Based on observstions during our site reconnaissance, and our <br />understanding that lhe proposed residence will have a�ninimum 60 foot setback from <br />the top of the steep slope, it is our opinion the site presents a relatively low hazard to the <br />proposed structure, provided the recommendations ir, this report 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 ;hat the proposed construction is to consist of a single family, one <br />story, modular residence, located near the central portion of the lot. The pruperty is <br />currently vacant. The topography at 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 adjacent properties to the north and south of <br />the subject lot have similar slope configurations. <br />Vegetation on the site co�sisted of mainly field grass and blackberry bushes. At the time <br />o� our visit, �ve did not observe obvious visual indications of slope instability, such as <br />fresh soil exposures. areas of hummocky topography, scarps, tension cracks, sag <br />ponds, excessively curved or knocked-o�sr tree trunks, or unexplainable vegetative <br />anomalies. <br />Subsurface Conditions <br />;;ring our site visit, we explored the subsurface soil conditions at two locations with a <br />, hber tired backhoe. Test pit 1(TP-1) was located at the west end of the residence <br />le TP-2 was at the east end. <br />ubsurface soil conditions at TP-1 consisted of approximately 1 foot of soft topsoil <br />�rierlying medium dense, silty sa�d with gravel (weathered glacial till). At a depth of 1.5 <br />icet below the existing surface, hard, very sandy, gravelly ciay (unweathered glacial till) <br />:.:�s encountered for the full depth of the test pit, 6 feet below the ground surface. At <br />I'-2, conditions were identical except the medium dense, silty sand extended 6 feet <br />Pac,e 1 of 5 <br />
