4.1 Cumulative Impacts

Transcription

1 Chapter This chapter identifies cumulative impacts, significant and unavoidable impacts, significant irreversible environmental changes, and growth-inducing impacts Cumulative Impacts CEQA defines cumulative impacts as two or more individual effects which, when considered together, are considerable, and suggests that cumulative impacts may result from individually minor but collectively significant projects taking place over a period of time (State CEQA Guidelines Section ). CEQA documents are required to include a discussion of potential cumulative effects when those effects would be significant, and the State CEQA Guidelines suggest two possible methods for assessing potential cumulative effects: ) the list approach and ) the projection approach (State CEQA Guidelines Section 0). The focus of analysis is to identify the Proposed Project s contribution to cumulative impacts that are significant and to assess whether the Proposed Project s contribution would be considerable. Where the Proposed Project would have no impact on a resource or can be clearly shown to have a lessthan-considerable contribution to potential cumulative impacts, the discussion of cumulative impacts is brief. Where cumulative impacts can be shown to be less than significant in the area where the Proposed Project would contribute, the discussion is also brief. Where the Proposed Project has a potential to contribute considerably to a significant cumulative impact, the analysis is more detailed but remains focused on the Proposed Project s potential contribution rather than articulating the cumulative impact comprehensively. Under CEQA, the Peninsula Corridor Joint Powers Board (JPB) is not responsible to mitigate the overall cumulative impact. Specifically, the High-Speed Rail (HSR) Blended Service (described fully in Section..., Rail Projects Planned within the Caltrain Corridor) is not the Proposed Project being analyzed in this EIR or that is being considered by the JPB for potential approval. The JPB is responsible for analyzing potentially feasible mitigation to address the Proposed Project s considerable contributions to identified significant cumulative impacts only. Thus, the obligation to assess mitigation is limited to the fair share portion of a significant cumulative impact that is due to the Proposed Project s considerable contribution. Other cumulative projects have a similar obligation for their contributions to significant cumulative impacts. Thus, for example, in any future environmental evaluation of Blended Service, the California High-Speed Rail Authority (CHSRA) would be responsible for assessing feasible mitigation for its direct project impacts as well as any considerable contributions to significant cumulative impacts... Approach and Methodology CEQA Guidelines Section 0(b) states that the discussion of cumulative impacts should include: Either ) a list of past, present, and probable future projects producing related or cumulative impacts or ) a summary of projections contained in an adopted general plan or similar - IC 000.

2 0 0 0 document, or in an adopted or certified environmental document, that described or evaluated conditions contributing to a cumulative impact. A discussion of the geographic scope of the area affected by the cumulative impact. A summary of expected environmental effects to be produced by these projects. Reasonable, feasible options for mitigating or avoiding the project s contribution to any significant cumulative effects. This EIR used a hybrid approach, explained below, to best disclose different cumulative impacts. Projections: This approach is used to disclose broad regional cumulative impacts related to regional air quality, greenhouse gas emissions, public services and utilities, and transportation/traffic (for general growth driving traffic and transit use). List Approach: Specific projects in or adjacent to the Caltrain corridor from San rancisco to San Jose were examined for the potential, along with the Proposed Project, to result in cumulatively significant localized impacts. This analysis considered transportation projects proposed for the Caltrain Corridor, as well as land development projects that are planned directly adjacent to the Caltrain Corridor. The list approach was used for analyzing impacts related to aesthetics, local air quality, biological resources, cultural resources, electromagnetic fields and electromagnetic interference (EM/EMI), geology, soils and seismicity, hazards and hazardous materials, hydrology and water quality, land use and recreation, noise and vibration, and transportation/traffic (for analysis of construction transportation and traffic effects and for transportation improvements assumed for cumulative ridership and traffic analysis). Table - summarizes the methodology used for each cumulative subject analysis as well as the geographic area of analysis. As described in Section.0, Approach to Impact Analysis, the Proposed Project would have no impact on mineral resources or agricultural resources. Because the Proposed Project would have no impact, it cannot contribute to any potential cumulative impacts and these resource areas are not discussed further in the cumulative impact analysis... Projections/Regional Growth Characteristics The Association of Bay Area Governments (ABAG) projections of land use and population growth were used to estimate overall growth in San rancisco, San Mateo and Santa Clara Counties. These projections are shown in Table -. The Santa Clara Valley Transportation Authority (VTA) travel demand forecasting model (VTA Model ) VTA was used to develop the travel forecasts for development and growth through the year 00 in the corridor. The ridership estimates and the ABAG projections of land use and growth were also used to model traffic conditions along the corridor. VTA s transportation model is an analytical tool that predicts travel patterns based upon spatial relationship between socio-economic characteristics of population and employment locations, tripmaking and economic-related activities in those areas and interconnecting transportation facilitates, including roadway, transit and bicycle and pedestrian modes of travel. The VTA Local Transportation Model Consistency Guidelines (00) outlines how the model may be used by local jurisdictions to develop the local transportation models. As noted in Section., ridership is reported using boardings in this EIR, not boardings plus alightings. - IC 000.

