Mass Cradbull 'rorAvx Trending generally east to west, the earthwork contractor continued mass grading processes over the IBsfjrst�s sludge disposal area near the south end of Pacific Topsoil's Smith Island Facility. Utilizing a large dozer (D6), the contractor spread/aerated recently placed stockpiled imported soils from the Highway 9 widening site (bluish gray SILT to brownish gray silty SAND with few gravels) into an approximately .5' loose lift and compacted the material, in a series of passes, via large vibratory roller. The compacted material was observed 10 be unyielding tinder file continued wheel weight of Inlckhrailer assemblies. Further, the compacted soil was probed, with the full weight of the observer on a .5" diameter steel T-probe, and proved firm/unyicli ing with average penetrations of 2". A series of in place density tests were conducted to confirm the specified minimum compaction (95% ASTM 1557). The contractor was notified of all density insults listed below. The contractor noted Thal soil from a Mercer Island site was continuing to be imported and stockpiled near the western margins of the property. Further, the contractor noted that both the roller and dozer had broken down earlier in the day and that they had onlyjust begun to spread and compact several areas along the southern margins of the property.
