The cities of Burien, Des Moines, Normandy Park, and SeaTac entered into an interlocal agreement to coordinate their review of the Port of Seattle's Sustainable Airport Master Plan (SAMP), which proposes airport growth over the next 20 years that could significantly impact surrounding communities. The agreement establishes a shared process for analyzing environmental documents, issuing joint comment letters, and potentially hiring consultants to assist with the review under both federal (NEPA) and state (SEPA) environmental laws. Approved by the Burien City Council on February 5, 2018, the agreement outlines how the cities will fund, select, and manage any consultants retained to support this collaborative environmental oversight effort.

The cities of Burien, Des Moines, Normandy Park, and SeaTac entered into an interlocal agreement to coordinate their review of the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines airport growth over the next 20 years. The agreement establishes a process for the four cities to jointly analyze environmental impacts, submit coordinated comments under NEPA and SEPA, and potentially hire shared consultants to assist with their response. Approved by the Burien City Council on February 5, 2018, the agreement aims to give the neighboring cities a stronger, unified voice in evaluating potential negative impacts from Sea-Tac Airport expansion.

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.

In a July 2017 letter, Seattle-Tacoma International Airport's Managing Director Lance Lyttle acknowledged concerns from the City of Des Moines regarding the airport's Concourse D Hardstand Holdroom project, confirming that no additional gates would be added until the Sustainable Airport Master Plan (SAMP) environmental review was completed. Following this, the cities of Burien, Des Moines, Normandy Park, and SeaTac entered into an Interlocal Agreement in March 2018 to jointly hire the consulting firm Lockridge Grindal Nauen PLLP for $175,000 to conduct an environmental review of the SAMP. Costs were shared among the four cities based on a per-capita funding rate of approximately $1.50, with Burien covering the largest share at roughly 43%.
