The proposed project involves the approval of the Dublin Transit Center by the City of Dublin as well as related amendments to the Eastern Dublin Specific Plan and General Plan, a Stage 1 PD (Planned Development) rezoning, a Tentative Parcel Map and Development Agreement. A full description of the proposed project is contained in the DEIR document. Under the California Environmental Quality Act (CEQA) and implementing CEQA Guidelines, after completion of the Draft EIR, lead agencies are required to consult with and obtain comments from public agencies and organizations having jurisdiction by law over elements of the project and to provide the general public with an opportunity to comment on the Draft EIR. Lead agencies are also required to respond to substantive comments on environmental issues raised during the EIR review period, As the lead agency for this project, the City of Dublin held a 45-day public review period between July 6 and August 21, 2001. Based on information uncovered in the response to comments, a new significant and unavoidable traffic impact was discovered and the City re-circulated this new impact pursuant to CEQA Guidelines Section 15088.5 for a second 45-day period between July 16 and August 30, 2002. The re-circulated document is included as Appendix A. This document contains all public comments received during the 45-day public review process regarding the DEIR and responses to those comments. Included within the document is an 'annotated copy of the comment letter, identifying specific comments, followed by a response to that comment. Comments and responses related to the re-circulated impact are also included. The FEIR also contains clarifications and minor corrections to information presented in the DEIR as well as revisions to the proposed project. Clarifications and Modifications to the DEIR The following substitute Mitigation Measures for those contained in the Draft EIR are hereby made by reference. Responses to the Department of Fish and Game comments contain further discussion of these modifications. Transit Center PA 00-013 Page 2 City of Dublin September 2002 1) Mitigation Measure 4.3-1 (Congdon's tarplant, also known as spikeweed) is changed to read as follows: The size of the area occupied by the tarpIant should be determined from the field survey and notes on past on-site distribution, measuring the entire area from which the plant has been observed. If on-site avoidance is not possible, one of the following options must be taken to ensure replacement on a 1:1 acreage ratio: a. Permanently preserve, through use of a conservation easement or other similar method, equal amount of off-site acreage that contains the plant; or b. Harvest seeds from on-site plants to be lost or from another source within the Livermore-Amador Valley, and seed an equal amount of off-site area suitable for supporting the plant which shall be preserved and protected in perpetuity. Prior to submittal of a tentative map and/or a Site Development Review (SDR) application, the project developer shall submit a Mitigation and Monitoring plan to the City for its review and approval, demonstrating how the developer will comply with this mitigation measure, including the steps they will take to ensure that reseeding will be successful. If Option" b" is selected and is not successful, Option "a' shall be implemented. 2) Mitigation Measure 4.3-3 (a) and (b) (Burrowing Owl) is hereby changed to read as follows: · Pre-construction surveys by a qualified biologist shall be conducted on the entire Project area and within 150 meters (500 feet) of the Project area within 30 days prior to any ground disturbance. If ground disturbance is delayed or suspended for more than 30 days after the pre-construction survey, the site shall be resurveyed. · If over-wintering birds are present (September I to January 31) no disturbance should occur within 160 feet of occupied burrows unless the Department of Fish and Game provides a letter giving consent to relocate wintering birds. If owls must be moved away from the disturbance area, passive relocation techniques, following CDFG 1995 guidelines, should be used rather than trapping. If no over- wintering birds are observed, burrows may be removed prior to the nesting season to reduce impacts from noise, dust, and human disturbance to mated pairs. · ' If removal of unoccupied potential nesting burrows prior to the nesting season is infeasible and construction must occur within the Transit Center PA 00-013 Page 3 City of Dublin September 2002 breeding season, maintain a minimum buffer (at least 250 feet) around active burrowing owl nesting sites identified by pre- construction surveys during the breeding season to avoid direct loss of individuals (February I - September 1). Ail active burrows shall be identified. If construction is scheduled during summer, when young are not yet fledged, a 250-foot exclusion zone around the nest shall be established or construction shall be delayed Until after the young have fIedged, typically by August 31. · When removal of occupied burrows is unavoidable, existing unsuitable burrows should be enhanced (enlarged or cleared of debris) or new burrows created (by installing artificial burrows) at a 2:1 ratio on protected lands, as provided for below. · A minimum of 6.5 acres of foraging habitat per pair or unpaired resident bird, shall be acquired and permanently protected. The protected lands shall be adjacent to occupied burrowing owl habitat and at a location acceptable to CDFG. · The project proponent shall prepare a management plan and provide funding for long-term management and monitoring of the protected lands. The monitoring plan should include success criteria, remedial measures, and an annual report to CDFG. 3) The location of the 24-inch Santa Rita-Dougherty pipeline is hereby corrected by reference On Exhibits 11 and 19 to be located along the former Southern Pacific Railroad right-of-way. 4) The following Zone 7 water supply numbers are hereby updated as requested by Zone 7 staff. On page 173 of the DEIR, Zone 7's sustainable water supply from the State Water Project is 84,100 acre-feet per year. On page 174, Lake Del Valle has a sustainable average yield of 9,300 acre-feet per year. 5) The subsection entitled Alameda County Congestion Management Agency on page 145 of the DEIR is hereby changed to read as follows: "Freeway impacts are significant if the amount of traffic is increased substantially so as to exceed Alameda County Congestion Management Agency (ACCMA) standards for the LOS Monitoring Program. ACCMA has established LOS standard of E for the Congestion Management Program (CMP) roadway network, except where F was the level of service originally measured, in which case the standard shall be F. Although the LOS E standard was established for the purpose of monitoring existing level of service conditions for the Alameda County CMP Designated Roadway System, this standard provides a standard of significance for determining potential project Transit Center PA 00-013 Page 4 City of Dublin September 2002 environmental impacts on adjacent freeway systems within Alameda · County, In the project study area, ACCMA has also identified 1-580, 1-680, Dublin Boulevard, Dougherty Road/Hopyard Road, Tassajara Road/Santa Rita Road, and San Ramon Road/Foothill Road as the Metropolitan Transportation System (MTS) routes that are subject to the CMP Land Use Analysis Program requirements. Since the City's standard is LOS D for Dublin BoUlevard, Dougherty Road, Tassajara Road and San Ramon Road, the LOS E standard (except where F is the level of service without Project traffic, in which case the standard is F) is applicable only to freeways. ACCMA Land Use Analysis Program guidelines also specify that any proposed project generating 100 PM peak hour trips over existing conditions must conduct a traffic analysis of the project using the Countywide Transportation Model for the base years 2005 and 2020. However, the guidelines also allow for other transportation models/projections to be used and Year 2025 must be compared to the Countywide Transportation Model to ensure that the more conservative of the two traffic projections are used for CMP purposes. Discussions with ACCMA staff in November 2000 indicate that Year 2025 analysis using the Tri-Valley Transportation Model would be appropriate to use for the Proposed Dublin Transit Center project. Compared to the Countywide Transportation Model, the Tri-Valley Transportation Model represents a more specific and focused travel demand-forecasting tool for the Tri-Valley area of Alameda County and is generally the more conservative of the two models." Revised Project Description Based on discussions with City of Dublin staff, minor changes have been made to the underlying project description since completion of the DEIR and recirculation of one of the traffic impacts. Specifically, previously planned Campus Office uses on Site F are proposed to be replaced with a 8.73-acre (net) neighborhood park. Campus Office uses previously shown on Site F have been redistributed onto adjacent sites within the project area. Revised Table 2 shows the location and extent of development currently being proposed in the Transit Center. Based on CEQA Guidelines Section 15088.5,the revised project description has been reviewed by the City of Dublin and it has been determined that the proposed change would not result in any new, significant impact that has not already been disclosed in the Draft Environmental Impact Report or the Re-circulated Impact. Anticipated traffic impacts of proposed park construction have been deemed less~ than-significant by the City of Dublin Traffic Engineer (found in Appendix C) due to Transit Center PA 00-013 Page 5 City of Dublin September 2002 the large residential component within the Transit Center that would result in non- automotive access to the proposed park (walking and bicycling). Anticipated increases in water uses for irrigation of turf and plants would be somewhat greater than included in the original DELR, but would still be less-than-significant, since recycled water from Dublin San Ramon Services District would be used for this purpose rather than fresh water.

This project has the potential to have a negative impact on Parks RFTA. The mitigation measure listed for helicopter noise from Parks P,_FTA states that residents will be given advanced notification of helicopter overflights. The DE[R does not state who will make these notifications or how they will be made. A general disclosure statement is enclosed to assist the City of Dublin with this notification process. If you have any questions, please contact Mr. Marshall Marik at (925) 803-5638. Sincerely, ee Lieutenant Colonel, U.S. Army' Commanding Officer A statement similar to the one below should be included in general disclosures .for developments adjacent to the property. If you have any questions, please contact Mr. Marshall Marik, DTC, Environmental Manager, at (925) 803-5638. General Disclosure Statement Significant Property Uses in the Vicinity of (name of the development). Parks Reserve Forces Training Area (Parks RFTA). Parks RFTA (a.k.a. Camp Parks) is an U.S. Army Reserve installation located approximately (distance...~. from (name of the developmenO. Parks RFTA has approximately 700 acres of administrative facilities and over 2,000 acres of open grassland for year-round weapons and field training. Activities with the potential to generate significant noise levels Outside of Parks RFTA include: weapons firing; artillery simulator activation, tactical vehicle operation; field power generator operation; and low level helicopter operations. Helicopters enter and exit from the northern and eastern boundaries of Parks RFTA. The noise from these helicopters directly overhead at an altitude of 500 feet will approach 90 A-weighted decibels (dBA). Historically, 35% of populations exposed to 90 dBA are expected to be highly annoyed. Parks RFTA periodically conducts controlled burning activities, which generate large amounts of smoke but provide a measure of protection from catastrophic fire events. BUyers of homes adjacent to Parks RFTA should carefully consider the impact of ~:.,~:.:.." .nuisances including, but not limited.to, noise; smoke, and dust.

How do the 1-580 intersection improvements mentioned on Page 167 fit in with the 2.1.3 mitigation measures that Cisco Systems needs to address? 4. Mitigation measures at Dougherty Road/I-580 and hacienda Drive/1-580 interchanges (Page 2 .'] .4 167) involving on-ramps need to include the ramp metering system and the HOV bypass lane. 5. Year 2025 forecast for 1-580 mainline (Table 25, Page 166) shows minimal project traffic for 2.1.5 the peak commute directions (westbound AM and eastbound PM). We recommend closer study of this situation. 6. The site for the Dublin Transit Center is less than one mile from the 1-580/1-680 interchange. 9. ~ .6 Please discuss the impacts to 1-680. In conclusion, we emphasize that the Dublin Transit Center DEIR shoUld not ignore the 2. 'l .7 significant impacts that will occur with project implementation, including those impacts that occur outside of its area of jurisdiction. These would include the significant traffic impacts to the 1-580 mainline. The California Environmental Quality Act mandates that public agencies avoid or minimize the significant effects that the' project would have on the environment, whenever possible. We believe that there are feasible mitigation meaSures that will lessen the 2. ~. 8 impact the project will have on State transportation facilities. The City of Dublin, as lead agency, needs to quantify the traffic impacts identified in the DEIR, develop measures to mitigate those impacts, and incorporate those measures into the final EIR.

We have ex~ · e Dr~ Environmental ~pact ~e~ and ha~e ~e following come, ts to offer: i. We are very concerned about thc additional traffic volume that this project Will add to 2.1.1 Interstate 5g0 (l-5g0). The Dublin Transit Center will add about 10% to the 1-580 peak hour traffic volume for eastbound in the morning and westbound in the evening. The Draft EIR (page 166), states that the Dublin Transit Center traffic would worsen the mainline freeway condition and have "significant and unavoidable impact." We concur that the additional traffic is certainly significant. We disagree, however with the continued discussion of Impact 4-11-7, which cites that "mitigation is not feasible since freeway improvement is not under the jurisdiction of the City of Dublin." This statement is shortsighted. Regardless of who has jurisdiction, these significant traffic impacts need to be mitigated. The Department urges the City of Dublin to participate in the development and funding of mitigation measures. 2. Regarding mitigation of the additional traffic to 1-580, we recommend the following 2.1.2 mitigation measures to control, monitor, and improve the freeway traffic conditions: · Providing adequate storage for ramp metering queues at the on-ramps and adjacent medal streets at all the impacted on-ramps and interchanges for a more effective ramp metering operation. · Providing High Occupancy Vehicle (HOV) bypass lanes at the metered on-ramps and impacted interchanges. · Installing Closed Circuit Television (CCTV), Changeable Message Signs (CMS), Traffic Monitoring Stations, and other Traffic Operation Systems elements.

Unavoidable impacts may be mitigated through a Mitigation Agreement acceptable to the Department to compensate for the loss of CTS habitat. Pre-construction surveys are proposed to be conducted to 2.3.3 mitigate for impacts to burrowing owl (Athene cunicularia) . The Department considers this proposed mitigation to be inadequate~ Surveys according to established Department protocol should be conducted on the entire project site and within a 500-foot zone around the project site during the nesting and non-nesting seasons. Buffers should be established around occupied burrows at all times of the year, not only during the breeding season. Disturbance of burrows used by owl pairs or single birds during the nesting or non-nesting season should be mitigated by the completion of a Mitigation Agreement with the Department and the acquisition and conservation of 6.5 acres of suitable owl habitat per owl pair or single bird in a location acceptable to the Department. San Joaquin kit fox (Vu!pes macrotis mutica) is presumed 2.3.4 absent from the site. The Department does not concur with these findings. The area is in' the western range of the kit fox and suitable foraging habitat exists on the project site. In this area, because kit foxes occur in iow numbers and the detection rate is iow even in areas where they are known to be denning, negative findings based on the survey methods employed are not acceptable. Close consultation with the Department and the U. S. Fish and Wildlife Service (USFWS) will be needed to assure compliance with the State and Federal Endangered Species acts. Loss of habitat is considered a taking under these acts and will require permits from both agencies. Currently, mitigation standards for permanent loss of habitat require compensatory preservation of habitat. Information on what lands are propose~ be acquired or otherwise preserved as mitigation should be disclosed. Congdon's tarplant (Hemizonia parryi ssp. congdonii) was 2.3.5 observed on the site. A thorough field survey, conducted according to the Department's Rare Plant Survey Guidelines by a qualified botanist during the appropriate months, is needed to determine the extent of these species on the project site. The California Environmental Quality Act (CEQA) Guidelines Section 15380(d) states that these species be addressed as other threatened and endangered species and adequate mitigation be ~r. Eddie Peabod~ August 21, 2001 Page 3 provided for any impacts. The Department recommends that impacts be avoided in areas where these species occur on the project site. Conservation areas should also include an appropriate buffer. The Department does not approve of trans!ocation as an acceptable mitigation measure. There is no evidence to support that translocation is a successful technique to perpetuate populations of these plant species and, therefore, the proposed mitigation is viewed as experimental, and does not meet the mitigation standards of CEQA. if avoidance of impacts to this species is not possible, a Mitigation and Monitoring Plan should be developed that will provide for off-site conservation of populations cf these species. The plan should be reviewed and approved by the Department. Surveys to be conducted at a later time, or mitigation measures to be identified at some future time, are not acceptable. It has been determined by court ruling that such studies and mitigation measures would be improperly exempted from the process of public and governmental review which is required under CEQA. The document requests future studies and future identification of mitigation and, therefore, is considered inadequate. It is the Department's opinion that mitigation measures proposed for this project will not reduce the effects or mitigate the effects to a point where clearly no significant effect on the environment would occur. Based on new information and cumulative impacts, the Department does not believe that the DEIR for the Dublin Transit Center establishes appropriate mitigation for special status species. It is the policy of the Department that a project should 2.3.6 cause no net loss of either wetland acreage or wetland habitat value. In 1995, Bay Area Rapid Transit filled 2.88 acres of wetlands on the site. Wetlands were created on Camp Parks as compensation. These wetlands have never functioned properly. Acceptable mitigation for all wetlands areas affected by the project should be proposed. A Streambed Alteration Agreement must be obtained from the 2.3.7 Department prior to any work in a lake or stream corridor. Since [ the issuance of such an Agreement is subject to CEQA review, disclosure and incorporation of mitigation measures requested by the Department is needed to meet the requirements of CEQA.

The DEIR states that BART assumes a ridership load 3.2.4 capacity of 1.35 per train during peak commute periods, which would effectively allow for additional capacity on each BART car. According to the CMP, this load factor is only applied to the average peak hour, peak direction transbay load factor for all four BART routes. A load factor of 1.15 is used for all other directions and times of day. The assumed load factor and the ability of BART to accommodate the additional passengers generated by the Transit Village project should be verified with BART staff. )~ Page 157: For CMP purposes, the roadway network used to analyze project 3.2.5 impacts on the MTS must be consistent with the 2005 C1V[P Capital Improvement Program and 2025 CWTP Investment Program: Also, all improvements assumed in the base networks must have full funding identified. Please verify how the projects listed on page 157 are fully funded.

