Inspect storm sewer outfalls on an annual basis for evidence of scouring <br />or the presence of significant deposition of silt. Scouring pro b1em areas <br />will be noted and stabilized. In areas where silt deposition is evident, <br />which is indicative of significant erosion upstream, an inspection of the <br />upstream watershed will be made to identify the source of erosion. Once <br />this erosion problem is determined suitable corrective measure will then <br />be undertaken to correct the problem. <br /> <br />Ponds and Wetlands <br /> <br />]. Visually inspect storm water retention and detention ponds every two <br />years to determine if the pond is performing adequately. <br /> <br />2. Conduct a pond bottom survey every ten years to determine required <br />"dead storage" volume. Once a pond has lost half of its dead storage <br />volume, the accumulated sediment should be removed from the pond. <br /> <br />3. A pond maintenance agreement with private pond owners shall be <br />required. This will ensure that private ponds are kept in good operating <br />condition and that routine maintenance occurs. See Appendix M for an <br />example agreement. <br /> <br />City of Arden Hills. Minnesota <br />Local Stormwater Management Plan <br /> <br />A.ARDEN0101.00 <br />Page 32 <br />
