The building pad is stepped in the southwest corner and this portion is also covered with 6-inches of aggregate. In locations where trees and their roots were removed the aggregate is also thicker. Based on site testing and probing, the aggregate has been compacted to at least 95% of the matenals maximum dry density of 133.5 pet as determined by AASHTO T-99 method. The subgrade and aggregate fill are suitable for conventional residential style perimeter footing construction, We recommend that all footings be reinforced with at least two #4 steel reinforcing bars, and that surface water be directed away from the foundatIons and not allowed to pond adjacent to footings, We do not recommend allOWIng dump-trucks, concrete trucks or other heavy equipment onto the building pad during wet weather, Sincerely, Ford & Associates, Inc. 116Hwy 99N ,Sultel00.PO Box2273S.Eugene,OR97402.(S41)344-18S2.Fax(541)344_9923 E-mail mall@fnflncnet.Websltewwwfnflnc.net CertIfied WB E /0 B E