Our agency has identified no impacts or necessary mitigations beyond those identified in the Draft EIR. Our comments on the specific areas of our service to the community in the area of the TranskCenter are detailed below. Potable V~ater Supply and Service' As you point out in the draft EIR, this project will create demand for an additional 447,000 3.3.1 gallons per day of potable water. Because of the planning already done by DSRSD in cooperation with the City of Dubtin'a demand of 185,000 gallons per day for the Transit Center is already incorporated into DSRSD's Urban Water Management Plan. The impact of the full development of the Transit Center will be an additional demand of 262,000 gallons per day. As you point out in your report, the facilities currently planned by DSRSD for this area will be of sufficient capacity to meet the increased demand at full build out of this project; and this demand will be mitigated somewhat by the extension of recycled water pipelines through the project area and adherence to Dublin's standard water conservation measures. The supply of the 447,000 gallons of potable water for this project is provided for in the long- term contracts between the Zone 7 Water Agency and DSRSD. No additional mitigation is necessary is necessary for obtaining additional water supply for this project. Recycled Water Supply and Service 3.3.2 As you note in the Draft EIR, DSRSD Ordinance No. 280 requires recycled water use for all new land uses that are commercial, multi-family residential and institutional irrigation within the DSRSD potable water service area. The development of the Dublin Transit Center falls into these categories. In your report you show an expected demand for recycled water of 27,500 gallons per day for irrigation and an additional 2,200 gallons per day for cooling at the electrical generation facility. The sum of these two demands equals 29,700 gallons per day, or 33.3 acre-feet per year. Currently, DSRSD's Recycled Water Plan has 10 acre-feet per year of reclaimed water reserved for the Dublin Transit Center project. The anticipated shortfall of 23.3 acr~feet per year is G:kENGDEPTxDept Items~AsstE~gl~Ltr8 - Draft EIl~helil~l&~ ~i's~Banler~l~ Distr~ct is a ~blic Entity Mr. Eddie Peabody ' City of Dublin August 16, 2001 Page 2 of 2 expected to be mitigated in the long term by upgrades now planned for DSRSD's Recycled Water Reclamation Plant. In the short term, sufficient potable water supplies are available to supplement the Recycled Water Supply as necessary. Wastewater Services and Wastewater Effluent Disposal The Draft EIR notes that the Transit Center Project will generate 447,000 gallons per day of 3.3 · 3 wastewater flows at full build out. Also noted is the inclusion of this wastewater demand in the planned capacity expansions of DSRSD's Wastewater Treatment Plant and LAVWMA's wastewater effluent disposal facilities. No further mitigation appears to be necessary. As noted above, our agency does not deem ~.y mitigation beyond those specified in the Draft 3.3.4 EIR for the areas of our Potable Water, Recycled Water or Wastewater Collection and Disposal services to the community. We feel that the joint planning effort done between the City of Dublin and DSRSD has successfully identified those areas of concern and planned reasonable solutions to those areas.

Bev=.rly Lane Ward 6 RE: Comments on PA 00-013 Dublin Transit Center Draft Environmental caro~ Sevorin Impact Report-Iron Horse Regional Trail Ward 3 Jean Sir~ Ward 1 Dear Mr. Porto: Pat O'Brien East Bay Regional Park District (the "DistriCt"), has received the Draft Environmental Genere} Manager Impact Report (DEIR) for the PA 00-013 Dublin Transit Center and would like to make the following comments regarding the Iron Horse Regional Trail, circulation, and impacts on recreation. The Iron Horse Trail, managed by the District, is both the main recreational feature in 3.4.1 the Diablo and San Ramon Valleys (and Tri-Valley in the future) as well as an important component of the non-motorized transportation system in Alameda and Contra Costa Counties. The multi-use, paved trail (10-foot paved asphalt with 2-foot gravel shoulders on either side) currently extends more than 23 miles between Concord and Dougherty Road in Dublin, with the extension to the Dublin/Pleasanton BART Station to be constructed in the westerly end of the proposed Transit Center Area (scheduled for 2002). Beyond the BART Station, furore Iron Horse Trail is being planned to continue south to Shadow Cliffs Regional Recreation Area in Pleasanton and eastward through Livermore to the San Joaquin County line connecting to major job centers in Pleasanton such as Hacienda Business Park. Connections of the Iron Horse Trail to multi-modal transportation facilities such as BART Stations are a goal of the District, Alameda County, and BART, as are connections to employment destinations, schools, commercial areas, and residential areas. Currently, the trail connects directly to the Pleasant Hill BART Station and is located less than a mile away frOm the Walnut Creek BART Station. The agencies have collaborated on providing maps of regional trail and park facilities in all the BART Stations as well as on BART'S "Pathfinder" program to develop directional signage and information to BART riders who may walk or ride the trail to their ultimate destinations. The Iron Horse Trail also functions as the major spine trail in the two counties cormecting seven Cities and other local and regional trails. For example, commuters and recreational users will be able to access the trail along Dublin Blvd which will connect to the Tassajara Creek Regional Trail and provide'non-motorized connections to the Transit Center for the thousands of new ~ RECEIVED ~ AUG g I ZOO! ~ DUBLIN PLANNING ~  2950 Peralta Oaks Court P.O.

A similar urban development project which incorporated concepts of'?qew Urbanism" and pedestrian friendly design and mixed uses was recently completed for the Pleasant Hill BART Station area under the direction of the Contra Costa County Redevelopment Agency. The Iron Horse Trail was consistently brought out as the major regional facility which provides non-motorized transportation oppommities for commuters, school-aged children, and residents who will be able to access the trail to travel to shopping areas, other residential areas, and other multi-modal transportation facilities thereby reducing vehicle emissions and creating an enhanced "livable community". Environmental Impacts Impact 4.1-2. The DEIR states that the proposed project would reduce existing views of 3.4.2 Mt. Diablo and the surrounding ridgelines from some public viewpoints, including the I Iron Horse Trail, creating a significant impact. The Iron Horse Trail provides a greenway as well as a functional trail connection, therefore, preserving views of surrounding open space is important. The corridor should not be blocked offby buildings or walls, nor resemble a roadway between two soundwalls. Impact 4.13-1. The DEIR states that the proposed project would be considered a 3.4.3 si~cificant impact if there is a demonstrable increase in the use of a local, community, or Regional Park, playground, or recreational facility. And, that implementation of the proposed project would increase the demand for such facilities. The DIER states that this impact is deemed less-than significant due to the type of proposed residential facilities that would not be primarily occupied by families with small children due to space constraints. Under Impact 4.13-2, the DEIR states that use of regional facilities, particularly the Iron Horse Trail, will also increase with approval and implementation of the Transit Center. The proposed project will result in an addition of 1500 residential units and an estimated population of 3000 new residents. Even if the majority of new residents are adults, there will be an increase in demand of regional facilities, such as the Iron Horse Trail. The District has surveyed Iron Horse Trail users (EBRPD 1997) and found that the trail serves each age group in accordance with its proportion of the community, with the highest proportion being adults and teenagers. Planning for these increases by providing adequate bicycle and pedestrian facilities and infrastructure will be very important to ensure smooth circulation amongst future users of the Transit Center. The DEIR states that the project will be subject to impact fees to pay for community park facilities on a City-wide basis and that the Tri-Valley Transportation Development Fee 2 (another City-wide impact fee) funds regional traffic improvements. Financing bike and pedestrian friendly facilities at the Center, on arterials and connectors in the project area, and links to the proposed Village Green should be considered an appropriate use of these funds. Staging/Parking for trail users should also be identified which could include dedicated 3.4.4 parking in the vicinity of the Iron Horse Trail and regulating parking to allowed shared parking for trail users,' including weekends. The Transit Center itself will attract trail users who will want to access the Iron Horse Trail and also shop or dine at the Center. Recommended bicycle design practices, guidelines for bicycle parking, signal 3.4.5 standards, facilities such as short term, long term, and stationed bicycle lockers and storage options, bicycle maintenance stations, etc. are outlined in the recently completed Alameda Countywide Bicycle Plan, sponsored by the Alameda County's Congestion Management Agency (CMA). This document was developed by a Bicycle Task Force with representation of the City of Dublin, all cities in Alameda County and other bicycle organizations and regional agencies, including East Bay Regional Park District, in order to provide consistent guidelines for bicycle planning countywide and provide information facilities which can be incorporated into Transit Center design to encourage bicycle and pedestrian travel as an alternative to vehicle travel.

A 15% reduction was given to Office generation and a 25% reduction to Residential development. Total peak hour trips were calculated to be some 4,155 AM and 3,970 PM. Trips generation calculations were based on some 2 million Sq. Ft. of Office and 1500 Multi Family residential units along with BART ridership and 70,000 Sq. Ft of Retail. All rates used are substantially less than those used in Pleasanton as shown below. Land use Pleasanton Transit Center Office AM 1.33 1.25 PM 1.33 1.18 Multi Family AM 0.56 0.38 PM 0.70 0.47 Retail Promotional Center AM 1.42 2.59 PM 3.36 2.59 In as much as BART is only oriented to trips to the WEST and the TOTAL percent of workers from the west is only about 25%, a I5% reduction is generous and may understate the traffic impacts of high rise office. In a like vein, the residential trips oriented to jobs in the west are also about 25%. And while as many as 25-35% of the trips may work locally the reductions for residential axe also less than conservative in terms of traffic impact. The Retail, in the critical PM peak period, also seems to be overly conservative. It is indicated on Page 147 that there is no additional BART traffic as, "The proposed BART parking 3.5.3 structure would not add any additional parking spaces to the existing East Dublin Bart Station." It would appear that the proposed development might preclude the any future increase in number of BART spaces. In that the surface area devoted to BART is significantly decreased, if there is clearly a loss of future BART parking capability this should be stated. Traffic analysis was done for "Future Base Traffic Conditions" (year 2005), which include "Existing" 3.5.4 traffic plus "Approved" traffic but not Project Traffic. Such traffic projections showed that there were problems at Dougherty and Dublin Boulevard with projected LOS "E" AM and "F" PM. These problems would influence the traffic operations at Dougherty and WB 1-580 and Hopyard and EB 1-580. Such should be noted in the report. It is our understanding that the improvements needed to mitigate the impacts shown on Pg. 141 are currently not funded in the short term CIP Program. Mr. Michael Porto Project Planner Dublin Community Duvelopmcnt Dopartment August 21,2001 Page 3 The "Cumulative year 2025 with Project LOS Projections" indicates several problem areas. The most 3.5.5' significant is at the Dublin Dougherty intersection. Average daily traffic volumes on the section of Dougherty from 1-580 to Dublin Boulevard are projected to double from the current 40,000 trips to day to some 80,000. Dougherty Road and Dublin Boulevard Intersection The proposed widening creates an 8-lane northbound section; 3 left, 3 thru and 2 right, with a 4 lane 3.5,6 southbound. The southbound approach is proposed to be widened to 6 lanes 2 left, 3 thru, and 1 right. WB would be 6 lanes, 3 left 2 thru and 1 thru & right. Eastbound would be 6 lanes 1 left 3 thru and 2 right. With this configuration the LOS would still be 0.97 "E" AM, and 1.06, "F" in the PM. There seems to be some confusion on mitigations and levels of service of the Dougherty/Dublin intersection. In the summary pages 1-32 impact 4.11-1 b) intersection widenings are cited with resultant 'LOS."D" In PM of 0.86 On page 1-37 impact 4.11-5 We show additional lane widening with a projected PM LOS of "F" 1.06. Table 23 pg 160 and text on pg. 161 shows the intersection at 0.97 AM and 1.06'PM. Table 7 of the appended Omni Means report Seems to confnm the LOS "F" conditions. Staff believes that in order to accommodate these levels of traffic volumes that restriping of the Hopyard overpass will be required to create additional lanes. This should be so indicated, A 3.5.7 queuing analysis is needed to determine the actual levels Of congestion along HopyardfDougherty from Owens Drive north of Dublin Blvd. ~through ScarieR. The dose proximity of the intersections will have a significant impact on operations and actual delay and levels of service. Dublin Boulevard should also be studied due to the close proximity of Scarlett Drive to the intersection and the obvious need to run long traffic signal cycles. Hacienda Interchange The current interchange desigu studies indicated that the EB off ramp required widening. In 3.5.8 order to accommodate the transit village, it was determined that the WB intersection needed. NB 3 thru lanes and a right turn lane. This is different than the proposed WB offof3 left and 2 right lanes. In conclusion while the report does a good job in identifying the problem areas it is lacking in 3.5.9 de£ming the actual impacts. While the use of intersection V/C LOS figures are informative, the actual street system designed for Dublin has placed many intersections of major proportion quite close together. In order to better determine the traffic impacts of these significant traffic volumes and significant increases in traffic it is requested that Dublin pursue the development of traffic simulation models to better determine the interaction between Dublin, Caltrans and Pleasanton intersections. The traffic volumes projected as arriving from the freeway and departing to the freeway are well above capacity. Given this the actual traffic volumes at our intersections will be Mr. Michael Porto Project Plarme~ Dublin Community Development Department August 21,2001 Page 4 . less than projected and the demand will exceed capacity at the ramp terminals; A more defmitive analysis is needed of these ramp queues and how they may be accommodated; Possible mitigating measures should include continued Cooperation of the 1-580 Smart Corridor project and future projects and a commitment to improved TSM programs with the new Office tenants in terms of what they will do to help achieve the reduced trip generation numbers. What will the 3.5.10 requirements be to improve their employees access to ACE, WHEELS and BART?

