Approach/Departure Surface: A surface longitudinally centered on the extended runway center line. The inner edge of the approach/departure surface is the same width as the primary surface (500-feet), expanding uniformly to a width of 3,500 feet.
A. The south approach/departure surface (Runway 2), starts at the south end of the runway extending 1400 feet horizontally then from the corners of the 500 foot primary surface then extending 10000 feet to a final width of 3500 feet at a slope of 40:1.
B. The north approach departure surface (Runway 20), starts at the northern corners of the primary surface and extends 5,000 feet northward to a final width of 1,500 feet, at a slope of 20-feet outward for each foot upward.
Conical Surface: A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to 1 for a horizontal distance of 4,000-feet.
Horizontal Surface: A horizontal plane 150-feet above the established airport elevation, the perimeter of which is constructed by swinging arcs a radius of 10,000-feet from the center of each end of the primary surface of each runway and connecting the adjacent arcs by lines tangent to those arcs.
Notification Zone: A surface extending from the nearest point of the runway out 20,000 feet at a slope of 100 to 1 which requires notification to the F.A.A. via Form 7460-1 with one copy provided to the airport manager.
Primary Surface: A surface longitudinally centered on a runway, extending 500-feet each side of centerline pursuant to Part 77, Federal Aviation Regulations (FAR), and 1400 feet beyond the south end and 200 feet beyond the north end. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.

Structures: Regardless of the underlying zone district, any structure within the airport overlay zone which is allowed as a use by right shall require application for a zoning certificate prior to the onset of construction.
Lighting: No new or expanded industrial, commercial, recreational or residential use shall project lighting directly onto an existing runway, taxiway or approach/departure surface except where necessary for safe air travel. Lighting for these uses shall incorporate shielding to reflect light away from airport approach/departure surfaces, and shall not imitate airport lighting.
Communications Facilities and Electrical Interference: No use shall cause or create electrical interference with navigational signals or radio communications between an airport and aircraft.
