    Miller, Walker, and Salmon Creek Basin Plan second public meeting comment request form

    This is a public comment form from a March 11, 2004 King County meeting about the Miller, Walker, and Salmon Creek Basin Plan, asking residents for input on salmon restoration efforts and environmental priorities. The form poses questions about whether it is worthwhile to restore fish runs in Salmon Creek given no fish have been seen for roughly 20 years, and how to prioritize restoration of Lake Hicks and related projects. It also asks residents how much they would be willing to contribute through increased taxes and fees to fund these efforts.

    Miller and Walker Basins: Parcels likely to redevelop

    This King County map, dated March 9, 2004, identifies parcels within the Miller and Walker Basins that are likely to redevelop based on land and improvement values. It highlights features such as lakes, ponds, rivers, streams, and wetlands alongside redevelopment-candidate parcels marked in red. The map was produced by King County staff using data from multiple sources and is intended to support land use planning in these two drainage basins.

    Walker Creek Basin potential water quality regulatory areas

    This King County map, dated December 8, 2003, identifies Potential Water Quality Regulatory Areas within the Walker Creek Basin, highlighting features such as streams, lakes and ponds, wetlands, potentially regulated parcels, and potentially regulated roads. The map was compiled by King County staff to support water quality planning and regulation in the basin. Note that while this document relates to King County environmental planning, it does not directly address Sea-Tac Airport noise policy.

    EXH AR026434: Highway Runoff Chemistry Hydrology Residence Time Non-Equilibrium Partitioning Heavy Metals Treatment

    This research study examines how heavy metals in highway stormwater runoff behave as water flows off pavement, finding that most heavy metals remain dissolved rather than attaching to solid particles due to low alkalinity and short travel times on the pavement surface. The study, conducted on Interstate 75 in Cincinnati over two years, explores how best management practices like detention basins or infiltration trenches could be used to capture these metals before they reach receiving waters.

    EXH AR026409: Wetland Mitigation Calculations — Vacca Farm

    This document outlines wetland mitigation calculations for the Vacca Farm site, detailing compensation actions such as wetland restoration and enhancement across various locations including Lora Lake and prior converted croplands. Adjustments were made to credit acreages based on state ecology findings and documentation gaps; for example, the 6.60-acre converted cropland credit was reduced to 3.30 acres because the state identified those areas as existing wetlands requiring enhancement ratios rather than restoration ratios. In total, the site's original 10.48 credit acres were adjusted down to 5.61 acres after accounting for these regulatory and documentation considerations.

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.

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.
