A layer of clean, 2-to-4-inch quarry spans should be placed over areas of frequent traffic, such as the entrance to and exit from the site to protect the subgrade soils from disturbance by construction traffic. A silt fence should be installed along the downhill sides of construction areas to minimize transport of sediment by storm runoff onto neighboring properties or the gully bottom, The bottom of the filter cloth of the silt fences should be anchored in a trench filled with onsite soil. Intercepting ditches or trench drains should be installed around the construction areas, as required, to intercept and drain away storm runoff and near-surface perched groundwater seepage. Water captured by such ditches or trench drains may be discharged onto a reek spat'pad constructed at gully bottom to prevent erosion, Spoil soils should be hauled off of the site as soon as possible. SITE PREPARATION AND GENERAL GRADING Vegetation within construction limits should be cleared and grubbed. Loose topsoil and weak weathered soil should be completely stripped down to very-dense glacial till soil within building pad of the proposed residence, while topsoil and unsuitable soil in the root zone should be stripped down to clean medium-dense weathered soil or very-dense glacial till soil within the footprint of the driveway, The exposed soils should be IAU & ASSOCIATES, INC.
