Transportation Development Act

The Transportation Development Act of 1971 (TDA), also known as SB 325, is administered by the California Department of Transportation (Caltrans) through the county’s designated regional transportation planning agency (RTPA). The Placer County Transportation Planning Agency (PCTPA) is the RTPA for Placer County. The Act provides two major sources for funding of public transportation in California. The first, the county Local Transportation Fund (LTF), was established in 1972, while the State Transit Assistance (STA) fund was implemented in 1980. When Senate Bill 1 (SB 1) passed in 2017, a new program called the State of Good Repair (SGR) was added as a source of funding for maintaining transit systems across the state. The intent of the legislation is to provide a stable source of funding to meet the area’s transit needs.
