What is happening on Treasure Island?

The closure of the Naval Station on Treasure Island in 1997 opened the door for the island to become San Francisco’s newest neighborhood. Developing new housing for San Francisco was a priority from the very beginning and is the primary focus of the approved development plan.  With an emphasis on affordable housing and car-light living, the current Treasure Island plans will be a great model for sustainable development.

When will it happen?

After many years, things are finally moving on Treasure Island! The developer recently received approval for their first Major Phase of development. The tentative timeline is that the first homes on Yerba Buena Island will be open in 2018, with Treasure Island homes to follow a year later.

What will it consist of?

The Project provides a new, high-density, mixed-use community with a variety of housing types, a retail core, open space and recreation opportunities, on-site infrastructure, and public and community facilities and services. In all, there will be up to 8,000 residential units; up to 140,000 square feet (sq. ft.) of new commercial and retail space; approximately 100,000 sq. ft. of new office space; up to 500 hotel rooms; approximately 300 acres of parks and open space; bicycle, transit, and pedestrian facilities; a ferry terminal and intermodal transit hub; and new and/or upgraded public services and utilities, including a new or upgraded wastewater treatment plant.

What is the developer paying for?

Quite a bit. First of all, the developer is preparing the islands for development by demolishing obsolete buildings and performing ground improvements. Then, they’ll design, build, and pay for all the new utilities, streets and streetscapes, trails, parks, and community facilities. The developer will provide numerous public benefits, including affordable housing subsidies, subsidies for school and childcare facilities, a joint police/fire station, a community center, and many others. They’ll also be subsidizing the new transportation options on the island, including bus, ferry, a free on-island shuttle, and bike share.



What is TIMMA?

Early on, the SFCTA planners and Treasure Island stakeholders identified the need to think comprehensively about the transportation options that will ensure that redevelopment of Treasure Island is a success. TIMMA, which stands for the Treasure Island Mobility Management Agency, was created to coordinate the transportation needs of the island, including working with multiple transit agencies.

Who is TIMMA?

Staff of the San Francisco County Transportation Authority (SFCTA) currently wear two “hats”—as both SFCTA and TIMMA staff. TIMMA is governed by the TIMMA Board, comprised of the San Francisco Board of Supervisors. Currently the chair of the TIMMA Board is Commissioner Jane Kim.

What is TIMMA currently doing?

TIMMA is preparing policy recommendations for the congestion pricing. Over the next year preparing for implementation of the mobility program, such as designing a transit pass for the island and coordinating with bike share implementation will be studied.

How can I learn more about the plans that led to the Mobility Management Agency?

TIMMA was formed in 2008 when the California State Legislature passed AB 981, authorizing the formation of TIMMA, to manage a congestion pricing plan in conjunction with the Treasure Island Transportation Improvement Plan

How can I get involved in the decisions that are made for Treasure Island transportation?

The public is always welcome to attend TIMMA Board meetings, meetings of the Treasure Island Development Authority (TIDA), and meetings of the TIDA Citizens Advisory Board (TIDA CAB). For updates on our planning work and to hear about upcoming outreach events, you can sign up for our mailing list at the bottom of the page.



What is the congestion toll?

The Treasure Island Transportation Implementation Plan (TITIP) calls for the TIMMA to implement a congestion toll for vehicle traffic from Treasure Island and Yerba Buena Island onto and off of the San Francisco-Oakland Bay Bridge. This toll was identified to help mitigate traffic impacts from the new neighborhood onto the bridge, particularly during peak hours, and to generate revenues to help fund alternate modes of transit. 

How much will the congestion toll be and when will it be in effect?

The tolling structure is still being studied, but will likely vary between $3 and $5, depending on the time of day. During congested periods, the toll will be higher. When there is less congestion, the toll will be lower. By having different congestion tolls by time of day, we can encourage people to use the San Francisco-Oakland Bay Bridge when it is less congested, reducing delay for regional commuters. The congestion toll will begin with the opening of the first new developments on Treasure Island and Yerba Buena Island, currently scheduled for Winter 2018-2019.

How does this congestion toll relate to the Bay Bridge toll?

