1 <br /> The test hole was constructed b first placing about 1 to 2 inches of ea gravel in the bottom of <br /> Y P g p <br /> the hole. A 1.5" diameter perforated pipe was then placed in the hole. Pea gravel;was then <br /> added to the annular space around the pipe to about 1 foot high. The hole was pre,-saturated 24 <br /> hours prior to testing. <br /> t5.3 Description of soil lithology as noted from test pit by appropriate professional using <br /> ' industry standard protocol: The soil in this area was found to be fat clay with some organics <br /> as described in Anderson's report in the Appendix. L <br /> F. <br /> 5.4 Discussion of soil lithology as related to future onsite septic c uses: The fat clay has very <br /> low permeability. Also, with high ground water, an engineered septicY q s stem is required.

If the property is ever de:veloped (�.y� <br /> further, additional holes will be required. <br /> 6.3 Description of the Date, Time and Protocol Used to Prepare the Test Hole, Including <br /> F, Depth and Dimensions of Hole, Preparation of Hole, and Depth of Water Used to Presoak <br /> (Minimum 12 Inches): The shallow test holes were excavated to a depth of 18 inches and <br /> 8 inches in diameter and backfilled with 1 to 2 inches of"pea gravel" in accordance with County <br /> [. Standards. The shallow holes were prepared by staff of Neil O. Anderson & Associates on <br /> March 28, 2005. On March 28 2005 at 7:30 a.m. the 24 h 'I <br /> our presoak period was started. The <br /> hole was filled with 12 inches of water over the gravel and at this time Environmental Health <br /> _ Department was notified of the start of the test. <br /> 6.4 Description of the Date, Time and Condition of the Test Hole After the 24='Hour Soak <br /> Period (Hole Still Intact,Hole Dry,Depth to Water Remaining in Hole,Etc.)•!, On March 29, � <br /> 2005 the test holes were dry and deemed suitable for testin . <br /> F g <br /> = 6.5 The Test Conformed to San Joaquin County Policy EHD 02-02 (Correct Depth, <br /> diameter, 2" gravel, 6" Water Refill, Correct Readings Recorded): The percolation tests <br /> could not conform to San Joaquin County Policy EHD 02-02 due to high groundwater.
