' ( i minimum 20-foot effective setback by measuring the horizontal distance from the botrom of U�e foundation to tl�e edge of Uie slope. To mitigate and reduce the erosion hazard and potential for off-site sediment transport, wc recommend die follo�ving: I. Surface water should not be allowed to Flow across thc site over unprotected surfaces. 2. Silt fences should be placed and maintained around the downslope perimeter of the proposed construction arca througho�t the entire construction phase of the project imtil permanent landscaping has been installed. 3. Soils tliat are to be reused around die sitc should be storeJ in such a manner as to reduce erosion from thc stockpile. Protectivc measums may include, but are not necessarily limited to, covering ��ita plastic sheeting, the use of low stockpiles in flat areas, or the use of hay bales and/or additional silt fences aruund pilc perimeters. Soils should not be stockpiled on the steepty sloping portions of the site. 4. Areas stripped ef namral vegetation during cunstruction shoulJ be replanted as soon as possible or othcnvise protectcd. Wc havc cnjoyed working with you on this study and arc confident that the recommendations presented in this Ietter will aid in the successful completion of' your project.
