§ 3-13. Airport 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 lying beneath the approach surfaces, transitional surfaces, horizontal surfaces and conical surfaces as they apply to the airport. Such zones are shown on the airport zoning map prepared by VTN Louisiana, Inc., and dated December 15, 1979, which is on file in the clerk's office and made a 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:

(1)

Utility runway visual approach zone: The inner edge of this approach zone coincides with the width of the primary surface and is two hundred fifty (250) feet wide. The approach zone expands outward uniformly to a width of one thousand two hundred fifty (1,250) feet at a horizontal distance of five thousand (5,000) feet from the primary surface. Its centerline is the continuation of the centerline of the runway.

(2)

Utility runway 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 two thousand (2,000) feet at a horizontal distance five thousand (5,000) feet from the primary surface. Its centerline is the continuation of the centerline of the runway.

(3)

Runway larger than utility visual 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 one thousand five hundred (1,500) feet at a horizontal distance of five thousand (5,000) feet from the primary surface. Its centerline is the continuation of the centerline of the runway.

(4)

Runway larger than utility with a visibility minimum greater than three-quarter (¾) 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 often thousand (10,000) feet from the primary surface. Its centerline is the continuation of the centerline of the runway.

(5)

Runway larger than utility with a visibility minimum as low as three-quarter (¾) mile nonprecision instrument approach zone: The inner edge of this approach zone coincides with the width of the primary surface and is one thousand (1,000) feet wide. The approach zone expands outward uniformly to a width of four thousand (4,000) 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.

(6)

Precision instrument runway approach zone: The inner edge of this approach zone coincides with the width of the primary surface 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.

(7)

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

(8)

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.

(9)

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.
