Federal-Aid Committees

Federal-Aid Committees (FAC) are an essential part of developing and implementing the Regional Transportation Plan for Southeast Michigan. There is an FAC for each of SEMCOG's seven counties as well as the City of Detroit. FACs are comprised of representatives of local units of government, transit agencies, and MDOT. FACs are charged with evaluating data and recommending projects that meet regional transportation goals while satisfying local needs. FACs meet to discuss and approve project recommendations, which are submitted to SEMCOG for inclusion in the 2045 RTP project list. Contact information for each FAC can be found on the Federal Aid Committees page.
