    Public hearing for Des Moines Creek Business Park West: Declaring Tract C surplus, approving Purchase and Sale Agreement and approving Trail Easement

    The Des Moines, WA City Council held a public hearing on September 12, 2024 to consider selling a small city-owned parcel called 'Tract C' (19,881 sq ft) to the Port of Seattle for $690,000, its appraised fair market value, to support truck access for the Des Moines Creek Business Park West development near Seattle-Tacoma International Airport. The sale is part of a long-running effort to develop commercial and industrial land on Port-owned property, with the project expected to support over 600 full-time jobs. The council also considered accepting a trail easement from the Port to connect the Barnes Creek Trail to the Des Moines Creek Trail as part of the same development agreement.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation.
