N.D. Cent. Code § 11-33-04
The board of county commissioners of any county desiring to avail itself of the powers conferred by this chapter shall establish, by resolution, a county planning commission to recommend the boundaries of the various county zoning districts and appropriate regulations and restrictions to be established therein. In counties with three-member boards of county commissioners, the planning commission consists of seven members, of whom at least one must be appointed from the governing body of the city that is the county seat, and of whom at most one may be appointed from the board of county commissioners. In counties with five-member boards of county commissioners the planning commission consists of nine members, of whom at least two must be appointed from the governing body of the city that is the county seat, and of whom at most two may be appointed from the board of county commissioners. The term of an ex officio member is coterminous with the member's term in the underlying office. The remaining members shall be appointed from the county at large. In counties that elect county commissioners from districts, at least one at large member of the planning commission must be appointed from each district. When appointments to said commission are first made, three members at large shall be appointed for a two-year term and two members at large for a four-year term, after which all subsequent appointments for members at large shall be for a four-year term. Appointments to fill vacancies shall be for the unexpired portion of the term. All appointments to the county planning commission shall be made by the board of county commissioners.
