§ 1½-15. 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 jurisdiction land lying within the instrument approach zones, noninstrument approach zones, and transition zones, horizontal zones and conical zones. Such areas and zones are shown on the Monroe Municipal Airport Hazard Zoning Map prepared by Jenkins and Madden Engineering dated September 4, 1974, Airport Master Plan maps, made a part of this article.

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. The various zones are 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 being 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 being 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 being the continuation of the centerline of the runway.

(4)

Runway larger than utility with a visibility minimum greater than three-fourths 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 being the continuation of the centerline of the runway.

(5)

Runway larger than utility with a visibility minimum as low as three-fourths 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 being 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.

(7)

Transitional zones. These zones are hereby established as the area beneath the transitional surfaces. These surfaces extended outward and upward at ninety-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 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 centerline.

(8)

Horizontal zone. The horizontal zone is hereby established by swinging arcs of five thousand (5,000) feet radii for all runways designated as utility or visual and ten thousand (10,000) feet radii for all other runways 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 hereby 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. The conical zone does not include the precision instrument approach zones and the transitional zones.
