Article VII. AIRPORT ZONE HEIGHT LIMITATIONS  


Except as otherwise provided in this ordinance, no structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone created by this ordinance to a height in excess of the applicable height limitations which are hereby established for each of the zones in question as follows:

(1)

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.

(2)

Runway larger than utility with a visibility minimum greater than three-fourths-mile non-precision 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.

(3)

Runway larger than utility with a visible minimum as low as three-fourths-mile non-precision 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.

(4)

Precision instrument runway approach 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 centerline; thence slopes upward 40 feet horizontally for each foot vertically to an additional horizontal distance of 40,000 feet along the extended runway centerline.

(5)

Transitional zones: Slopes seven feet outward for each foot upward beginning at the side 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 693.40 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. 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 as a horizontal distance of 5,000 feet measured at 90-degree angles to the extended runway centerline.

(6)

Horizontal zone: Established at 150 feet above the airport elevation or at a height of 843.40 feet above mean sea level.

(7)

Conical zone: Slopes 20 feet outward for each foot upward beginning at the periphery of the horizontal zone and a 150 feet above the airport elevation and extending to a height of 350 feet above the airport elevation.

(8)

Heliport approach zone: Slopes eight feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a distance of 4,000 feet along the heliport approach zone centerline.

(9)

Departure zone: Slopes 40 feet outward for each foot upward beginning at the stop end of runway or clearway, for a distance 10,200 feet, to a height of 255 feet above the runway end elevation.
