Pits are required in this type of soil. r PERCOLATION TEST INFORMATION No pit was dug. The field form dated 3119109 contains the test data and is included in this report.The two 6" diamenter test holes were sleeved with 4" PVC pipe. Two inches of small gravel weere placed in the bottom of the holes. Additional gravel was placed aaround the PVC pipe as shown on the included schematic detail. The two holes were 42" deep. The 24 hour pre- soak began on 3118/09 at 1000 hours. (12" of water placed in each hole) Both holes were dry after the 24 hour pre-soak. The 4 hour test portion began at 1000 hours on 3119109. The tests conformed to SJC Policy EHD 02-02. Mr. Mike Escotto SR. R.E.H.S. was present for the required readings. Visual observations of the excavated soil indicated a satisfactory profile. Summary of tests: Both shallow holes failed.No tests were made on the Remainder. CONCLUSION In view of no plans to add new development,the expense of additional re-test at this time does not appear warranted. The parcel can be conditioned by the EHD to control development. The size of the parcel is 3.02 gross acres and 2.7 net. The domestic well requires a radius of 150' clear(1.6 acres), the irrigation well requires 0.8 acre clear and the two existing septic systems require an estimated 0.5 acres expansion, structures and paved area, also dirt road in back are in place.. There is not adequate room for another septic system with the present development considering clearance required from the property lines. 2.
