Mass Gradine 'trending generally north to south, the earthwork contractor continued mass grading processes for the project's proposer) sludge disposal area near the south end of Pacific Topsoil's Smith Island Facility. Utilizing a large dozer (DO), the contractor spread recently placed/stockpiled imported soils from the I lighway 9 widening site (bluish gray SILT to brownish gray silty SAND with few gravels) into Jo approxinntcly S-I' loose lift and compacted the material via large vibratory roller. The compacted material was observed to be unyielding under the continued wheel weight of truck/traile, assemblies. Further, the compacted soil was probed, with the full weight of the observer on n .5" diameter steel T-probe, and proved fim✓unyielding with average penetrations of I". A series of in place density tests were conducted to confirm the specilied minimum compaction (95%AS'I'M 1557). 'Ilse contractor was notified of all density results listed below. The contractor noted that some :veils of fill to the immediate south appeared wcl upon import. 'Iliese areas, the contractor noted, would be further acraled to m/near optimum omiSnvc condition before being compacted. See figure 1 for specific tusk location.
