The certified EIR consisted of a Draft EIR and Responses to Comments bound volumes, as well as an Addendum dated May 4, 1993, assessing a reduced developrffent and project alternative. The City Council adopted Resolution No. 53-93 approving a General Plan Amendment and Specific Plan for the reduced area alternative on May 10, 1993. On August 22, 1994, the Cit3 Council adopted a second Addendum updating wastewater disposal plans for Eastern Dublin. The Eastern Dublin EIR evaluated the potential environmental effects of urbanizing Eastern Dublin over a 20 to 30 year period. Since certification of the EIR, many implementing projects such as Dublin Ranch have been proposed, relying to various degrees on the first-tier certified E!R. A subsequent Negative Declaration was adopted for the Dublin RanCh Planning Areas B-E November 18, 1997 (City CounCil Resolution No. 140-97). A Mitigated Negative Declaration was later approved for Planning Area F of Dublin Ranch in 2000 (SCH # 99112040, PA #98-068, adopted by Dublin City Council Resolution No. 34-00 on February 15, 2000. · This Addendum has been prepared pursuant to CEQA Guidelines Section 15164 for the current DUblin Ranch Planning Area B, F and E project, as described below. Project Description and Prior Approvals The City of Dublin approved development of Dublin Ranch Planning Areas B through E in November 1997. The approvals included a General Plan and Specific Plan Amendment, and PD-Planned Development rezoning/Stage 1 Development Plan for up to 1875 dwellings units and other non-residential land uses. Subsequent subdivision maps were later approved to subdivide the land into smaller lots. A Mitigated Negative Declaration was approved by the City of Dublin on February 15, 2000 for Dublin Ranch Planning Area F. This project included an amendment to the Dublin General Plan and Eastern Dublin Specific Plan to reconfigure land uses within Planning Area F, as well as a Stage 1 Planned Development rezoning, a Tentative Tract Map, formation of an assessment district, and modifications to an exiSting Development Agreement. This Addendum refers to these approvals as "Dublin Ranch Planning Area B, F and E approvals." The current application proposed a further Amendment to the General Plan and Eastern Dublin Specific Plan to reallocate land uses within the three Planning Areas totaling 289.3 acres of land, approval of a Stage 1 PD-Planned Development for this area and a Stage 2 EXHIBIT ATTACHMENT I Planned Development for approximately 88.5- acres of the project area. This Addendum refers to these applications collectively as "the Project", which is further described in the Initial Study referenced below. Prior CEQA Analyses and Determinations Eastern Dublin EIR. The Project is within the Eastern Dublin planning area, which was the subject of the Eastern Dublin EIR, certified in 1993. The EIR analyzed the potential effects of future urban development planned for a then-largely undeveloped area east of the then- existing city of Dublin. Numerous environmental impacts were identified and numerous mitigations adopted upon approval of the Eastern Dublin General Plan Amendment and Specific Plan. For identified impacts that could not be mitigated to insignificance, the City Council adopted a Statement ,of Overriding Considerations, All previously adopted mitigation measures for development of Eastern Dublin that are applicable to the Project and Project site continue to apply to the currently proposed Project. The Eastern Dublin EIR is incorporated herein by reference. Dublin Ranch Planning Area B-E Negative Declaration. Development of Planning Areas B-E of the Dublin Ranch was further reviewed in a Negative Declaration assessing the potential for site-specific impacts of the proposed development. Tiering from the program- level review in the Eastern Dublin EIR, the ND examined the potential for significant impacts not addressed n the prior EIR. The City of Dublin approved the Negative Declaration through Resolution No. 140-97 on November 18, 1997, which resolution is incorporated herein by reference. Relying on the Eastern Dublin EIR and Dublin Ranch Planning Area B-E Negative Declaration, the City Council approved the Dublin Ranch proposal. Portions of Dublin Ranch PAs B-E have been developed and~or are currently under construction. The development program associated with Dublin Ranch Planning Areas B-E includes a variety of land use types, including campus office, community commercial, residential at varying densities, schools, parks, open spaces and rural residential/agricultural uses. The current Project includes the westerly portion of Area E, and residential and community park portions of Area B north of Central Parkway. City Council Resolution No. 140-97, that approved the Negative Declaration for these Dublin Ranch Planning Areas, contained findings that the Project did not constitute a change from the Eastern Dublin General Plan Amendment and Specific Plan and that there wase no new information of substantial importance to the GPA, the EDSP or the Project that could not have been known when the Eastern Dublin Program EIR was certified in 1993. Dublin Ranch Planning Area F Mitigated Negative Declaration. Development of Planning Area F of the Dublin Ranch was reviewed in a Mitigated Negative Declaration assessing the potential for site-specific impacts of the proposed development. Tiering from the program- level review in the Eastern Dublin EIR, the MND examined the potential for significant impacts not addressed in the prior EIR. The City of Dublin approved the Mitigated Negative Declaration through Resolution No. No. 34-00 on February 15, 2000, which resolution is incorporated herein by reference. Relying on the Eastern Dublin EIR and Dublin Ranch Page 2 I Planning Area F Mitigated Negative Declaration, the City Council approvecl the Dublin Ranch Planning Area F proposal. The development program associated with Dublin Ranch Planning Area F included minor modifications to land uses and the location of roadways through the Planning Area. City Council Resolution No. 34-00, that approved the Mitigated Negative Declaration for Planning Area F, contained findings that the Project did not constitute a change from the Eastern Dublin General Plan Amendment and Specific Plan and that there was no new information of substantial importance to the GPA, the EDSP or the Project that could not have been known when the Eastern Dublin Program EIR was certified in 1993. Current CEQA Analysis and Determination that an Addendum is Appropriate for this Project. Updated Initial Study. The City of Dublin has determined that an Addendum is the appropriate CEQA review for the proposed Project. Prior to making this determination, the City reviewed the Eastern Dublin Ell[, the previous Negative Declaration for Pas B-E and the Mitigated Negative Declaration for Planning Area F, to determine if any further environmental review was required for the proposed General Plan/EDSP Amendment and Stage 1 and Stage 2 Planned Development rezonings. The City prepared an updated Initial Study dated February 9, 2004, and incorporated herein by reference. Through this Initi.al Study, the City has determined that no subsequent EIR, or negative declaration is required for this Project. No Subsequent Review is Required per CEQA Guidelines Section 15162. CEQA Guidelines Section 15162 identifies the conditions requiring subsequent environmental review. After a review of these conditions, the City has determined that no subsequent EIR or negative declaration is required for this Project. This is based on the following analysis: a) Are there substantial changes to the Project involving new or more severe significant impacts? There are no substantial changes to the Project analyzed in the Eastern Dublin EIR, the Mitigated Negative Declaration for Dublin Ranch PA F, and the Dublin Ranch PA B-E Negative Declaration. The Project proposes to reconfigure approved uses, but is consistent with the overall types of land uses and densities allowed in the Dublin General Plan and Eastern Dublin Specific Plan. These changes would include: 1. This General Plan Amendment/Eastern Dublin Specific Plan Amendment proposes to redesignate land slated for-High School use to Middle School use. The High School site originally designated for Areas E and F has been deemed unnecessary by Dublin Unified School District (DUSD). In accordance with the prior wishes of DUSD, the land use designation for the portion of the High School site occurring in Area F, consisting of 30.6 gross acres, was previously changed to Middle School in conjunction with PA-98-068, leaving the remainder of the High School site (20.0 acres in Area E) unchanged. DUSD would now tike to develop Page 3 a Middle School on a site further to the north, on a portion of the remnant High School-designated parcel abutting South Dublin Ranch Drive and a portion of the previously planned Middle School Site. As a result of this change, a 24.2-acre site designated for Middle School use would be created. 2. This GPA/EDSP Amendment proposes to redesignate land slated for High School use to Public/Semi-Public use. The portion of the previouslY designated High School parcel located south of the newly proposed Middle School site would serve as a replacement parcel for the Public/Semi-Public sites at the intersection of Central Parkway and Grafton Street.' The 6.3-acre replacement parcel allows a larger range of potential uses by Providing a larger land area and consolidating two smaller parcels of land. 3. This GPA/EDSP Amendment proposes to redesignate land at the Central Parkway/Grafton Street intersection currently slated for Public/Semi-Public use to Medium Density Residential use. Concerns have been raised about the physical suitability of the two Public/Semi-Public parcels of approximately two acres each planned and approved for the intersection of Central Parkway and Grafton Street to accommodate a wide enough range of potential public/semi-public uses due to their small size. To remedy this, theSe parcels are proposed to be replaced by one larger parcel to the north of Gleason Drive. 4. This GPA/EDSP Amendment proposes to redesignate land slated for Middle School use to Medium Density Residential use. With DUSD interested in developing the new Middle School on the northerly portion of the land originally slated for a high school, the land abutting Gleason Drive would be changed to a Medium Density Residential use designation and developed as a neighborhood. This land use redesignation would be Consistent with adjacent residential land use designations and the neighborhood CNeighborhood Fl) will contribute to the residential nature of the school setting and serve as a buffer between the Middle School and Gleason Drive, an east-west arterial road connecting Tassajara Road and Fallon Road. 5. This GPA/EDSP Amendment proposes to redesignate land within Area B, which is north of Gleason and west of Fallon (presently slated for Medium Density Residential use) to Low Density Residential use. The small size and hillside nature of the approximately 1 O-acre parcel near the intersection of Fatlon Road and Gleason Drive greatly limit the viability of Medium Density development in the area. This parcel would be combined with the land designated Low Density Residential immediately to the west, allowing it to be developed as a more efficient and cohesive neighborhood. This neighborhood (Neighborhood F2) would be consistent in density and character with existing neighborhoods to the north and east. 6. This GPA/EDSP Amendment proposes to reconfigure land within Area B slated for Open Space/Stream Corridor use, Community Park use and Medium Density Page 4 Residential use south of Gleason Drive. Recent revisions to the configuration of the Community Park adjacent to Fallon Road have necessitated changes to the alignment of both Fallon Road and the north-south collector (Lockhart Street) along the western park boundary and to the configuration of the Open Space/Stream Corridor and the Medium Density Residential Neighborhoods west of the park. The Dublin City Council approved the changes to the size and configuration of the Community Park on October 7, 2003. Based on this, the Community Park portion of the Amendment Area would be expanded from 52.0 gross acres to approximately 65.9 gross acres; the Open Space/Stream Corridor will be expanded from 4.8 gross acres to 7.9 gross acres. With the westward realigament of Fallon Road and the expansion of the Community Park and adjacent Open Space/Stream Corridor, Medium Density Residential neighborhoods in the eastern portion of the Amendment Area south of Gleason Drive would be reduced by approximately 7.6 gross acres. The reduction in Medium Density Residential use in this area is necessary to accommodate the entire Community Park and Stream Corridor programs as well as a re-aligned north-south collector street (Lockhart Street) west of Fallon Road. Based on the land use changes encompassed in this amendment, Keegan Street would no longer be extended north from Central Parkway to Gleason Drive. b) Are there substantial changes in the conditions which the Project is undertaken invOlving new or more severe significant impacts? There are no substantial changes in the conditions assumed in the Eastern Dublin EIR, 1997 Negative Declaration for PA B-E and the 2000 Mitigated Negative Declaration for PA F. Although special-status species are present on a portion of the Project site, numerous previous biological studies have been conducted to identify their respective locations, and related mitigations have already been implemented. The Corps of Engineers has also issued necessary 404 permits to allow filling of wetlands within the Project area subject to mitigation for loss of these wetlands. c) Is there new information of substantial importance, which was not known and could not have been known at the time of the previous EIR that shows the Project will have a significant effect not addressed in the previous EIR; or previous effects are more severe; or, previously infeasible mitigation measures are now feasible but the applicant declined ' to adopt them; or mitigation measures considerably different from those in the previous EIR would substantially reduce significant effects but the applicant declines to adopt them? There is no new information showing a new or more severe significant effect. The applicant's plans for Planning Areas B, F and E would be consistent with Eastern Dublin EIR mitigation measures, mitigation measures previously adopted, and U. S. Army Corps of Engineer and other agency permits. d) If no subsequent EIR-level review is required, shoUld a subsequent negative declaration be prepared? No subsequent negative declaration or mitigated negative declaration is required because there are no impacts, significant or otherwise, of the Project beyond those identified in the Eastern Dublin EIR and previous negative declarations. Page 5 Conclusion. This Addendum is adopted pursuant to CEQA Guidelines Section 15164 based on an Initial Study dated February 9, 2004. The Addendum and Initial Study reviews the proposed redesignation and reconfiguration of land uses as discussed above. Through the adoption of this Addendum and related Initial Study, the City determines that the above minor changes in land uses do not require a subsequent EIR or negative declaration under Guidelines Section 15162. The City further determines that the Eastern Dublin EIR, previous negative declarations and this Addendum/Initial Study adequately address the potential environmental impacts of the Proposed Project. As provided in Section 15164 of the Guidelines, the Addendum need not be circulated for public review, but shall be considered with the prior environmental documents before making a decision on this project. The Initial Study, Eastern Dublin EIR, Dublin Ranch Planning Area B-E Negative Declaration, Dublin Ranch Planning Area F Mitigated Negative Declaration are all available for public review in the Community Development Department, Dublin City Hall, 100 Civic Plaza, Dublin CA.

