    Multiple agency fiscal note summary: Transportation policy goals (HB 2688)

    House Bill 2688 proposes changes to Washington State's transportation system policy goals, requiring the Department of Transportation (WSDOT) to evaluate transportation projects submitted to the legislature using updated policy criteria. Multiple state agencies — including the Departments of Commerce, Health, Ecology, and the Interagency Council on Health Disparities — would be required to participate in these project evaluations, along with representatives from vulnerable and highly impacted communities. The fiscal impact on participating agencies is estimated to be non-zero but indeterminate, with the Department of Commerce alone estimating costs of between $21,000 and $35,000 per year.

    HB 2688 bill analysis: Expanding transportation policy goals

    Washington State House Bill 2688 proposes expanding and modifying the state's transportation policy goals by adding new priorities such as accessibility, health and resilience, and equity and environmental justice, while removing existing goals like mobility and stewardship. The bill would require all transportation projects to be evaluated against these updated goals and specific metrics before receiving budget authorization, with projects failing to meet a minimum score threshold being excluded from funding. The evaluation process would involve multiple state agencies and must include public input from vulnerable and highly impacted communities.

    House Bill No. 636: An act relating to aircraft noise abatement

    Washington State House Bill 636, passed by the House on February 21, 1979, and the Senate on March 2, 1979, amends state law relating to aircraft noise abatement near airports. The bill expands the geographic boundaries of 'impacted areas' around runways and prohibits port districts from undertaking noise abatement programs for property owners who have already been relocated under the same chapter. It was introduced by Representatives Charnley, Barnes, and Rohrbach during the 46th Legislature's Regular Session.

    House Bill No. 1191: An act relating to port district commissioners

    House Bill 1191, introduced in Washington State's 46th Legislature in 1979, proposed changes to how Port of Seattle commissioners are elected. The bill would put before voters a measure to elect three port commissioners from geographic commissioner districts and two additional commissioners chosen at large from the port district as a whole. It also established that in class AA counties with nine councilmanic districts, like Seattle, there would be three port commissioner districts each containing three councilmanic districts.

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.
