State Transportation Improvement Program (STIP)

The State Transportation Improvement Program (STIP) is funded through the State Highway Account and other sources for projects to increase the capacity of the transportation system. STIP projects may include projects on state highways, local roads, intercity rail, or public transit systems. The current 2002 STIP is a four-year program, which the California Transportation Commission (CTC) approved in April 2002.

Similar to the federal government, the amount of funds available for the STIP is dependent on the state budget. Therefore, funding levels may fluctuate from year to year. However, in developing the budget, the legislature, as well as the State Department of Transportation (Caltrans) and the State Department of Finance, consider future revenue and expenditure forecasts. Since the state fiscal year starts on July 1 and ends on June 30, the state budget is usually developed starting in early spring.

Regional Transportation Planning Agencies (RTPAs), such as SANBAG, are allocated 75 percent of STIP funding for regional transportation projects in their Regional Improvement Program (RIP). Caltrans is allocated 25 percent of STIP funding for interregional transportation projects in the Interregional Improvement Program (IIP).
