The purpose of this section is to establish regulations for airports and air navigation space.

(Ord. No. 2008-3179, § 1, 12-18-08)

It is the intent of this section to:

A.

Provide appropriate height limitations for structures and trees within proximity to aircraft landing approach areas and major airport maneuvering areas.

B.

Provide specific design standards for airports.

(Ord. No. 2008-3179, § 1, 12-18-08)

These regulations shall apply as hereinafter indicated.

(Ord. No. 2008-3179, § 1, 12-18-08)

Airport zones are hereby created and established in the City of Maryland Heights and shall comprise all of the land lying beneath airport approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces. Except as otherwise provided in this section, no object shall be erected, altered, maintained, planted, or be allowed to grow in any zone to a height in excess of the applicable height limitations herein established for such zone. A tract of land located in more than one of the following zones shall be deemed to be in the zone with the more restrictive height limitation. Other regulations appearing in this section that are inconsistent herewith are superseded to the extent of such inconsistency.

(Ord. No. 2008-3179, § 1, 12-18-08)

The various zones and their height limitations are hereby established and defined as follows:

A.

Utility runway visual approach zone. Shall have a width at its inner edge coinciding with the width of the runway's primary surface, as defined in appendix A.7, definitions relating to air navigation, and expanding outwardly to a width of one thousand two hundred fifty (1,250) feet at a horizontal distance of five thousand (5,000) feet from the primary surface. The centerline of the approach zone shall be established by an imaginary plane sloping twenty (20) feet outward for each foot upward, commencing at the end of and at the same elevation as the primary surface, and extending to a horizontal distance of five thousand (5,000) feet along the extended runway centerline.

B.

Transitional zones. The areas beneath the transitional surfaces. The height limitations shall be established by an imaginary place sloping seven (7) feet onward for each foot upward, commencing at the sides of and at the same elevation as the primary surface and the approach surface, and extending to a height of one hundred fifty (150) feet above the airport elevation. In addition to the foregoing there are established height limits sloping seven (7) feet outward for each foot upward beginning at the sides of and at the same elevation as the approach surface, and extending to where they intersect the conical surface.

C.

Horizontal zones. Established by swinging arcs of five thousand (5,000) 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 transitional zones. The height limitation shall be an imaginary plane lying one hundred fifty (150) feet above the airport elevation.

D.

Conical zone. Established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a horizontal distance of four thousand (4,000) feet. The height limitation shall be established by an imaginary plane sloping twenty (20) feet outward for each foot upward beginning at the periphery of the horizontal zone and at one hundred fifty (150) feet above the airport elevation and extending to a height of three hundred fifty (350) feet above the said airport elevation.

(Ord. No. 2008-3179, § 1, 12-18-08)

A.

Nothing in these regulations shall be construed to prohibit the construction or maintenance of any structure, or growth of any tree not exceeding a height of thirty-five (35) feet above the airport elevation at the base of such structure or tree.

B.

Notwithstanding any other provision, and with the exception of subsection C below, no use may be made of land or water within any zone established by this section in such a manner as to create electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create a bird strike hazard, or otherwise in any way endanger or interfere with the landing, takeoff, or maneuvering of aircraft intending to use the airport.

C.

The regulations prescribed by this section shall not be construed to require the removal, lowering, or other change or alteration of any object not conforming to the regulations as of the effective date of this Code, or otherwise interfere with the continuance of the nonconforming use. Nothing contained herein shall require any change in the construction, alteration, or intended use of any object, the construction or alteration of which was begun prior to the effective date of this chapter, and is diligently prosecuted. Notwithstanding the preceding provision of this paragraph, the owner of any existing nonconforming structure or tree is hereby required to permit the installation, operation, and maintenance thereon of such markers and lights as shall be deemed necessary by the city planner to indicate to the operators of aircraft in the vicinity of the airport the presence of such airport obstruction. Such markers and lights shall be installed, operated, and maintained at the expense of the airport to be protected thereby.

D.

Construction or alteration of structures near airport runways may require Federal Aviation Administration (FAA) review In accordance with Federal Aviation Regulations Part 77, "Objections Affecting Navigable Airspace."

(Ord. No. 2008-3179, § 1, 12-18-08)

A.
