Facsimile cover sheet dated 2-19-02 from Ray Hellwig, Washington State Department of Ecology Northwest Regional Office (Bellevue, WA), to Tom Young (AAG), transmitting 11 pages including a Port of Seattle memorandum dated February 7, 2002 and an Inter-local Agreement between State of Washington Department of Ecology and Port of Seattle for oversight of construction projects

These are handwritten field observation notes dated January 31, 2002, documenting wetland and upland buffer conditions near Miller Creek and Vacca Farm, including plant communities, wetland boundaries, and buffer zones. The notes reference site observations about existing wetland conditions, vegetation types (including cattails, alder, sedge, and Phalaris), and questions about the extent of wetland fill and excavation. The observations appear to relate to an environmental review of proposed land use changes adjacent to Miller Creek, with reference to an upland buffer plan (STA-7805).

This document is an agenda for a Low Streamflow Analysis Meeting held on February 19, 2002, at the Department of Ecology in Bellevue, Washington. The meeting covered technical modeling and water flow topics for three local waterways — Walker Creek, Miller Creek, and Des Moines Creek — including reviews of land cover tables, groundwater routing, and calibration. General topics such as water quality monitoring, channel hydraulics, and embankment modeling were also on the agenda.

These two aerial photographs, dated 1997 and 2001, show overhead views of Seattle-Tacoma International Airport (Sea-Tac) and its surrounding neighborhoods. The images, produced by Walker & Associates and entered as Exhibit 390 in a February 2002 proceeding, document the airport's runway layout and adjacent residential and commercial areas over time. They appear to be part of an administrative record (AR 021768–021769) related to airport noise policy or land-use impact analysis.

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 legal document is a supplemental response filed by the Airport Communities Coalition (ACC) in a Washington State Pollution Control Hearings Board case (No. 01-160) against the State Department of Ecology and the Port of Seattle. It lists scientific references and studies relied upon by ACC's expert witnesses, covering topics such as the effects of airport deicing chemicals on water quality, dissolved oxygen levels in receiving streams, fluoride impacts on salmon, and toxicity of stormwater runoff to aquatic life near Seattle-Tacoma International Airport.

This document is a map from the Port of Seattle showing the comprehensive storm drainage system plan and drainage basins for the Seattle port facility. It identifies stormwater drainage basin color codes, outfall locations, and pump station locations across the property. The figure was entered as Exhibit 379A on February 18, 2002, in proceedings recorded by C. Mangio, RMR, CRR.

This document, marked as Exhibit No. 382 from the Bailey proceeding dated 2-18-02, contains a photographic image that appears to show an aerial or ground-level view of a landscape, likely related to environmental or noise impact evidence near Sea-Tac Airport. The photograph, originally a high-resolution JPEG (1360x1020x24b), depicts what appears to be a roadway or runway corridor surrounded by terrain. It is part of the administrative record (AR 021693) compiled in connection with Sea-Tac Airport noise policy litigation or regulatory proceedings.
