In September 2018, the cities of SeaTac, Burien, Normandy Park, and Des Moines submitted joint scoping comments urging the Port of Seattle to broaden its environmental review of the Sustainable Airport Master Plan (SAMP) beyond just near-term construction projects. The cities argued that cumulative impacts — including a projected 60% increase in aircraft operations and 75% rise in passengers by 2034 — require a full analysis of noise, air quality, and traffic effects on nearby communities. They also called for a baseline period starting in 2012, rather than 2018, to capture the significant growth and airspace changes that have already occurred without adequate environmental review.

The City of SeaTac submitted formal scoping comments to the Port of Seattle in September 2018, raising concerns that the environmental review for the Sustainable Airport Master Plan (SAMP) was too narrowly focused on 'near term projects' and should be expanded to cover the airport's full long-term growth vision. The city also reminded the Port of binding commitments made in a 2018 Interlocal Agreement and a 2015 Letter of Understanding, including promises to assess transportation impacts, protect nearby wetlands, and mitigate effects on city streets from increased cargo truck and passenger traffic. Key issues flagged include the impact of new cargo facilities, a proposed employee parking lot near wetlands, and the need to account for public transit use by airport workers and travelers.

In a March 2018 letter to the Puget Sound Regional Council, the City of Des Moines, Washington, expressed concerns about the disproportionate noise, air quality, and health impacts that SeaTac Airport's rapid growth places on nearby residents. The city urged that Vision 2050's environmental review include a serious evaluation of siting a second major commercial airport in western Washington to relieve capacity pressure on SeaTac. It also called for multi-modal transportation solutions and thorough analysis of jet fuel emissions and other environmental impacts as part of regional aviation planning.

In a June 21, 2017 letter to the Port of Seattle, the City of Des Moines raised concerns about the SEPA Determination of Nonsignificance for the Concourse D Hardstand Holdroom project at Sea-Tac Airport, questioning whether the facility was truly limited to serving existing passenger levels or was also intended to support future growth. The city argued that the DNS should clarify how the project relates to the Sustainable Airport Master Plan and future expansion. Des Moines emphasized that its residents already bear disproportionate noise and health impacts from airport operations and requested thorough environmental analysis and appropriate mitigation for any airport facility enhancements.

This SEPA environmental checklist prepared by the Port of Seattle covers the proposed renovation and expansion of the North Satellite Terminal at Seattle-Tacoma International Airport. The project would expand the terminal footprint from 91,500 to 154,500 square feet, adding eight new airplane gates for a total of twenty contact gates. Construction was planned in two

Ordinance No. 1583 is an environmental regulations ordinance from the City of Des Moines, Washington, that replaces and reorganizes the city's Title 16 Environmental Code. It implements state laws covering environmental policy, critical areas, floodplain management, and shoreline protection, while providing definitions and general provisions applicable across all related chapters.

Resolution No. 3650 was adopted by the Port of Seattle Commission on May 3, 2011, updating the Port's policies and procedures under the State Environmental Policy Act (SEPA) to reflect changes in law and improve effectiveness. The resolution requires the Port to analyze and, where appropriate, mitigate the environmental impacts of its proposals, including consideration of greenhouse gas emissions and climate change. It supersedes all prior related resolutions and formally designates policies that may be used to condition or deny actions under SEPA's substantive authority.

The VISION 2040 Supplemental Draft Environmental Impact Statement, published by the Puget Sound Regional Council in July 2007, identifies a Preferred Growth Alternative for managing forecasted population and development growth in the Puget Sound region through the year 2040. It supplements a May 2006 Draft EIS that examined four conceptual growth alternatives, adding analysis of environmental impacts associated with the preferred option. The document was prepared in accordance with Washington State's Environmental Policy Act and invites public comment on regional growth planning policies.

This 2002 executive briefing presents the draft Master Plan and environmental review documents (SEPA/EIS and NEPA/EA) for King County International Airport (Boeing Field), located five miles south of downtown Seattle. The airport, which covers 594 acres and hosts 150 tenant businesses and 479 based aircraft, recorded approximately 290,000 flight operations in 2001. The FAA accepted the Master Plan in Fall 2001 and approved the Airport Layout Plan in March 2002, setting the stage for future development and noise impact assessments.