The.Initial Study consists of a completed environmental checklist and a brief exPlanation of the environmental topics addressed in the checklist.~ Applicant Chang Su-O-Lin, H. Yao Lin and H. L:":Lin C/O James Tong 4690 Chabot Drive, Suite 100 Pleasanton, CA 94588 Contact Person MacKay & Somps 5142 Fr~anklin Drive, Suite B Pleasanton CA 94588 Attn: Dave Chadbourne Project Location and Context The project site is comprised of portiOns of Area B, F and E of Dublin Ranch. The Project is located within the larger East Dublin area, located south of Dublin Ranch Phase 1 development and north of Central Parkway. The Project area consists of approximately 285 acres of land and is a part of a larger portion of the Dublin Ranch, which also includes Planning Areas G and H to the south. ' Exhibit 1 depicts the location of the Project area in context of the larger City of Dublin and Exhibit 2 depicts its relation to Eastern DUblin as well as neighboring Planning Areas. The Project site is located within the Eastern Dublin Specific Plan/General Plan area. This Specific Plan/General Plan was adopted by the City of Dublin in 1993 for the purpose of directing long-term land use, CircUlation, infrastructure and environmental protection for 3,328 acres of land located east of the central portion of Dublin and north of the 1-580 freeway. At full build-out, the Eastern Dublin planning area would allow a range of residential, commercial office, employment and open space uses. The Project area is also part of Dublin Ranch, the largest landholding within the Eastern Dublin Specific Plan area. Dublin Ranch contains approximately 1,310 acres of land and is being planned to accommodate approximately 5,760 residential dwellings and approximately 2.5 City of Dublin Page 2 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 million square feet of office and retail floor space. Dublin Ranch is also being planned to contain . .. a range of schools, parks and other public areas. ~ The Project area is currently vacant land. No residences or other structures exist within the boundaries of the Project Area. The low rolling hills are covered primarily with non-native grassland. The existing topography across the site is varied with the greatest elevation difference occurring towards the eastern side of the project, south of Neighborhoods L4 and L5 of Dublin Ranch Phase I. At this location, a hillside exists along the boundary with Phase I with elevation differences of 30 to 50 feet. Elevations across the Project area generally fall from north to south. Construction of Medium High and High Density Residential projects associated with the planned Village Center are currently occurring to the south of the Project area. To the east, development associated with Dublin Ranch Area A is currently in progress, including single family residential neighborhoods, an 18-hole golf course, and the expansion of Fallon Road. To the north and west, the construction of Dublin Ranch Phase I is nearly complete, with Low and Medium Density Residential neighborhoods, an elementary school parcel (not yet developed), a neighborhood park, open space/stream corridor, and other recreational amenities. Project Description The proposed Project would include two separate but related actions: a) an amendment to the Eastern Dublin Specific Plan/General Plan and consideration of a PD rezoning/Stage 1 Development plan for portions of Planning Areas B, F and E that would include approximately 289 acres of land (the "Amendment Area"), and b) a PD rezoning/Stage 2 PD-Development Plan for Area F North that would include approximately 86.9 acres of the larger area described in "a." (the "Development Area"). These are described more fully below. ~ Specific Plan~General Plan Amendment Several Amendments are proposed to the Eastern Dublin Specific Plan/General Plan that would slightly reconfigure and reorient previously approved land uses in Planning Areas B, F and E. The effect of the proposed amendments would be to reduce the total number of dwellings units by 136 units and the size of the three Planning Areas by 3.9 acres of land, as shown in Table 1. Previous environmental review and analysis has been completed in terms of a Program EIR for all of the Eastern Dublin Specific Plan area as well as individual Negative Declarations and Mitigated Negative Declarations for each of the Dublin Ranch Planning Areas affected by this proposed Project. Mitigation measures have been established in these previous environmental documents that would continue to apply to this Project. More specifically, the Amendments would include the following: 1. This General Plan Amendment/Eastern Dublin Specific Plan Amendment proposes to redesignate land slated for High School use to Middle School use. The High School site originally designated for Areas E and F has been deemed unnecessary by Dublin Unified School District (DUSD). In accordance with the prior wishes of DUSD, the land use designation for the portion of the High School site occurring in Area F, consisting of 30.6 gross acres, was previously changed to Middle School in conjunction with PA-98-068, leaving the remainder of the High School site I20.0 acres in Area E) unchanged. DUSD would now like to develop a Middle School on a site further to the north, on a portion of the remnant High School-designated parcel abutting South Dublin Ranch Drive and a portion of ..~ City of Dublin Page 3 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 the previously planned Middle School Site. As a result of this change, a 24.2-acre site designated for Middle School use would be created. 2. This GPA/EDSP Amendment proposes to redesignate land slated for High School use to Public/Semi-Public use. The portion of the previously designated High School parcel located south of the newly proposed Middle School site would serve as a replacement parcel for the Public/Semi-Public sites at the intersection of Central Parkway and Grafton Street. The 6.3- acre replacement parcel allows a larger range of potential uses by providing a larger land area and consolidating two smaller parcels of land. 3. This GPA/EDSP Amendment proposes to redesignate land at the Central Parkway/Grafton Street intersection currently slated for Public/Semi-Public use to Medium Density Residential use. Concerns have been raised about the physical suitability of the two Public/Semi-Public parcels of approximately two acres each planned and approved for the intersection of Central Parkway and Grafton Street to accommodate a wide enough range of potential public/semi- public uses due to their small size. To remedy this, these parcels are proposed to be replaced by one larger parcel to the north of Gleason Drive. 4. This GPA/EDSP Amendment proposes to redesignate land slated for Middle School use to Medium Density Residential use. With DUSD interested in developing the new Middle School on the northerly portion of the land originally slated for a high school, the land abutting Gleason Drive would be changed to a Medium Density Residential use designation and. developed as a neighborhood. This land use redesignation would be consistent with adjacent residential land use designations and the neighborhood (Neighborhood Fl) will contribute to the residential nature of the schoo!.s~tfing and serve as a buffer between the Middle School and Gleas~h' Drive, an east-west arterial road connecting Tassajara Road and Fallon Road. 5. This GPA/EDSP Amendment proposes to redesignate land within Area B, which is north of Gleason and west of Fallon (presently slated for Medium Density Residential use) to Low Density Residential use. The small size and hillside nature of the approximately 10-acre parcel near the intersection of Fallon Road and Gleason Drive greatly limit the viability of Medium Density development in the area. This parcel would be combined with the land designated Low Density Residential immediately to the west, allowing it to be developed as a more efficient and cohesive neighborhood. This neighborhood (Neighborhood F2) would be consistent in density and character with existing neighborhoods to the north and east. 6. This GPA/EDSP Amendment proposes to reconfigure land within Area B slated for Open Space/Stream Corridor use, Community Park use and Medium Density Residential use south of Gleason Drive. Recent revisions to the configuration of the Community Park adjacent to Fallon Road have necessitated changes to the alignment of both Fallon Road and the north- south collector (Lockhart Street) along the western park boundary and to the configuration of the Open Space/Stream Corridor and the Medium Density Residential Neighborhoods west of the park. The Dublin City Council approved the changes to the size and configuration of the Community Park on October 7, 2003. Based on this, the Community Park portion of the Amendment Area would be expanded from 52.0 gross acres to approximately 65.9 gross acres; the Open Space/Stream Corridor will be expanded from 4.8 gross acres to 7.9 gross acres. With the westward realignment of Fallon Road and the expansion of the Community Park and adjacent Open Space/Stream Corridor, Medium Density Residential neighborhoods CitY of Dublin Page 4 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 in the eastern portion of the Amendment Area south of Gleason Drive would be reduced by approximately 7.6 gross acres. The reduction in Medium Density Residential use in this area is necessary to accommodate the entire Community Park and Stream Corridor programs as well as a re-aligned north-south collector street (Lockhart Street) west of Fallon Road. Based on the land use changes encompassed in this amendment, Keegan Street would no longer be extended north from Central Parkway to Gleason Drive.' Table 1 shows aPproved land uses in the Project area compared with land uses proposed as part of the Eastern Dublin Specific Plan and General Plan Amendment. Exhibit 4 depicts the location and extent of the requested change as well. Land use acreages have been somewhat reduced in this application due to a re-alignment of Fallon Road to protect biological resources on the Jordan property and more accurate base mapping of the Project site.

