A. Except as otherwise provided in this chapter, no structure or tree shall be erected, altered, allowed to grow, or maintained in any zone created by this chapter to a height in excess of the height limitation established for such zone. Such height limitations are established for each of the zones as follows:
1. Precision Instrument Approach Zone: One foot (1') in height for each fifty feet (50') in horizontal distance beginning at a point two hundred feet (200') from and at the centerline elevation of the planned end of the precision instrument runway and extending to a distance of ten thousand two hundred feet (10,200') from the end of the runway; thence one foot (1') in height for each forty feet (40') in horizontal distance to a point fifty thousand two hundred feet (50,200') from the planned end of the runway.
2. Utility Approach Zones: One foot (1') in height for each twenty feet (20') in horizontal distance beginning at a point two hundred feet (200') from and at the centerline elevation of the planned end of the utility runway and extending to a point five thousand two hundred feet (5,200') from the planned end of the runway.
3. Transition Zones: One foot (1') in height for each seven feet (7') in horizontal distance beginning at any point one hundred twenty five feet (125') normal to and at the elevation of the centerline of utility runways, extending two hundred feet (200') beyond each end thereof, and five hundred feet (500') normal to and at the elevation of the centerline of the precision instrument runway, extending two hundred feet (200') beyond each end thereof, extending to a height of one hundred fifty feet (150') above the airport elevation which is three thousand eight hundred seventy three feet (3,873') above mean sea level. In addition to the foregoing there are established height limits of one foot (1') vertical height for each seven feet (7') horizontal distance measured from the edges of all approach zones for the entire length of the approach zones and extending upward and outward to the points where they intersect the horizontal or conical surfaces. Further where the precision instrument approach zone projects through and beyond the conical zone, a height limit of one foot (1') for each seven feet (7') of horizontal distance shall be maintained beginning at the edge of the instrument approach zone measured normal to the centerline of the runway extended.
4. Horizontal Zone: One hundred fifty feet (150') above the airport elevation or a height of four thousand twenty three feet (4,023') above mean sea level.
5. Conical Zone: One foot (1') in height for each twenty feet (20') of horizontal distance beginning at the periphery of the horizontal zone, extending to a height of three hundred fifty feet (350') above the airport elevation.
B. Nothing in this chapter shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height up to fifty feet (50') above the surface of the land. (Ord. 2359, 5-20-1985)
