PERCOLATION TEST RESULTS: ON SEPTEMBER 12 , 1995 , THE PROJECT SITE WAS TESTED TO DETERMINE THE PERCOLATION RATE. PARCELS 1 AND 2 WERE TESTED. PARCEL 2 PASSED THE PERCOLATION TEST WITH A PERCOLATION RATE OF 60 MIN/INCH FOR A DEPTH OF 3 FEET. PARCEL 1 FAILED THE TEST AT A DEPTH OF 3 FEET . ON OCTOBER 3, 1995 , PARCEL 1 WAS RETESTED AT A DEPTH OF 3 FEET . PARCEL 1 PASSED THE PERCOLATION TEST WITH A PERCOLATION RATE OF 60 MIN/INCH . IT SHOULD BE NOTED THAT THREE HOLES WHERE TESTED FOR THE RETESTED OF PARCEL 1 WITH ONLY THE ONE HOLE PASSING THE TEST. PERCOLATION TESTS WERE CONDUCTED IN ACCORDANCE WITH SAN JOAQUIN COUNTY ENVIRONMENTAL HEALTH DEPARTMENT REQUIREMENTS. COMMENTS REGARDING EXISTING SEPTIC SYSTEMS: BASED ON THE INFORMATION GIVEN ON SHEET 5 , THE EXISTING SEPTIC SYSTEMS IN THE AREA ARE FUNCTIONING WITH NO PROBLEMS EXCEPT FOR THE REPAIR OF THE SYSTEMS LOCATED ON 1560 E. METTLER ROAD. GULZARA "CHARLES" JAGIR, THE NEIGHBOR TO THE EAST OF PARCEL 1 , INSTALLED A SEPTIC TANK AND SEEPAGE PITS FOR HIS HOUSE. MR. JAGIR SAID THAT HE HAS HAD NO PROBLEMS WITH HIS SEPTIC SYSTEM SINCE IT WAS INSTALLED. THE EXISTING SEPTIC SYSTEMS IN THE AREA ARE USING A SEPTIC TANK, SEEPAGE PIT OR PITS, AND LEACH LINES. SEEPAGE PITS WITH A DEPTH OF 25 FEET WITH A DIAMETER OF NO LESS THAN 33 INCHES ARE BEING USED FOR THE EXISTING SYSTEMS. ENGINEER'S OPINION SOIL SUITABILITY: FROM THE RESULTS OBTAINED FROM THE PERCOLATION TESTS AND EXISTING PERMITS FOR THE REPAIR AND INSTALLATION OF PRIVATE DISPOSAL SYSTEMS, THE SEPTIC SYSTEMS FOR THE PROJECT SITE SHOULD CONSIST OF A 12 ,000 SQUARE FOOT LEACH FIELD AREA WITH THE APPROPRIATE SIZE SEPTIC TANK AND SEEPAGE PITS FOR PARCELS 1 AND 2 . THIS CONCLUSION FOR THE USE OF SEEPAGE PITS IS BASED ON THE FAILURE OF SEVERAL HOLES THAT WERE DUG AT A DEPTH OF 3 FEET BEFORE AN AREA COULD BE FOUND WHERE IT WOULD PASS THE PERCOLATION TEST. EACH SYSTEM SHALL BE DESIGNED FOR THE SOIL CONDITIONS IN THE AREA, AND THE SIZE OF THE FACILITY TO BE SERVED. SEEPAGE PITS SHOULD HAVE A MINIMUM DIAMETER OF 33 INCHES, AND SHALL NOT BE INSTALLED TO A DEPTH OF GREATER THAN 25 FEET THE GROUNDWATER TABLE IS LOCATED APPROXIMATELY 55 FEET BELOW THE GROUND SURFACE. THEREFORE, THE GROUNDWATER LEVEL WILL MEET THE TEN FOOT MINIMUM DISTANCE BETWEEN THE BOTTOM OF THE SEEPAGE PITS AND THE TOP OF THE GROUNDWATER TABLE. THE SEPTIC SYSTEM SHOULD NOT ADVERSELY AFFECT THE GROUND WATER TABLE. IT IS OUR PROFESSIONAL OPINION THAT THE FINDINGS INCLUDED IN THIS STUDY ARE A REPRESENTATIVE ASSESSMENT OF THE PROJECT AREA AT THE PRESENT TIME. THIS OPINION CANNOT CONSTITUTE A GUARANTEE OR WARRANTY, EITHER EXPRESSED OR IMPLIED. SHEET 6
