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.

The Highline Forum held on July 26, 2017, at SeaTac City Hall brought together community stakeholders, city officials, and representatives from WSDOT and the Port of Seattle to discuss key regional topics including the SR 509 Puget Sound Gateway Program, aircraft altitude concerns, and air quality initiatives near Sea-Tac Airport. Presentations were delivered by Port of Seattle staff covering noise programs and environmental initiatives, alongside updates on SeaTac's economic development. The meeting provided a public forum for emerging issues and planning for future discussions on airport-related impacts to surrounding communities.

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.

The 2005 Interlocal Agreement (ILA-2), signed February 16, 2006, is a formal cooperative agreement between the City of SeaTac and the Port of Seattle governing a range of shared responsibilities related to Seattle-Tacoma International Airport. It covers topics including land use and zoning, surface water management, transportation, public safety, and noise policy, while also establishing financial commitments and dispute resolution procedures. The agreement builds on prior 2001 and 2004 interlocal agreements and sets out a framework for ongoing interagency cooperation on airport development and its impacts on the surrounding community.

This is Amendment No. 3 to a 2005 Interlocal Agreement between the Port of Seattle and the City of SeaTac, entered into on February 16, 2006, governing transportation planning and funding around Seattle-Tacoma International Airport. The amendment updates project management responsibilities and budget allocations for capital improvement projects, including the South Access roadway, SR 518 improvements, and the South Link Project on 28th Ave. S., funded through a local parking tax. It establishes rules for how parking tax revenues are divided among projects and outlines corrective actions if actual revenues fall short of forecasts.
