i SHANNON F�WILSON,INC. I would be required in building areas, as these soils may not prwide suitable foundadon Isupport for footings and floor slabs. Fill soils should be strippad because they were observed to contain wood debris and other organic and deleterious materials and there is no idocumentation of compacdve effort. Also, Sll cavers up to 24 inches of original oiganic- rich wpsoil materials in a number of explorations. Both wndidons could cause lacger than I expected settlements of footings or slabs. Additionally, based on our experience on similaz sibes, it is our opinion that at least a portion of the weathered nadve soils will have ro be removed, as these soils were generally loose and wet. It may be possible to stabilize the Ilrnver 1 faot of these soils by aeretion or cement/lime modification. However, if the dme frdme for construction is such that scarificadon, aera6on, or soil modifica6on is not Ipossible, it should be ezpected that all of this material will have to be remvved, as it is easily disturbed and cannot be adequately proof-m11ed or compacted in place. Additionally, � because the building will be constructed partially in cut and partially in fill materials, the I possibility of sharp, differendal settlement will increase if soft soils are left beneath the I building. Estimated depths to glacial soils (assuming all weathered native soils aze remaved) are indicated on Figure 1. IAs shown on Figure 1, the total depth of stripping and wereaccavation is an6cipated less than 3 feet for most areas. However, two areas of deep, unsuihable soils Iwere observed in our explordtions. The first area is in the southeast wrner of the site near the stockpiled soils. Fill depths aze expected W be as great as 12 feet belaw ground sudace (greater when wnsidering the depths from the top of the stockpiles in the area). However, we understand that 20-foot cuts are planned in the area as part of site devclopment, such that I all fill materials would be remwed by the time the final grdde is reached. The second area of deep, unsuihable soils is in the southwest corner of the site where no development is Iplanned. Therefore, stripping and werexcavation would not be required he�e. As part of development by the previous owner, a number of wetlands we�e Ifilled and Narbeck Creek relocated. We recommend that, if possible, the original locations of the wetland and the creek be identified, since these areas would probably contain loose, � soft, organic, or otherwise unsuitable soils. Should such areas be identi6ed during site preparation to lie within the proposed building areas, they would nced to be werexcavated I and replaced wiih compacted sWctural fill. Should such amas lie within the proposed par!dng and drive areas, they would nced to be proof-mlled and checked for the presence of I W-6693-01 16 �
