Potrero Yard Modernization Project

Help us design a new bus yard with housing on top that adds to the neighborhood! A modern Potrero Yard will help the SFMTA prepare for natural disasters like earthquakes and the effects of climate change, be more cost-effective and most importantly, help us keep more buses on the road, serving you.

Why Replace the Potrero Yard?

Every day, 102,000 riders rely on buses from the Potrero Yard to get them where they need to go. However, the current facility is more than 100 years old and presents challenges for our operation. The Potrero Yard was built in 1915 before the advent of modern seismic safety and maintenance standards. In many of the maintenance bays, the ceiling is too low to do roof repairs indoors or lift buses to repair them from below, slowing down work and making harder to keep buses in service.  Fewer buses in service mean longer waits and more crowding for riders.
As Muni expands service to keep up with our ridership, we need more space to park and maintain our growing fleet. Over the last several years, the SFMTA has increased service by 10% – the largest expansion since the 1970s.  By 2025, Muni will operate 200 more vehicles than the nearly 1,300 transit vehicles we operate today. We are replacing our fleet making it the nation’s cleanest and most modern. Our existing maintenance yards are too small for those new vehicles and too old to use new technologies like battery electric buses. That is why we are modernizing Potrero Yard so we can provide San Franciscans better transit service.

Decisions to be Made:

The SFMTA plans to work closely with partner agencies, the Planning Department, the Office of Economic and Workforce Development, and local elected officials on key decisions.

• Joint uses like housing or Production, Distribution, and Repair (PDR)
• Developer to construct the new facility
• Architectural features, urban design, and public art and facilities

Promise to the Public

The SFMTA is reaching out to the community to help shape many of the decisions that are needed to rebuild Potrero Yard.  The SFMTA will:

• Be transparent about the constraints of the project that will guide our decision making
• Work to understand and address stakeholder concerns and priorities.
• Balance stakeholder concerns and priorities while also meeting the project's core transit objectives.

Potrero Yard Neighborhood Working Group

The SFMTA is excited to work with the diverse communities near our facilities to modernize the 100-year-old Potrero Yard at 17th and Mariposa. The Potrero Yard Neighborhood Working Group has begun assembling community members to work with SFMTA staff to shape the public outreach, to weigh in on elements of the project design, such and help make the Potrero Yard and any potential for joint uses like housing on the site a good neighbor. The input and feedback will be important for ensuring that diverse viewpoints are considered and incorporated into the decision making for Potrero Yard.

Meetings of the Working Group will open to the public. You can find agendas, materials, and meeting minutes in the documents sidebar.
