§ 33-376. Establishment of zone classification districts for airport zoning area.

For the purpose of this article all of the airport zoning area for Homestead General Aviation Airport, as the same is created, established and described hereinbefore, is hereby divided into zone classification districts as follows:

(1)

L or Landing districts. A "landing district" is established for each instrument runway for instrument landings and take-offs and for each non-instrument runway for non-instrument landings and take-offs.

A landing district for an instrument runway shall have a uniform width of one thousand (1,000) feet, shall extend for the full length of such instrument runway plus a distance of two hundred (200) feet beyond each end thereof and shall include such runway and be symmetrical about the centerline thereof.

A landing district for non-instrument runway shall have a uniform width of five hundred (500) feet, shall extend for the full length of such non-instrument runway plus a distance of two hundred (200) feet beyond each end thereof and shall include such runway and be symmetrical about the centerline thereof.

(2)

IA or Instrument approach districts. An "instrument approach district" is established for each end of each instrument runway for instrument landings and take-offs and it is further established that each such instrument approach district shall embrace and include all of the land and water area lying vertically beneath an imaginary inclined surface which shall hereafter, for the purposes of this article, be referred to and described as the instrument approach surface.

The instrument approach surface shall begin, and shall have a base one thousand (1,000) feet wide, at a distance of two hundred (200) feet beyond the end of the runway, widening thereafter uniformly to a width of sixteen thousand (16,000) feet at a horizontal distance of fifty thousand two hundred (50,200) feet beyond the end of the runway, the centerline of this surface being the continuation of the centerline of the runway. The instrument approach surface shall extend outward and upward from its base, the elevation of which shall be the same as that of the runway end adjacent thereto, with a slope of one (1) foot vertically to fifty (50) feet horizontally for the first ten thousand (10,000) feet of its length and thence with a slope of one (1) foot vertically to forty (40) feet horizontally for the remainder.

(3)

NA or Non-instrument approach districts. A "non-instrument approach district" is established for each end of each non-instrument runway for non-instrument landings and take-offs and it is further established that each such non-instrument approach district shall embrace and include all of the land and water area lying vertically beneath an imaginary inclined surface which shall hereafter, for the purposes of this article be referred to and described as the non-instrument approach surface.

The non-instrument approach surface shall begin, and shall have a base five hundred (500) feet wide, at a distance of two hundred (200) feet beyond the end of the runway, widening thereafter uniformly to a width of two thousand five hundred (2,500) feet at a horizontal distance of ten thousand two hundred (10,200) feet beyond the end of the runway, the centerline of this surface being the continuation of the centerline of the runway. The non-instrument approach surface shall extend outward and upward from its base, the elevation of which shall be the same as that of the runway end adjacent thereto, with a slope of one (1) foot vertically to forty (40) feet horizontally for its entire length.

(4)

TR or Transition districts. "Transition districts" are hereby established adjacent to each landing, instrument approach and non-instrument approach district.

Transition districts adjacent to runways embrace and include all of the land and water area lying vertically beneath an imaginary inclined surface symmetrically located on each side of each runway. For instrument runways such imaginary inclined surfaces extend outward from lines parallel to and five hundred (500) feet on either side of the centerline of the runway, upward with a slope of one (1) foot vertically to seven (7) feet horizontally and terminating at an elevation one hundred fifty (150) feet above the hereinbefore established airport elevation. For non-instrument runways such imaginary inclined surfaces extend outward from lines parallel to and two hundred fifty (250) feet on either side of the centerline of the runway, upward with a slope of one (1) foot vertically to seven (7) feet horizontally and terminating at an elevation one hundred fifty (150) feet above the hereinbefore established airport elevation.

Transition districts adjacent to non-instrument approach districts embrace and include all of the land and water area lying vertically beneath imaginary inclined surfaces which extend outward and upward from the long sides of the non-instrument approach surfaces, as hereinbefore described, with a slope of one (1) foot vertically to seven (7) feet horizontally terminating at an elevation one hundred fifty (150) feet above the hereinbefore established airport elevation.

Transition districts adjacent to instrument approach districts embrace and include all of the land and water area lying vertically beneath imaginary inclined surfaces which extend outward and upward from the long sides of the instrument approach surfaces as hereinbefore described, with a slope of one (1) foot vertically to seven (7) feet horizontally.

Within horizontal districts, which are hereafter established and described, this imaginary inclined plane shall terminate when it reaches an elevation one hundred fifty (150) feet above the hereinbefore established airport elevation. Within conical districts, which are also hereafter established and described, this imaginary inclined surface shall terminate in its intersection with the conical surface which, for the purposes of this article is described hereinbelow. Outward from the limits of such conical surface, this imaginary inclined surface shall terminate five thousand (5,000) feet from the long sides of the hereinbefore described instrument approach surfaces, such five thousand (5,000) feet being measured horizontally and at right angles to the continuation of the centerline of the runway.

For the purposes of this article, the horizontal surface is established as a horizontal circular surface which has a radius of eleven thousand five hundred (11,500) feet centered vertically above the airport reference point at an elevation one hundred fifty (150) feet above the heretofore established airport elevation.

For the purposes of this article, the conical surface is established as the outer surface of right angled section of an inverted cone, the horizontal circular base of which has a radius of eleven thousand five hundred (11,500) feet centered vertically above the airport reference point at an elevation one hundred fifty (150) feet above the heretofore established airport elevation and the horizontal circular top of which has a radius of eighteen thousand five hundred (18,500) feet at an elevation five hundred (500) feet above the hereinbefore established airport elevation.

(5)

T or Horizontal districts. A "horizontal district" is established as the area within a circle having its center at the airport reference point and eleven thousand five hundred (11,500) feet as its radius. The horizontal district does not include the landing, instrument approach, non-instrument approach and transition districts.

(6)

TI or Conical district. A "conical district" is established commencing at the periphery of the horizontal district and extending to a periphery eighteen thousand five hundred (18,500) feet from the airport reference point. The conical district does not include the instrument approach, non-instrument approach and transition districts.

(7)

NZ or Non-zoned districts. Those portions of the airport zoning area not embraced and included in landing, instrument approach, non-instrument approach, transition, horizontal and conical districts, as the same are established and described elsewhere herein, are hereby designated as non-zoned districts.
