East County Bus Operations and Maintenance Facility

Construction started in fall 2014 to expand and modernize the East County Bus Operations and Maintenance Facility located in the City of El Cajon – an important hub that employs 115 bus operators and 14 mechanics who provide bus services to more than 4 million riders each year.

The project consists of building a new compressed natural gas (CNG) fueling station to enable San Diego Metropolitan Transit System (MTS) to replace diesel buses with clean-burning CNG vehicles; demolishing outdated buildings and constructing new administrative offices, a bus maintenance building, and a bus wash facility; and reconfiguring bus and staff parking to maximize efficiency.

The CNG fueling station, a 34,500-square-foot maintenance building, and a 10,275-square-foot administrative building opened for service in October 2016 with the remainder of the project completed the fall of 2017.

The new LEED (Leadership in Energy and Environmental Design) Silver facility will be home to 120 CNG buses. The buses provide significant air quality benefits:

• A 53 percent reduction in NOx emissions
• An 85 percent decrease in particulate matter pollution
• 89 percent decrease in CO emissions

The East County Bus Operations and Maintenance Facility sits on 5.5 acres and is the base for providing bus services for urbanized areas along Interstate 8, as well as rural and unincorporated parts of the county.

The total project cost was $45 million, including environmental clearance, design, engineering, and construction. SANDAG, MTS, a Federal Transit Administration competitive grant, and state funds (Transit Development Act and State Transit Assistance Program) helped pay for the project.
