Definitions. As used in this Act: (a) "Air Installation Compatible Use Zone Study" means the study conducted by the United States Air Force that reaffirms the policy of promoting public health, safety, and general welfare in the areas surrounding Air Force bases. (b) "Clear zones and runway protection zones" mean the zones that have the highest potential for an aircraft accident among the safety zones designated by the United States Air Force around an Air Force base. (c) "Accident potential zones I" mean the zones that, other than clear zones and runway protection zones, have the highest potential for an aircraft accident among the safety zones designated by the United States Air Force around an Air Force base. (d) "Accident potential zones II" mean the zones that, other than clear zones and runway protection zones and accident potential zones I, have the highest potential for an aircraft accident among the safety zones established by the United States Air Force around an Air Force base. (e) "Sixty-five decibel A-weighted noise contour" means the noise level that has been determined by the United States Air Force to result from aircraft operations and flight tracks around an Air Force base. Section 10. County land use authority. Any county with a United States Air Force installation with runways of at least 7,500 feet in length has the authority to protect the safety of the community by controlling the use of land around that installation, notwithstanding any ordinance of or authority granted to any municipality. The county's land use authority is limited to the area designated in the Air Installation Compatible Use Zone Study adopted by the United States Air Force for that installation and the runways it occupies or uses. Section 15. County eminent domain powers. If a land use exists or a municipality approves a land use that is incompatible with the Air Installation Compatible Use Zone Study, and any portion of the affected land is within areas designated in the Air Installation Compatible Use Zone Study as clear zones and runway protection zones, accident potential zones I, or accident potential zones II, or is within the 65 decibel A-weighted noise contour, the county may use eminent domain to acquire either the fee simple title to that portion of the affected land or the easement rights in that portion of the affected land that are necessary for the compatible land use defined under the Air Installation Compatible Use Zone Study. If a municipality within those zones controls the use of land in a manner compatible with the Air Installation Compatible Use Zone Study, the county does not have eminent domain authority. Section 99. Effective date. This Act takes effect upon becoming law.
