    Airport Committee meeting – update on SAMP EIS – May 21, 2019

    In May 2019, Burien City Manager Brian Wilson updated the Burien Airport Committee on the cities' joint effort to respond to the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines airport expansion through 2027. The cities of Burien, Des Moines, Normandy Park, and SeaTac formed an Interlocal Agreement (ILA) and hired the Washington DC firm Lockridge Grindal Nauen to help review and comment on the SAMP's environmental impact process. Key community concerns raised in the accompanying September 2018 scoping letter include aircraft noise, air quality, traffic congestion, and the disproportionate burden placed on neighborhoods closest to Seattle-Tacoma International Airport.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects.

The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
