Except as exempted in Paragraph H of this Section otherwise provided in this Ordinance, no structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone created by this Ordinance 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 16 Visual Approach Zone – 1 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 16.
2. Runway 34 Precision Instrument Approach Zone – 1 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 – 1 foot in height for each 7 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 1 foot vertical height for each 7 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 4225.5 feet above mean sea level (MSL).
5. Conical Zone - Slopes twenty (20) feet outward for each one (1) foot upward beginning at the periphery of the horizontal zone and at 150 feet above the airport elevation (4,375.5 ft. MSL) and extending to a height of 350 feet above the airport elevation (4,725.5 ft. MSL).
H. Exemptions to height limitation:
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 Section 4-1-090 (G) of this Ordinance, 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 Section 4-1-110 of this Code) shall be used to determine its effect on safety in air navigation.
