(A) Except as otherwise provided in this section, no structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any airport zone created by this section to a height in excess of the applicable height limit herein established for such zone.
(B) Such applicable height limitations are established for each of the zones in question as follows:
(1) Nonprecision instrument approach zone (for runway larger than utility with a visibility minimum greater than three-fourths of a mile). 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;
(2) Precision instrument runway approach zone. Runway having an existing instrument procedure utilizing an Instrument Land System (ILS) or a Precision Approach Radar (PAR);
(3) Transitional 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, and extending to a height of 150 feet above the airport elevation, which is 199 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 at the same elevation as the approach surface, and extending to where they intersect the conical surface;
(4) Horizontal zone. Established at 150 feet above the airport elevation or at a height of 349 feet above mean sea level;
(5) 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 (549 feet above mean sea level); and
(6) Excepted height limitations. Nothing in this section shall be construed as prohibiting the construction or maintenance of any structure, or growth of any tree to a height up to 50 feet above the surface of the land.
