Chapter 4 - Municipal Airports and Regulations.
Section 4-4-5 - Methods of Acquisition.

Whenever, in the judgment of the council or other governing body of any municipality of this state, it shall appear necessary or expedient for such municipality to acquire privately owned lands for airport uses, either within or without the geographical limits thereof, such municipality shall have power to acquire the same in fee simple by exercise of the right of eminent domain, by purchase or by gift.