DUBLIN PLANNING ~: 373-5230 · F~: 37~-5295 Mr. Michael Porto, Project Planner August 21,2001 Page Two · Regional traffic congestion · Adequate water supply · Regional jobs/housing ratios · Housing affordability Our comments on these regionally important issues are more fully described below. Regional Traffic congestion 3.6.1 As noted on page 165 of the Draft EIR, congestion on 1-580 is projected to operate at unacceptably poor, LOS F conditions during peak commute periods by year 2025, even without the proposed project. The Draft EIR recognizes that the addition of project-related trips to this 1-580 congestion would be a significant and unavoidable imPact. In fact, according to information presented in Table 25 of the Draft EIR, the project's contribution of traffic on 1-580 during the peak hours is estimated to be approximately 4 percent to 5 percent of the total cumulative traffic on this roadway. However, the Draft'EIR identifies only one partial mitigation measure for this imPact, that being payment of regional traffic impact fees. As evidenced in the TVTC's own studies, the regional traffic fee has been demonstrated to be inadequate in meeting the pro-rata share of needed regional transportation improvement funding, and additional funding sources are needed. The DEIR suggests that no other mitigation is feasible since freeway improvements are not under the jurisdiction of the City of Dublin. However, there are feasible mitigation measures that can be applied to this 3.6 project, as well as all other cumulative development within the City of Dublin that can address this regionally significant impact. Such measures include: · Increased financial contributions toward the construction of high occupancy vehicle (HOV) lanes on 1-580. · "Fair-share" contributions toward completion of North Canyons Parkway/Dublin Boulevard extension as a six-lane roadway. · Providing increased funding for improved transit opportunities. Mr.' Michael Porto, Project Planner August 21,2001 Page Three The EIR should analyze the appropriate level of contribution by the project for the implementation of these measures. The need for mitigation of increased regional traffic congestion on a project-by-project basis is evidenced by the list of cumulative development already approved in the City of Dublin, shown on page 140 of the Draft EIR. According to this list, the City of Dublin has already approved more than 4 million square feet of additional commercial/office space and 4,800 new residences. This amount of cumulative development will have substantial adverse effects on traffic congestion levels on 1-580. Passing the responsibility for transportation improvements needed to accommodate this cumulative development onto Caltrans, or other regional agencies, does not address the responsibility that this cumulative development has toward assisting in regionally-based solutions. The City of Livermore has recently adopted a regional component to our local 3.6.3 traffic impact fee program. The purpose of this regional component is to provide additional sources of funding that can be used to assist in financing 1 regional transportation and transit improvements needed to accommodate . increased cumulative development. We strongly urge other local jurisdictions within the Tri-Valley to similarly address their responsibility for funding needed regional improvements. Cumulative Water Supply 3.6.4 Page 180 of the Draft EIR estimates the potable water demands of this project to be approximately 447,000 gallons per day, with an additional demand of 27,500 gallons per day for landscape irrigation, and 2,200 gallons per day of water demand for cooling of the on-site electrical generator. This represents a total water demand of 476,200 gallons per day. On page 181 of the Draft EIR, this water demand is identified as a less than significant impact based solely on a conversation between the EIR consultant and DSRSD staff. The Draft EIR presents no evidence to support the conclusion that "existing long-term contracts [are] in place to serve the full amount of development proposed...". In fact, the Draft EIR admits that the water demands of the project are nearly 2 ~ times the amount anticipated under the DSRSD Urban Water Management Plan. Mr. Michael Porto, Project Planner August 21, 2001 Page Four Current water supply contracts are based on numerous projections of demand, including projections contained in the Urban Water Management Plan. The water demands of the project substantially exceed the water demands contained in that Plan. It is unclear, therefore, how the Draft EIR can reach the conclusion that the water demands of the project would be a less than significant effect. We could assume that current water contracts could indeed supply the water needs of the project, had these needs matched the projections contained in the Urban Water Management Plan. However, the water demands of the project actually exceed the projections of the Water Master Plan by more than 262,000 gallons per day. How will this extra water demand be met? Will other cumulative development within DSRSD's jurisdiction be forced to rely on less supply than anticipated in the Water Management Plan in order to make up the difference? Will other customers within Zone 7's jurisdiction (i.e., the City of Livermore) be forced to do without their anticipated water supplies in order to accommodate this project's increased demand? The Draft EIR provides no analysis of this issue. The discussion of water'supply and demand contained in the Draft EIR is inadequate and does not provide adequate public disclosure of this potential effect. Recent litigation may further affect how, when, and how much water can be supplied to the project. Pursuant to a settlement of litigation concerning the provision of water to the Dougherty Valley project, DSRSD is required to initiate a new water service analysis. The results of this DSRSD study should have been used by this Draft EIR to assess the project's projected water demand, combined with cumulative water demands throughout the region. The Draft EIR should also have identified whether the project's water demand would exceed currently available water supply, and how water supplied to this project may affect water supplies to other cumulative development throughout the region. Additionally, the Draft EIR should have assessed the extent of environmental impacts that will be caused by the procurement of supply, conveyance, and storage capacity needed to meet this project's and other cumulative water demands, including the potential for increased seasonal storage facilities in the region. For the reasons cited above, the City of Livermore disagrees with the paragraph on page 181 of the Draft EIR that suggests the information contained in the Draft EIR fulfills the City of Dublin's responsibility under Government Code 65302.2. While the Urban Water Management Plan may be used as a Mr. Michael Porto, Project Planner August 21,2001 Page Five source document for such activities as amending the General Plan, it does not substitute for a well reasoned and researched analysis of potential project impacts on regional and cumulative water supply, as required in an adequate environmental review document. Jobs/Housing Page 122 of the Draft EI R shows the City of Dublin's current jobs/housing 3.6. ? imbalance, currently estimated at nearly two jobs per employed resident. Although a project-specific jobs/housing ratio is not included in the Draft EIR, one can estimate this effect using job projections and proposed housing opportunities. Assuming that the proposed 1,500 residential units would generate a total of approximately 2,250 employed residents, and using the Draft EIR's estimate of 7,832 jobs resulting from the project, the project's jobs/housing ratio is approximately 3.5:1. Although the Draft EI R recognizes that this project would contribute to Dublin's jobs/housing imbalance, it'does not consider this to be a significant effect. The Draft EIR presents no evidence to support this conclusion other than reference to the fact that this project is located along a major transit line. The City of Livermore disagrees with the Draft EIR's conclusion. Locating the project along a transit line does not fully address the physical effects associated with a Citywide jobs/housing imbalance. Since the local labor force will not be adequate in size to make up the employment generation projected for the project, future workers may still have to commute long distances to their jobs. The Draft EIR's estimate that 15 percent of the workers at the project will use transit (from page 146 of the Draft EIR) still leaves 85 percent of the workers arriving via automobile. These auto trips will continue to exacerbate regional air quality problems, add to existing congestion, and lead to a loss of community for cities that provide homes for these commuters. The Draft EIR does not present an alternative that would include an increased 3 proportion of housing opportunities within the project, such as an alternative that would have at least an on-site jobs/housing balance. The analysis of such an alternative might have shown that an even greater proportion of future employees could be dedved from the local labor force, thereby leading to further reductions in commute lengths, air quality emissions and traffic congestion. The continuation and worsening of the local jobs/housing balance will have significant environmental consequences not addressed in this Draft EIR. Mr. Michael Porto, Project Planner August 21,2001 Page Six Affordable Housing Opportunities Page 121 of the Draft EIR indicates ABAG housing goals for the City of Dublin, 3.6. ! 0 indicating a need for 1,327 affordable housing units from a total housing need of 5,436 units. This ABAG housing goal indicates a need for approximately 24 percent of all future housing to be made affordable to Iow- and very-low income households. The project proposes to "commit to meeting City affordable housing requirements within the residential area," and this commitment is considered a beneficial effect of the project (page 123 of the Draft EIR). However, under the current City of Dublin zoning ordinance, the affordable housing requirement is only 5 percent of the project total, or approximately 75 units. Given an actual demand for 24 percent of all housing units to be affordable to Iow- and-very Iow income households, the proportion of affordable housing units proposed in this project (5 percent) should not be considered beneficial overall. The Draft EIR (page 121 ) suggests that the City of Dublin Housing Element is planned to be updated in the near future to accommodate fair share housing targets. However, this EIR should include an accurate analysis of the effects of this project on the availability of affordable housing opportunities. Rather than considering the 5 percent commitment to affordable housing a beneficial effect, we believe that the EIR should conclude that the commitment of as few as 75 affordable housing units within a 1,500-unit project is a less than adequate contribution to the City's overall affordable housing need. Based on these comments, we believe that the Draft EI R should be revised and 3.6.1 ! re-circulated to provide an adequate and thorough analysis of these regionally significant issues affecting all jurisdictions within the Tri-Valley. Should you have any questions about these comments, please contact Ms. Susan Frost at (925) 373-5200. Again, we appreciate the opportunity to comment on this Draft EIR.

Box 2340 Dublin, CA. 94568 Re: Draft Environmental Impact Report PA 00-013 Dublin Transit Center Dear Mr. Porto: Zone 7 has reviewed the above-referenced CEQA.do~ument. The proposed project will consist of offices, high density residential dwellings, commercial retailing, and a parking garage and will be located on a. 91-acre 'site. Our comments below relate to Zone 7's responsibilities for water supply, flood protection, and groundwater management in the Livermore-Amador Valley. Reference should be made to our letter of December 8, 2000 to Mr. Eddie Peabody, Jr. regarding our response to the Notice of Preparation for this drat~ ElK. We have the following comments: 1. Page 93, Hydrology and Water ~Ouality, Environmental Setting, Water Quality 3.7.1 The draft ElK does not discuss the potential salt balance impacts to the main basin due to irrigating, landscape with .recycled water. Salt loading from this project development to the main basin is considered by Zone 7 to be "minimal to no" impact. Salt loading to Alameda County Water District (ACWD) should be mentioned as a potential impact. This impact is currently being addressed by a joint ACWD-DERWA study. 2. Page 95, Hydrology and Water Quality, Environment Impacts, Stormwater Runoff .3.7.2 a. The second paragraph mentioned that the development would generate approximately 47 acres of new impervious area. It should be noted that mitigation for impacts to flood control facilities downstream of the proposed project is handled through the collection of appropriate drainage fees for the Special Drainage Area 7-1 program. The 47 acres of impervious area would be subject to said drainage fees. Mr. Michael Porto AugUst 21, 2001 Page 2 b. In the 3ra paragraph, the effect of stormwater on Line G-5 is discussed at great 3.7.3 lengths; however, little is mentioned about the impacts on Line G-2 where Line G- 5 and the Caltrans box CUlvert drain into. A similar analysis for Lines G-1 and G-2 should be included. Adequate review cannot be made without seeing correct hydraulic assumptions. 3.

Zone 7's existing 24-inch Santa Rita-Dotigherty Pipeline, 1 g-inch Hopyard 3.7.5 Pipeline, 16-inch Santa Rita Pipeline, and DSRSD Turnout No. 4 appear to be within the project limits. These pipelines require planned maintenance in the future. Access needs to be maintained at all times to the turnout, valves and appurtenances. No structures nor trees will be allowed within the Zone 7 easements. An encroachment permit from Zone 7 will be required prior to any construction within a Zone 7 easement or in close proximity to Zone 7 facilities. Please submit future plans to Zone 7 for review as they become available. Please contact Athena Watson at (925) 484-2600, extension 243, regarding an encroachment permit or any other questions including specific facility locations. b. Zone 7 does not have any proposed transmission facilities adjacent to or within the 3.7.6 project Site/ c. Each April, since 1992, the Zone 7 staff has reviewed the Livermore Valley' s long- 3.7,7 term "sustainable ,;rater supply." There are several Zone 7 water supply numbers in the DEIR that should be updated. On page 173, State Water Project, 2~a paragraph, Zone 7's sustainable water supply is 84,100 acre-feet per year. On page 174, Local Surface Water, Lake Del Valle has a sustainable average yield of 9,300 acre-feet per year. The Anrrual Review of the Sustainable Water Supply, dated April 18, 2001, can be obtained from the Water Supply and Demand Section of Zone 7's home page.. The internet address is zone7water, com. Mr. Michael Porto August 21, 2001 Page 3 5. Page 180 and t81, Utili#es and Public Services, Environmental Setting, "Water Demand" a. The draf~ EZR should clearly identify both treated water and recycled water 3.7.8 demands for this project in the same five-year format as Table 26 on page 173. This information will be used by Zone 7 to update our water supply planning efforts and to plan future production facilities to meet the intermediate and long- term treated water demands in the Livermore-Amador Valley. Also, until the Salt Management Plan is implemented, this recycled water information will be used by Zone 7 to evaluate the potential impact to our main basin from each proposed development. b. We estimate an annual recycled water volume of 41 acre-feet based on the 3.7.9 assumptions given in the Draf~ EIR that 15 percent of the site is designated for landscaping and 36 inches of irrigation water is applied annually. This translates to a 36,600 gallons per day (gpd) annual average rate versus the reported 27,500 gpd estimate. Please clarify... We appreciate the opportunity to comment on this document.

KENNEDY ~ Di~TR,CT BART would like to thank the City of Dublin for this opportunity to Participate JAMES FANG in the public review process of the Draft Environmental Impact Report (DEIR) s~ D,sTRic, for the Dublin Transit Center. BART offers the following comments for your TOM RADULOVICH ~, D,s~,cT consideration. The East Dublin~Pleasanton BART Station that serves Dublin is at the heart of 3.8.1 the City's efforts to create a mixed-use transit-oriented center for development. One o.f BART's primary goals is to encourage the development of community- based plans that balance various opportunities and constraints associated with transit-supportive land use and enhanced access to BART. As such, BART supports the Dublin Transit Center proposal and has been working closely with the Alameda County Surplus Property Authority (Authority) and City of Dublin to ensure that the Center will enhance the BART station and the adjacent area. 'BART believes that the basic concept of replacing much of the existing surface parking with a parking garage will truly facilitate the "transit-oriented" development of the proposed project. This will greatly enhance access to and use of the BART station, and will also be an overall enhancement to the surrounding area. BAY AREA RAPID TRANSIT DISTRICT 800 Madison Street - Lake Metritt Station P.O. Box 12688 Oakland, CA 94604-2688 Telephone (510) 464-6000 As the DEIR correctly states, BART and the Authority have entered into an 3.8.2 agreement to allow for the replacement of existing surface parking with a parldng structure adjacent to the station entrance. As part of this agreement, the Authority recently constructed 421 spaces of short-term interim parking on County property adjacent to the station ("Site A"), with the understanding that Site A would be developed with housing once the parking structure is constructed. Construction of a 1,700 space, five-level BART parking garage will therefore allow for the replacement of the approximately 1,200 spaces currently located on "Site C", which then can be made available for mixed-use development. Additionally, the 1700 spaced garage will also replace the 421 temporary spaces. As noted in the DEIR, these 500 spaces in the new garage will therefore increase the supply of parking permanently available to BART patrons..It will not, however, increase the currently available supply, since the interim lot on Site A will be developed for housing in the future. Additionally, the currently ~permitted on street parking near the station will be lknited to short time periods as the area develops, thus reducing these parking spaces. Because the overall BART parking supply will not be increased by the 3.8.3 currently proposed garage, the BART/Authority agreement states that the garage will be designed to accommodate 250 additional spaces, so that these spaces can be added in the future if funding is available. Should funding become available for additional parking spaces, and to preserve the option for added parking~ BART recommends that the final EIR examine an alternative to the proposed project. This alternative would include a garage with up to 2,200- spaces, which would increase, the overall supply of BART parking spaces in Dublin by approximately 500 spaces over the existing number. This alternative should also consider possible impacts to nearby intersections and freeway congestion reduction benefits that up tO 500 additional space..s may b,ring. It should' be noted that the Final Supplemental Environmental Impact Report 3.8.4 (FSEIR) for the West Dublin/Pleasanton BART Station and Transit Village (April 2001) stated that BART is considering the implementation of a parking program at both the East and West DubliniPleasanton BART Stations, in which a patron can pay a fee of $2.00 per day on a monthly basis to guarantee 'a parking space until 10:00 a.m. Approximately one-half of the spaces at each station could be reserved on this basis, with the other one-half of the spaces remaining free on a fn:st come, fn'st served basis. This parking program should be incorporated by reference into the DEIR. In addition, the BART Board of Directors adopted a new parking limit policy 3.8.5 that will reduce a single parking event from 72 hours to 24 hours. This pot/cy will go into effect prior to the opening of the new extension service to the San Francisco International Airport, which is scheduled for Fall, 2002. At that time, M_r, Porto August 21, 2001 Page 2 BAYAREA RAPID TRANSIT DISTRICT 800 Madison Street - Lake Merritt Station p.O. Box 12688 Oakland, CA 94604-2688 Telephone (510) 464-6000 BART may have or BART anticipates that it will have parking char~s for long term and monthly parking at Selected stations. Since the East Dublin/Pleasanton Station is at the end of the line, it is reasonable to expect that this station will be targeted for these services. As stated in the West Dublin FSEIR, these parking policies may result in greater parking "spillover" if BART patrons seek nearby free parking are.as. While BART acknowledges that the Transit Center DEIR identifies spillover BART parking as a potentially significant impact, and proposes mitigation measures to mitigate these impacts, we suggest that additional mitigation measures be considered as well. For example, BART's Parking Management Toolkit developed for the BART San Francisco Airport Extension Project and referenced in the West'Dublin FSEIR, may provide appropriate mitigation measures. It appears that the 'proposed project may require the removal of a bus loading 3.8.6 area located adjacent to the proposed parking structure to enhance circulation and aesthetics of that portion of the site. This loading area serves Stockton Metro Area Regional Transit (SMART), Amtrak Thruway Bus, Modesto Transit, and CCCTA Route 259. While it appears possible to relocate the bus loading area to another part of the station area, we suggest that the Authority, the City of Dublin and BART work with the affected bus services to come up with an acceptable relocation plan that will not impact bus service.

Mr. Eddie Peabody Director of Community Development DUBUN PLANNING City of Dublin 100 Civic Plaza Dublin, CA 94568 ~ Letter 3.9 Subject: Dublin Transit Center Draft Dear Mr. Peabody: Thank you for forwarding a copy of the Dublin Transit Center Draft EIR which we have reviewed. As you are aware, we sent you a letter in December 2000 requesting that San Joaquin County be notified of any projects that have the potential of creating significant traffic impacts on Interstate 580 and the Altamont Pass. The Dublin Transit Center with its 2 million square feet of office space and 70,000 square feet of commercial space and up to 1500 apartments located immediately adjacent to 1-580 eertain!y has that potential. The Dublin Trangit center Draft EIR, however, dOes not addreSS cumulative traffiC' impacts 3.9.1 on 1-580 east 0f;Fallon Road. 'Specifically,' areas' of conCeim. regarding unaddressed potential cumulative traffic impacts include 1-580 from Fallon Road east over the Altamont Pass to 1-205 and also the Alameda and San Joaquin County access roads to 1-580 'in the vicinity of Altamont Pass including Grant Line Road, Altamont Pass Road and Byron Bethany Road. The f~eeway and county roads in these areas are already experiencing heavy congestion, and the Regional Transit Fees discussed as partial mitigation in the DEIR do not cover these roadways. In addition, Alameda County has been expressing its concern that all development in San 3.9.2 Joaquin County along 1-580 and 1-205 address cumulative traffic impacts to the above roadways. The residential development of concern in these areas has historically been associated with the imbalance of job growth and housing development in Alameda County and its neighboring counties which has led to heavy demand for housing in San Joaquin County. It appears that the office development proposed in the Dublin Transit Center will contribute to the jobs housing imbalance in Alameda County and continue to create more need for residential development in San Joaquin County. In order .for::the EIR:to adequately address cumulative traffic impacts, 'we specifically 3.9.3 request that the'FEIR'evaluate cumulative traffic impacts:to 1-'58'0 from Fall0n Road .east t° 1-205 and county access roads to 1-580 in the vicinity of Altamont Pass including Grant Line Road, Almmont Pass Road and Byron Bethany Road.[ In addition, the jobs housing 3.9.4 1 balance section of the EIR should identify where employees of the office buildings are likely to live given their household income levels and the local and regional supply of available, suitable housing as the project is occupied. This is of importance in evaluating regional cumulative traffic and homing demand impacts. Thank you for your attention to these matters.

