Part 9 - Airport Hazards

R 259.291 Applications.
Rule 291. (1) Application shall be made for a commission permit, unless otherwise authorized in these rules, before a structure, natural growth, or other object shall be erected, rebuilt, altered, allowed to grow or maintained within the areas described in R 259.292 and R 259.293, which will result in an object extending more than 500 feet above the highest point of land within a 1 mile radius from the object.
(2) No application shall be required for the emergency repair, alteration, or replacement of public utility structures, other than buildings when the height of such structures will not be increased. Any circumstances calling for immediate action or remedy in the repair, alteration, or replacement of public utility structures shall be deemed an emergency.
History: 1954 ACS 52, Eff. Nov. 15, 1967; 1979 AC.

R 259.292 Zoning ordinances.
Rule 292. (1) In areas surrounding a public use airport for which zoning ordinances or resolutions have not been adopted by local units of government, no person shall erect, add to the height of, or replace any object within an area lying 500 feet on either side of the centerline of a runway or landing strip for a distance of 2 miles from the nearest boundary of a public use airport, which will result in an object extending higher than the height determined by the ratio of 20:1 between the nearest boundary of the airport and the object.
(2) In areas for which zoning ordinances or resolutions have been adopted by local units of government, no person shall erect, add to the height of, or replace an object except as authorized by the local zoning ordinance. Outside of locally zoned territory and within an area determined by the extensions of the approach surface and the transitional surface on the same slope ratios established under the local zoning ordinance or resolution, but not to exceed a slope ratio of 40:1 for the approach surface, or 7:1 for the transitional surface, to a point where the extended approach and transitional surfaces intersect the 500-foot level described in R 259.291, no object shall be erected, altered by increasing its height, or replaced until a permit therefor has been obtained from the commission.
History: 1954 ACS 52, Eff. Nov. 15, 1967; 1979 AC.

R 259.293 Nonconforming structures and trees.
Rule 293. These rules do not require removal, lowering, change, or alteration of a structure, vegetation, or other object not conforming to these rules as of their effective date. However, the owner of a nonconforming object shall without expense provide or permit installation, operation, and maintenance of markers and lights deemed necessary by the commission to indicate the presence of airport hazards. Where an airport hazard area exists in connection with a public use airport, the commission shall define and determine the airport hazard area and certify such determination to the political subdivision where the airport is located, and to the airport owner or operator.
History: 1954 ACS 52, Eff. Nov. 15, 1967; 1979 AC.

R 259.294 Abatement of hazards.
Rule 294. An encroachment upon an airport protection area arising out of the erection, rebuilding, alteration, growth, or maintenance of a structure, vegetation, or other object constitutes a public nuisance and may be abated.
History: 1954 ACS 52, Eff. Nov. 15, 1967; 1979 AC.

R 259.295 Conflicting rules.
Rule 295. If these rules conflict with other regulations applicable to the same area, whether the conflict is with respect to the height of structures, vegetation, or other objects, or any other matter, those limitations or requirements determined by the commission to be most conducive to airport and air travel safety shall prevail and govern.
History: 1954 ACS 52, Eff. Nov. 15, 1967; 1979 AC.
