They propose to excavate the northwesterly end of that <br />wetland to create a pond approximately 120' in length and about 60' in <br />width, or about. 1/4 of the wetland area <br />The grading plan indicates that spoils will be placed alor,, the east <br />and south sides of the existing driveway. <br />The applicants' designer has calculated the cut anu' rill volumes, each <br />at about 1,000 cubic yards, hence it is unlikely that any significant <br />amounts of fill will enter or leave the site. He has also calculated the <br />before and after storage volumes and is noting that while storage will <br />decrease by 9%, the 100 year rainfall eve.it will still be retained. <br />
