It is anticipated <br />the high water level will be at an elevation cf 873. <br />Consequently, some filling of the wetlands may be required to <br />construct the trail. Since the land dedicated for park is <br />less than i0%, the balance will have to be paid in cash. <br /> <br />Easements for the detention ponds and drainageways are not <br />shown on the plans. High water elevations are needed for all <br />the ponds along with the grading plan for the ponding areas <br />to provide for storage of a 100 year sto.~m. <br /> <br />As previously stated, none of the detention areas have <br />outlets; therefore, the building elevations of the lowest <br />floor should be set at least three feet above the highest <br />known water levels as stated in the Environmental Protection <br />Ordinance. <br /> <br />ZZZ Monroe Street <br />Anoka, Minnesota 55303 <br /> <br />612_/427-5860 <br /> <br />Fax 612/427-3401 <br /> <br />Eugene I.
