This document is an email chain from September 2001 in which King County's David Masters notifies Ann Kenny that spending on a contract for technical review services provided to the Washington State Department of Ecology has exceeded its $95,000 limit by $23,695. Masters proposes amending the contract to increase the budget by $170,000 to a new total of $265,000, covering anticipated work such as low-flow analysis, preparation of appeal materials, and potential expert witness testimony. Ann Kenny forwarded the information to Michael Cheyne to facilitate the contract amendment process.

In August 2001, King County's Department of Natural Resources wrote to the Washington Department of Ecology confirming that the Port of Seattle's Comprehensive Stormwater Management Plan for Sea-Tac International Airport Master Plan improvements met the technical requirements of the 1998 King County Surface Water Design Manual. The review found that the plan demonstrated a feasible conceptual strategy for managing stormwater from proposed airport construction projects. Reviewers noted that while the plan showed compliance with design standards, additional oversight and monitoring would be needed as individual projects moved from planning into construction.

In August 2001, King County's Department of Natural Resources submitted a technical review letter to the Washington Department of Ecology evaluating the Port of Seattle's Low Flow Impact Analysis and proposed offset facilities for stormwater management near Sea-Tac Airport. The review found the proposal goes well beyond the basic requirements of the King County Surface Water Design Manual and represents substantial mitigation for low flow impacts in affected drainage basins, including Miller and Walker Creeks. Reviewers noted several inconsistencies and data gaps in the documentation and recommended that a final consolidated document be prepared incorporating all corrections and technical memoranda.

Letter dated August 3, 2001 from Pam Bissonnette, Director of King County Department of Natural Resources, to Ann Kenny, Senior Permit Specialist at Washington Department of Ecology Northwest Regional Office, conveying King County’s technical review findings on the Port Of Seattle’s Comprehensive Stormwater Management Plan (SMP) for Master Plan Update (MPU) Improvements at Seattle-Tacoma International

These draft meeting notes from a July 9, 2001 technical meeting cover low flow analysis related to the 401 Permit decision-making process for Sea-Tac International Airport's Third Runway project. Attendees from the Department of Ecology, King County, Port of Seattle, and several consulting firms discussed methods for determining low stream flow impacts and mitigation requirements across affected watersheds. Key topics included biological effects on fish habitat, a proposed 0.1 cfs mitigation flow for the Des Moines Watershed, and the use of 2-year 7-day low flow rates to guide mitigation planning.
