Sec. 27-264.  Zone descriptions - Airport Overlay.


(a)   An “operation zone” shall be longitudinally centered on each existing or proposed runway.  Such operation zone extends two hundred (200) feet beyond the end of each runway.  For paved runways, the runway end shall be determined by the end of the runway hard surfacing and shall begin and end at the same points as the runway begins and ends for turf runways.  The operation zones are one thousand (1,000) feet wide with five hundred (500) feet on either side of the instrument runway centerline and are five hundred (500) feet wide with two hundred fifty (250) feet on either side of the runway centerline for all other runways.


(b)   An "approach zone" shall extend from the end of each operation zone and shall be centered along the extended runway centerlines.  Instrument runway approach zones extend ten miles from the operation zone, measured along the extended runway centerline.  The approach zone is one thousand (1,000) feet wide at the end of the zone nearest the runway which is adjacent to the operation zone and expands uniformly to sixteen thousand eight hundred forty (16,840) feet wide at the farthest end of the zone which is ten miles (10) from the operation zone.


(c)   The "turning zones" shall be located at a distance of three miles (3) radius from the corners of the operation zone of each runway and connecting adjacent arcs with tangent lines, excluding any area within the operation zone, approach zone, or transition zone.


(d)   The “transition zones” shall extend outward at a right angle to the runway centerline and upward at a rate of one foot vertically for every seven feet horizontally (7:1) and ends at a height of one hundred fifty (150) feet above the highest elevation on the existing or proposed runway.
