Structural fill that will be placed In wet weather should conaiat of a coarse, granular sail with a slit or clay content of no more than 5 percent. The percentage of particles passing the No. 200 sieve should be measured from that portion of soil passing the threeequarter-inch sieve. UMITATIONS The Conclusions and recommendations contained in this report are based on site conditions as they existed at the time of our exploration and assume that the soil and groundwater conditions encountered in the test borings are representative of subsurface conditions on the site. If the subsurface conditions encountered during construction are significantly different from those observed in our explorations, We should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. Unanticipated Conditions are Commonly encountered on Construction sites and cannot be fully anticipated by merely taking samples In test findings. Subsurface conditions can also vary between exploration locations. Such unexpected conditions frequently require making additional expenditures to attain a properly Constructed project. It is recommended that the owner consider providing a contingency fund to accommodate such potential extra costs and risks. This is a standard recommendation for all projects. This report has been prepared for the exclusive use of Opportunity Zone Development LLC and Its representatives, for specific application to this project and site. Our conclusions and recommendations are professional opinions derived In accordance with our understanding of current local standards of practice, and within the scope of our services. No warranty is expressed or implied. The scope of our services does not Include services related to construction safety precautions, and our recommendations are not Intended to direct the contractors methods, techniques, sequences, or procedures, except as specifically described in our report for consideration In design. Our services also do not include assessing or minimizing the potential for biological hazards, such as mold, bacteria, mildew and fungi in either the existing or proposed site development. In addition to reviewing the final plans, Geotech Consultants, Inc. should be retained to provide geote chnical conaultation, testing, and observation services during construction. This is to confirm GEOTECH CON9ULTFHB, INC.
