Highway 99 Frontage <br /> Manteca, CA 95336 <br /> Attention: Dave Rose <br /> Subject: TEST BORING AND PERCOLATION TEST <br /> PROPERTY AT 13404 SOUTH HIGHWAY 99 FRONTAGE <br /> SAN JOAQUIN COUNTY, CALIFORNIA <br /> Gentlemen: <br /> As requested, on October 10, 1989 representatives of our firm drilled one test boring <br /> to a depth of approximately 10 feet and drilled and set-up one 3-foot deep percolation <br /> test hole at requested locations. The test boring and percolation test hole were <br /> drilled with a truck mounted drill rig using continuous-flight auger. A continuous log <br /> of the soils encountered in the test boring was maintained by our representative and is <br /> presented on the Log of Boring, Plate Il. All soils have been classified according to <br /> the Unified Soil Classification System which is presented on Plate I. <br /> The percolation test hole was filled with water on October 19, 1989 and left to soak <br /> overnight. A representative of our firm returned to the site on October 20, 1989 and <br /> performed the percolation test per San Joaquin County guidelines. The test was <br /> performed for a period of four hours and the last 30 minutes was used to calculate <br /> the percolation rate of 34 minutes per inch. The county approved percolation field <br /> test sheet is included with this letter. <br /> We trust this letter presents the information requested at this time. If you have any <br /> questions, please contact us. <br /> Respectfully submitted, <br /> KLEINFELDER, INC. <br /> N 7 V 1989 <br /> L <br /> Steven R.