It has been considered a model for other rail-trail projects around the stab and the country. First, we would like to commend the City of Dublin for its intent to der?lop the land surrounding the BAKT station as a high density transit oriented development. We applaud your efforts to reduce the number of auto trips that will be generated from this development, and especially your emphasis on buses, BART, and bicycle/pedestrian activity as the primary means oftranspor~ to and from the Center. The presence of the Iron Horse Trail, as well as providing the western boundary of the project, is a sig~xificant asset to the people who will work, shop, and commute through the transit village when it is completed. Rails-to-Trails Conservancy is a national nonprofit organization with an office and 8,000 members in California. We envision a country laced with a network o£trails, sidewalks, and on-street bike lanes that will enable people to travel within and between neighborhoods and cities by foot or bicycle. Numerous studies and the experience of hundreds of communities across the country demonstrate that such networks create big bang for the buck by serving real transportation needs. These facilities provide numerous additional benefits to local communities by creating landscaped open places for people to recreate and exercise. They also have tangible economic benefits to surrounding neighborhoods and community livability, particularly in terms enhanced property values and small business development. Completing this section of ' ' the Iron Horse Trail and connecting it to the planned TOD would bring these benefits C.,li[~n~i, Fi,la Ot{ice tO Dublin. 26 (YFm-rell Street Suite 400 San Francisco, CA 9~108 As the primary bicycle and pedestrian route the Diablo Valley, the Iron Horse Trail 4.1.1 n15.3~.~-2220 plays a crucial transportation and recreation role for the residents of Dublin and poJuts PAX: 415.397.2218 north.

