TagSAMP Four City ILA(18)

The cities of Burien, Des Moines, Normandy Park, and SeaTac are renewing a cooperative agreement to jointly review and respond to the Port of Seattle's Sea-Tac Airport Sustainable Airport Master Plan (SAMP), which outlines future airport growth that could significantly impact neighboring communities. The new Interlocal Agreement (ILA), approved by Des Moines City Council in December 2024, extends collaboration through December 31, 2027, allowing the cities to share consultants and coordinate formal comments on the airport's environmental review process under NEPA and SEPA. Des Moines has committed up to $74,170 toward consultant services, with each city's share determined by relative population.

The Normandy Park City Council's December 10, 2024 agenda includes renewal of a lapsed Interlocal Agreement (ILA) among four cities — Normandy Park, Des Moines, Burien, and SeaTac — formed to coordinate review of the Port of Seattle's Sustainable Airport Master Plan (SAMP) and its environmental impacts. The renewed agreement removes a fixed expiration date, instead allowing the partnership to continue until the SAMP environmental review process is fully complete. Normandy Park contributes 5.6% of shared costs and has participated in the collaborative effort since the ILA's original adoption in March 2018.

A consulting team addresses two community concerns about Seattle-Tacoma International Airport: the lack of a direct NEPA environmental review covering noise impact growth between 2012 and 2018, and questions about how the airport's third runway is being used. The document explains that while current NEPA and Part 150 processes will capture existing noise conditions, they will not specifically compare 2012 versus 2018 impacts, and that federally funded runways like the third runway must be made available whenever air traffic control deems it necessary. The consultants propose reviewing historical Part 150 studies, past NEPA documents, and third-runway records to assess noise impacts on surrounding communities, while also supporting clients in engaging the Port, FAA, and airlines through the StART committee and other channels.

This March 2019 City Manager's Report from the City of Burien, Washington, covers a range of internal city updates including youth engagement programs, public safety initiatives, and community events. Topics include a Super Bowl youth event co-hosted with Burien Police and Highline School District, a safe firearm storage event, a Community Police Academy, and opioid treatment funding for the SCORE regional jail facility. The report does not contain information related to Sea-Tac Airport noise policy.

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.
