Recommended that east side perimeter footings be additional excavated by approx. 1' to provide 5-feet of horizontal offset between the edge of the footing and free face of the slope. Based on probe resistance,we recommended additional excavations of soft subgrade areas ranging from 6"to 12"BGS today(see site plan and below for details).After additional excavation, I re-evaluated the subgrade and observed the subgrade to generally be stiff to medium stiff. Lot 179 Additional excavation observed today; • 7'x2'x6" • 15'x2'x10" Lot 178 Additional excavation observed today; • 13'x2'x12" • 10'x2'x6" • 20'x2'x12" Lot 177 Additional excavation observed today; which caves into • 16'x2'xi 2" overexcavated footing • 10'x2'x8" subgrades • 20'x2'x6" I observed that due to wet weather,there was free standing water n the surface of the footing subgrade. Recommend footings be de-watered and any saturated/loose soil a removed f before pouring footing. Recommend that time be limited in which footing subgrade is left exposed. Based on our observations and probing, it is our opinion that subgrade observed today(contingent on following recommendations noted above),where observed today and indicated on attached site plan, have been prepared in general accordance with our geotechnical recommendations. 9450 SW Commerce Circle,Suite 300 I Wilsonville,OR 97070 1503.968.8787 I www.geodesigninc.com
