Vermont Regional Planning Commissions: Districts and Functions

Vermont operates 11 Regional Planning Commissions (RPCs) that divide the state into distinct geographic planning districts, each functioning as an intergovernmental body serving the municipalities within its boundaries. These commissions operate under authority granted by 24 V.S.A. Chapter 117, Vermont's Municipal and Regional Planning and Development Act. RPCs occupy a critical middle tier between state agencies and local governments, coordinating land use, transportation, housing, hazard mitigation, and economic development planning across Vermont's 14 counties and 251 municipalities. Understanding the district structure and functional scope of RPCs is essential for professionals engaged in permitting, infrastructure planning, Act 250 proceedings, or regional policy coordination.

Definition and scope

A Regional Planning Commission is a voluntary association of municipalities authorized under Vermont statute to carry out regional planning functions. Membership is not mandatory, but in practice the overwhelming majority of Vermont municipalities participate in their respective RPC. Each commission is governed by a board of commissioners appointed by member municipalities — typically one commissioner per member town or city, with appointment procedures set by individual municipal charters or selectboard votes.

The 11 RPCs and their general coverage areas are:

  1. Addison County Regional Planning Commission — Addison County
  2. Bennington County Regional Planning Commission — Bennington County
  3. Central Vermont Regional Planning Commission — Washington County and portions of adjacent counties
  4. Chittenden County Regional Planning Commission — Chittenden County, Vermont's most populous county
  5. Lamoille County Planning Commission — Lamoille County
  6. Northeastern Vermont Development Association — Caledonia, Essex, and Orleans counties
  7. Northwest Regional Planning Commission — Franklin County and Grand Isle County
  8. Orange County Regional Planning Commission — Orange County
  9. Rutland Regional Planning Commission — Rutland County
  10. Southern Windsor County Regional Planning Commission — southern Windsor County
  11. Windham Regional Commission — Windham County and portions of Windsor County

RPC district boundaries do not align perfectly with county lines in all cases. Windham Regional Commission and Southern Windsor County Regional Planning Commission both operate within Windsor County, creating a split that distinguishes Vermont's RPC geography from its county map.

Scope boundary: This page addresses Vermont's 11 state-authorized RPCs only. Federal regional planning bodies, interstate compacts (such as the Connecticut River Joint Commissions), and intra-municipal planning departments fall outside this scope. RPCs do not exercise zoning authority — that power remains with individual municipalities under Vermont's land use framework. State-level planning functions housed within the Vermont Agency of Commerce are also not covered here.

How it works

RPCs receive funding through a combination of municipal assessments, state grants administered through the Vermont Department of Housing and Community Development (DHCD), and federal pass-through funds from agencies including the Federal Highway Administration and the Economic Development Administration. The DHCD allocates a base planning grant to each commission annually, with amounts tied to statutory formula factors including population and geographic area.

Core statutory functions assigned to RPCs under 24 V.S.A. §4345a include:

Common scenarios

Three operational scenarios illustrate how RPCs function in practice:

Municipal plan update: A town such as Middlebury revising its municipal plan submits the draft to the Addison County Regional Planning Commission for a mandatory compatibility review. The RPC issues a written finding addressing whether the plan is consistent with the regional plan. A finding of inconsistency does not block municipal adoption but can affect DHCD approval and associated grant eligibility.

Act 250 proceeding: A developer proposing a commercial project exceeding applicable acreage thresholds near St. Johnsbury triggers Act 250 review before District 7 Environmental Commission. The Northeastern Vermont Development Association holds automatic party status and may submit technical comments or appear at hearings addressing criteria including traffic, water supply, and conformance with regional plans.

Regional transportation project: A corridor study affecting Morristown and adjacent towns is coordinated through the Lamoille County Planning Commission, which aggregates local input, interfaces with the Vermont Agency of Transportation, and ensures project priorities are reflected in the Statewide Transportation Improvement Program.

Decision boundaries

RPCs hold advisory and coordination authority — not regulatory or enforcement authority. This distinction separates them from bodies such as the Vermont Natural Resources Board or Vermont Public Utility Commission, which issue binding decisions.

Authority Type RPC Municipal Zoning Board District Environmental Commission
Binding permit decisions No Yes (local) Yes (Act 250)
Regional plan adoption Yes No No
Act 250 party status Yes (statutory) No Adjudicates
MPO designation (federal) Eligible No No

A municipality that disagrees with an RPC compatibility finding retains full authority to adopt its municipal plan regardless. The finding triggers procedural consequences (DHCD review, grant eligibility) but does not constitute a veto. This framework is consistent with Vermont's strong tradition of municipal home rule, described more fully in the broader Vermont government structure reference at the site index.

Professionals navigating permitting, regional infrastructure, or land use proceedings should verify current regional plan adoption dates directly with the applicable RPC, as plan cycles vary and conformance findings reference the version of the regional plan in effect at the time of application.
