    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.

    Chapter 53.54 RCW: Aircraft noise abatement

    Chapter 53.54 RCW authorizes Washington port districts operating large airports (such as Sea-Tac) to carry out programs that reduce the impact of jet aircraft noise on surrounding neighborhoods, including purchasing properties, providing soundproofing, and offering transaction assistance to affected homeowners. The law defines 'impacted areas' with specific distance limits from runways and allows properties within those boundaries to receive noise mitigation benefits. Recent 2024 updates expand the program to allow inspection, repair, or replacement of previously installed noise mitigation equipment that is no longer working as intended or has caused structural damage.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

Read This!

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. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
