Notes

Declaration by Paul S. Fendt, a stormwater engineer with Parametrix Inc., submitted to the Pollution Control Hearings Board in Airport Communities Coalition v. Department of Ecology and Port of Seattle. The declaration addresses the calculation of summer low streamflow impacts on Miller, Walker, and Des Moines Creeks resulting from the Port of Seattle’s Master Plan Update projects. It describes the HSPF hydrologic modeling methodology used to evaluate existing and future conditions and determine the 2-year, 7-day low flow standard for impact and mitigation evaluation.
