Box 15002 <br /> Sacramento, CA 958.!I51 <br /> Subject: ADDENDUM TO SEPTIC SYSTEM SUITABILITY STUDY <br /> REPORT DATED JANUARY 27, 1992 S^/�1 NNED <br /> SUBDIVISION ON NORTH CLEMENTS ROAD <br /> SAN JOAQUIN COUNTY, CALIFORNIA <br /> 4 Dear Mr. Sandman: <br /> k <br /> I This letter addresses several questions from Mr. James Miller with <br /> San Joaquin County Environmental Health regarding the referenced <br /> septic system suitability study report. Reference is also made to <br /> our report dated May 26, 1992, which was prepared for the subject <br /> project. <br /> Our responses to Mr-� Miller' s questions are as follows: <br /> • We understand that the site is surrounded by pasture <br /> on all four [`sides, which has been the case for as <br /> long as Bert` �can remember. The site has been used <br /> strictly as pasture for the last three years. Prior <br /> to the last three years, portions of the site <br /> contained vineyards and olive orchards. <br /> �s <br /> The percolation tests were performed on January 21 <br /> and 22 , 1992 . The test holes were presoaked per <br /> County guidelines the days before testing (January <br /> 20 and 21, .1992, respectively) and were left to soak <br /> overnight, <br /> • As noted in Table I on page 3 of our January 27, <br /> 1992 report,. only one 3-foot deep test passed, and <br /> it just met the minimum percolation rate acceptable <br /> ! by the County for standard leach lines. The deeper <br /> tests produced significantly faster results. <br /> Therefore, although one 3-foot deep test did pass, <br />+ it is our opinion that septic systems at- the site <br /> will likely !' have to be designed using sump pits, <br /> G extending toIminimum depths of approximately 8 to 10 <br /> feet. Once is the remainder of the lots are tested, <br /> the required depths. of the sump pits can be <br /> determined. <br /> �i <br /> e.y .��r 149q 'ICLei ffe�ld r, Inc: <br /> KLEIN��[JEK -9 's Eas{�]vlyrtie Street, Stockton, CA 95205 (209) 948-1345 <br />
