A single municipality may direct an appropriate officer, board, or body to acquire or lease real property or may set apart and use real property owned by the municipality which, in the judgment of its legislative body, is not needed for any other public use, whether originally acquired by condemnation or purchase. The site for an airport or landing field must be approved by the legislative body. Sections 601-604 of this title shall apply to a single municipality as well as to two or more municipalities, provided that the legislative body of each municipality shall provide for the action by resolution. A municipality of this State is authorized to join with a municipality of an adjacent state for the purpose of this subchapter in which instance the provisions of this subchapter shall apply except as to acquisition of property in an adjacent state by condemnation proceedings.
