Transportation Development Act Funds
The Transportation Development Act (TDA) is administered by Regional Transportation Planning Agencies (RTPA) such as the Sacramento Area Council of Governments (SACOG). It provides two major sources of public transportation funding in California.
- Local Transportation Fund (LTF), enacted in 1972
- State Transit Assistance (STA) fund, enacted in 1980
Explanations of these funds and annual apportionments for each jurisdiction are provided below and published annually.
Specifics on TDA statute can be found in the Transportation Development Act Statutes and California Code of Regulations published annually by Caltrans and can be accessed online. SACOG has also adopted specific guidelines for regional TDA implementation detailed in the TDA Guidelines. A detailed description of the law and the funds are described in the introduction of the Guidelines.

Unmet Transit Needs
Part of SACOG’s responsibility under TDA is to conduct an annual Unmet Transit Needs process to determine whether jurisdictions allowed to use the remaining TDA funds for streets and roads projects can do so and identify new transit needs in the region. Annual public hearings are held to collect public testimony on transit needs.

Triennial Performance Audit
The Transportation Development Act (TDA) requires SACOG to conduct a performance audit of transit operators who receive TDA funding every three years. The audits highlight key trends that may have an impact on an operator's ridership and financial performance. For more information, see the Performance and Oversight page.
