In order to carry out the provisions of this chapter, there are created and established certain zones which include all of the land lying within the noninstrument approach zones, transition zones, horizontal zone and conical zone, Such areas and zones are shown on the Clovis Municipal Airport zoning map consisting of one sheet, prepared by Lydick Engineers and Surveyors, and dated September 1, 1970, which is attached to the ordinance codified in this chapter and is made a part hereof as though set forth in this chapter. The various zones are established and defined as follows:

A. Noninstrument Approach Zone. A noninstrument approach zone is established at each end of all runways for noninstrument landings and takeoffs. The noninstrument approach zone shall have a width of five hundred feet at a distance of two hundred feet beyond each end of the runways, widening thereafter uniformly to a width of two thousand five hundred feet at a distance of ten thousand two hundred feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway.

B. 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 two hundred fifty feet on either side of the centerline of the runways, for the length of such runways plus two hundred 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 the noninstrument approach zones for the entire length of the approach zones. These transition zones have variable width, 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.

C. 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 seven thousand feet. The horizontal zone does not include noninstrument approach zones and the transition zones.

D. Conical zone. A conical zone is established as the area that commences as the periphery of the horizontal zone and extends outward therefrom a distance of five thousand feet. The conical zone does not include the transition zones. (Ord. 1022 § 3, 1974).
