan, the City shall work with the appropriate requlatory aqencies to ensure that impacts to the creek are minimized and addressed to the Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 24 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 satisfaction of the aqency. For the most part, the creek is proposed to be left in its natural state without any impacts to water quality through stormwater runoff or discharge, which will be retained and recharged on site in the Historic Park area. Because there is no land use intensification being proposed in the project area, because each development proposal is reviewed by the City Public Works Staff for compliance with the City's NPDES permit, and because discharge into the City's stormwater system is minimized through site design, it is not anticipated that any substantial adverse impact would occur or that permits from the U.S. Army Corps of Engineers or Regional Water Quality Control Board would be required. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Less than siqnificant impact. Because the creek and its associated flora is proposed to be left in its natural state, with the exception of the construction of the footbridge footings, no migration corridors should be interrupted. e-~ Conflict with any local policies or ordinances protecting biological resources, such as tree protection ordinances or conflict with the provision of an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional or state habitat conservation plan? Less than siqnificant impact and No impact. At this point, there are no trees proposed to be removed from the project area. A tree survey will be required as part of the detailed construction drawings for the Dublin Historic Park Draft Master Plan. The tree survey will plot the location of any tree that is subject to the City's Heritage Tree Ordinance and a tree removal permit would need to be obtained if a protected tree were proposed to be removed. Adherence to this requirement will ensure that the project's potential impacts to local policies and ordinances are negligible. Additionally, there are no adopted conservation plans in the project area with which the proposed project would be in conflict. Cultural Resources Would the project: (Sources: 1,2,4,5, 6, 7,9, 11, 12) a) Cause a substantial adverse impact in the significance of a historical resource as defined in CEQA Guidelines Sec. 15064.5? b) Cause a substantial adverse change in the significance of an archeological resource pursuant to Sec. 15064.5? c) Directly or indirectly destroy a unique paleontological resource or unique geologic feature?

PQt~ntially Less than Less than No Impact ~Jg1)(fiG:fJ~t significant Significant Impact with lr1Jpqct mitigatiQll X a) Cause substantial adverse change to a significant historic resource? Less than siqnificant. In 2003, the City contracted with architectural historians Page & Turnbull, Inc. to identify and map existing historic resources in the project area and to make recommendations for the continued preservation of those resources. The Historic Resources Identification Project (Final) was completed in January 2004 and it identified several resources that should be protected as development in the Dublin area continues. Some of these resources have special status at either the State or Federal level, and all of them are included in the Dublin Historic Resources Inventory, which is contained in the Draft Dublin Village Historic Area Specific Plan. Subsequent to the research conducted for the Historic Resources Identification Project, the Dublin Village Design Guidelines and the Historic Overlay Zoning District were adopted by the Dublin City Council (January and February 2005), which set forth the process to review new development in the project area and the guidelines under which modifications to identified historic resources would be considered. All development in the project area that impacts an identified historic resource, whether it be new construction or modifications to an existing building, should conform to the design guidelines (proposed to be incorporated as Section 7 of the Draft Dublin Village Historic Area Specific Plan), which were based on the Secretary of the Interior's Standards for the Treatment of Historic Buildings. Any historical resource renovation or rehabilitation project that is done consistent with the Secretary of the Interior's Standards can be classified as a categorical exemption under CEQA Guidelines Section 15331. At the time of any development application impacting an identified historic resource, Section 15064.5 (Determining the Significance of Impacts on Historical and Unique Archeological resources) of the CEQA Guidelines shall be consulted and all requirements of this section are required by State law to be met in the course of reviewing and implementing the project. Additionally, compliance with Chapter 8.62 of the Dublin Zoning Ordinance (Historic Overlay Zoning District) and the Design Guidelines (Section 7) of the Draft Dublin Village Historic Area Specific Plan will ensure that impacts to significant historic resources in the project area are less than significant. b-d) Cause substantial adverse change to significant archeological or paleontological resource or a unique geologic feature or disturb any human remains (either inside or outside a formal cemetery)? Less than siqnificant with mitiqation. In 2003, the City contracted with archeological firm William Self Associates, Inc. to identify and map archeological resources in the project area and to make recommendations for the continued preservation of those resources. The Archeological Assessment Report for the Donlon Way Area Specific Plan was completed in August 2003, and it summarized the type of and state of the archeological resources in the project area. Pursuant to a records Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 26 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 