Notes
A letter from Columbia Biological Assessments to the Washington Department of Fish and Wildlife evaluating the potential fishery impacts of the SR-509 temporary interchange construction project near Burien. The author concludes that the proposed construction will result in periodic stormwater discharges of sediment-laden waters to adjacent wetlands, adversely affecting water quality and harming fish species in Walker Creek. The letter also critiques Parametrix Inc.’s assessment as inadequate, noting insufficient documentation and failure to inventory fish species at risk.
