In order to carry out the provision of this chapter, there are hereby created and established certain zones which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to the Council airport. Such zones are shown on the Council airport zoning map consisting of one sheet, prepared by the airport commission, which is attached to the ordinance codified herein and made a part hereof. An area located in more than one of the following zones is considered to be only in the zone with the more restrictive height limitation. The various zones are hereby established and defined as follows:
A. Utility Runway Visual Approach Zone: The inner edge of the utility runway visual approach zone coincides with the width of the primary surface and is two hundred fifty feet (250'). The approach zone expands outward uniformly to a width of one thousand two hundred fifty feet (1,250') at a horizontal distance of five thousand feet (5,000') from the primary surface. Its centerline is the continuation of the centerline of the runway.
B. Transitional Zones: The transitional zones are the areas beneath the transitional surfaces.
C. Horizontal Zone: The horizontal zone is established by swinging arcs of five thousand feet (5,000') radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach and transitional zones.
D. Conical Zone: The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a horizontal distance of four thousand feet (4,000'). (Ord. 355B, 6-8-1999)
