12-8-3: AIRPORT ZONES:
   A.   Zones Created: In order to carry out the provisions 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 Seminole regional airport. Such zones are shown on the Seminole regional airport layout map on file in the office of the director of public works 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. (2000 Code § 12-803; amd. Ord. 1075, 3-11-2008, eff. 4-10-2008)
   B.   Zones Defined: The various zones are hereby established and defined as follows:
      1.   Utility Runway Visual Approach Zone: The inner edge of this approach zone coincides with the width of the primary surface and is two hundred fifty feet (250') wide. 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.
      2.   Transitional Zones: The transitional zones are the areas beneath the transitional surfaces. These zones are located adjacent to and at the sides of the primary surface and approach zones and are directly under the transitional surfaces. These surfaces extend outward and upward at ninety degree (90°) angles to the runway centerline (and extended runway centerline), at a slope of seven feet (7') horizontal for each one foot (1') vertical from the sides of the primary surface and approach zones to the point where the transitional (conical) surface intersects with horizontal surface.
      3.   Horizontal Zone: The horizontal zone is established by swinging arcs of five thousand foot (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.
      4.   Conical Zone: The conical zone is established as the area that commences at the periphery (the conical zone is adjacent to the horizontal zone and directly under the conical surface) of the horizontal zone and extends outward therefrom a horizontal distance of four thousand feet (4,000').
