The Southern NH Planning Commission is one of nine regional planning commissions in the State of New Hampshire. The Commission was formed under the New Hampshire Statutes in 1966. SNHPC serves as the coordinating agency for the planning initiatives of fourteen communities in the southern New Hampshire region.
The Commission is also the Metropolitan Planning Organization (MPO) for the region. The MPO is an organization that conducts transportation planning in a cooperative, comprehensive, and continuous manner. The Federal Highway Acts stipulate that highway construction funds in urbanized areas can only be utilized by states with an MPO in place.
