This technical report, prepared by Parametrix for the Port of Seattle in February 2024, documents the wetlands and streams found at Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan (SAMP) Near Term Projects. It covers the delineation of wetland and stream boundaries, assesses potential impacts to these aquatic areas from planned airport improvements, and outlines mitigation measures and permitting approaches to address those impacts.

This February 2024 technical report from the Port of Seattle documents the wetlands and streams located at and around Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan (SAMP). It includes mapped locations of wetlands surveyed across multiple years (2006, 2014, and 2017) along with stream corridors such as Miller Creek, Des Moines Creek, and Walker Creek. Field hydrology monitoring data from 2020 is also provided, recording groundwater depth and soil saturation measurements to assess wetland conditions across the airport property.

It covers the delineation of aquatic critical areas, assessments of potential project impacts on wetlands and waterways, proposed mitigation measures, and the permitting approach needed to address those impacts. The report also includes analysis of impervious surface changes and Federal Flood Risk Management Standard (FFRMS) compliance worksheets.

The Highline Forum held its January 24, 2024 meeting at Seattle-Tacoma International Airport, hosted by the Port of Seattle, focusing on 2024 state and federal legislative issues affecting communities near the airport. The hybrid meeting covered administrative matters, a StART (Sea-Tac Airport Roundtable) update from Aviation Managing Director Lance Lyttle, and allowed public comment in person, via email, or through Microsoft Teams. The Forum's 2024 schedule includes six bimonthly meetings hosted by rotating local jurisdictions, including Federal Way, Tukwila, Highline College, Des Moines, and SeaTac.

This is a fiscal note summary for Washington State Senate Bill 5955, which concerns large port districts. The document estimates that local governments could face operating expenditures of $100 million per biennium across multiple budget periods, while also projecting declining cash receipt losses to local governments ranging from approximately $867,000 in 2023-25 to over $8.5 million by 2027-29. The Office of State Treasurer notes non-zero but indeterminate cost impacts, and the Department of Commerce's fiscal note was not available at the time of publication in January 2024.

Washington Senate Bill 5955 would require large port districts operating airports with more than 900 daily flights — such as Sea-Tac — to launch a remedial mitigation program addressing failed soundproofing, air quality, green space, and community facilities in noise-impacted neighborhoods. The bill would fund these programs through a portion of the port's annual property tax levy revenue and establish a state environmental equity fund, managed by the Department of Commerce, to provide grants and loans to qualifying ports. Property owners within ten miles of the airport experiencing 55 decibels or more of aircraft noise would be eligible for free inspections and mitigation equipment, with priority given to homes where previously installed soundproofing has failed.
