The Office of Government & Community Affairs (GCA) is Columbia University’s primary liaison with federal, state, and local government, as well as with residents, community leaders, and civic organizations in our surrounding neighborhoods. The office has special responsibilities with regard to development of the University's Manhattanville Campus and the associated West Harlem Community Benefits Agreement.

GCA also manages Columbia Community Service (CCS), a program through which faculty and staff contribute to local non-profit organizations, the A'Lelia Bundles Community Scholars program, which gives local residents access to campus resources while they work on a project or skill that relates to or benefits their community, and the Community Advisory Council, which works with local residents and organizations to support and expand community partnerships.
