The P200 and moisture content tests are shown on the Log of Boring Sheets <br />included in the Appendix, across from the associated soil sample. <br />C. Recommendations <br />C.1. Design and Construction Discussion <br />C.1.a. Building Subgrade Preparation <br />The preliminary plans indicate the proposed development will contain 2 apartment buildings and <br />1 senior living building that will all contain below grade parking levels, 3 slab -on -grade retail buildings and <br />11 slab -on -grade townhouse buildings. Based on the results of the borings and the anticipated finished <br />floor elevation of 930 feet for the buildings, we anticipate a soil correction will be required for the <br />buildings with fills up to about 10 feet required to establish grade. We anticipate the soil correction will <br />involve removing the topsoil, existing fill and soft/very loose soils. Also, any relic buried structures — such <br />as old pavements, wells, cisterns, utility lines, floor slabs or foundations, etc., should be removed from <br />building pads and paved areas. <br />Any areas of loose or disturbed sands in the excavation bottoms should be moisture conditioned, if <br />necessary, and surface compacted to increase the density and uniformity of the sands prior to footing or <br />fill placement. <br />C.1.b. Reuse of On -Site Soils <br />The on -site native soils, free of organic materials and debris, appear suitable for reuse as engineered fill. <br />Some of the on -site soils will likely require moisture conditioning (drying or wetting) prior to reuse and <br />compaction. However, the higher moisture content lean clay and the fat clay should not be used as <br />structural fill. Any materials to be used as engineered fill should be tested and approved by the <br />geotechnical engineer prior to placement. <br />C.1.c. Effects of Groundwater <br />Groundwater was encountered in 13 of the 14 soil borings during drilling. At the 4 borings performed in <br />the west portion of the site adjacent to the wetland, groundwater was encountered between depths of <br />about 8 to 9 feet, which correspond to elevations of about 895 to 896 feet. At 9 of the 10 borings <br />performed in the central and east portions of the site, groundwater was encountered between depths of <br />BRAUN <br />INTERTEC <br />
