Based on a re^’iew of aenal photographs, the wetland appears to have been excavated benveen 1953 and 1964, an assessment that was supported by obsen*ations of the w etland durmg the December 14, 2001 and June 6,2002 site visits by Kjolhaug Environmental Services Company, Inc. Dunng these visits, the wetland was ob$en*ed to consist of an open-w'ater pon^ which had very little emetgent vegetanon around the edges, and the uplands were mowed to the w*ater's edge. Water depths in the pond were assumed to be 1 to 2 feet. As shown on the anached grading plan, the applicant proposes to construct a small berm in the wetland along the western property line in order to provide substrate for the establishment of emergent herbaceous and woody wetland vegeudon. A break in the berm will maintain the existing drairugc of the wetland toward the southwest ui order to prevent changes to the pond's water level. The berm was detemuned to be necessary because the water depths along the western property line were too deep to allow woody vegetation to become established. The proposed project would reesublish vegetanon around poruons of the w*etland, and partially restore vegetation to the inner portions of the basin. The top elevation of the betm will be no more than 1.0 foot above the norrrul water level of the wetland, therefore, the project will result in no loss of wetland area. Although the project will parnally restore the excavated wetland, the placement of 2,135 square feet (sO of Ell maten.vl for the construction of the berm will be mingated through the creation of 2,135 sf of new wetland adjacent to the existing wetland, and the esubUshment of 11,787 sf of nanve.
