Review and Evaluation of Sea-Tac Runway Fill Hydrologic Studies Report

Notes

A letter from Columbia Biological Assessments to attorneys for the Airport Communities Coalition (ACC) reviewing WDOE’s hydrologic studies report on the Sea-Tac runway fill project. The review evaluates impacts on aquifers, wetlands, and Miller, Walker, and Des Moines Creeks, focusing on fishery resources and aquatic life. The author critiques the report for understating wetland importance, inaccurately describing fishery resources, and inadequately assessing construction impacts on fish habitat in Miller Creek.
