(A) In order to carry out the provisions of this subchapter, 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 the Lincolnton-Lincoln County Regional Airport. The zones are shown on the Lincolnton-Lincoln County Regional Airport Zoning Map consisting of one sheet, representing the current version on file in the Zoning Department, which is attached to the ordinance codified in this subchapter and made a part hereof. 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.
(B) The various zones are hereby established and defined as follows.
(1) Runway larger than utility with a visibility minimum greater than three-fourth mile nonprecision instrument approach zone. The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach zone expands outward uniformly to a width of 3,500 feet at a horizontal distance of 10,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
(2) Transitional zones. The transitional zones are the areas beneath the transitional surfaces.
(3) 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.
(4) 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. The conical zone does not include the transitional zone.
