2025-06-16Arborist Report: Port Of Seattle Industrial Wastewater Treatment Plan – AGB Site, Sea-Tac, WA
A June 2025 arborist report by Tree Solutions Inc. inventoried and assessed 181 trees across ten Port of Seattle parcels at the AGB Site near SeaTac Airport, finding the site largely dominated by red alders, black cottonwoods, and invasive plant species following demolition of previous buildings. The report identifies one notable high-value western redcedar (Tree 470, 31.8 inches in diameter) and outlines tree replacement requirements under Port of Seattle Resolution 3821, which mandates a 4-to-1 replacement ratio for any regulated trees removed during future construction. The report is preliminary, as no design or construction plans had been reviewed at the time of writing. -
