Ohio Revised Code Title XLV. Motor Vehicles Aeronautics Watercraft § 4563.03

(A) When an airport is publicly owned and all airport hazard areas appertaining to such airport are located inside the territorial limits of one political subdivision, the legislative authority of the political subdivision shall constitute the airport zoning board. Such legislative authority, acting as the airport zoning board, may adopt, administer, and enforce airport zoning regulations for such airport hazard area. Airport zoning regulations may divide an airport hazard area into zones, and, within such zones, regulate and restrict land uses which by their nature constitute airport hazards, and regulate and restrict the height to which structures may be erected or objects of natural growth may be allowed to grow. An obstruction of air space in an airport hazard area rising to a height not in excess of forty feet above the established elevation of the airport, or three feet for each one hundred feet or fraction thereof its location is distant from the nearest point in the perimeter of the airport, whichever is greater, shall be prima facie reasonable.

(B) When an airport is publicly owned and any airport hazard area appertaining to such airport is located in more than one political subdivision, the board of county commissioners of each county in which such airport or such airport hazard area may exist, shall constitute the airport zoning board, which shall have the same power to adopt, administer, and enforce airport zoning regulations as provided in division (A) of this section. The board shall elect its own chairman.
