Notes
Joint comment letter dated December 12, 2024, submitted by the Cities of Burien, Normandy Park, SeaTac, and Des Moines to Port Of Seattle Aviation Environment and Sustainability (Steve Rybolt) regarding the Seattle-Tacoma International Airport (SEA) Sustainable Airport Master Plan (SAMP) Draft Environmental Assessment (EA). Letter raises concerns about: insufficient public comment period timeframe; aircraft noise impacts including DNL 65 dBA contour expansion affecting 22,000 residents by 2032 (up 37% from 14,061 in 2022); 20% increase in annual operations to 511,800 by 2032; 25% increase in nighttime arrivals; disproportionate environmental justice impacts on minority and low-income communities in south King County; absence of noise mitigation measures in EA; deficiencies in Part 150 sound insulation program contractor quality; and requests for proactive Port Of Seattle collaboration with impacted cities under NEPA.
