    Rising to recovery

    A September 2020 presentation by Port of Seattle Commissioner Ryan Calkins outlines the severe financial impact of the COVID-19 pandemic on the Port's operations, including a 75% drop in airport passengers, a 17% decline in seaport cargo activity, and a complete 100% halt in cruise traffic compared to July 2019. The Seattle-Tacoma International Airport (SEA) was projected to handle only around 20 million passengers in 2020, down sharply from a record 51.8 million in 2019. The presentation also provides historical context by comparing the 2020 downturn to previous industry shocks such as the 9/11 attacks and the Great Recession, both of which the airport ultimately recovered from.

    Briefing on the tax levy and draft plan of finance for 2019-2023

    In November 2018, the Port of Seattle Commission received a briefing on the proposed tax levy and five-year Capital Improvement Plan (CIP) financing for 2019–2023. Staff recommended increasing the property tax levy from $72 million to $74.16 million (a 3% rise) to cover funding gaps in Maritime, Economic Development, and Northwest Seaport Alliance projects, even after deferring certain capital projects. The Airport division was noted as a self-funding enterprise with its own separate financing plan.

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.
