These documents contain communications from January 2017 regarding aircraft noise concerns over the Seahurst and White Center neighborhoods near Seattle-Tacoma International Airport. A noise consultant advises that Seahurst likely falls below the FAA's 65 dBA threshold that defines 'noise sensitive areas,' arguing this means an Environmental Assessment (EA) and historic property inventory are not required. Separately, a Burien resident emails city officials sharing research from Sea-Tac's Part 150 Study suggesting that flights over these neighborhoods were anticipated and approved, and that the absence of an EIS may not constitute valid grounds for litigation by the Quieter Skies coalition.Open full document
Notes
Two documents addressing legal and regulatory issues related to aircraft noise over Seahurst and White Center neighborhoods near Sea-Tac Airport. The first is an undated memo analyzing whether Seahurst qualifies as a ‘noise sensitive area’ under FAA Order 1050.1, arguing that since noise contours show levels below 65 dBA, an Environmental Assessment is unnecessary. The second is a January 11, 2017 email from Sharyn Parker to Burien city officials sharing research from Sea-Tac’s Part 150 Study that she believes may undermine the Quieter Skies Coalition’s litigation strategy regarding the absence of an EIS for new flight routes.
