History

The Southern California Association of Governments was formed on October 28, 1965, with the purpose of conducting growth forecasts and regional planning. With each new federal transportation authorization and key state legislation, SCAG’s roles and responsibilities have increased and expanded beyond transportation planning. In recent years, SCAG has taken a leadership role in goods movement activities and its impact on the Southern California region. In 2008, the California State Legislature passed SB 375, which sets a framework and target dates to achieve Green House Gas reductions. This legislation impacts transportation planning, growth and development, housing, and land use decisions. It also expands the role of SCAG in setting regional targets.
