The Treasure Island Mobility Management Agency (TIMMA) was created to develop a transportation plan to serve the residents, businesses and visitors of Treasure Island and Yerba Buena Island. The neighborhoods are being developed to include 8,000 new homes, 500 hotel rooms, 550,000 square feet of office and retail use and open space.

TIMMA is governed by the TIMMA Board, which is comprised of the San Francisco Board of Supervisors. TIMMA staff work for the San Francisco County Transportation Authority.

TIMMA’s goal is to design a transportation plan that serves as a model for sustainable development, offering ways to get around that are not dependent on cars. The initiative also extends many benefits such as new ferry and bus multi-use recreational paths, bike lanes, pedestrian-only streets, additional open space for recreation and a free on-Island shuttle.

Goals of the project include:

  • Reducing congestion
  • Ensuring that at least 50% of trips to and from the Island are using modes other than solo car trips
  • Making transit affordable and accessible
  • Encouraging a walking, transit and biking environment
