The purpose of our <br /> observation was to assist you in evaluating the potential impact of groundwater on the below <br /> grade foundation and provide recommendations to preclude basement water problems. <br /> DESIGN INFORMATION <br /> The proposed single family residence to be constructed is a two story home with poured <br /> foundation and an attached garage. The house dimensions are 50' x 30'. The lowest floor <br /> slab is at assumed elevation 100. We have assumed a 2,000 pound bearing capacity for this <br /> structure. <br /> SERVICES PERFORMED <br /> Our observation was conducted on May 17, 2006. At that time test pits were excavated in <br /> the area that the house will occupy. These test pits were approximately 3 feet below the <br /> existing grade. These test pits encountered 8 inches of soft, grey lean clay (CL) underlain <br /> with 2 1/2 feet of brown, medium dense, mottled, silty clayey sand (CL-ML). These silty <br /> soils were underlain with a grey, wet poorly graded sand (SP), and poorly graded sand with <br /> silt. Hand auger probes revealed these water bearing sands down to a termination depth of 5 <br />
