Box 476 <br />Lake Stevens, Washington 98258 <br />Subject: Confirmation of Bearing Soil <br />Comer Lot - Olive St. & Temple Drive <br />Everett, Washington <br />Dear Dennis; <br />As requested an engineering geologist from GES, Inc. visited the above referenced site <br />June 4,7,8,10 and 11, 1993 to confirm bearing soil for foundation support. During these <br />visits we advised you on the suitability of the exposed soil for foundation support. We <br />reviewed the supplied Geotechnical Reports by David Nelson and Associates dated July <br />and October 1990 and the foundation drawings for the house plans as drawn by Thom <br />Nau. nan Design. <br />The final site inspection was completed on June 11, 1993. Footing forms and rebar had <br />been placed over most of the site at the time of our inspection. Observed bearing soil <br />consisted of interbedded tan to red brown, silty sand to sandy sill of the Whidbey <br />Formation as called out in the above referenced gemcchnical report by David Nelson and <br />Assoc. These soil are suitable for a maximum safe bearing load of 2000 psf. <br />The bearing soil is moisture sensitive. Seepage's were noted out of the base of the <br />excavation cuts along the western slope. In several locations, the bearing soil was over <br />excavated 12" to 16" below the footing elevation and replace with 2" to 4" crushed rock <br />to help drain the soil below the footings and to provide drainage pathways for the seepage. <br />We recommended that the foundation contractor remove any exposed moisture disturbed <br />soil from below the footings. These soil should be mucked out down to undisturbed soil <br />just prior to pouring the foundation. Under our direction, the eastern footing line was <br />over excavated to depths ranging 11— -m four (4) to six (6) feet below the established floor <br />grades. This area was over excavated to reach bearing soil and to allow the transfer of <br />bearing loads to the soil without loading the adjacent rockery. Drainage was provided out <br />(�"Urintrnf.
