Funding
Transportation Fund for Clean Air 40% Fund Program
The Bay Area Air District’s Transportation Fund for Clean Air (TFCA) is collected from a $4 fee on all vehicle registrations within the Air District’s boundaries. The initial 60% of these funds are applied to the TFCA Regional Program, which is administered by the Bay Area Air District. The remaining 40% is distributed to each Bay Area County Congestion Management Agency (CMA) through the TFCA 40% Fund Program.
Solano Transportation Authority, as the CMA for Solano, annually administers the TFCA 40% Fund Program.
Solano Transportation Authority (STA) invites public agencies within the Bay Area Air District basin: City of Benicia, Fairfield, Suisun City, Vallejo, and the southwestern portion of the unincorporated County of Solano to submit grant applications for the Transportation Fund for Clean Air (TFCA) 40% Fund Program Call for Projects. This is part of a coordinated call for projects for One Bay Area Grant Cycle 4 (OBAG 4), CARE, and TDA-3 discretionary funds.
There is $1 million in funding available for active transportation projects, such as bicycle and pedestrian projects, smart growth/traffic calming, and other clean air projects in alignment with the TFCA 40% Fund Program Guidelines. Active transportation projects will be prioritized for funding.
As part of this Call for Projects, STA staff will be developing a funding plan for up to 4 years as part of the Coordinated Call for Projects with the OBAG 4, CARE, and TDA-3 STA discretionary funds.
