    Future Sea-Tac Airport Expansion — Independent Runway Plans East (Runway B, 1 Mile) and West (Runway A, 4,300 ft) of 34R

    This document presents two conceptual expansion plans for Seattle-Tacoma (Sea-Tac) Airport, showing proposed future runway configurations including an independent runway located one mile east of runway 34R (Plan A shows an alternative 4,300 feet west of 34R). The drawings detail proposed taxiways, satellite terminals, a future commuter runway, an underground tram system, and associated ground infrastructure such as off-site parking and hotel/business core areas. These plans were likely developed as part of noise and capacity planning studies to evaluate how additional independent runways could affect surrounding communities, including areas near Angle Lake, Bow Lake, and along key corridors such as International Boulevard and Des Moines Way South.
