(A) Except as otherwise provided in this article, no structure or tree shall be erected, altered, allowed to grow, or maintained in any zone created by this article to a height in excess of the height limit herein established for such zone. Such height limitations are computed from the established airport elevation and are hereby established for each of the zones in question as follows:
(1) Noninstrument approach zones. One foot in height for each 20 feet in horizontal distance beginning at a point 200 feet from and at the elevation of the end of the noninstrument runway and extending to a point 10,000 feet from the end of the runway;
(2) Transition zones. One foot in height for each seven feet in horizontal distance beginning at any point 125 feet normal to and at the elevation of the centerline of noninstrument runways extending 200 feet beyond each end thereof, extending to a height 150 feet above the airport elevation or 1,624 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 or conical surfaces;
(3) Horizontal zone. One hundred fifty feet above the airport elevation or a height of 1,624 feet above mean sea level; and
(4) Conical zone. One foot in height for each 20 feet of horizontal distance beginning at the periphery of the horizontal zone, extending to a height of 1,824 feet mean sea level.
(B) Where an area is covered by more than one height limitation, the more restrictive limitation shall prevail.
(C) Nothing in this article shall be construed as prohibiting the growth, construction, or maintenance of any tree or structure to a height up to 50 feet above the surface of the land.
