(A) Conforming uses only;
(B) All uses in the Airport Overlay Zones shall be subject to the regulations of this subchapter and prescribed development standards within the airport master plan, as amended;
(C) Creation of airport hazards prohibited;
(D) No variance, permit or use shall be allowed in the airport hazard area that would create or enhance an airport hazard;
(E) Use and operational limitations within the Airport Overlay Zones;
(F) No use shall be permitted which:
(1) Creates or tends to create electrical interference to navigational devices and communication between aircraft and airports;
(2) Creates or tends to create gas, smoke, dust, glare or other visual hazards in the atmosphere around airports or in the airport hazard area;
(3) Creates or tends to create structures that interfere with aircraft safety; and
(4) Creates or tends to create any type of hazard for the airport that would inhibit or constrain safe and acceptable airport operations.
(G) Except as exempted in division (H) below otherwise provided in this subchapter, no structure shall be erected, altered or maintained, and no tree shall be allowed to grow in any zone created by this subchapter to a height in excess of the applicable height limit herein established for such zone. Such applicable height limitations are hereby established for each of the zones in question as follows:
(1) Runway 17 Visual Approach Zone: one foot in height for each 20 feet in horizontal distance beginning at a point 200 feet from and at the centerline elevation of the end of the runway and extending a distance of 5,200 feet from the end of the Runway 17;
(2) Runway 35 Precision Instrument Approach Zone: one foot in height for each 50 feet in horizontal distance beginning at a point 200 feet from and at the centerline elevation of the end of the runway and extending a distance of 10,200 feet from the end of the runway;
(3) Transition Zone: one foot in height for each seven feet in horizontal distance beginning at any point 250 feet normal to and at the elevation of the centerline of the runway, extending 200 feet beyond each end thereof, and 500 feet normal to and at the elevation of the centerline of the runway, extending 200 feet beyond each end thereof, extending to a height of 150 feet above the airport elevation. In addition, there are established height limits of one foot vertical height for each seven feet horizontal distance measured from the edges of all approach zones for the entire length of the approach zone and extending upward and outward to the points where they intersect the horizontal or conical surfaces;
(4) Horizontal Zone: 150 feet above the airport elevation or a height of 4,225.5 feet above mean sea level (MSL); and
(5) Conical Zone: slopes 20 feet outward for each one foot upward beginning at the periphery of the horizontal zone and at 150 feet above the airport elevation 4,375.5 feet. MSL and extending to a height of 250 feet 4,725.5 feet. MSL feet above the airport elevation.
(H) (1) Any object that would be shielded by existing structures of a permanent and substantial character or by natural terrain or topographic features of equal or greater height, and would be located in the congested area of a city, town or settlement where it is beyond all reasonable doubt that the structure so shielded will not adversely affect safety in air navigation.
(2) Structures up to and including 35 feet in height above the ground level at its site where the ground elevation at its site is less than or equal to 35 feet below the height limitations defined in § 156.263(G) of this chapter, and is beyond all reasonable doubt that the structure will not adversely affect safety in air navigation. If in doubt, submission of FAA Form 7460-1, Notice of Proposed Construction (as described in this section) shall be used to determine its effect on safety in air navigation.