As explained in Appendix I, the socioeconomic data used for the ridership model was based on available ABAG SCS forecasts in late 0 when project EIR analysis began. The ABAG 0 projections released in fall 0 are slightly different, but the differences are not large enough to have a significant influence on the ridership forecasts or on the EIR traffic analysis. Source: U.S. Census 00; Appendix I, Ridership Technical Memorandum... Projects Considered Reasonably foreseeable future projects are defined as the projects that have been adopted or have otherwise demonstrated likelihood to occur based on documentation from project sponsors. There are three types of cumulative projects considered: rail projects planned within the Caltrain Corridor, other regional transportation improvements, and land development adjacent to the Caltrain ROW. or land development along the Caltrain ROW, the JPB requested lists of reasonably foreseeable projects from cities along the Caltrain and additional projects were added based on general knowledge. The geographic areas considered for cumulative impact analyses vary by individual resource, and can include different scales of impact (such as for criteria pollutants or greenhouse gases). The geographic area is noted in the beginning of each subject analysis. Table - presents the applicable planning jurisdictions, the potential cumulative impact areas, the estimated construction schedule associated with each cumulative project, and the distance of the cumulative project to the Caltrain ROW. The project numbers in Table - correspond to the project numbers in igure -. igure - shows the approximate location of each project with respect to the Caltrain ROW and proposed project components. The column titled Potential Cumulative Impact Areas generally summarizes the anticipated cumulative impact areas known at this time. Project information listed in Table - is based on information supplied by the cities the surrounding Caltrain ROW and available environmental documents and information posted on agency websites.

18 Rail Projects Planned within the Caltrain Corridor High-Speed Rail Blended Service from San Jose to San rancisco Blended service will include a number of different actions by different parties. The CHSRA is responsible for high-speed rail service planning. The TJPA is responsible for the Transbay Transit Center and Downtown Extension which would serve both Caltrain and HSR, in addition to other transit providers at the TTC. The JPB is responsible for Caltrain electrification to ourth and King and ultimately for Caltrain service to TTC once DTX and TTC are completed. Both HSR blended service and the TTC/DTX project are discussed together below for the ease of reader review of blended service improvements overall. This project HSR Blended Service is Project #a on Table - and in igure -. The CHSRA previously prepared a final program-level environmental analysis of a statewide HSR system (CHSRA 00). The program-level analysis included an evaluation of various alignments for high-speed service. In 00, the CHSRA issued a final program-level environmental analysis of the Bay Area to Central Valley alignments. This analysis identified the Pacheco Pass and the Caltrain alignment as its preferred alternative. There were several legal challenges to the final program-level environmental analysis of the environmental analysis for the Bay Area to Central Valley alignments that resulted in court orders to make certain revisions to the inal Program EIR. Revisions to the inal Program EIR were completed in 00 and 0. Subsequent to certification of the 0 revisions, the CHSRA confirmed that the selected route for the California HSR system is the Pacheco Pass alignment from the Central Valley to the Bay Area and the Caltrain corridor for the Bay Area segment from San Jose to San rancisco. In 00, CHSRA began project-level analysis of a grade-separated, four-track system from San Jose to San rancisco, including an alternatives analysis and a supplemental alternatives analysis. The four-track proposals by CHSRA were controversial along the Peninsula corridor, with a diversity of opinions about the project. Taking into account these concerns, CHSRA decided in 0 to change its approach for the Peninsula corridor and embrace a Blended Service concept in which Caltrain and CHSRA would share operations on the corridor and CHSRA would primarily be located within the Caltrain right of way (CHSRA 0a). Blended Service would consist of electrified Caltrain trains and HSR trains mostly using the same tracks from San rancisco to San Jose, with a section of passing tracks for scenarios with up to four HSR trains per peak hour per direction (pphpd). There would be no Blended Service south of Santa Clara. Caltrain and CHSRA have engaged in planning level studies of Blended Service to demonstrate its viability. The details of Blended Service are not available at this time. Additional planning and design will be done later and evaluated in a separate environmental evaluation of Blended Service by the CHSRA. or purposes of this cumulative analysis, two representative Blended Service scenarios are considered: the - scenario and the - scenario: The Peninsula Corridor Electrification Project would replace approximately percent of the revenue service fleet with EMUs for service from San rancisco to San Jose. Additional funding would need to be secured beyond that available for the Proposed Project to provide sufficient rolling stock to have 00 percent electrified service from San rancisco to San Jose. Diesel service would continue from Gilroy to San Jose under all scenarios. - IC 000.

