Third Declaration of Paul S. Fendt (Parametrix, Inc.) filed in PCHB No. 01-160, Airport Communities Coalition v. Department of Ecology and Port Of Seattle. Fendt, licensed PE with 18+ years stormwater engineering experience, addresses calculation of summer low streamflow impacts on Miller Creek, Walker Creek, and Des Moines Creek for the Port Of Seattle Master

Second Pre-Hearing Order issued by the Pollution Control Hearings Board (PCHB) in case PCHB No. 01-160, Airport Communities Coalition (ACC) v. State of Washington Department of Ecology and Port Of Seattle.

This legal declaration by stormwater engineer Paul S. Fendt, filed before Washington's Pollution Control Hearings Board, addresses the Port of Seattle's Master Plan Update and its potential impacts on local stream flows in Miller, Walker, and Des Moines Creeks near Sea-Tac Airport. Fendt explains the use of the HSPF hydrologic model and a 2-year, 7-day low flow standard to assess and mitigate summer streamflow impacts resulting from planned airport expansion projects. He concludes that revised analysis shows no significant changes to previously calculated low flow impacts.

This 2001 legal declaration by civil engineer William Rozeboom, submitted to Washington's Pollution Control Hearings Board, challenges the Port of Seattle's stormwater and low-flow mitigation plans for the proposed third runway at Sea-Tac Airport. Rozeboom argues that the Port's analysis underestimates low-flow impacts on local streams and that the proposed underground storage vaults—equivalent in volume to more than seven Olympic-size swimming pools—are undersized. The declaration also disputes claims by Port engineer Paul Fendt that the water volumes involved are small and that mitigation can be easily adjusted.
