1992-09-28Toledo-Winlock area visitation
A September 1992 internal memo from Doug Graves and Len Oebser to Rick Aramburu summarizes a site visit to the Toledo-Winlock area of Washington State as a potential location for a new replacement airport. The site was praised for its large size, proximity to the I-5 freeway midway between Seattle and Portland, access to Burlington Northern rail lines, and its sparsely populated surroundings, which would minimize noise and environmental impacts. However, drawbacks noted included its distance from major population centers such as Seattle, Tacoma, Everett, and Portland, which would require some form of mass rapid transit to serve the airport effectively. -

1984-01-16Jackson International Airport noise remedy update: Overall program boundaries
This 1984 draft document from the Port of Seattle outlines the Noise Remedy Update program for Seattle-Tacoma (Jackson) International Airport, defining geographic boundaries for three types of noise mitigation measures: property acquisition, purchase assurance, and sound insulation. The maps cover areas north through south of the airport, including neighborhoods such as Boulevard Park, Des Moines, Normandy Park, and Zenith, showing which zones qualify for each remedy based on aircraft noise exposure. Sound insulation coverage extends as far north as S. Kenyon Street, while acquisition zones are concentrated in the areas immediately surrounding the airport's runways. -
