What Transbay Joint Powers Authority does
The Transbay Joint Powers Authority (TJPA) is a California joint powers authority established in 2001 to plan, develop, and operate the Transbay Transit Center program in San Francisco. It was created by a joint powers agreement between the City and County of San Francisco and regional transportation agencies to replace the original 1939 Transbay Terminal with a modern multi-modal regional hub. TJPA is governed by a Board of Directors and supported by a 15-member Citizens Advisory Committee, with leadership including Executive Director Maria Ayerdi-Kaplan and CFO Sara Gigliotti. The authority operates as a public agency and does not have shareholders, equity investors, or equity-based ownership.
TJPA's core product is the Salesforce Transit Center, a 1+ million square foot multi-modal hub that connects nine transit systems—Caltrain, AC Transit, Muni, BART, Golden Gate Transit, WestCAT, and planned California High-Speed Rail—along with the 5.4-acre Salesforce Park (a living rooftop with 600 trees and 16,000 plants) and on-site retail and wellness services. Its major infrastructure project is The Portal/DTX (Downtown Rail Extension), with $730 million already invested in the underground Train Box and an estimated $7.5 billion required to complete the extension of Caltrain and California High-Speed Rail into downtown San Francisco. The broader Transbay Program also encompasses over 4,000 planned housing units and 100,000 square feet of planned retail in the surrounding neighborhood.
TJPA's business model is government funding, not commercial revenue generation. Cash flow is sourced from federal grants, state funds (including Regional Measure 2 bridge toll revenues), local transportation measures, and ancillary retail lease income from the Transit Center. As a public agency, TJPA does not charge individual transit riders; its "customers" are the partner transit agencies (Caltrain, CHSRA, AC Transit, Muni, BART, Golden Gate Transit, WestCAT) and the public. The Salesforce Transit Center opened in 2018 and The Portal/DTX remains the central multi-year capital initiative.
