No. 853-13G Mr. Jim Hesseltine P.O. Box 615 Snohomish, WA 98290 Reference: Hesseltine Property 5829 Fleming Street Everett, Washington Dear Mr. Hesseltine: On March 20, 1985 a geologist from Cascade Geotechnical visited the above referenced site in order to conduct a study to determine the type, depth and condition of the existing sub surface soils. Three tests pits were dug using a self propelled backhoe. These test pits .were located near the southeast corner, northeast corner and midpoint of the west wall of the proposed building. P. maximum excavation depth of thirteen and one-half (13 1/2) feet belo%. exist- ing grade was achieved in the southeast corner pit. In all three of the test pits a light gray gravelly silty sand with construction rubble was found from the surface to a depth ranging from two (2) feet (TP-3) to eleven (11) feet (TP-1)below existing grades. This light gray soil layer is old dill. This fill unit is underlain by a layer of highly organic silty sand, that ranges in thickness from one-half (1/2) to three-quarters (3/4) of a foot thick. Underlaying the organic layer was a reddish brown silty sand. This material is the native soil and is of undetermined thickness. No ground water seepage was encountered in any of: the test pit excavations. From our findings we have determined that the fill found across the site may be suitable for carrying structural loads. However, since we have no way of knowing how well the fill was compacted during placement we can not accurately determine the potential for differ-
