DevCo, Inc. <br />April 1, 2019 <br />Site Preparation and Earthwork <br />ES-6516 <br />Page 5 <br />Initial site preparation activities will consist of installing temporary erosion control measures, <br />establishing grading limits, performing clearing and site stripping, and removing existing structural <br />improvements. Subsequent earthwork activities will involve mass site grading and related <br />infrastructure improvements. <br />Temporary Erosion Control <br />The following temporary erosion control measures should be considered: <br />Temporary construction entrances and drive lanes should consist of at least six inches of <br />quarry spalls to both minimize off -site soil tracking and provide a stable access entrance <br />surface. Placing geotextile fabric underneath the quarry spalls will provide greater stability, <br />if needed. Use of existing drive lanes for this purpose may be feasible and can be <br />considered during construction. <br />+ Silt fencing should be placed around downgradient areas of the site perimeter. <br />+ When not in use, soil stockpiles should be covered or otherwise protected. Soil stockpiles <br />should never be placed near the tops of slopes. <br />• Temporary measures for controlling surface water runoff, such as interceptor trenches, <br />sumps, or interceptor swales, should be installed prior to beginning earthwork activities. <br />+ Dry soils disturbed during construction should be wetted to minimize dust. <br />+ When appropriate, permanent planting or hydroseeding will help to stabilize site soils. <br />Additional BMPs, as specified by the project design team and indicated on the plans, should be <br />incorporated into construction activities. Temporary erosion control measures may be modified <br />during construction as site conditions require, as approved by the site erosion control lead. <br />Stripping <br />Topsoil was not observed within the extracted samples at the boring locations. Given the extent <br />of existing development and site improvements, we do not anticipate a uniform topsoil horizon <br />will be encountered during construction. If encountered, topsoil and organic -rich soil is not <br />suitable for foundation support or for use as structural fill. Topsoil and organic -rich soil may be <br />used in non-structural areas, if desired. <br />Earth Solutions INK LLC <br />
