Agency Type

The Southern California Association of Governments (SCAG) is the largest Council of Governments (COG) and Metropolitan Planning Organization (MPO) in the country.

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 (MPO) and under state law as a Regional Transportation Planning Agency (RTPA) and a Council of Governments (COG).

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 sustainable communities strategy and growth forecast components, regional transportation improvement programs, regional housing needs allocations and a portion of the South Coast Air Quality management plans.

In addition to the six counties and 191 cities that make up SCAG’s region, there are six County Transportation Commissions that hold the primary responsibility for programming and implementing transportation projects, programs and services in their respective counties.  There are also 14 “sub-regions” within the six counties that have varying degrees of responsibilities in the development of planning and programming transportation projects and developing policies.

Program Highlights
  • Local Profiles–Every two years, SCAG prepares Local Profile reports for the nearly 200 member jurisdictions in the region, providing updated data and analysis to support local planning and outreach efforts.  The demographic and socioeconomic data are also useful resources for the business community, academia and residents.  The most recent Local Profile reports were released at the 2013 Regional Conference & General Assembly in Palm Desert on May 2, 2013.
  • Toolbox Tuesday–Toolbox Tuesday is a quarterly event hosted by SCAG that offers workshops and panel series, with topics ranging from specific training on planning-related infrastructure to large-scale discussions on the California drought.  The workshops are free to attend and are geared to planning professionals and city and county staff and provides them with resources to enhance their job performance and is available for AICP credit.  Traditionally, Toolbox Tuesday has been 2-3 hours in the morning, but a recent workshop was an all-day event focusing on best practices and transportation and grant funding, which SCAG is looking to model future workshops after.
  • Transportation Modeling Services–SCAG maintains a complex modeling system that forecasts travel demand and air quality to support SCAG’s planning program. The information these models produce is also useful to member agencies, universities, and other public agencies. SCAG provides modeling data to support stakeholders’ planning programs and to assist in the development and maintenance of city and subregional models. SCAG supports subregional and city-level modeling programs by providing modeling setups, input data, training, and technical advice.
  • Data Services–Data Services provides up-to-date demographic and economic data to member jurisdictions, which can be used for local planning studies and policy initiatives.  SCAG makes available a Monthly Economic Report for the region along with a number of detailed datasets (job growth, unemployment, taxable sales,building permits, and various other socioeconomic variables), which are available for download in the Economic & Demographic Library.  Members can also request customized datasets for local analysis on an on-going basis.
