In addition depth to first ground water is four <br /> to four and a half feet. The bottom of leach line trenches must be at least five <br /> feet above ground water. <br /> You have the following alternatives : <br /> 1. Run additional percolation tests on the same parcels in a more <br /> suitable area that would meet county requirements . The area <br /> chosen would also have to meet the five foot leach line trench <br /> to ground water requirements . <br /> 2. Provide an engineer designed alternative sewage disposal system <br /> meeting Health District requirements . <br /> 3. Re-locate the parcels to another area and run percolations and <br /> soil profile tests that meet minimum requirements. <br /> Approval of the final map will be withheld until suitable test results can be obtained <br /> or an alternative design is submitted and approved by this District. <br /> If you have any questions regarding this matter, contact Fred Kaufman, Supervising <br /> Sanitarian, of my staff at (209) 466-6781 , extension 35. <br /> Jogi Khanna, M.D. , M.P.H. <br /> District Health Officer <br /> l Ron L.