search through the Northwest Information Center (NWIC), there were found to be eight archeological sites within a quarter mile radius of the area, although no previously recorded prehistoric sites were known within the project area boundaries itself. In addition to the records search through the NWIC, William Self Associates also conducted a pedestrian survey of the project area. The pedestrian survey resulted in the identification of one previously unrecorded historic resource within the area boundary at Alamilla Springs (the exact details of the discovery are kept confidential in order to ensure that the resource is not disturbed). The pedestrian survey was also successful in identifying Archeological High Probability areas within the project area boundaries. Based on the existence of the archeological resources within and adjacent to the project area, the City's consultants, as well as the NWIC, believe that there is a moderate to high probability of identifying Native American archeological resources and a high probability of encountering historic-period archeological resources when the ground within the project area is disturbed, particularly within a 150 meter (493 foot) corridor centered on Dublin Creek and within the general vicinity of St. Raymond's Church, Pioneer Cemetery, and the Dublin Square Shopping Center site. Section 15126.4 of the CEQA Guidelines directs public agencies to avoid damaging effects on an archeological resource whenever possible. For a project that could impact an archeological resource, Section 15064.5 (Determining the Significance of Impacts on Historical and Unique Archeological resources) of the CEQA Guidelines will be consulted and all requirements of this section shall be met in the course of reviewing and implementing the project. In order to mitigate any potential impacts to resources in the project area, further archival and field study by an archeologist shall be undertaken prior to the construction of any development projects in the area in accordance with the recommendations of the William Self Associates document (pages 25- 28) and in consultation with the Public Works Director and Community Development Director, as detailed below: Mitigation Measure 4: In HiQh ArcheoloQical Probability Areas (includinQ a 150 meter (493 foot) corridor centered on Dublin Creek and within the qeneral vicinity of St. Raymond's Church. Pioneer Cemetery. and the Dublin Square ShoppinQ Center site), the permittinq of future qround disturbance shall include provisions for further archival and field study by an archeoloqist, archeoloqical testinq and, if necessary, archeoloqical monitorinq durinq construction. Mitigation Measure 5: Should preconstruction excavation or borinqs be conducted outside of the HiQh ArcheoloQical Probability Areas, but within the project area, a qualified archeoloqist shall monitor the work to define the presence or absence of buried resources in order to promote advance planninq for mitiQation purposes. Mitigation Measure 6: If a Native American artifact or human remains are identified durinQ any demolition or construction in the project area. work on the proiect shall cease immediately until those steps outlined in CEQA Guidelines Section 15064.5 (e) can be taken to the satisfaction of the Dublin Community Development Director. Project work may be resumed in compliance with the requirements of Section 15064.5 (e). Additionally. the County Coroner shall be contacted immediately and Section 7050.5(b) of the California Health and Safety Code (relatinQ to the discovery of Native American remains) should be implemented. Mitigation Measure 7: If an archeoloQical. prehistoric. or paleontoloqical resource is discovered durinQ any demolition or construction in the project area, work on the project shall cease immediately until a resource Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 27 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 protection plan conforminq to CEQA Guidelines Section 15064.5 (f) is prepared by a qualified archeoloqist and approved by the Dublin Community Development Director. Project work may be resumed in compliance with such Q.@)l Miti~ation Measure 8: Future roadwork or subsurface construction and maintenance within the Donlon Way road riqht of way and the portion of Dublin Boulevard within the proiect area shall include protocol for inadvertent discoveries made durinq construction, includinq the development of a resource protection plan conforminq to CEQA Guidelines Section 15064.5 (f), prepared by a qualified archeoloqist and approved by the Dublin Public Works and Community Development Directors. In the event of a discovery, proiect work may be resumed in compliance with such plan. The implementation of the above mitigation measures will ensure that the proposed project has a less than significant impact. Geology and Soils Would the project: (Sources: 1, 2, 3, 4, 13) Potentially Significant Impact No Impact miti ation a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Fault Zoning Map issued by the State Geologist or based on other known evidence of a known fault? ii) Strong seismic ground shaking? iii) Seismic-related ground failure, including liquefaction? iv) Landslides? b) Result in substantial soil erosion or the loss of topsoil? c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project and potentially result in on- and off-site landslide, lateral spreading, subsidence, liquefaction or similar hazards? d) Be located on expansive soil, as defined in Table 13-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? e) Have soils capable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of waste? x x X X X X X X The project area is located in the central portion of the Coast Ranges geomorphic province. The Coast Ranges are characterized by a series of parallel, northwesterly trending, folded and faulted mountain chains. Mt.

