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.Open full document
