Development <br /> 940 East Harney Lane <br /> Lodi, CA 95240 <br /> Subject: ADDENDUM TO SOILS SUITABILITY AND <br /> NITRATE LOADING STUDY <br /> ANDERSON STREET SUBDIVISION <br /> CLEMENTS, CALIFORNIA <br /> Reference: Kleinfelder, "Soils Suitability and Nitrate Loading Study, <br /> Anderson Street Subdivision, Clements, California," File <br /> No. 22276.G01, November S, 2002 <br /> Kleinfelder, "Addendum to Soils Suitability and Nitrate <br /> Loading Study, Anderson Street Subdivision, Clements, <br /> California,"File No. 22276.G01, June 9, 2003 <br /> Dear Mr. Wright: <br /> Kleinfelder is pleased to present this addendum to the referenced soil suitability and nitrate <br /> loading study for a proposed subdivision to be located east of the intersection of Anderson and <br /> Almond Streets in Clements, California. This addendum presents the results of a second set of <br /> percolation retests for parcel 2 of the subject subdivision. We understand that because of the <br /> location of a leach field on an adjacent property, the proposed leach field area for proposed <br /> parcel 2 was moved to accommodate the relocation of the residential well for this parcel. We <br /> understand that the first retests performed for our June 9 addendum were not located within the <br /> area of the proposed leach field. <br /> The subsurface conditions at the site were explored for this retest on June 12, 2003, by drilling <br /> two percolation borings to depths between approximately 3.5 and 19.8 feet below existing grade. <br /> The borings were drill'ed�tising a Simco 2400 truck-mounted drill rig equipped with 6-inch O.D. <br /> solid-stem auger. The location of these percolation retests was approximately 100 feet west and <br /> 90 feet south of the northeast parcel corner and is presented on the attached plate. <br /> Based on our findings, the subsurface soils encountered consisted of interbedded layers of <br /> weakly cemented to non-cemented brown sandy silts and silty sands to the depths explored. <br /> 22276.G02/ST03L327 June 16,2003 <br /> ©2003 Kleinfelder,Inc.