Expose people to strong seismic ground shaking, seismic-related ground failure (including liquefaction), or landslides? Less than siqnificant impact. Active earthquake faults within the region that influence earthquake susceptibility include the San Andreas, Hayward, Calaveras and Greenville Faults. The Calaveras Fault runs through Dublin generally along San Ramon Road, and has been traced to run across five of the properties within the project area, including APNs 941-0040-06-010 (Springs Apartments), 941-0040-06-016 (PetCo), 941-1550-01-012 (Shell Gas Station), 941-0550-05-02 (Heritage Park Office Complex), and 941-0550-01-010 (Vacant CalTrans property). Eight additional properties in the project area are within an Alquist-Priolo Fault Zone, which is approximately 500 feet on either side of the fault itself. The properties within the Fault Zone are those listed above in addition to the following: Parcel Number 941-1550-001-02 941-1550-003-02 941-1550-004 941-1560-001-01 941-1560-001-02 941-1560-002-02 941-1560-010-01 941-1550-002-02 ~ddress 11991 Dublin Boulevard 11891 Dublin Boulevard 11873 Dublin Boulevard 6506 Donlon Wa 6600 Donlon Wa 6572 Donlon Wa No address No address Signed into law in 1972, the Alquist-Priolo Earthquake Fault Zoning Act was signed into law with the intent to mitigate the hazard of surface faulting to structures for human occupancy. The Act requires that all residential construction within a fault zone has a comprehensive geologic investigation completed prior to building that shows that the fault does not pose a hazard to the proposed structure. Under moderate to severe seismic events, which are probable in the Bay Area, structures and facilities in the project area would be subject to damage caused by ground shaking. The General Plan contains policies in both the Conservation and Seismic Safety and Safety Element that will reduce the potential impact of ground failure and rupture. Adherence to these policies is required for any development in the City. Adherence to all requirements of the Uniform Building Code (UBC), and the Alquist-Priolo Earthquake Fault Zoning Act requirement that all construction plans in a fault zone incorporate the recommendations of a geotechnical investigation, will ensure that the project impacts are less than significant. It is a City standard that a registered Professional Engineer design the grading and foundation plans for any new construction. A Registered Geotechnical Engineer is is required to stamp and sign the grading and foundation plans certifying that they conform to the recommendations contained in the final geotechnical investigation, and this is verified when grading plans are reviewed and approved by the Building Division and the Public Works Department. Additionally, all structures proposed to be built within the Alquist-Priolo Fault Zone will be subject to additional near-fault structural requirements and the plans will be reviewed by the Building Division through the plan check process. b-d) Result in substantial soil erosion or the loss of topsoil, be located on a geologic unit or soil that is unstable, or be located on expansive soil?

