§ 3-58. Airport zones.

In order to carry out the provisions of this division, there are hereby created and established certain zones which include all of the land lying within the instrument approach zones, noninstrument approach zones, transition zones, horizontal zone, and conical zone.

Such areas and zones are shown on Esler Regional Airport Zoning Map consisting of one sheet, prepared by Domingue, Szabo & Associates, Inc., and dated August 27, 1976, which is made a part hereof. The various zones are hereby established and defined as follows:

(1)

Precision instrument runway approach zone. An instrument approach zone is established at the end of runway 26 for instrument landings and takeoffs. The instrument approach zone shall have a width of one thousand (1,000) feet at a distance of two hundred (200) feet beyond the end of the runway, widening thereafter uniformly to a width of sixteen thousand (16,000) feet at a distance of fifty thousand two hundred (50,200) feet beyond the end of the runway, its center line being the continuation of the center line of the runway.

(2)

Nonprecision instrument runway approach.

(a)

This approach zone is established at the end of runway 8 for landings and takeoffs. 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 three thousand five hundred (3,500) feet at a horizontal distance of ten thousand (10,000) feet from the primary surface. Its center line being the continuation of the center line of the runway.

(b)

This approach is established at each end of runway 14-32 for landings and takeoffs. 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 center line being the continuation of the center line of the runway.

(3)

Transitional zones. These zones are hereby established as the area beneath the transitional surfaces. These surfaces extend outward and upward at ninety-degree angles to the runway center line and the runway center line 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 zones for those portions of the precision approach zones which project through and beyond the limits of the conical surface extend a distance of five thousand (5,000) feet measured horizontally from the edge of the approach zones and at ninety-degree angles to the extended runway center line.

(4)

Horizontal zone. The horizontal zone is hereby 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. A conical zone is hereby established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a distance of four thousand (4,000) feet. The conical zone does not include the instrument approach zones and transition zones.