PD Rezoning/Stage 1 Development Plan (Planning Areas B, F & E) An application has also been filed for a PD rezoning/Stage 1 Development Plan apProval pursuant to the City of Dublin planned Development (PD) Zoning District. Pursuant to the PD Ordinance, property owners must submit a request for Stage 1 Development Plan approval. A Stage 1 Development Plan establishes land uses within a distinct geographic area, includes a plan of proposed land uses by type and density of use, contains a master landscape plan and development Phasing plan. City of Dublin Page 5 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 The Stage 1 Planned Development Rezone covers approximately 289 acres of land, encompassing portions of Areas B, F, and E of Dublin Ranch. This area is bordered by existing Phase 1 residential neighborhoods to the north, an existing neighborhood (Mi) and Dublin Land Company lands to the west, Central Parkway to the south, and Fallon Road to the east. This land (referred to in the General Plan/Eastern Dublin Specific Plan Amendment (GP/EDSPA) application booklet as the Amendment Area) is shown in greater detail in the Vesting Tentative Subdivision Map and Site Development Review sections. The Stage 1 Development Plan submitted for the Project indicates that the planning area would have an "upscale rural" theme, which would reflect the agrarian past of eastern Dublin. Planned design details would include use of rail fencing, stone pilasters, plantings of tree groves to reinforce the rural theme. The Stage 1 PD-Planned Development area is composed of five distinct sub-areas. These are separated from each other by Gleason Drive, an arterial running east-west through the project area, and north-south collector streets including Lockhart, running south from Gleason to Central Parkway, and Grafton Street, running through the Stage 1 Area from Antone Way north of the Stage 1 area to the Village Center to the south. There are two sub-areas north of Gleason Drive. Of these, the sub-area west of Grafton contains approximately 25.2 acres (gross*) for a Middle School site, a 6.3-acre parcel for Public/Semi- Public uses, 2.2 acres of Open Space/Stream Corridor, and a 20.0-acre Medium Density Residential neighborhood. The sub-area east of Grafton contains a 33.4-acre Low Density Residential neighborhood and an Open Space/Stream Corridor of 1.4 acres. The rer~aining three sub-areas are located south of ~leason Drive and are separated by Grafton and Lockhart Streets. The sub-area west of Grafton consists of approximately 42.0 acres of Medium Density Residential, with a 2.0-acre Neighborhood Square centrally located within the residential area, and approximately _-acre of Open Space Corridor (multi-use trail) along the western side of Grafton Street. The sub-area between Grafton and Lockhart Streets contains approximately 63.0 acres of Medium Density Residential, a 10.0-acre Elementary School site, and a 5.6-acre Neighborhood Park. The sub-area east of Lockhart Street contains a Community Park (65.9 gross acres) and a 7.9-acre Open Space/Stream Corridor area. Grading activities would occur within the Project Area to accommodate planned land uses, roads and utilities. Mass grading of a portion of the Project site is currently underway or has been recently completed based on issuance of a U.S. Army Corps of Engineers fill permit. Dublin San Ramon Services District (DSRSD) will provide water and wastewater service for the Amendment Area. These services are planned in accordance with the DSRSD Eastern Dublin Facilities Master Plan (and/or subsequent revisions). An existing water storage reservoir provides water service for the Amendment area. Distribution mains are planned to be located in all streets. Final locations and sizing of these facilities will be in accordance with the standards and recommendations of DSRSD. * Acreage figures given for land uses are gross acreages unless otherwise noted. Gross acreage is measured to the centerline of arterial/collector streets. City of Dublin Page 6 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 Sewer service for the Amendment Area will require connection to DSRSD's existing sewer system. Gravity sewer mains have been extended easterly in Gleason Drive from Tassajara Road into the Development Area. Final sizing and location of sewer facilities will be determined during final design. The storm drain system for the Amendment Area will consist of major backbone facilities and local facilities as defined by the Master Storm Drain Study for Dublin Ranch. The backbone facilities will generally consist of larger diameter pipes networked throughout the site located in the major streets. These larger collector pipes will ultimately connect to box culverts that will direct the flow towards the existing G-3 channel, a Zone 7 facility located at the south end of Dublin Ranch. Local facilities will generally consist of smaller diameter pipes connecting individual neighborhoods to the collector system. The locations of proposed storm drain facilities are shown on the tentative maps for the individual neighborhoods. Dublin's Inclusionary Zoning Ordinance currently requires 12.5% of all housing to be affordable to those of very low, low and moderate incomes. This project will comply with the Inclusionary Zoning Ordinance requirements by constructing a proportionate share of the affordable units within the Fairway Ranch Residential Community. Construction of the Fairway Ranch project, located within Area B of Dublin Ranch between Central Parkway and Dublin Boulevard, will commence in 2004. The project applicant indicates that land uses and infrastructure would be phased over a number of years to ensure that roads and other infrastructure facilities would be available to support land uses as they are needed. Preliminarily, construction of initial phases would commence in 2004 with construction anticipated to be completed over the next several years. PD Rezoning/Stage 2 Development Plan (portion of Planning Area F North) The Stage 2 Planned Development Rezone (referred to as the Development Area in the GP/EDSPA section) covers an area of approximately 88.5 acres comprised of the portion of the Stage 1 Planned Development Area north of and including Gleason Drive, within Planning Area F North. The Stage 2 PD-Planned Development area would be comprised of five different land uses: Open Space/Stream Corridor, Medium Density Residential, Low Density Residential, Middle School and Public/Semi Public. There are two proposed Open Space corridors in the Project Area, each with a stream and a 12' wide multi-use trail running through it. The Open Space/Stream Corridor area on the west side of Fallon Road is 1.4 acres* and is a continuation of the existing corridor located adjacent to Fallon Road and Phase 1 neighborhoods; the one west of Grafton Street is 2.2 acres and continues the existing corridor on the west side of Grafton. The Development Area also contains two residential neighborhoods. The F1 Medium Density Residential neighborhood is proposed to consist of 119 single-family detached homes on approximately 20.0 acres, at a'density of 6.0 dwelling units to the acre (du/ac). The F2 Low Density Residential neighborhood is proposed as 121 single-family detached homes on approximately 33.4 acres at a density of approximately 3.5 du/ac. A Middle School site occupies 25.2 acres in the northwest corner of the Stage 2 Planned Development Area. Finally, a parcel of 6.3 acres in the southeastern area of the Stage 2 Planned Development Area is to be reserved for * Acreage figures given for land uses are gross acreages unless otherwise noted. Gross acreage is measured to the centerline of arterial/collector streets. City of Dublin Page 7 Initial Study/Dublin Ranch Areas B/F/F: February 2004 PA 01-037 Public/Semi-Public uses. This Public/Semi-Public (P/SP) site is to replace two P/SP sites totaling 3.9 acres, at the intersection of Grafton Street and Central Parkway, which are proposed to be rezoned to Medium Density Residential under the Stage 1 P.D. A comparison of acreages allocated to designated land uses within the proposed Stage 2 Planned Development Land Use Plan and the same area of the approved Specific Plan is included in Table 2.

City of Dublin Page 8 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 Other Entitlements The applicant has also requested approval of a master tentative tract map to subdivide the Project Area into smaller parcels of land for sale to future builders. In addition, individual vesting tentative maps for two neighborhood within Area F North (north of Gleason Drive) have also been submitted for review and approval. A tentative map package is being reviewed concurrently with the Specific Plan/General Plan Amendment application and PD rezone, however, the tentative maps may not be acted upon until other applications have been acted upon. Site Development Reviews (SDRs) applications have also been submitted for the Development Area.

A Negative Declaration will be prepared. ~ I find that although the proposed project may have a significant effect 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 earlier analysis as described on the attached sheets, if the effect is a "potentially significant impact" or "potentially significant unless mitigated." An Environmental Impact Report is required, but' must only analyze the effects that remain to be addressed. X I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR, Negative Declaration and Mitigated Negative Declaration pursuant to applicable standards, (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that' are imposed on the proposed project, or (c) a Statement of Overriding Considerations has been adopted by the Dublin City Council. An Addendum has been prepared to the previous CEQA reviews. (reference "Earlier Analysis" section of this Initial Study on page __).

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); or, in this case, there is no impact beyond those identified in prior CEQA reviews. 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 m 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. Portions of the environmental setting, project impacts and mitigation measures for this Initial Study refer to environmental information contained in the 1993 Eastern Dublin Specific Plan/General Plan Amendment Environmental Impact Report. (SCH 91103064). This document is referred to in this Initial Study as the "Eastern Dublin EIR." Copies of this document are available for public review at the City of Dublin Planning Department, 100 Civic Plaza, Dublin CA, during normal business hours. A Negative Declaration was previously approved for Planning Areas B through E of the Dublin Ranch in 1997 (PA #96-039, adopted by Dublin City Council Resolution No. 140-97). A Mitigated Negative Declaration was subsequently approved for PI anning Area F of Dublin Ranch in 2000 (SCH # 99112040, PA #98-068, adopted by Dublin City Council Resolution No. 34-00 on February 15, 2000. Both documents were also used in the preparation of this Initial Study and are incorporated herein by reference. ' Mitigation measures included in the Eastern Dublin EIR and the Mitigated Negative Declaration approved in 2000 for Planning Area F continue to apply to the proposed . Project. As part of the certification of the EIR and approval of the Eastern DUblin Specific Plan and General Plan Amendment, the Dublin City Council adopted a Statement of Overriding Considerations for the following impacts: cumulative traffic, extension of certain community facilities (natural gas, electric and telephone service), regional air ' quality, noise and visual, and other impacts identified in Resolution 53-93, dated May 10, 1993 and incorporated herein by reference. Copies of these previous environmental documents are available for review at the Dublin Planning Department during normal business hours. The Project is consistent with the residential, public/semi public, open space and park land use designations of the General Plan and Eastern Dublin Specific Plan. The purpose of the proposed amendments to these plans is to reconfigure the uses within the Amendment Area. The primary result of the Project will be to reduce the amount of potential residential uses across the Amendment Area by approximately 136 units, and increase the amount of Community Park from 52 acres to 65.9 acres. All of the Amendment Area has been the subject of prior CEQA reviews, initially through the 1993 Eastern Dublin EIR, a program-level review of the potential urbanization of Eastern Dublin. Numerous mitigation measures were adopted with the Eastern Dublin general plan and specific plan approvals on May 10, 1993. All of the mitigation measures continue to apply, as appropriate, to implementing projects, including this Project. For the significant and unavoidable impacts, the City adopted a Statement of Overriding City of Dublin Page 28 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 Considerations. (See Resolution 53-93). Pursuant to the recent Communities for a Better Environment case, approval of the Project would require that the City reweigh the identified unavoidable impacts and adopt a new Statement of Overriding Considerations. The Project site was later reviewed in connection with approval of two separate land use revisions and adoption of a PD reZoning and Stage 1 Development Plans. The Dublin Ranch Area F portion of the Project was reviewed in a subsequent Mitigated Negative Declaration (MND). The MND tiered from the Eastern Dublin EIR, and identified additional potentially significant impacts and mitigation measures. Ail of the adopted mitigation measures continue to apply to the Project. The Dublin Ranch Area B and E portions of the Project were reviewed in a subsequent Negative Declaration (ND). No additional significant impacts were identified for these areas and no additional mitigation measures beyond those previously adopted. The following discussions track the environmental checklist above. Where possible, the discussion describes the prior relevant analyses and the prior adopted mitigation measures. The discussions are summary only; the prior EIR, MND and ND should be consulted for full discussion of related impacts and mitigations. The discussions also examine whether the reconfiguration of land uses will have any new or more severe significant impacts that would require preparation of a subsequent EIR, MND or ND pursuant to CEQA Guidelines section 15162. Because the Project does not propose new or different development, i.e., the type and extent of land uses is similar to those assumed in the previous reviews, most impacts are unchanged for the Project. The Project also includes a net reduction in the number of dwelling units across the Amendment Area, therefore, some impacts could actually be reduced compared to the existing approvals. Finally, many of the prior impacts related to biology, soils, drainage and other similar terrain-related impacts no longer apply to the Development Area since this area has been mass graded pursuant to USACE and DFG permits. City of Dublin Page 29 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 Attachment to Initial Study Discussion of Checklist Legend PS: Potentially Significant LS/M: Less Than Significant After Mitigation LS: Less Than Significant Impact NI: NO Impact 1. Aesthetics Environmental Setting .The Project area (comprised.of portions of Area F, B and E) is vacant and consists of gently rolling to relatively steep hillsides. The Eastern Dublin EIR classifies the project site as "valley grasslands," which are located on the areas near 1-580 in the south and southwest portion of Eastern Dublin. Where agricultural activity, including grazing, has historically taken place (such as within the Project area), the visual image of lands is formed by patterns of the soil that have been furrowed. The Eastern Dublin EIR identified the following impacts to visual resources and aesthetics applicable to this Project: · IM 3.8/A: Standardized "tract" development, whereby generic subdivision design could ~.