Ohio Rev. Code § 4563.031
Within the approach, transitional, inner horizontal, and conical areas at a publicly owned airport, an airport zoning board constituted under section 4563.03 of the Revised Code may adopt, administer, and enforce zoning regulations, in addition to its regulations adopted under section 4563.03 of the Revised Code, in order to ensure the safety of persons occupying or using such areas and the security of property located within such areas. Airport zoning regulations may divide such approach, transitional, inner horizontal, and conical areas into zones, and within such zones, regulate and restrict land use in order to minimize injury, loss of life, and hazards to the safety of persons or to the security of property within such zones, and may include regulations governing population density and concentration of persons within such zones.
Prior to initial zoning under this section, the procedures set forth in sections 4563.05, 4563.06, and 4563.08 of the Revised Code for establishing the boundaries of the various zones and adopting the regulations therefor, shall be followed. "Approach area," "transitional area," "inner horizontal area," or "conical area," respectively, means any area of land adjacent to an airport and within an airport hazard area, which has been declared to be an "approach area," "transitional area," "inner horizontal area," or "conical area" by the office of aviation, based upon the approach plan for the airport. No zone established under this section may include any area outside such approach, transitional, inner horizontal, and conical areas.
