( STORMWATER SITG PLAN MAY 26, 2006 <br />MADISON COM�tUNI7l' CHURCH PAGE 20 <br />I <br />Storm Drain Inlet Protection <br />1 For systems using filter fabric: inspections should be made on a regular basis, especially after <br />large storm events. If the fabric becomes clogged, it should be replaced. if a fabric bag insert is <br />used, sediment should be removed �vhen it fills approximatcly one half of the storage dcpth. For <br />� systems using stonc filtcrs, if thc stone becomes clogged with se�iment, the stones must be <br />pulled away from thc inlct and dcanal or replaced. Since cleaning of gravel at a cons;ruction sitc <br />may be difficult, an altemative approach would be to use the clogged stone as fill and put fresh <br />( :,tone around the inlet. <br />Temporary Sediment Pond (or Basin) <br />I Inspections should be madc regularly, especially atler large stonn events. Sediment should he <br />rcmoved when it fills one half of the pond's total sediment storagc area. The effectiveness of a <br />sediment pond is based Iess on its sizc than on regular sediment removal. The riser of o�erflow <br />Ishall be inspecteci at the same interval as the pond and cleared of any debris or sediment build up. <br />STORM DRAIN SYSTEM MAINTENANCE <br />Gencral: <br />I I.
