329.2  Airport hazards contrary to public interest.
  It is hereby found that an airport hazard endangers the lives and property of users of the airport and of occupants of land and other persons 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:
  1.  That the creation or establishment of an airport hazard is a public nuisance and an injury to the community served by the airport in question.
  2.  That it is necessary in the interest of the public health, safety, and general welfare that the creation or establishment of airport hazards be prevented.
  3.  That this should be accomplished, to the extent legally possible, by proper exercise of the police power.
  4.  That 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 municipalities may raise and expend public funds, as an incident to the operation of airports, to acquire land or property interests therein.
