Muni Metro East Bus Yard and 1399 Marin Street Facilities

SFMTA.com/BusYardEast
Project Introduction

In 2017, the San Francisco Municipal Transportation Agency (SFMTA) launched the Building Progress Program, a $1.2 billion multi-year effort, to repair, renovate, and modernize the SFMTA’s aging facilities to keep the City moving. (Potrero Yard, located at Bryant and Mariposa streets, is the first Building Progress Program capital rebuild project. Construction for Potrero Yard is expected to begin in 2024.)

Two SFMTA facilities in southeast San Francisco will soon play an important part in these upcoming rebuild projects. As a bus yard is taken offline for construction, operations will be relocated to a temporary bus yard at Muni Metro East (MME) and heavy maintenance functions will be relocated to 1399 Marin Street.

After rebuilding bus yards across the City, the SFMTA will consider using this yard to expand MME rail operations.

For more information, read the detailed report of our MME Environmental Review Determination.

Project Proposal 

As part of the Building Progress Program, operations and maintenance activities at Muni Metro East and 1399 Marin will expand to continue Muni operations and maintenance during the rebuild of other bus yards.

Bus Yard at MME

Four acres of vacant land adjacent to the current MME site will be used as a bus operations yard to support the following activities: 

  • Bus operations, operator check-in trailers, lockers, restrooms, and break space.
  • Bus washing served by below-grade rainwater cistern, fare pull, and interior bus cleaning.
  • Overhead trolley charging (in yard only) and parking for approximately 105 trolley buses.
  • Landscaped bioswale with native plants for storm water capture and to mitigate sea-level events.
  • 24-hour security, 10’ security fence, three pedestrian gates, and one rolling bus gate
  • Accessing the improved street on Maryland Street from Cesar Chavez.
