18.48.270 Airport height map.
A. The owner or manager of a public airport may prepare for filing with the planning department and approval of the land use administrator a proposed airport height map. A proposed airport height map becomes an approved airport height map upon the written approval of the map as meeting the requirements of this section by the land use administrator set out upon or appended to the map.
B. The map shall be prepared in a manner that shows the airspace zones as defined and set forth in Federal Aviation Regulations, Part 77, subpart C, that are applicable to the airport. The map may consist of more than one (1) sheet, shall be to scale and shall accurately show the following:
1. The exterior boundaries of the applicable air space zones;
2. The name or other identification of each of the airspace zones;
3. A legend that provides a description of the location of each zone or surface, including a reference to the paragraph in the Federal Aviation Regulations that describes the zone or surface;
4. The reference points within or outside the airport from which distance, elevation, height, bearing, vertical angle or other measurements are made in describing the airspace zones or surfaces;
5. Existing topography, if available;
6. Existing subdivisions, streets, roads and other rights of way, U.S. Surveys, section lines and similar features of land that will be useful in determining the location of a proposed development with respect to the boundaries of any airspace zone.
C. The map required by subsection A of this section shall accurately show the airspace zones. Airspace zones that have a sloping surface shall be shown in ten- (10-) foot increments unless the land use administrator requires more frequent contour lines close to the airport or permits larger increments in areas farther from the airport. Separate maps may be submitted for the different airspace zones. Before submission to the land use administrator for final approval, the map must have been certified by the Federal Aviation Administration as accurately depicting the requirements of the relevant Federal Aviation Regulations, Part 77, subpart C. Upon reasonable intervals, and upon learning of a change in the airport or applicable regulations, the land use administrator may request Federal Aviation Administration review and recertification of the airport height map.