19 0 0 0 Under the - scenario, up to two HSR trains pphpd in addition to the six Caltrain trains pphpd planned under the Proposed Project has been analyzed by Caltrain. This scenario would not require passing tracks. Under the - scenario, up to four HSR trains pphpd in addition to six Caltrain trains pphpd planned under the Proposed Project has been analyzed by Caltrain. This scenario would require one section of passing track (see discussion below). Additional Core Capacity projects (as described in the nine-party MOU for the High Speed Rail Early Investment Strategy or a Blended System in the San rancisco to San Jose Segment Known as the Peninsula Corridor of the Statewide High-Speed Rail System) including needed upgrades to stations, tunnel, bridges, potential passing tracks, other track modifications and rail crossing improvements including selected grade separations will be required to accommodate the mixed traffic capacity requirements of high-speed rail service and commuter services on the Caltrain corridor. However the specific Core Capacity projects have not been identified or defined at this time. These projects would be identified in future discussions and evaluations between CHSRA and Caltrain and other agencies. Core Capacity projects would be subject to separate, project-level environmental evaluation by the implementing agency/agencies. Table - presents some key conceptual assumptions that have been studied by Caltrain about Blended Service at this time. These assumptions are used in the cumulative impact analysis in this EIR. As noted in Table -, the cumulative analysis in this EIR presumes speeds for Blended Service up to 0 mph in light of the following considerations: The blended system has been simulated by Caltrain at speeds of up to 0 mph and shows a blended system to be viable. The 0 Partially Revised Program EIR for the Bay Area to Central Valley states the following: The HST could operate at maximum speeds of 00 mph along the Peninsula providing 0- minute express travel times between San rancisco and San Jose. (CHSRA 0f) CHSRA has confirmed that with speeds up to 0 mph, a 0-minute express travel time can be achieved between San Jose and San rancisco as required by Prop A (CHSRA 0a). If it is determined to be necessary to analyze speeds greater than 0 mph in the future, additional simulations will be performed to understand the viability and implications of the speed range identified by CHSRA in the 0 Partially Revised Program EIR. If speeds beyond 0 mph are ultimately proposed by CHSRA for the Caltrain corridor, track improvements may be necessary on the route to allow for an increase in top speed as well as any RA-mandated safety improvements, and they will be evaluated in the separate environmental document for evaluating HST service on the San rancisco Peninsula.

No estimate of blended system ridership with a Redwood City HSR station was included in the 0 Revised Business Plan (CHSRA 0a) or the Draft 0 Business Plan (CHSRA 0a). or the purposes of this EIR, all HSR ridership is assumed to be in addition to Caltrain ridership to analyze maximum potential traffic and other impacts due to increased ridership at combined HSR/Caltrain stations. CHSRA released its Draft 0 Business Plan (CHSRA 0a) in early ebruary 0 which presents higher ridership estimates than in the 0 Revised Business Plan; these estimates, which were draft at the time of the Draft EIR, have since been finalized and are shown in These estimates are provided in Table - below.

The concepts for station improvements at San rancisco (TTC), Millbrae, Redwood City, and San Jose Diridon Stations to accommodate HSR/Caltrain Blended Service are described below. San rancisco Transbay Transit Center (TTC) and Downtown Rail Extension (DTX) This is Project b in Table -. The Transbay Joint Powers Authority (TJPA), consisting of the City and County of San rancisco, the State of California, Alameda-Contra Costa Transit District, the JPB, and Caltrans (ex officio) is leading the planning and implementation of the TTC and Downtown Rail Extension (DTX) projects. The TTC/DTX is an independent project with multiple purposes of supporting Caltrain extension to downtown, improved transit services and coordination, as well as facilitating future high-speed rail service to the TTC. However, because it is an integral part of Blended Service, it is discussed in concert with the discussion of blended service. - IC 000.

23 A inal EIS/EIR for the DTX and TTC projects and the related redevelopment project (collectively, the Transbay Program) was completed in 00. A number of addenda have been completed since 00. TJPA is presently preparing a Supplemental EIS/EIR for certain changes to the Transbay Program as noted below. The Transbay Program consists of three components. A new, multi-modal transportation facility (the TTC) at the site of the former Transbay Terminal at irst and Mission Streets, which is currently under construction. A. -mile extension (the DTX) of Caltrain commuter rail service from its current San rancisco terminus at th and King Streets to the new TTC. Development of a mix of new and transit-oriented uses on publicly-owned property in the vicinity of the new TTC, including an estimated,000 new homes and mixed-use commercial development. Other features analyzed in the 00 inal EIS/EIR are an off-site bus storage facility, new bus ramps connecting to the Bay Bridge, a temporary bus facility for use during the construction of the TTC, and a reconfigured Caltrain layover yard. The new TTC has also been designed to serve the proposed HSR system. As part of the DTX project, the track between Caltrain s existing th and King Street terminal and the new downtown terminal would be electrified. Phase of the project consists of the TTC and is presently under construction with expected completion in approximately 0. Phase consists of the. -mile extension of Caltrain service to the TTC from the existing Caltrain terminal at ourth and King Street. The Supplemental EIS/EIR currently being prepared by TJPA will analyze proposed modifications to Phase, including the DTX track curvature entering the TTC, extension of platform rail levels to accommodate HSR requirements, an intercity bus facility, vent shaft enlargements and other minor refinements. The DTX work is on hold due to a funding gap and, thus, it appears likely that DTX will be completed after the Proposed Project. Scheduling is depending on funding availability. The prolonged delay of the DTX may require an interim high-speed rail terminal station at the th and King Station. As necessary, the CHSRA would evaluate this interim terminal station in a subsequent, project-level environmental impact analysis and document. The critical aspects for Blended Service are as follows: HSR service (up to four trains pphpd) would terminate or originate at the TTC with multiple dedicated platforms. The new line between the th and King Caltrain Station and TTC would be electrified as part of the DTX project. Caltrain service, once electrified, would extend to the TTC with the completion of the DTX. In concept, Caltrain service has been studied with split service between the th and King Caltrain Station and TTC, with some trains terminating at each station. San rancisco th and King Station and Approach Based on current planning, the HSR service would not stop at either the San rancisco th and King Caltrain Station or the future th and Townsend underground station (unless, as noted above, DTX - IC 000.

