Transportation Development Act (TDA)

Transportation Development Act (TDA)Top of Page

The Transportation Development Act (TDA) is one of the major funding sources for public transit in California. The TDA provides two funding sources:
  • the Local Transportation Fund (LTF) and
  • the State Transit Assistance (STA) fund
The LTF is derived from ¼ cent of the 7¼% general statewide sales tax. This ¼ cent of the sales tax is returned to every county in the state from where the tax was collected.
The STA is derived from sales tax on gasoline and diesel fuel. Fifty percent of STA funds are allocated according to population. The other fifty percent is allocated according to the ratio of the total public transit revenues that were generated in each area during the prior fiscal year.

TDA Workbook
BCAG has prepared a TDA "Workbook" as a guide to assist in the development of the TDA Claims.  The following is strickly a guide to provide assistance in the general understanding of the TDA Statutes.  This workbook was created in November 2003.  BCAG intends to update the workbook to reflect current practices, Caltrans TDA Guidebook and recommendations from the audit process. This guidebook was developed prior to the consolidation of the transit systems which created Butte Regional Transit in July 2005.
Please direct any comments or questions to Mr. Ivan Garcia, BCAG Programming Manager at or Ms. Julie Quinn, BCAG Chief Fiscal Officer at or by phone directly at 530-809-4616.  Questions about a local jurisdiction's priorities should be directed to the local jurisdiction's finance office.
