Section 25.82.060 Height limits.

Except as otherwise provided in this chapter, no structure or tree shall be erected, altered, allowed to grow or be maintained in any airport zone to a height in excess of the height limit herein established for such zone. Such height limitations are computed as follows:

1. Instrument Approach Zone. Height limits are as follows: one foot in height for each fifty feet in horizontal distance beginning at a point two hundred feet from the end of the instrument runway and extending to a distance of ten thousand two hundred feet from the end of the runway; thence one foot in height for each forty feet in horizontal distance to a point fifty thousand two hundred feet from the end of the runway.

2. Noninstrument Approach Zones. Height limits are as follows: one foot in height for each forty feet in horizontal distance beginning at a point two hundred feet from the end of the noninstrument runway and extending to a point ten thousand two hundred feet from the end of the runway.

3. Transition Zones. Height limits are as follows: one foot in height for each seven feet in horizontal distance beginning at a point five hundred feet from the centerline of the instrument and noninstrument runways, measured at right angles to the centerline of the longest dimension of the runway, extending upward to a maximum height of one hundred fifty feet above the established airport elevation which is one thousand ninety-seven feet above mean sea level. In addition to the foregoing, there are established height limits of one foot vertical height for each seven feet 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 and conical surfaces; further, where the instrument approach zone projects through and beyond the conical zone, a height limit of one foot for each seven feet horizontal distance measured from the edges of all approach zones for the entire length of the approach zones and extending upward to the points where they intersect the horizontal and conical surfaces; further, where the instrument approach zone projects through and beyond the conical zone, a height limit of one foot for each seven feet of horizontal distance shall be maintained beginning at the edge of the instrument approach zone and extending a distance of five thousand feet from the edge of the instrument approach zone measured at right angles to the continuation of the aforesaid centerline of the runway.

4. Horizontal Zone. Height limits are as follows: one hundred fifty feet above the airport elevation.

5. Conical Zone. Height limits are as follows: one foot in height for each twenty feet of horizontal distance beginning at the periphery of the horizontal zone and extending for a distance of four thousand feet. (Ord. S-30424, 1976)
