' tnedy/Jenks Consultants 1 5.1.1 CPT The CPT soil investigation was performed in March 2004 to assess in-situ soil and groundwater ' conditions. CPT testing and evaluation was conducted in four locations on the Jepsen Webb Ranch property (Figure 6), by Precision Sampling, Inc. The borings were advanced to depths up to 126 feet below ground surface (bgs)while subsurface information was collected for ' preparation of a hydrogeologic log. The total depths of the CPT borings are listed in Table 3, and the CPT logs and data are included in Appendix B. Three separate CPT runs (CPT-01, CPT-01A, and CPT-01B), spaced approximately 10 feet apart, were performed at Location 1 in an attempt to penetrate cemented sand at approximately 40 feet bgs. A HydropunchTm groundwater sample collection was attempted at approximately 38 feet bgs in boring CPT-01A in a clean sand to silty sand, however, the HydropunchTm remained dry after waiting for results for approximately one hour. ' The CPT boring at Location 2 encountered stiff clay from approximately 65 feet bgs to a total depth of 107.33 ft bgs. In CPT Location 3, the stiff clay was encountered at approximately 55 feet bgs to a total depth of 96.7 feet bgs and at location 4 the CPT encountered stiff clay at approximately 50 feet bgs to a total depth of 126 bgs (Table 3).The CPT logs suggested that groundwater was not present, and therefore HydropunchTm sampling was not attempted at ' these locations. In general, the soil types encountered at the four CPT locations were described as containing ' an abundance of silty clay soil mixtures (i.e., clayey silt to silty clay, clay to silty clay, and very stiff, fine-grained soil). Sandy soil mixtures (i.e., silty sand to sandy silt, very stiff sand to silty or clayey sand, and clean or gravelly sand)were encountered less frequently. ' Based on the CPT logs (Appendix B), the soil stratigraphy beneath the Jepsen Ranch can be divided into two general sections: the upper soil (0-60 feet bgs), which contains silty clay soil mixtures stratified with sand layers, and the sub-soil (60-126 feet bgs), which is described as lacking sand but contains predominantly clay soils. Based on information from the CPT logs, the upper soil profile (0-60 feet bgs) has been further subdivided into stratigraphic layers as summarized in Table 4. 5.1.2 In-Situ Soil Profile Sampling In June 2004, soil samples were collected from five different locations on the Jepsen Ranch property. Soil samples were analyzed to evaluate the conditions existing on the property and the characteristics of the soil for agricultural management purposes. Sample locations are shown in ' Figure 5 and analytical results for the samples are summarized in Table 5. A typical profile of the sampled soils shows the following general physical characteristics for ' surface and sub-surface soils: 0-36 inches (Surface) Dark brown, very hard, granular and sub-angular blocky structure, white nodules found in some profiles, roots throughout. 1 . 36-60 inches (Subsurface) Pale brown or yellowish brown, hard, sub-angular blocky or massive structure, white nodules found in some profiles, no roots. 1 t Reclamation Report, Page 14 Musco Family Olive Company g`s9vup'a0rvn;.^bf07A701Cd.�muscaofrveW&repat4eclamaten VMWI ralamaMo repertrext 812,04, o
