7 Executive Summary Summary Description of the Proposed Project The Vasona Corridor Light Rail Transit (LRT) Project was a 6.8-mile extension of Santa Clara County s LRT system from downtown San José through the City of Campbell and into the Town of Los Gatos. The project was analyzed in an Environmental Impact Statement (EIS) and Environmental Impact Report (EIR), which were approved in 2000 by the Federal Transit Administration (FTA) and the Santa Clara Valley Transportation Authority (VTA), respectively. Subsequent to its approval, the project was constructed between downtown San José and the Winchester Station in Campbell. The southernmost portion of the project (i.e., the 1.6-mile segment between the Winchester Station and the Vasona Junction Station in Los Gatos) was not constructed due to lack of sufficient funding. The analysis of the extension project, including design changes since approval of the EIS/EIR, is presented in this Supplemental EIR/Environmental Assessment (SEIR/EA). The proposed Vasona Corridor LRT Extension Project would complete the originally planned Vasona Corridor with a 1.6-mile extension of the Vasona LRT Line. The extension would begin at the existing Winchester Station in Campbell and continue within the VTA right-of-way to the Town of Los Gatos. A number of design changes to the approved project are now proposed. Proposed changes to the approved project are as follows: 1. Construction of a double set of LRT tracks from Winchester Station to Vasona Junction Station and relocating the existing freight track east of the new LRT tracks within the existing right-of-way; 2. Expansion of the park-and-ride lot and bus transit center at the Winchester Station; 3. Installation of an electrical power substation at the southeast corner of the expanded Winchester Station park-and-ride lot; 4. Construction of an at-grade pedestrian crossing east of the Winchester Station to provide access to the station from the adjacent Avalon Campbell Apartments. 5. Construction of the Hacienda Station in the originally identified location with an optional park-and-ride lot at the northeast corner of Winchester Boulevard and Hacienda Avenue; 6. Construction of the Vasona Junction Station in the originally identified location and construction of a park-and-ride lot with two alternate configurations on an adjacent parcel currently owned by the Santa Clara Valley Water District (SCVWD); 7. Installation of an electrical power substation either on the west side of Winchester Boulevard, immediately south of the State Route 85 on-ramp, or in the southeast corner of the park-and-ride lot; and Vasona Corridor Light Rail Transit Extension vi Final SEIR/EA

8 8. Extension of six of the eight existing LRT station platforms along the Vasona Corridor (Winchester, Campbell, Hamilton, Bascom, Fruitdale, and Race Street) to 280 feet to accommodate three-car trains. The Vasona Corridor LRT Extension Project would be implemented in two phases based on funding and projected ridership. Phase 1 would include all project features listed above except the Hacienda Station and optional Hacienda park-and-ride lot. The Hacienda Station (with or without the park-and-ride lot) would be constructed in Phase 2, contingent on sufficient funding and ridership. The station platform extensions may also be deferred to Phase 2. A detailed project description is provided in Chapter 2.0 of this document. The project is included in the adopted Santa Clara Valley Transportation Plan 2035 (VTP 2035), as well as the adopted San Francisco Bay Regional Transportation Plan 2035 (T-2035). Per the T-2035 Plan, the estimated capital cost to construct the Vasona Corridor LRT Extension Project is $146 million. However, subsequent to publication of T-2035 in 2009, VTA has updated the costs of the project based on discrete project features included in both Phase 1 and Phase 2. The project is now anticipated to cost approximately $176 million to complete design and construction for both phases of the project. Funding for the project will include the Measure A Program, which is a local ½-cent sales tax designated for transportation improvement projects. Other funding sources have yet to be determined, but may include a combination of federal and/or state transportation monies. Public Review of the Draft SEIR/EA The Draft SEIR/EA was made available for public review and comment from November 20, 2012 to January 7, 2013, with a public hearing held at the Campbell Public Library on December 4, All comments on the Draft SEIR/EA, both written and oral, are responded to in Chapter 9 of this document. A copy of each written comment is contained in Appendix L. A copy of the public hearing transcript, which contains the verbatim oral comments, is contained in Appendix M. This document also reflects changes made to the text of the Draft SEIR/EA in response to the comments that were received. Text additions are underlined and text deletions are indicated with a strikeout. The most notable changes that occurred are as follows: The addition of an alternate design for the Vasona Junction park-and-ride lot that would preserve two large oak trees.

Summary of and Mitigation The following discussion summarizes the environmental impacts of the proposed Vasona Corridor LRT Extension Project. A detailed discussion of the environmental setting, impacts, and mitigation measures is provided in Chapter 4.0 of this document. Since this is a joint NEPA and CEQA document, the analysis of each subject in this document concludes with both a NEPA finding and a CEQA determination. When discussing NEPA findings, the terminology used in this analysis includes no adverse effect and adverse effect. When discussing CEQA determinations, the terminology used in this analysis includes no impact, less than significant impact, and significant impact.

