In 2001, the King County Superior Court issued findings of fact and conclusions of law in an eminent domain case where the Port of Seattle condemned a 2.44-acre parcel (Parcel 92) at 15416 Des Moines Memorial Drive in SeaTac to support its Third Runway project, using the land as a flood plain. The property, owned by RST Enterprises and zoned single-family residential (UL-7200), had been used for farming for at least 50 years and fell near the 65-70 LDN aircraft noise contours, making residential financing difficult. The court found that while a commercial rezone was possible long-term, it was not reasonably likely in the near future and would only have occurred due to the presence of the Third Runway.

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.
