§ 150.17  AIRPORT OVERLAY DISTRICT.
   (A)   In order to carry out the provisions of this subchapter, there is hereby created and established an Airport Overlay (AO) District which includes all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to Dare County Regional Airport.  Such zones are shown on that certain map entitled Dare County Airport (MQI), Manteo, North Carolina, Airport Zoning Map, prepared by Talbert & Bright, Inc., Project No. 2301-0301, dated December 2003, a copy of which is attached to this Ordinance and made a part hereof.  An area located in more than 1 of the following zones is considered to be only in the zone with the more restrictive height limitation.
   (B)   The various zones are hereby established and defined as follows:
      (1)   Utility runway nonprecision instrument approach zone.  The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach zone expands outward uniformly to a width of 2,000 feet at a horizontal distance 5,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.  This zone applies to the Runway 17 and Runway 35 ends.
      (2)   Runway larger than utility with a visibility minimum greater than ¾-mile nonprecision instrument approach zone.  The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach zone expands outward uniformly to a width of 3,500 feet at a horizontal distance of 10,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.  This zone applies to the Runway 23 end.
      (3)   Precision instrument runway approach zone.  The inner edge of this approach zone coincides with the width of the primary surface and is 1,000 feet wide. The approach zone expands outward uniformly to a width of 16,000 feet at a horizontal distance of 50,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.  This zone applies to the Runway 5 end.
      (4)   Transitional zones.  The transitional zones are the areas beneath the transitional surfaces.
      (5)   Horizontal zone.  The horizontal zone is established by swinging arcs of 5,000-feet radii for all runways designated utility or visual and 10,000 feet for all others 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.
      (6)   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 4,000 feet.
