San Francisco, CA — This month, the San Francisco County Transportation Authority (SFCTA) is celebrating the 10 year anniversary of Proposition K, the city’s half-cent transportation sales tax that passed with 75% voter approval in November, 2003. The Prop K program generates about $88 million per year and funds a range of transportation improvements for multiple transit operators and travel modes throughout San Francisco.

The SFCTA Board is comprised of the 11 members of the Board of Supervisors and has allocated over $1 billion in Prop K funds since 2003:            

  • Over $420 million has been invested in major capital projects (e.g., Transbay Transit Center, Presidio Parkway, Central Subway, Caltrain Electrification, Van Ness and Geary Bus Rapid Transit); and
  • Another $456 million supported citywide and neighborhood programs (such as street resurfacing, traffic calming, new transit vehicles, and pedestrian and bicycle safety improvements); and 
  • $119 million was provided for operations and maintenance programs (primarily for paratransit).

“Proposition K’s impact has reached every neighborhood in San Francisco,” said John Avalos, Chair of the SFCTA Board. “We have been extremely fortunate in San Francisco to have this dedicated source of local transportation funding to improve transportation options for all, at a time when state and Federal resources are shrinking. The Transportation Authority works hard to leverage these funds and to provide transparency and accountability to the voters who supported this critical program.” The Prop K program attracts four to seven times its weight in other funds, when combined with regional, state and federal dollars.

To keep the public informed about the sales tax program, the SFCTA recently launched MyStreetSF, an interactive project map that shows nearly 1,000 active and completed projects that it has funded. Residents can now go online to to find out how Prop K dollars have been spent in their neighborhood.

The new website has garnered interest across the city in the $12 billion long-range countywide transportation plan that the SFCTA is  developing, known as the San Francisco Transportation Plan (visit The SFTP has an Early Action Program that sets out transportation improvements for every district over the next 5 years. The SFCTA Board will adopt the Early Action Program, along with the SFTP, this winter.

“As the City moves forward, it is extremely important that we continue invest in our transportation infrastructure,” said Tilly Chang, Executive Director of the SFCTA. “Complete streets and well-maintained transit are the keys to enhancing pedestrian safety and economic development in every neighborhood. Today, as we prepare to adopt the San Francisco Transportation Plan and to coordinate with the Mayor’s Transportation Task Force on a new era of investment, we are focused with our city partners on delivering the next generation of transportation improvements for San Francisco.”
