Document Description
The project sponsor, the San Francisco Municipal Transportation Agency (SFMTA), proposes to replace the Potrero Trolley Coach Facility at 2500 Mariposa Street (Potrero Yard) in the northeast portion of San Francisco’s Mission District near the South of Market and Potrero Hill neighborhoods. The proposed project would demolish the existing transit facility originally constructed in 1915 which has been identified as a historical resource for purposes of CEQA. The project is intended to accommodate the expansion of the SFMTA’s transit vehicle fleet in a new replacement structure that would include space for bus parking and circulation (up to 213 buses); SFMTA maintenance, operation, and administrative uses; and joint development uses (commercial and residential). The new, approximately 1,300,000 gross-square-foot structure would occupy the 4.4-acre site and rise to heights ranging from approximately 75 to 150 feet. The new structure would contain a three-level, approximately 75-foot-tall replacement transit facility (728,000 gsf) plus a mix of commercial (33,000 gsf) and residential uses (575 residential units and 544,000 gsf) in the remainder of the project as part of a joint development program between SFMTA and a private project co-sponsor. The joint development program would include a ground-floor commercial use and residential entry lobbies, with integrated residential and transit facility uses on the second through sixth floors of the three-level replacement transit facility. The majority of residential development would be atop the replacement transit facility on the 7th to 13th floors.
