GeoTest Services, Inc. October 8, 2021 <br /> 2405 Hillside Lane, Everett, WA Project No. 21-0845 <br /> , Emir <br /> very fine sand with some lenses of gravel and peat. The depositional environments associated <br /> with Transitional Beds are hypothesized to be that of glaciolacustrine and glaciofluvial deposits, <br /> mostly prior to glacial advance southward. <br /> Our on-site explorations indicate that the encountered subsurface soil conditions are generally <br /> iin accordance with the mapped Fraser to Pre-Fraser Transitional Beds (QTb). <br /> .`.°']VAS • • v*: `,� •,e <br /> • <br /> Alb: Viliii.$. <br /> 'R i a .. ♦ t ��. %, - , _ i. .tc' ,�� .,!,Yam^ .` t •+4,, ' <br /> .

Perched groundwater seepage should be anticipated during the wet <br /> season or after long periods of precipitation,atop the low-permeability Transitional Bed soils that <br /> were found at depth. <br /> The groundwater conditions reported on the exploration logs are for the specific locations and <br /> dates indicated, and therefore may not be indicative of other locations and/or times. <br /> 4 <br />
