Southern California Association of Governments

Southern California Association of Governments. It is the largest metropolitan planning organization in the United States, encompassing six counties and 191 cities across a vast region of Southern California. Established by an act of the California State Legislature in 1965, the organization is responsible for regional planning and coordination on critical issues including transportation, housing, economic development, and environmental sustainability. SCAG's planning area includes the heavily populated counties of Los Angeles, Orange, San Bernardino, Riverside, Ventura, and Imperial.

History

The organization was formally created in 1965 through the Joint Exercise of Powers Act following growing recognition of the need for coordinated regional planning in the rapidly growing Los Angeles metropolitan area. Its formation was influenced by earlier regional bodies like the Los Angeles County Regional Planning Commission and reflected national trends embodied in federal legislation such as the Federal-Aid Highway Act of 1962. Key early efforts focused on developing the region's first comprehensive transportation plan and addressing air quality challenges, which later dovetailed with the mandates of the Clean Air Act. Over decades, its role expanded significantly with federal laws including the Intermodal Surface Transportation Efficiency Act and the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users.

Organization and governance

The association is governed by a Regional Council composed of elected officials from its member cities and counties, with leadership including a President, such as Jan Harnik of Palm Desert, and a Vice President. Day-to-day operations are managed by an Executive Director, a position held by individuals like Kome Ajise, who oversees a professional staff at its headquarters in downtown Los Angeles. Policy development is supported by several standing committees, including the Transportation Committee and the Community, Economic, and Human Development Committee. The organizational structure also includes a General Assembly that convenes annually to set broad policy directions for the region.

Regional planning functions

As the designated metropolitan planning organization, its core mandate is to develop and maintain the long-range Regional Transportation Plan and Sustainable Communities Strategy, a requirement under California Senate Bill 375. It conducts continuous planning for the multimodal transportation network, coordinating with agencies like LA Metro, the California Department of Transportation, and the Federal Highway Administration. Additional planning responsibilities encompass regional housing needs assessment, air quality conformity analysis in coordination with the South Coast Air Quality Management District, and economic forecasting. It also plays a key role in hazard mitigation planning and supports local general plan consistency with regional goals.

Member jurisdictions

Membership includes all incorporated cities and the county governments within the six-county region, representing a population exceeding 19 million people. Key city members include Los Angeles, San Diego (within Imperial County), Long Beach, Anaheim, Riverside, and San Bernardino. The county members are the boards of supervisors from Los Angeles County, Orange County, San Bernardino County, Riverside County, Ventura County, and Imperial County. Each member jurisdiction has representation on the Regional Council, with voting power weighted by population.

Major initiatives and plans

Its landmark documents include the Connect SoCal Regional Transportation Plan and Sustainable Communities Strategy, which integrates land use and transportation planning to meet state greenhouse gas reduction targets. The organization also oversees the implementation of the Regional Housing Needs Assessment allocation process, distributing state-mandated housing targets to cities. Other significant programs include the Go Human safety campaign, the Regional Comprehensive Plan, and the Active Transportation Program. It has also launched initiatives focused on goods movement efficiency through the Alameda Corridor and Port of Los Angeles, and resilience planning for climate adaptation.

Funding and finance

Primary funding sources include federal grants from the United States Department of Transportation and the Federal Transit Administration, as well as state funds from the California Transportation Commission. Additional revenue comes from local subventions from member jurisdictions, grants for specific planning projects, and allocations from the California Department of Housing and Community Development. The association administers and allocates funding for regional transportation improvements and planning studies, and its financial plans are subject to approval by the Federal Highway Administration and the California State Legislature.
