Final meeting notes from October 30, 2001 Low Flow Analysis meeting regarding Port Of Seattle’s revisions to the Low Streamflow Analysis and Summer Low Flow Impact Offset Facility Proposal per 401 Permit conditions for Sea-Tac Airport Third Runway. Attendees included Ann Kenny (Dept. of Ecology), Kelly Whiting and David Masters (King County), Lisa Scott (Corps

Memorandum dated October 30, 2001 from Michael Kenrick of Hart Crowser, Inc. to Jim Thomson of HNTB (project number 4978-06), CC Elizabeth Leavitt of Port Of Seattle, regarding wetland hydrology impacts of the Third Runway Embankment Fill at Sea-Tac Airport. Covers depression wetlands, slope wetlands, and riparian wetlands; references FEIS for the Master Plan Update

A October 26, 2001 transmittal from Parametrix, Inc. to the U.S. Army Corps of Engineers (ACOE) provides responses to the ACOE's request for additional information regarding the Seattle-Tacoma International Airport (STIA) Master Plan Update (MPU) Natural Resource Mitigation project. The package includes maps and aerial photographs identifying wetland areas and acreages within Borrow Area 1, submitted on behalf of the Port of Seattle.

In this October 24, 2001 letter, the Port of Seattle notified the Washington Department of Ecology of a mathematical error discovered in hydrological modeling software used to assess the Seattle-Tacoma International Airport Master Plan's impacts on Miller and Walker Creeks. The error caused stream flow impacts to be overestimated at 1/24th of their actual value, meaning required mitigation facilities could be smaller than originally planned. As a result, the Port requested an extension of the Low Streamflow Analysis submittal deadline from November 5 to November 21, 2001.

This document contains an email chain from October 2001 coordinating a technical meeting among Port of Seattle staff and consultants to discuss low flow modeling issues at Sea-Tac Airport. The meeting, held on October 30, 2001 at Floyd Snider McCarthy's Seattle office, was scheduled to cover a low flow modeling error, revised modeling results and their effects on low flow reserve vaults, and potential additional modeling changes suggested by a Norm Crawford review. Key participants included Port of Seattle Water Resources Manager Keith Smith, consultant Kate Snider, and several other technical staff and engineers.
