The Horizontal Zone is all that land which lies directly under an imaginary horizontal surface 150 feet above the established airport elevation, or a height of 1,521.1 feet above mean sea level, the perimeter of which is constructed by swinging arcs of specified radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by lines tangent to those arcs. The radius of each arc is 6,000 feet for both runways.
