SOIL SUITABILITY STUDY OCT 1991 <br /> FOR THE ENVIRONMENTAL HEALTH <br /> ERVIN KOST PROPERTY <br /> PARCEL MAP NO. MS-91-109 PERM,!T/SERVICE; <br /> 26422 NORTH KENNEFICK ROAD, GALT, CALIFORNIA 95632 <br /> Prepared By <br /> Walter E. Curtis <br /> Civil Engineer <br /> C.E. # 11584 <br /> 418 Matthew Plaza <br /> Lodi , California 95240 <br /> Phone: ( 209) 368-4159 <br /> PROJECT DESCRIPTION: To divide a 20 acres parcel into two parcels , <br /> Parcel Nos . 1 and 2 . Parcel No. 1 is to <br /> contain 15 acres and Parcel No. 2 is to <br /> contain 5 acres . The 20 acres parcel has a <br /> home on it and the major portion of the parcel <br /> has been devoted to agricultural pursuits in <br /> TEST RESULTS : the past but is not being farmed presently. <br /> Parcel No . Test Hole Percolation Rate Minimum Usable <br /> N0 . (Minutes Per Inch) Disposal Area <br /> (Square Feet ) <br /> With Pits <br /> 1 SIC (3 ' ) 120 Failed <br /> 1 DID ( 13 ' 11 " ) 24 12 , 000 + Pits <br /> 2 S2 (3 ' ) 120 Failed <br /> 2 D2 ( 19 ' 08" ) 20 12 , 000 + Pits <br /> Soil Profile: The deep percolation test hole excavations dug to a <br /> maximum depth of 25 feet are used for Soil Profile reporting. See <br /> the attached "Field Note Sheets"and "Parcel Map" as well as the <br /> text of this report for specific soil layer , character and location <br /> details . <br /> Well Water Analysis : None was required. <br /> RECOMMENDATIONS : Soil porosity does not permit the use of a <br /> subsurface horizontal leach field solely and <br /> effluent is recommended to be discharged , in <br /> combination with subsurface horizontal leach <br /> E. C� '�l� lines into seepage pits at a maximum depth of <br /> twenty-five feet . Since the 3-foot depth <br /> 1184 T percolation tests failed to meet and the deep <br /> * a percolation tests did conform to San Joaquin <br /> Iz-3t-9 County Health Service, Environmental Health <br /> * Division minimum requirements , The sewage disposal <br /> -�OFCkj.� system recommended is a minimum usable 12 , 000 <br /> square feet disposal area plus pits in addition. <br />