The trail should connect directly with paths entering the development, and the ar~ should include plentiful bicycle parking, drinking fountains, b~nches, restrooms, gateway treatments at ~atrances, and parking for trail users arriving from outside of Dublin. Page 1 g6 of the DEIR., states that, "improvements pt~ned to consist of an unfenced 1 O-foot wide 4.1. paved trail within the existing right-of-way." We are concerned that 10 fe~t of width is not adequate rn accommodate the increased bicycle/skater/pedestrian traffic that the proposed development will generate. Although ten feet is the minimum multi-use trail width permitted by both Caltrans and AA. SI-ri'O, whenever greater use or a mix of modes is anticipated, a 12-foot path is recommended to avoid user conflicts. In some cases, a fourteen or sixteen foot wide path is warranted, although in this case, a 12-foot wide path with two foot wide decomposed granite . shoulders should be sufficient. In all respects, the design of the Iron Horse Trail and its support facilities should be consistent with best practlees in trail design, especially at intersections. Also of concern To us are comments on page 187 of the DEIR that state, "Implementation of the 4.1 · 3 proposed project would increase the demand for local and community park and recreation facilities for future residents within the Transit Center project; however, since the type of residential dwellings would not be primarily occupied by families with small children due to space constraints and (sic) adequate park and recreation facilities exist to the east, this impact is deemed less-than-significan'~' We are not sure why an assumption has been made that families with small children will not be interested in living in this new TOD. The benefits that TeD's offer, such as proximity to shopping, a village atmosphere, and transportation alternatives, are some of the most sought after elements of family housing. Unless this project proposes to actively discourage occupancy by families we believe this asstunption would be ha error. More problematic however, is the assumption that only small children require park and recreation facilities. In fact= people of all ages, including children, adults, and especially senior citizens require open space, hiking and biking trails, and playing fields iu order to lead a healthy lifestyle. The most recent public opinion and attitudes on outdoor recreation study, published by California State Parks in March 1998, determined that Californians believe outdoor recreation and facilities are very important to quality of life and that they want more local community parks mad places to ride and hike. The same study showed that walking ranked number one as the recreational activity most done by the state's citizens. We request that you update the DE[R to include provision of park and recreation facilities connected with an enhanced Iron Horse Trail as a required element of this development. Finally, we wan{ to encourage the City of Dublin to consider some additional enhancements that 4.1.4 would make the center a model for bicycle and pedestrian commuting. One of the most exciting kinds of projects underway in many cities is the development oi~ "Bikestation" within or very near transit centers. The Cities of Berkeley, Long Beach, and Pale Alto have opened Bikestations, and they have'become indispensable parts o£these communities' transport systems. See http://www.bikests.tion.or~ for more information. Thank you for your attention. Please contact us if we can be of further assistance. Master Response Regarding Cumulative Traffic Impacts and Traffic Impact Fees Several comment letters (Caltrans, City of Pleasanton, City of Livermore) raise issues with cumulative traffic issues of the proposed project and proposed mitigation measures. This section of the FEIR provides a response to these comments in a single location to reduce the length of individual responses. The City of Dublin has adopted a Traffic Impact Fee (TIF) Program for all properties located within the Eastern Dublin Specific Plan and General Plan area. TIF fees are collected on a square foot basis for all new development at the time building permits are issued for the purpose of constructing traffic and transportation improvements to accommodate cumulative traffic demand resulting from build-out of the Eastern Dublin Specific Plan and General Plan. The current Eastern Dublin TIF program includes numerous freeway improvement projects, including installation of eastbound/westbound auxiliary lanes on 1-580 between Fallon Road and Tassajara Road, and improvements to Hacienda Drive, Tassajara Road, Fallon Road and Airway Boulevard interchanges with 1-580. The TIF program also includes other improvements that directly benefit freeway operations, including park-and-ride lots and construction of Dublin Boulevard as a 6-lane arterial, which provides the only cross-valley parallel roadway and reliever route for 1-580. The City of Dublin also collects fees (Eastern Dublin 1-580 Interchange Fee) from all Eastern Dublin development projects to repay Pleasanton for existing improvements to freeway interchanges constructed by the City o£ Pleasanton. Properties encompassing the proposed Transit Center are not currently subject to TIF fees or the 1-580 interchange fee. However, since the Transit Center is proposed to be included in the Eastern Dublin Specific Plan, the TIF program is in process of being reviewed and may be amended to cover all future development within the project area, or a separate impact fee would established for the required improvements. As such, future development within the Transit Center would pay a £air share of transportation improvements as funded by the TIF Program. In addiQon, other traffic fees are earmarked for regional transportation improvements as part of the Tri-Valley Transportation Council (TVTC). These fees are known as the Tri-Valley Transportation Development (TVTD) fees and are collected from the various jurisdictions within the Tri-Valley area (including the cities of Dublin, Pleasanton, Livermore, San Ramon and Danville, and the Counties of Alameda and Contra Costa) and are intended to fund projects identified in the TVTC Strategic Expenditure Plan. A number of regional transportation improvement projects to be funded by TVTD fees include I- 580/Foothill Road-San Ramon Road interchange improvements, 1-680 auxiliary lanes between Bollinger Canyon Road and Diablo Road, West Dublin-Pleasanton Transit Center PA 00-013 Page 11 City of Dublin September 2002 BART station and HOV lanes on 1-580 from Tassajara Road to Vasco Road. The proposed project would be subject to the TVTC fee. The City of Dublin is also participating in the 1-580 Smart Corridor project which is being funded by the federal government. The Smart Corridor project involves computer-assisted freeway information infrastructure improvements, such as traffic monitoring and accident management, to maximize the use of vehicular capacity on the 1-580 freeway. The Smart Corridor project also includes identification of alternative reliever routes. Thus, although the Draft EIR identifies that mainline freeway operation impacts along the 1-580 freeway would be significant and unavoidable, the proposed Transit Center would be contributing fair share fees to assist in funding regional transportation improvements. The EIR identifies that major widenings and/or improvements to the 1-580 freeway would not be an economic or physically feasible mitigation measure that could be undertaken by the sponsors of the proposed project. Comment 1.1: Department of the Army · Comment 1.1.1: Clarification is needed regarding who will provide notifications for potential helicopter overflights of the project area. Sample notification language is provided for use by the City. Response: The suggested notification language is acknowledged. Mitigation Measure 4-9.3 is included in the EIR that would require future residents of dwelling units within the Transit Center project to be notified of potential helicopter overflight noise. Typically, such disclosures and notifications are required to be provided to future buyers and/or residents by the City of Dublin as part of subdivision map or Site Development Review (SDR) levels of land use entitlements. Comment 2.1: Caltrans · Comment 2.1.1: The commenter is concerned about the volume of additional traffic to the 1-580 freeway contributed by the project and disagrees with the DEIR finding that mitigation is not feasible. Caltrans urges the City of Dublin to participate in the development of funding mitigation measures. Response: The proposed Dublin Transit Center project would add approximately 10% (on average) to the AM and PM peak hour eastbound and westbound commute direction traffic on 1-580. These increases would be experienced on 1-580 west of the Dougherty/Hopyard interchange. East Transit Center PA 00-013 Page 12 City of Dublin , September 2002 of the 1-580/Dougherty-t-Iopyard interchange, project-related increases in peak hour commute traffic would be less than 10% depending on the freeway segment. The DEIR acknowledges that this would be a "significant and unavoidable impact." FIowever, this statement is not meant to imply that the City and/or project sponsor would not be assisting with funding solutions to regional traffic congestion as identified by Caltrans. Please refer to the Master Response regarding City of Dublin participation in freeway and freeway-related improvements. The Master Response notes that the City intends to include the proposed Transit Center project into the TIF prOgram, so that this project would contribute a fair share toward freeway-related improvements. The City of Dublin continues to believe that project-related impacts to mainline freeway operations will remain as significant and unavoidable even with the project's contribution to future improvements through payment of traffic impact fees. The City of Dublin notes that major project objectives include constructing a mixed-use, high-density transit village around a major transportation hub. These objectives are consistent with several recent "smart growth" development strategies recommended by regional planning agencies such as the Association of Bay Area Governments, Metropolitan Transportation Commission, Bay Area Air Quality Management District and others. As such, the proposed project would have a beneficial impact on regional commute patterns by placing higher density housing, . offices, retail and other land uses near convenient public transportation systems to reduce the number of single occupant vehicles on regional thoroughfares. · Comment 2.1.2: Caltrans recommends the following mitigation measures to control, monitor and improve traffic conditions: providing adequate storage for ramp metering queues, providing HOV by-pass lanes at metered on-ramps, installing closed-circuit television and other devices. Response: Comment regarding the need for mitigation of traffic congestion on the 1-580 freeway is acknowledged. Please refer to the Master Response. This response details the project's contribution of regional traffic impact fees and improvements presently and anticipated to be funded by these fees. The City of Dublin is also participating in the federally funded Smart Corridor project for the 1-580 freeway which includes many of the measures identified in the comment. Transit Center PA 00-013 Page 13 City of Dublin September 2002 · Comment 2.1.3: The commenter asks the relationship between 1-580 intersection improvements noted in the Transit Center DEIR (p. 167) and mitigation measures for the proposed Cisco Systems project. Response: Regarding mitigation measures for the proposed Cisco Systems project. This was a separate project located easterly of the proposed Transit Center. Cisco Systems withdrew its application to the City of Dublin for development of Site 15A in Eastern Dublin as an office complex. However, most recently, the Alameda County Surplus Property Authority has re- filed a Specific Plan Amendment and General Plan to re-designate Site 15A from High Density Residential to Campus Office. A specific user for Site 15A has not been identified. The City of Dublin is currently evaluating anticipated traffic impacts of the proposed Specific Plan and General Plan Amendment request. · Comment 2.1.4: Mitigation measures at the Dougherty Road/1-580 and Hacienda Drive/I-580 interchanges involving on-ramps need to include the ramp metering system and the HOV bypass lane. Response: Project specific traffic mitigations for Dougherty Road/I-580 and Hacienda Dr./I-580 interchanges have been recommended in the DEIR. Project specific mitigation required for the Dougherty/I-580 interchange would involve widening/re-striping of southbound Dougherty Road between Dublin Boulevard and the 1-580 westbound off-ramp as well as widening and re-striping the 1-580 westbound diagonal on-ramp as described on page 167 of the DEIR (also see Response 3.5.7). The widening of this on-ramp will be coordinated with Caltrans to satisfy HOV bypass lane requirements. With respect to the Hacienda/I-580 interchange, modifications have been recommended in the DEIR, page 167 (Mitigation Measure 4.11-1) for the westbound loop on-ramp with project traffic. These modifications will be coordinated with Caltrans to satisfy HOV bypass lane requirements. It is recognized that ramp metering and HOV bypass lanes may improve traffic flows to/from 1-580 on a system-wide basis. The Dublin City Council adopted Resolution No. 168 in 2001 supporting the phased implementation of ramp metering on 1-580 from 1-880 to the Altamont Pass. The implementation plan of ramp metering along 1-580 will be devised as part of the next phase of the 1-580 Smart Corridor project which will also fund the installation of Intelligent Transportation System (ITS) components for system-wide ramp metering along 1-580. Transit Center PA 00-013 Page 14 City of Dublin September 2002 · Comment 2.1.5: Year 2025 forecast for 1-580 mainline operations show minimal project traffic for the peak commute directions (westbound AM and eastbound PM). The commenter recommends a closer study of this situation. Response: Regarding future traffic on mainline 1-580 freeway operations, the proposed project would be contributing (on average) 10% or less to peak commute directions on 1-580 mainline segments. This is identified in the DF. IR as a significant and unavoidable impact (Impact 4.11-7). Project- related peak hour trip generation and trip distribution has been reviewed by the City of Dublin and no additional study is warranted for this project. The City of Dublin will continue to monitor future development projects for contribution of traffic to the 1-580 freeway. · Comment 2.1.6: The project site is less than one mile from the 1-580/I-680 interchange. Please discuss the impacts to the 1-680 freeway. Response: Based on information developed subsequent to circulation of the Draft EIR for this project, new information has been developed that indicates a potentially significant and unmitigatable impact to mainline 1- 680 freeway operations would result with the development of the proposed Transit Center. Therefore, as previously described in this document, this new impact has been re-circulated for a 45-day period and responses are incorporated in the Introduction section of this document. · Comment 2.1.7: The commenter emphasizes the Transit Center DEIR should not ignore the significant impacts that occur with project implementation, including those impacts outside of its jurisdiction. Response: Comment acknowledged regarding potential project impacts to traffic on nearby freeways. Please refer to the Master Response regarding the proposed project's contribution to regional transportation improvements and the above responses regarding freeway impacts. · Comment 2.1.8: The commenter believes that feasible mitigation measures will lessen the impact on State transportation facilities. The DEIR should quantify impacts and develop measures to mitigate those impacts and incorporate those measures in a Final EIR. Response: The City of Dublin shares the Caltrans concern for minimizing the proposed projects impacts; as shown in Table 25 of the DEER, 1-580 freeway is anticipated to operate at unacceptable levels of service during Transit Center PA 00-013 Page 15 City of Dublin September 2002 peak hours whether or not the proposed Transit Center is constructed. The analysis suggested by Caltrans is already present in the DEIR (reference DEIR Impact 4.11-7). On page 166, the DEIR text notes that mitigation measures include payment of regional impact fees. The proposed Transit Center would-make a contribution to assist in funding improvements for regional State facilities (see the Master Response). However, even with the identified mitigation measures, mainline conditions would exceed thresholds of significance set forth in the DEIR. Nevertheless, the Transit Center would be required to participate in regional impact fee programs and the City has agreed to participate in the 1-580 Smart Corridor program. Through the DEIR analysis and the above described measures, the City recognizes freeway conditions and continues to work on both a project and regional level to reduce traffic impacts. Comment 2.2: State Office of Planning and Research (OPR) · Comment: State Clearinghouse has received the DEIR and submitted the document to selected state agencies for review. Response: Comment acknowledged regarding completion of the 'public period. No further discussion is required. Comment 2.3: State Department of Fish and Game · Comment 2.3.1: Information contained in the DEIR is based primarily on previous studies completed by Jones & Stokes and H.T. Harvey Associates. Response: A number of studies of properties in the general vicinity of the Transit Center site were reviewed for the possible presence of species. Focused surveys have also been recently conducted on the site by Davis Environmental Consulting. The first of these surveys was conducted in the spring of 2001. An additional late season survey was conducted in August 2001 to cover the growing season of late-blooming plants but has not yet been published. Along with the previous studies completed by Jones & Stokes and Harvey Associates, these studies provide a comprehensive background for biological resources on the project site. · Comment 2.3.2: California tiger salamanders have been documented on at Camp Parks, immediately north of the project site and the Department does not agree with the finding that the site is not suitable for this species, even with historic disking of the site. Transit Center PA 00-013 Page 16 City of Dublin September 2002 · Response: The potential presence of Califomia tiger salamander species was addressed on pp 65-66 of the DEER. No new California Tiger Salamander surveys were conducted during the reconnaissance survey of the site, however, the site was surveyed for California tiger salamanders during 1994-1995. The survey was conducted for BART and covered the same area currently under consideration for the Dublin Transit Center. In the 1994-1995 survey, both nocturnal, visual surveys for adults and dipnetting surveys for larvae were conducted on the project site. Nocturnal surveys were conducted during rainy nights between November 1994 and January 1995. Larval dipnet surveys were conducted in May' 1995. Each field visit to the project site was complemented by a field visit to a known reference site on the same night or day. Nocturnal surveys entailed 10 field visits during which roads around the project site were driven and transects were walked throughout the site. During the 10 nighttime surveys, no California tiger salamanders were observed on the Transit Center site. California tiger salamanders were observed at the reference sites during 9 of the 10 nocturnal field visits, indicating that California tiger salamanders were active and above ground at the time of the surveys, and that environmental conditions were appropriate to observe California tiger salamanders on the project site had they been present. Similarly, no California tiger salamander larvae were observed in any of the aquatic habitats on the project site (ditches and ponds), while California tiger salamander larvae were observed at the ponds on reference sites on the same days. The report concluded that California tiger salamanders did not occur on or near the site. Since the 1995 report to BART, the BART parking lot has been constructed on the project site and additional development has occurred in the vicinity of the Transit Center site, essentially isolating the site from suitable estivation and breeding habitat that occur north and east of the project site. Habitat fragmentation is an issue for California tiger salamander populations in the Bay Area, but this site is already isolated by other development in the area, particularly the extensive residential and commercial development to the east. In light of the 1995 survey results, the ongoing disturbed condition of the site, its isolation from other natural open space areas, and the lack of suitable breeding ponds onsite, the site does not currently provide habitat for California tiger salamander. As an isolated parcel, development here would not increase fragmentation. Other developments in the East Dublin area have already fragmented the California tiger salamander habitat in the region and development of this parcel, which is already surrounded by development, will not contribute to further fragmentation of the California tiger salamander habitat in the Eastern Dublin area. Thus, no further analysis is required under CEQA. Transit Center PA 00-013 Page 17 City of Dublin September 2002 · Comment 2.3.3: The Department considers the mitigation measure proposed in the DEIR inadequate regarding burrowing owl species. Surveys should be conducted within the project area and a 500-ft. zone around the project. Response: As noted on page 71 of the DEIR, no burrowing owls or burrowing owl signs were observed on the site during reconnaissance surveys completed by the project biologist. However, it is noted that this species is known from the area and it could potentially occur on the site. In response to the Department's comment, the following substitute mitigation measure language is proposed for Mitigation Measure 4.3-3 (a) and (b): · Pre-construction surveys by a qualified biologist shall be conducted on the entire Project area and within 150 meters (500 feet) of the Project area within 30 days prior to any ground disturbance. If ground disturbance is delayed or suspended for more than 30 days after the pre-construction survey, the site shall be resurveyed. · If over-wintering birds are present (September I to January 31) no disturbance should occur within 160 feet of occupied burrows unless the Department of Fish and Game provides a letter giving consent to relocate wintering birds. If owls must be moved away from the disturbance area, passive relocation techniques, following CDFG 1995 guidelines, should be used rather than trapping. If no over- wintering birds are observed, burrows may be removed prior to the nesting season to reduce impacts from noise, dust, and human disturbance to mated pairs. · If removal of unoccupied potential nesting burrows prior to the nesting season is infeasible and construction must occur within the breeding season, maintain a minimum buffer (at least 250 feet) around active burrowing owl nesting sites identified by pre- construction surveys during the breeding season to avoid direct loss of individuals (February I - September 1). All active burrows shall be identified. · If construction is scheduled during summer, when young are not yet fledged, a 250-foot exclusion zone around the nest shall be established or construction shall be delayed until after the young have fledged, typically by August 31. Transit Center PA 00-013 Page 18 City of Dublin September 2002 · When removal of occupied burrows is unavoidable, existing unsuitable burrows should be enhanced (enlarged or cleared of debris) or new burrows created (by installing artificial burrows) at a 2:1 ratio on protected lands, as provided for below. · A minimum of 6.5 acres of foraging habitat per pair or unpaired resident bird, shall be acquired and permanently protected. The protected lands shall be adjacent to occupied burrowing owl habitat and at a location acceptable to CDFG. · The project proponent shall prepare a management plan and provide funding for long-term management and monitoring of the protected lands. The monitoring plan should include success criteria, remedial measures, and an annual report to CDFG. · Comment 2.3.4: The Department does not concur with the DEIR finding that kit fox are absent from the site. Response: The absence of kit fox on the project site is documented on pp 69-70 and in Table 8b of the DEIR. Ruderal grassland such as that found on the Transit Center site may provide foraging habitat for kit foxes; however, the isolation of this site from large tracts of open grasslands makes it unlikely that it is used by this species. The project area is too small to sustain a viable kit fox population and too isolated to be an important foraging area. Given that this species occurs in low numbers in this portion of the range, it is even less likely that an isolated parcel such as the Transit Center site, surrounded by development and major roadways on all sides, would be used on a regular basis. Because the site is at the edge of kit fox range, implementation of pre-construction surveys would be appropriate to avoid any "take" of kit foxes due to mortality or harassment. However, the poor quality of the site as foraging and denning habitat does x~ot warrant compensatory mitigation for this species. The project will implement protection measures for San Joaquin Kit Foxes as required by the East Dublin Specific Plan. This includes pre-construction surveys of the site prior to habitat modification. A copy of the Kit Fox Protection Plan is available for review at the City of Dublin Planning Division office during normal business hours. · Comment 2.3.5: A thorough field survey for Congdon's tarplant is needed to determine the extent of these species on the project site. The Department recommends avoidance of populations of these species. If Transit Center PA 00-013 Page 19 City of Dublin September 2002 avoidance is not possible, the Deparhnent does not recommend tTanslocaQon of seeds, since this may not be successfi~l. Response: Potentially significam impacts of the proposed project on Congdon's tarplant is identified in the DEIR as Impact 4.3-1. This is the one species that was observed on the site during the field survey and Mitigation Measure 4.3-1 has been proposed to reduce impacts to this species to a less-than-significant level. Avoidance of this species has been deemed infeasible within the project area due to the project's design as a higher intensity, mixed-use transit-oriented project across the entire site. Collection and planting of seed is not acceptable mitigation to the Department, therefore the only remaining feasible mitigation measure for impacts to this species is preservation of off-site populations. Based on the Department's comment, the following substitute Mitigation Measure 4.3-1 is proposed: The size of the area occupied by the tarplant should be determined from the field survey and notes on past on-site distribution, measuring the entire area from which the plant has been observed. If on-site avoidance is not possible, one of the following options must be taken to ensure replacement on a 1:1 acreage ratio: a. Permanently preserve, through use of a conservation easement or other similar method, equal amount of off-site acreage that contains the plant; or b. Harvest seeds from on-site plants to be lost or from another source within the Livermore-Amador Valley, and seed an equal amount of off-site area suitable for supporting the plant which shall be preserved and protected in perpetuity. Prior to submittal of a Site Development Review (SDR) application for a specific development site, the project developer shall submit a Mitigation and Monitoring plan to the City for its review and approval, demonstrating how the developer will comply with this mitigation measure, including the steps they will take to ensure that reseeding will be successful. If Option" b' is selected and is not successful, Option "a' shall be implemented. Contrary to the commenter's assertions, the DEIR's programmatic analysis, together with the modified mitigation measure (above) is adequate under CEQA. The DEIR discusses that the species is known to be present and will be affected by future development of the proposed Transit Center. Feasible mitigation measures are identified to preserve the species through off-site mitigation. The mitigation measures further provide for refinement of Transit Center PA 00-013 Page 20 City of Dublin September 2002 off-site protection programs prior to the approval of any subsequent approval of development projects. · Comment 2.3.6: The project should result in no net loss of either wetland acreage or wetland habitat. Previous creation of wetland related to the on- site BART facility in 1995 have not functioned properly. Response: The potential for both wetland acreage and habitat occurring on the site was addressed in the Environmental Setting Section of the Biological Resources section of the DEIR. A jurisdictional determination for the project area was updated on June 5, 2001. No jurisdictional waters of the U.S. are contained within the Transit Center area (Corps File # 25892S). Ditches and drainages that surround the site are not included in the project area and there is no plan to fill these features as part of this project. If wetlands created as compensatory mitigation for the previous fill of 2.88 acres are not functioning properly, then it is the responsibility of the Corps and agencies with permitting authority to seek remedial action at these created wetlands from the responsible party (BART) in order to have them meet the criteria established in the wetland mitigation and restoration plan. The project area as it currently exists does not have any jurisdictional features. Previous fills were completed under the appropriate permits from the Corps and no wetlands occur onsite. Because this project does not fill any wetlands, there will be no net loss of wetlands due to this project and therefore no mitigation for wetland fills is required. · Comment 2.3.7: A Streambed Alteration Agreement must be obtained for any work in a lake or stream corridor. · Response: Streams and ditches that surround the site are not part of the project area and no work is to be conducted in these ditches as part of the Transit Center project. Therefore, no Streambed Alteration Agreement will be required from the Department for this project. Comment 3.1: Alameda County Public Works Department · Comment 3.1.1: The introduction of "outside traffic" may develop an imbalance with a greater demand for on-street parking than what is physically available. A transit system and satellite parking lots should be Transit Center PA 00-013 Page 21 City of Dublin September 2002 explored connected to the BART system along with other parking improvements. Response: The installation of street limited-time parking and permit parking are part of the overall parking strategies surrounding the proposed BART parking structure discussed in the Transit Center DEIR on pages 155 and 156. In order to provide additional parking beyond the 1,680- 1,700 spaces analyzed in the DEIR, BART is exploring the possibility of adding 500 parking spaces to the proposed parking structure (for a total of 2,200 spaces) which would provide relief &om excess on-street parking demand in the vicinity. Please refer to Response 3.8.3 in the FEIR for additional discussion and analysis regarding the potential provision of additional BART parking. Comment 3.2: Alameda County Congestion Management Agency · Comment 3.2.1: Project impacts to MTS routes must be analyzed in the environmental document: 1-680, San Ramon Road, and Foothill Road. Response: The following responds to CMA's request for additional information regarding impacts to MTS routes. For 1-680, please refer to response 2.1.6 (Caltrans). MTS routes of San Ramon Road and Foothill Road have been analyzed for project impacts as part of this FEIR. Based on overall project trip distributions found in the DEIR, it is projected that of the project trips to/from the west, 1% would use Footkill Road and 3% would use San Ramon Road via Dublin Boulevard. During the AM peak hour, this would equate to 41 trips on Foothill Road and 123 trips on San Ramon Road. Vehicle trips on San Ramon Road would likely use Dublin Boulevard or Amador Valley Boulevard to access the project site to/from the west. This would further serve to disperse the 123 trips on San Ramon Road. For these reasons, proposed project trips would not change roadway LOS listed for San Ramon Road and Foothill Road on these MTS routes from Year 2005 or 2025 levels as listed in the ACCMA CMP. Comment 3.2.2: The DEIR states that the Countywide Model was not used to analyze project impacts to the MTS system for 2005 and 2025. A comparison of traffic volumes between the Countywide model and the model used in the DEIR must be included in the FEIR. Response: The ACCMA Countywide model was not used for future horizon Years 2005 and 2025. In its place, the Tri-Valley Transportation Model was used. Discussions with ACCMA staff resulted in the use of the Tri-Valley model rather than the ACCMA Countywide model for future Transit Center PA 00-013 Page 22 City of Dublin September 2002 projections. As requested by CMA staff, the Tri-Valley model volumes were compared to the ACCMA Countywide model volumes to assure that the most conservative volume projections were applied in the DEIR. The Tri-Valley model's land use assumptions were based on ABAG Projections '98 data and the street network was updated using the recent Alamo Creek Transportation Model for the Dublin/Pleasanton area. Consistent with ' ACCMA guidelines and discussions with ACCMA staff, the FEIR compares PM peak hour link volumes between the Countywide model and Tri-Valley model to show that the most conservative model volumes have been used for the project analysis. PM peak hour (two-way) link volumes on the MTS roadways of Dougherty Road, Dublin Boulevard, and Tassajara Road from the DEIR have been compared to ACCMA model output in Table 2, below. Table 2. Comparison of ACCMA Model and Tri-Valley Model PM Peak Hour Two-Way Link Volumes 2005 ACCMA/Tri-Valle¥ 2025 ACCMA/Tri-Valley Dougherty Rd.: n/o Dublin Blvd. 2,945/4132 3,817/4,642 Dublin Blvd.: Dublin to Arnold 2,223/4,662 4,421/4,830 Arnold to Hacienda 843/3,716 2,313/4,085 Tassajara Road: 1-580 to Central 2,369/4,677 4,034/5,352 (1) Dowling Associates, "Dublin Transit 2025 Land Use Projections '98," November 15, 2000. (2) Alameda County Congestion management Agency, "ACCMA Projections '98-2005 and 2020 Base Model, October 14, 1999. As shown in Table 2, the Dougherty Road, Dublin Boulevard, and Tassajara Road MTS roadway segments would experience higher volumes with the Tri-Valley Model used in the DEIR. This would apply to both the 2005 and 2025 horizon years. A review of other MTS roadways indicates that this trend would hold true for other segments outside the study area. Therefore, Tri-Valley Model projections for the Year 2005 and 2025 were used rather than the ACCMA Countywide Model for the most conservative cumulative analysis. Discussions with ACCMA staff confirm that the Tri-Valley Model projections are acceptable for this EIR. · Comment 3.2.3: The Congestion Management Agency does not have a policy for determining a threshold of environmental significance. It is expected that professional judgment will be applied to determine project level impacts. Transit Center PA 00-013 Page 23 City of Dublin September 2002 Response: It is acknowledged that ACCMA does not have a policy for determining a threshold of significance. Reference to CMA significance criteria has been removed by reference from the DEIR text. This is further documented in the Clarifications and Modifications section of the FEIR (see Modification No. 5). However, the ACCMA standards, established for the purpose of monitoring existing LOS conditions on the Alameda County CMP Designated Roadway System, are still used in this FEIR as standards of significance based on professional judgment. Traffic and circulation impacts and mitigation measures pursuant to CEQA will not change. · Comment 3.2.4: The DEIR states that BART assumes a ridership load capacity of 1.35 per train during peak hour commutes. The CMP only assumes this factor when to average peak hour, peak transbay load factors for all 4 BART routes. A load factor of 1.15 is generally used at other times. BART ridership factors should be verified by BART staff. Response: The ridership or load factor of 1.35 per train was provided by BART staff for this analysis and is consistent with observed BART ridership during peak hour commute periods. According to BART staff, this load factor allows for riders in the seats as well as standing in the aisles as discussed and referenced on page 153 and 154 in the DEIR. It is acknowledged that a load factor of 1.15 may be used during off-peak periods when BART ridership is not at its peak. However, BART staff recommended a load factor of 1.35 for peak hour analyses. · Comment 3.2.5: For CMP purposes, the roadway network used to analyze project impacts on the MTS must be consistent with the 2005 CMP Capital Improvement Program and 2025 CWTP Investment Program. Improvements assumed in the base networks must have full funding identified. Response: The roadway network used to analyze project impacts is consistent with the 2005 CMP CIP and. the 2025 CWTP Investment Program. Based on discussions with City of Dublin Transportation staff, network improvements listed on pages 157 and 158 of DEIR would be funded by the Eastern Dublin TIF, the TVTD fee program, the Dougherty Valley Development Dublin-Contra Costa fees, and project-specific improvements including the traffic mitigations listed in the DEIR for the proposed Transit Center Development. Transit Center PA 00-013 Page 24 City of Dublin September 2002 · Comment 3.2.6: If this project is subject to the TVTD traffic mitigation fee, it should be acknowledged in this section. For CMP purposes, project contribution toward a fee to mitigate regional transportation impacts counts toward project mitigation. Response: The proposed Dublin Transit Center would be subject to and would contribute towards the TVTD traffic mitigation fee should the project be approved. Comment 3.3: Dublin San Ramon Services District · Comment 3.3.1: Estimated water demand for the buildout of the proposed project is estimated to be 447,000 gallons per day. Preliminary planning by the City of Dublin and DSRSD has reserved 185,000 gallons per day for this project, however, facilities currently planned by DSRSD will be of sufficient capacity to serve the proposed project. Use of recycled water and adherence to standard water conservation measures may reduce the total anticipated estimated water demand. No mitigation is needed. Response: Comment acknowledged that DSRSD has determined that sufficient water supplies will exist to serve the buildout of the proposed Transit Center. DSRSD recommends no additional mitigation measures regarding potable water supply and service to serve the proposed project. · Comment 3.3.2: The DEIR notes that the project would result in an expected demand for 27,500 gallons per day for recycled water and 2,200 gallons per day for electrical generation cooling purposes. There would be a shortfall of 23.3 acre-feet per year of recycled water above what is currently reserved to serve the project. This shortfall will be mitigated by planned upgrades to DSRSD's Recycled Water Reclamation Plant. Response: Comment acknowledged that short-term recycled water supplies are available to serve the proposed project and that long-term demand will be met through planned upgrades of the recycled water system. · Comment 3.3.3:The proposed project would generate an estimated 447,000 gallons per day of wastewater at full buildout. This amount of wastewater has been included in DSRSD's and LAVWMA's wastewater facility planning and no additional mitigation is needed. Transit Center PA 00-013 Page 25 City of Dublin September 2002 Response: Comment acknowledged that the planned expansion of DSRSD and LAVWMA's wastewater collection, treatment and disposal systems will be adequate to serve the project. · Comment 3.3.4: No mitigation for the project beyond that specified in the DEIR for water, recycled water or wastewater is needed. Response: Comment acknowledged that that the Draft EIR adequately addresses potable water, recycled water and wastewater collection, treatment and disposal and no additional mitigation measures are needed. Comment 3.4.1: East Bay Regional Park District · Comment 3.4.1: Connections of the Iron Horse Trail to multi-modal transit stations are a goal of the District. The District is supportive of the proposed project which promotes public transit alternatives to automobile travel. Response: Comment acknowledged regarding background information regarding the Iron Horse Trail, which is located immediately to the east of the proposed Transit Center site, and the East Bay Park District's support of project objectives. No further analysis is needed regarding this comment. · Comment 3.4.2: The DEIR notes that the proposed project would reduce existing views of Mt. Diablo and other nearby ridgelines from some viewpoints. The District recommends that that the Trail not be blocked off by buildings or walls. Response: Impact 4.1-2 identifies potential blockage of views from the Iron Horse Trail to adjacent foothills and open space. Adherence to Mitigation Measure 4.1-1 would ensure that some views from the Trail would be maintained, as identified through the Site Development Review (SDR) process. This Mitigation Measure encourages the reservation of view corridors through the project to maximize views to surrounding features. · Comment 3.4.3: Impact 4.13-2 of the DEIR notes that construction of the project would have a less-than-significant impact on parks and recreational facilities. The District notes that construction of the residential component would increase demand for regional facilities, such as the Iron Horse Trail, and encourages complementary bicycle and pedestrian facilities and use of impact fee funds. Transit Center PA 00-013 Page 26 City of Dublin September 2002 Response: Construction of the residential component of the proposed Transit Center is anticipated to increase the use of local, community and regional recreational facilities. The City has planned for local and community parks to serve new developments. As noted on p. 187 of the DEIR, the Iron Horse Trail has long been planned as a major regional facility. Multi-modal transportation as well as connections to the Iron Horse Trail are addressed in the project and would further be refined in further implementing development projects. There would also be impact fees, property tax revenues and other sources of funding to assist in constructi°n and maintenance of recreational facilities. · Comment 3.4.4: Staging and parking areas for trail users should be considered as part of the project, which could include dedicated parking areas and shared use of parking facilities during non-peak times. Response: The possibility of including staging and parking areas for the Iron Horse Trail is not precluded in the EIR. These proposals will be considered as part of more specific Stage 2 Planned Development applications to be considered by the City of Dublin. · Comment 3.4.5: Bicycle facilities, including but not limited to bike parking, signal standards, and related features should be included within the proposed project. Response: East Bay Regional Park District's comments and recommendations regarding inclusion of bicycle facilities within future Transit Center development projects are acknowledged. The application for the project filed by the Alameda County Surplus Property Authority identifies as an objective of the proposed project "to create safe and convenient pedestrian/bicycle connections between local destinations, transit stops and nearby regional trails." (Dublin Transit Center, General Plan/Specific Plan Amendment and Stage 1 Planned Development Rezoning, Alameda County Surplus Property Authority, 9/01). Specific designs and locations of these connections will be identified through the Site Development Review process as specific development plans are filed with the City of Dublin within the Transit Center project area. Comment 3.5: City of Pleasanton · Comment 3.5.1: The City of Pleasanton would like to review specific traffic impact fees that would be collected by the City of Dublin to determine if such fees are adequate to finance needed transportation infrastructure. Transit Center PA 00-013 Page 27 City of Dublin September 2002 Proposed interchange and intersection improvement projects need to be adequate to accommodate proposed project traffic so traffic does not "spill over" into Pleasanton. Response: As indicated in the Master Response, the current Eastern Dublin TIF program includes numerous freeway improvement projects, including installation of eastbound/westbound auxiliary lanes on 1-580 between Fallon Road and Tassajara Road, and improvements to Hacienda Drive, Tassajara Road, Fallon Road and Airway Boulevard interchanges with 1-580. The TIF program also includes other improvements that directly benefit freeway operations and help reduce traffic congestion in the City of Pleasanton, including park-and-ride lots and construction of Dublin Boulevard as a 6-lane arterial, which provides the only cross-valley parallel roadway and reliever route for 1-580. The City of Dublin also collects fees from all Eastern Dublin development projects to repay Pleasanton for existing improvements to freeway interchanges. The Eastern Dublin TIF program was last updated in 1999, and the current fee amounts are based on the cost estimates calculated in 1999 for these freeway-related improvements. Properties encompassing the proposed Transit Center are not currently subject to TIF fees. However, since the Transit Center is proposed to be included in the Eastern Dublin Specific Plan, the TIF program is in process of being updated and will likely cover all future development within the project area. This TIF update will also include updating the cost estimates for the above freeway-related improvements. Future development within the Transit Center would pay a fair share of regional transportation improvements as funded by the TIF Program. In addition, one of the mitigation measures specified in the DEIR for the Transit Center development is the widening of the Hacienda Drive overcrossing in the northbound direction to include three through lanes and an exclusive right-turn lane leading to the 1-580 westbound loop on- ramp. This mitigation measure is intended to prevent northbound traffic on Hacienda Drive from spilling over into the City of Pleasanton during the AM peak period under future traffic conditions with Transit Center traffic. · Comment 3.5.2: Trip generation assumptions used as the basis of the traffic analysis are substantially less than used by the City of Pleasanton and may understate traffic conditions. Response: Trip generation assumptions for the proposed project were reviewed at length by City of Dublin Transportation staff as part of the EIR Transit Center PA 00-013 Page 28 City of Dublin September 2002 process. In addition, a review of other office trip generation was conducted for other office development around existing BART stations and is shown in Table 3. As shown, the office trip generation rates used for the proposed Dublin Transit Center are actually higher than those used by the City of Pleasanton. It is true that Pleasanton's rates are 1.33 trips/I,000 square feet for the AM and PM peak hour. However, these rates were reduced by 15% due to their proximity to the planned West Dublin/Pleasanton BART Station and Transit Village Development. This is evidenced in the trip generation conducted for the Pleasanton portion of the West Dublin/Pleasanton BART development. Office uses for the Pleasanton portion were calculated using an AM and PM peak hour rate of 1.13 trips/I,000 square feet. With respect to residential development, AM and PM peak hour rates used for the proposed project were reduced by 25%. This is consistent with residential trip rates for the planned West Dublin/Pleasanton BART Station and Transit Village, which were reduced by 30%. Peak hour rates used for the project's retail development are based on ITE research for specialty retail development. The projected retail uses are planned to be ancillary to Transit Center office development and serve the internal office populations. None of the retail is expected to be "destination" oriented and it would not generate the same number of vehicle trips as other typical retail-commercial development. Table 3.

