Kettleman Lane <br /> Lodi, California <br /> pear Mr. Owen: <br /> _ In response to your request we have made a geotechnical review of the data <br /> for the above project to predict the stability of the soils during excavation. We <br /> understand that an excavation will be made to a maximum depth of 15' at ft. <br /> _ location on your'site map where borings 7, 8 and 11 through 16 are shown. The <br /> ! exi:::�avation will have near vertical sales. <br /> _. We have reviewed the logs and soil samples submitted to us by Aegis for <br /> borings 7, 8 and 11 through i S. They.show asphalt concrete and aggregate base at <br /> the surface underlain by.a stiff to hard dry clayey sandy silt. There was no free water <br /> ' encountered: <br /> Based on our review we pradic:that the soils will be stable during excavation <br /> with little shoring or bracing required. Any areas where there are sand lenses with <br /> J.� low'day and sift content may require some shoring or temporary bracing. We <br /> I recommend that the excavation be rformed under an engineers supervision: <br /> I <br /> J I trust this fulfills your request.
