X <br />Nr <br />L <br />nage E - *120 86-74 <br />beyond the edges of the footings a distance nual to the depth of compacted <br />fill beneath the footings. This fill should be compacted to 95% of standard <br />Proctor density. We recommend designing the foundations for a maximum <br />loading of 1500 psf (pounds per square foot). in our opinion, the soils <br />will provide a factor of safety of at IeLst three against an actual shear <br />failure. We estimate total settlement will t2 up to 1" ane differential <br />settlement possibly uo to 3/4". Because the underlyinq natural soils are some- <br />what erratic. we recnmmend providing a fairly rigid foundation to minimize <br />the effects of differential settlement. <br />The present water level is only about 4' below grade. In some areas, the <br />excavation will extend below the present water level. If at all possible, <br />the excavation should be dewatered so that the soils cin be observed prior <br />to placing the controlled fill. All fill placed below the present water <br />level should consist of relatively clean sand with less than 10% passing <br />a &200 sieve. <br />In the garage area, the topsoil should be rer..oved and replaced with controlled <br />compacted fill. We recommend all fill placed in the garage area consist of <br />a relatively clean sand with less than 10% passing a *200 sieve. <br />SITE OBSERVATION <br />We recommend that the excavation be observed by a soil engineer prior to the <br />placement of foundations or controlled fill. We also recommend that density <br />soa expu3p ion <br />
