• � Paga Four <br /> � <br /> 1 : This area haa the mor�holoqy of the toa of a alump deposit. <br /> A cluster �f younq red alder indicat• tha epproximata time <br /> of mov�mant to be s 15-20 years ago. Pieces of glase were found <br /> � at depth in teat hole �ix, and no veathared soil horizons were <br /> ::oted. No larqe trees or stumps were locatad immediately above <br /> this vicinity. <br /> �: A biglsaf mapla trae ia bowed aeverely at the baae, indicating <br /> aoil craep. ' . <br /> 3: A concrete alab has tilted downslope at this location. <br /> 4: A concreta block well haa deformed at this location, rotatinq <br /> downslope from tha top. � <br /> A raqional invastiqation of the aideslope indicated that no larqe <br /> displacement alides or debrie flow deposits are preaent. <br /> The 50 year res'_dent of 2601 Grand Ave has a dry full basement, <br /> and reports no alides during that period. <br /> The reeident two houses to the north reported that fill was side- <br /> cnst for yard aome 60 years aqo, however test hole 3 encountered <br /> netive aoils on the project site. ' <br /> A larqe anag in qrowth poaition indicatea atability for a period <br /> of time below tha toe of ai8ecast' fill. <br /> Conclusions and Recommendations: <br /> It is our opinion that the site can be developed within the pAram- <br /> etars described harein without incurrinq mass movement of the side- <br /> slope; provided. that the setback delineated on the attached map <br /> page !s observed; and that dreinaqe from impervious areas is con- <br /> veyed away from the sideslope. <br /> If footing .drains cannot be discharged into the street or storm <br /> sewer, a tiqhtline should be designed to daylight at the 60 ft. <br /> contour. <br /> o fill, storm water, heavy machinery or other disturbance can <br /> e placed east of the buildinq setback line. No material can be . <br /> emoved from the base of the slope. <br /> onventional footings placed to bear on the encountered gravelly <br /> andy loam can be assiqnad e soil bearing pressure of 2,000 P.S.F. <br /> safe allowable soil bearinq pressuze of 3,500 P.S.F. can be <br /> ssiqned the lodgament till. All footing excevations should be <br /> leared of slouqhed or water loosened material and. probed for <br /> oose areas prior to pouring concrete. <br /> dditional Comments : I <br /> EA�77JI a,V•1[YS/S .-'/ <br /> - - - -------- ■ <br />