- obscure existing natural features, such as landforms, vegetation and watercourses. -: · IM 3.8/B, C, and D: Alteration of the rural/open space visual character of the area whereby new development allowed under the Specific Plan and General Plan Amendment would change the visual open space area of the Project area, including hillsides. · IM 3.8/F: alteration of the visual character of the flatlands, whereby future urban development on the flatland portion of the Project site would alter views of valley grasses and agricultural fields. The Eastern Dublin EIR contains a number of Mitigation Measures that are applicable to this project to assist in reducing aesthetic impacts to a less-than-significant level, including Mitigation Measures 3.8/1.0 through 8.1. The 1997 Negative Declaration for Planning Areas B-E did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR. The 2000 Mitigated Negative Declaration for Planning Area F identified supplemental Mitigation Measure 1 that required pole mounted streetlights to be equipped with cut-off lenses or directed downward to minimize spill over of lights. Project Impacts and Mitigation Measures a) Have a substantial adverse impact on a scenic vista? LS. Approval and construction of the proposed project would convert existing vacant, former agricultural fields to urban uses, City of Dublin Page 30 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 including residential and similar uses. This potential impact was addressed in the Eastern Dublin EIR (Impact IM 3.8/C, Obscuring of Distinctive Natural Features) and it was determined that no measures would reduce this impact to a less-than-significant level. Other mitigation measures (3.8/4.0 through 4.5, 5.0 and 5.1) have been included in the Eastern Dublin EIR to reduce impacts to hillside development. The EIR concluded this impact would be a potentially significant irreversible change and a Statement of Overriding Considerations was. b) Substantially damage scenic resources, including state scenic highway? NI. The project site is not located adjacent to a state designated scenic highway. c) Substantially degrade existing visual character or the quality of the site? LS. This impact was addressed in the Eastern Dublin EIR and a Statement of Overriding Considerations. d) Create light or glare? LS. As addressed in the 2000 MND, construction of the proposed project would increase the amount of light and glare due to new street lighting and building security lighting. In some instances, the additional lighting could result in negative aesthetic impacts through the "spill over" of unwanted lighting onto adjacent properties, parks and other areas that are not intended to be lighted. Overall, no impacts to visual resources not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 2. Agricultural ResoUrces Environmental Setting According to information contained in the Phase One Hazardous Materials study prepared by Berlogar Geotechnical Consultants for the site, the property has been used exclusively for farming and cattle grazing for the past 40 years, although it is currently fallow. The Eastern Dublin EIR notes that the site is charaCterized by soils of locally important farmland, although not of prime or unique farmland. Based on information contained in the Eastern Dublin EIR (Figure 3. l-C), no portion of the Project Area is encumbered with a Williamson Act Land Conservation Agreement contract. The Eastern Dublin EIR identified the folloWing impacts with regard to agricultural resources: · IM 3. l/C: Discontinuation of agricultural uses, which was a less-than-significant impact due to the high percentage of Williamson Act contracts that were either non-renewed or cancelled. · IM 3. l/D: Loss of farmlands of local importance, which was identified as a less-than- significant since no prime agricultural soils were identified on the Project site. No mitigation measures were contained in the Eastern Dublin EIR, since no potentially significant impacts were identified. City of Dublin Page 31 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 The 1997 Negative Declaration for Planning Areas B-E and the Mitigated Negative Declaration for PA F did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to agricultural resources. Project Impacts and Mitigation Measures a-c) Convert Prime Farmland, conflict with agricultural zoning or conYert prime farmIand to a non-agricultural use? LS. Although the site has historically been used for agricultural crop production, the underlying soil is not considered primary agricultural soil and no Williamson Act Land Conservation Agreement exists on the project site. The Eastern Dublin EIR found that discontinuance of agricultural operations is an insignificant impact based on the large number of non-renewal notices being filed on Williamson Act Agreements within the Eastern Dublin area (Impact 3. l/C). Similarly, loss of farmland of local importance, such as the project site, were considered a less-than- significant impact due to the fact that on-site soils are not prime 'agricultural soils (Impact 3.l/D). Overall, no impacts to agricultural lands and resources not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E. or the 2000 MND for PA F are expected to occur as a result of this Project. 3. Air Quality ' Environmental Setting Dublin is located in the Tri-Valley Air Basin. Within the Basin, state and federal standards for nitrogen dioxide, sulfur dioxide and lead are met. Standards for other airborne pollutants, including ozone, carbon monoxide and suspended particulate matter (PM-10) are not met in at least a portion of the Basin. The Eastern Dublin EIR identified the following impacts with regard to air quality: · IM 3.1 l/A: Dust deposition soiling nuisance from construction activities, which was identified as a potentially significant cumulative impact. · IM 3.11/B: Air emission from construction equipment, which was identified as a potentially significant impact. · IM 3.11/C: Air quality impacts related to mobile emissions of reactive organic gasses and nitrogen monoxide, which was identified as a potentially cumulative significant impact. · IM 3.11/D: Mobile source emission of carbon monoxide, which was identified as a less- than-significant impact. · IM 3.11/E: Stationary source emissions from HVAC and other sources, which was a potentially significant cumulative impact. City of Dublin Page 32 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 'Mitigation Measures 3.11/1.0 through 13.0 were included in the Eastern Dublin EIR to assist in reducing long- and short-term air quality impacts. Impacts related to emission from construction vehicles~ mObile source emission of reactive Organic gasses and nitrogen dioxide and stationary source emissions were identified as significant and unavoidable and a Statement of Overriding Considerations were adopted by the City of Dublin for these impacts. The 1997 Negative Declaration for Planning Areas B-E and 2000 Mitigated Negative Declaration for PA F did not identify new or supplemental impacts or mitigation measures from the EaStern Dublin EIR related to air qualityl Project Impacts and Mitigation Measures a) Would the project conflict or obstruct implementation of an air quality plan? LS. 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 have been included in Dublin's planned growth as part of Eastem Dublin Specific Plan/General Plan. b) Would the project violate any air quality standards? LS. Short-term construction imPacts related to implementation of the project, including grading and excavation, could result in exceedances of air quality standards established by the Bay Area Air Quality Management District (Eastern Dublin EIR, Impacts 3.11/A and B). Adherence to Mitigation Measure 3.11/1.0 and Mitigation Measure 3.11/2.0 contained in the Eastern Dublin EIR will reduce short-term air 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 Eastern Dublin EIR concludes that potential air quality impacts related to construction equipment could not be mitigated to a less-than-significant impact and a Statement of Overriding Considerations was adopted for this impact. If this project were to be approved, a new Statement of Overriding Considerations would need to be adopted by the City of Dublin. Similarly, potential air quality impacts related to mobile source emissions of Reactive Organic Gasses and Nitrogen Oxide, both precursor indicators of smog, and stationary source emissions were found to exceed regional air quality standards even with mitigation measures, and were included in the Statement of Overriding Considerations (Eastern Dublin EIR Impacts 3.11/C and E). If this project were to be approved, a new Statement of Overriding Considerations would need to be adopted by the City of Dublin. c) Would the project result in cum~datively considerable air pollutants? LS. The Eastern Dublin EIR identifies Mobile Source Emissions and Stationary Source Emissions as significant irreversible impacts. Generally such impacts are based on vehicular emission from future traffic within the sub-region as well as stationary sources. A Statement of Overriding Considerations was adopted for long-term impacts. If this project were to be approved, a Statement of Overriding Considerations would need to be adopted by the City of Dublin. d, e) Expose sensitive receptors to significant pollutant concentrations or create objectionable odors? LS. The majority of land uses proposed for the Project Area include residential land uses, which are not considered as sensitive .receptors. As noted in the 2000 MND, the Project includes both an elementary school and middle school, Which could be considered City of Dublin Page 33 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-O37 sensitive receptors; however no additional impacts were identified beyond the Eastern Dublin EIR. Overall, no impacts to air quality not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 4. Biological Resources Environmental Setting The Eastern Dublin EIR indicates that the Project Area is dominated by non-native grassland and dryland-farmed (grain crops) habitats. Fields are typically cropped at various seasonal and annual rotations followed by fallow years at a rate of one in every five years. Crops are not irrigated. Biological analyses and wetland delineations were conducted for the Eastern Dublin EIR as well as the MND and ND, describing both habitat and species present in the Project area, and information on wetland resources. As noted earlier, the Development Area portion of the Project site has been mass graded pursuant to USACE and DFC permits. The graded area included ponds with habitat value and species as identified in the prior CEQA reviews; however, species such as California red-legged frog and California Tiger Salamander were relocated to offsite mitigation areas, again, in conformance will applicable permits and requirements. A copy of the Corps permit is appended to this Initial Study. · ~.;'~.. Plants :' - Based on the history of cultivation of the Project Area, most of the 23 special-status plant species identified as potentially occurring in the project area are not expected to be present. Previous " agricultural activities, including livestock grazing and crop production, have deglmded potential habitat for these species, and existing predominant plant species include invasive forbs and grasses indicative of disturbed habitats. Although neither the Congdon's tarplant (Hemizonia parryi ssp. congdonii) nor San Joaquin spearscale (Atriplex joaquiniana) has been observed in the Project Area, Congdon's tarplant has been observed on Area H to the south, and San Joaquin spearscale has been observed on a nearby parcel to the southeast. Animals The Eastern Dublin EIR, the MND and the ND provide background information on the potential for special-status and sensitive animal species that could potentially occur in the Project area. With the permitted grading on the Project site and related offsite mitigation and species relocation, many of the species are no longer expected to occur in the Project area Mitigation measures addressing these species have been incorporated into the wetland fill permit issued by the U.S. Army Corps of Engineers on May 23, 2003. In accordance with the permit conditions, red-legged frogs and tiger salamanders have been relocated to an off-site mitigation area. Wetlands Jurisdictional wetlands were addressed in the Project area in the Eastern Dublin EIR, MND and ND. As noted above, a wetland fill permit was issued by the USACE and the wetlands have been filled City of Dublin Page 34 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 The Eastern Dublin EIR identified a number of potentially significant impacts to biological resources, including IM 3.7/A (direct habitat loss), IM 3.7/B (indirect impacts of vegetation removal), IM 3.7/C (loss or degradation of botanically sensitive habitat), IM 3.7/D (impacts to San Joaquin kit fox), IM 3.7/E (impacts to bald eagle, peregrine falcon and Alameda whipsnake), IM 3.7/F (impacts to red-legged frog), IM 3.7/G (California tiger salamander), IM 3.7/H (impacts to western pond turtle), IM 3.7/I (impacts tri-colored blackbirds), IM 3.7/J (destruction of Golden eagle nesting sites, IM 3.7/K (elimination of Golden eagle foraging sites), IM3.7/L (Golden eagle and other raptor electrocution), IM 3.7/M impacts to burrowing owl), IM 3.7/N (impacts to American badger), IM 3.7/0 (impacts to prairie falcon, northern harrier and black- shouldered kite), IM 3.7/P (impacts to sharp-shinned hawk and Cooper's hawk), IM 3.7 Q (impacts to short-eared owl), IM 3.7/R impacts to California horned lizard), IM 3.7/S (impacts to special-status invertebrates). A number of mitigation measures are included in the Eastern Dublin EIR to reduce all of the above impacts to less-than-significant levels, except for the loss of botanically sensitive habitat. These are Mitigation Measures 3/7/1.0 to 28.0. These mitigation measures continue to apply to this project. The 1997 Negative Declaration for Planning Areas B-E did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to biological resources. The 2000 Mitigated Negative Declaration for Planning Area F contained Supplemental Mitigation Measures 2 and 3 to protect special-status species and wetlands in this Planning Area. Project Impacts and Mitigation Measures a) Have a substantial adverse impact on a candidate, sensitive, or special-status species? LS. Development of the Project area would have impacts on the California red-legged frog and California tiger salamander that are less than significant with mitigation incorporation. This development could potentially have impacts on the Congdon's tarplant, San Joaquin spearscale, Burrowing Owl, White-tailed Kite (and other tree-nesting raptors), and American badger that are less than significant with mitigation incorporation. Site clearing and grading could result in direct loss of individuals of Congdon's tarplant and San Joaquin spearscale if these species are present on the site. Clearing and grading could result in the loss of individual tiger salamanders and their estivation habitat, and filling of the stock pond would result in the boss of 0.7 acres of red-legged frog and tiger salamander breeding habitat and could potentially result in the loss of individuals. Clearing and grading could result in the loss of individual burrowing owls, their occupied burrows, and occupied Burrowing Owl habitat; and individual American badgers. Tree removal or indirect disturbance during the breeding season could result in the loss of eggs, young, or active nests of the White-tailed Kite and other tree-nesting raptors. In accordance with the approval conditions of the USACE wetland fill permit (dated May 23, 2003); U.S.F.&W.S. Biological Option (dated July 1, 2002); RWQCB Water Quality Certification Order (dated April 22, 2003); and CDF&G 1603 Lake and Streambed Alteration Agreement (dated June 5, 2003) mitigation measures addressing impacts on candidate, sensitive or special status species have already been implemented. Based on implementation of these measures, the above noted species impacts are no longer considered to be applicable to this Project. City of Dublin Page 35 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-O37 As part of the project, project builders and developers have obtained necessary permits from 'apprOPriate state and federal environmental permits prior to grading operations, including but not limited to permits from the United States Army Corps of Engineers, U.S. Fish and Wildlife Service, California Department of Fish and .Game and Regional Water Quality Control Board. b, c) Have a substantial adverse impact on riparian habitat or federally protected wetlands? LS. Approximately 1.47 acres of U.S. Army Corps of Engineers (USACE)jurisdictional habitats (including 0.48 acres of wetlands), based on the draft jurisdictional delineation and verified by the Corps, and 1.6 acres of California Department of Fish and Game (CDFG) jurisdictional habitats, have been identified within the Project Area and required mitigation, as established by the appropriate agency, has been provided. In accordance with the approval conditions of the USACE wetland fill permit (dated May 23, 2003); U.S.F.