The project area is underlain by stiff to very stiff clay soil to a depth of approximately 20 feet below ground surface. At depths greater than 20 feet, soil varies from medium dense to dense clayey and silty sands. Properties in the project area have been previously disturbed, graded, and paved in many instances to accommodate buildings, parking areas, roads, and other public and private improvements. For any construction project that is proposed in the project area, the Applicant will be required to obtain a grading permit from the City, and approval of the permit will be based on compliance with standard City development procedures. According to the United States Geologic Survey and the California State Department of Emergency Services, properties in the project area are all classified as having moderate susceptibility for ground liquefaction, as well as other seismic hazards. The following mitigation measure will serve to reduce the impacts of the project to less than significant: MitiQation Measure 9: A site-specific soils report/qeotechincal investiqation shall be required for any development proposal in the project area and shall be conducted by a California-reqistered qeoloqist or a California-reqistered enqineerinq qeoloqist. The report shall address the potential for expansive soils and qround liquefaction. Specific measures to reduce seismic hazards, expansive soils, and liquefaction hazards to a less than siqnificant level shall be included in the report and those measures shall be implemented as part of the site development. e) Have soils capable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of waste? No impact. The project area is served by a sewer system. Hazards and Hazardous Materials Would the project: (Sources: 1, 2, 3, 4, 6, 13) a) Create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials? b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous into the environment? c) Emit hazardous emissions or handle hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d) Be located on a site which is included on a list of hazardous materials sites complied pursuant to Government Code Sec. 65962.5 and, as a result, would it create a significant hazard to the public or the environment?

Less than siqnificant with mitiqation. It is not anticipated that any uses would be permitted in the project area that would entail activities that involve hazardous chemicals in any fashion. However, should that ever be the case, such materials would need to be used and stored in accordance with permits issued by the Bay Area Air Quality Management District, County Environmental Health Department and Alameda County Fire Department, so that a less-than-significant impact would therefore result. When demolition occurs in the area to implement the Dublin Historic Park Draft Master Plan, it shall be done in accordance with a City of Dublin demolition permit, which requires compliance with the Bay Area Air Quality Management District (BAAQMD) regulations. Because the shopping center proposed to be demolished was constructed in 1963, there is a possibility that either lead paint or asbestos is present in the building, both of which are considered hazardous materials. Adherence to the following mitigation measure will ensure that the presence and removal of those materials in that building, as well as any other building proposed to be demolished in the project area, has a less than significant impact on the environment. MitiQation Measure 10: Prior to demolition of any buildinq in the project area, the buildinq shall be sampled to determine if the buildinq contains lead paint and/or asbestos. If either of the materials are determined to be present. they shall be handles and disposed of as a hazardous material and in compliance with all applicable local, state, and federal requlations. The project site is not within one quarter mile of an existing school. d) Be located on a site which is included on a list of hazardous materials sites complied pursuant to Government Code Sec. 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Less than siqnificant impact. A Phase I Environmental Site Assessment was conducted for the Dublin Square Shopping Center site at 11759 Dublin Boulevard in January 2005, which is one of the properties within the project Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning Page 31 of 42 May 25, 2006 area. The study found that there are several facilities within the City that appear on regulatory agency lists, but that no facilities appear to be affecting the environmental conditions in the project area itself. Properties in the project area were used in the past for agricultural purposes, so there is a possibility that pesticide/herbicide contamination may be present near the surface, but it is not expected to be present in high levels due to the amount of time that has passed since agricultural operations were underway. e,f) Is the site located within an airport land use plan of a public airport or private airstrip? No Impact. The project site is not located within an airport land use plan or within the immediate vicinity of a public airport; therefore no impacts are anticipated regarding airport noise or crash hazards zones. g,h) Interference with an emergency evacuation plan, expose people and structures to a significant risk involving wildland fires, and are nearby residences intermixed with wildlands?

