pAYID L. NELSON AND ASSOCIATES, IN�. <br /> Consulting Enginecring Geology <br /> September 28, 1984 <br /> • Project No. 7884 <br /> ?age four <br /> a potential perched wai�er condition within this area. It appears <br /> that the ground watar within this area is derived from on-site <br /> or fron� nearby areas, and could be controlled. Surface water <br /> areas were observed within the 5ite area. Generally, �ihese <br /> consist of local low spots within the area where suz•face water <br /> is allowed to pond, and due to the fine grained nature of the <br /> site soils, does not readily percolate into the subgrade soils . <br /> Conclusions � <br /> Based upon our investigation performed within the site area and <br /> past experience within the area, we believe �hat the site can be <br /> developed as anticipated, provide� that recommendations as pre- '� <br /> i <br /> sented herein are utilized for construction. <br /> Recommendations <br /> Site development within the proposed building areas should be <br /> performed such that building foundations are placed into the <br /> medium dense to dense weathered glacial eoils or the dense <br /> glacial sozls. We anticipate that foundations for the large <br /> three store building within the north portion of the site can <br /> be placed within the glacial soils below the loose surficial <br /> soils approximately j' to 4' below grade . Foundations could <br /> consist of continuous or spread type :�ootings placed within the I <br /> dense natural� soils which are clean, dry and compact. Pootings ', <br /> should be placed a minimum of 18" beiow finish grade as to be <br /> below fros+. level. Any loosened or wet s�ils should be removed <br /> from the footing excavation prior to placement of footing concrete . <br /> Anticipated maximum allowable soil pressures of 4000 pounds per <br /> square foot (psf) should te utilized for foundations placed as <br /> specified. The central retail building within the area of TB-4 <br /> and TB-5 should ariticipate foundation preparation and soil <br /> bearing loads as specified abo�re . Slab-on-grade preparation <br /> within these building areas should anticipate removal of the <br /> surficial organic topsoil and fill , compaction of the subgrade <br /> . • � <br /> � <br /> i <br /> I <br /> � <br /> � <br /> I <br />
