    Exhibit 228: NHC Letter to U.S. Army Corps of Engineers Identifying Port Of Seattle Document Inconsistencies in SMP and NRMP for Sea-Tac Airport Master Plan Update

    A December 2001 technical letter from Northwest Hydraulic Consultants, written on behalf of the Airport Communities Coalition, identifies inconsistencies in the Port of Seattle's stormwater management plans for Sea-Tac Airport expansion. The letter argues that the Port's hydrologic modeling failed to account for the planned commercial redevelopment of borrow pit areas by 2006, and that the Natural Resource Mitigation Plan reverted to an outdated stormwater approach relying on regional detention facilities to be built by others. These gaps, the consultants contend, prevent a full assessment of the airport Master Plan Update's environmental impacts.

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.
