Southern California Association of Governments (SCAG)
Contact
Southern California Association of Governments (SCAG) is the largest MPO in California, covering six counties and 191 cities in the Southern California region. It is the transportation planning agency responsible for developing and implementing the long-range regional transportation plan, known as the Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS).
The 2016 RTP/SCS continues to emphasize the key land use and transportation strategies in the first SCS that support a more sustainable future for the SCAG region. SCAG anticipates new growth will occur within existing urban boundaries with higher density development instead of sprawling outward. The 2016 SCS continues on the course set by the 2012 SCS to direct transportation investments within existing urbanized areas to support a more compact urban form. It includes an extensive regional bus and bus rapid transit (BRT) system, improved commuter and light rail service, an expanded regional bicycle network, improved pedestrian infrastructure, dedicated highway lanes for carpool and express buses, and several transportation demand management programs that reduce the number of vehicle trips.
