Building Progress Program


As we move forward with the goals of creating a greener, more efficient, and modern transportation system, we want to emphasize the importance of strengthening our aging infrastructure. The SFMTA has identified critical updates that are needed for 100-year-old bus yards, guided by the Building Progress Program. Improving bus yards and making them greener can make Muni service more reliable and is critical for meeting the city’s ambitious climate change goals. Our infrastructure is the backbone of San Francisco's transportation system.

Project Introduction

Over the last several years, the San Francisco Municipal Transportation Agency (SFMTA) has made historic investments guided by the SFMTA Strategic Plan and its underlying goals. Investments that support reliable Muni service include expanding the Muni bus and light rail fleet and opening the Islais Creek Maintenance and Operations Bus Facility in the summer of 2018. Additionally, the SFMTA is working to transition to an all electric bus fleet by 2040. These investments are helping to move more residents, employees, and visitors than ever before and are critical in meeting the city’s ambitious climate change goals.  

Yet, the SFMTA facilities that support these investments need to be maintained, updated, and modernized. Our infrastructure is the backbone of San Francisco's transportation system. Neglecting the current condition and needed upgrades to these facilities will prevent the SFMTA from maintaining our street infrastructure and protecting, storing, and maintaining our diverse transit fleet. 

The Building Progress Program is a $2.3 billion multi-year effort to repair, renovate, and modernize the SFMTA’s aging facilities to keep the City moving and transition to a battery-electric bus fleet.

The San Francisco Municipal Transportation Agency (SFMTA) was established in 1999, by voter mandate, and combined the Taxi Commission, the Department of Parking and Traffic, and the Municipal Railway (Muni). As a result, the SFMTA oversees approximately 702,000 daily Muni boardings, 7,200 street intersections, 431 miles of bike paths and much more. By the year 2049, the city is projected to grow to nearly 1,000,000 residents. Therefore moving San Francisco’s residents and visitors is not only important today, but will continue to be essential in the future.

The SFMTA has 20 facilities, which are needed to support Muni transit service, paratransit service, street infrastructure, sign and paint shops, and other critical functions that keep San Francisco moving.

The SFMTA's Real Estate and Facilities Vision for the 21st Century was developed in 2013, to provide recommendations on how to improve operational efficiencies, determine sustainable initiatives, identify funding sources, advance the Agency’s goals for transit-oriented development and joint development, and outline an implementation roadmap. 

Four years later, the 2017 SFMTA Facilities Framework helped identify deficiencies, associated costs and prioritized improvements for 18 SFMTA facilities. The Building Progress Program is carrying out the framework’s recommendations by implementing its five elements:

  1. Plan for the future of SFMTA buildings and yards.
  2. Engage SFMTA staff, communities surrounding SFMTA facilities and additional stakeholders.
  3. Fund and manage the cash flow of the Building Progress Program.
  4. Fix and repair buildings and yards based on former facility study recommendations.
  5. Deliver on the programs and projects recommended in the 2017 SFMTA Facilities Framework through capital design and construction.

 Among the first major sites for improvement in the Building Progress Program are the following:

  • The Potrero Yard Modernization Project will replace the obsolete two-story maintenance building and bus yard located at Bryant and Mariposa streets with a modern, three-story, efficient bus maintenance and storage garage, equipped to serve the SFMTA’s growing fleet as it transitions to electric vehicles. Construction is expected to begin in 2024.

  • The Presidio Yard Modernization Project will replace the obsolete two-story maintenance building and bus yard located at Geary Boulevard and Presidio Avenue.
