Before any nonconforming structure may be replaced, substantially altered, or rebuilt within any airport approach zone, airport turning zone, or airport transition zone, a permit shall be secured authorizing such replacement or change. Such permit shall be granted except when the granting thereof would permit the establishment or creation of an airport hazard or permit a nonconforming use or structure to be made or become higher or become a greater hazard to air navigation than existed on the effective date of the applicable regulation thereunder. In the event of emergencies affecting the public welfare or safety, or the preservation of property, any nonconforming structure may be replaced or repaired without first obtaining a permit provided an application for a permit is filed with the County Division of Aviation within 24 hours after such department is first opened subsequent to the emergency.
