Marin County Transit District

Marin County Transit District, operating as Marin Transit, is a U.S. local government transit authority that receives federal grant funding from the Department of Transportation Federal Transit Administration to operate paratransit and fixed-route transit services, maintain vehicle fleets, and fund transit infrastructure projects in Marin County, California. Marin Transit acts as a prime recipient on all federal grant awards; the organization does not hold federal contracts or serve as a subcontractor on contract work.

Marin Transit's federal funding footprint centers on transit operations and capital investment. The organization has received $148.8 million in combined obligated dollars across 43 awards since 1999, with 95% awarded as prime grants. The Federal Transit Administration dominates the customer base, funding 35 awards (81% of total awards) under the Federal Transit Formula Grants program (CFDA 20.507) and the Enhanced Mobility of Seniors and Individuals with Disabilities program (CFDA 20.513). Representative awards include a $15.981 million formula grant awarded August 18, 2026, to fund approximately 12 months of paratransit operations assistance through October 31, 2026, and purchase of 27 replacement vehicles (ultimate completion October 31, 2029); a $10.718 million formula grant awarded December 11, 2025, supporting 3.5 months of paratransit operations and purchase of nine replacement vehicles plus mid-life battery refurbishment for twenty vehicles (completion through December 31, 2027); and a $1.358 million formula grant awarded March 4, 2025, under CFDA 20.513 for mobility services including accessible van operations and mobility management (completion September 30, 2027). The Department of the Interior National Park Service also funds Marin Transit: a cooperative agreement awarded September 8, 2023, under CFDA 15.954 to operate the Muir Woods Shuttle Program managing visitor access during peak seasons (ultimate completion September 7, 2028). Marin Transit also received a $1.251 million formula grant in March 2024 for preliminary design and environmental clearance of a part-time transit lane on Highway 101, with the Transportation Authority of Marin identified as a subrecipient on project initiation activities.

Activity has been episodic: four awards in 2022, three in 2023, five in 2024, three in 2025, and one in 2026 year to date. Eight awards carry ultimate completion dates within the next twenty-four months, representing potential recompete exposure. Marin Transit has issued two sub-awards to other recipients as of the source data (April 16, 2025, and December 20, 2022), both for operating assistance. The organization does not compete for federal contracts and maintains no presence on contract vehicles or schedules; its federal footprint is exclusively grant-funded transit operations and capital projects serving Marin County residents, seniors, persons with disabilities, and park visitors.
