OLD RIVER GOLF COURSE <br /> Page No. 2 <br /> River levee. At the time of our field investigation, the proposed <br /> building pad had recently been planted in a row crop. <br /> The leach field for the septic system will be located <br /> northwest of the club house, between the club house and the power <br /> transmission line easement. <br /> III FIELD EXPLORATION AND LABORATORY TESTING <br /> The field investigation conducted at this site consisted of <br /> drilling 3 exploratory test borings carried to depths of 9. 5 to <br /> 10.0 feet. Test borings B-1 and B-2 were performed at the club <br /> house location and test boring B-3 was performed in the area of the <br /> proposed leach field. The test borings were drilled with a truck <br /> mounted Deep Rock drill rig, utilizing 4 inch continuous flight <br /> auger. The location of the test borings is shown on the location <br /> map, Plate No. 1. The corners of the proposed building pad were <br /> staked and the test borings were located by these corners. <br /> Sampling of test borings B-1 and B-2 was performed at various <br /> depths by a California Modified 2 .5 inch o.d. split spoon sampler <br /> with brass tube liners. The sampler was driven by a 140 pound <br /> hammer with a 30 inch drop. Blow counts required to drive the <br /> sampler every 6 inches were recorded and this information is <br /> presented on the Log of Boring sheet, Plate No. 2 . Test boring B-3 <br /> was performed to log the soil strata in the area of the proposed <br /> leach field and no sampling of this boring was performed. <br /> Relatively undisturbed soil samples obtained from the test <br /> borings were preserved in brass tubes until the samples could be <br /> tested in the laboratory. Samples were taken to the laboratory of <br /> Neil O. Anderson & Associates, Inc. , Stockton, California and used <br /> for performing various laboratory tests. Tests performed consisted <br /> of unit weights and moisture contents. A summary of the test <br /> results is presented on the Log of Boring sheet. Pocket <br /> pentrometer readings were also made on select samples and these <br /> readings are presented on the Log of Boring sheet. <br /> A total of 5 sack samples were obtained of surface soil along <br /> proposed roadway alignments for the purpose of performing R-value <br /> _ tests. Samples were obtained from the 0 to 12 inch depth. For <br /> approximate locations of samples see the Location Map. The results <br /> of the R-value tests are presented on Plates No. 5 through 9. <br /> Z W <br /> � O � <br /> SSS O G\ <br /> r <br />
