The following are intended for use with this specific overlay zoning district.
(A) Airport hazard area consists of operation zones, approach zones, turning zones, and transition zones.
(B) Approach zones extend from the end of each operation zone and are centered along the extended runway centerlines. The zones dimensions are:
(1) Instrument runways:
(a) Length and width: The approach zones extend from the operation zone to the limits of the turning zone, measured along the extended runway centerline. The approach zones are 1,000 feet wide at the end nearest the runway and expand uniformly so that at a point on the extended runway centerline 10 miles from the operation zone where it is 16,840 feet wide.
(b) Height limit: The height limit of the approach zones begins at the elevation of the operation zone and rises 1 foot vertically for every 50 feet horizontally (50:1) up to a maximum of 150 feet above the nearest existing or proposed runway end. At 3 miles from such operation zone, the height limit resumes sloping 1 foot vertically for every 50 feet horizontally and continues to the 10-mile limit.
(2) Visual runways:
(a) Length and width: The approach zones extend from the operation zone to the limits of the turning zone, measured along the extended runway centerline. The approach zones are 500 feet wide at the end nearest the runway and expand uniformly so that at a point on the extended runway centerline 3 miles from the operation zone, the approach zone is 3,700 feet wide.
(b) Height limit: The height limit of the approach zones begins at the elevation of the operation zone and rises 1 foot vertically for every 40 feet horizontally (40:1) up to a maximum of 150 feet above the nearest existing or proposed runway end.
(C) Operation zones are longitudinally centered on each existing or proposed runway:
(1) Length:
(a) For existing and proposed paved runways, the operation zones begin and end 200 feet beyond the end of each runway.
(b) For existing and proposed turf runways, the operation zones begin and end at the runway ends.
(c) For existing and proposed instrument runways, the operation zone is 1,000 feet wide, with 500 hundred feet on either side of the runway centerline.
(d) For all other existing and proposed runways, the operation zone is 500 feet wide, with 250 feet on either side of the runway centerline.
(2) Height limit: The height limit of the operation zones is the same as the nearest point on an existing or proposed runway or the surface of the ground, whichever is higher.
(D) Transition zones extend outward at right angles to the runway centerline and upward at a rate of 1 foot vertically for every seven feet horizontally (7:1). The height limit of these zones begins at the height limit of the adjacent operation zones or approach zones. The transition zones end at a height of 150 feet above the nearest existing or proposed runway end.
(E) Turning zones extend three miles as a radius from the corners of the operation zone of each runway and connecting adjacent arcs with tangent lines, excluding any area within the approach zone, operation zone, or transition zone. The height limit of the turning zones is 150 feet above the nearest existing or proposed runway end.
