What are the plans for 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. With an emphasis on affordable housing and transit-oriented living, the new Treasure Island neighborhood will be a model for sustainable development.

Learn more about development plans for Treasure island at the Treasure Island Development Authority’s website.

When will the development happen?

After many years of planning, things are finally moving on Treasure Island. The developer has received approval for the first major phase of development. The tentative timeline is that the first homes on Yerba Buena Island will be open in 2020, with homes on the neighboring Treasure Island to follow a year later.

What is the developer paying for?

The developer is preparing the islands for development by demolishing old 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 more. They’ll also subsidize a portion of the new transportation options on the island, including the bus, ferry, a free on-Island shuttle, and bike share.


What is the Treasure Island Moblity Management Agency?

Early on, Transportation Authority planners and Treasure Island stakeholders identified the need to develop a comprehensive transportation plan for the island. The Treasure Island Mobility Management Agency, also known as TIMMA, was created to coordinate transportation for the island in collaboration with regional transit agencies.

Transportation Authority staff currently wear two hats as both Transportation Authority and Treasure Island Mobility Management staff. The agency is governed by the Treasure Island Mobility Management Board, which is comprised of the San Francisco Board of Supervisors. Currently the chair of the Board is Commissioner Jane Kim and the Vice Chair is Commissioner Norman Yee.

What is the Treasure Island Mobility Management Agency currently doing?

The Treasure Island Mobility Management Agency is preparing policy recommendations for congestion pricing, designing a transit pass for the Island, and developing an affordability program for residents.

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

The Treasure Island Mobility Management Agency was formed in 2008 when the California State Legislature passed Assembly Bill 981, authorizing its formation, to manage a congestion pricing plan in conjunction with the Treasure Island Transportation Implementation Plan.

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

The public is always welcome to attend Treasure Island Mobility Management Agency Board meetings, meetings of the Treasure Island Development Authority, and meetings of the Treasure Island Development Authority Citizens Advisory Board. 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 calls for the Treasure Island Mobility Management Agency to implement a congestion toll for vehicle traffic from the San Francisco-Oakland Bay Bridge to Yerba Buena/Treasure Island. This toll was identified to help mitigate traffic impacts from the new neighborhood with the bridge, particularly during peak hours, and to generate revenues to help fund alternate modes of transit.

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 space. These new residents and employees will take tens of thousands of additional trips between the island and the rest of the Bay Area each day. 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 much will the congestion toll be and when will it be in effect?

The toll 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 2021.

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 downtown San Francisco to Treasure Island will only pay the Treasure Island congestion toll. And drivers who travel on the San Francisco-Oakland Bay Bridge who do not visit Treasure Island will not pay the Treasure Island congestion toll.

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 toll booths or require vehicles to stop. Drivers without FasTrak will receive toll bills electronically or by mail to the address of their vehicle registration.

Are there options for low-income residents?

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

Who is exempt from the congestion toll?

Registered shuttles/vanpools, transit vehicles, and any person walking or biking from the Bay Bridge East Span Bike Path will 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 2021.



What new transit services will the congestion toll pay for?

There will be 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 car 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 ferry service to downtown San Francisco was a top priority, along with an increase in frequency of Muni service.

How much will the bus and ferry cost to ride?

We haven’t determined pricing yet. We want transit to be a "no-brainer" decision—affordable for everyone, easy to access, and convenient. We also want to provide commuter passes for frequent riders and we're working with 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 five-minute bike ride of the Island Center neighborhood where the bus and ferry terminal will be located and retail outlets will be concentrated. There will also be a free on-island shuttle which circulates throughout the island.

How will the design encourage walking and biking?

In addition to a network of bike and pedestrian trails encircling and crisscrossing the island, cars will share the right-of-way with bikes and pedestrians in a “Shared Public Way” on the west side and in residential neighborhoods. These are streets that will feel more like plazas, characterized by limited vehicle speeds, no parking, few loading zones, and no garage entrances. Other models of Shared Public Ways include Sevilla, Spain’s Calle San Jacinto and London’s Exhibition Road, which mix low volume automobile traffic with pedestrians and bicyclists. Treasure Island’s east side neighborhood will be bisected by a greenbelt where vehicles are prohibited.

Will there be bike share?

Treasure Island will be a perfect place for Ford GoBike expansion and we are coordinating with our public and private partners to enable timely implementation on Treasure Island. There are also 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 of the Bay and the nature on the Island.

When will the Bay Bridge bike-ped path open?

The Bay Bridge Bicycle and Pedestrian Path connecting Yerba Buena Island Oakland is open. For more information, visit the Bay Bridge Bicycle and Pedestrian Path website.

There are also plans for a bike path to connect Treasure Island to downtown San Francisco. Funding must first be secured in order to construct the path, which could cost hundreds of millions of dollars.



Has there been any outreach about the Treasure Island Transportation Plan?

The Treasure Island Mobility Management Agency has been engaging in ongoing community outreach in order to better understand the wants and needs of current and future Treasure Island residents, businesses, and visitors. Most recently, we conducted focus groups with residents, businesses, and others in fall 2017 to get feedback on plans for the Treasure Island Transportation Plan.

Here are some highlights on what we have heard, followed by discussion on how the Treasure Island Transportation Plan would address any questions and concerns.

  • Residents report that Muni Bus 25 is frequently overcrowded (especially in the evening peak from downtown San Francisco to Treasure Island).

Muni Bus 25 will start using larger buses in 2024 and increase frequency of service in 2025—eventually running every 3.5-minutes with larger buses to accommodate more capacity.

Planned ferry service between downtown San Francisco and Treasure Island will add capacity to further reduce crowding on the Muni Bus 25 line.

  • Muni Bus 25 is unreliable and frequently doesn’t adhere to schedule.

The Transbay Transit Center will have a direct throughway to the Bay Bridge, enabling Muni Bus 25 to avoid congestion in downtown San Francisco, providing more reliable service.

Planned ferry service between downtown San Francisco and Treasure Island will also provide a reliable option to get to and from the island.

  • There is no direct public transportation service to the East Bay.

AC Transit will serve Treasure Island with a direct connection to East Bay cities starting in 2021.

  • 95 percent of the participants indicated the two most expensive transportation costs were owning and maintaining their automobiles.

The Treasure Island Mobility Management Agency is addressing transportation affordability issue by increasing travel options and public transit availability. As more transportation options become available, it will be easier for families to shed their cars and save money in the process.
