Resolution No. 3125, adopted by the Port of Seattle Commission in 1992, authorizes planning and environmental studies for the construction of a third runway at Seattle-Tacoma International Airport (Sea-Tac) to address growing air traffic demand and capacity limitations, particularly during poor weather conditions. The resolution follows a two-year study by the Puget Sound Air Transportation Committee (PSATC), which recommended a phased multiple-airport system, including a new dependent runway at Sea-Tac by 2000. The Port also called for broader regional solutions, including a fast rail link between Portland and Vancouver airports and diversion of cargo-only carriers to alternative airport sites.Open full document