24 is delayed beyond the point that interim HSR service to th and King is possible in which case an interim terminal would operate at th and King). It would continue underground through the th and Townsend Station to the TTC. The surface station at th and King would be for Caltrain service terminating at that point. The underground th and Townsend Station would be a stop for Caltrain service terminating at the TTC. The platforms of the two stations would be connected vertically by stairs, escalators, and elevators to an underground mezzanine. Pursuant to current DTX designs, DTX tracks would begin just north of th Street with new tracks and sidings as the alignment approaches the th and Townsend and the th and King Stations. The surface tracks and underground tracks would separate at approximately Berry Street. The Proposed Project would electrify the th and King Station and yard, including the existing six platforms and tracks. This would allow for electrified operations to start in At present, the Proposed Project does not include funding to reconfigure the station and yard. The station configuration at the ourth and King Station assumed covered in the TJPA 00 EIS/EIR and approved by the TJPA would reconstruct the storage yard with included three surface platforms and six tracks on the southern portion of the existing facility and add a new one-platform underground station on the northern portion near Townsend and ourth Street. TJPA indicated in its comment on the PCEP Draft EIR that full platform reconfiguration is not part of DTX. Although the station reconfiguration was assumed in the original 00 EIS/EIR project description, TJPA clarified that full platform reconfiguration is assumed to be a separate project by others. A potential future project (currently unfunded) to reconfigure the th and King platforms is described separately below under discussion of Caltrain projects. The schedule for completion of the DTX has not yet been determined and funding for platform reconfiguration is uncertain at this time, thus, it is possible that station reconfiguration, if appropriate, will occur sometime after 00 0, when funding is available. Should funding become available prior to 00 0, it may be possible to reconfigure the station and yard prior to electrification. Millbrae Station The most recent design for a HSR station at Millbrae was presented in the 00 HSR Alternatives Analysis for the Peninsula corridor and would include two dedicated HSR tracks and platforms atgrade. The Caltrain station would be split level with one platform at-grade and one below-grade (CHSRA 00c). A grade separation at Center Street in Millbrae would be necessary because of the changes at the Millbrae Station (CHSRA 00a). The station design will need to be reevaluated to ensure appropriate scale for the blended system. Redwood City Station No decision has been made by CHSRA or Caltrain or any other party that there will be a Redwood City Station. Based on the designs in the 00 HSR Alternatives Analysis, the Redwood City Station could be either elevated or below-grade in a trench. If there is a Redwood City HSR station that is elevated or below-grade, then there would also be grade separations at the nearby street crossings (CHSRA 00a). The station design will need to be reevaluated to ensure appropriate scale for the blended system. The Mission Bay Drive crossing would remain at-grade based on current designs. - IC 000.

25 San Jose Diridon Station The San Jose Diridon Station would have dedicated platforms for HSR. The design of the station improvements has been the subject of prior and ongoing study. CHSRA is currently in the process of refining design alternatives for the HSR alignment through San José. These alternatives will be evaluated by the CHSRA when they prepare the San José to Merced and/or San rancisco to San José HSR EIR/EIS documents. At present, potential designs for the San Jose Diridon Station show either an elevated or a belowgrade station. Depending on the vertical placement of the station, the approaches from the south and the north to the station could be in a tunnel or on an aerial structure. The approaches would likely transition from two tracks to four tracks as they approach the station to allow for four tracks in the station (CHSRA 00a, 00b, 00e). Additional Trackage Merging HSR Tracks from Diridon to Santa Clara Blended Service would include two new dedicated HSR tracks between the San Jose Diridon Station and just north of the Santa Clara Caltrain Station (CHSRA 00b). The dedicated tracks would proceed northward on either an aerial structure or in a tunnel from the San Jose Diridon Station and merge into middle of the Caltrain mainline at grade north of Control Point (CP) De La Cruz which is just north of the Caltrain Santa Clara Station (CHSRA 00b). Passing Tracks As described above, the - scenario would require passing tracks. It is important to note that no decisions have been made about the locations of passing tracks; the subsequent design and environmental process will define the actual proposed passing track locations. The locations studied to date are identified to support a proof of concept approach only. Proposed passing track locations could include other variations than those studied to date. However, because the locations analyzed in the capacity studies completed to date are the only locations that have been studied, these locations are used in this EIR to disclose at a very general level what the impacts of passing tracks may be with Blended Service. Passing tracks would be added to the existing tracks in limited segments of the corridor to be used by HSR trains to bypass Caltrain trains stopping at stations. The conceptual information used in this EIR about passing tracks comes from two planning studies completed in 0 and 0. Caltrain/California HSR Blended Operations Analysis (LTK 0). Caltrain/California HSR Blended Operational Analysis Supplemental Analysis Requested by Stakeholders: Service Plan/Operations Considerations Study (LTK 0). Passing tracks required for operational overtakes (i.e., one same-direction train passing another) would improve the integration of Caltrain and HSR services, avoid either service being substantially delayed at a passing track location by the other service, and are required to support the / scenario. The operational studies completed by Caltrain (LTK 0; LTK 0) provide further information on the overtake s operational requirements; the reader is referred to those studies for further detail. ive potential overtake locations have been conceptually defined and are shown in igure -.: - IC 000.
