Member Governments

The Commission is a regional partnership serving Peoria, Tazewell, and Woodford counties by providing a forum for cooperation, planning, and coordination on issues that affect the region as a whole. In addition, the Commission also serves as the federally designated Metropolitan Planning Organization (MPO) for the Peoria–Pekin Urbanized Area. In this role, the Commission represents the urbanized portion of the region for transportation planning and federal funding purposes.


Regional Member Counties


The Commission was created by and continues to serve the following counties:

  • Peoria County
  • Tazewell County
  • Woodford County

These counties jointly established the Commission under Illinois law to support coordinated regional planning and to address shared regional planning needs.


MPO Representation


As the MPO, TCRPC is responsible for regional transportation planning within the federally defined Peoria-Pekin Urbanized Area and the surrounding 20-Year Planning Area. Through its MPO role, TCRPC represents:

  • Municipalities located within the urbanized area
  • Counties that include urbanized and soon-to-be-urbanized areas
  • Regional transit providers

This ensures that transportation decisions reflect regional travel patterns, not just individual jurisdiction boundaries.


Commission Composition


The Tri-County Regional Planning Commission is governed by a 21-member Full Commission that serves as the policy and decision-making body for both the regional planning commission and the MPO. Commission membership includes:

  • Representatives appointed by each member county
  • Elected officials from municipalities
  • Representative from the Greater Peoria Mass Transit District (GPMTD)
  • A representative from the Illinois Department of Transportation (IDOT)

Appointments are structured to ensure broad geographic representation and compliance with federal metropolitan planning requirements. Below is a list of the jurisdictions and organizations that make up the 21-members of the Full Commission:


Role of Member Governments


Member governments participate in TCRPC by:

  • Appointing representatives to the Full Commission and committees
  • Participating in regional planning discussions and decision-making
  • Coordinating local priorities with regional plans and programs
  • Providing local financial support or match for planning programs
  • Collaborating on studies, plans, and initiatives

Through this participation, member governmentsl help shape regional transportation investments, community planning efforts, environmental strategies, and data initiatives.


Regional Collaboration Beyond Tri-County


While TCRPC’s core membership includes Peoria, Tazewell, and Woodford counties, the Commission also collaborates with neighboring counties and regional partners on initiatives such as transportation coordination, human services planning, environmental planning, and GIS & Data services when regional impacts extend beyond county boundaries.
