�' <br />, <br />r <br />Gecuechnical Engineering Report <br />Kvemmo Singie-Family Residence <br />4003 Nassau Place, Everett <br />September 17, 2002 <br />NGA File No. 356102 <br />Page 2 <br />and provide specific geotechnical engineering recommendations for stabilizing the on site fill and <br />supporting the residence on pin piles. <br />For the purpose of completing this study, we have been provided with preliminary foundation deteils and <br />a facsimile copy of an undated site plan prepared by JWS Design. We have also been provided with a <br />cross section of the residence and four preliminary foundat:on details indicating that pilings will bc used <br />for the foundation. <br />SCOPE <br />The purpose of this study is to explore and characterize the site subsurface conditions, and provide <br />recommendations for site devel�pment. Specifically, our scope of services includes the following items: <br />2. <br />3. <br />4. <br />5. <br />6. <br />7. <br />8. <br />Revie�v available soils and geologic maps ofthe area. <br />Explore the site with a track-mounted drill rig to characterize subsurface soil and ground <br />water conditions. Drill �ig contracted by you. <br />Perform a stability analysis of the existing fill. <br />Provide recommendations fcr foundation design, including lateral soil loads and bearing <br />capacity, and a deep foundation system, if necessary. <br />Provide recommendations for general eaithwork, including cuts and fills. <br />Provide recommendations for site c}rainage. <br />Provide recommendations for erosion conuol. <br />Prepare a geotechnical report to document our findings and recommendations. <br />SITE CONDITIONS <br />Surface <br />The iot is a rectangular-shaped parcel approximately 0.2 acres in size. The site rieasures approximately <br />145 feet in the east to west direction and 60 feet in the north to south direction. Nassau Place borders the <br />site on the west side. Residences border the site to the north, south, and east. A 30-foot wide utility <br />easement exists withir. the eastem portion of the site. We understand that a sewer line exists within ]0 <br />feet or so of the westem easement boundary. <br />( The ground surface throughout most of the site generally slopes gently to moderately down to the east. <br />Straw had been sprcad across the site at the time of our field reconnaissance, end other areas of the site <br />� <br />NELSON GEOTECHNICAL ASSOCIATES, INC <br />�'1�' <br />