&W.S. Biological Option (dated July 1, 2002); RWQCB Water Quality Certification Order (dated April 22, 2003); and CDF&G 1603 Lake and Streambed Alteration Agreement (dated June 5, 2003), mitigation measures addressing impacts on candidate, sensitive or special status species have been or currently are being implemented. As part of the project, project builders and developers have obtained necessary permits from appropriate state and federal environmental permits prior to mass grading operations, including but not limited to permits from the United States Army Corps of Engineers, U.S. Fish and Wildlife Service, California Department of Fish and Game and Regional Water Quality Control Board. d) Interfere with movement of native fish or WiMl~fe species? NI. Two small intermittefit .... drainage channels formerly traversed the site, but have been filled as part of Corps- and ' CDFG-permitted mass grading operations n the Project area. However, no significant wildlife movement occurs on or across the site, and therefore, development is not expected to preclude any significant wildlife movements. e, f) Conflict with local policies or ordinances protecting biological resources or any adopted Habitat Conservation Plans or Natural Community Conservation Plans? NI. No significant stands of trees are present on the site, and there are no impacts with regard to local tree preservation ordinances or policies. The site is not located within the boundaries of any Habitat Conservation Plans. Overall, no impacts to biological resources not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 5. Cultural Resources Environmental Setting The Eastern Dublin area was surveyed in 1988 as part of the Eastern Dublin Specific Plan and associated EIR. Several potentially significant archeological resources were identified in the project area and the Eastern Dublin EIR mandated additional project-level archeological surveys. City of Dublin Page 36 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 In May, 1999, Holman and Associates resurveyed the site by means of a mechanical backhoe ..... Several battered petrified wood fragments were discovered, however, later laboratory investigation indicated the fragments likely resulted from natural tumbling or damage from farm equipment. In .summary, no potentially significant prehistoric archeological materials or indicators were found on the property during the study. The Eastern Dublin EIR identified the following impacts with regard to cultural resources: · IM 3.9/A: Disruption or destruction of identified prehistoric resources, which was identified as a potentially significant impact. · IM 3.9/B: Disruption or destruction of unidentified pre-historic resources, which was identified as a potentially significant impact. · IM 3.9/C: Disruption or destruction of identified historic resources, which was identified as a potentially significant impact. · IM 3.9/D: Disruption or destruction of unidentified historic resources, which was identified as a potentially significant impact. Mitigation Measures 3.9/1.0 to 12.0 were adopted to reduce impacts to historic and pre-historic resources to a less-than-significant level. The 1997 Negative Declaration for Planning Areas B-E did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to cultural resources. The Mitigated Negative Declaration for Planning Area F (2000) identified Supplemental Mitigation Measure 4, intended to protect unrecorded cultural resources. Project Impacts and Mitigation Measures a) Cause substantial adverse change to significant historic resources? NI. The site is vacant and no historic resources have been identified on the site. Therefore, the possibility of encountering historic resources is considered remote and no impact is expected. b, c) Cause a substantial adverse impact or destruction to archeological or paleontological resources? LS. The 2000 MND identified a remote but potentially significant possibility that construction activities, including site grading, trenching and excavation may uncover significant paleontological resources. Mitigation Measures 3.9/5.0 and 6.0, cOntained in the Eastern Dublin EIR were adopted to reduce this impact to a less-than-significant level and will be implemented with Project development. d) Disturb any human resources? LS. A remote possibility exists that human resources could be uncovered on the site during construction activities. Mitigation Measures 3.9 5.0 and 6.0 contained in the eastern Dublin EIR were adopted to reduce such impacts to a level of less- than-significance. Overall, no impacts to cultural resources not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. City of Dublin Page 37 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 6. Geology and Soils (This section is based on a preliminary geotechnical reports cited in the 1997 ND and the 2000. The reports are on file in the City of Dublin Planning Department) Environmental Setting This section of the Initial Study addresses seismic safety issues, topography and landforml drainage and erosion and potential impacts .to localized soil types. SeiSmic The Project Area is a part of the San Francisco Bay area, one of the most seismically active regions in nation. The Eastern Dublin EIR notes the presence of several nearby significant faults, including the Calaveras Fault, Greenville Fault, Hayward Fault, and San Andreas Fault. The likelihood of a major seismic event on one or more of these faults within the near future is believed to be high. The project site is not part of a Special Studies ZOne for faults as identified by the State of California, however, previous geotechnical investigations of the area show inferred faults along the northerly portion of the Project Area (identified as the "Mocho Fault"). , The Mocho Fault was mapped by the California Division of Mines and Geology in 1974 and was ':later evaluated as part of the Alquist-Priolo Special Studies Zone. As part of this evaluation it was concluded that the existence of the Mocho Fault was questionable and geomorphic features could be caused by differential erosion. 'A SecO~d thrust fault System has been inferred in the Coast Ranges of the Bay Area that may be seisimi~ally active. A belt of faults and folds has been mapped in sedimentary rocks south of Mount Diablo, including one identified as the "leading edge-blind thrust, Mount Diablo Domain," Further inVeStigation of this inferred fault by Berlogar Geologic Consultants has concluded that the risk of ground rupture from this inferred fault is low within the Project Area. Site Soils Site soils are characterized as c011uvium, which is highly expansive and consists of dark gray, very stiff to hard silty clay. Artificial fill has been placed on the site to create a stock pond (see below), with the fill material consisting of a stiff, light gray-brown, clayey silt. Landform and Topo grqP hy The Project Area is part of a broad nOrth-South trending plain known as the Livermore-Amador Valley. Existing elevations on the site range from approximately 450 to 500 feet above sea level. Since the prior CEQA reviews, portions of the Project site have been graded in accordance with USACE and other permits and requirements. The grading eliminated ponds on the Project site, subject to offsite mitigation. The preliminary geOtechnical report indicates a history of landslides on the site. Five slide areas have been identified, all of Which are relatively shallow, on the order of 5 to 10 feet each. LandSlides have occurred within deposits of highly expansive colluvium soils. Drainage City of Dublin page :38 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 The permitted grading eliminated a number of small, unnamed north-sOuth trending intermittent streams that were described in the prior CEQA reviews. Drainage patterns generally follow a north-to -south direction, consistent with the overall topography of the East Dublin area. The Eastern Dublin EIR identified the following impacts with regard to soil and geological resources as applicable to this Project: · IM 3.6/A: Ground fault rupture, which was identified as a less-than-significant impact. · IM 3.6/B: Primary impacts of groundshaking due to earthquake activity, which was identified as a potentially significant impact. · IM 3.6/C: Secondary impacts ofgroundshaking due to earthquake activity, which was identified as a potentially significant impact. · IM 3.6/D: Substantial alteration to site landforms, which was identified as a potentially significant impact. · IM 3.6/F: Impacts to grotmdwater resources, which would be a potentially significant impact. · IM 3.6/G: Impacts to groundwater resources due to irrigation, which would be a potentially significant impact. · IM 3.6/H: Shrink and swell impacts related to expansive soils, which would be a potentially significant impact. · IM 3.6/K: & L: Construction and long-term erosion and sedimentation, which would be potentially significant impacts. Mitigation measures contained in the Eastern Dublin EIR were adopted to reduce the above imPacts to less-than-significant levels except IM 3.6/B regarding groUndshaking, which was significant and unavoidable. The 1997 Negative Declaration for Planning Areas B-E and the 2000 PA F MND did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to soils or geotechnical issues. Project Impacts and Mitigation Measures a) Expose people or structures to potential substantial adverse impacts, including loss, injury or death related to ground rupture, seismic ground shaking, ground failure, or landslides? LS. The Project site is subject to ground shaking caused by a number of regional faults identified above. Under moderate to severe seismic events which are probable in the Bay Area over the next 30 years, buildings, utilities and other improvements constructed in the Project Area would be subject to damage caused by ground shaking. Since the Project Area is not located within an Alquist-Priolo Earthquake Safety Zone and the potential for ground rupture is anticipated to be minimal. Mitigation Measures 3.6/1.0 City of Dublin Page 39 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 through 8.0 contained in the Eastern Dublin EIR were.adopted to ensure that new : structures built within the Project Area will comply with generally recognized seismic safety standards so that ground shaking impacts would be reduced to a level of less-than- significant. Portions of Project area are hilly and have a history of landslides. As anticipated in the prior MND, the site has been graded and re-contoured to accommodate building pads, roads, parking areas and other development areas and to improve and control site drainage. Mitigation Measures 3.6/17.0-26.0 were adopted as part of the Eastern Dublin Plan EIR to reduce potential impacts to slopes to a level of less-than-significant. These' mitigation measures require the preparation of site-specific soils and geotechnical reports, minimizing grading on steep slopes and adherence to Uniform Building Code and other City requirements for grading. b) Is the site subject to substantial erosion and/or the loss of topsoil? LS. The Eastern Dublin EIR notes that an impact of constructing all of the land uses identified in the Eastern Dublin Specific Plan/General Plan would be an increase of erosion and sedimentation caused by grading activities. Consistent with adopted Mitigation Measures 3.6/27.0 and 3.6/28.0, conditions of approval require the Project to prepare and implement interim erosion plans as part of grading permits. With adherence to these mitigation measures, potential erosion impacts will be reduced to a less-than-significant level. c-d) Is the site located on soil that is unstable or expansive or result in potential lateral spreading, liquefaction, landslide or collapxe? LS. Portions of the Eastern Dublin Specific Plan/General Plan, including the Project Area, are subject to soil types with high shrink- :~ swell potential. Mitigation Measures 3.6/14.0 through 16.0 were adopted to reduce potential shrink-swell impacts to a level of less-than-significance by requiring appropriate structural foundations and other techniques to overcome shrink-swell effects. No additional mitigation measures are required. e) Have soils incapable of supporting on-site septic tanks if sewers are not available? NI. The project developer has indicated that each dwelling would be connected to a sanitary sewer provided by Dublin San Ramon Services District. Therefore, no impact is anticipated with regard to septic tanks. Overall, no impacts tO soils and geology not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 7. Hazards and Hazardous Materials Environmental Setting The site has been partially graded; the remaining area is primarily open grasslands and currently contains no structures. Phase I and Phase II hazardous materials studies were completed for the site by Berlogar Geotechnical Consultants in 1996 and 1997 with the finding that no hazardous materials has been identified on the site. The site has not been listed as containing a hazardous site, hazardous material generator or transporter or having known underground storage tanks. City of Dublin Page 40 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 The Eastern Dublin EIR identified IM 3.4/E (exposure to wildfire hazards) as a potentially significant impact, which could be reduced to a less-than-significant level through adherence to Mitigation Measures 3.4/6.0 trough 11.0. ~ The 1997 Negative Declaration for Planning Areas B-E and PA F MND (2000) did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to hazards or hazardous materials. Project Impacts and Mitigation Measures a-c) Create a significant hazard through transport of hazardous materials or release or emission of hazardous materials? LS. Proposed uses of the site would include residential, schools, parks and open spaces. There is no change from the 1997 MN and 2000 MND conclusions that only minor and less-than-significant quantities of potentially hazardous materials would be associated with such uses. Materials would include normal and customary such as lawn chemicals, household solvents and similar items. d) Is the site listed as a hazardous materials site? NI. A previously completed Phase II hazardous materials analysis indicates that the site is free of hazardous materials. No impacts are therefore anticipated. e, f) Is the site located within an airport land use plan ora public airport or private airstrip? LS. The Project Area is located northwesterly of the Livermore Municipal Airport. The City of Dublin referred the Specific Plan/General Plan Amendment applications for Planning Areas F-H to the Alameda County Airport Land Use Commission (ALUC). At the ALUC meeting on April 14, 1999, the Commission noted that Planning Areas F,G & H all lie outside of the referral area for Livermore Municipal Airport and the ALUC has no jurisdiction over land uses within the Project Area. The rest of the Project area is similarly outside of the referral area. g) Interference with an emergency evacuation plan? NI. Adequate emergency access has been provided via the proposed collector street system to and from the site to the satisfaction of the Alameda County Fire Department. Due to the provision of adequate access, there would be no impact with regard to emergency evacuation plans. h) Expose people and structures to a significant risk of loss, injury or death involving wiMland fires or where residences are intermixed with wiMlands? LS. The Project Area is currently a vacant field and is subject to grassland fires. However, the long-term plan for the area is for urbanization. Although parks and open spaces would be part of the long-term land use plans, such areas would generally be irrigated. Development of the area would include adding new water lines for firefighting purposes as well as new fire stations and personnel. Overall, no impacts to hazards and hazardous materials not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 8, Hydrology and Water Quality City of Dublin Page 41 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 ("" Environmental Setting Portions of the Project area were formerly hilly with two intermittent creeks flowing through. The area was recently graded and the drainages filled pursuant to appropriate permits. Based on information contained in the Eastern Du~bl. in ~EIR, none of the Project Area is located within a 100-year flood plain as identified on the applicable Flood Insurance Rate Map published by the Federal Emergency Management Agency. See earlier discussion in Section V, Geology, regarding the history of landslides within