State Transportation Improvement Program
The State Transportation Improvement Program (STIP) is a five-year state funding program that is adopted by the California Transportation Commission (CTC) for transportation projects. The STIP is divided into two major funding categories: the Regional Transportation Improvement Program (RTIP) and the Interregional Transportation Improvement Program (ITIP). Seventy-five percent of the program is allocated to the RTIP, which is then provided to counties by formula to help deliver transportation capital projects that are consistent with the regional transportation plan. The remaining 25 percent is provided to the California Department of Transportation (Caltrans) through ITIP for transportation projects of interregional significance and intercity rail projects. OCTA is submitting a 2026 STIP proposal that if approved will provide Orange County with $151.742 million in funding for FY 2026-27 through FY 2030-31 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.
