Mississippi Regional Planning Commissions: Districts, Coordination, and Development

Mississippi's 10 regional planning commissions (RPCs) function as the primary multi-jurisdictional coordinating bodies between county and state government, administering federal and state programs across defined geographic districts. These entities hold statutory authority under Mississippi Code Annotated § 17-1-31 and serve as the operational interface for land use planning, transportation coordination, workforce development, and grant administration across the state's 82 counties. Understanding the district structure, member composition, and functional scope of each commission is essential for county officials, state agency staff, federal grant administrators, and private-sector entities seeking regional approvals or coordination. The Mississippi Government Authority provides the broader structural reference within which RPCs operate.

Definition and scope

Regional planning commissions in Mississippi are quasi-governmental bodies created by voluntary agreement among member counties and municipalities under state enabling legislation. Each RPC serves a defined multi-county district, with membership typically drawn from county board of supervisors representatives, municipal elected officials, and governor-appointed members.

The 10 commissions and their general service areas are:

Three Rivers Planning and Development District — Marshall, Benton, Alcorn, Prentiss, Tishomingo, Tippah, Union, and Lee counties (northeast Mississippi)
North Central Mississippi Regional Planning and Development District — Calhoun, Chickasaw, Choctaw, Clay, Itawamba, Lafayette, Monroe, Pontotoc, Webster, and Yalobusha counties
Golden Triangle Planning and Development District — Lowndes, Noxubee, and Oktibbeha counties
East Central Mississippi Planning and Development District — Clarke, Jasper, Kemper, Lauderdale, Leake, Neshoba, Newton, Scott, and Winston counties
Southern Mississippi Planning and Development District — Covington, Forrest, Greene, Jones, Lamar, Marion, Perry, and Wayne counties
Mississippi Gulf Coast Regional Planning Commission — Hancock, Harrison, and Jackson counties
Southwest Mississippi Regional Planning Commission — Adams, Amite, Claiborne, Copiah, Franklin, Jefferson, Jefferson Davis, Lawrence, Lincoln, Pike, Simpson, Walthall, and Wilkinson counties
Central Mississippi Planning and Development District — Hinds, Madison, Rankin, Smith, and Yazoo counties
Delta Planning and Development District — Bolivar, Carroll, Coahoma, Grenada, Holmes, Humphreys, Issaquena, Leflore, Montgomery, Panola, Quitman, Sharkey, Sunflower, Tallahatchie, Tate, Tunica, Warren, and Washington counties
Southeast Mississippi Regional Planning and Development District — Forrest, George, Greene, Jones, Lamar, Marion, Perry, Stone, and Wayne counties (overlapping service arrangements apply in portions of southern Mississippi)

Each commission is governed by a board whose composition is governed by Mississippi Code Annotated § 17-1-3, which authorizes member local governments to designate representatives.

How it works

RPCs operate through direct contractual relationships with federal agencies — principally the U.S. Department of Housing and Urban Development (HUD), the Economic Development Administration (EDA), and the U.S. Department of Transportation — as well as state agencies including the Mississippi Development Authority and the Mississippi Department of Transportation.

Program administration follows a structured intake and reporting cycle:

Grant identification — The RPC identifies eligible federal or state funding sources applicable to member jurisdictions.
Application preparation — Staff assist member counties or municipalities with application development, environmental review, and compliance documentation.
Award management — Upon award, the RPC serves as the fiscal agent or technical advisor, depending on program rules.
Performance reporting — Quarterly and annual reports are submitted to funding agencies; RPC staff maintain audit-ready documentation under federal Uniform Guidance (2 CFR Part 200).
Regional plan updates — Comprehensive economic development strategies (CEDS), required by EDA regulations at 13 CFR Part 303, are updated on a 5-year cycle.

RPCs also serve as designated Metropolitan Planning Organizations (MPOs) in some districts, or work alongside separately constituted MPOs where federal transportation planning thresholds are met in urbanized areas exceeding 50,000 in population, per 23 U.S.C. § 134.

Common scenarios

Scenario 1: County infrastructure grant administration
A rural county in the Delta district with fewer than 5,000 residents lacks qualified professionals capacity to administer a Community Development Block Grant (CDBG) funded water system project. The Delta Planning and Development District serves as sub-recipient and fiscal agent, processing drawdown requests, maintaining procurement records, and submitting performance reports to the Mississippi Development Authority, which administers the state CDBG program under HUD allocation.

Scenario 2: Comprehensive economic development strategy
Under EDA requirements, each designated Economic Development District (EDD) must maintain a CEDS. The RPC convenes stakeholder committees drawn from member counties — which in the Golden Triangle district span Lowndes, Noxubee, and Oktibbeha counties — to update strategy documents, set five-year investment priorities, and document distress indicators required for EDA designation status.

Scenario 3: Transportation planning coordination
In districts containing urbanized areas, the RPC coordinates with state and municipal transportation agencies to satisfy federal metropolitan and statewide planning requirements. This involves convening technical committees, reviewing Transportation Improvement Programs (TIPs), and ensuring consistency between local capital budgets and the Statewide Transportation Improvement Program maintained by MDOT.

Decision boundaries

RPC authority vs. county government authority
RPCs hold no general police power and cannot impose zoning, tax assessments, or land use regulations on member jurisdictions. Those powers remain with county boards of supervisors and municipal governing authorities. The RPC's role is advisory, coordinative, and administrative — not regulatory over private land use. For the structure of county authority in Mississippi, see Mississippi county government structure.

RPC scope vs. special district scope
Mississippi special districts — including water and sewer authorities, port authorities, and school districts — operate under separate statutory frameworks and are not subordinate to RPCs. Where special district service areas overlap with RPC district boundaries, coordination occurs voluntarily or through specific grant program requirements, not by hierarchical mandate.

Scope and geographic coverage limitations
This page covers RPCs operating within Mississippi's 82-county geographic boundary under state and federal enabling law. It does not address interstate regional bodies such as the Delta Regional Authority (which spans portions of 8 states), federally chartered development banks, or planning activities governed solely by tribal government authorities. Federal tribal lands within Mississippi are not within RPC jurisdiction. Activities governed exclusively by the Mississippi Legislative Branch through direct appropriation — without RPC intermediation — also fall outside the administrative scope described here.
