(A) Airspace zones. In order to carry out the purpose of this subchapter, as set forth in § 152.20 above, the following airspace zones are hereby established: Primary Zone; Horizontal Zone; Approach Zone; Conical Zone; and Transitional Zone, and whose locations and dimensions are as follows.
(1) Primary zone. All that land which lies directly under an imaginary primary surface longitudinally centered on a runway and extending 200 feet beyond each end of runway 07-25. The elevation of any point on the primary surface is the same as the elevation of the nearest point of the runway centerline. The width of the primary surface is 500 feet for runway 07-25.
(2) Horizontal zone. All that land which lies directly under an imaginary horizontal surface 150 feet above the established airport elevation, or a height of 3,460 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 10,000 feet for runway 07-25.
(3) Conical zone. All that land which lies directly under an imaginary conical surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to one for a horizontal distance of 4,000 feet as measured radially outward from the periphery of the horizontal surface.
(4) Approach zone. All that land which lies directly under an imaginary approach surface longitudinally centered on the extended centerline at each end of a runway. The approach surface is 500 feet in width, and is the same elevation as, and coincides with, the end of the primary surface. The approach surface inclines outward and upward at a slope of 34 to one for runway 07-25. The approach surface expands uniformly to a width of 3,500 feet for runway 07-25. The approach surface extends for a horizontal distance of 10,000 feet for runway 07-25.
(5) Transitional zone. All that land which lies directly under an imaginary surface extending outward and upward at right angles to the runway centerline and extended at a slope of seven to one from the sides of the primary surfaces and from the sides of the approach surfaces until they intersect the horizontal surface or the conical surface.
(B) Height restrictions.
(1) Except as otherwise provided in this subchapter, and except as necessary and incidental to airport operations, no structure or tree shall be constructed, altered, maintained, or allowed to grow in any airspace zone created in division (A) above so as to project above any of the imaginary airspace surfaces described in said division (A) above.
(2) Where an area is covered by more than one height limitation, the more restrictive limitations shall prevail. Nothing in this subchapter shall be construed as prohibiting the growth, construction, alteration, or maintenance of any tree or structure so long as the tree or structure does not project above the imaginary airspace surfaces described in said division (A) above. However, this condition or interpretation of the severability clause shall be in no way foreclose the public right to acquire easements, through purchase or condemnation, over such area when necessary.
