At a March 12, 2018 Aviation Advisory Committee meeting, the City of Des Moines raised concerns that Sea-Tac Airport was approving capacity-expanding projects — including the North Satellite, International Arrivals Facility, and Concourse D Hardstand Holdroom — on a piecemeal basis rather than evaluating their combined environmental impacts together. The City sent a letter to the Airport's Managing Director arguing that treating these projects as part of the baseline 'future condition' in the Sustainable Airport Master Plan (SAMP) environmental review, rather than as growth-related additions, was unacceptable and contradicted prior commitments. Des Moines requested clarification and a reaffirmation that the cumulative capacity and noise impacts of these projects would be fully analyzed in the SAMP review, citing disproportionate noise and health burdens on residents living near the airport.Open full document

Also includes a draft letter from Des Moines City Manager Michael Matthias to Lance Lyttle, Managing Director of Seattle-Tacoma International Airport, expressing concern that capacity-adding projects (North Satellite, International Arrivals Facility, Concourse D Hardstand Holdroom) were being characterized as ‘future baseline’ in SAMP environmental review rather than as growth-related projects. The City requests clarification and reaffirmation that these projects will be fully evaluated for cumulative environmental impacts in the SAMP review.
