    Grid 1: 2013 Baseline Map — Des Moines and Sea-Tac Area Schools

    This map covers the Des Moines and SeaTac area in Washington State, showing residential streets, major roads including SR 99, SR 509, SR 516, and Interstate 5, along with several schools such as Mt. Rainier High School, Pacific Middle School, Midway Elementary, Des Moines Elementary, and St. Philomena School. A purple diagonal corridor crosses the map, likely representing a flight path or noise contour zone associated with Seattle-Tacoma International Airport, while an orange boundary outlines a specific study or impact area in the southern portion of the map. The document appears to be part of an airport noise or land-use planning study examining how SeaTac flight operations affect surrounding communities.

    Sea-Tac Airport Flight Track Map: South Flow Jet Deviations Due to Weather, May 24, 2006

    This Port of Seattle document shows a flight-track map of Seattle-Tacoma (Sea-Tac) Airport activity on May 24, 2006, between 5:45 p.m. and 8:30 p.m. During this period, south-flow jet aircraft deviated from their standard routes due to weather conditions, as confirmed by the FAA. The map distinguishes arrivals, departures, fly-overs, training flights, and overshoots by color, illustrating how unusual flight paths spread noise impacts across a wider area of the surrounding region.
