    Conservation Futures Tax Levy (CFT) application for 2022 funds: Des Moines Creek Expansion III

    The City of SeaTac applied for $1,105,000 in King County Conservation Futures Tax Levy funds in 2022 to purchase the final three acres of surplus Washington State Department of Transportation land adjacent to Des Moines Creek Park, bringing the total acquired acreage to eight acres. The project aims to preserve forested upland habitat along a salmon-bearing stream, improve public park access from the west side via 18th Avenue South, and support trail connectivity including the Lake to Sound Trail. This was the third phase of a multi-year acquisition effort, following prior CFT awards of $1.1 million in 2019 and $500,000 in 2020.

SeaTac's priorities notably include advocating for full funding of SR 509 and SR 518 transportation improvements through the Puget Sound Gateway project, which is directly tied to airport-related regional traffic, as well as supporting a University of Washington indoor air quality study near the airport to recommend health protections for local residents. Tukwila's agenda focuses more broadly on housing, racial equity, broadband access, law enforcement reform, and stable infrastructure funding from the state.

    Letter from City of Sea-Tac Mayor Erin Sitterley to Mark Barkley Regarding Seattle-Tacoma International Airport Study

    In a November 2019 letter to the Washington State Department of Commerce, SeaTac Mayor Erin Sitterley raised concerns about the management of the state-mandated Seattle-Tacoma International Airport Study, which SeaTac was funding to the tune of $150,000. The city questioned whether the study's consultant, Stantec, had strayed from the original technical scope of work, cited worries about monitoring stations placed outside the defined study area, and expressed doubt that the study could be completed on time and within budget. The letter demanded a full accounting of project expenditures—including consultant travel costs from Dallas—and requested that public input be limited until after a draft report was reviewed by the Technical Advisory Committee.

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.