Drivers who have already paid a San Francisco-Oakland Bay Bridge toll will not pay the full Treasure Island congestion toll. For example, someone who drives from the East Bay to Treasure Island will not pay the full congestion toll going onto Treasure Island because they’ll receive partial credit for paying the San Francisco-Oakland Bay Bridge toll. Someone who drives from San Francisco to Treasure Island will only pay the TI congestion toll. And drivers who travel on the San Francisco-Oakland Bay Bridge who do not visit Treasure Island will never pay the TI congestion toll.

Why will there be a congestion toll?

The new neighborhood on Treasure Island will have more residents than many existing San Francisco neighborhoods, plus office and retail. These new residents and employees will need to travel between the island and the rest of the Bay Area. To accommodate the new neighborhood quality transit services will be required to avoid adding substantial traffic to the already congested San Francisco-Oakland Bay Bridge. The congestion toll will provide a financial incentive to drivers to get out of their cars, particularly during peak hours, and will directly fund the new transit services, as a convenient and viable alternative to driving.  

How will the congestion toll be collected?

The congestion toll will be collected through the use of FasTrak exclusively. Drivers will not be able to pay with cash and the streamlined system will not include congestion toll booths or require vehicles to stop. Drivers without FasTrak will receive congestion toll bills electronically or by mail to the address of the vehicle registration.

Are there options for low-income residents?

Yes. A new program is being developed for residents of Treasure Island who have low incomes. The program will offer discounted transit passes, a transit-for-toll credit program, and other benefits.

Who is exempt from the congestion toll?

Shuttles/vanpools and transit and any person walking or biking from the Bay Bridge East Span Bike Path would be exempt.

When will the congestion toll begin?

The congestion tolling program will be implemented when there are a significant number of new housing units on Treasure Island, currently anticipated for the winter of 2018-2019.



What new transit services will the congestion toll pay for?

There will be a new ferry service to the Ferry Building in San Francisco, Muni service to the San Francisco Transbay Terminal and Civic Center, AC Transit bus service to BART in Downtown Oakland, and a free on-island shuttle that will circulate around Treasure Island and Yerba Buena Island.  While passenger fares will pay for some of the cost of this new transit, the revenues generated by the congestion toll will also directly fund these and other transportation improvements on the Island, such as bike share and chare share.

Why is a ferry being proposed?

In order to reduce impact on the San Francisco-Oakland Bay Bridge and meet the development's sustainability goals, there will need to be new and expanded transit options.  A survey of current residents found that a ferry service to San Francisco was a top priority, along with increase frequency of Muni services.

How much will the bus and ferry cost to ride?

We don't know everything yet. One thing we're sure about is we want transit to be a "no-brainer" decision—affordable for everyone, easy to access, and convenient. Towards that end, we know that we want to provide commuter passes for frequent riders, and we're working with all the transit agencies to determine how to make that happen.



How will I get around without a car on Treasure Island?

All of the homes will be within a 15 minute walk (or a 5-minute bike ride) of the Island Center neighborhood where the bus and ferry terminal will be located and retail outlets will be concentrated.  Also planned is a free on-island shuttle with stops in every neighborhood.

How will the design encourage walking and biking?

In addition to a network of bike and pedestrian trails encircling and crisscrossing the Island, in the west side and residential neighborhood, cars will share the right-of-way with bikes and pedestrians in a Shared Public Way.  These are street that will feel more like plazas, characterized by limited vehicle speeds, no parking, few loading zones, and no garage entrances.  The east side neighborhood will be bisected by a greenbelt where vehicles are prohibited altogether.

Will there be bike share?

Treasure Island will be an amazing place for bike share expansion and we're coordinating with our public and private partners to enable timely implementation of bike share on Treasure Island.  In addition, to bike share in the future, there are existing long-term bike rental opportunities on the Island.

What trail opportunities will there be?

There will be an extensive network of trails on Treasure Island and Yerba Buena Island, offering residents and visitors ample opportunity to enjoy the views and nature of the Bay.

When will the Bay Bridge bike-ped path open?

We expect the Bay Bridge Bicycle and Pedestrian Path to open in September of 2016.  For more information, visit the Bay Bridge Bicycle and Pedestrian Path website
