A. There shall be, and hereby is, created a special district to be known as the airport service district. This district shall be subdivided into the following eight subcategories consistent with the Aircraft Accident Safety Zone Diagram contained in Appendix Chapter A of the document Airports and Compatible Land Use, Volume 1, published by the Washington State Department of Transportation, Aviation Division (Appendix Chapter I):

1. ASD-0 – Identified as the “primary surface” in said Aircraft Accident Safety Zone Diagram;

2. ASD-1 – Identified as the “runway protection zone” in said diagram;

3. ASD-2 – Identified as the “inner safety zone” in said diagram;

4. ASD-3 – Identified as the “inner turning zone” in said diagram; provided, this zone shall be further subdivided into west and east categories;

5. ASD-4 – Identified as the “outer safety zone” in said diagram;

6. ASD-5 – Identified as the “sideline safety zone” in said diagram;

7. ASD-6 – Identified as the “traffic pattern zone” in said diagram; provided, this zone shall be further subdivided into west and east categories; and

8. ASD-7 – Identified as the “65 ldn noise contour” in the adopted airport master plan.

B. The specific subcategories of ASD zones one through six identified in subsection (A) of this section shall be delineated as depicted on the following map:

[Ord. 750B § 7, 2003; Ord. 720B § 1, 2002.]

17.30.020 ASD compatible land use chart.

The following chart shall be used to determine whether a land use or development proposal within the ASD is permitted, conditional, or not permitted. Where a conflict may exist between the following chart and the regular land use chart (CMC 17.78.020), the more restrictive requirement shall govern and prevail in the ASD; provided, any use or development upon airport property which is approved by the airport board, and the FAA, if required, shall become a permitted use:

17.30.030 Height restriction.

A. There is established a height restriction line within the ASD zone. No structure shall be erected within the ASD zone that exceeds the elevation of the height restriction line at the location of the structure.

B. The height restriction line shall occur from the edge of the paved runway (not taxiway) surface on all sides, extending outward from the runway at a ratio of one foot vertically for each 34 feet horizontally above and within ASD zones 0, 1, 2 and 3, and one foot vertically for each 20 feet horizontally above and within ASD zones 4, 5 and 6. Such a height limitation shall be depicted on the ASD zone map, expressed in NGVD vertical datum, and shall be interpolated between specified locations.

C. Any development proposal which is not located upon property governed by the Chehalis-Centralia airport board and exceeds said height restriction shall be reviewed by the board prior to consideration of a variance by the hearing examiner. Failure of the board to submit comments to the examiner shall not invalidate any decision made by the city. [Ord. 750B § 9, 2003; Ord. 720B § 1, 2002.]

Such an approval by the board shall constitute a determination of consistency required by subsection (A) of this section.

C. All proposals within the ASD zone shall be subject to approval of the Federal Aviation Administration (FAA) if the FAA is an agency with jurisdiction on the proposal. [Ord. 720B § 1, 2002.]
