Box 495 <br />Stanwood, Washington <br />9B292 <br />Attention: Mr. Bob Reed <br />Reference: Fleming St. Duplex. <br />Fleming Street <br />Everett, Washington <br />Dear Mr. Reed: <br />On April 3, 19B5, an engineering geolocist from our firm witnessed the <br />excavation of two backhoe test pits at the above referenced project site. <br />The purpose of the test holes was to determine the depth to natural soils <br />suitable for support of the proposed duplex. The duplex will be <br />constructed of wood framing with a concrete slab on grade lower floor. We <br />understand that the site will be lowered approximately three (3) feet in <br />order to establish the proposed slab elevation. <br />Site Description <br />The building site is located at within the 5900 block of Fleming Street, on <br />the west side of the street, in Everett, Washington. Prior to our site <br />visit, a portion of the building area had been excavated to expose the <br />underlying natural sandy soils. This excavation work was concentrated <br />over the northern part of the site. The excess material from the cut was <br />stockpiled along the southern portions of the building area. <br />We understand that prior to your work at this site, fill material was pushed <br />out over the southerly slope. It is apparent that the much of the brush, <br />stumps and downed trees were not removed before the fill was placed. Small <br />settlement cracks were observed within this older fill material near the <br />top of the slope. <br />Subsurface Soils and Ground Water <br />The natural soils underlying this site are composed of gravelly sands with <br />minor silt. These soils are exposed within the northern cut and were <br />observed within our test pits approximately two (2) feet below existing <br />qrade at the southwest and southeast building corners. The material <br />overlying the natural soil is a fill material composed of a gravelly sand <br />with some silt. <br />No subsurface seepages were observed within our test pit excavations. <br />However, along the western cut face near the northwest corner of the site, <br />surficial erosion from a small seep was noted. You stated that the light <br />seep appears to have come from drainage out of a septic drainfield due to the <br />odor. We further noted that the water has softened the soils at the base of <br />
