In September 2013, the FAA's Seattle Airports District Office issued a $3,900,000 grant offer to the Port of Seattle for Seattle-Tacoma International Airport under AIP Project Number 3-53-0062-131-2013. The grant agreement was fully executed by September 12, 2013, meeting the required acceptance deadline of September 13, 2013. All environmental analysis and approval requirements were fulfilled in accordance with FAA Order 5050.4B, the Airport Environmental Handbook.

This July 2013 Port of Seattle Commission briefing outlines plans for expanding the International Arrivals Facility (IAF) at Seattle-Tacoma International Airport. It reviews existing conditions for arriving international passengers, evaluates two facility expansion alternatives, and discusses modest near-term improvements to the current facility. The briefing is framed within the Commission's Century Agenda, a 25-year vision to make Sea-Tac the West Coast's premier international travel gateway by doubling international flights and destinations.

A 2013 Port of Seattle staff briefing outlines the growing strain on Seattle-Tacoma International Airport's international arrivals facilities, noting a 59% increase in passengers requiring federal inspection since 2004 and severe mid-day congestion. To support the Port's goal of doubling international flights over 25 years, staff proposed building a new International Arrivals Facility estimated to cost between $250 million and $400 million. The document details capacity problems, economic benefits of international flights, and requests Commission authorization to begin project planning and funding.

The Northwest Ports Clean Air Strategy 2013 Update is a collaborative environmental initiative developed by the Port of Seattle, Port of Tacoma, and Port Metro Vancouver to reduce air pollution from port-related activities such as ocean-going vessels, cargo-handling equipment, trucks, and locomotives. The strategy sets emission-reduction goals for diesel particulate matter and greenhouse gases by 2015 and 2020, with performance targets across six sectors. Partner agencies including the EPA, Environment Canada, and the Washington State Department of Ecology contributed to the plan.

This exhibit from the Seattle-Tacoma International Airport 14 CFR Part 150 Study maps the existing 2013 baseline noise exposure contours around Sea-Tac Airport, showing DNL 65, 70, and 75 dBA noise zones across surrounding communities including SeaTac, Burien, Des Moines, and Tukwila. The DNL 65 dBA or greater contour covers approximately 5.9 square miles, encompassing an estimated 1,887 housing units and roughly 4,879 residents, along with 9 noise-sensitive facilities such as schools, churches, and hospitals. Notably, no housing units fall within the higher-impact DNL 70 dBA or above zones, though significant residential and commercial land uses exist within the broader 65 dBA contour area.

A May 2013 presentation by City of Burien staff to the Highline Forum explores potential partnerships between local cities, the Highline School District, and the Port of Seattle, focusing on shared community interests and collaboration opportunities. The presentation covers Burien's community vision, historical context, current conditions, school performance data, and specific areas where the city has a stake in local schools. It lays out a case for deeper, more structured cooperation among these regional institutions to strengthen the broader South King County community.

The Port of Seattle issued a State Environmental Policy Act (SEPA) Determination of Non-Significance for the Sea-Tac Airport Part 150 Noise Compatibility Planning Study, concluding the plan would not have a significant adverse impact on the environment. The study outlines 23 noise mitigation measures—including limiting nighttime flights, sound-insulating homes and schools, and constructing a Ground Run-Up Enclosure—aimed at reducing aircraft noise for communities surrounding Seattle-Tacoma International Airport. A 45-day public comment period was open through May 30, 2013, with the determination signed by Elizabeth Leavitt, Director of Aviation Planning and Environmental Programs.
