Except as otherwise provided in this chapter, no structure shall be erected, altered, or maintained, and no tree shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone created by this chapter 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:
1. Utility Runway Non-precision Instrument Approach Zone. Slopes thirty-four feet (34') 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. Transitional Zones. Slope seven feet (7') 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 or at an elevation of 1,030 feet above mean sea level. In addition to the foregoing, there are established height limits sloping seven feet (7') 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 (7') 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 (90°) angles to the extended runway centerline.
3. Horizontal Zone. Established at 150 feet above the airport elevation or at an elevation of 1,030 feet above mean sea level.
4. Conical Zone. Slopes twenty feet (20') 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.
5. Excepted Height Limitations. Nothing in this chapter shall be construed as prohibiting the construction or maintenance of any structure or growth of any tree to a height up to fifty feet (50') above the surface of the land.