The City of Dublin is a co-permittee of the Alameda County Clean Water Program, which is a coordinated effort by local governments in the County to improve water quality in San Francisco Bay. In 1994, the San Francisco Bay Regional Water Quality Control Board issued a set of recommendations for New and Redevelopment Controls for Storm Water Programs. These recommendations include policies that define watershed protection goals, minimum non-point source pollution controls for site planning and post construction activities. Watershed protection goals are based on policies identified in the San Francisco Bay Basin Water Control Plan, which relied on Best Management Practices (BMPs) to limit pollutant contact with stormwater runoff at its source and remove such pollutants prior to being transported into receiving waters. Any development project in the City of Dublin requires the preparation of a project-specific Stormwater Pollution Prevention Program (SWPPP), ensuring that any surface water quality pollution impacts will be less-than-significant. As the implementation of the Historic Park Draft Master Plan is executed, one of the first phases of the project will be to demolish the existing Dublin Square Shopping Center site and remove the vast parking fields that surround the buildings. The removal of the buildings and the conversion of a shopping center site from a commercial use to a park use will reduce the amount of impervious surface in the project area. Park sites typically have a lot of pervious surface area, which allows for groundwater recharge and minimizes the potential for wastewater to drain, off the site. Additionally, the City will prepare a project-specific SWPPP which will address the development of the Historic Park in particular. For other properties in the project area, development proposals will be reviewed by the City's Public Works Department to ensure that stormwater runoff from the site is kept to a minimum through careful site design and on- site retention and recharge. The development of any new facilities in the project area will require that the project conforms to Alameda County Flood Control and Water Quality District, Zone 7 requirements and will meet the water quality standards of the City of Dublin's NPDES permit and the Alameda County Urban Runoff Clean Water Program. The future developer will be responsible for obtaining all permits necessary from Zone 7 prior to construction, and follow all provisions of the City's Stormwater Pollution Prevention Program (SWPPP) and the Water Quality Control Board requirements, listing Best Management Practices that reduce the potential for water quality degradation during construction and post-construction activities. Implementation of these required actions ensures that surface water quality pollution is a less than significant impact.

According to the Flood Insurance Rate Map published by FEMA (Community Panel Number 060705-0001 B), a bulk of the project area is located within a 500-year flood zone while a few of the parcels closest to Dublin Creek are within the 1 OO-year flood hazard area. The properties that are within the 1 OO-year flood hazard area are those that are proposed to be included in the Historic Park. The Historic Park area currently has two buildings that are in the flood hazard area, one being a church and the other a classroom/meeting/exhibit space. Neither of the buildings is used for residential purposes. The only new building proposed to be constructed in the Historic Park area is one 800 square foot pavilion/classroom building, which will be used intermittently and not for residential purposes. Therefore, the flood impacts to people or structures will be less than significant. Land Use and Planning Would the project: (Sources: 1,4,5, 7, 10, 11, 12) a) Physically divide an established community? b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat conservation plan or natural community conservation plan? Potentially Less than Less than No Impact Significant significant Significant Impact with Impact mitigation X X X a) Physically divide an established community? No impact. The project area is within an urbanized portion of Dublin and implementation of the project will not serve to physically divide the community in any fashion. The redesignation of parcels in the area from a Retail/Office General Plan land use category to Parks/Public Recreation will allow for the logical expansion of the City's Heritage Center and the development of a cohesive Historic Park. This will help to unify the City's historic core by connecting several of the City's historic buildings, archeological resources, and former historic sites into a single public space. b) Conflict with any applicable land use plan, policy or regulation? Less than siqnificant impact. The proposed project includes changes to several planning documents, including: Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Page 34 of 42 Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning May 25, 2006 · Amendment to the General Plan land use designation for five properties in the project area; · Amendment to the Zoning Map for two properties in the project area; · Adoption of the Draft Dublin Village Historic Area Specific Plan; · Amendment to the Parks and Recreation Master Plan Update (2004) · Adoption of the Draft Dublin Historic Park Draft Master Plan Approval of these changes ensures consistency between the proposed project and the City plans and regulations. c) Conflict with a habitat conservation plan or natural community conservation plan? No impact. No such plan has been adopted within the project area. There would, therefore, be no impact to a habitat conservation plan or natural community conservation plan. Mineral Resources Would the project (Sources: 1, 2, 4) a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general Plan, specific plan or other land use plan? No Impact x x No impact. The Conservation Element of the General Plan does not reference any significant mineral resources in the City, nor are any properties within the project area designated by the California State Department of Conservation, Division of Mines and Geology, as having deposits of minerals. Additionally, no mineral resources are shown on the State of California's maps of such resources, and therefore no impacts are expected as a result of project implementation. Noise Would the project result in: (Source: 1,2,3,4,5, 7, 11, 12) a) Exposure of persons to or generation of noise levels in excess of standards established in the general plan or noise ordinance, or applicable standards of other agencies? b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels? c) A substantial permanent increase in ambient noise levels in the project vicinity above existing levels without the project? d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels without the project?

