Chapter 6 - Airport Zoning.
Section 4-6-3 - Airport Hazards Contrary to Public Interest; Elimination, Alteration, etc., of Hazards Declared Public Purpose.

It is hereby found that an airport hazard endangers the lives and property of users of the airport and of occupants of land in its vicinity and also, if of the obstruction type, in effect reduces the size of the area available for the landing, taking-off and maneuvering of aircraft, thus tending to destroy or impair the utility of the airport and the public investment therein. Accordingly, it is hereby declared:

It is further declared that both the prevention of the creation or establishment of airport hazards and the elimination, removal, alteration, mitigation or marking and lighting of existing airport hazards are public purposes for which political subdivisions may raise and expend public funds and acquire land or property interests therein.
