The RTP/SCS Development Process

About the RTP/SCS Development Process

Every four years the Southern California Association of Governments prepares a long-range Regional Transportation Plan (RTP) for the six-county region that includes Los Angeles, Orange, San Bernardino, Riverside, Ventura and Imperial counties. The RTP includes a Sustainable Communities Strategy (SCS) which outlines how the region can better integrate land use and transportation planning. The RTP/SCS details how the region will address its transportation and land use challenges in order to achieve its federal regional air quality emissions standards and state greenhouse gas reduction targets. Ultimately, the vision of the RTP/SCS is to improve the quality of life for the region’s residents by making the best transportation and land use choices for the future and supporting those choices with wise investments.
