The Association of Monterey Bay Area Governments (AMBAG) is the federally designated Metropolitan Planning Organization (MPO) for the tri-county Monterey Bay Region. It is the lead agency responsible for developing and administering the transportation plans and programs that receive federal funds in Monterey, San Benito and Santa Cruz Counties. As the MPO, AMBAG act as a forum for cooperative decision making in the development of transportation plans, programs and recommendations. AMBAG also provides opportunities for citizens to participate in the discussion of specific transportation issues and projects, and encourages the public to get involved throughout the Metropolitan Transportation Planning process.
AMBAG works with Regional Transportation Planning Agencies (San Benito County Council of Governments, the Santa Cruz County Regional Transportation Commission and the Transportation Agency for Monterey County), Transit Providers (Monterey Salinas Transit and Santa Cruz METRO Transit District), the Monterey Bay Air Resources District (MBARD), state and federal governments, and organizations having interest in or responsibility for transportation planning and programming. AMBAG also coordinates transportation planning and programming activities with the three counties and eighteen local jurisdictions within the tri-county Monterey Bay Region.
