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 approximately 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 17 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.
Schedule shown is the best estimate at the time of publication and is subject to change as the project progresses.

Project Status (updated October 21, 2022)
MTS and the San Diego Association of Governments (SANDAG) are working collaboratively on the development of the CTAC, which is currently working towards environmental clearances. For the California Environmental Quality Act (CEQA), the MTS Board of Directors approved and adopted a Final Mitigated Negative Declaration on October 20, 2022.
In March 2022, MTS approved a contract for a consultant to sketch concept site layouts for a site on Federal Blvd. The MTS Board of Directors approved this location as the final project site on October 20, 2022. Project design will commence as the project advances through the National Environmental Protection Act (NEPA) clearance.

Location (updated October 21, 2022)
MTS evaluated seven existing industrial areas along the Interstate 805 corridor between North Park and Lincoln Park for proximity to future growth in service. Seven sites, located in the Ridgeview and Mount Hope communities, were identified as potential sites for evaluation. A site on Federal Blvd. in the Ridgeview community of San Diego was approved by the MTS Board of Directors on October 20, 2022. This site is identified as “Site 7” in project documents.
The 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. Initial estimates of up to $200-$350 million will be updated as a site is finalized and property acquisition and design work get underway.
Public Outreach Events
MTS hosted and participated in a dozen engagement events and presentations through 2021 and 2022. Feedback from community members and interested parties helped to inform SANDAG and MTS on project decisions through the CEQA phase.
