§ 8-110. ZONES ESTABLISHED.
   (A)   In order to carry out the provisions of this article, there are hereby created and established certain zones, which include all of the land lying within the instrument approach zones, noninstrument approach zones, transition zones, horizontal zone, and conical zone. Such areas and zones are shown on the Alva Regional Airport Zoning Map consisting of one sheet, prepared by Myers Engineering, and dated November 8, 1995, which is attached to the ordinance from which this article is derived and made a part hereof.
   (B)   The various zones are hereby established and defined as follows.
      (1)    Noninstrument approach zone. A noninstrument approach zone is established at each end of all noninstrument runways on Alva Regional Airport for noninstrument landings and takeoffs. The noninstrument approach zone shall have a width of 500 feet at a distance of 200 feet beyond each end of the runway, widening thereafter uniformly to a width of 3,500 feet at a distance of 10,000 feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway.
      (2)   Transition zones. Transition zones are hereby established adjacent to each instrument and noninstrument 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 noninstrument runways 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 noninstrument 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 hereby established as the area within a circle with its center at the airport reference point and having a radius of 10,000 feet. The horizontal zone does not include the noninstrument approach zones and the transition zones.
      (4)   Conical zone. A conical zone is hereby established commencing at the periphery of the horizontal zone and extends outward therefrom a distance of 4,000 feet. The conical zone does not include the noninstrument approach zones and transition zones.
