§ 45-3102. Definitions.

As used in this article, the following terms shall have the meanings respectively ascribed to them, unless the context clearly requires otherwise:

(1)

Administrator: The zoning administrator of the City of Newport News.

(2)

Airport: Newport News/Williamsburg International Airport.

(3)

Airport elevation: Forty-three (43) feet above mean sea level.

(4)

Approach surface: A surface longitudinally centered on the extended runway centerline, extending outward and upward from the end of the primary surface, and at the same slope as the approach zone height limitation slope set forth in section 45-3104 of this chapter. In plan view the perimeter of the approach surface coincides with the perimeter of the approach zone.

(5)

Approach, transitional, horizontal, and conical zones: The airspace zones as set forth in section 45-3103 of this chapter.

(6)

Conical surface: A surface extending outward and upward from the periphery of the horizontal surface at a slope of twenty (20) to one (1) for a horizontal distance of four thousand (4,000) feet.

(7)

Hazard to air navigation: An obstruction determined to have a substantial adverse effect on the safe and efficient utilization of navigable airspace.

(8)

Height: For the purpose of determining the height limits in all zones set forth in this chapter and shown on the zoning map, the datum shall be mean sea level elevation unless otherwise specified.

(9)

Horizontal surface: A horizontal plane one hundred and fifty (150) feet above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.

(10)

Larger than utility runway: A runway that is constructed for and intended to be used by propeller-driven aircraft of greater than twelve thousand and five hundred (12,500) pounds maximum gross weight and jet-powered aircraft. The width of this runway surface is set forth in section 45-3103.

(11)

Nonconforming use or object: Any preexisting structure or object of natural growth which is inconsistent with the provisions of, or any amendment to, this chapter.

(12)

Nonprecision instrument runway: A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in nonprecision instrument approach procedure has been approved or planned.

(13)

Obstruction: Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in section 45-3103.

(14)

Permit: A document issued by the City of Newport News allowing a person to begin an activity which may result in any structure or vegetation exceeding the height limitations provided for in section 45-3107.

(15)

Person: Any individual, firm, partnership, corporation, company, association, joint stock association, or governmental entity. The term includes a trustee, a receiver, an assignee, or a similar representative of any of them.

(16)

Precision instrument runway: A runway having an existing instrument approach procedure utilizing an instrument landing system (ILS or MLS) or a precision approach radar (PAR). It also means a runway for which a precision approach system is planned and is so indicated on an approved airport layout plan.

(17)

Primary surface: A surface, with a specified width as provided in section 45-3103 of this chapter, longitudinally centered on a runway. When the runway has a specifically prepared hard surface, the primary surface extends two hundred (200) feet beyond each end of that runway. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline. The width of the primary surface is set forth in section 45-3103.

(18)

Runway: A specified area on an airport prepared for landing and takeoff of aircraft along its length.

(19)

Structure: Any object, including a mobile object, constructed or installed by any person, including but not limited to buildings, cranes, smokestacks, earth formations, towers, poles, and overhead transmission lines.

(20)

Transitional surfaces: These surfaces extend outward at ninety-degree angles to the runway centerline and the runway centerline extended at a slope of seven (7) feet horizontally for each one (1) foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces. Transitional surfaces for those portions of the precision approach surfaces, which project through and beyond the limits of the conical surface, extend a distance of five thousand (5,000) feet, measured horizontally from the edge of the approach surface and at ninety-degree angles to the extended runway centerline.

(21)

Tree: Any object of natural growth.

(22)

Visual runway: A runway intended solely for the operation of aircraft using visual approach procedures.

(23)

Zone: All areas provided for in section 45-3103 of this article, generally described in three (3) dimensions by reference to ground elevation, vertical distances from the ground elevation, horizontal distances from the runway centerline and the primary and horizontal surfaces, with the zone floor set at specific vertical limits by the surfaces found in section 45-3104.