Since the amount of surface parking spaces is to be eliminated, there will be a loss of BART parking and this should be disclosed in the DEIR. Response: The proposed development of the Transit Center would eliminate surface parking spaces, but these would be replaced in the proposed on-site parking garage. The proposed project would therefore not preclude future increases in the number of BART parking spaces. BART is currently studying the possibility of adding 500 new parking spaces to the prOPosed parking structure in addition to the spaces currently on the site. Please see the comment letter from BART (Letter 3.8) and the response, which indicates that the addition of 500 BART parking spaces would not result in a significant impact to'local streets and intersections during peak hour conditions. * Comment 3.5.4: The DEIR notes problems at Dublin Boulevard and Dougherty Road (LOS E in the AM and F in the PM). These conditions would influence traffic operations at Dougherty Road and Westbound 1- 580 ramps and Hopyard and eastbound 1-580 ramps. Improvements to upgrade these conditions may not be funded as part of the short-term CIP program. Response: Regarding anticipated impacts to the Dublin/Dougherty and other intersections, with Year 2005 existing plus future base conditions, one intersection is expected to operate at poor levels. The Dougherty/Dublin intersection would be operating at LOS E (0.94) during the AM peak hour and LOS F (1.03) during the PM peak hour. In addition to mitigation measures recommended for the eastbound/westbound Dublin Boulevard approaches, mitigation .is also recommended for the Dougherty Road northbound/southbound approaches that would include widening and lane re-striping (please refer to DEIR, page 141). With these mitigation measures, intersection LOS is projected to improve to LOS C (0.73) during the AM peak hour and LOS D (0.85) during the PM peak Transit Center PA 00-013 Page 30 City of Dublin September 2002 hour. With these improvements to northbound Dougherty Road, significant vehicle queuing is not anticipated along Dougherty Road at the 1-580 westbound and eastbound (t-Iopyard) intersections. The current CIP program for the City of Dublin includes a Dougherty Road improvement project between Houston Place and 1-580 to be funded in part by the Eastern Dublin TIF program. This CIP project includes intersection improvements at Dougherty Road/Dublin Boulevard as specified in the TIF program. Construction of this CIP project is currently scheduled for Fiscal Year 2003-2004. The commenter may refer to pages 141 and 144 of the DEIR for a description of improvements covered by this CIP project at the Dougherty Road/Dublin Boulevard intersection under future base conditions. · Comment 3.5.5: The DEIR notes several problem areas under Cumulative Year 2025 With Project condition, the most significant being the Dublin Blvd./D°ugherty Road intersection. Future daily traffic volumes are anticipated to double from 40,000 to 80,000 vehicles. Response: Cumulative Year 2025 with Project volumes would significantly impact the Dougherty/Dublin intersection. Average daily traffic volumes would increase between 1-580 and Dublin Boulevard on Dougherty Road causing significant congestion at the Dougherty/Dublin intersection as identified in Impact 4.11.5 in the Draft EIR. Mitigations are proposed to the Dublin/Dougherty intersection (see Mitigation Measure 4.11-1), however, even with mitigation, cumulative traffic conditions in the year 2025 is identified as a significant and unavoidable impact. Therefore, approval of the project would require a Statement of Overriding Considerations. · Comment 3.5.6: The commenter notes potential confusion regarding mitigation measures and levels of service at the Dublin/Dougherty intersection. The commenter believes that re-striping of the Hopyard overpass would be required to create additional lanes. Response: Mitigation Measure 4.11-1 (b) of the DEIR (page 167) calls for improving Dougherty Road to four lanes in the southbound direction between Dublin Boulevard and 1-580 westbound on-ramp. These lanes will be configured so that the right-most lane would lead exclusively to the 1-580 westbound on-ramp, with the second rightmost lane leading to the overpass or the 1-580 westbound on-ramp. These improvements would result in three southbound lanes leading to the 1-580 overpass. The commenter is correct, in concluding that the re-striping the overpass Transit Center PA 00-013 Page 31 City of Dublin September 2002 would be required to create additional lanes. It is anticipated that an existing southbound shoulder area adjacent to the 1-580 westbound on- ramp would be retried to form the third through lane leading to the overpass. In regard to impacts of the project on the Hopyard/I-580 interchange, Table 23 contained in the DEIR does not identify a significant impact of the project at this intersection. No re-striping would therefore be required. · Comment 3.5.7: The commenter requests a queuing analysis to determine the actual levels of congestion along Hopyard/Dougherty from Owens Drive north of Dublin Blvd. The close proximity of the intersections will have a significant impact on delay and levels of service. Dublin Blvd. should also be studied due to the close proximity of Scarlet Drive to the intersection and the need to run long traffic cycles. Response: The traffic engineering consultant who prepared the traffic study for the DEIR also conducted a supplementary operational LOS analysis at the Dougherty Road/Dublin Boulevard intersection under 2025 plus Project conditions and ultimate geometric improvements. As described in the DELR, the ultimate configuration for the northbound Dougherty Road approach would consist of three left-turn lanes, three through lanes, and two right-turn lanes, for a total of eight lanes. With this lane configuration assumed to be in place for the northbound approach, the operational LOS analysis showed no evidence that traffic on Dougherty Road would back up to Owens Drive in Pleasanton~ On Dublin Boulevard, the distance between Dougherty Road and Scarlet Drive is approximately 1,100 feet, which should provide ample storage for westbound vehicles on Dublin Boulevard approaching Dougherty Road under 2025 plus Project conditions and ultimate geometric improvements. As described in the DEIR, the ultimate configuration for the westbound Dublin Boulevard approach would consist of three left-turn lanes, two through lanes, and one shared through/right-turn lane, for a total of six lanes. Comment 3.5.8: The commenter notes that the eastbound off-ramp at Hacienda Drive and 1-580 would need widening and that overpass at the westbound ramp would need 3 through lanes and a right turn lane. This configuration is different than the proposed overpass configuration at the westbound off-ramp. Response: The Hacienda/I-580 westbound off-ramp intersection would require mitigation measures as listed in the Draft EIR on page 167. These Transit Center PA 00-013 Page 32 City of Dublin September 2002 mitigation measures include the widening of the 1-580 westbound off- ramp to three left-turn lanes and two right-turn lanes, and the widening of the northbound Hacienda Drive overcrossing to three northbound through-lanes and a right-turn "trap" lane onto westbound 1-580. which is consistent with the configuration stated by the commenter for the overpass at the westbound off-ramp. With respect to the eastbound 1-580 off-ramp at Hacienda Drive, this off-ramp was recently widened to two right-turn land and two left turn lanes. No additional improvements would be needed for the eastbound 1-580 off-ramp at Hacienda Drive as a result of the proposed project, since no significant impacts have been identified in the DEIR. · Comment 3.5.9: The design of the street system in Dublin has placed many streets of major proportion quite close together. It is therefore recommended that a traffic simulation model be employed to determine traffic impacts to intersections. Response: It is assumed that this 'comment is made in reference to Dublin Boulevard being close to 1-580, especially as this relates to future traffic conditions at the Dougherty Road/Dublin Boulevard intersection with Transit Center traffic. For the response to this comment, please refer to the response to Comment 3.5.7. It should also be noted that the City of Dublin plans to participate in the development of regional traffic simulation models to coordinate traffic signals across jurisdictional boundaries with the City of Pleasanton. The current 1-580 Smart Corridor Project is expected to facilitate this coordination effort. However, with regard to the Transit Center EIR, CEQA does not require the use of traffic simulation models to analyze potential impacts. The City of Dublin believes the information presented in both the DEIR and FEIR, which employ standard travel demand forecasting models, adequately identifies traffic and circulation impacts and mitigation measures. · Comment 3.5.10: What will the requirement be to improve employee access to public transit opportunities. Response: Regarding accessibility of future project employees to public transit opportunities, future Project employees would have complete access to the East Dublin BART Station where they would have access to Wheels, BART, and bus transfers to ACE stations via walking and/or shuttle buses. In terms of improving access, street circulation in and around the BART Station would become more pedestrian friendly with the narrowing of streets, limited on-street parking, and transit only lanes Transit Center PA 00-013 Page 33 City of Dublin September 2002 (which currently exist for buses accessing the BART Station from Demarks and Iron Horse. In addition, a proposed BART parking structure would help to remove some of the current congestion around the East Dublin BART Station by concentrating the parking in one area rather than spreading out the parking in multiple or temporary surface lots which now exist. The entire circulation system design and concept of the proposed Dublin Transit Center is to concentrate development as close as possible to a central multi-modal public transit station in the Tri-Valley and encourage pedestrian and bike use over single-occupant automobile use. Comment 3.6: City of Livermore · Comment 3.6.1: The DEIR recognizes that traffic conditions on the 1-580 freeway is anticipated to operate at LOS F conditions in the year 2025, and notes that only a partial mitigation measure, payment of fees, is available to assist in reducing this congestion. Response: The DEIR notes that the 1-580 freeway is anticipated to operate at unacceptable levels of service in the year 2025, whether or not the proposed Transit Center is constructed. The DEIR concludes that the project's impact to I- 580 freeway conditions is significant and unavoidable (see Impact 4.11-7). The size and scale of the proposed project is too small to finance mitigation of freeway conditions to a less-than-significant condition; however, the Transit Center will be required to pay traffic impact mitigation fees (see Master Response) which are established in proportion to the project's contribution to regional and local traffic impacts. · Comment 3.6.2: The commenter notes that feasible mitigation measures are available to address regionally significant impacts, including increased financial contributions to construct HOV freeway lanes, financial assistance to construct North Canyons Parkway and others. The DEIR needs to evaluate the appropriate level of contribution to implement these measures. The City of Dublin has approved significant development elsewhere in Dublin and passing the responsibility of cumulative development does not address regional solutions. Response: The City of Dublin is not passing its regional responsibilities to address traffic impacts from private development projects. The development fee programs currently in place in Dublin contribute toward regional transportation improvements and are explained in the Master Response as well as the response to Comment 3.5.1. The proposed Transit Transit Center PA 00-013 Page 34 City of Dublin September 2002 Center development will make a fair share contribution toward implementing these improvements in addition to the mitigation measures required of the project as outlined in the DEIR. The extension of Dublin Boulevard to North Canyons Parkway will be constructed as part of the Eastern Dublin TIF program when the East Dublin Properties project east of Fallon Road is developed in the future. In sum, the City of Dublin believes that planning and implementation of such projects as the Transit Center is one action that local agencies can take to assist in reducing regional transportation congestion. The Transit Center is intended to follow "smart growth" principles promoted by ABAG, the Metropolitan Transportation Commission, the Bay Area Air Quality Management District and other agencies. Under smart growth principles, relatively dense mixed-use development projects are located adjacent to major transportation hubs. Ideally, these projects will reduce vehicle trips on regional routes, such as 1-580, by placing high density residential housing and retail support uses near major job center, all easily accessible by public transit services. · Comment 3.6.3:The City of Liverrnore has adopted a regional component to the City's traffic fee program. Other jurisdictions in the Tri-Valley are encouraged to adopt a similar program. Response: This information is acknowledged. · Comment 3.6.4: The DEIR presents no evidence, other than discussions with DSRSD staff, that adequate potable water supply exists to serve the proposed project. Response: In regard to cumulative water supply for the proposed project, please refer to the letter from Dublin San Ramon Services District (Letter 3.3). Both the text of the DEIR and the DSRSD, the water provider for the City of Dublin as well as other areas, letter indicate that sufficient potable water is available in terms of long-term signed water supply contracts to serve the proposed Transit Center and no additional impacts or mitigation measures are required. The City of Livermore's disagreement with the statement in the DEIR regarding consistency of the proposed Transit Center project with DSRSD's Urban Water Management Plan is noted. However, based on information contained in the DEIR text supplemented by DSRSD's August 16, 2001 letter (Comment letter 3.3) and September 3, 2002 letter (included within this document as Appendix B), the City of Dublin continues to believe that Transit Center PA 00-013 Page 35 City of Dublin September 2002 sufficient water will be available to serve the proposed Transit Center, should the project be approved. · Comment 3.6.5: Recent litigation may affect how, when and how much water can be supplied to the proposed project. Specifically, pursuant to litigation settlement in the Dougherty Valley, a water service analysis was required to be initiated by DSRSD to address provision of water to this project. This water service analysis should have been used for the Transit Center EIR to assess water demand as well as cumulative water demand in the region. Response: Based on a recent letter from DSRSD to the City of Dublin (Letter to Mike Porto, City of Dublin, 9/3/02, attached as Appendix B), DSRSD continues to believe that sufficient water supplies exist to serve this proposed project. This is based on the District's Final Revised Water Service Analysis prepared in December 2001, which included an analysis of all the District's regional service area. · Comment 3.6.6: The commenter disagrees with the findings of the DEIR that information contained in the DEIR ~ulfills Dublin's obligations under Government Code Section 65302.2 dealing with the provision of adequate water supply for general plan amendment. Response: Section 65302.2 of the Government Code requires the City to use DSRSD's Urban Water Management Plan as a source document for the proposed General Plan Amendment. As reflected in the DEIR, the City has considered DSRSD's plan in compliance with the statute A more recent letter from DSRSD staff to the City of Dublin (9/3/02) confirms that DSRSD has adequate long-term water supply contracts with Zone 7 to serve the proposed project. · Comment 3.6.7: The commenter disagrees that the proposed project would have a less-than-significant effect on the City's jobs-housing balance. The commenter believes that project would result in an estimated 2,250 employed residents (based on a maximum of 1500 residences) and 7,832 jobs. Response: Regarding the jobs/housing balance, it is the contention of the City of Dublin that the jobs/housing balance is best viewed on a regional basis and not on a project level, as suggested by the City of Livermore. On a regional level, the project is consistent with "smart growth" policies of Transit Center PA 00-013 Page 36 City of Dublin September 2002 ABAG and other agencies encouraging mixed-use employment, commercial and high density residential projects near major transit hubs. · Comment 3.6.8: Locating the proposed project along a transit line does not fully address the physical impacts of a city-wide jobs-housing imbalance,' specifically traffic impacts. Response: Potential effects of a jobs/housing imbalance may be reflected in environmental conditions such as traffic congestion, noise and air quality impacts of proposed uses. Accordingly, the DEIR addresses potential air quality impacts (Section 4.2), increased storm water impacts (Section 4.7), potential noise impacts (Section 4.9) and traffic and circulation impacts (Section 4.11). · Comment 3.6.9: The DEIR does not include an alternative that'would include a greater number of residential dwellings. Such an alternative may result in lower air emissions and less traffic congestion. Response: In terms of including an alternative that would encompass a greater residential component, such an alternative would not be consistent with project objective 3, increasing employment opportunities through the development of a maximum of 2 million square feet of office, retail and other employment generating land uses. Please note that the EIR Project Description does make a provision that an additional 300 dwellings units could be constructed on Sites D-1 and E-1 within the Transit Center. If this option is exercised, up to 1800 high-density dwellings could be built. · Comment 3.6.10: The Association of Bay Area Governments (ABAG) has assigned a goal of 1,327 affordable housing units to the City of Dublin. The proposed project would comply with the minimum affordable housing requirement contained in the Dublin Zoning Ordinance, which is 5%. The actual proportion of affordable housing should actually be 24%, which is the proportion of ABAG's requirement for moderate and above moderate income housing to low and very low-income household dwelling units. Response: Compliance with affordable housing goals is not a CEQA matter and no further response is necessary; however, whatever method the City of Dublin chooses to meet its housing goals is a land use policy issue and is set forth in the goals, policies and implementation programs of the General Plan Housing Element. Similar to many other cities within ABAG, the City is in the process of updating its Housing Element, The Transit Center PA 00-013 Page 37 City of Dublin September 2002 Transit Center will be required to comply with all applicable housing policies and implementing programs. However, since publication of the DEIR, the project applicant has revised the project description (January 2002) to include up to 15% of planned residences to be affordable to the project to moderate, low and very low income households. The project description also notes that the applicant would be requesting assistance &om the City of Dublin and other sources, such as reductions in development costs and other incentives to make this a reality. · Comment 3.6.11: The DEIR should be revise and re-circulated to provide an adequate, thorough analysis of regional issues. Response: The Draft and Final Ears have analyzed potentially significant environmental impacts as related to the proposed Transit Center project, as required by CEQA. Both the Draft and Final documents provide information at a programmatic level regarding the environmental consequences of potential development of the proposed project. This environmental information together with the General Plan and other land use policy analysis, will be reviewed by Dublin decision makers as they consider action on the project. Comment 3.7: Alameda County Zone 7 · Comment 3.7.1: The DEIR does not address the potential of salt imbalance to the ACWD due to irrigation with recycled water. This impact is being addressed in a joint ACWD-DERWA study. Response: Comment noted that Zone 7 considers salt loading to the main groundwater basin due to irrigated landscaping with recycled water to have minimal to no impact. The impact of the proposed project on potential salt loading to Alameda County Water District (ACWD) water supplies downstream on Alameda Creek are also considered to be insignificant. As discussed on page 181 of the DEIR, only 15% of the net project area, or about 13 acres, could potentially be landscaped and therefore irrigated with recycled water. This represents a small percentage of the area that would be ultimately be irrigated with recycled water in Eastern Dublin, and an even smaller fraction of the area irrigated with recycled water within the entire Alameda Creek watershed. Salt-loading is a regional issue that is being addressed by both DERWA (for recycled water in Dublin and San Ramon) and by Zone 7 (for South Bay Aqueduct water imported for irrigation in Livermore, Pleasanton and Dublin). DERWA is Transit Center PA 00-013 Page 38 City of Dublin September 2002 working in cooperation with ACWD to mitigate projected salt loads impacts on ACWD treatment facilities in Fremont. · Comment 3.7.2: The DEIR notes that the proposed project would generate additional acreages of impervious surfaces, impacting downstream stormwater facilities and will be subject to drainage fees. Response: The comment regarding mitigation for identified stormwater runoff impacts through payment of Zone 7 fees is acknowledged and no further mitigation is needed. · Comment 3.7.3: An analysis for drainage lines G-1 and G-2 should be done, similar to the analysis done for Line G-5 in the DEIR. Response: Zone 7 recently completed a special Drainage Area 7 7-1 program update of channel improvements costs by Schaaf & Wheeler, Consulting Civil Engineers (dated 6/30/00). The report addresses increases in peak flows of all storm drain channels in the Zone 7 service area due to anticipated development of the Dublin Transit Center and other nearby development projects. The report includes peak stormwater flows, cost estimates of needed improvements within all channels and fees that would need to be collected in order to accommodate future peak storm flows. Since new drainage fees are anticipated to be adopted by the City of Dublin prior to any development within the proposed Transit Center and fees levied on new development within the Transit Center as a standard condition of approval, with a portion of these fees forwarded to Zone 7, any increases in stormwater flows attributed to the Transit Center will be off-set future regional drainage improvements financed by increased Zone 7 drainage fees. One of the goals described in the Eastern Dublin Specific Plan is that as development occurs, required drainage channel improvements will be constructed to adequately accommodate increased drainage flows. With the development of the neighboring Santa Rita area by the Alameda County Surplus Property Authority, the Authority commissioned a master drainage study entitled "Santa Rita Drainage Master Plan" that includes the drainage area of the proposed Transit Center. This master plan was prepared by Brian, Kangas, Foulk in May, 1999. Zone 7 and the Alameda County Flood Control District has reviewed and approved this drainage analysis of the project area. This document describes the existing and proposed drainage flows and needed drainage improvements surrounding the Transit Center that have been installed to control drainage based on future development projects in accordance with Zone 7 Transit Center PA 00-013 Page 39 City of Dublin September 2002 flood control criteria. The master plan identifies a new drainage system that will be needed to convey upstream flows from the existing flow splitter above Broder Road across existing Zone 7 G-l, G-2 and G-5 drainage channels through Caltrans culverts under the 1-580 freeway to the G-1 drainage channel in Pleasanton. One of the issues identified in the study is the G-1 100-year flow is 1,130 cubic feet per second (cfs), but the design capacity of the 1-580 culvert is 800 cfs. The study recommends the existing splitter be removed, a new storm drain splitter be installed, widening the G-5 storm drain channel and new storm drain lines through the existing BART parking lot along Arnold Road to redistribute drainage flows from the G-1 channel to other existing culverts crossing the 580 freeway. An updated HEC-1 drainage analysis was completed by Frank Codd (December, 2000) that documents that the flows of the fully developed Transit Center and surrounding properties to the existing Caltrans box culverts crossing 1-580. The analysis concludes that the increased stormwater flows due to the development of the proposed Transit Center were less than identified in the original analysis contained in an earlier drainage study completed in 1994. Since many of the recommended drainage improvements that were part of Alameda County's Santa Rita development have now been constructed, the only remaining phase to be constructed is the removal of an upstream flow splitter that will reduce the stormwater flows from the G-1 line to the G-2 and G-5 lines. Plans for the removal of the flow splitter have been submitted to the City of Dublin for review. Therefore, development of the Transit Center would not significantly increase storm flows into the G-2 Line. · Comment 3.7.4: The 24-inch Santa Rita-Dougherty pipeline should be shown along the former Southern Pacific Railroad right-of-way. Response: The 24-inch Santa Rita-Dougherty pipeline, it is hereby corrected by reference on Exhibits 11 and 19 to be located along the former Southern Pacific Railroad right-of-way. · Comment 3.7.5: Access should be provided to several Zone 7 pipeline facilities located near the proposed project. Encroachment permits will be required prior to construction within a Zone 7 easement area. Future construction plans should be reviewed by Zone 7. Response: Zone 7's request for limitations on landscaping near Zone 7 facilities and the need for future encroachment permits is acknowledged and will be incorporated in development standards as part of Stage 2 PD Transit Center PA 00-013 Page 40 City of Dublin September 2002 rezonings. Referral of future construction plans to Zone 7 will be made by the City of Dublin at the time specific development is proposed. · Comment 3.7.6: Zone 7 does not have transmission lines adjacent to or within the project area. Response: The comment by Zone 7 that no transmission facilities exist within the project area is acknowledged. No further action is required. · Comment 3.7.7: There are several numbers regarding water supply that need to be updated as identified in the Zone 7 comment letter. Response: Updated informati°n provided by Zone 7 concerning sustainable water supply is hereby incorporated by reference in the EIR. This information concerns Zone 7's sustainable water supply from the State Water Project and the sustainable average yield in Lake Del Valle. These are also referenced in the Modifications to the EIR section. · Comment 3.7.8: The DEIR should clearly identify both treated and recycled water demands for the project in the same five-year format as Table 26. This information will be used by Zone 7 for water supply planning purposes. Response: Zone 7's request for use of potable and recycled water demand in five-year increments cannot be provided at this time, since construction of specific development projects within the Transit Center is not known. Reference the Phasing section of the Project Description on p.14 of the DEIR. Information on estimated water demand is included in the DEIR at full buildout of the proposed project, since this information has been provided by the project applicant. · Comment 3.7.9: Zone 7 estimates an annual recycled water volume of 41 acre-feet, which translates to 36,000 gallons per day, not 27,500 gallons per day as identified in the DEIR. Response: In preparing this response, the City reanalyzed estimates of recycled water needs as presented in the DEIR. The estimate has been revised so that the use of recycled water at full project buildout would be 29,456 gallons per day. This includes an estimated 1.0 acres of landscaped median not included in the original estimate included in the DEIR. This Transit Center PA 00-013 Page 41 City of Dublin September 2002 calculation assumes 67 net acres of development on the site (minus roadways) with. 15 % of the site devoted to landscaping. Comment 3.8: Bay Area Rapid Transit District (BART) · Comment 3.8.1: BART supports the proposed Transit Center and has been working with the Alameda County Surplus Property Authority to make the plan a reality. The basic concept of the project, to replace existing surface parking lots with a parking garage, will facilitate a transit-oriented development. This proposal will also enhance access to and use of the BART station and will be an enhancement to the surrounding area. ResPonse: In regard to the comment that the Bay Area Rapid Transit District (BART) supports the proposed Transit Center project, this comment is acknowledged and no further analysis is necessary. · Comment 3.8.2: Construction of the proposed 1,700-space parking garage would replace existing temporary and surface parking spaces, but would not increase suppl3/. Response: The comment notes that there would be no increase in parking supply. In October of 1999, ACSPA submitted a request to the City of Dublin to add additional temporary parking stags to reduce a serious parking problem at the Dublin/Pleasanton BART Station. At the time the additional temporary stalls were constructed, approximately 1138 residential units were occupied in Eastern Dublin creating a higher demand for parking at the Dublin/Pleasanton BART Station. A temporary lot for apProximately 421 tong term parking stalls was created. The project proposes to incorporate the temporary 421 stalls with the permanent 1250+ stalls for a combined total of approximately 1700 permanent stalls. Therefore, additional permanent parking would be secured. This comment is acknowledged and no further analysis is needed. · Comment 3.8.3: BART requests that the possibility of adding approximately 500 additional Parking spaces should be analyzed as part of the proposed Transit Center project. Response: The following additional analysis has been prepared in response to the BART request. Project Description The DEIR assumed 1,700 spaces parking spaces for the proposed 5-story BART parking garage. Based on the BART comment letter (Letter 3.8), BART has an existing agreement with the applicant (Alameda County Surplus Property Authority) to provide for an additional 250 spaces, however, BART now seeks to add approximately 500 additional parking spaces on additional floor(s) of the proposed parking garage. With these Transit Center PA 00-013. Page 42 City of Dublin September 2002 additional spaces, there would be a total of 2,200 parking spaces with the expanded garage, a net difference of 500 parking spaces. Trip Generation After publication of the DEIR, both Alameda County and BART staff have indicated that number of existing parking spaces at the East Dublin BART Station was 1,870 spaces rather than 1,680. This was due to available street parking on DeMarcus and Iron Horse Boulevard as well as several existing smaller surface parking lots not accounted for in BART's total for the East Dublin BART surface parking spaces. For these reasons, the AM and PM peak hour trip generation rates would be reduced slightly from those used in the Dublin Transit Center DEIR (daily rates would remain unchanged). Daily and peak hour trip generation for an additional 520 parking spaces has been shown in Table A, below. As calculated, an enlargement of the proposed garage by 500 spaces would result in an additional 1,804 daily trips with 152 AM peak hour trips and 134 PM peak hour trips. Table A Dublin Transit Center Proposed East Dublin BART Parking Garage Expansion AM and PM Peak Hour Trip Generation a. Dublin Transit Center DEIR (1,680 spaces):1 Daily: 1,680 spaces x 3.47 trips/space = 5,830 trips AM: 1,680 spaces x 0.54 trips/space = 904 (788 in, 116 out) PM: 1,680 spaces x 0.43 trips/space = 274 (222 in, 502 out) b. East Dublin BART Parking Garage Expansion (2,200 spaces): Daily: 2,200 spaces x 3.47 trips/space = 7,634 trips AM: 2,200 spaces x 0.48 trips/space =1,056 (920 in, 136 out) PM: 2,200 spaces x 0.39 trips/space =858 (263 in, 595 out) c. Net Trip Increase: Daily: 7,634- 5,830 = 1,804 trips AM: 1,056 - 904. = 152 (132 in, 20 out) PM: 858 - 724 = 134 (41 in, 93 out) Trip Distribution Peak hour vehicle distribution for the additional BART parking garage trips was based on the same distribution found in the Dublin Transit Center DEIR and was estimated as follows: Transit Center PA 00-013 Page 43 City of Dublin September 2002 Hacienda Drive to/from the south 55% Hacienda Drive to/from the north 3% Dublin Boulevard to/frOm the east 10% Dublin Boulevard to/from the west 30% Arnold Drive to/from the north 2% Total 100% AM and PM peak hour trips attributed to the proposed East Dublin BART Station parking garage expansion were distributed onto the street network and added to "key" intersections within the project area. Anticipated Traffic and Circulation Impacts Additional peak hour vehicle trips related to the parking garage expansion were added to key intersections in the project area. 'Key intersections were identified as any intersection that is currently operating between LOS D (0.86) to LOS D (0.90) during the AM or PM peak hour with proposed Dublin Transit Center traffic. The addition of BART parking garage expansion trips that would cause these key intersections to operate at LOS E (0.91) would be considered a significant impact and require additional mitigation measures beyond those recommended in the DEIR. Under Existing + Future Base + Proposed Project conditions, five key intersections were identified as operating at LOS D (0.86-0.90) and are shown in Table B. As calculated, the addition of proposed East Dublin BART Station parking garage expansion trips to existing plus future base plus project conditions would not cause key intersections in the study area to operate below level of service D (0.90). However, there would be slight increases in signalized intersections' volume/capacity ratio (= or < 0.01) during the AM or PM peak hour. Under Cumulative Year 2025 + Proposed Project, six key intersections were identified as operating at LOS D (0.86-0.90) (see DEER Table 23) and are shown in Table B. The addition of 500 spaces to the proposed BART parking garage trips to Cumulative Year 2025 plus project conditions would not cause key intersections in the project area to operate below level of service D (0.90). There would be slight increases in signalized intersections' volume/capacity ratio (= or < 0.01) during the AM or PM peak hour.