The General Plan identifies that the normally acceptable maximum outdoor Ldn noise level is 60 dBA for neighborhood parks, and up to 65 dBA as conditionally acceptable. Noise measurements are expressed in decibels ("dBA"), which is the standard measure of sound pressure. New recreation facilities will need to be located in areas where the noise exposure level was not higher than 65 dBA in order to be in conformance with the General Plan. a-f) Would the project expose persons to or generate 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? Less than siqnificant impact. There are two possible noise impacts resulting from the proposed project: construction noise and operational noise. Construction noise is generated when a new facility is being built. Operational noise occurs when the facility is completed and is being used for its intended purpose. Operational noise is not expected to be a significant impact of any new park, residential building, office complex, commercial building, or business park because such noises generated are compatible with a suburban environment and will be mitigated at the project level by the conditions of approval for the project consistent with the City's noise standards. Such conditions typically include prohibitions on amplified sounds outside of the building and the like. Construction noise would be present at the time any new structure or facility is built, and short-term construction related noise could be expected. The City has adopted common practices for all construction and grading operations, and which are included in the construction documents for any construction project, to limit the hours of construction to 7:30 a.m. to 5 p.m., Monday through Friday, including the idling of equipment, unless the Director of Public Works approves alternative hours. Additionally, all equipment used on the construction site is to be in good, well-maintained condition, and mufflers, to minimize noise generation that could affect the residents in the project area. Therefore, noise-related impacts of the project will be less-than-significant. While there are limited noise impacts expected to be qenerated by the proposed project, there are existing noise impacts in the project area due to the proximity of Interstate 580 and the vehicular noise generated from that facility. One of the components of the Draft Dublin Historic Park Draft Master Plan is to install a soundwall along the freeway in a portion of the project area to reduce noise impacts to the existing Heritage Center and the future Historic Park expansion area. The soundwall will minimize noise impacts to future users of the Historic Park and cemetery expansion area and will improve the existing conditions near the Pioneer Cemetery, Murray Initial Study for the Draft Dublin Village Historic Area Specific Plan/General Plan Amendment, Draft Parks and Recreation Master Plan 2006 Update, Dublin Historic Park Draft Master Plan, and Area Rezoning Page 36 of 42 May 25, 2006 Schoolhouse, St. Raymond's Church, and the Dublin Creek Kennel/Hagan residence area. Although the General Plan does not contain noise exposure standards for an unique recreational/civic facility like the Historic Park, with the installation of the soundwall and the improvement that will provide to current noise impacts in the area, the impacts of the project will be less than significant, and in fact, will improve the situation. Additionally, the project area is not located within the vicinity of a private airstrip or within the boundaries of an airport land use plan area. Population and Housing Would the project: (Sources: 1,4, 12) a) Induce substantial population growth in an area, either directly or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? c) Displace substantial numbers of people, necessitating the replacement of housing elsewhere? tially ificant Impact Less than significant with miti ation Less than Significant Impact No Impact x x x No impact. Implementation of the proposed project will not induce additional growth in Dublin, as no new residential units are proposed that are not currently permitted under the existing project area General Plan land use designations and Zoning Districts. Therefore, no population growth impacts are anticipated that have not already been assessed in the General Plan. The implementation of the proposed project will not displace any existing housing units or people, and therefore the project will have no impact. Public Services (Sources: 1,3,4, 11, 12) Potentially Significant Impact Less than significant with miti ation Less than Significant Impact a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Fire protection?

