State Transportation Improvement Program (STIP)
The STIP is a multi-year capital improvement program of transportation projects on and off the State Highway System, funded with revenues from the Transportation Investment Fund and other funding sources. STIP programming generally occurs every two years. The programming cycle begins with the release of a proposed fund estimate in July of odd-numbered years, followed by California Transportation Commission (CTC) adoption of the fund estimate in August (odd years). The fund estimate serves to identify the amount of new funds available for the programming of transportation projects. Once the fund estimate is adopted, Caltrans and the regional planning agencies prepare transportation improvement plans for submittal by December 15th (odd years). Caltrans prepare the Interregional Transportation Improvement Plan (ITIP) and regional agencies prepare Regional Transportation Improvement Plans (RTIPs). Public hearings are held in January (even years) in both northern and southern California. The STIP is adopted by the CTC by April (even years). This process, as well as the STIP development and resources are available on the Financial Programming website.
Local agencies should work through their Regional Transportation Planning Agency (RTPA), County Transportation Commission, or Metropolitan Planning Organization (MPO), as appropriate, to nominate projects for inclusion in the STIP.
Once projects are programmed, agencies may begin the project implementation process. It is important to note that there are timely use of funds rules associated with STIP projects that are established by statute and outlined in both the STIP Guidelines adopted by the CTC and Chapter 25 of the Local Assistance Program Guidelines. This website is designed to provide local agencies and the general public with information regarding STIP guidelines and procedures. Several links to other Caltrans websites are provided.
This chapter outlines policies and procedures related to STIP projects. It contains website references to relevant information sources as well as exhibits and forms necessary for use by agencies implementing STIP projects. Chapter 25 supersedes Chapter 23 of the Local Assistance Program Guidelines - Local Agency State Transportation Improvement Program Projects.
Timely Use of Funds (Time Extension Requests)
The request for extension is initiated by the implementing agency and prepared on their letterhead as a letter addressed to the District Local Assistance Engineer (DLAE). Requests must be submitted to the District DLAE and the District Local Assistance ATP Coordinator using the LAPG 25-A Allocation/Time Extension Form.
After reviewing the request for extension, the DLAE will sign off and forward the request to Headquarters (Division of Local Assistance) to firstname.lastname@example.org
