JOSEPH A. CESARE AND ASSOCIATES, INC., GEOTECHNICAL ENGINEERING CONSULTANTS J & S Farms, Connecticut, and Jim Rodgers #1 and #2 Pits. The Lamar Park Pit is currently in operation. The eastern boundary of this pit borders the West Farm Property. The only pit within the property limits is the inactive Connecticut. INVESTIGATIONS Subsurface conditions were investigated by drilling twelve test holes at the locations shown in Figure 2. Test Holes KN301 through KN312 were advanced using a 6-inch outside diameter, solid-stem, continuous-flight power auger powered by a CME-75 drilling rig operated by Spectrum Exploration. These holes were drilled on April 9 and 10, 2007. Test Holes were vertical and advanced to bedrock. Bulk samples of the sand and gravel encountered were collected during auger drilling. In general, the bulk samples were collected directly off the augers as they were removed from the hole. The volume of the bulk samples was approximately three gallons. The bulk samples are considered to provide a reasonable representation of the in-place sand and gravel units. The material sampled, however, may not be representative of the overall sand and gravel units. Based on our experience, auger drilling has a tendency to push gravel and cobble sized material to the side of the drill hole, creating a finer-grained material at the surface. In addition, _ material collected beneath the water table will tend to have a lower percentage of clay/silt sized material than actual since the fine fraction will have a tendency to drain away with the water as the material is brought to the surface. The drilling was performed under the supervision of a JAC/CTS representative who maintained logs of the borings, visually classified the soil and bedrock encountered, and obtained samples for laboratory testing. Based on our scope of work, the test holes were completed to depths ranging from 20 to 73 feet. Results of the logging are presented on the Logs of Test Holes, Figures 3 through 5. The elevation and coordinates of the holes are shown in Table 1. All coordinates were obtained with a hand-held GPS unit and should only be considered accurate to within 15 feet. LABORATORY TESTING Samples were delivered to the laboratory where there were visually classified and appropriate testing assigned to specific samples to evaluate pertinent engineering properties.
