Mauntdnance activities shall be performed as follows
After every significant runoff producing rainfall event and at least nnontlnly
a Inspect the wet detention basin system for sediment a(-CUtnuiatlon, eiosion, trash accumulation, vegetated
cover, and general condition
b Check and clear the orifice of any obste uctions such that drawdown of tine 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 coves
to maintain a maximum height of six inches, and remove trash as needed
3 Inspect and repair the collection system (i a catch banns, piping, swales, ripiap, etc ) quarterly to maintain piopei
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 stieam, etc )
The mcasuring device used to determine the sedlnnent elevation shall be such that it will give an accurate depth
icading and not readily penetrate into accumulated sediments
When the permanent pool depth reads 4 13 feet in the main pond, the sediment shall be removed
When the permanent pool depth reads 338 feet in the forebay, the sediment shall be removed

6 It the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical
7 All components of the wet detention basin system shall be maintained in good working order
