Resolution No. 3401 is a Port of Seattle Commission decision addressing aircraft noise reduction at Seattle-Tacoma International Airport (Sea-Tac). It requests that the FAA study the feasibility of routing more northbound departures through the Duwamish/Elliott Bay Corridor to reduce noise over residential neighborhoods, while also directing Port staff to explore increased nighttime use of the Commencement Bay flight track in coordination with Pierce County. The resolution follows a public review process involving Citizen and Technical Advisory Committees, which evaluated six alternative flight track options against a core criterion of improving overall noise conditions without simply shifting the burden from one community to another.Open full document
