    Ombudsman Letter to Messrs. Stockdale and Sutter Regarding DesMoines Sewer District Connection

    A March 1979 letter from Deputy Ombudsman Rella E. Foley to Messrs. Stockdale and Sutter details the financial hardship of a Mr. Fest, whose annual income of approximately $6,000 makes it impossible for him to afford sewer connection payments. Foley recommends that the DesMoines Sewer District allow Mr. Fest a temporary sewer connection while the Port of Seattle moves quickly to acquire his property, noting that delays forcing him to pursue a short plat subdivision would ultimately cost taxpayers more. The letter was copied to legal counsel for both the DesMoines Sewer District and the Port of Seattle.

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.
