N.J. Stat. § 40:8-5
Private property needed by any municipality for an airport or landing field shall be acquired by purchase if the municipality is able to agree with the owners on the terms thereof, and otherwise by condemnation, in the manner provided by the law under which the municipality is authorized to acquire real property for public purposes other than street purposes, or, if there be no such law, in the manner provided for and subject to the provisions of the "Eminent Domain Act of 1971," P.L. 1971, c.361 (C.20:3-1 et seq.). The purchase price or award for real property acquired for an airport or landing field may be paid for by appropriation of moneys available therefor or wholly or partly from the proceeds of the sale of bonds of the municipality, as the governing body of such municipality shall determine. Such bonds shall be authorized and issued in accordance with the provisions of the "Local Bond Law," (N.J.S. 40A:2-1 et seq.).
