OKI is the Metropolitan Planning Organization (MPO) for an eight-county, tri-state region which includes Butler, Clermont, Hamilton and Warren counties in Ohio; Boone, Campbell and Kenton counties in Kentucky; and Dearborn County in Indiana. An MPO is a federally mandated and funded transportation policy-making organization that is made up of representatives from local government and governmental transportation authorities. The Federal-Aid Highway Act of 1962 required the formation of an MPO for any urbanized area with a population greater than 50,000. MPO’s were created to ensure that existing and future expenditures of governmental funds for transportation projects and programs are based upon a continuing, cooperative, and comprehensive (3-C) planning process that results in plans and programs that consider all transportation modes and supports regional community development and social goals.
