A Final Environmental Impact Report/Environmental Impact Statement (EIR/EIS) has been prepared by the California Department of Transportation (Caltrans) and the San Francisco County Transportation Authority (the Authority) for the Yerba Buena Island (YBI) Ramps Improvement Project. Caltrans is the lead agency pursuant to National Environmental Policy Act (NEPA) and the Authority is the lead agency, pursuant to the California Environmental Quality Act (CEQA). Project Location and DescriptionYBI is located in the San Francisco Bay, approximately halfway between Oakland and San Francisco, and is accessible by vehicles only via the San Francisco-Oakland Bay Bridge (SFOBB), which is part of Interstate 80 (I‑80). The SFOBB is a critical link in the interstate network, providing access between San Francisco and the East Bay. YBI and the SFOBB also provide access to Treasure Island (TI), which lies to the north of YBI. YBI and TI are accessed by on-and off-ramps located on the upper and lower decks of the SFOBB. The SFOBB and the associated on- and off-ramps provide the only land access to the active U.S. Coast Guard facilities located on the southern side of YBI. The proposed project is located between Post Mile (PM) 7.6 and PM 8.1 starting at the east portal of the YBI tunnel and ending before the SFOBB Transition Structure. The proposed project would replace the existing westbound on-ramp and the westbound off-ramp located on the eastern side of YBI with a new westbound on-ramp and a new westbound off-ramp that would improve the functional roles of the current ramps. The YBI Ramps Improvement Project is separate and independent of both the SFOBB East Span Seismic Safety Project currently under construction, and the Treasure Island and Yerba Buena Island (TI/YBI) Redevelopment Plan, which is currently undergoing its own independent environmental review process. Project PurposeThe purpose of the proposed project is to improve:
Final EIR/EIS OverviewThe Authority in cooperation with Caltrans has prepared a Final EIR/EIS. The Final EIR/EIS presents the environmental existing conditions, impacts from construction and operation of the alternatives, and suggested mitigation measures to reduce or eliminate adverse impacts. The information is grouped by environmental impact category and a summary is provided of impacts and mitigation measures to reduce adverse impacts to less-than-significant levels. The project proponent would apply the mitigation measures during design, construction and operation of the facility. The Final EIR/EIS found that implementation of the proposed project would result in significant unavoidable environmental effects related to visual/aesthetics and cultural resources.
