(A) The Airport Overlay Zoning District is composed of several height limitation zones, which include all land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces appurtenant to the Preston City Airport. These zones are shown on supplements to the Official Zoning Map of Franklin County.
(B) An area located in more than one of these zones is considered to be only in the zone with the more restrictive height limitation.
(1) Utility Runway Visual Approach Zone. The inner edge of the Approach Zone coincides with the width of the primary surface and is 250 feet wide. The Approach Zone expands outward uniformly to a width of 1,250 feet at a horizontal distance of 5,000 feet 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.
(3) Horizontal Zones. The Horizontal Zone is established by swinging arcs of 5,000 feet 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 the area that commences at the periphery of the Horizontal Zone and extends outward therefrom a horizontal distance of 4,000 feet.
