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 January 2018 letter to the Puget Sound Regional Council, Des Moines Mayor Matt Pina raised concerns about the disproportionate noise, air quality, and environmental burdens placed on Des Moines residents by Seattle-Tacoma International Airport's rapid growth, arguing these impacts are inadequately addressed in the Draft Regional Transportation Plan. The city called for sustainability, human health, and community impacts to be central factors in any decision to expand SeaTac's capacity or site a new regional airport. The letter also requested that the plan include discussion of a potential passenger ferry terminal in Des Moines as a multi-modal transportation alternative.

In an October 2017 email to Burien City Council members, resident Sharyn Parker critiques a letter from Port of Seattle Chairman Tom Albro defending Sea-Tac Airport's expansion and noise mitigation efforts. She argues that Albro's response fails to address the real-world impacts of rapidly increasing flight operations—including a 9% annual average flight increase—on surrounding communities, and that the Port's noise modeling data is outdated and understates actual activity by 51%. Parker calls on the Council to challenge what she characterizes as the Port's lack of candor and possible intentional underestimation of flight projections to avoid costly noise and air quality mitigation requirements.

In September 2017, Des Moines, WA resident Steve Edmiston sent a certified letter demanding that the Port of Seattle and the FAA stop increased flight operations over his historic Woodmont neighborhood, arguing that no avigation easement had ever been granted over his property. He cited a dramatic rise in aircraft noise, vibrations, fumes, and nighttime flights linked to expanded use of Sea-Tac's third runway and new navigation procedures, noting that commercial operations at the airport had nearly doubled since 2003. The letter also included a formal public records request for documents related to flight procedure changes made after February 14, 2012, and outlined legal grounds under which affected homeowners may still seek damages despite general noise liability limitations.

In this September 2015 letter, the Port of Seattle and the City of SeaTac reached a mutual agreement regarding the environmental review of Sea-Tac Airport's Sustainable Airport Master Plan (SAMP). The Port committed to conducting a full environmental analysis of all anticipated airport growth — including international passenger traffic — as part of the SAMP review process, addressing the City's concerns about transportation and other impacts. In exchange, the City agreed not to file an appeal on the Final Declaration of Non-Significance issued for the International Arrivals Facility project.

A May 2004 legal letter from Helsell Fetterman attorneys demands that the Port of Seattle and Washington State Ecology Department comply with a Washington Supreme Court ruling before proceeding with third runway construction at Sea-Tac Airport. The court imposed environmental conditions requiring that fill materials used in construction come only from uncontaminated sites, meet strict groundwater quality standards, and pass SPLP leachate testing against both surface and groundwater criteria. The letter argues that the Port's existing work plans and bid documents violate these court-mandated conditions, citing discrepancies such as the Port's allowable arsenic limit of 14.75 ug/L being several hundred times higher than the court-required 0.05 ug/L standard.

A 2001 community newsletter documenting widespread opposition to Sea-Tac Airport's proposed third runway construction, which required destroying 18 acres of wetlands. Residents, local elected officials, and independent experts raised serious concerns about earthquake safety, environmental damage to local streams and salmon habitat, and the structural integrity of four unprecedented earthen retaining walls planned for the project. The Port of Seattle's applications were repeatedly challenged and withdrawn due to fatal flaws in environmental planning and seismic risk analysis.
