Variable Very soft to stiff or very loose to dense Density/ Hardness Strength Permeability Liquefaction Potential b Potentially low Variable Potentially high Wetland (Qw) Mass wastage (Qmw) Landslide (Qls) Tideflat (Qtf) Lake (Ql) Vashon recessional outwash () Vashon recessional lacustrine (l) Organic-rich sediment, peat, and fine-grained alluvium, poorly drained and intermittently wet. Not all have been mapped. Colluvium, soil, landslide debris, and organic matter. Common below springs where peaty are also present. Mapped on steep slopes. Deposits, both mapped and unmapped, include abundant landslides up to 500 feet long. Blocks of surficial transported downslope en masse by gravity. Numerous unmapped areas of both landslide and related mass-wastage occur along slopes. Landslide terrain often includes benches that slope back into the hillside and have wetlands and peat. Silt, sand, organic sediment, and detritus, with some shells, historically exposed in broad coastal benches at low tide and now covered with fill. Silt and clay with local sand layers, peat, and other organic sediments deposited into Lake Washington. Most mapped areas are lake bottom sediments exposed when Lake Washington was lowered in At many locations, the lake are thin and overlie a dense substrate. Commonly capped by fill to improve building sites. Layered sand and gravel. Deposited in outwash channels of melting glaciers during the ice retreat. Also includes that accumulated in or adjacent to recessional lakes. Deposits less than about 3 feet thick not shown on map. Thinly layered silt and clay with local sand layers, peat, and other organic sediments, deposited in slow-flowing water and temporary lakes. Low Very soft to medium stiff or very loose to medium dense Low Loose to dense and soft to stiff; variable degree of consolidation depends on material in colluvium and its coherency Low Very loose to very dense or soft to hard; variable degree of consolidation depends on material coherency Low Very loose to dense or very soft to stiff Low Very soft to medium stiff or very loose to medium dense Potentially low Potentially low Potentially low Potentially low Potentially low Medium Loose to dense Low t o medium Variable Potentially high Variable Potentially high Variable Potentially high Variable Potentially high Low Potentially high Low Potentially high Low to medium Very soft to stiff Medium Low Medium Draft EIS F December 2008

Contains layers of sand and gravel and cobbles are common. Upper 3 feet of till generally weathered and only medium dense to dense. Sand and gravel deposited by streams from advancing ice sheet. Silt lenses locally present in upper part and are common in lower part. Thinly layered to a mixture of silt and clay with scattered pebbles deposited in lowland proglacial lakes. Layers of sand, gravel, and silt, with and mixtures. Locally divided into: Coarse grained (c) Sand and gravel, clean to silty, with some silt layers. Fine grained (f) Silt and clay, may have sand layers.

High Hard High Low Low (Qpogf) Deposits of Till-like material, but finer grained and with fewer gravel. High Very dense High Low Low and hard age, glacial diamict (Qpogd) Deposits of Sand, gravel, silt, clay, and organic. High Very dense High Low Low and hard age nonglacial () Deposits of Silt and clay, may have sand layers and peat. High Hard High Low Low age finegrained nonglacial (f) a Areas mapped as artificial fill are locations where fill placement is relatively extensive and is likely to be thick enough to be of geotechnical significance (greater than about 6.5 feet thick). Liquefaction depends in part on density of the material and the groundwater table elevation. These ratings assume a shallow groundwater condition. High strength unless cut vertically below the water table, then potentially low to medium strength. b c Notes: The descriptions and density/hardness are based on the following sources: Troost et al. (2005), Troost and Wisher (2006). The terms low, medium, and high were determined based on professional opinion from experience with the soil types. Hazard susceptibility was determined based on criteria in the cities of Seattle, Bellevue, and Redmond Code; King County Code; and professional opinion. Draft EIS F December 2008
