Three bar charts showing 7-day low flow occurrences modeled using 1994 HSPF (Hydrological Simulation Program Fortran) for the period 1949-1995. Charts cover Miller Creek, Des Moines Creek, and Walker Creek, displaying occurrence counts (0-4) by date ranging from summer through winter months (June through December). AR034949-AR034951. Related to stormwater hydrology and low flow analysis for

AR 018450 (DOE Misc 0033, Exhibit 191). Handwritten notes from a conference call between Seattle and City of Des Moines discussing what emergency action will override Section 401, Army Corps of Engineers regulation of indirect impacts, buffer activity language, and mitigation design. Dennis Ostencorp referenced as thinking about writing a letter on circular and mitigation

Handwritten meeting notes dated February 19, 2002, AR 026595–026597, attended by Pony Ellingson, Joe Brascher, Paul Fendt, Keith Smith, Felix Kristandovitch, Nick Stackellburg, Kelly Whiting, Ray Helwig, and Ed Abbasi. Topics include embankment model (Figure 5-4, Appendix B, Slice I model, MSE wall, infinite permeability assumption, coarse fill), fill modeling footprint area with surface groundwater

This document, labeled Exhibit E, contains photographs taken on January 31, 2002 of the Vacca Farm site, showing various land features including areas designated as Prior Converted Cropland, farmed wetlands, and Wetland A1. The photos document the site's vegetation and water features, including a close-up of wetland plants and a view of Miller Creek looking west across Wetland A1. The images appear to be part of an environmental or land-use assessment record related to the Vacca Farm property near Des Moines Way.

Declaration by Jeanne Moeller, Des Moines resident, filed January 10, 2002, in support of Airport Communities Coalition (ACC) Motion to Compel Inspection of Port Of Seattle property, PCHB Case No. 01-160.

Parametrix, Inc. prepared this Des Moines Way Nursery Mitigation Plan (AR 052455) for Port Of Seattle, Seattle-Tacoma International Airport, November 2001, project number 556-2912-001(03). The plan covers wetland restoration and enhancement at the Des Moines Way Nursery mitigation site, including grading design, expected hydrology, wildlife considerations, planting plan, vegetation monitoring, performance standards, maintenance and contingency

Handwritten meeting notes dated 7-11-01 (AR 018377, Exhibit 164) regarding Army Corps of Engineers issues with wetland functional assessment, hydrology (Lisa Scott, Corps hydrologist), adaptive management, sewer lines, upper water shed mitigation, and Des Moines Dr. wetland. Notes reference a loss of 1/10 CFS, temporary impacts from stockpile soils and microbes, revised performance standards, buffer

These draft meeting notes from July 9, 2001 document a technical working session between the Port of Seattle, Washington Department of Ecology, and King County regarding low stream flow analysis for the Sea-Tac International Airport Third Runway project. The group discussed methods for determining low flow impacts on fish habitat, reviewed a mitigation proposal for the Des Moines Watershed involving a 0.1 cfs compensatory flow release from July 24 through October 24, and received a status briefing on the Miller and Walker watershed analyses. Key topics included the use of 2-year 7-day low flow rates to calculate mitigation requirements, reserve vault sizing, and how to handle non-hydrologic effects such as water rights removal and septic system impacts in the property acquisition area.

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.

Final meeting notes prepared by Kate Snider of Floyd & Snider Inc. for the 401 Permit Decision-Making process for Seattle-Tacoma International Airport Third Runway, covering a Low Flow Analysis meeting held July 9, 2001. Attendees included representatives from Washington Department of Ecology (Ann Kenny, John Drabeck), King County (Kelly Whiting), Port Of Seattle (Keith Smith),
