89 transitional zones, horizontal zones and conical zones, as they apply to the Concord Regional Airport. Such zones are shown on the Official Concord Regional Airport Hazard Zoning Map which is incorporated with these regulations 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. These zones are 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 outwardly uniformly to a width of 1,500 feet at a horizontal distance of 5,000 feet from the primary surface, Its center line is the continuation of the center line of the runway. (b) Runway Larger Than Utility With a Visibility Minimum Greater Than Three-Fourths 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 center line being the continuation of the center line of the runway. (c) Runway Larger Than Utility With a Visibility Minimum as Law as Three-Fourths Mile Nonprecision Instrument 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 4,000 feet at a horizontal distance of 10,000 feet from the primary surface. Its center line is the continuation of the center line of the runway. (d) 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 width of 16,000 feet at a horizontal distance of 50,000 feet from the primary surface, its center line being the continuation of the center line of the runway. (e) Transitional Zones - These zones are established as the area beneath the transitional surfaces. These surfaces extend outward and upward at 90-degree angles to the runway center line and the runway center line extended a slope of seven feet horizontally for each foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces. Transitional zones for those portions of the precision appr6ach zones, which project through and beyond the limits of the conical surface, extend a distance of 5,000 feet measured horizontally from the edge of the approach zones and at 90~degree angles to the extended runway center line. (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 the transitional zones. (g) 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. The conical zone does not include the precision instrument approach zones and the transitional (2) Airport Zone Hetght Limitations - Except as otherwise provided in these regulations, no structure or tree shall he erected, altered, allowed to grow or be maintained in any of the zones created by these regulations to a height in excess of the applicable height limit herein established for such zone. Such applicable height limitations are hereby established for each of the zones in question, as follows: (a) Runway Larger Than Utility Visual Approach Zone - Slopes 20 feet outward for each foot upward beginning at the end of and at the same
