IT k The proposed new wetland areas will be created by excavatbg down from the existing contours adjacent to the wetland as shown on Figure 3. The new wetland areas are projected to become semipennanently*flooded and seasona]fy*flooded wetland (FUBF/PEMIC) fringes of the existmg wetland basin, with the berm expected to become saturated forested (PFOlB) wetland. A combination of native, non-invasive seed mix and seedlings/plugs similar to the mix in Attachment A wiU be established dong 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 nu^le will be planted on the proposed berm, depending upon availability. The proposed upland buffer areas will be a minimum of 16.S feet wide along the southern and e^em sides of the wetland, and a minimum of 25 feet wide abng the northern edge of the wetland. A native, non-invasive plant community will be established in the proposed upland buffer areas using a mix similar to that iiKluded in Attachment A. The upland buffer area along the northern edge of the wetland 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 earthen berm, ^^hkh will be used to establish emergent herbaceous and woody vegetatioa In addition, 2,135 sf of new wetland and 11,787 sf of upland buffer will be created adjacent to the wetland to mitigate the placement of fill for the construction of the berm. If you have any questions or comments on the proposed plan, please fisel free to call Mark Kjolhaug or myself. ‘M M I../ r
