protection zone 1 and extends out 2,800 feet, The zone measures 1,010 feet across, 505 feet on either side of the runway centerline. c. Inner Turning Zone 3. A fan shaped area extending beyond the center lines of runways 11, 29, 07, and 25 as depicted on map "B" (shaded area #3). This zone begins at the primary surface, 200 feet from the end of the runway centerline and extends out with a 60-degree radius arc on either side of the runway centerline to 4,500 feet and connects to the centerline of the inner safety zone with sweeping arcs. d. Outer Safety Zone 4. Area extending beyond the centerlines of runways 11, 29, 07, and 25 as depicted on map "B" (shaded area #4). This zone begins at the end of the inner safety zone and extends out 3,000 feet. The zone measures 1,000 feet across, 500 feet on either side of the runway centerline. e. Sideline Zone 5. An area adjacent to runways 11, 29, 07, and 25 as depicted on map "B" (shaded area #5). This zone begins from the outer boundaries of the primary surface, and extends out 1,000 feet perpendicular to the primary surface and connects to the 60-degree sector of the inner turning zone. f. Airport Operations Zone 6. This zone is depicted on map "B" (shaded area #6) and begins from the outer boundaries of the sideline zone and extends out 5,000 feet perpendicular to the primary surface and connects to the 60-degree sector of the inner turning zone. (Ord. 2020-XX; Ord. 2007-22, 2007; Ord. 2001-10 (part), 2001) 17.58.040B Airport overlay zoning district: Easton State, Cle Elum Municipal, and DeVere Field. In order to carry out the provisions of this chapter, there is hereby created an airport overlay zoning district that is composed of the following surface and safety zones for the Easton State, Cle Elum Municipal and DeVere Field. The zones cover a geographic area that is affected by airport activities and are defined on the basis of factors including, but not limited to, aircraft noise, aircraft flight patterns, airport safety zones, local circulation patterns and area development patterns. The surface and safety zones are overlaid on top of the existing underlying zoning, which remains in full force and effect. Where the requirements imposed by the surface and safety zones conflict with the requirements of the underlying zoning, the more restrictive requirement shall be enforced. With the exception of those necessary and incidental to airport operations, no uses shall be permitted that allow buildings, structures, vegetation or other development that penetrates the imaginary air surfaces described below. 1. Surface Zones. In order to carry out the provisions of this chapter, there are created and established certain surface zones which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to each airport . Such zones are shown on overlay zoning map "A" for each airport, as amended. Within each of the surface zones there are hereby established certain height restrictions for structures and trees. The surface zones are established and defined as follows: Approach Zone. A surface longitudinally centered on the extended runway centerline. Its centerline is the continuation of the runway centerline as depicted on map "A". Visual Runways. The 250-foot or 500-foot inner edge coincides with the width of the primary surface and slopes 20 feet outward for each one foot upward beginning at the end of and at the same elevation as the primary surface and expands to a width of 1,250 feet or 1,500 feet at a horizontal distance of 5,000 feet along the extended runway centerline. The variable surface widths noted in this section are determined based on “Utility” or “Larger than Utility” FAR Part 77 designations assigned to each runway.
