Except as otherwise provided in this article, no structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone created by this article to a height in excess of the applicable height limit 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 Surface 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 center line.
B. Utility Runway Nonprecision Instrument Approach Surface 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 center line.
C. Runway Larger Than Utility Visual Approach Surface 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 center line.
D. Runway Larger Than Utility With A Visibility Minimum Greater Than 3/4 Mile Nonprecision Instrument Approach Surface 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 center line.
E. Runway Larger Than Utility With A Visibility Minimum As Low As 3/4 Mile Nonprecision Instrument Approach Surface 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 center line.
F. Precision Instrument Runway Approach Surface Zone: slopes 50 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 center line; thence slopes upward 40 feet horizontally for each foot vertically to an additional horizontal distance of 40,000 feet along the extended runway center line.
G. Transitional Surface Zones: slopes 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, extending to a height of 150 feet above the airport elevation which is 1,516 feet above mean sea level. In addition to the foregoing, when an airport has a precision instrument runway approach zone, there are established height limits sloping seven feet outward for each foot upward beginning at the sides of and at the same elevation as the approach surface, and extending to where they intersect the conical surface. Where the precision instrument runway approach zone projects beyond the conical zone, there are established height limits sloping seven feet outward for each foot upward beginning at the sides of and at the same elevation as the approach surface, and extending a horizontal distance of 5,000 feet measured at ninety-degree angles to the extended runway center line.
H. Horizontal Surface Zone: established at 150 feet above the established airport elevation or at a height of 1,666 feet above mean sea level.
I. Conical Surface Zone: slopes 20 feet outward for each foot upward beginning at the periphery of the horizontal surface and at 150 feet above the established airport elevation or at a height of 1,866 feet above mean sea level.
