§ 6-51. Zones

In order to carry out the provisions of this article, there are hereby created and established certain zones which include all of the land and water lying beneath the approach surfaces, transition surfaces and horizontal surface as they apply to the Granite Shoals Airport; provided, however, that the term "zones," as used in this chapter, should not be construed to mean "zoning districts" as provided by the city comprehensive zoning ordinance. An area located in more than one of the following zones is considered to be only in the zone with the more restrictive height limitation. The various zones are hereby established and defined as follows:

(1) Approach zones.

a. Runway 20. The approach zone is established beneath the approach surface at the end of runway 20 on Granite Shoals Airport for visual landings and takeoffs. The inner edge of the approach zone shall have a width of 50 feet which coincides with the runway, widening thereafter uniformly to a width of 2,150 feet at a horizontal distance of 3,000 feet beyond the runway, its centerline being the continuation of the centerline of the runway.

b. Runway 2. The approach zone is established beneath the approach surface at the end of runway 2 on Granite Shoals Airport for visual landings and takeoffs. The inner edge of the approach zone shall have a width of 50 feet which coincides with the width of the runway, at its displaced threshold which is 140 feet north of the south airstrip boundary, widening thereafter uniformly to a width of 2,150 feet at a horizontal distance of 3,000 feet beyond the displaced threshold, its centerline being the continuation of the centerline of the runway.

(2) Transition zones. Transition zones are hereby established beneath the transition surfaces adjacent to the runway as indicated on the zoning map. Transition surfaces extend outward and upward at right angles to the runway edges and the runway edges extended at a slope of seven to one from the runway edge and from the sides of the approach surfaces.

(3) Horizontal zone. A horizontal zone is the area beneath a horizontal plane 150 feet above the established airstrip elevation. The east and west boundaries are located 8,000 feet from the airport reference point and parallel to the runway. The north and south boundaries are located 8,000 feet from the airstrip reference point and at 90 degrees to the extended runway centerline.
