City/County Association of Governments of San Mateo County (C/CAG)
Agency Type

City/County Association of Governments of San Mateo County (C/CAG) provides a unique forum for all 20 municipalities and the county to work together to find cost-effective solutions for transportation, stormwater runoff, land use near airports, and climate protection.

C/CAG administers the state-mandated Congestion Management Program and prepares the Countywide Transportation Plan, which establishes a long-range transportation vision for the county and informs the Regional Transportation Plan and Sustainable Communities Strategy prepared by the Metropolitan Transportation Commission (MTC).  C/CAG also partners with local jurisdictions and other transportation agencies to develop transportation plans and studies for areas and projects with countywide and regional significance.

C/CAG’s member agencies are subject to regulatory mandates to reduce the amount of pollution carried by stormwater runoff to local creeks, San Francisco Bay, and the ocean. C/CAG established its Countywide Water Pollution Prevention Program to cost-effectively support these efforts by providing technical assistance to member agencies implementing local pollution prevention programs, and implementing countywide compliance activities or collaborating regionally with other Bay Area stormwater programs, when appropriate.

C/CAG acts also serves as the the Airport Land Use Commission for San Mateo County. The Commission has three primary responsibilities: to coordinate airport land use compatibility planning efforts at the state, regional and local levels; to prepare and adopt an Airport Land Use Compatibility Plan (ALUCP) for each public-use airport in its jurisdiction; and, to review plans, regulations and other actions of local agencies and airport operators.

C/CAG also provides support to the San Mateo County Subregion in performing the regional housing needs allocation (RHNA) in San Mateo County.  C/CAG, in partnership with San Mateo County Department of Housing, provides funding for the 21 Elements project to assist member jurisdictions with housing policy development and certification of Housing Elements.
