Except as otherwise provided in this section, no structure shall be erected, altered, or maintained in any zone created by this subchapter to a height in excess of the applicable height limitation herein established for such zone. Such applicable height limitations are hereby established for each of the zones in question as follows:
(A) Utility runway visual approach zone. Slopes 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 5,000 feet along the extended runway centerline.
(B) Utility runway nonprecision instrument approach zone. Slopes 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 5,000 feet along the extended runway centerline.
(C) Runway larger than utility visual approach zone. Slopes 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 5,000 feet along the extended runway centerline.
(D) Runway larger than utility with a visibility minimum greater than 3/4 mile nonprecision instrument approach zone. Slopes 34 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 10,000 feet along the extended runway centerline.
(E) Runway larger than utility with a visibility minimum as low as 3/4 mile nonprecision instrument approach zone. Slopes 34 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 10,000 feet along the extended runway centerline.
(F) Transitional zones. Slope seven feet outward for each foot upward beginning at the sides of and at the same elevation as the primary surface and the approach surface, and extending to a height of 150 feet above airport elevation which is 806 feet above mean sea level. In addition to the foregoing, there are established height limits sloping seven feet outward for each foot upward beginning at the sides of and the same elevation as the approach surface, and extending to where they intersect the conical surface.
(G) Horizontal zone. Established at 150 feet above the airport elevation or at a height of 956 feet above mean sea level.
(H) Conical zone. Slopes 20 feet outward for each foot upward beginning at the periphery of the horizontal zone and at 150 feet above the airport elevation and extending to a height of 350 feet above the airport elevation.
(I) Excepted height limitation. Nothing in this section shall be construed as prohibiting the construction or maintenance of any structure to a height up to 50 feet above the surface of the land, and where land is located below the approach or transitional surfaces.
