As used in this article, the following terms shall have the meanings respectively ascribed to them, unless the context clearly requires otherwise:
ADMINISTRATOR
The official charged with the enforcement of this article shall be the Zoning Administrator.
AIRPORT
The New Market Airport.
[Amended 9-23-1997 by Ord. No. 97-7]
AIRPORT ELEVATION
The highest point on any usable landing surface expressed in feet above mean sea level.
APPROACH, CLEAR AND TRANSITIONAL ZONES
The airspace zones as set forth in § 165-140 of this article.
APPROACH SLOPE
An imaginary surface, longitudinally centered on the extended runway center line, beginning 100 feet from the end of the runway and extending outward and upward at a fifteen to one (15:1) slope for a distance of 5,000 feet. The inner edge of the "approach slope" is the same width as the primary surface and expands uniformly to a width of 1,200 feet. The geometric design of the "approach slope" coincides with the Commonwealth of Virginia Rule 19 Surfaces in effect on August 1991.
HAZARD TO AIR NAVIGATION
An obstruction determined by the Virginia Department of Aviation or the Federal Aviation Administration to have a substantial adverse effect on the safe and efficient utilization of navigable airspace in the commonwealth.
HEIGHT
For the purpose of determining the height limits in all zones set forth in § 165-141 of this article and shown on the Zoning Map, the datum shall be mean sea level (MSL) elevation unless otherwise specified.
NONCONFORMING USE
Any preexisting structure or object of natural growth which is inconsistent with the provisions of this article or any amendment to this article.
OBSTRUCTION
Any structure, growth or other object, including a mobile object, which exceeds a limiting height or penetrates any surface or zone floor set forth in § 165-141 of this article.
PERMIT
A certification issued by the Zoning Administrator of Shenandoah County allowing a person to begin an activity in accordance with this article.
PERSON
Any individual, firm, partnership, corporation, company, association, joint-stock association or government entity. The term includes a trustee, a receiver, an assignee, or a similar representative of any of them.
PRIMARY SURFACE
A surface, longitudinally centered on a runway. The elevation of any point on the "primary surface" is the same as the elevation of the nearest point on the runway center line.
RUNWAY
A specified area on an airport prepared for landing and takeoff of aircraft.
SIDE SLOPE AREA
An area included in the transitional surface.
STRUCTURE
Any object, including a mobile object, constructed or installed by any person, including but not limited to buildings, towers, cranes, smokestacks, earth formations, towers, poles and electric lines of overhead transmission routes, flag poles and ship masts.
TRANSITIONAL SURFACE
An imaginary surface extending outward and upward at right angles from the edge of the primary surface for a horizontal distance of 1,666.7 feet on an upward slope of five to one (5:1). The "transitional surface" gradually tapers from the 1,666.7 foot mark until it connects with the outermost edge of the approach slope. The side slope area is included in the "transitional surface." The geometric design of the "transitional surface" coincides with the Commonwealth of Virginia Rule 19 Surfaces in effect in August 1991.
VEGETATION
Any object of natural growth.
ZONE
All areas provided for in § 165-140 of this article, generally described in three dimensions by reference to ground elevation, horizontal distances from the runway center line and the primary surface and with the zone floor set at specific vertical limits by the surfaces found in § 165-141 of this article.
