(A) (1) In order to carry out the provisions of this subchapter, there are created and established certain zones which include all of the land lying within the approach zones, transition zones, horizontal zone and conical zone.
(2) Such areas and zones are shown on the airport zoning map consisting of one sheet, prepared by the state’s Aeronautics Commission and dated 5-1-1968, which is attached to Ord. 2 and made a part of this section by reference.
(B) The various zones are established and defined as follows.
(1) Approach zone. An approach zone is established at each end of all runways on the airport for (non-instrument) landings and takeoffs. The approach zone shall have a width of 250 feet at a distance of 200 feet beyond each end of the runway, widening thereafter uniformly to a width of 2,250 feet at a horizontal distance of 10,200 feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway.
(2) Transition zones. Transition zones are established adjacent to each runway and approach zone as indicated on the zoning map. Transition zones symmetrically located on either side of runways have variable widths as shown on the zoning map. Transition zones extend outward from a line 125 feet on either side of the centerline of the runway, for the length of such runway plus 200 feet on each end, and are parallel and level with such runway centerlines. The transition zones along such runways slope upward and outward one foot vertically for each seven feet horizontally to the point where they intersect the surface of the horizontal zone. Further, transition zones are established adjacent to approach zones for the entire length of the approach zones. These transition zones have variable widths, as shown on the zoning map. Such transition zones flare symmetrically with either side of the runway approach zones from the base of such zones and slope upward and outward at the rate of one foot vertically for each seven feet horizontally to the points where they intersect the surfaces of the horizontal and conical zones.
(3) Horizontal zone. A horizontal zone is established as the area within a circle with its center at the airport reference point and having a radius of 5,000 feet. The horizontal zone does not include the approach zones and the transition zones.
(4) Conical zone. A conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward there from a distance of 3,000 feet. The conical zone does not include the approach zones and transition zones.
