Based on observations diiring our site reconnaissance, and our <br />understanding that the proposed residence will have a minimum 60 foot setback from <br />the top of the steep slope, it is our opinion the sile presents : relatively low hazard to the <br />proposed structure, provided 1he recommendalions in this �eport are followed. <br />Site Observations <br />The subject property is located on the west side of Larimer Road in Everett, Washington. <br />It is our understanding that the proposed construction is ro consist of a single family, one <br />story, moduiar residence, Iocated near the cenlral portion of [he lot. The property is <br />currently vacant. The topography al the site dips to the east at an inclination from <br />approximately 15° to 20° for about 170 feet and then descends to Larimer Road at an <br />inclination of 45° for 20 vertical feet. The adjacenl properties to the north and south of <br />the subject lot have similar slope configurations. <br />Vegetation on [he site consisted of mainly field grass and blackberry blshes. A[ the time <br />of our visit, we did not observe obvious visuai indications of slope instability, such as <br />fresh soil exposures, areas of hummocky topography, scarps, tension cracks, say <br />ponds, excessively curved or knocked-over lree Vunks, or unexplainable vagetative <br />anomalies. <br />Subsurface Condit�ons <br />During our sile visit, we explored lhe subsurface soil conditions at lwo localions �vith a <br />rubber lired backhoe. Test pit �(TP-1) �-as located at the west end of the residence <br />while TP-2 was at the east end. <br />Suhsurface soil conditions at TP-1 consisted of approximately 1 foot of sofi topsoil <br />overlying medium dense, silty sand with gravel (weathered glacial till). At a deplh of 1.5 <br />feet below the existing sur�ace, hard, very sandy, gravelly clay (unweathered c�lacial till) <br />was encountered for the full depth of the test pit, 6 feet below tne ground surface. At <br />TP-2, conditions were identical except the medium dense, silty sand extended 6 feet <br />?age 1 of 5 <br />� � � �� <br />
