INSPECTION and MAINTENANCE

Routine inspection should be conducted within 24 hrs of a runoff event or as designated by the regulating authority. Level spreaders should be regularly inspected to make sure they maintain their shape and are adequately converting concentrated fows to sheet fow. If ponding becomes excessive sediment or debris removal may be necessary, or the forebay may need to be redesigned to allow for greater water volume capture from catchment area. If undermining of Level spreader occurs, backflling or reinstallation may be required. If erosion occurs after leaving the Level spreader, erosion control blankets, turf reinforcement mats, rip rap, or longer Level spreader may be required.

1. The Contractor shall maintain the Level spreader in a functional condition at all times and it shall be routinely inspected.

2. If the Level spreader has been damaged, it shall be repaired, or replaced if beyond repair.

3. The Contractor shall remove sediment and debris around Level spreader and within the forebay when accumulation has reached 1/2 of the effective height of the Soxx tm or when 1/3 of forebay volume capacity has been displaced.

4. If erosion has occurred in the vegetated zone, erosion control blankets, turf reinforcement mats, regrading, and revegetation may be necessary.

5. Vegetation zone may be regularly mowed to maintain low and dense growing vegetation.
