Final meeting notes prepared by Kate Snider of Floyd & Snider Inc. for the 401 Permit Decision-Making process for the Sea-Tac International Airport Third Runway project, covering Low Flow Analysis discussions held June 25, 2001. Attendees included representatives from Washington State Department of Ecology (Ann Kenny, John Drabeck), King County (Kelly Whiting), Port of Seattle

Northwest Hydraulic Consultants submitted follow-up technical comments to the U.S. Army Corps of Engineers and Washington State Department of Ecology regarding stormwater, hydrology, and hydraulics concerns related to the proposed third runway at Seattle-Tacoma International Airport. The letter, written on behalf of the Airport Communities Coalition, challenges the Port of Seattle's responses to earlier criticisms, raising unresolved issues about stormwater management standards, independent design review, cost estimates for detention facilities, and the accuracy of hydrological modeling. Key concerns include ambiguity in which stormwater standards will apply, inadequate quality assurance processes, and inconsistencies in the project's Stormwater Management Plan.

These are meeting notes from a June 25, 2001 technical meeting regarding the 401 Permit Decision-Making process for the Sea-Tac International Airport Third Runway project, focused on analyzing low stream flow impacts. Participants from the Department of Ecology, King County, Port of Seattle, and various consulting firms discussed methodologies for evaluating water flow modeling results, vault filling estimates, and potential mitigation requirements for affected streams. Modeling results were not yet available at the time of the meeting, and a follow-up meeting was scheduled for July 9, 2001 to review completed modeling output and determine any required mitigation measures.
