The primary purpose of the SAMP is to identify facility improvements required to satisfy demand over the 20-year planning horizon and to balance capacity in all key functional areas to the fixed capacity of the airfield. To that end, the SAMP started with an unconstrained, 20-year forecast of cargo and passenger activity which was used to determine peak hour facility requirements based on demand derived from the movement of aircraft, passengers, bags, vehicles and freight. Alternatives for facilities development to satisfy demand were then developed and assessed, resulting in a phased capital program to deliver needed capacity through the 20-year planning horizon. For planning purposes, the SAMP assumes the airport’s current three-runway system and close- in airspace configuration will remain in place. With the airport’s small footprint and significant physical constraints, redevelopment at Sea-Tac requires expensive relocation of existing facilities and limited options for expansion. Work to evaluate alternatives for project phasing and to assess airside capacity has included extensive airside modeling…
