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%.

This December 2016 advertising supplement from the Tomorrow@Sea-Tac Coalition outlines the Port of Seattle's plans to expand and modernize Seattle-Tacoma International Airport, which was the fastest-growing major hub in the country and expected to reach 66 million passengers by 2034. The document highlights billions of dollars in planned capital improvements under a Sustainable Airport Master Plan, covering aircraft operations, passenger facilities, and cargo services, while emphasizing commitments to environmental sustainability. It also spotlights workforce development efforts, noting that Sea-Tac directly and indirectly supports nearly 172,000 regional jobs and actively works to create opportunities for diverse and minority-owned businesses in surrounding South King County communities.

This June 2016 Port of Seattle staff memo updates the Commission on the Sustainable Airport Master Plan (SAMP) for Sea-Tac Airport, summarizing progress on airside capacity modeling, terminal expansion options, and a series of public roundtable forums on topics such as environmental sustainability, community impacts, and airline needs. Modeling indicates the airfield will reach critical delay levels between 2029 and 2034, making infrastructure improvements such as aircraft hold positions essential. The memo outlines next steps toward narrowing master plan alternatives to one or two options for formal environmental review later in 2016.
