TFCA Regional Fund

Learn more about the TFCA Regional Fund and Air District Sponsored Programs and explore funding opportunities for clean air vehicles and trip reduction projects.

Vehicle emissions contribute to unhealthy levels of ozone, also known as "smog," and particulate matter.

In the Bay Area, tailpipe emissions from on-road motor vehicles account for more than 40 percent of the criteria air pollutants and about 36 percent of the green-house gases emitted. Significant emissions reductions from the on-road transportation sector are key to helping the Bay Area attain state and federal ambient air quality standards, and GHG emission reduction targets.

In 1991, the California State Legislature authorized the Air District to impose a $4 surcharge on cars and trucks registered within its jurisdiction to be used to provide grant funding to eligible projects that reduce on-road motor vehicle emissions. The Air District allocates these funds to its Transportation Fund for Clean Air Program, which in turn provides funding to qualifying trip-reduction and alternative fuel vehicle based projects, including plug-in electric vehicles.

Sixty percent of TFCA funds are awarded by the Air District to eligible programs and projects through a grant program known as the Regional Fund and through various Air District sponsored programs and projects including Spare the Air, and certain alternative fuel vehicle based and bicycle facility programs.

The remaining 40 percent of TFCA funds are passed through to the County Program Manager Fund and are awarded by the Congestion Management Agencies of the nine counties to TFCA-eligible projects located within those counties.

TFCA Regional Fund and Air District Sponsored Programs

TFCA Regional Fund and Air District Sponsored Program funding may be used to implement eligible projects that achieve reductions in criteria pollutant emissions from on-road mobile sources within the boundaries of the Air District’s jurisdiction.   Eligible project types include:

  • Trip reduction – the operation of commuter shuttle and ridesharing services, and pilot trip reduction projects (for public agencies only).
  • Clean air vehicles and infrastructure – the purchase or lease of new alternative fuel vehicles and alternative fuel infrastructure (open to all entities).
  • Bicycle facilities - the creation of new bicycle paths/lanes/routes, and deployment of new bike parking facilities, e.g., lockers and racks (for public agencies only).

Each year, the Air District’s Board of Directors approves an allocation of new TFCA funds for eligible project categories, and then adopts corresponding policies for the TFCA Regional Fund and Air District Sponsored programs that govern the use of the funds. Solicitations and Call for Projects are issued following the allocation of funds and the adoption of TFCA policies.

TFCA projects are evaluated on the basis of their effectiveness at reducing criteria pollutant emissions from on-road mobile sources, and undergo a fiscal audit following completion. Reports on project effectiveness and the audit results are reviewed annually by the Air District’s Board of Directors and made available to the public.

FYE 2018 TFCA Regional Fund Policies – Open for Public Comment

The Air District is currently seeking public comment on the draft TFCA Regional Fund Policies and Evaluation Criteria for Fiscal Year Ending (FYE) 2018.  Based on stakeholder input, a final draft of these Policies and Evaluation Criteria will be developed for consideration by the Air District’s Board of Directors in Spring of 2017.