Planning Area F. The Eastern Dublin EIR identified the following impacts with regard to hydrology and water quality as applicable to this Project: · IM 3.5/Y: Potential flooding, which was identified as a less-than-significant impact. · IM 3.5/Z: Reduced groundwater recharge, which was identified as a potentially significant impact. · IM 3.5/AA: Non-point sources of pollution, which was identified as a potentially significant impact. Mitigation Measures 3.5/44.0 to 55.0 were included in the Eastern Dublin EIR to reduce the above impacts to a less-than-significant level The 1997 Negative Declaration for Planning Areas B-E did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to hydrology and water quality: The Mitigated Negative Declaration for Dublin Ranch PA F contained Supplemental Mitigation Measures 5 and 6 to ensure that potential surface water quality and flooding impacts are reduced to a less-than-significant level. Project Impacts and Mitigation Measures a) Violate any water quality standards or waste discharge requirements? LS. Construction of improvements anticipated within the Project Area plan would necessitate grading and overcovering of the soil in order to construct roadways, building pads, utility connections and similar features. The amount of grading is not known at this time, however, proposed grading is anticipated to increase the possibility of soil erosion into creeks and other bodies of water, on and off the project site. As noted in the 2000 MND, standard City of Dublin development conditions of approval require erosion control plans and preparation of a Stormwater Pollution Prevention Plan. No additional water quality impacts are anticipated beyond those previously described. b) Substantially deplete groundwater recharge areas or lowering of water table? LS. Although currently vacant sites would be converted to urban uses, this impact has been addressed in the Eastern Dublin EIR (Impact 3.5) and Mitigation Measures 3.5/49.0 and ff---, 50.0, so no further analysis is reqUired. City of Dublin Page 42 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-O37 c) Substantially alter drainage patterns, including streambed courses such that substantial siltation or erosion wouM occur? LS. The Eastern Dublin EIR acknowledges that implementation of the Eastern Dublin Specific Plan would change existing natural drainage patterns. PropOsed changes would include grading and re-contouring much of the site and filling existing intermittent streams and the existing stock pond and replacing these with underground pipes and culverts to accommodate storm water runoff, some of which activity has already occurred with appropriate permits. Stormwater runoff would eventually flow to the Alameda County Flood Control District and Water Conservation District G-3 facility immediately north of the 1-580 freeway. Two areas where natural drainage is proposed to be recreated are a revegtated stream/open space corridor on the west side of Grafton Street adjacent to the middle school site and an extension of the existing stream corridor on the west side of Fallen Road. Based on preliminary hydrological information for the Project Area prepared by the applicant's engineer, adequate downstream facilities currently exist or will be constructed to accommodate anticipated storm water runoff from the fully improved Project Area. Approval of the proposed project and implementation of construction projects pursuant to the amended Specific Plan/General Plan and other entitlements would increase stormwater runoff from the site and, at the same time, increase erosion off of the site. The City of Dublin requires individual project developers within the Project Area to prepare and implement Stormwater Pollution Prevention Programs to control erosion from the site for both construction and post construction periods. Approvals of such SWPPPs by the City of Dublin and State Water Resources Control Board are required for individual developments greater than one acre. d) Substantially alter drainage patterns or result in flooding, either on or off the project site? LS. Approval of the proposed project and construction of neW housing units and other improvements would change drainage patterns within the Project Area. Existing natural streams, swales and other surface drainage flows would be altered due to anticipated site grading, some of which has already Occurred with appropriate permits. Drainage would be routed through newly constructed underground pipes, culverts and similar facilities A master drainage plan has been submitted by the applicant, indicating that storm drain improvements would be constructed to connect with existing and planned drainage improvements within the Eastern Dublin area. e) Create stormwater runoff that would exceed the capacity of drainage systems or add substantial amounts of polluted runoff?. LS. Construction of on-site improvements, as well as new improvements upstream of the Project Area, is anticipated to lead to greater quantities of storm water runoff. As noted in the 2000 MND, standard City of Dublin development conditions of approval require erosion control plans and preparation of a Stormwater Pollution Prevention Plan f) Substantially degrade water quality? LS. Refer to the analysis under "a," ~bove. g) Place housing within a lO0-year flood hazard area as mapped by a Flood Insurance Rate Map? NI. None of the Project Area is located within a 100-year flood plan as mapped by FEMA and no new dwellings would be located in a flood hazard area. There would therefore be no impact in regard to flooding hazards. City of Dublin Page 4:3 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 h, i) Place within a lO0-year flood hazard boundary structures that impeded or redirect flood flow, including dam failures? NI. As noted in the response to "g," above, none of the Project Area is located within a flood hazard area as defined by the Federal Emergency Management Agency. Proposed drainage on and off the project site would transport stormwater runoff into approved City or regional drainage facilities for apPropriate disposal, so there would be no impact with regard to anticipated drainage facilities.. No impact is anticipated related to dam or levee break, since the existing stock pond within the Project Area has been removed as noted above. j) Result in inundation by seiche, tsunami or mudflows? LS. The site is not located near a major body of water that could result in a seiche. The risk of potential mudflow is considered low based on the Berlogar Geotechnical report. Mitigation Measures adopted as part of the Eastern Dublin EIR will reduce potential impacts of natural and engineered slope stability, and erosion and sedimentation impacts to a level of less-than-significance. These mitigation measure include MM's 3.6/17-28. Briefly, these mitigation measures require site-specific geotechnical analyses of each proposed development, appropriate siting of new construction, use of appropriate engineered fill with proper compaction and limiting the slope of grading. Overall, no impacts to hydrology and water quality not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expeCted to occur as a result of this Project. 9. Land Use and Planning Environmental Setting The Project proposes to reorient some uses and improvements on the Project site; however, the nature and extent of development will not substantially change. Density overall is proposed at lower levels than existing approvals, and no new development areas are proposed compared to those assumed in prior reviews. The Eastern Dublin EIR identified the following impacts with regard to land use as appliCable to this Project: · IM 3. l/A: Substantial alteration to existing land use, which was identified as a less-than- significant impact. · IM 3. I/B: On-site land use impacts, which was identified as a less-than-significant impact. The 1997 Negative Declaration fOr Planning Areas B-E and the 2000 MND for PA F did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to land use. City of Dublin Page 44 I.nitial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 Project Impacts and Mitigation Measures a) Physically divide an established community? NI. The project is vacant and has been ~ planned for uses similar to the Project since the original adoption of the Eastern Dublin Specific Plan/General Plan in 1993. Therefore there would be no disruption of any establiShed community. b) Conflict with any applicable land use plan, policy or regulation? LS. The proposed project would be consistent with goals and policies contained in the Eastern Dublin Specific Plan/ General Plan. The extent of the proposed amendment includes relocating various land uses within the Project Area to respond to changed real estate market conditions, land use revisions requested by the City to create additional public/semi-public sites and DUSD school site selection requirements for the middle school. The proposed land use changes to the Project Area would result in a decrease of approximately 136 dwellings over the Amendment Area. c) Conflict with a habitat conservation plan or natural community conservation plan? NI. No such plan has been adopted within the Eastern Dublin Specific Plan/General Plan area. There would therefore be no impact to a habitat conservation plan or natural community conservation plan for the Project Area. Overall,' no impacts to land use and planning not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E or the 2000 MND for PA F are expected to occur as a result of this Project. 10. Mineral Resources '~ Environmental Setting The Project area contains no known mineral resources. Project Impacts and Mitigation Measures a, b) Result in the loss of availability of regionally or locally significant mineral resources? NI. The Eastern Dublin EIR does not indicate that significant deposits of minerals exist on the site, so no impacts would occur. Overall, no impacts to mineral resources not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 11. Noise Environmental Setting Major sources of noise on and adjacent to the project site include distant noise generated by vehicles passing through the Eastern Dublin Planning Area on 1-580, traffic sources on Tassajara Road and from aircraft flyovers Based on Figure 3.10 B contained in the Eastern Dublin EIR, minor portions of Planning Area F would be subject to significant long-term noise exposure, defined as 60 decibels CNEL for City of Dublin Page 45 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 exterior noise.. As noted in the 1997 ND, proposed housing along Fallon Road, Central Parkway and Gleason Road could also be affected. Since major noise sources are from both Tassajara Road and 1-580, construction of permanent buildings and sound walls in adjacent planning areas would reduce exterior noise levels to 60 decibels CNEL or less at the southerly and westerly boundary of the Project Area. The Eastern Dublin EIR identified the following impacts with regard to noise as applicable to this Project: · IM 3.10/A: Exposure of proposed housing to future roadway noise, which was identified as a potentially significant impact. · IM 3.10/C: Exposure of existing and proposed development to airport noise, which would be a less-than-significant impact. · IM 3.10/E: Exposure of existing and proposed residences to construction noise, which would be a potentially significant impact. · IM 3.10/F: Noise conflicts due to adjacency of diverse land uses permitted by Specific Plan policies, which would be a potentially significant impact. Mitigation Measures 3.10/1.0, 3.0, 4.0, 5.0, and 6.0 were adopted to reduce noise impacts to a less-than-significant level, primarily through project specific acoustical analysis to reduce indoor residential noise exposure to 45dB. The 1997 Negative Declaration for Planning Areas B-E and the 2000 MND prepared for Dublin Ranch PA. F did not identify new'or supplemental impacts or mitigation measures from the Eastern Dublin EIR related j;o noise. Project Impacts and Mitigation Measures a, d) Would the project expose persons or generation of noise levels in excess of standards established by the General Plan or other applicable srandard: LS. Construction of future individual development projects within the Project Area would result in short term noise during construction of proposed dwellings, parks and other improvements outlined in the proposal. Mitigation Measures 3.10/4.0 and 5.0 contained in the Eastern Dublin EIR require individual project builders to prepare construction noise management plans to minimize noise as well as adhere to construction hour limitations. Mitigation Measures 3.10/1.0-3.0 require that individual acoustical analysis be prepared as part of individual residential subdivisions and mixed use projects within a 60 decibel or greater CNEL contour. b, e-f) Exposure of peopIe to excessive groundborne vibration or groundborne noise levels? NI No impacts are anticipated for groundborne vibration or noise, since no sources of vibration currently exist within or adjacent to the Project Area, such as heavy industrial facilities or railroads. City of Dublin Page 46 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-O37 c) Substantial permanent increases in permanent in ambient noise levels? LS. The Eastern Dublin EIR addressed exposure of proposed housing to future roadway and construction noise and adopted related mitigation measures. The EIR also discussed ambient noise increases for existing housing due to future roadway noise. No housing exists on the Project site that would be affect by increased ambient noise. Housing in the general area is newer housing built pursuant to prior Dublin Ranch approvals Overall, no impacts to noise not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 12. Population and Housing Environmental Setting The State Department of Finance has determined that Dublin's population was 35,500 as of January 1, 2003. The adopted Eastern Dublin Specific Plan/General Plan anticipates an ultimate population of 12,458 dwelling units in the Eastern Dublin planning area at full buildout of all land uses within the Planning Area. The Project is within the area planned for development. Project Impacts and Mitigation Measures a) Induce substantial population growth in an area, either directly or indirectly? LS. The Project proposes to reorient land uses, but is substantially consistent with the existing, approved Eastern Dublin Specific Plan/General Plan. The proposed amendment to the Eastern Dublin Specific Plan/General Plan would redesignate a portion of the neighborhood east of Grafton (F2) from medium density residential to Iow density residential to be consistent with the current low density residential designated portiOn to the west. The neighborhood west of Grafton (Fl) is to be redesignated from low density to medium density residential. Based upon an average person-per-household occupancy of 2.0 persons per dwelling for Medium Density Residential and 3.2 persons per dwelling for Low Density Residential, approval and implementation of the amendment would result in an ultimate total Project Area population of 2,725 persons at project buildout. This population number is less than the population buildout the same area under the existing Eastern Dublin Specific Plan which was anticipated to have a total poPulation of 2,961 persons. b, c) WouM the project displace substantial numbers of existing housing units or people? NI. The site is vacant. Implementation of the proposed project would therefore displace neither housing units or people. Overall, no impacts to population or housing resources not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 13. Public Services Environmental Setting City of Dublin Page 47 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 · Fire Protection. Fire protection services are handled by the Alameda County Fire Department, which contracts with the City of Dublin for fire suppression, fire prevention, education, inspection services and hazardous material control to the community. · Police Protection: Police and security protection is provided by Alameda County Sheriff Department, which contracts to the City of Dublin for 24-hour security patrols throughout the community in addition to crime prevention, crime suppression and traffic safety. · Schools. The Dublin Unified School District (DUSD) provides educational services to the City of Dublin. · Maintenance. Maintenance of streets, roads and other governmental facilities are the responsibility of the City of Dublin Public Works Department. · Solid Waste Service: Livermore Dublin Disposal Company. The Eastern Dublin EIR