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.

The City of SeaTac hosted a Highline Forum meeting on September 23, 2015, focused on legislative priorities for the 2016 session, including reviews of individual member legislative agendas and opportunities for regional collaboration. The agenda also references a Transit-Oriented Development Workshop held on October 6, 2015, co-hosted with Smart Growth America, which explored how investment in transit stations shapes community growth near the SeaTac area.

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.

This map from the City of SeaTac shows projected 2018 average day/night noise levels (DNL) radiating from Seattle-Tacoma International Airport, with contour zones indicating areas expected to experience noise levels of 65, 70, and 75 decibels. The noise contours extend north into Burien, south into Des Moines, and affect portions of Tukwila and Normandy Park, with the most intense noise zone (DNL 75) centered directly over the airport. Prepared in March 2015 using Port of Seattle Airport Noise Programs data from July 2014, the map serves as a planning reference for land use and noise mitigation policy in surrounding communities.
