The proposed Dew wetland areas will be created by excavating down from the exiftiDS eont ours •dijaccot to the wettaod as shown on F^ure 3. The new wetland areas are projected to become senqwnnaDentty-flooded and seasonally-flooded wetland (FUBF/PEMIQ fiinges of the existing wetland with the berm expected to become saturated forested (PFOIB) wetland. A combination of native, non-invasive seed mix and seedlings^higs similar to the mix in Attachment A will be establisbed along the edges of the new wetland areas. Native, non-invasive tree species such as American tamarack, northern white cedar, black ash, green ash, or silver maple will be planted on the proposed berm, depending upon availability. The proposed upland bufier areas win be a nimintum of 16.S feet wide abng the southern and eastern sides of the wetland, and a minimum of 25 feet wide along the northern edge of the wetland. A native, non-invasive plant comnainity will be established in the proposed upland buffer areas a mix similar to that irvb«^ in Attachment A. The t^land buffer area along tbenorthcmedgeofthewetland will be maintained in the existing woody vegetation, with the exception of invasive species such as common buckthorn, which will be removed. In summary, the proposed project will partially restore an excavated wetland basin by constructing an eait^ bens, which will be used to estahlLsh emergent herbaceous and woody vegeution. In addition, 2,135 sf of new wetland and 11,787 sf of upland buffer will be created adyacent to the wetland to mitigate the placement of fin for the construction of the benn.
