Treasure Island development visualization

Treasure Island is a man-made island, originally constructed for the Golden Gate International Exposition of 1939. Located in the San Francisco Bay between the cities of Oakland and San Francisco, the Island was a US Navy base until 1993.

The City of San Francisco established the Treasure Island Development Authority in 1997 to redevelop the Island as a new neighborhood in the city of San Francisco. Today, Treasure Island is home to approximately 2,000 people and numerous businesses and organizations.

When redeveloped, Treasure Island will include 8,000 homes, 500 hotel rooms, 550,000 square feet of office and retail use and open space for recreation.


  • Transportation on-Island will be designed to foster a safe walking and biking environment
  • Transit services will provide an appealing alternative to driving
  • Residents and hotel guests will be required to purchase pre-paid transit passes
  • Single-occupancy vehicle trips will be discouraged through a congestion pricing program
  • Congestion pricing program revenues will pay for alternative modes such as transit, walking, and bicycling

Transportation Affordability Plan (TAP)

  • This plan is intended to provide a transportation cost-reduction program for anyone living in below market rate housing, as well as anyone living on Treasure Island for more than five years.
  • Initial TAP strategies include:
    • Transit fare discounts
    • Toll credit for transit trips
    • Car share memberships
    • Bay area bike share membership
    • Deliveries and rideshare subsidies
    • Subsidizing one round-trip toll payment for longtime residents
  • Proposed/recommended strategies will likely be phased in based on the number of low-income households and workers on the Island over time.
  • Existing residents are eligible for these benefits.  

Transportation Demand Management (TDM)

  • The goal of the TDM program is to have at least 50% of the trips to and from Treasure Island/Yerba Buena Island be via modes other than solo drivers.
  • Initial strategies include:
    • Mandatory Pre-Paid Transit Pass Program
    • Car and Bike Share Program
    • Carpool and Vanpool Ridematching Services
    • Guaranteed Ride Home Program
    • Free On-Island Shuttle
    • On-off Island Shuttle / Vanpool
  • These TDM strategies are going to be phased in over the course of the years of development in an effort to achieve the 50% mode share goals.

Transit Pass

  • The goal of the transit pass is to make transit affordable and accessible to residents.
  • The transit pass  will be loaded on Clipper cards, and will have functions unique to Treasure Island/Yerba Buena Island.
  • Basics of the Transit Pass include:
    • Mandatory transit pass for new (market-rate) residents
    • Multi-operator functions

SFMTA Parking Policy

  • The goals of the parking management policy are as follows:
    • Encourage walking, transit, and biking
    • Make parking more accessible
    • Ensure parking is available for those who need it
    • Implement parking management before and as development takes place
    • Help pay for new transit
  • As each part of the Island is rebuilt, all publicly available on and off street parking in rebuilt areas will be priced and managed to help achieve the overall goals of the transportation plan.
  • All parking fees paid on TI will go back to funding the new transit to serve TI. This is a unique benefit that only TI gets—parking charges can ONLY be spent to benefit TI.
  • With each new residential building that is built, all residential parking is unbundled from the units. It is anticipated that most of the residential parking (approx. 80-85%) will be provided in subterranean garages underneath residential buildings.
  • All other parking on the Island, both on-street and off-street lots and garages, will be publicly available.
  • The SFMTA Board is expected to adopt this policy in Spring 2017. It has already been adopted by the Treasure Island Development Authority and the Board of Supervisors, as part of the Transportation Implementation Plan, the Environmental Impact Report and the Treasure Island Development Agreement.
