(A) Established. Except as otherwise provided in this subchapter, no structure or tree shall be erected, altered, allowed to grow or maintained in any zone created by this subchapter to a height in excess of the height limit established in this section for such zone. Such height limitations are established for each of the zones in question as follows:
(1) 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 runway and extending to a point 10,200 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 runways extending 200 feet beyond each end, extending to a height of 150 feet above the airport elevation, which is 912.20 feet above mean sea level. In addition, 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: 150 feet above the airport elevation or a height of 912.20 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 300 feet above the airport elevation.
(B) Excepted height limitations. Nothing in this section shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height up to 30 feet above the surface of the runway.
(C) Multiple limitations. Where an area is covered by more than one height limitation, the more restrictive limitations shall prevail.
