The purpose of the Airport Development (AD) Zone is to allow for development compatible with ongoing airport use consistent with the most recently adopted Deschutes County Year Comprehensive Plan and the most recently approved Bend Airport Master Plan, while providing for public review of proposed development likely to have significant impact on surrounding lands. The AD Zone is composed of three separate zoning districts, each with its own set of allowed uses and distinct regulations, as further set forth in DCC 18.76.

The following definitions apply only to Chapter 18.76.

"Air Traffic Control Tower" means a terminal facility which, through the use of air/ground communications, visual signaling, and other devices, provides air traffic control services to airborne aircraft operating in the vicinity of an airport and to aircraft operating on the airport movement area.

“Customary and usual aviation-related activities” include, but are not limited to, takeoffs, landings, aircraft hangars, tiedowns, construction and maintenance of airport facilities, fixed-base operator facilities, a dwelling unit for an airport caretaker or security officer, and other activities incidental to the normal operation of an airport. Residential, commercial, industrial, manufacturing; and other uses, except as provided in this rule, are not customary and usual aviation-related activities and may only be authorized pursuant to OAR 660-013-0110. “Fixed-base operator or FBO” means a commercial business granted the right by the airport sponsor to operate on an airport and provide aeronautical services such as fueling, hangaring, tie-down and parking, aircraft rental, aircraft maintenance, flight instruction, etc. “Hangar” means an airport structure intended for the following uses:

1. Storage of active aircraft.
2. Shelter for maintenance, repair, or refurbishment of aircraft, but not the indefinite storage of nonoperational aircraft.
3. Construction of amateur-built or kit-built aircraft
4. Storage of aircraft handling equipment, e.g., tow bar, glider tow equipment, workbenches, and tools and materials used to service, maintain, repair or outfit aircraft: items related to ancillary or incidental uses that do not affect the hangars' primary use.
5. Storage of materials related to an aeronautical activity, e.g., balloon and skydiving equipment, office equipment, teaching tools, and materials related to ancillary or incidental uses that do not affect the hangars’ primary use; storage of non-aeronautical items that do not interfere with the primary aeronautical purpose of the hangar (for example, televisions, furniture).
6. A vehicle parked at the hangar while the aircraft usually stored in that hangar is flying, subject to local airport rules and regulations.

8. The use shall make the most effective use reasonably possible of the site topography, existing landscaping and building placement so as to preserve existing trees and natural features, preserve vistas and other views from public ways, minimize visibility of parking, loading, and storage areas from public ways and neighboring residential uses, and minimize intrusion into the character of existing developments and land uses in the immediate vicinity of the proposed use.
