Results of our evaluation and design recommendations are described below. <br /> PROJECT INFORMATION <br /> The site is located as shown in Figure 1 and Figure 2. The site is a developed lot covered with a <br /> residential building in a residential neighborhood. Site topography is illustrated in Figure 1. We <br /> understand the garage foundations will be supported/underpinned on helical piers or steel pipe <br /> piles. We do not anticipate significant site grading (fill placement)for this project. We anticipate <br /> proposed underpinnings or foundation stabilization elements will be constructed with moderate <br /> foundation loads. If these proposed conditions change, we should be contacted to modify our <br /> report. It should be noted that our scope of services did not include any structural design or <br /> foundation engineering of any kind. Our scope of services did not include forensic evaluation or <br /> condition survey of the existing structures on the site. Our scope of work was limited to <br /> geotechnical evaluation for the use of helical piers for supporting the proposed deck foundations. <br /> SCOPE OF WORK <br /> Our scope of work included following specific items: <br /> • Review of available reports and literature on soils, geology, natural hazards, and USGS maps. <br /> • Surface and subsurface soils/bedrock and groundwater/drainage conditions using soil <br /> auguring and Williamson drive probes. We performed two soil borings/explorations/drive <br /> 41105 NE Cedar Ridge Rd www.americangeoservices.com Mailing: 24 Roy Street #343 <br /> Amboy, WA 98601 sma@americangeoservices.com Seattle, WA 98109 <br /> Ph: (360) 437 16369 Ph: (888) 276 4027 P .
