I will keep a maintenance record on this BMP This maintenance record will be kept in a
log in a known set location Any deficient BW elements noted in the inspection will be
corrected, repaired or replaced m=ediately These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided
This system (check one):
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures
- Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks)
- No portion of the wet detention pond should be fertilized after the first curial
fertilization that is required to establish the plants on the vegetated shelf
Stable groundcover should be mamtamed in the drainage area to reduce the
sediment load to the wet detention basin
If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency dram should be minimized to the
maximum extent practical
Once a year, a dam safety expert should inspect the embankment
After the wet detention pond is established, it should be inspected once a m � E �,�
within 24 hours after every storm event greater than 10 inches (or 15 inc in a
Coastal County) Records of operation and maintenance should be kept in ffnMs2t4 2012
location and must be available upon request.
