§ 26-621. Height limitations.

(a)

Except as otherwise provided in this division, no structure or tree shall be erected, altered, allowed to grow or maintained in any zone created by this division to a height in excess of the height limit elevation established by this division for such zone.

(b)

The boundary and height limit elevation for each type zone is hereby established as follows:

(1)

Airport approach surface zones.

a.

North approach surface. Beginning at a point 200 feet north of the north end of Runway 1-19, an inclined surface starting at elevation 42.5 feet MSL with a slope of 50:1, 1,000 feet wide, symmetrical about the projected runway centerline and extending a horizontal distance of 10,000 feet from the point of beginning with a width of 4,000 feet symmetrical about the projected runway centerline at the 10,000-foot point. Continuing from the 10,000-foot point, an inclined surface with a slope of 40:1, 4,000 feet wide, symmetrical about the projected runway centerline at the 10,000-foot point and extending a horizontal distance of 40,000 feet from the 10,000-foot point with a width of 16,000 feet, symmetrical about the projected runway centerline at the 40,000-foot point.

b.

South approach surface. Beginning at a point 200 feet south of the south end of Runway 1-19, an inclined surface starting at elevation 36.87 feet MSL with a slope of 50:1, 1,000 feet wide, symmetrical about the projected runway centerline and extending a horizontal distance of 10,000 feet from the point of beginning with a width of 4,000 feet symmetrical about the projected runway centerline at the 10,000-foot point. Continuing from the 10,000-foot point, an inclined surface with a slope of 40:1, 4,000 feet wide, symmetrical about the projected runway centerline at the 10,000-foot point and extending a horizontal distance of 40,000 feet from the 10,000-foot point with a width of 16,000 feet, symmetrical about the projected runway centerline at the 40,000-foot point.

c.

East approach surface. Beginning at a point 200 feet east of the east end of Runway 10-28, an inclined surface starting at elevation 38 feet MSL with a slope of 40:1, 500 feet wide, symmetrical about the projected runway centerline and extending a horizontal distance of 10,000 feet from the point of beginning, with a width of 2,500 feet symmetrical about the projected runway centerline at the 10,000-foot point and an elevation of 288 feet MSL at the 10,000-foot point.

d.

West approach surface. Beginning at a point 200 feet west of the west end of Runway 10-28, an inclined surface starting at elevation 37 feet MSL with a slope of 40:1, 500 feet wide, symmetrical about the projected runway centerline and extending a horizontal distance of 10,000 feet from the point of beginning, with a width of 2,500 feet symmetrical about the projected runway centerline at the 10,000-foot point and an elevation of 287 feet MSL at the 10,000-foot point.

(2)

Transition surface zones. An inclined surface at right angles to the runway centerline and/or the projection thereof extending on a slope of 7:1 from the edge of the landing zone at the elevation of the runway centerline to an intersection with the horizontal surface at elevation 192.5 feet MSL and extending on a slope of 7:1 from the edge of the approach surfaces to an intersection with the horizontal surface at elevation 192.5 feet MSL or the conical surface.

(3)

Horizontal surface zones. A horizontal circular surface at elevation 192.5 feet centered at the established airport reference point with a radius of 10,000 feet.

(4)

Conical surface zones. An inclined conical surface concentric with and adjacent to the perimeter of the horizontal surface with a horizontal width of 5,000 feet and a 20:1 slope from elevation 192.5 feet MSL at the circumference of the horizontal surface to elevation 442.5 feet at the exterior circumference of the conical surface.

(5)

Width of landing zones. The width of the landing zones shall be:

a.

Runway 1-19: 1,000 feet.

b.

Runway 10-28: 500 feet.

(c)

The established airport elevation is hereby declared to be 42.5 feet.

(d)

Notwithstanding any other provision of this division to the contrary, the height limits prescribed by this division shall not establish for any particular parcel of land, at any particular point within such parcel, a height limit of less than 50 feet above the surface elevation of the land at this point.
