Indian River County File No . 06- 5699 -3 - 2 . 2 Test Locations The approximate locations of the borings are schematically illustrated on an aerial photograph obtained on - line and presented as Figure 3 . These locations were determined in the field by estimating distances from existing site features and other points of reference , and should be considered accurate only to the degree implied by the method of measurement used . If you need to know the boring locations more accurately , we recommend that you retain the services of a licensed surveyor. 2 . 3 Groundwater Measurements The groundwater levels were measured in the boreholes after stabilization of the downhole water level . The measured groundwater levels are shown adjacent to the soil profiles on Figure 5 . As shown on Figure 5 , groundwater was encountered at approximate depths ranging from 2 . 5 to 5 . 2 feet below the ground surface on the dates indicated . Fluctuations in groundwater levels should be anticipated throughout the year primarily due to seasonal variations in rainfall and other factors that may vary from the time the borings were conducted . We note that water will likely " perch " temporarily atop the shallow clayey and hardpan soils at the site during periods of heavy or prolonged rainfall . 3 . 0 LABORATORY TESTING PROGRAM 3 . 1 Visual Examination and Classification Testing Representative soil samples obtained during our field sampling operation were packaged and transferred to our laboratory for further visual examination and classification to obtain more accurate descriptions of the existing soil strata . The soil samples were visually classified in general accordance with the American Association of State Highway and Transportation Officials (AASHTO ) Soil Classification System (ASTM D - 3282 ) . In addition , grain size analysis (ASTM Method D422 ) , Atterberg limits testing (ASTM Method D- 423/424) , moisture content (ASTM D-2216 ) and organic content tests (ASTM Method D -2974 ) were conducted on representative soil samples to aid in classification of the soils . The results of our tests are shown adjacent to the sample depth on the soil boring profiles presented on Figures 5 . The resulting soil descriptions and the results of our tests are also summarized shown on Table 3 . Particle size analysis results are included in Appendix II .
