63-31. Adoption of airport zoning regulations.

(a) Every political subdivision may adopt, administer, and enforce, under the police power and in the manner and upon the conditions hereinafter prescribed, airport zoning regulations, which regulations shall divide the area surrounding any airport within the jurisdiction of said political subdivision into zones, and, within such zones, specify the land uses permitted, and regulate and restrict the height to which structures and trees may be erected or allowed to grow. In adopting or revising any such zoning regulations, the political subdivision shall consider, among other things, the character of the flying operations expected to be conducted at the airport, the nature of the terrain, the height of existing structures and trees above the level of the airport, the possibility of lowering or removing existing obstructions, and the views of the agency of the federal government charged with the fostering of civil aeronautics, as to the aerial approaches necessary to safe flying operations at the airport.

(b) In the event that a political subdivision has adopted, or hereafter adopts, a general zoning ordinance regulating, among other things, the height of buildings, any airport zoning regulations adopted for the same area or portion thereof under this Article may be incorporated in and made a part of such general zoning regulations, and be administered and enforced in connection therewith, but such general zoning regulations shall not limit the effectiveness or scope of the regulations adopted under this Article.

(c) Any two or more political subdivisions may agree, by ordinance duly adopted, to create a joint board and delegate to said board the powers herein conferred to promulgate, administer and enforce airport zoning regulations to protect the aerial approaches of any airport located within the corporate limits of any one or more of said political subdivisions. Such joint board shall have as members two representatives appointed by the chief executive officer of each political subdivision participating in the creation of said board and a chairman elected by a majority of the members so appointed.

(d) The jurisdiction of each political subdivision is hereby extended to the promulgating, adopting, administering and enforcement of airport zoning regulations to protect the approaches of any airport or landing field which is owned by said political subdivision, although the area affected by the zoning regulations may be located outside the corporate limits of said political subdivision. In case of conflict with any airport zoning or other regulations promulgated by any political subdivision, the regulations adopted pursuant to this section shall prevail.

(e) All airport zoning regulations adopted under this Article shall be reasonable, and none shall require the removal, lowering, or other change or alteration of any structure or tree not conforming to the regulations when adopted or amended, or otherwise interfere with the continuance of any nonconforming use, except as provided in G.S. 63-32, subsection (a).

(f) A political subdivision may not adopt an airport zoning regulation in violation of G.S. 63A-18.
