§ 3-59. Height limitations.

Except as otherwise provided in this division, no structure or tree shall be erected, altered, allowed to grow, or maintained in any zone created by this division to a height in excess of the height limit herein established for such zone. Such height limitations are hereby established for each of the zones in question as follows:

(1)

Precision instrument runway approach zone. Slopes upward one foot in height for each fifty (50) feet in horizontal distance beginning at a point two hundred (200) feet from and at the center line elevation of the end of the instrument runway and extending to a distance of ten thousand two hundred (10,200) feet from the end of the runway; thence one foot in height for each forty (40) feet in horizontal distance to a point fifty thousand two hundred (50,200) feet from the end of the runway and at the same elevation as the primary surface;

(2)

Nonprecision instrument runway approach zones. Slopes upward one foot in height for each thirty-four (34) feet in horizontal distance beginning at a point two hundred (200) feet from and at the center line elevation of the end of the noninstrument runway and extending to a point ten thousand two hundred (10,200) feet from the end of the runway;

(3)

Transitional zones. Slopes upward and outward one foot in height for each seven (7) feet in horizontal distance beginning at any point two hundred fifty (250) feet normal to and at the elevation of the center line of nonprecision instrument runways, extending two hundred (200) feet beyond each end thereof, and five hundred (500) feet normal to and at the elevation of the center line of the instrument runway, extending two hundred (200) feet beyond each end thereof, extending to a height of one hundred fifty (150) feet above the airport elevation which is one hundred eight (108) feet above mean sea level. In addition to the foregoing, there are established height limits of one foot vertical height for each seven (7) 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. Further, where the instrument approach zone projects through and beyond the conical zone, a height limit of one foot for each seven (7) feet of horizontal distance shall be maintained beginning at the edge of the instrument approach zone and extending to a horizontal distance of five thousand (5,000) feet from the edge of the instrument approach zone measured normal to the center line of the runway extended;

(4)

Horizontal zone. One hundred fifty (150) feet above the airport elevation or a height of two hundred fifty-eight (258) feet above mean sea level;

(5)

Conical zone. Slopes upward and outward one foot in height for each twenty (20) feet of horizontal distance beginning at the periphery of the horizontal zone, extending to a height of three hundred fifty (350) feet above the airport elevation; and

(6)

Excepted height limitations. Nothing in this division shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height up to thirty (30) feet above the surface of the land.

Where an area is covered by more than one height limitation, the more restrictive limitations shall prevail.
