report shows a 120' contour thru the approximate center of the farm. The land slopes to the west <br /> at an approximate slope of 0.005 ft/ft. The 110'contour is on the west side of Jack Tone Road. <br /> SOIL CONDITIONS Il <br /> In general the top 18" was dark organic clay. Clay was present to 25'with interspersed layers of <br /> gravel cemented with a silty sandy clay mixture. Moist clay was encountered at approximately 18'. <br /> Parcel 3 borings indicated a thin layer of sand at approximately 21'. Parcel 1 and 2 borings ofd <br /> March 7 did not indicate any percoble soil layer. The higher ground borings for the April 10 <br /> testing indicated during the drilling a less dense/cemented strata overall, with a gravel layer <br /> beginning at 8' and another gravel layer at approximately 20-25'. Pits would be required to reach <br /> the percoble layers. <br /> 911 <br /> SEPTIC TANK SITING q «- <br /> G� <br /> The septic tank will be located near the residence and should be a two compartment tank. If a <br /> pump is required,the distance to the leach field, the difference in elevation and the size of the line <br /> will determine the size of pump required. Parcel 3 and 4 are sites comparable with gravity flow <br /> type system. Parcel 1 and 2 maneed a um led to um the clear effluent to the leach <br /> field. A riser to grade would alsolie required to provide access to the pump/filter. We would <br /> recommend the biotube pump vault by OSI, or equal, should pumps be required. A fact sheet is <br /> enclosed. <br /> SEPTIC SYSTEM REPAIRS OF RECORD <br /> A search of the repairs of record typical for this area was conducted at the EHD, 3d Floor, <br /> Stockton, CA.
