    Airport Dining and Retail tenant reimbursement request and lease amendment for SP-LW LLC

    The Port of Seattle requested Commission approval to reimburse airport tenant SP-LW LLC (Sub Pop-Li'l Woody's) up to $360,095.72 for design costs after it was discovered that a required grease waste line could not be installed at their originally awarded Concourse C restaurant space (CC-06) due to building code constraints. As a resolution, the Port proposed moving the tenant to a comparable space in the North Satellite (NS-23) and amending their lease accordingly, with no changes to concession fees. The situation also prompted the Port to establish new planning protocols to verify utility infrastructure viability before awarding future food and beverage spaces.

    JO7110.693 Simultaneous dependent and independent parallel approach operations

    This FAA notice (effective August 2015) updates the rules for how air traffic controllers manage aircraft making simultaneous approaches to parallel runways. It introduces new diagonal radar separation distances between aircraft based on how far apart the runway centerlines are, ranging from 1 mile of separation for runways 2,500–3,600 feet apart to 2 miles for runways 4,301–9,000 feet apart. While focused on controller procedures rather than noise policy directly, these standards govern how closely aircraft can be spaced during parallel runway approaches, which is relevant to arrival patterns affecting communities near airports like Sea-Tac.

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.
