Veritas Construction Inc ES-4011.03 <br /> June 17, 2016 Page 8 <br /> Revised June 22, 2016 1 <br /> DISCUSSION AND RECOMMENDATIONS <br /> General <br /> Based on the results of our study, construction of the proposed light industrial development is <br /> feasible from a geotechnical standpoint. The primary geotechnical considerations associated <br /> with the proposed development include structural fill placement and compaction, pavement and <br /> foundation subgrade preparation, and underground utility and vault installations. <br /> In our opinion, the proposed structures can be supported on conventional foundations bearing 111 <br /> on competent native soil, recompacted native soil, or new structural fill. Suitable onsite soils <br /> can generally be considered for use as structural fill provided the soil moisture content is at or <br /> near its optimum level at the time of placement and compaction. Recommendations for site <br /> preparation, structural fill placement, retaining wall design, foundations, and other pertinent <br /> geotechnical recommendations are provided in the following sections of this study. <br /> This geotechnical engineering study has been prepared for the exclusive use of Veritas <br /> Construction Inc. and their representatives. The study has been prepared specifically for the <br /> subject project. No warranty, expressed or implied, is made. This study has been prepared in <br /> a manner consistent with the level of care and skill ordinarily exercised by other members of the <br /> profession currently practicing under similar conditions in this area. <br /> Site Preparation and Earthwork <br /> Initial site preparation activities will consist of installing temporary erosion control measures, I <br /> establishing grading limits, and performing clearing and site stripping (as necessary). <br /> Subsequent earthwork activities will involve mass site grading and related infrastructure <br /> improvements. <br /> Temporary Erosion Control , <br /> During construction, surface water runoff must be controlled around the site perimeter and <br /> topographically lower margins of the site. In general, erosion control measures for the site <br /> should incorporate silt fencing, drainage swales, temporary ponds, and plastic sheeting to cover <br /> stockpiles, as necessary. Additionally, exposed earth surfaces should be protected during <br /> construction to help reduce the potential for erosion and off-site sediment transport. <br /> Construction entrances should consist of quarry spalls underlain by a non-woven filter fabric. <br /> Quarry spall thickness will depend on subgrade stability at the entrance, but should typically be <br /> at least 6 inches. The temporary erosion control elements specified on the approved plans and <br /> applicable state and county stormwater permits should be implemented, as necessary, prior to <br /> grading activities. <br /> Earth Solutions NW, LLC i <br />
