17.18.010 Purpose.

A. This zone relates to the property within the boundary of the Chelan Municipal Airport and abutting lands within the city limits and Chelan urban growth area (UGA) designated for future airport or airport-related uses.

B. The primary purposes of the Airport District are:

1. To assure that the property comprising the Chelan Municipal Airport will continue to be used in a manner that is compatible with a general aviation airport and aircraft operations.

2. To establish a framework within which both commercial and recreational aviation and aviation-related activities can prosper.

3. To discourage the siting of incompatible uses within the Airport District.

C. This chapter provides for both aviation-related and compatible commercial and light industrial development within the Airport Zone.

D. Development standards are established to assure the orderly and appropriate use of airport property. These standards identify and protect the operating spaces necessary for aircraft. They also set regulations for commercial and light industrial/manufacturing development that may occur on airport property.

E. This chapter is adopted pursuant to Chapter 14.12 RCW, the “Airport Zoning Act,” Federal Air Regulation Part 77 “Objects Affecting Navigable Airspace” and Federal Aviation Administration Advisory Circular 150/5300-13 “Airport Design,” as now exist or as may be hereafter amended. (Ord. 1533 § 6 (Exh. 21) (part), 2017: Ord. 1075 § 1 (part), 1997).
