MPO Policies & Procedures

The Tri-County Regional Planning Commission was designated by the Governor as the Metropolitan Planning Organization (MPO) in 1973, responsible for fulfilling all federally required transportation planning requirements in the Lansing-East Lansing Metropolitan area throughout Clinton, Eaton and Ingham counties in the state of Michigan. Federal funding for transportation projects throughout the three counties are channeled through Tri-County. Learn more about our role as the MPO for the tri-county region here.


Federally required processes and analyses that are specific to the Metropolitan Transportation Plan (MTP) and Transportation Improvement Program (TIP), such as Environmental Justice and Air Conformity, are included in their respective documents.


Additional agency-wide policies and publications, such as financial and operating procedures, may be viewed in the Projects & Documents Library.
