Grading. <br /> ff VJ <br /> � The wetland/mitigation area will be excavated at the <br /> H initiation of �the project. The area will he graded to the <br /> H o� � proposed contours for introduction of the organic soil base <br /> from the existing northwest wetland and nati.ve vegetation. A <br /> temporar5• sedimentation basin will be constructed with <br /> sediment detention collection points/sedimentation ditches in <br /> .. <br /> the southwest corner and central portion of the wetland <br /> mitigation/retention pond area (SD-].) . The collection points <br /> and sedimentation ditch will be sodded on the outside to <br /> reduce the possibilities of erosion or r,tructure failure. <br /> Additional hay bales will be placed between the central <br /> ,, collection points/sedimentation ditch and the protected <br /> wetland . These are temporary measures to reduce the <br /> '�' possibilities of sediment or equipment impacts to the retained <br /> natural wetland areas during construction . After <br /> ��' construction, the temporary ctructure will be removed and the <br /> '�' .. area planted. nny exceasive sediment deposits will also be <br /> removed at this tin�e. These fences will be removed at the <br /> ��� same time as the temporary sediment collection <br /> f�' points/sedimentation ditches. . <br /> � ' .,, Prior to excavation, selected trees which will be <br /> identified and flagged by the wetlands const:ruction supervisor <br /> � ' and the wetlands biologist to identify those trees that will <br /> ' be removed and replanted into the mitigatio.n area. Once this <br /> is completed, the remainder of the area, with the exception of <br /> '�' .+ the exieting wetlands, will be graded to the proposed <br /> ' elevations (Construction Drawings) ) . The site will be graded <br /> � to create the 561-564 foct elevation areas in the bottom of <br /> '� the retention pond area. The areas surrounding and adjacent to <br /> �' the existing wet].ands will be graded up to the edqe of the <br /> � �� flagged wetland. This may require some harn9-clearinq in an <br /> effort to maximize the wetland design features of the <br /> mitigation plan without disturbing the existing remaining <br /> wetlands. The slopes from 564 to the top of the slopec and to <br /> create the permanent peninsula will be created. These provide <br /> "' the shrub/tree replacement areas and the 25 foot bufler area <br /> surrounding the wetland portion of the site (SD-7) . <br /> 3 <br /> ... <br />
