The State Transportation Improvement Program (STIP) is a major source of funding for transportation improvements throughout the State of California. The STIP is divided into two major funding categories: the Regional Improvement Program (RIP) and the Interregional Improvement Program (IIP). Seventy-five percent of the STIP is directed to the RIP, which is then sub-allocated to counties by formula. The remaining 25 percent is programmed to the IIP, which is then allocated to the California Department of Transportation (Caltrans) for projects of interregional significance. The OCTA is submitting a 2024 STIP proposal that if approved will provide Orange County with $222.326 million in funding for FY 2024-25 through FY 2028-29 for the five year STIP cycle.

The Capital Programming Policies were approved by the OCTA Board of Directors on December 13, 2021 and can be found here.
