<br /> <br />Mitigation sites will be located in selected areas along site perimeter and one azea along access <br />road (Appendix B, W-1 and W-2). Site selection is based on areas abutting undisturbed lands <br />where benches can be hydraulically connected with river groundwater system. Mitigation sites <br />and project area aze within the same watershed sub-basin. <br />4.1 Mitigation blethods <br />Excavated wetland material will be evenly distributed over prepared bench areas. When bench <br />areas are greater than excavated areas, transplanted materials will be evenly placed, leaving the <br />completed bench interspersed with wetland materials and unplanted areas. The intention of this <br />practice is to facilitate the establishment ofwetland vegetation over the entire bench area. <br />4.2 Location and size of Mitigation Area <br />Project mitigation efforts will be initiated during construction of access road. A 400 s.f. area of <br />wetland materials in the Monument Creek wetland crossing will need to be transplanted prior <br />receiving fill (Appendix B, W-2). These materials will be directly transferred to a previously <br />prepared area (800 s.f.) adjacent to existing wetland {refer to Appendix B, DS-2). The prepared <br />area will tie in with existing wetland water regime to support vegetative growth. <br />Phase A wetland mitigation, in the Phase I Mining area (Appendix B, MP-1), involves stripping <br />and stockpiling topsoil and subsoil separately for preparing a 200-foot wide and 350-foot long <br />wetland bench. Excavation and replacement ofwetland materials will occur simultaneously to <br />minimize transplant shock and increase success in reestablishing wetland vegetation. <br />The I.OS acres of wetlands occurring in the Phase I area and Processing Site will be transferred <br />directly into the prepared wetland bench creating 1.6 acres of constructed wetlands under the <br />Phase A operative (Appendix B, W-1). Mitigation for wetlands excavated for access road <br />construction in Processing Site area will also be included in Phase A. Project mitigation using this <br />type of strategy is advantageous in that it avoids temporal wetland losses and increases net site <br />acreage ofwetland habitat. <br />Phase B mitigates 2.8 acres of wetlands occurring in the proposed Phase C wetland mitigation in <br />Mining Phase III area (Appendix B, W-1). These wetlands will be used to create a 5.5-acre <br />constructed wetland bench (800' X 350') along the northwest side of Phase II Mining area. Bench <br />substrate will be constructed with backfilled subsoil and topsoil covered with excavated wetland <br />4-I <br />
