CASGAOE TE5TING LABORPTOiiV� INC. <br /> I � Mr, John Piazza <br /> March 4,� 1976 <br /> Page 3 <br /> should be accomplished prior to backfilli�ig and compacting in <br /> the trench to the required 95� density. Footings then may be <br /> constructed on the foundation trench fill with maximum soil pres- <br /> sure of 1, 500 p.s. f. after certification of the requir�d density. <br /> We suggest that no construction be attempted on the slope-filled <br /> area. This area is considered unstable due to the slope fill and <br /> further soils inves*igations will be required to determine stabil- <br /> ity for construction. <br /> Thank ou for this opportunity to be of service.
