  • City of SeaTac primary Interlocal Agreements with Port of Seattle (ILA)

    The City of SeaTac has had a unique relationship with 1Sea-Tac Airport since its founding in 1990. (Fun fact: the originally proposed city boundaries did not include the property which now comprises 43% of its land area.) But as soon as the decision was made, how to benefit from the relationship with the Port of

    The City of SeaTac passed a resolution creating the Port of Seattle Negotiation Committee (PNC), an ad hoc council committee tasked with guiding negotiations between the city and the Port of Seattle, which owns and operates Seattle-Tacoma International Airport. The committee, composed of Deputy Mayor Senayet Negusse, Councilmember Peter Kwon, and Councilmember Joe Vinson, will work toward developing a new Interlocal Agreement to replace the current 2018 agreement set to expire in February 2028. The resolution also authorizes the City Manager to formally initiate those negotiations with the Port of Seattle.

    Legal Services Agreement Regarding Issues Regarding Port Of Seattle’s Sustainable Airport Master Plan (SAMP)

    The cities of Burien, Des Moines, and SeaTac have jointly hired the law firm Leech Tishman Fuscaldo & Lampl to challenge the Federal Aviation Administration's approval of the Port of Seattle's Sustainable Airport Master Plan (SAMP). The firm will file a Petition for Review in the U.S. Court of Appeals for the Ninth Circuit, naming the FAA as the respondent. Under the agreement, SeaTac will receive and pay all legal invoices on behalf of the three cities, with legal fees starting with a $10,000 retainer and billed at $540 per hour for the lead attorney.

    Sea-Tac City Council Request for Council Action: Agenda Bill 6794 — Authorization for Legal Services Letters of Engagement, Four-City Interlocal Agreement Amendment, and 2025-2026 Budget Amendment for SAMP NEPA/SEPA Review

    The SeaTac City Council is considering an ordinance to hire outside legal counsel and update a cost-sharing agreement with the cities of Burien, Normandy Park, and Des Moines to challenge or engage with the FAA's environmental review of Seattle-Tacoma International Airport expansion plans. The four cities would jointly retain two law firms—Leech Tishman for federal NEPA matters and Ogden Murphy Wallace for state SEPA matters—at an estimated cost of $350,000, with SeaTac covering roughly 26% and recovering the rest from its partner cities. The effort is driven by the FAA's September 2025 issuance of a Final Environmental Assessment and Finding of No Significant Impact, which must be challenged by November 25, 2025.

    Des Moines Creek Basin Committee: Options for Moving Forward

    This April 2023 presentation by Erin Nelson outlines options for the Des Moines Creek Basin Committee as it prepares to renew its Interlocal Agreement (ILA), a cooperative arrangement among local jurisdictions managing the creek basin near Des Moines, Washington. The meeting agenda covers a review of past studies and committee accomplishments, a discussion of what has worked and what needs improvement, and a decision on workable paths forward. While focused on stormwater and creek basin management rather than airport noise policy directly, the Des Moines Creek basin is located adjacent to Sea-Tac Airport and its management is relevant to the broader environmental context of the surrounding area.

    Airport Committee meeting – update on SAMP EIS – May 21, 2019

    In May 2019, Burien City Manager Brian Wilson updated the Burien Airport Committee on the cities' joint effort to respond to the Port of Seattle's Sustainable Airport Master Plan (SAMP), which outlines airport expansion through 2027. The cities of Burien, Des Moines, Normandy Park, and SeaTac formed an Interlocal Agreement (ILA) and hired the Washington DC firm Lockridge Grindal Nauen to help review and comment on the SAMP's environmental impact process. Key community concerns raised in the accompanying September 2018 scoping letter include aircraft noise, air quality, traffic congestion, and the disproportionate burden placed on neighborhoods closest to Seattle-Tacoma International Airport.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
