MTS operates bus services out of five “divisions” where buses are parked, fueled or charged, cleaned, and maintained while not in service. These divisions are located throughout the MTS service area to optimize proximity to routes and services. This minimizes unnecessary travel, cost, and fuel, and enhances our ability to respond to operational needs in a timely manner. Each division has space for 150-250 buses, and can be up to 12 acres with as many as 600 employees.

With over 800 buses in the MTS bus fleet, the current divisions are nearing maximum capacity. Plans for growing the transit system over the next 30 years will require room for more buses. In addition, the transition from natural gas to zero-emission electric buses over the next 19 years will require new charging infrastructure at our divisions that will reduce available space for buses.

This project will provide MTS a sixth bus division in the middle of its future operational service footprint. MTS is seeking a parcel in an area already zoned for commercial or industrial use to minimize impacts to nearby properties. It will be designed from the ground-up to primarily park, charge, and service zero-emission buses. In addition to being a well maintained and LEED-certified facility, the project will provide up to 600 new, high-quality jobs for the local community.

Estimated Schedule

Schedule shown is the best estimate at the time of publication and is subject to change as the project progresses.

  • Community Engagement: Beginning Summer 2021 and throughout project
  • Site Selection & Environmental: 2021-2022
  • Design: 2022-2024
  • Construction: 2025-2027
  • Completion/Opening: 2027

Project Status (updated March 2022)

The San Diego Association of Governments (SANDAG) is the lead agency on the Clean Transit Advancement Campus project and is currently conducting analyses of seven sites for the purposes of environmental impacts. MTS selected a preferred site in late 2021 following initial public engagement and a technical review of site feasibility. A consultant is working on the technical studies, which are expected to take through mid-2022. In March 2022, MTS approved a contract for a consultant to sketch concept site layouts for the preferred site, which will assist SANDAG in evaluating potential environmental impacts for the technical studies.

Location (updated March 2022)

MTS is evaluating seven potential sites along the Interstate 805 corridor between North Park and Lincoln Park for proximity to future growth in service. A preferred site on Federal Blvd. was selected in late 2021, but the environmental analysis will continue to evaluate all seven sites. The selection of a preferred site launched the environmental analysis phase.


$150-$200 million. Project will be initially funded through MTS’ annual Capital Improvement Program, but MTS will actively seek grants and federal funding participation as the project progresses.

Public Outreach Events

  • Fall 2021

    • MTS hosted two hybrid in-person and virtual public outreach sessions to share project details and provide a forum for a community discussion.

      Both events took place at the Valencia Park/Malcolm X Library, 5148 Market Street, San Diego, CA 92114, and over Zoom.

      Presentation Materials

  • Summer 2022

    • MTS hosted two virtual public outreach sessions and one open house to share project updates about the potential for a new all-electric bus operations facility in the Webster or Mt. Hope communities. The open house session took place at the Euclid Avenue Transit Center.