Less Than Significant Impact per CEQA; No Adverse Effect per NEPA (See Section ) The loss of trees along the project alignment would not be a significant visual impact. Less Than Significant Impact per CEQA; No Adverse Effect per NEPA (See Section ) Implementation of the proposed project will not subject people or new development to flooding hazards. Less Than Significant Impact per CEQA; No Adverse Effect per NEPA (See Section ) Development of the approximately two-acre Vasona Junction park-and-ride lot site, which is vacant, would not require upgrades to the existing infrastructure to support the project. Less Than ) With implementation of a Stormwater Control Plan, the project would not violate any adopted water quality standards or waste discharge requirements. Less Than ) The proposed platform extensions would have a less than significant long-term water quality impact. Less Than Significant Impact per CEQA; No Adverse Effect per NEPA (See Section ) Construction of the proposed Vasona Junction park-and-ride lot and optional Hacienda park-and-ride lot could temporarily impact the water quality of Los Gatos Creek. Temporary Significant Impact per CEQA; Adverse Effect per NEPA (See Section ) Hydrology and Water Quality Project-specific mitigation measures will be implemented during all phases of construction to reduce construction-related water quality impacts. Less Than Significant Impact With Mitigation per CEQA; No Adverse Effect With Mitigation per NEPA (See Section Vasona Corridor Light Rail Transit Extension ix Final SEIR/EA

11 Relocation of the freight track and installation of the double LRT Tracks would not substantially increase sediment or contaminants entering the local storm drainage system. Less Than Significant Impact per CEQA; No Adverse Effect per NEPA (See Section ) With full compliance of permit regulations, the proposed project will have a less than significant hydromodification impact. Less Than ) Even with a substantial increase in impervious surfaces on the Vasona Junction park-and-ride lot site, the project would have a less than significant impact on the groundwater aquifer. Less Than ) Implementation of the proposed project will not put any persons in danger from inundation due to dam failure. Less Than ) Implementation of the proposed project would result in the loss of native coast live oak trees that provide habitat for bird species on the Vasona Junction park-andride lot site. Significant Impact per CEQA; Adverse Effect per NEPA (See Section ) Biological Resources for the full list of mitigation measures) The California coast live oak trees on the Vasona Junction park-and-ride lot site (measuring 18 inches in diameter or greater) will be replaced in-kind and on-site at a 5:1 ratio. Replacement trees will be a local ecotype grown from propagules collected from parent plants growing in the Guadalupe watershed as close to the project site as possible. Acorns will also be collected from the oaks on the park-and-ride site. either 15-gallon or 24-inch box specimens and will be purchased from local genetic stock. Replacement trees will be planted along the eastern property line. If there is not sufficient room available to plant all the replacement trees, the trees will be planted as near the riparian corridor as possible. Replacement trees will be irrigated for a minimum of two years. If sufficient planting areas are not available on-site, the oak trees Vasona Corridor Light Rail Transit Extension x Final SEIR/EA

12 Construction of the proposed Vasona Junction park-and-ride lot during nesting season could result in the loss of individual yellow warblers, their nests, their eggs, and/or the loss of active nests of other bird species. Significant Impact per CEQA; Adverse Effect per NEPA (See Section ) Construction of the proposed Vasona Junction park-and-ride lot could impact the aquatic species occupying Los Gatos Creek. Significant Impact per CEQA; ) may be planted along the upper banks of the Los Gatos Creek riparian corridor directly adjacent or within close proximity to the Vasona Junction park-and-ride lot site. If the alternate design for the Vasona Junction park-and-ride lot is selected, which would preserve two large California coast live oak trees located near the center of the site, the following measure will be implemented in order to avoid harm to the trees: An arborist will be present to monitor subsurface work with a radius around the trunks equivalent to the canopy radius plus 50%. If large roots are exposed, the arborist will specify measures to be implemented to protect them. Less Than Significant Impact With Mitigation per CEQA; No Adverse Effect With Mitigation per NEPA. When possible, construction activities will occur outside the breeding season for local bird species, which is February through August. Possible nesting areas (i.e., bushes, trees, grass, burrows) that will be removed as part of the project will be removed between September and January to preclude nesting. If it is not possible to schedule demolition and construction between September and January, pre-construction surveys for nesting birds will be completed by a qualified ornithologist to ensure that no nests will be disturbed during project implementation. If an active nest is found sufficiently close to work areas to be disturbed by construction, the ornithologist, in consultation with CDFG, will determine the extent of a constructionfree buffer zone to be established around the nest, typically 250 feet, to ensure that raptor or migratory bird nests will not be disturbed during construction. Less Than Significant with Mitigation per CEQA; No Adverse Effect With Mitigation per NEPA Stormwater control BMP s will be implemented during all phases of construction consistent with the measures listed in Section 4.5, Hydrology and Water Quality of this SEIR/EA.
