This document is the professional curriculum vitae of Dyanne Sheldon, principal of Sheldon & Associates, Inc., a Seattle-based wetland ecology consulting firm. Among her relevant work, she co-authored both the Sea-Tac Airport Wetland Inventory and the Sea-Tac Airport Wetland Management Plan in 1991 for the Port of Seattle's Environmental Management Section. Her broader expertise spans wetland delineation, habitat restoration, environmental planning, and regulatory compliance across the Pacific Northwest.

This document provides a professional biography and project portfolio for Amanda Azous, an environmental scientist and sole proprietor of Azous Environmental Sciences based in Washington State. Her work focuses on wetland delineation, ecological restoration, watershed analysis, and land use planning, primarily in the San Juan County and Puget Sound regions. While her expertise informs broader environmental policy in Washington State, this document contains no information directly related to Sea-Tac Airport noise policy.

This 2002 staff report from the City of SeaTac and City of Des Moines addresses an appeal by King County Water District #54 challenging an environmental (SEPA) determination related to the Des Moines Creek Basin Restoration Projects, a multi-agency effort to reduce stormwater damage and protect water quality near the Tyee Golf Course. The water district argued that the environmental review failed to adequately address potential impacts to the Highline aquifer, which serves as its sole water supply source. The hearing was scheduled before a Hearing Examiner on October 10, 2002.

This is a King County Superior Court case schedule order for an administrative appeal, signed by Presiding Judge Richard D. Eadie on September 6, 2002. The order sets key deadlines for the case, including filing of briefs, administrative agency records, and a review hearing date of April 7, 2003. All parties are required to comply with the schedule, as failure to meet deadlines could result in dismissal of the appeal.

A soil contamination study by Washington State's Department of Ecology and Public Health – Seattle & King County found elevated levels of arsenic and lead in southern King County soils, linked primarily to the former Asarco smelter in Ruston. Contamination levels were highest near the smelter and on Vashon and Maury Islands, with concentrations decreasing further from the source and following prevailing wind patterns. While the findings are a concern rather than an emergency, officials stress that the study reflects regional trends only and cannot predict contamination levels at individual properties.

In May 2002, the Seattle Council on Airport Affairs (SCAA) urged King County Executive Ron Sims to advance the King County International Airport (Boeing Field) Part 150 Noise Study to the FAA for review, approval, and federal funding. The letter highlights years of unresolved noise complaints from nearby residents and outlines a draft review covering fiscal impacts, detailed comments, and prior noise reduction plans. The SCAA emphasized that implementing the study's recommendations would likely carry no negative fiscal implications for the county, but that progress depended on the county promptly forwarding its proposals to the FAA.

King County Department of Natural Resources draft review comments (AR034844-034846) on the Port Of Seattle / Parametrix Inc. December 2001 Low Streamflow Analysis – Summer Low Flow Impact Offset Facility Proposal. Review evaluates HSPF hydrologic modeling, impact assessment, and conceptual design of low-flow offset facilities for Miller Creek and Walker Creek against Washington State Department

In December 2001, Hart Crowser, Inc. submitted Washington State Department of Revenue forms to the Department of Ecology certifying an environmental remedial action at a property located at the corner of NE 4th Street and 108th Avenue in Bellevue, King County. The Professional Certification was signed by Matthew F. Schultz, P.E., confirming that the cleanup was conducted independently and in a manner consistent with Washington's Model Toxics Control Act (MTCA). The filing sought a Washington State sales tax exemption and business and occupation tax credit for the environmental remedial action project (J-7600000).

These draft meeting notes from October 30, 2001 document a technical review session in which Port of Seattle consultants disclosed and explained several errors found in the low streamflow modeling for the Sea-Tac Airport Third Runway project. The key errors included a 1/24th magnitude conversion factor mistake in embankment fill data input, incorrect input files used for embankment modeling, and an overlap in which approximately 8 acres of the Walker Creek embankment appeared to be counted in both the Hydrus embankment model and the HSPF stream model. The meeting outlined corrective steps to be taken by the Port's consulting team to fix these errors before finalizing the revised Low Streamflow Analysis required under 401 Permit conditions.
