HomeMy WebLinkAboutC.054.93011_1706 (2)The width of the primary surface is 1,000 feet wide and centered on the runway centerline. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline. Runway means a defined area on an airport prepared for landing and takeoff of aircraft along its length. Structure means any object, constructed or installed by human labor, including, but without limitation, buildings, towers, smokestacks and overhead transmission lines. Transdmal Surfaces means surfaces that extended outward at 90 degree angles to the runway centerline and the runway centerline extended at a slope of seven (7) feet horizontally for each foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces. Transitional surfaces for those portions of the precision approach surfaces, which project through and beyond the limits of the conical surface, extend a distance of 5,000 feet measured horizontally from the edge of the approach surface and at 90 degree angles tot he extended runway centerline. Tree means any object of natural growth. Section 103. Airport zones. In order to carry out the purposes of this ordinance, there are hereby created and established certain zones, which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to Statesville Regional Airport. Such zones are shown on the Height Zoning Map, prepared by W.K. Dickson dated September 2007, which is attached to this ordinance and made part hereof. An area located in more than one (1) 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: (a) Non -Precision Instrument Approach Zone. The inner edge of this approach zone coincides with the width of the primary surface and is 1,000 feet wide. The approach zone expands outward uniformly at a slope of 34 feet horizontally for every 1 foot vertically to a width of 4,000 feet at a horizontal dance 10,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway. (b) Precision Instrument Runway Approach Zone. The inner edge of this approach zone coincides with the width of the primary surface and is 1,000 feet wide. The approach zone expands outward uniformly at a slope of 50 feet horizontally for every 1 foot vertically for a horizontal distance of 10,000 feet, then at a slope of 40 feet horizontally for every 1 foot vertically to a width of 16,000 feet for a horizontal distance of 50,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway. (c) Primary Approach Zones. The Primary Approach Zones begin at each runway end starting at the pavement edge at a width of 1,000 feet and extend to a width of 6,940 for a horizontal distance of 20,000 feet. This zone provides that no structure may be built within this zone that rises above the Runway End elevation of 958.7 on the Primary Approach Zone to Runway End 10 or 957.7 on the Primary Approach Zone to Runway End 28. (d) Primary Zone. The primary zone is the area beneath the primary surface. This zone extends 200 feet beyond each end of the runway, has a width of 1,000 feet, and is centered on the runway centerline. (e) Transitional Zones. The transitional zones are the areas beneath the 7 foot horizontal to 1 foot vertical transitional surface. (f) Horizontal Zone. The horizontal zone is established by swinging arcs of 10,000 feet radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach and transitional zones. This zone contains the Horizontal Surface, which is located 150 feet above the established airport elevation. (g) Conical Zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a horizontal distance of 4,000 feet. This zone contains the Conical Surface, which contains a slope of 20 horizontally for every 1 foot vertically. Section 104. Height limitations. No structure or tree shall be erected, altered, allowed to grow or maintained in the airport zones to a height in excess of the height limit as determined by the aerial contours appearing on the Height Zoning Map or referred to in Section 103. Except for the City of Statesville, the property owner of a tree, determined to be an airport hazard, shall not be responsible for bringing such tree into conformance with this ordinance. Section 105. Use restrictions. Notwithstanding any other provisions of this Ordinance, no use may be made of land or water within any zone established by this Ordinance in such a manner as to create electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult to for pilots to distinguish between airport lights and others, resulting in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards, or otherwise in any way endanger or interfere with the landing, takeoff, or maneuvering of aircraft intending to use the airport Section 106. Nonconforming structures. Subject to the provisions of subsection (a) of Section 108, the regulations prescribed in Section 104 shall not be construed to require the removal, lowering or other change or alteration of any structure or tree not conforming to the regulations as of December 3, 2003. Section 107. Variances. Variances may be permitted by the board of adjustment where a literal application or enforcement of the regulations prescribed by this ordinance would result in practical difficulty or unnecessary hardship and the relief granted would not be contrary to the public interest or impair the utility of the airport, but do substantial justice and be in accordance with the spirit of this ordinance.
