Illinois Code § 13

§ 13.

Power to adopt airport zoning regulations. In order to prevent the creation or establishment of airport hazards, every political subdivision having an airport hazard area wholly or partly within its territorial limits may adopt, administer, and enforce, under the police power and in the manner and upon the conditions hereinafter prescribed, airport zoning regulations for that part of such airport hazard area which is within its territorial limits or which extends not more than two miles beyond its territorial limits. Every political subdivision which owns or controls an airport which is not located wholly or partly within its territorial limits may, in order to prevent the creation of airport hazards, adopt, administer, and enforce, under the police power and in the manner and upon the conditions hereinafter prescribed, airport zoning regulations for that part of such airport hazard area which extends not more than 2 miles from the boundaries of said airport and which regulations are related to the runways and facilities of such airport and shall not become effective until after such runways and facilities are installed or constructed; provided, however, that such zoning regulations shall not limit any existing use or require the reduction of the height of any existing structure without the owner's consent or the payment of just compensation for damages or loss resulting therefrom. Such regulations may divide such area into zones, and, within such zones, specify the land uses permitted and regulate and restrict the height to which structures and trees may be erected or allowed to grow.
