The cities of Burien, Des Moines, and SeaTac held a Community Open House to demand equity for communities impacted by Sea-Tac Airport, presenting concerns about a Draft Environmental Impact Statement (DEIS). The cities argue the DEIS fails to adequately address hazardous materials risks—including incomplete PFAS contamination mapping and insufficient evaluation of off-site pollution migration—and does not properly demonstrate how airport expansion affects nearby neighborhoods, parks, and land use. Key deficiencies identified include reliance on future regulatory compliance rather than current evidence, and a lack of clear analysis linking land use conclusions to technical findings.Open full document
Notes
Presentation boards from a community open house hosted by Burien, Des Moines, and SeaTac focused on equity concerns related to the Sustainable Airport Master Plan (SAMP). The materials highlight deficiencies in the Draft Environmental Impact Statement (DEIS), including inadequate analysis of hazardous materials impacts and land use compatibility. The boards identify specific technical deficiencies such as incomplete PFAS contamination delineation and insufficient evaluation of cargo-related land use intensity shifts.
