Soil Suitability Study*MS-98-27*Parcel No . 1 & Designated Remainder <br /> building , a well and a septic system in the southeast corner of the <br /> parcel . The remaining property is unimproved and presently used to <br /> graze horses and a couple of goats . <br /> Soil Profile Test : On my "Field Percolation Data Sheets" , I have <br /> noted the soil encountered to be reddish-brown in color and either <br /> clayey or , sandy or granular , San Joaquin Loam. <br /> The University Of California publication entitled "Soils Of San <br /> Joaquin County , California" by Walter W . Weir , dated June 1952 , <br /> refers to the soil in this general area as possibly "San Joaquin <br /> Loam" , reddish-brown in color , with good surface and imperfect <br /> subsurface drainage or "San Joaquin Loam, Deep" , reddish brown in <br /> color with good surface and subsurface drainage . <br /> The Soil Survey of San Joaquin County , California , United States <br /> Department Of Agriculture Soil Conservation Service, issued October <br /> 1992 lists the soil type as San Joaquin Loam, 0% to 2% slopes , <br /> cemented layers in shallow excavations and reddish brown in color . <br /> The physical and chemical properties of the soil are listed as <br /> follows : <br /> Soil Name Depth Clay Permeability Shrink Swell P I ast i c i_t_y_ <br /> ( Inches) M ( Inches/Hr . ) Index <br /> San Joaquin 0- 16 15-25 0 . 6-2 . 0 Low NP- 10 <br /> Loam 16-26 35-50 Less than 0 . 6 High 25-35 <br /> 26-60 --- ---- ---- <br /> No water was encountered in excavating any of the percolation <br /> test holes to a maximum depth of 19 ' 10" . The San Joaquin County <br /> Flood Control And Water Conservation Map entitled "Lines of Equal <br /> Depth To Water Wells" dated Spring 1997 shows the water to be in <br /> excess of sixty feet ( 60) feet below the ground surface . <br /> Percolation Tests : Two ( 2) shallow Percolation Test Holes , Nos . PH1 <br /> and RPH , were excavated to depths of 34 . 5" and 35" respectively and <br /> tested in a non-standard manner ( 1 1 /2 hours long) and resulted in <br /> percolation rates of 480 minutes per inch for Parcel No . 1 and 240 <br /> minutes per inch for the Designated Remainder parcel as shown on <br /> the "Field Percolation Sheet" for test hole nos . PH1 and RPH which <br /> determined the need for deep percolation testing . <br /> Three ( 3) deep Percolation Test Holes were dug on November 5 , <br /> 1998 . One , designated URPH , was abandoned from further testing by <br /> visual inspection, and the other two were formally tested and are <br /> designated Nos . PH1A and RPHA . PH1A was dug to a depth of 19 ' 08" on <br /> Parcel No . 1 and the second , RPHA was dug to a depth of 9 ' 10" on <br /> the Designated Remainder parcel and were formally tested and are <br /> reported on in this report . <br /> The deep percolation tests were conducted and performed in <br /> accordance with the percolation test procedures outlined in the <br /> Noreen Thompson, 3157 East Woodson Road , Acampo Ca . 95220 3 <br />
