In order to prevent the creation or establishment of airport hazards, every political subdivision that has an airport hazard area within the area of its zoning jurisdiction shall adopt, administer, and enforce, under the police power and in the manner and upon the conditions prescribed in the Airport Zoning Act, airport zoning regulations for such airport hazard area. The regulations shall meet the minimum regulations as prescribed by the Division of Aeronautics of the Department of Transportation and may divide such area into zones and, within such zones, specify the land uses permitted and regulate and restrict the height to which structures may be erected and trees allowed to grow, except that a political subdivision or a joint airport zoning board provided for in section 3-304 may include modifications or exceptions to the airport zoning regulations adopted under the Airport Zoning Act that the political subdivision or joint airport zoning board deems appropriate. Such modifications and exceptions shall not be considered a conflict for purposes of section 3-306. The authority of a political subdivision to adopt airport zoning regulations shall not be conditional upon prior adoption of a comprehensive development plan or a comprehensive zoning ordinance.
