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.


The Tri-County Regional Planning Commission's bylaws, last amended in December of 2018, codify the structure, jurisdiction, roles, duties, and membership in the agency's Board of Commissioners. View Here

Agreements & Memoranda of Understanding

Tri-County maintains a variety of agreements with public transit providers in the region and the Michigan Department of Transportation to define agency responsibilities and ensure a continuing, cooperative and comprehensive (3-C) transportation planning process.

Public Participation Plan

Tri-County's Public Participation Plan (PPP) describes the ways in which the agency will engage the public when developing the PPP, the Transportation Improvement Program (TIP), and the Metropolitan Transportation Plan (MTP), among other transportation planning documents and programs. The PPP defines specific public participation opportunities - including milestones, procedures, and comment periods - for each of these documents. It deploys a variety of tools and techniques, from traditional print and in-person methods to visualization mediums and virtual strategies - to solicit feedback from and engage members of the public in the region. Below is the current PPP, last adopted in April 2017. View Here

Stakeholder Engagement Process (Consultation)

Tri-County's Stakeholder Engagement Process, which serves as the MPO Consultation Process, works to:

  • Minimize conflicts between transportation plans and projects with other agencies’ plans, projects, programs, or policies
  • Gather and consider input from stakeholder groups that may be impacted by transportation priorities and specific infrastructure and mobility projects
  • Mitigate negative impacts to sensitive environmental, cultural, economic, and other resources
  • Meet federal requirements to consult and coordinate with agencies and officials responsible for other planning activities that are affected by transportation
Tri-County invites a variety of public, private, and nonprofit organizations representing economic development and the business community, environmental protection and stewardship, community interests, the transportation sector, and local, state, and federal government to participate in this process. Below is the current process, last adopted in July 2020. View Here

Title VI Non-Discrimination Plan

Tri-County maintains a Title VI Non-Discrimination Plan to assure that services, programs, and activities are offered, conducted, and administered fairly without regard to race, color, national origin, sex, age, or disability of participants or beneficiaries. This plan establishes procedures to prevent discrimination in Tri-County's programs and process potential complaints by persons who believe they have been subjected to illegal discrimination under Title VI of the Civil Rights Act of 1964 and related regulations and directives. Below is the current Title VI Plan, last adopted in February 2021. View Here

Limited English Proficiency (LEP) Plan

Tri-County maintains a Limited English Proficiency (LEP) Plan to ensure accessibility to programs and services to persons who are not proficient in the English language. Executive Order 13166: Improving Access to Service for Persons with Limited English Proficiency states that individuals who do not speak English well and who have a limited ability to read, write and speak, or understand English are entitled to language assistance under Title VI of the Civil Rights Act of 1964. The plan identifies LEP persons who need language assistance, ways in which language assistance will be provided, staff training, guidance for providing notice to LEP persons, and the recommended method of evaluating accessibility to available transportation services - the Four-Factor Analysis identified by the USDOT. Below is the current LEP Plan, last adopted in February 2021. View Here

Regional & Unified Planning Work Programs

As the region’s MPO, Tri-County develops a Unified Planning Work Program (UPWP) in cooperation with the state and public transportation operators that identifies urban area transportation planning activities (including the responsible agency, schedule of work, resulting products, and proposed funding sources) for the upcoming fiscal year. Tri-County also develops a Regional Transportation Planning Work Program (RWP), which is the rural equivalent of the UPWP. The RWP outlines transportation planning activities to be completed in the rural areas of the region that are outside the designated urban area. View the most current UPWP and RWP here.


Every four years, the Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) complete a review of the transportation planning process in the Lansing-East Lansing metropolitan area to determine if the planning process conducted by the MPO - and local road agencies, State, and transit operators - meets the federal transportation planning requirements, which are prerequisites to the advancement of federal transportation projects in urbanized areas. Below is the last federal certification review report, completed in June 2017. View Here Tri-County also self-certifies that projects selected through the transportation planning process conform with all applicable federal laws and regulations, and confirms our commitment to comply with applicable federal transportation planning requirements - including prohibiting discrimination and following equal opportunity procedures .

MPO Planning Area Boundary

Federal rules require the designation of MPOs in urbanized areas of 50,000 or more in population as a condition for spending federal highway and transit funds. The Planning Area Boundary is the area within which the federal metropolitan transportation planning and programming requirements apply. View Here
