This 2017 technical memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines facility requirements for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. It covers planned needs across airfield operations, passenger terminals, ground access and parking, air cargo, and general aviation based on projected activity levels. The document provides detailed assessments of existing infrastructure and identifies future capacity and design requirements to accommodate long-term growth at Sea-Tac.

This document is a First Amendment to a Lease and Concession Agreement between the Port of Seattle and SP-LW, LLC, shifting the concessionaire's food and beverage operation from Unit CC-6 to Unit NS-23 in the North Satellite Terminal at Seattle-Tacoma International Airport. The amendment updates key lease terms, including an approximately 1,800-square-foot premises, a ten-year lease expiring December 31, 2031, and an initial minimum annual guarantee of $180,000. The Port also agreed to reimburse the concessionaire $360,095.72 for costs already incurred at the original unit.

This report from the Port of Seattle presents daily average noise levels recorded at Sea-Tac Airport monitoring stations (NMTs) throughout June 2017. It breaks down sound levels in decibels (dB LEQ) into three categories: community noise, aircraft noise, and a combined total, measured at more than 20 locations surrounding the airport. The data shows that aircraft noise levels frequently exceeded community noise levels at many monitoring sites, with some stations recording combined totals above 65 dB on multiple days.

Seattle-Tacoma International Airport's Environment and Sustainability Programs outline the airport's efforts to become the greenest, most energy-efficient airport in North America across four key areas: air quality and emissions reduction, green transportation, waste reduction and recycling, and water and wildlife management. Initiatives include providing pre-conditioned air and electricity at gates to cut aircraft engine greenhouse gas emissions by over 40,000 metric tons, transitioning vehicles to cleaner energy sources, and working toward recycling 60 percent of solid waste by 2020. The airport also actively manages 160 acres of wetland habitat, uses avian radar to protect wildlife, and has relocated more than 800 birds to reduce hazards to aircraft.

Seattle-Tacoma International Airport (Sea-Tac) has grown from a modest wartime airfield dedicated in 1944 on 906 acres of land near Bow Lake into one of the busiest airports in the United States, now serving nearly 47 million passengers annually. Over the decades, the airport underwent numerous expansions, security upgrades, and name controversies while navigating major events such as airline deregulation, the post-9/11 security overhaul, and a community-opposed third runway completed in 2008. Today, Sea-Tac supports more than 87,000 jobs and generates over $22 billion in economic activity for the region.
