,Soil Suitability Study';Diamond Crest Estates Subdivision,Parcel I =43.I0 Net Acres,With Access Off <br /> Of A Dirt Road Off Of Kasson Road,APN: 255-34-07 <br /> The rate of water intake for the soil is 0.1 inches per hour. The general use for this <br /> soil is for irrigated crops and a few homes. <br /> i Some problems that are associated with development of the property are(1) slow <br /> permeability, (2)high shrink-swell potential, (3)high water table and (4) low strength. <br /> h <br /> r No water was encountered in excavating the Percolation or Soil Profile test holes <br /> on the subject parcel to a maximum depth of 10'00". Refer to the attached"Field, <br /> Percolation Data Sheet", and"Parcel Map"as well as the text of this report for the <br /> specific soil layer characters encountered as well as and test hole location details. <br /> SEPTIC SYSTEM ANALYSIS: San Joaquin County Public Health Services, <br /> Environmental Health Division septic permit applications were reviewed. Six(6)permit <br /> `applications were reviewed in the general area of the subject property. Five were on <br /> Kasson Road, one was on Airport Way and none were reviewed on Durham Ferry Road, <br /> nor was any found for the subject property of this report. . <br /> All six(6) of the permits were for leach field installations with leach lines varying <br /> in number from one(1)to four(4) and from sixty(60) feet to one hundred(100) feet in <br /> length. One(1) of the six(6)permits reviewed contained an initial inspection note that <br /> ` there might be a possible future failure of the system..Another permit of the <br /> six(6)indicated that the system was indeed replaced six(6)years and five (5)months <br /> later. The permits reviewed were dated from November 17, 1972 to January 29, 1991. <br /> PERCOLATION TEST: Only one (1)parcel is covered in this report and was the only90�r5t, <br /> reported hp on. The parcel covered and reported on is <br /> Parcel 1 and is shown on the attached"Parcel Ma rA � <br /> one requested and contracted to be ep p 1� bN�[ <br /> " and the "Diamond Crest Estates <br /> Subdivision Map". <br /> On Tuesday,March 19, 2002, a Percolation Test Hole identified as PH IC was <br /> excavated to a depth of 35 112" and a Soil Profile Test Hole was excavated on <br /> Wednesday to a maximum depth of ten 10'00" as noted on the attached"Field <br /> Percolation Data Sheet". The location of these test holes are depicted on the attached <br /> "Parcel Map". The Percolation Test Hole was presoaked on Tuesday,March 19, 2002 <br /> and the percolation readings were made and the percolation rate determined on <br /> Wednesday,March 20, 2002. <br /> Also two other preliminary excavations were made at site locations PH 1A and <br /> PH 1B shown on the attached"Parcel Map". However, these sites were not fully <br /> excavated to conform to County established test requirements due to the density and <br /> hardness of the soil being excavated and the high amount of clay present in the soil <br /> indicated by theability to mold the soil in one's hand. It was not until the third site <br /> selection that soil suitable to fully test was encountered. <br /> f <br /> Lisa Ward, 1034 Central Ave.,Tracy,California 95376—3915,(800)836-1404, (209)836-1404 <br /> d <br /> f <br />
