Sustainable Airport Master Plan (SAMP) 

The Central Puget Sound region is expected to grow by another one million people by 2035. The Sustainable Airport Master Plan is the blueprint for changes at Sea-Tac Airport to meet future regional demand. In addition to considering forecasted passenger and cargo demand, the master plan takes stock of current facilities, infrastructure and operations — looking at scenarios five, 10, and 20 years in the future. It includes air quality, energy and water conservation, recycling and other strategic environmental goals, and will align with the Port’s sustainability and energy efficiency goals. Learn more.
