A copy of our field percolation test results for P-1 and P-2, <br /> along with a plan showing the approximate test dole locations, are attached. <br /> I <br /> E <br /> P-1 3.2 125 <br /> P-2 9.5 15.6 <br /> P-3 25 25 <br /> The above test results and our observations indicate that the percolation characteristics of the <br /> upper clays and silts will not meet the rainimum SJCPHS percolation criteria, (minimum 60 <br /> minutes/inch or faster) for on-site sewage disposal. The percolation characteristics. of the <br /> underlying silty sand encountered at a depth of about 9 feet below site grade satisfies SJCPHS <br /> criteria. Accordingly, sewage leach trenches should either extend as required into the silty scud <br /> stratum or shallow trenches connected to seepage pits that extend into the silty sand will be <br /> required. <br /> This completes the scope of work requested. Our work was performed in general accordance <br /> with the standard of cage that exists in San Joaquin County. No other guarantee or warranty, <br /> expressed or implied is made.
