Mr. Joe Green <br />Preject No. EAIX-91-411 <br />Report No. 09-121-2123 <br />December 26, 1991 <br />Page 3 <br /> <br />! <br />] <br />I <br />I <br />I <br /> <br />Fill - Fill material consisting primarily of a <br />loose light brown to brown clayey silt to silt with <br />rock fragments and un-decomposed organic material <br />was encountered in all test explorations. This <br />unit extended to depths of 2 to 8.5 feet below <br />existing surface grade. The results of e×ploration <br />indicate that this unit was probably not placed ss <br />a structural engineered fill. <br /> <br />Sandy Silt - Two of the test explorations bottomed <br />in a moderately soft to firm light brown fire saDdy <br />silt at depths of 11.5 feet below existing surface <br />grade. <br /> <br />I <br />i <br />I <br /> <br />Silty sand - The remaining test e×plorations <br />bottomed in a firm to moderately dense light brown <br />silty very fine sand at a depth of 16.5 feet below <br />existing surface grade. The upper contact of this <br />unit was encountered at depths of 14.0 feet. <br /> <br />Groun4w~ter <br /> <br />Groundwater was not encountered within the borings <br />investigation. <br /> <br />Proposed Construction <br /> <br />of this <br /> <br />! <br />I <br /> <br />We understand that plans call for the construction of four <br />(4) mobile homes, to be developed one per each of the four <br />lots. We understand that the foundation system for each of <br />the homes is to be similar and will consist of some four (4) <br />6'* X 20" concrete runner pads. <br /> <br />,i <br /> <br /> <br />
