This study was performed in accordance with <br /> KPFF Agreement No. 2000026 dated April 10, 2020. This report presents the findings of the <br /> subsurface exploration and provides geotechnical recommendations concerning earthwork, the <br /> ' design and construction of building foundations, floor slabs, excavation design, and pavements <br /> for the proposed project. We considered and incorporated mostly minor edits and revisions to the <br /> "draft" version of this report (dated July 31, 2020); this report supercedes the draft report. <br /> ' The site subsurface includes a thick layer of relatively dense granular fill atop a sequence of loose <br /> to dense layers of granular soil. Based upon the thick and relatively dense, granular upper soils <br /> ' and relatively low expected foundation and floor slab loads, we recommend support of the building <br /> on shallow spread footings. <br /> ' We appreciate the opportunity to be of service to you on this project. If you have any questions <br /> concerning this report or if we may be of further service, please contact us. <br /> Sincerely, <br /> Terracon Consultants, Inc. <br /> .00MAs <br /> Hof WA$,,,�4� , <br /> A,,Y16& <br /> 43 • <br /> 688 <br /> qlv,f <br /> ' <br /> Chad T.
