§ 5. Airport Zone Height Limitations and Restrictions.
Except as otherwise provided in these Regulations, no structure, tree or natural object shall be erected, altered, allowed to grow or be maintained in any of the zones created by these Regulations to a height in excess of the applicable height limit herein established for such zone. The following height limitations are hereby established for each of the zones in question, as follows:
a.
Utility Runway Visual Approach Zone for Runways 3 and 32. The height limitation is based upon a slope of 20:1 so that the height limitation moves 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extends a horizontal distance of 5,000 feet along the extended runway center line. The following examples or guidelines are used in order to compute the height limitation in this zone:

b.
Utility Runway Non Precision Instrument Approach Zone (Runways 21 and 14). The height limitation for this zone is calculated using a slope of 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface of the runway and extends to a horizontal distance of 5,000 feet along the extended runway center line. The following guidelines are used in order to compute the height limitation in this zone:

c.
Runway Larger than Utility Visual Approach Zone (Runway 8). The height limitation for this zone is calculated using a slope of 20 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface of the runway and extends to a horizontal distance of 5,000 feet along the extended runway center line. The following guidelines are used in order to compute the height limitation in this zone:

d.
Runway Larger than Utility with Visibility Minimum Greater than Three Fourth (3/4) Mile Non Precision Instrument Approach Zone for Runway 26. The height limitation for this zone shall be calculated based upon a radio of 34:1 so that a slope of 34 feet outward for each foot upward would be used beginning at the end of and at the same elevation as the primary surface for Runway 26, and extending to a horizontal distance of 10,000 feet along the extended runway center line of Runway 26. Using this slope the following height limitations would be in effect for the distance or prorated portion therein indicated as follows:

e.
Runway Larger than Utility with a Visibility Minimum as Low as Three-Fourth (3/4) Mile Non Precision Instrument Approach Zone. The height limitation for this approach zone would be calculated using a radio of 34:1 so that for each 34 feet outward there would be a height limitation of 1 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. The following guidelines are provided in order to compute the height limitation in this zone:

f.
Precision Instrument Runway Approach Zone for Runway 26. The height limitation for this approach zone would be calculated based upon a radio of 34:1 so that for each 34 feet outward there would be a height limitation of 1 foot upward beginning at the end of and at the same elevation as the primary surface at the end of Runway 26 and extending to a horizontal distance of 10,000 feet along the extended runway center line. This zone then slopes upward 40 feet horizontally for each foot vertically to an additional horizontal distance of 40,000 feet along the extended runway center line. The following is a calculation of height limitations and restrictions based upon horizontal distances from the end of the primary surface:

g.
Transitional Zones. The height limitation for transitional zones is calculated using a radio of 7:1, so that there is a slope of 7 feet outward for each foot upward beginning at the sides of and at the same elevation at the primary surface and the approach surface to the runways, and extending to a height of 150 feet above the Airport Elevation which is 161 feet above mean sea level. In addition to the foregoing, there are hereby established height limits sloping 7 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. Where the precision instrument runway approach zone projects beyond the conical zone, there are hereby established height limits sloping 7 feet outward for each foot upward beginning at the sides of and the same elevation as the approach surface, and extending a horizontal distance of 5,000 feet measured at 90 degree angles to the extended runway center line.
h.
Horizontal Zone. There is hereby established a height limitation of 150 feet above the Airport Elevation or at a height of 161 feet above mean sea level within the horizontal zone.
i.
Conical Zone. The height limitation within the conical zone is hereby established based upon a slope of 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 or at a height of 361 feet above mean sea level.
