Slide 44 from a Sea-Tac Airport (SEA) Environmental Impact Statement presentation comparing noise and visual effects impacts across three alternatives: No Action, Proposed Action, and Hybrid Terminal Option. Key findings indicate that while the 65 DNL noise contour would be larger under the Proposed Action in 2032 and 2037, no significant noise impacts would occur, and noise contours shrink by 2037 due to quieter Boeing 737 MAX aircraft.Open full document
