regional planning + local relevance The Atlanta Regional Commission (ARC) serves as a catalyst for regional progress by focusing leadership, attention and planning resources on key regional issues. ARC is the regional planning and intergovernmental coordination agency for the 10-county metro Atlanta area including Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Fulton, Gwinnett, Henry and Rockdale counties, as well as the City of Atlanta. For 60 years, ARC and its predecessor agencies have helped to focus the region's leadership, attention and resources on key issues of regional consequence. ARC is dedicated to unifying the region's collective resources to prepare the metropolitan area for a prosperous future. It does so through professional planning initiatives, the provision of objective information and the involvement of the community in collaborative partnerships.
