This King County map, dated March 15, 2004, identifies Walker Basin environmental projects including Estuary Improvements, Headwater Wetland Purchase and Protection, and Guardrail Painting. The map highlights key natural features such as lakes, ponds, streams, creeks, and wetlands within the Walker Basin boundary. Projects are categorized by type, including habitat and water quality initiatives, and are plotted against major streets and waterways in the area.

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.

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.

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.

HartCrowser presentation on embankment infiltration and seepage modeling, covering seepage modeling using HELP (Hydrologic Evaluation of Landfill Performance), precipitation components including runoff, infiltration, and seepage, seepage through embankment flow in drain layer, deep percolation below drain, groundwater flow laterally in subgrade, and deep percolation through underlying till/clay. Includes embankment slope section diagram showing seepage parameters

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.

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.
