The airport enterprise district (AE) is established to provide lands for and encourage the development of well-planned and designed technological-industrial parks which would accommodate certain industrial, technological, professional offices, and other similar activities that require support by an airport facility for shipping, education, communication, research, or other reasons. Because of the type of operation and high development standards employed, these parks may be adjacent to residential districts, if they are provided with access to arterial or collector streets and shall not be materially detrimental to the health, safety, and welfare of such residential districts. This zone is also intended to accommodate certain commercial activities such as commercial parking lots, automobile rental facilities, hotels, and restaurants that support air and business travelers.
The boundaries of any airport enterprise district shall be established by the town council. Changes in the size of the airport enterprise district are reviewed through the land use district change process in Chapter 18.95 WMC. Generally, an airport enterprise district shall be located adjacent to an aviation facility.
(Ord. 834, 2022)
Aviation-related manufacturing and distribution uses that meet the following performance standards as determined by the airport manager shall be allowed in the AE district, provided:

(b) 
The activity does not emit smoke, fly ash, dust, vapor, gases, or other forms of air pollution that would interfere with the safe operation of aircraft or that may conflict with present or planned operations of the airport;
(c)

(e) 
The activity does not create electronic interference with communications among aviators and ground control personnel.
