element to help evaluate soil capacity for water quality treatment. The CEC tests and organic <br /> content tests were performed by AMTest Laboratories. A summary of the test results is provided <br /> in Table 2. <br /> Table2.:...CEC and,Organic Content Analytical Results Summary' <br /> Sample Organic <br /> CEC <br /> Exploration Depth Soil Type Content <br /> (meq per 100 grams) • <br /> (feet BGS) (percent) <br /> Silty Sand with 8.9 2.8 <br /> TP-S 2.0 gravel Fill <br /> 1. Suitability for Water Quality Treatment: CEC greater than 5 meq per 100 grams and organic content a minimum of <br /> 1.0 percent(DOE,2012) <br /> The full analytical laboratory test report of the CEC and organic content test results is presented <br /> in Appendix B. <br /> 7.0 DESIGN <br /> Based on our review of the proposed preliminary development plans and the results of our <br /> explorations and analyses, it is our opinion that the proposed development can be constructed at <br /> the site. Our recommendations are provided in the following sections. <br /> 7.1 SEISMIC DESIGN CRITERIA <br /> 7.1.1 IBC Parameters <br /> Based on our explorations and analysis, the following design parameters can be applied if the <br /> structures are designed using the applicable provisions of the 2015 IBC. The parameters in <br /> Table 2 should be used to compute seismic base shear forces (IBC, 2015). <br /> Table 2.
