Mass Gradine Trending generally north to south, the earthwork contractor continued mass grading processes over the project's furmer sludge disposal area near the south end of Pacific Topsoil's Smith Island Facility. Utilizing a large vibratory roller, the contractor compacted a I' loose lift of recently placed/aerated fill from construction sites in Mercer Island and Ballard. The combined soils (brown to orangish brown silty SAND with little gravel and trace deleterious debris) was compacted in a series of 4 passes and proved unyielding under'.he wheel weight of numerous truck/hailer assemblies. Further, the compacted soil was probed, with the full weight of the observer on a .5" diameter steel T-probe, and proved Gan with corresponding'i'-probe depths not exceeding 2". The contractor noted that the above fill was at/near the proposed finish grade for the protective layer. Additionally, AESI naed that the contractor had continued importing and spreading an approximately 8" layer of 2" minus crushed recycle near the west central margins of the site. As noted prior by the contractor, this material will be used to construct an E-W access road. See figure I for specific task location. Drainn ,e Per plan and prior to arrival, the contractor began construction on a perimeter drainage ditch for the fill area. Utilizing a large (tack hoe, the contractor removed approximately.5-l' of"protective Iaycr' soils (generally brown to grayish brown silty SAND with few gravels) along the perimeter of the fill area and sloped the ac�jacent sides of the ditch via bucket healing processes. Further, the contractor noted that he had installed two 12" ADS culvert pipes on lire north perimeter in nit effort to allow for access road construction without blocking flow in the ditch line. See figure I for specific task location. COP]FS TO: Distribution FIELD REP.: Jon D. Hansen, Sr Staff Geologist DATE SEP 2 3 2011 PRINCIPAL / PM: Jon Sondergaani, P.E.G MAILED:
