<br /> PERCOLATION TESTS:
<br /> Percolation test holes were determined to be required on both Parcels A and B to
<br /> create two (2) parcels out of the larger single parcel as a result of inquiries made to the
<br /> San Joaquin County Public Health Service,Environmental Health Division,
<br /> On Friday, August 24, 2001, with hand auguring equipment, I dug two (2)
<br /> shallow 8" diameter percolation test holes,PB1 and PB2, 35" and 421/2" inches deep
<br /> respectively, on Parcel B. On Saturday, August 25, 2001, with power equipment,the
<br /> property owner excavated three shallow 12" diameter percolation test holes,PA,PB3 and
<br /> PB4. Percolation Test Hole PA is situate on Parcel A and Percolation Test Holes PB3 and
<br /> PB4 are situate in Parcel B. By visual observation percolation test holes PB 1, P2 and PB3
<br /> were abandoned from further testing beyond their excavation. Percolation Test Holes,PA
<br /> and PB4 were fully tested based on both visual observation and preliminary two-hour
<br /> percolation testing. All of these Percolation Test Holes are shown on the "Test Hole
<br /> Locations Map".
<br /> On Monday, August 27, 2001, the shallow percolation test holes on Parcels A and
<br /> B,Percolation Test Holes PA and PB4,repecfully, were presoaked overnight and
<br /> percolation readings were conducted on Tuesday,August 28, 2001.
<br /> Percolation Test Holes PA and PB4 shown on the attached"Test Hole Locations
<br /> Map"were tested over four-hour periods and the results of the four-hour percolation tests
<br /> are tabulated below. Percolation Test Hole PA on Parcel A met the standards for leach
<br /> field construction but Percolation Test Hole PB4 did not and thus necessitated further
<br /> deep hole (25' max. depth)percolation testing.
<br /> On Tuesday, September 4, 2001,Hillside Geotechnical Drilling drilled Deep
<br /> Percolation Test Holes PB5,PB6, PB7 and PB8 at the locations shown on the attached
<br /> "Test Hole Location Map". Deep Percolation Test Hole PB7 is used as the Soil Profile
<br /> Test Hole(SPH). Deep Percolation Test Holes PB5, PB6,PB7 and PBS were drilled to
<br /> depths of 11.27', 15.3', 23.0' and 13.2', respectively. Because of visual observation and a
<br /> preliminary one(1)hour test fast percolation rate determination , only Deep Percolation
<br /> Test Hole PB5 was formally tested further beyond initial drilling. The rest of the Deep
<br /> Percolation Test Holes were not tested further beyond their initial drilling, except for the
<br /> use of Percolation Test Hole PB7 being used as the Soil Profile Test Hole (SPH).
<br /> On Tuesday, September 4, 2001,Deep Percolation Test Hole was presoaked over night
<br /> and percolation readings were conducted on Wednesday, September 5, 2001.
