§ 158.03 AIRPORT ZONES.
   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 Garrett County Airport. The zones are shown on the Garrett County Airport Zoning Map consisting of 1 sheet, prepared by United Research Systems, and dated April 2003, which is attached to this chapter 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. The various zones are hereby established and defined as follows:
   (A)   Runway larger than utility visual 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 1,500 feet at a horizontal distance of 5,000 feet from the primary surface. Its centerline is the continuation of the centerline of the runway.
   (B)   Runway larger than utility with a visibility minimum greater than 3/4 mile non-precision 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.
   (C)   Heliport approach zone. The inner edge of this approach zone coincides with the width of the primary surface and is based on present and future heliport operations. The approach zone expands outward uniformly to a width of 500 feet at a horizontal distance of 4,000 feet from the primary surface.
   (D)   Transitional zones. The transitional zones are the areas beneath the transitional surfaces.
   (E)   Heliport transitional zones. These zones extend outward from the sides of the primary surface and the heliport approach zones a horizontal distance of 250 feet from the primary surface centerline and the heliport approach zone centerline.
   (F)   Horizontal zone. The horizontal zone is established by swinging arcs of 10,000 feet 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.
   (G)   Conical zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward there from a horizontal distance of 4,000 feet.
