Acquisition of air rights.

If a nonconforming obstruction is determined to be an airport hazard and the owner will not remove, lower, or otherwise eliminate it; the approach protection necessary cannot, because of constitutional limitations, be provided by airport zoning regulations under this chapter; or it appears advisable that the necessary approach protection be provided by acquisition of property rights rather than by airport zoning regulations, the political subdivision within which the property or nonconforming obstruction is located, or the political subdivision owning or operating the airport or being served by it, may acquire, by purchase, grant, or condemnation in the manner provided by chapter 73, such property, air right, avigation easement, or other estate, portion, or interest in the property or nonconforming obstruction or such interest in the air above such property, in question, as may be necessary to effectuate the purposes of this chapter, and in so doing, if by condemnation, to have the right to take immediate possession of the property, interest in property, air right, or other right sought to be condemned, at the time, and in the manner and form, and as authorized by chapter 74. In the case of the purchase of any property, easement, or estate or interest therein or the acquisition of the same by the power of eminent domain, the political subdivision making such purchase or exercising such power shall, in addition to the damages for the taking, injury, or destruction of property, also pay the cost of the removal and relocation of any structure or any public utility that is required to be moved to a new location.