identified the following impacts with regard to public services as applicable to this Project: IM 3.4/A (demand for increased police services), IM 3.4/B (police service accessibility), IM 3.4/C (demand for increased fire services), IM 3.4/E (exposure to wildland fire), IM 3.4/F (demand for new classroom space), IM 3.4/G (demand for junior high schools), IM 3.4/H (overcrowding of schools), IM 3.4/0 (increased solid waste production), and IM 3.4/P (impact on solid waste disposal facilities). All of the above were identified as potentially significant impacts. EIR Mitigation Measures were adopted to reduce public service impacts to a less-than-significant level. The 1997 Negative Declaration for Planning Areas B-E and the 2000 MND prepared for Dublin Ranch PA F did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to public services. Environmental Impacts and Mitigation Measures a) Fire protection? LS. Construction of the proposed project would increase demand for fire and emergency services by increasing the amount of permanent population on the site. This impact was previously addressed in the Eastern Dublin EIR, the 1997 ND and the 2000 MND. Features which would be incorporated into specific subdivisions as part of existing City ordinances and development requirements and to assist in reducing impacts would require installation of on-site fire protection measures such as fire sprinklers, installation of new fire hydrants and meeting minimum fire flow requirements contained in the Uniform Building Code and Uniform Fire Code. Developers within the Project Area must also adhere to Mitigation Measures 3.4/6.0-13.0 contained in the Eastern Dublin EIR. These mitigation measures relate to funding new fire facilities in eastern Dublin, ensuring adequate water supplies and pressure for fire suppression, and minimizing wildland fire hazards. City of Dublin Page 48 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 b) Police protection? LS. Incremental increases in the demand for police service could be expected should the Project be approved and future development constructed. Impacts would generally include increases in home burglary and theft. Project developers would also be required to adhere to Mitigation Measures 3.4/1.0-5.0 set forth in Eastern Dublin EIR. These measures deal with establishing funding mechanisms for additional police personnel and facilities and require the inclusion of security provisions into individual development projects. c) Schools? LS. Approval of the proposed the Project and construction of individual residential development projects would increase demand for school facilities. The Eastern Dublin EIR requires project developers to adhere to Mitigation Measures 3.4/13.0-19.0. Since the approval of the Eastern Dublin Specific Plan/General Plan, the property owners of the Dublin Ranch have entered into a mitigation agreement with the Dublin Unified School District to ensure that full mitigation is provided for new development occurring within Dublin Ranch. d) Maintenance of public facilities, including roads? LS. Approval of the project and construction of follow-on development projects would incrementally increase the long-term maintenance demand for rOads and other public facilities. However, such additional maintenance demands will be offset by additional City fees and property tax revenues accruing to the City of Dublin. e) Solid waste generation? LS. Approval of the project and construction of individual development projects under the auspices of an amended Specific Plan/General Plan would incrementally increase generation of solid waste. The Eastern Dublin EIR requires adherence to MitigatiOn Measures 3.4/37.0-40.0. These measures require the preparation of a solid waste management plan and assurances that adequate solid waste landfill capacity exists prior to approval of individual development projects. Overall, no impacts to provision of public services not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. 14. Recreation Environmental Setting The Project Area is currently vacant and contains no parks or other recreational amenities. Nearby community and regional parks include: Emerald Glen Park, a 50-acre City park being developed by the City of Dublin in Eastern Dublin and two community parks slated for development within the Dublin Ranch deveiopment one of which is in the Area B portion of the Amendment Area. The combined area of the two community parks is 126 acres. Each of these parks would allow for organized sports activities, individual sports as well as passive recreation. The East Bay Regional Parks District has developed a staging area on the west side of Tassajara Road as part of a regional recreational trail system. City of Dublin Page 49 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 The Eastern Dublin EIR identified the following impacts with regard to recreation facilities as applicable to this Project: · IM 3.4/K: Increased demand for park facilities, which would be a potentially significant impact. · IM 3.4/L: Park facilities fiscal impact, which would be a potentially significant impact. · IM 3.4/M: Impact on regional trail system, which would be a potentially significant impact. · IM 3 ~4/N: Impact on open space connectors, which would be a potentially significant impact. Mitigation measures contained in the Eastern Dublin EIR were adopted to reduce all of the above impacts to a less-than-significant level. The 1997 Negative Declaration for Planning Areas B-E and the 2000 MND prepared for Dublin Ranch PA F did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to recreational facilities. Project Impacts and Mitigation Measures a) WouM the project increase the use of existing neighborhood or regional parks? LS. The ~.. proposed development would cause an increase in demand for neighborhood, community ~i~' and regional park facilities due to an increase in the number of people within the Project Area. As part of the entire Dublin Ranch project, the developer has provided one 60-acre i~~ (net) community park facility, including active play fields as well as passive nature parks. ':~' Residents of the Project Area could be expected to use these community and regional facilities. For potential impacts to neighborhood parks, see the response to "b," below. b) Does the project include recreational facilities or require the construction of recreational facilities? LS. Based on an estimated total population of 2,725 for the Project Area (see Section 11, Population), and with a standard requirement of 5.0 acres of park land per 1,000 residents (1.5 acres for neighborhood parks and 3.5 acres for community parks), there would be a need for 4.1 acres of neighborhood parks and 9.5 acres of community parks within the Project Area. The proposed Specific Plan/General Plan Amendment makes provision for both a 5.6-acre neighborhood park and a 2.0-acre neighborhood square. Totaling 7.6 acres, construction of both the park and square would be consistent with the City neighborhood park requirement. A 60-acre (net) community park site is proposed within the Project Area, which would exceed the community park requirement. Overall, no impacts to provision of recreational facilities or services not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. City of Dublin Page 50 Initial Study/Dub in Ranch Areas B/F/E February 2004 PA 01-037 15. Transportation/Traffic (Refer to Letter regarding potential Project traffic and transportation impacts from TJKM Transportation Consultants in the Appendix.) ~xisting Transportation Network The project site is served by a number of regional freeways and sub-r~egional arterial and collector roadways, including: Interstate 580, an eight-lane east-west freeway that connects Dublin with local cities such as Livermore and Tracy to the east and Oakland, San Francisco and other cities to the west. In the vicinity of the project, Interstate 580 carries between 169,000 and 187,000 vehicles per day. Interchanges near the project site include Dougherty/Hopyard Road, Hacienda Drive, Tassajara Road/Santa Rita Road and Fallon Road/E1 Charro Road. Dougherty Road is a two-lane rural road with its northern section located in Contra Costa County. Dougherty Road has four lanes between the Alameda County/Contra Costa County border and Dublin Boulevard and six lanes between Dublin Boulevard and 1-580. South of 1-580, it continues with six lanes as Hopyard Road in Pleasanton. Average Daily Traffic is approximately 43,500 south of Dublin Boulevard. Dublin Boulevard is a major east-west arterial roadway in the City of Dublin. It contains four lanes largely fronted by retail and commercial uses west of Dougherty Road. Between Dougherty Road and Tassajara Road, Dublin Boulevard is a two-lane road with an exception between Hacienda Drive and Tassajara Creek, where it is a four-lane road. Average Daily Traffic varies from .approximately 29,300 vehicles east of San Ramon Road to 5,300 vehicles west of Tassajara Road. Hacienda Drive is an arterial designed to provide access to 1-580. It contains six lanes south of 1-580 and four lanes north of 1-580, extending as far north as Dublin Boulevard. As part of the Santa Rita Business Center, Hacienda Drive is currently being extended northward to Gleason Drive as a two-lane roadway. Between 1-580 and Dublin, the existing vehicle count is approximately 11,300. Arnold Road is a north-south two-lane road parallel to and west of Hacienda Drive. It currently connects Gleason Drive and existing Dublin Boulevard (future Central Parkway). This road is planned to be extended southward to Dublin Boulevard (ultimate alignment. The existing average daily traffic flow on Arnold Drive is approximately 3,500 vehicles per day. Gleason Drive is an east-west two-lane road parallel to and north of Dublin Boulevard. It serves the Santa Rita Rehabilitation Center, Federal Correctional Institute and existing developments along Gleason Drive. Gleason Drive connects Tassajara Road with Arnold Road and carries between 5,100 vehicles per day (west of Tassajara Road) to apProximately 1,000 vehicles per day (west of Hacienda Drive). Portions of Gleason Drive are being widened to four lanes2 Tassajara Road is a two-lane rural road connecting Santa Rita Road at 1-580 to the south and continues north to the Town of Danville. North of Contra Costa County line, it is named Cameo Tassajara and is used primarily for local traffic in the Tassajara Valley, City of Dublin Page 51 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 with some through traffic. The average daily traffic volume on Tassajara Road is F"' approximately 9,990 vehicles per day between Dublin Boulevard and Gleason Drive, and 7,500 vehicles per day north of Gleason Drive. Santa Rita Road is a six-lane divided urban arterial roadway from the 1-580 interchange south to Valley Boulevard. It serves the east side of Pleasanton, including the Hacienda Business Park and provides access to downtown Pleasanton. Fallon Road is a two-lane rural road that terminates approximately 1.1 mile north of 1- 580. Fallon Road provides access to several parcels in the East Dublin area. Traffic volumes on this road are relatively small. The Boulevard is a private driveway providing access into Hacienda Crossings, a major commercial development within Eastern Dublin. Existing Interxection Operations The traffic analysis prepared by TJKM found that existing intersections near the Project Area currently operate at acceptable levels of service, defined by the City of Dublin as Level of Service "D" or better. This analysis included counts of existing traffic at major intersections near the proposed project as well as intersections throughout the Eastern Dublin area. Future Baseline Conditions To implement the transportation and circulation aspects of the Eastern Dublin Specific Plan/General Plan, the City of Dublin has undertaken a comprehensive program of transportation improvements in the community. The purpose of this program ss to accommodate anticipated traffic from the Eastern Dublin area. Overall, the program includes upgrades to 1-580. freeway intersections, construction of new roads and improvements to existing roads. The program is primarily funded by fees levied on new development in eastern Dublin. A summary of major components of the Transportation Improvement Program [Mike, Jerry: I don't recall hearing about this specific program, is this the same as the TIF program?] adopted by the City is as follows. A full description of improvements is contained in the traffic analysis. · Hacienda Drive extension · Tassajara Road widening · Dublin Boulevard widening · Improvements to the following intersections, including adding additional travel lanes and/or modifying existing lane geometrics: :Tassajara Road/Dublin Boulevard, Tassajara Road/Central Parkway, Tassajara Road/Gleason Drive, Main Street/Central Parkway, Main Street/Gleason Drive. Fallon Road/Dublin Boulevard and Fallon Road/Gleason Drive. Future Baseline Intersection Operations The traffic impact analysis for this proposed project also analyzed the future baseline intersection' operations with existing traffic, traffic from approved but not yet built or occupied development and traffic from other pending developments in the area. The traffic analysis included various mitigation measures which would be the responsibility of these other developments and which would be consistent with the City's Traffic Improvement Program, described above. With this futUre development in the eastern Dublin area and appropriate traffic improvements, the traffic City of Dublin Page 52 Initial Study/Dublin Flanch Areas B/F/E February 2004 PA 01-037 analysis found that the operation of all study intersections could be maintained at LOS "D" or better. Previous environmental documents The Eastern Dublin EIR identified 16 potentially significant and potentially cumulative significant impacts related to the development of the EDSP. These include impacts to nearby freeways, local streets, transit service and similar transportation facilities. Although many of these impacts could be reduced to level of less-than-significance, a Statement of Overriding Consideration was adopted for the following impacts: · IM 3.3/B: Impacts to mainline 1-580 and 1-680 freeways · IM 3.3/E; Cumulative Freeway impacts · IM 3.3/I: Santa Rita & 1-580 Eastbound freeway ramps · IM 3.3/M: Cumulative Impacts on Dublin Boulevard The 1997 Mitigated Negative Declaration for Planning Areas B-E did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to transportation. The 2000 MND prepared for Dublin Ranch PA F identified a number of new or supplemental impacts and mitigation measures from the Eastern Dublin EIR related to transportation. Supplemental Mitigation Measures 7 and 8 set forth in the MND would still apply to the proposed Project. Project Impacts and Mitigation Measures ~i~ a) Cause an increase in traffic which is substantial to existing traffic load and street capacity? LS. The traffic analyses for Planning Areas F, B and concluded that potentially significant impacts would be reduced to a less-than-significant level other than the four unavoidable impacts noted above. With the traffic improvements and mitigation measures associated with future approved and pending developments, all study intersections would operate at satisfactory LOS "D" or better conditions. However, with the additional trips generated by the development proposed in the Project Area, potentially significant impacts would occur at the following intersections: · Iron Horse Pkwy./Dublin Blvd.: LOS "E," PM peak; · Dougherty Rd./Dublin Blvd.: LOS "F," AM and PM peak; · Hacienda Dr./The Boulevard: LOS "F," PM peak; · Tassajara Rd/I-580 WB ramps: LOS "E," PM peak Adherence to Supplemental Mitigation Measure 7 and 8 contained in the Planning Area F Mitigated Negative Declaration will reduce this impact to a less-than-significant level. In addition, the project traffic impact analysis found that A new Statement of Overriding Consideration will be required if the proposed project is approved by the City of Dublin full development of the three Planning Areas (F-H) under the auspices of an approved General Plan Amendment/Specific Plan Amendment would potentially impact Tassajara ~ City of Dublin Page 53 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-O37 Road between 1-580 and Dublin Boulevard by exceeding the maximum capacity of this roadway segment. The maximum capacity of the roadway segment is estimated to be 50,000 vehicles per day. Future volumes along this roadway link could generate between 50,450 to 55,900 vehicles per day, depending on construction of other roadway 1.

