    Port Of Seattle Hardship Acquisition Committee recommendations: Mrs. Carrie Cochrane, Parcel A-447

    At a June 5, 1979 meeting, the Port of Seattle Hardship Acquisition Committee unanimously recommended the early purchase of Parcel A-447, owned by Mrs. Carrie Cochrane, under special hardship acquisition criteria.

The recommendation was signed by Committee Chairperson W. Thomas Ruttkay on July 20, 1979.

    Citizens Advisory Committee Recommendation on Application for Hardship – Z-685 Tom Fest

    In April 1979, the Citizens Advisory Committee recommended that the Port of Seattle pursue early acquisition of a property owned by Tom Fest (parcel Z-685) under hardship status. The Committee determined that a quick purchase would benefit both parties, urging the Port to promptly establish a fair price and the owner to sell the property as a single parcel rather than subdividing it into three lots. The recommendation also specified that the owner should not be required to pay sewer hook-up costs before the sale unless the Port agreed to them.

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.
