The purposes of this investigation were to <br />evaluate the subsurface conditions at the area of proposed construction and to provide <br />recommendations pertinent to grading, foundation design and other relevant parameters. <br />1.2 Scope of Services <br />Our scope of services included: <br />• Review of available soil and geologic data of the area. <br />• Logging and sampling of hand auger boring to a maximum depth of 5 feet below the <br />existing ground surface. Boring logs are presented in Appendix “A” (Field Investigation). <br />• Laboratory testing of representative samples collected from the proposed construction <br />area to establish engineering characteristics of the on-site soils. The laboratory test results are <br />presented in Appendix B (Laboratory Testing) and on the boring logs (Appendix A). <br />• Engineering analyses of the geotechnical data obtained from our background studies, <br />field investigation, and laboratory testing. <br />• Preparation of this report presenting our findings, conclusions, and recommendations <br />for the proposed development. <br /> <br />1.3 Proposed Construction <br />It is anticipated that the proposed construction is a new ADU residential with a one-story house <br />in the rear of lot site and room addition at right side of existing house. The structure of the <br />proposed residential building is anticipated to be one story in height. Column loads are be light. <br />Final grade is anticipated to be near the existing grade. <br />1.4 Site Conditions <br />The subject site is located at South side of Strawberry Ln, North of Westminster Ave., East of <br />Harbor Blvd, West of Fairview st., South of Trash st.. within a fully development area. <br /> <br />An existing one story house with typical concrete driveway, sidewalks, rear yard. <br /> <br />The subject site is relatively flat and is currently occupied by a residential house and a garage. <br />No major surface erosions were observed at the time of our field investigation. <br />2726 W Strawberry Ln & <br />Unit# 23/17/2025