Santa Rita/I-580 EB -- D 0.88 -- D 0.88 Of&amp/Pimlico Conclusion In summary, the addition of 500 parking spaces for the proposed East Dublin BART parking structure beyond the 1,680 parking spaces analyzed in the DEIR would not cause significant transportation impacts beyond that previously analyzed in the DEIR. This would be true for existing plus future base plus project and Cumulative Year 2025 plus project conditions. Significant and unavoidable impacts would still result regarding cumulative traffic impacts (Impact 4.11-5) and mainline freeway operations (Impact 4.11-7). Given that the 1-580 presently operates at congested levels of service without the addition of project traffic, the addition of 500 more parking spaces at the BART station is not anticipated to divert a significant enough number of vehicles from the freeway to reduce impacts to the 1-580 freeway. · 'Comment 3.8.4: The commenter notes that the Final Supplemental EIR for the West Dublin/Pleasanton BART Station and Transit Village stated that BART is considering a parking reservation program at both the East Transit Center PA 00-013 Page 45 City of Dublin September 2002 and West Dublin stations. This program should be incorporated by reference into the Transit Center EIR. Response: This information on BART parking programs is acknowledged and hereby incorporated by. reference into the EIR. · Comment 3.8.5: The BART Board of Directors has adopted a new parking limit policy reducing a single parking event from 72 to 24 hours. Implementation of this policy could result in spillover of parking onto nearby streets. Response: The DEIR identified future potential parking impacts from the BART station on nearby streets and other areas (Impact 4.11-4, parking impacts). Mitigation Measure 4.11-2 requires the City of Dublin to limit on-street parki.ng near the BART station. Further, through the Site Development Review process and other future levels of entitlements, to ensure that private parking lots and structures discourage unauthorized BART parking. No further analysis is therefore necessary.' · Comment 3.8.6: Implementation of the proposed project may require the removal of a bus loading area that serves Stockton Metro Area Regional Transit, Amtrak Thruway bus, Modesto Transit and CCCTA Route 259. BART suggests that a relocation plan for transit service providers be prepared between the City of Dublin Alameda County Surplus Property Authority and BART. Response: This comment is acknowledged and will be addressed as part of Stage 2 Planned Development rezoning applications for individual development sites within the Transit Center adjacent to the BART station. Comment 3.9: San Joaquin County Community Development Department (Note: This comment letter was received after the close of the EIR comment period but is being responded to since a copy of the DEIR was delivered late to San Joaquin County.) · Comment 3.9.1: The commenter notes the DEIR does not address cumulative traffic on 1-580 east of Fallon Road. This includes potential impacts to the 1-580 east of Fallon Road and includes Grant Line Road, Altamont Pass Road and Byron-Bethany Road. These roads are currently Transit Center PA 00-013 Page 46 City of Dublin September 2002 heavily congested and payment of regional impact fees do not include these roadways. Response: DEIR Impact 4.11-7 notes that traffic congestion on the 1-580 freeway will be significant and unavoidable in Year 2025 with or without the proposed Transit Center. The methodology used to determine this impact was the Tri-Valley Transportation Model, which has been used at the request of Caltrans. The model chosen to address impacts is limited to roadways within the eastern Alameda and southern Contra Costa County areas, consistent with normal and customary traffic impact analyses. The model does not include roadways outside these areas. The intent of the proposed project is to reduce auto traffic on the 1-580 and other roads by providing a mix of housing (up to 1500 dwellings) in addition to office and retail uses within close proximity to a major regional transportation hub. As noted in the Master Response, the proposed project would contribute to regional transportation improvements, most notably the 1-580 freeway, which is the primary automobile route between Dublin and San Joaquin County. · Comment 3.9.2: The commenter notes that Alameda County has requested San Joaquin County to address cumulative traffic impacts along the 1-580 and 1-205 freeway. The office component included in the proposed Transit Center will contribute to an imbalance of job and housing development in Alameda County and will continue to create more need for residential development in San Joaquin County. Response: The City of Dublin is unaware of requests by Alameda County with respect to San Joaquin County development projects. The City acknowledges, however, that an imbalance in residential and job growth can result in congested roadways. Located at the intersection of two major regional corridors and anchored by a BART station, the project is proposed in response to such pressures. This is further reflected in the Project Objectives (DEIR pp. 26-27), which include creating a state-of-the-art mixed use center near major transportation hubs whereby office employees have the opportunity to either live within the project area or may either take BART or another public transit carrier to their respective place of employment. This planning approach is intended to respond to planning mandates for higher intensity development near public transit hubs, as expressed by ABAG, the Metropolitan Transportation Commission, Bay Area Air Quality Management District and others, and is intended to assist in providing a solution to a regional jobs-housing imbalance. Transit Center PA 00-013 Page 47 City of Dublin September 2002 · Comment 3.9.3: The commenter requests that the EIR address cumulative impacts to the 1-580 freeway from Fallon Road east to 1-205 and county access roads to 1-580 in the vicinity of the Altamont Pass and Byron- Bethany Road. Response: According to the traffic study prepared for the DEIR, most project trips are expected to originate either from the south or from the west in relationship to the project location. The Tri-Valley Transportation Model used in the traffic study to forecast Year 2025 cumulative traffic conditions is focused on the Tri-Valley area and does not include a detailed roadway network for San Joaquin County. Project trips to/from the more distant east (i.e., San Joaquin County) are expected to be limited and should dissipate further away from the project towards San Joaquin County. As a result, the Transit Center project is not expected to have any significant traffic impacts on roadways near or inside San Joaquin County. · Comment 3.9.4: The jobs-housing balance section of the DEIR should identify where employees of the office buildings are likely to live, given their household income and the local and regional supply of available housing as the project is occupied. Response: Specific information regarding the residence of future project employees has not been provided by the project sponsor. However, the purpose of the traffic model used to assess project impacts (the Tri-Valley Transportation Model) has made assumptions regarding future employment and location of housing. Therefore, transportation-related impacts of the regional jobs-housing balance have been accounted for the traffic and transportation analysis of the proposed project. Comment 4.1: Rails to Trails Conservancy · Comment 4.1.1: Special emphasis should be placed on providing bicycle and pedestrian connections between the Iron Horse Trail and the proposed Transit Center. Response: Appropriate standards regarding bicycle and pedestrian connections between the proposed project and the Iron Horse Trail should be addressed as part of the Stage 1 and Stage 2 Planned Development rezoning applications. Maximizing non-auto transit modes is a basic objective of the Transit Center project. Transit Center PA 00-013 Page 48 City of Dublin September 2002 · Comment 4.1.2: The commenter does not believe that the 10-foot trail width proposed for the Iron Horse Trail is sufficient to accommodate estimated activity for the facility. Response: The'Iron Horse Trail is a facility that has been planned by the East Bay Regional Park District, not the City of Dublin. Trail improvements should be reviewed with the Park District. · Comment 4.1.3: The commenter asserts that, contrary to the DEIR, families would desire to live within the residential portion of the project. Response: The residential component of the proposed project are planned as high density dwellings in 4 to 5 story configurations. Dwellings may contain small patios and balconies, . however, the project would not include larger outdoor recreational areas. The DEIR reasonably assumes that families generally may be less attracted to such unit types. Neither the project applicant nor the City discourages families from locating in this project · Comment 4.1.4: The commenter asserts that, contrary to the DEIR, that additional enhancements be included as part of the project, including a "bikestation." Response: The comment regarding provision of a "bikestation" within the Transit Center will be discussed as part of the Stage 2 Planned Development application which deals with the design of the proposed project.