These improvements will be confirmed at the time each individual development project is reviewed by the City. Individual project developers must also comply with Eastern Dublin EIR Mitigation Measure 3.3/16.1,.requiring pedestrian and bicycle paths cross arterial roadways at signalized intersections. With construction of pedestrian and bicycle improvements, impacts related to non-vehicular modes of transit would be reduced to a less-than- significant level. Overall, no impacts related to traffic and transportation not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration or PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. City of Dublin Page 55 Initial Study/Dublin Ranch Areas B/F/E ~ February 2004 PA 01 ~037 16. Utilities and Service Systems Environmental Setting The project site is served by the following service providers: · Sewage treatment and local water supply: Dublin San Ramon Services District and Alameda County Flood Control and Water Conservation District, Zone 7. · Water supply and distribution: Alameda County Flood Control and Water Conservation District, Zone 7 ° Storm drainage: city of Dublin/Alameda County Flood Control and Water Conservation District, Zone 7. The Eastern Dublin EIR contains 23 impacts related to provision of utilities to the Eastern Dublin area. All were considered potentially significant impacts and mitigation measures were included in the EIR to reduce these impacts to less-than-significant levels. .The 1997 Negative Declaration for Planning Areas B-E and the 2000 MND for Planning Area F did not identify new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to utilities. Environmental Impacts and Mitigation Measures a) Exceed wastewater treatment requirements of the RWQCB? LS. The regional wastewater treatment plant is currently operating in compliance with local, state and federal water quality standards. The addition of wastewater flows from the project would not cause the plant to exceed such standards, based on discussions with DSRSD staff. Mitigation measures 3.5/1.0 through 22.0 contained in the Eastern Dublin EIR deal with wastewater treatment collection, treatment and disposal. b) Require new water or wastewater treatment facilities or expansion of existing facilities? LS. Existing water and sewer lines would need to be extended into the Planning Area from the east. Such extensions have been planned as part of the East Dublin Specific Plan/General Plan and have been anatyzed in the Eastern Dublin EIR. c) Require new storm drainage facilities? LS. The project applicant has indicated that a new · drainage system would be constructed as part of the Project Area construction. Adopted mitigations will ensure that the proposed drainage system would accommodate Project storm water runoff. d) Are sufficient water supplies available? LS. Approval of the proposed project and implementation of new residences and other uses under the auspices of the Specific Plan/General Plan Amendment would result in an increased demand for water for domestic and irrigation purposes. This amount of increased water demand could be accommodated by DSRSD and Zone 7 facilities and long-term supplies. The project developer would be required to provide any local extensions and connections to nearby facilities. This Conclusion is based on information contained in the Eastern Dublin EIR. Consistent with Government Code section 65302.2, the DSRSD Eastern Dublin Facilities Master Plan has been considered in preparation of this Initial Study. City of Dublin Page 56 Initial Study/Dublin Ranch Areas B/F/E February 2004 PA 01-037 e) Adequate wastewater capacity to serve the proposed project? LS. Approval of the proposed Specific Plan/General Plan Amendment and construction of new residences and other land uses would increase the demand for wastewater treatment over present conditions. Presently, the Planning Area site is vacant and there is no demand for wastewater treatment service. Based on information contained in the Eastern Dublin EIR, DSRSD has indicated that the local wastewater treatment plant has adequate capacity to serve the proposed project. f) Solid waste disposal? LS. Construction of proposed land uses in the Project Area under the auspices of an approVed General Plan Amendment/Specific Plan Amendment would incrementally increase generation of solid waste. Over the long term, the amount of solid waste reaching landfill would decrease as statewide regulations mandating increased recycling take effect. Information contained in the Eastern Dublin EIR indicates that the solid waste hauler can accommodate this project. g) Comply with federal, state and local statutes and regulations related to solid waste? NI. The City of Dublin and the solid waste hauler would ensure that developers of individual projects constructed under the auspices of an amended Specific Plan and General Plan would adhere to federal, state and local solid waste regulations. Overall, no impacts related to utility provision not previously identified in the Eastern Dublin EIR, the 1997 Negative Declaration for PAs B-E, or the 2000 MND for PA F are expected to occur as a result of this Project. XV. 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 wiMlife species, cause a fish or wiMlife 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 recommended in the Initial Study. 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 and less-than-significant increases in certain areas can be expected as a result of constructing this project, including additional traffic, air emissions, noise, light and glare, the Project site lies within an area with an approved specific plan. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? No. No such impacts have been discovered in the course of preparing this Initial Study.

General. Pursuant to CEQA Guidelines section 15093, the City Council of the City of Dublin adopted a Statement of Overriding Considerations for those impacts identified in the Eastern Dublin EIR as significant and unavoidable. (Resolution 53-93, May 10, 1993.) The City Council carefully considered each impact in its decision to approve urbanization of Eastern Dublin through approval of the Eastern Dublin General Plan Amendment and Specific Plan project. The City Council later approved land use applications for Dublin Ranch, including Dublin Ranch Areas F, B and E. The City Council is cUrrently considering the Area F North project in Dublin Ranch. The project includes portions of Areas F, B, and E, and proposes residential, school, public/semi-public, and community park uses, generally consistent with prior approvals. The project area consists of approximately 285 acres, identified in the applications as the Amendment Area. The project proposes to reconfigure the uses in the Amendment Area, resulting in increased acreage for the Community Park, and reducing the overall number of residences. Approximately 88.5 acres of the Amendment Area is identified as the Development Area, for which permit level approvals are requested. Consistent with the prior approvals, the applicant obtained a Section 404 permit from the Corps of Engineers and has completed grading of the Development Area pursuant to the Corps permit. The City Council adopted a Statement of Overriding Considerations with the original land use approvals for urbanization of Eastern Dublin. Pursuant to a recent court decision, the City Council hereby adopts specific overriding considerations for the Area F North project. 1 The City Council believes that many of the unavoidable environmental effects identified in the Eastern Dublin EIR that are applicable to the Area F North site will be sUbstantially lessened by mitigation measures adopted with the original approval and by the environmental protection measures adopted through the Area F, B and E project approvals, and the related Conditions of Approval, to be implemented with the development of the project. Even with mitigation, the City Council recognizes that the implementation of the project carries with it unavoidable adverse environmental effects as identified in the Eastern Dublin EIR. The City Council specifically finds that to the extent that the identified adverse or potentially adverse impacts for the Area F North project have not been mitigated to acceptable levels, there are specific economic, social, environmental, land use, and other considerations that support approval of the project. 1 ,,...public officials must still go on the record and explain specifical'ly why they are approving the later project despite its significant unavoidable impacts." (emphasis original.) Communities for a Better Environment v. California Resources Agency 103 Cai.App. 4th 98, __ (2002). ATTACHMENT/ 2. Unavoidable Significant Adverse Impacts. The following unavoidable significant environmental impacts identified in the Eastern Dublin Eli=, for future development of Eastern Dublin apply to the Area F North project: Land Use Impact 3.1/F. Cumulative Loss of Agricultural and Open Space Lands; Visual Impacts 3.8/B; and, Alteration of Rural/Open Space Character. Although considerable development has occurred throughout Dublin Ranch, and a substantial amount of the project site will be maintained as a community park, much of the site is presently undeveloped land, and has some open space character. Future development of the Area F North site will contribute to the cumulative loss of open space land. Traffic and Circulation Impacts 3.3/B, 3.3/E. 1-580 Freeway, Cumulative Freeway Impacts: The Traffic Study prepared for the Area F North project and the Dublin Transit Center Eli=, update cumulative impacts to the 1-580 and 1-680 freeways from development in Eastern Dublin. While city street and interchange impacts can be mitigated through planned improvements, transportation demand management, the 1-580 Smart Corridor program, and the extension of Fallon Road to Tassajara Road and other similar measures, mainline freeway impacts continue to be identified as unavoidable, as anticipated in the Eastern Dublin Eli=,. Future development on the Area F North site will incrementally contribute to the unavoidable freeway impacts. Traffic and Circulation Impacts 3.3/I, 3.3/M. Santa Rita Road/I-580 Ramps, Cumulative Dublin Boulevard Impacts: The Area F North project will be required to implement all applicable adopted traffic mitigation measures, including contributions to the City's TIF program; however even with mitigation these impacts continue to be identified as unavoidable, as anticipated in the Eastern Dublin Ell=,. Community Services and Facilities Impact 3.4/S. Consumption of Non- Renewable Natural Resources and Sewer, Water; and Storm Drainage Impact 3.5/F, H, U. Increases in Energy Usage Through Increased Water Treatment, Disposal and Operation of Water Distribution System: Future development of the Area F North project will contribute to increased energy consumption. Soils, Geology, and Seismicity Impact 3.6/B. Earthquake Ground Shaking, Primary Effects: Even with seismic design, future development of the Area F North project could be subject to damage from large earthquakes, much like the rest of the Eastern Dublin planning area. Air Quality Impacts 3.11/A, B, C, and E: Future development of the Area F North project will contribute to cumulative dust deposition, construction equipment emissions, mobile and stationary source emissions. 3. Overriding Considerations. The City Council previously balanced the benefits of the Eastern Dublin project approvals against the significant and 682986-1 2 potentially significant adverse impacts identified in the Eastern Dublin EIR. The City Council now balances those unavoidable impacts that apply to future development on the Area F North site against its benefits, and hereby determines that such unavoidable impacts are outweighed by the benefits of the Area F North project as further set forth below. The project will further the urbanization of Eastern Dublin as planned through the comprehensive framework established in the original Eastern Dublin approvals. Future development would provide planned housing as well as a 65 acre Community Park and land for Public/Semi Public uses. The project provides the potential for approximately 1,290 dwelling units at Iow and medium densities, as well as construction jobs, in an area convenient to major transit facilities, schools, and proposed parks. Area F North is also convenient to existing and future housing in Dublin, will provide affordable housing through the Fairway Ranch project, and could substantially increase property tax revenues.
