[2] Cont. <br /> 1985, an application for permit was submitted for repair/addition <br /> work on the subject Parcel #1, consisting of a pre-cast concrete <br /> septic tank and leach line installation. This work was performed <br /> on a residential structure on Parcel #1 of the subject property for <br /> the applicants of this minor subdivision. <br /> [3] PROPOSED DEVELOPMENT OF THE SUBJECT SITE <br /> It is proposed to divide 41. 33 acres into two portions (see <br /> Tentative Map in Appendix) . Parcel #1 will be composed of 2 . 0 <br /> acres and the remainder will contain 39. 33 acres. At the time of <br /> this study, information was not available to Quality Control <br /> Inspection, Inc. as to proposed development of the remainder <br /> property. <br /> [4] SOIL PROFILE AND PERCOLATION TESTING <br /> The soil profile from the on-site exploratory boring indicates that <br /> the soil is very heavy with clay from the surface down to 20 ft. <br /> Due to the clay soil structure encountered, three percolation test <br /> borings were drilled to observe three different soil strata. These <br /> depths were 42 inches, 7 . 5 feet and 12 feet. <br /> The percolation tests conducted by Quality Control Inspection, Inc. <br /> were performed in accordance with San Joaquin County Environmental <br /> Health Department regulations. The test results are located in the <br /> Appendix of this report. These percolation test results illustrate <br /> a rate of 9 min/in for the 42 inch boring, 60 min/in for the 7. 5 <br /> ft boring and 120 min/in for the 12 ft boring. It is the opinion <br /> of Quality Control Inspection, Inc. that the rate for the shallow <br /> hole at 9 min/in is suspect due to the clay nature of the soil at <br /> this depth. Although this percolation rate is theoretically <br /> possible in this type of soil under extremely ideal conditions, it <br /> 2 <br /> ®. Q-1ity Control Inspertion <br />
