§ 6-71. Established.

(a)

In order to carry out the provisions of this article, there are hereby created and established certain zones which include all of the land lying beneath the approach surface, transitional surface, horizontal surfaces and conical surfaces as they apply to the county airport. Such zones are shown on the official Rowan County Airport Zoning Map prepared by Rowan County Planning and dated June 26, 1989, which is adopted and incorporated herein by reference. Amendments to this map shall be made and posted in accordance with section 6-141.

(b)

Should the official county airport zoning map be lost, destroyed or damaged, the director may have a new map drawn on acetate or other durable material from which prints can be made. No further board of commissioners' authorization or action is required so long as no zone boundaries are changed in this process.

(c)

An area located in more than one (1) of the following zones is considered to be only in the one (1) with the more restrictive height limitation. The various zones are hereby established and defined as follows:

(1)

Runway larger than utility with a visibility minimum greater than three-fourths mile nonprecision instrument approach zone. The inner edge of this approach zone coincides with the width of the primary surface and is five hundred (500) feet wide. The approach zone expands outward uniformly to a width of three thousand five hundred (3,500) feet at a horizontal distance of ten thousand (10,000) feet from the primary surface. Its centerline is the continuation of the centerline of the runway.

(2)

Precision instrument runway approach zone. The inner edge of this approach zone coincides with the width of the primary surfaces and is one thousand (1,000) feet wide. The approach zone expands outward uniformly to a width of sixteen thousand (16,000) feet at a horizontal distance of fifty thousand (50,000) feet from the primary surface. Its centerline is the continuation of the centerline of the runway.

(3)

Transitional zones. The transitional zones are the areas beneath the transitional surfaces.

(4)

Horizontal zone. The horizontal zone is established by swinging arcs of ten thousand (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.

(5)

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 four thousand (4,000) feet.
