The 18 cities and county government are SANDAG, the San Diego Association of Governments. This public agency serves as the forum for regional decision-making. SANDAG builds consensus; makes strategic plans; obtains and allocates resources; plans, engineers, and builds public transportation, and provides information on a broad range of topics pertinent to the region's quality of life.
The San Diego County Regional Transportation Commission (Commission) is a blended component unit of SANDAG and therefore, is considered part of the SANDAG primary government. The SANDAG Board of Directors also serves as the Commission's Board of Directors. The Commission is responsible for the implementation and administration of transportation improvement programs funded by the San Diego countywide one-half percent sales tax. This tax became effective on April 1, 1988, as a result of the passage of Proposition A - The San Diego County Transportation Improvement Program, known of TransNet. The sales tax funds are used for highway, public transit, local street and road improvements, bicycle and pedestrian facilities, and administration.
