The purpose of this chapter shall be to:
A. Exercise, to the fullest extent possible, the powers granted to municipalities under the code of Iowa, as amended, and to codify existing regulations of the federal aviation administration relating to land uses incompatible with or constituting a hazard to aviation at the Iowa City municipal airport.
B. Promote the public health, safety, order, convenience, prosperity and general welfare through the prevention of obstructions and noncompatible land uses, to the extent legally possible, by proper exercise of the police power, without compensation.
C. Achieve the mitigation of noncompatible uses and hazards to safe air navigation through prevention, removal, or alteration, through the marking and lighting of obstructions, which are public purposes for which the city of Iowa City and Johnson County may raise and expend public funds, or through the acquisition of land or interests in land; to that end, the city council of Iowa City and the board of supervisors of Johnson County hereby declare that:
1. A hazard created by failure to comply with the provisions of this chapter may be abated in the manner prescribed by law for the abatement of public nuisances; and
2. Neither political subdivision shall become liable for the expenditure of its public funds unless such expenditure shall have been approved in advance by its governing body. (Ord. 02-4055, 12-10-2002)
