Check and clear the orifice of any obstructions such that drawdo,�vn of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 5,1.5 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads 5.25 feet in the forebay, the sediment shall be removed. t -- - o r 3D Z ti,--------- --- - ��:: FOREBAY BASIN DIAGRAM (fill in the blanks) Permanent Pool F.Ievation s Sediment Rcmoval llevation 3O'�� ` •, , l Bottom Elevation MAIN POND 5.
