This April 2023 presentation by Erin Nelson outlines options for the Des Moines Creek Basin Committee as it prepares to renew its Interlocal Agreement (ILA), a cooperative arrangement among local jurisdictions managing the creek basin near Des Moines, Washington. The meeting agenda covers a review of past studies and committee accomplishments, a discussion of what has worked and what needs improvement, and a decision on workable paths forward. While focused on stormwater and creek basin management rather than airport noise policy directly, the Des Moines Creek basin is located adjacent to Sea-Tac Airport and its management is relevant to the broader environmental context of the surrounding area.

In May 2019, Burien City Manager Brian Wilson updated the Burien Airport Committee on the cities' joint effort to respond to the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines airport expansion through 2027. The cities of Burien, Des Moines, Normandy Park, and SeaTac formed an Interlocal Agreement (ILA) and hired the Washington DC firm Lockridge Grindal Nauen to help review and comment on the SAMP's environmental impact process. Key community concerns raised in the accompanying September 2018 scoping letter include aircraft noise, air quality, traffic congestion, and the disproportionate burden placed on neighborhoods closest to Seattle-Tacoma International Airport.

Six cities near Seattle — Burien, Des Moines, Normandy Park, Federal Way, Tukwila, and SeaTac — entered into an interlocal agreement to jointly provide $300,000 in local matching funds required by the Washington State Legislature to commission a study of the current and ongoing impacts of Seattle-Tacoma International Airport. SeaTac serves as the lead fiscal agent, collecting each city's proportional share (Burien's portion is $37,238.24) and transferring the pooled funds to the Washington State Department of Commerce, which will hire a consultant to conduct the study. The agreement outlines each party's financial obligations, administrative responsibilities, and dispute resolution procedures to ensure the study moves forward in a timely manner.

The 2018 Interlocal Agreement is a formal cooperation agreement between the Port of Seattle and the City of SeaTac governing how the two entities work together on land use, transportation, permitting, and development standards around Seattle-Tacoma International Airport. It establishes rules for zoning, airport activity areas, building permits, traffic impacts, and financial contributions, while also setting up processes for resolving disputes and coordinating on shared legislative priorities. The agreement aims to balance the airport's operational needs with the interests of the surrounding SeaTac community.

The 2018 Interlocal Agreement between the City of SeaTac and the Port of Seattle establishes a cooperative framework governing how Seattle-Tacoma International Airport operates within city boundaries, covering land use, building permits, environmental regulations, transportation, and public safety. The agreement, negotiated throughout 2017, includes provisions for storm water management fees, traffic impact fees, and an annual $1.4 million Port contribution to the City for community relief and public safety services. It also defines roles for environmental review under SEPA, including responsibilities related to noise impacts and aviation hazards affecting neighboring residents and businesses.

In December 2017, the Port of Seattle and the City of SeaTac approved a new ten-year Interlocal Agreement (ILA) to formalize their working relationship and address the overlapping responsibilities that arise from Sea-Tac Airport occupying over 40 percent of the city's land area. The agreement covers key issues such as public safety, traffic enforcement, land use, stormwater fees, and development permits, while aiming to reduce the potential for legal disputes between the two agencies. It builds on a partnership dating back to the city's incorporation in 1990 and replaces a prior agreement that was set to expire in early 2018.

This November 2017 City Council study session presentation outlines a proposed 2018 Interlocal Agreement (ILA) between the City of SeaTac and the Port of Seattle, which operates Seattle-Tacoma International Airport. Because Port properties make up 42% of SeaTac's total land area and the airport creates unique demands on city services, the two governments have used ILAs since 1997 to manage operational and authority issues. The proposed agreement, intended to replace the expiring February 2018 ILA, aims to improve efficiency, reduce costs, and avoid litigation through a mutually beneficial, comprehensive package of terms.
