North Carolina General Statutes
Article 4 - Model Airport Zoning Act.
§ 63-36 - Acquisition of air rights.

63-36. Acquisition of air rights.
In any case in which:
(1) It is desired to remove, lower, or otherwise terminate a nonconforming use; or
(2) The approach protection necessary cannot, because of constitutional limitations, be provided by airport zoning regulations under this Article; or
(3) It appears advisable that the necessary approach protection be provided by acquisition of property rights rather than by airport zoning regulations,
If any political subdivision, or if any board or administrative agency appointed or selected by a political subdivision, shall adopt, administer or enforce any airport zoning regulations which results in the taking of, or in any other injury or damage to any existing structure, such political subdivision shall be liable therefor in damages to the owner or owners of any such property and the liability of the political subdivision shall include any expense which the owners of such property are required to incur in complying with any such zoning regulations. (1941, c. 250, s. 8.)
