The Tri-County Regional Planning Commission was formed under the Regional Planning Act, PA 281 of 1945. It was established pursuant to resolutions adopted by the Boards of Supervisors of Clinton, Eaton, and Ingham counties on July 18, 1956. Membership was expanded to include the City of Lansing in 1974. Tri-County serves 75 jurisdictions within the three-county region.