Any future development projects in the area will pay impact fees appropriate to the type of project. a) Would the project increase the use of existing neighborhood or regional facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational facilities or require the construction or expansion of recreational facilities that might have an adverse physical effect on the environment? Potentially Less than Less than No Impact Significant significant Significant Impact with Impact mitigation X X Recreation (Sources: 1,3,4, 10, 11, 12 No Impact. The proposed project does not include residential development that is not already anticipated under the General Plan, so there would be no increase in the need for or impact on recreational facilities. The project would add a much-needed recreational facility to the Dublin community, thereby increasing the City's recreational resources and facilities to serve the community. No adverse impact related to recreational facilities will result, but rather, the park development will provide more recreational activities and facilities for the public's use. This Initial Study is studying the impacts of developing a new park in the project area and the possible effects on the environment that the park might have, but the proposed project in and of itself will not have a negative impact on recreational facilities in the project area, and in fact will create additional recreational opportunities. Transportation and Traffic Would the project: (Sources: 1,2,3,4, 11, 12) Potentially Significant Impact Less than significant with Less than nt No Impact a) Cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system (i.e. result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads or congestion at intersections)? b) Exceed, either individually or cumulatively, a level of service standard established by the County Congestion Management Agency for designated roads or highways? c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? d) Substantially increase hazards due to a design feature (e.g. sharp curves or dangerous intersections) or incompatible uses, such as farm equipment?

Significant Impact Less than No Impact Significant frnpact with miti ation x x x No impacts. No impacts are anticipated with regard to traffic or parking for the proposed project. Existing and proposed roadway improvements have been designed and sized to provide adequate transportation facilities and transit modes with sufficient capacity for the existing and proposed uses. No land use intensification is proposed for properties in the project area, though there is the capacity for the overall maximum development potential in the area to increase due to the fact that many of the sites are currently developed at less than the maximum intensity permitted in the General Plan, as discussed in the previous section on Air Quality. However, all of this capacity exists today, without the land use changes proposed in the Specific Plan (which actually decreases the development potential because of the shift from Retail/Office to Parks/Public Recreation), and recreational facilities - even those with classroom and small outdoor stage facilities - are typically not large traffic generators. They are typically not peak-hour trip generators, and are primarily local- serving. Vehicle trips are spread throughout the day, and in fact the concentration of trips tends to be during non- peak hour times such as afternoons, evenings, and weekends, which minimizes potential impacts to the city circulation systems. Additionally, both the Draft Dublin Village Historic Area Specific Plan and the Draft Dublin Historic Park Draft Master Plan call for several public improvements to be made to the streets and sidewalks in the project area, which will increase pedestrian safety. Adequate parking for the proposed Draft Dublin Historic Park Draft Master Plan is proposed, including the construction of a new parking lot and the addition of on-street parking on Donlon Way, and therefore, no adverse impacts relative to parking are anticipated. Utilities and Service Systems Would the project (Sources: 1,3,4, 11, 12) a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects?

Electrical and natural gas power: Pacific Gas and Electrical Company . Water supply and sewage treatment: Dublin San Ramon Services District . Storm Drainage: City of Dublin . Solid waste disposal: Amador Valley Industries The proposed project will not result in a demand for new water and wastewater services for potable or irrigation water, because no land use intensification is proposed for properties in the project area and existing service infrastructure can be used. It is not anticipated that utility service beyond that which is already provided to the area will be required. As is typically the case with new development applications in the City, individual development proposals will be reviewed on a case-by-case basis by City Staff as well as utility providers to ensure that services can be provided as needed. It is not anticipated that development in the project area will require the extension of additional services, and the impacts to utilities and service systems will not be significant. Future development in the project area will be consistent with General Plan policies, allowing necessary utilities and services to be provided without significant impact. When construction drawings are submitted for specific future projects, City Departments and other governmental agencies will review plans in accordance with adopted regulations to determine feasibility and suitability.
