Stephen Felser digs into the details of the Port of Seattle's Sustainable Airport Master Plan (SAMP), a plan to account for growth in passenger and cargo service at Seattle-Tacoma International Airport over the next 20 years. The airport is already facing rapid growth, increasing passenger traffic by 8 percent between 2015 and 2016 and jumping from the 13th busiest airport in the United States to the ninth.

At the point, SAMP includes several alternatives for terminal expansion, as detailed in an April 2016 article also by Fesler. The terminal expansion portion of the plan is expected to wrap up the environmental review process later this year. Among the other capital investments under consideration are a new South Aviation Support Area, a new people mover, and a reconfigured roadway network.
