This line shapefile represents capital improvement projects on California's state highways that are part of the State Transportation Improvement Project (STIP). The STIP is a resource management document to assist state and local entities to plan and implement transportation improvements and to utilize available resources in a cost-effective manner. The STIP is a listing of all capital improvement projects that are expected to receive an allocation of state transportation funds from the California Transportation Commission (CTC) during the following five years. The STIP consists of two broad programs, the regional program funded from 75% of new STIP funding and the interregional program funded from 25% of new STIP funding. The 75% regional program is further subdivided by formula into county shares. County shares are generally available for projects nominated by a Regional Transportation Planning Agency (RTPA) in their RTIPS. Amendments to the STIP are made by the entity that submitted the project and require a 30-day public notice. The list of capital improvements projects was extracted from The CTIPS (California Transportation Improvement Program System) database. This layer is part of a collection of GIS data created by the California Department of Transportation (Caltrans).This feature class represents all segments of capital improvement projects on the State Highway System that are currently programmed in the State Transportation Improvement Program (STIP).