Letter R-2.1: Alameda County Congestion Management Agency · Comment R-2.1.1: The second paragraph under the "New Impact" section, the reference to "the ACCMA standard of LOS E would not be met" should be deleted, since this standard applies to the LOS Monitoring Program which monitors existing conditions and does not apply to the Land Use Analysis program, which monitors the regional transportation network for study years 2005 and 2025. Response: Comment acknowledged. The discussion o£ LOS E was included in the New Impact section of the Re-circulated Impact to describe that the proposed Transit Center project would result in a significant and unavoidable impact to the 1-680 freeway. The statement is based on the DEIR Transportation and Circulation section Standards of Significance (page 145). Refer to the Response to DEIR comment 3.2.3, whereby it is acknowledged that the ACCMA does not have a policy for determining threshold of significance, although LOS E is still used in the EIR as a threshold Of significance based on professional judgment.

TO: Affected Agencies and Organizations - FROM: City of DUblin community Development Department RE: Re-circulation of a portion of Draft Environmental Impact Report for the proposed Dublin Transit Center (PA 00-013), SCH # 2001120395 Background: ,The proposed Transit Center includes the phased construction of up to · 2.0 million square feet of office space, up to 70, 000 square feet of local-serving retail commercial uses, up to 1500 attached dwelling units, and a multi-story parking garage for BART parking at the existing Eastern DUblin BART station on a 91-acre project area. The Transit Center 'site is located between DUblin Boulevard and the 1-580 Freeway, and between the Iron Horse Trail and Arnold Drive in the Eastern Dublin portion of the City of Dublin, AlamEda County. The project would also include construction of new streets, landscaping and utility connections to serve the proposed development. The property owrter, the Alameda County Surplus Property Authority, has requested · approval cfa General Plan Amendment, an amendment to the Eastern Dublin Specific Plan, a Stage 1 PD-Plarmed Development rezoning, a development agreement and a parcel map to implement the above-described development program~ Environmental Review. A Draft EIR (DE]R) for the Transit Center project was prepared by the City of DubLin and drculated for public comment for 45 days between July 6 and AuguSt 21, 2001, pursuant to the California Environmental Quality ACt (CEQA) and its related Guidelines. The City prepared draft responses to the comments received during the public review period. The :responses will be compiled irt a Final E]R. Re-circulation of Portion o£ DEIR re: Impacts to I'680: In the course of preparing a response to comments regarding the potential for project impacts on 1-680, the City developed irrformation revealing a new sigrdficant impact that was not identified .in the original DE]R.

New information generated for 1-680 operations shows that the project may also have significant mainline freeway impacts for 1-680 in the year 2025. Therefore, pursuant to CEQA Guidelines Section 15088.5, information and analysis regarding this new significant impact is being circulated for a 45-day public review and comment period. The new impact is described in more detail below. New Impact: The 1-580/I-680 freeway interchange is located more than one mile to the west of the project area. However, mainline volumes along 1-680 both north and south of 1-580 have been evaluated for peak hour operation. These volumes and resulting impacts are shown on the following Table 25a below. As shown on Table 25a, with the Project traffic added to Year 2025 No Project mainline freeway volumes, projected LOS for both directions of travel on 1-680 would remain unchanged during the AM and PM peak hours. With a projected LOS F in the PM peak hour northbound direction between 1-580 and Alcosta Boulevard, the proposed Project trips would be adding to an already deficient condition, and the ACCMA standard of LOS E would not be met, even without the Project trips. Although future developments in the proposed Project would contribute TVTD regional traffic improvement fees, which would also assist in funding the planned 1-680 auxiliary lanes between Bollinger Canyon Road and Diablo Road, based on the TVTC Strategic Expenditure Plan, these measures will not avoid or substantially reduce the impact to the 1-680 freeway. Therefore, the project impact on 1-680 would be significant and unavoidable. Table 25a.

(2) Year 2025 base year no project volumes based on the Updated Tri-Valley Transportation Model using ABAG projections '98. Proposed Dublin Transit Center peak hour trips were then manually added into these base volumes to generate Year 2025 with project volumes. The following new impact is hereby identified and discussed as Impact 4.11-8 and is included by reference in the Dublin Transit Center DEIR. Impact 4.11-8 (mainline freeway operations, 1-680): In 2025, without the proposed Transit Center project, 1-680 mainline conditions would exceed Alameda County Congestion Management Agency's threshold of significance. The addition of Transit Center traffic would worsen that condition for the 1-680 freeway near the project area (significant and unavoidable impact, mitigation is not feasible since freeway improvements are not under the jurisdiction of the City of Dublin). Close of Re-circulation Comment Period: Pursuant to Guidelines Section 15088.5 (f) (2), the City of Dublin requests that any comment on the new impact be limited to the new impact being disclosed in this Re-circulated DEIR. The close of comment period for the re-circulated DEIR information is 5:00 p.m., August 30, 2002.

The project is currently undergoing environmental review and the City is preparing responses to comments on the Drift Environmental Impact Report (PA00-13). As noted in our August 16, 2001 letter, the Dublin San Ramon Services District (DSRSD), the water supplier for the area in which the proposed Dublin Transit Center is located, identified no impacts or necessary mitigations beyond those identified in the Drift EIR. Further, our March 26, 2002 letter to Mr. Michael Porto, explained the various sources of water supply available to DSRSD through Zone 7 and concluded "DSRSD does have adequate long term water supply contracts with Zone 7 [Water Agency] to serve this project." In the DSRSD Urban Water Management Plan (UWMP) tM demand for the Transit Center was assumed to be 185,000 gallons per day (gpd). As now proposed, the demand will be 447,000 gpd. This is an increase in demand of 262,000 gpd. DSRSD is able to satisfy this increased demand because a number of other projects already constructed within the City of Dublin have an actual demand which is lower than that included in the UWPM. DSRSD is currently preparing a comprehensive update of its UWMP to reflect these lower demand projects. This revision will further confirm that an adequate water supply is available. Until that time, an examination of the magnitude of the increased demand for the Dublin Transit Center may also be useful in illustrating that DSRSD has the needed supply. DSRSD's Final Revised Water Service Anaiysis (December 2001) analyzes in detail DSRSD's water demand and supply projected for 2020. Table 2-1 in the analysis identifies DSRSD as the water supplier for Dublin and Dougherty Valley, projecting build-out demands of 12,660 acre feet per annum (afa) and 4,560 ara, respectively. Thus, the total water demand projected for build-out of the DSRSD service area is 17,220 afa. The project's 262,000 gpd increased demand over plmmed demand converts to 293.5 afa. This is an increase of just 1.7% from the long-term demand projections. As noted above, DSRSD expects to meet this demand under its current contracts, and no additional mitigation is necessary for this project in the long or short term. The D~blin San Ramon Services District is a l~lblic Entity Mr. Eddie Peabody City of Dublin September 3, 2002 Page 2 of 2 If you need any further information, please do not hesitate to contact me.

These trip rates were taken from the April 2002 San Diego Traffic Generators Manu_a!, which are more conservative (i.e., higher) than the ITE trip rates for this type of land use. It is my understanding that an 8.7-acre neighborhood park has been proposed within the Transit Center area that could' be large enough, to include sports facilities. Based on the above trip rates, the proposed park would generate traffic volumes that are considerably low, including approximately 38 AM peak hour trips and 26 PM peak hour trips. As a result of these low traffic volumes, the proposed park within the Transit Center area is expected to have no significant traffic impacts on the adjacent street system. cc: Lee Thompson Mike Porto GADEFELOPiIgublin Transit Ctr~park trip gen m~rno.doc
