About us
Founded in 1965, SCAG is a joint powers authority under California state law, established as an association of local governments and agencies that voluntarily convene as a forum to address regional issues. Under federal law, SCAG is designated as a metropolitan planning organization. Under state law, SCAG is designated as a regional transportation planning agency and a council of governments.
The SCAG region encompasses six counties (Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura) and 191 cities in an area covering more than 38,000 square miles. The agency develops long-range regional transportation plans, including a sustainable communities strategy and a growth forecast, regional transportation improvement programs, regional housing needs allocations, and a portion of the South Coast Air Quality Management Plan. SCAG’s 86-member governing board, the Regional Council, conducts the affairs of SCAG; implements the General Assembly’s policy decisions; acts upon policy recommendations from SCAG policy committees and external agencies; appoints committees to study specific problems and programs; and amends, decreases or increases the proposed budget to be reported to the General Assembly.
