Soil Suitability Study"'*•" APN: 005-09-53 •"'•'Parcel Nos. 1 &2=2.0 and 2.1 acres respectively leach lines each 40' in length with three (3)pits at their ends, each thirty-three (33) inches in diameter and twenty-five (25) feet in depth. The property owner informed me that this existing facility was abandoned and replaced this summer to accommodate a lot line adjustment but the permit was not found in the records that I searched. The three (3)permits studied for adding to the existing systems involved installing leach lines varying from forty(40) feet to one hundred(100) feet in length with pits varying from thirty-three (33) inches to forty-eight(48) inches in diameter and all pits were twenty-five(25) feet deep. The six(6) permits reviewed for installing new facilities involved the installation of leech lines varying from forty (40) feet to one hundred one(101) feet long with pits at their ends varying from thirty-three(33) inches to forty-eight(48) inches in diameter. No permits were noted for repairing any of the facilities subsequent to their installation. From the historical septic records there is no indication of septic contamination problems. Two(2)of the ten(10)septic permits reviewed listed the soil type as clay, hardpan. Three (3) of the permits reviewed listed the soil type as hardpan. One(1) of the permits reviewed listed the soil type as clay. Another one of the permits reviewed listed the soil type as sandy loam and the remaining three(3)permits reviewed did not list a soil type. Possible Nitrate Pollution: No animals were seen on the subject property; so there does not appear to be any undue nitrate concentrations because of an overpopulation of animals. Groundwater Elevation: The San Joaquin County Flood Control and Water Conservation Map entitled"Lines of Equal Depth To Water Wells, dated spring 1998, shows the water table to be in excess of seventy(70) feet below the ground surface. Soil Character: The University of California publication entitled"Soils of San Joaquin County, California", by Walter W. Weir, dated June 1952, identifies the soil on the subject property to be San Joaquin loam, deep. SAKI JOAOUIN LOAM,DEEP San Joaquin loam deep soils are strongly developed hardpan soils and are derived from old alluvial deposits now occurring as terraces. They are composed largely of materials of granitic origin. The term "Red-Iron Hardpan Land" is commonly used to describe this soil. The soil is brownish-red,acid in reaction,and usually light to medium textured. Loam and sandy loam types are recognized in this soil classification. A typical profile of San Joaquin sandy loam follows: (1) To depth of about 9 inches,the soil is reddish brown, friable, easily penetrated by roots and water but bakes hard when dry. The pH is about 5.4. Rnhnrt W Tnwere 9SR19 Nn Ctatr Rtr 99 Fnat Frnntaon Rnnd Armm� Califnrnin 94990 9
