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 BMP elements noted in the inspection will be
corrected, repaired or replaced immediately 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 estabushed (commonly six weeks)
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf
- Stable groundcover should be maintained 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 month and
within 24 hours after every storm event greater than 1.0 inches (or 15 inches if in a
Coastal County) Records of operation and maintenance should be kept in a known set
location and must be available upon request
Inspection activities shall be performed as follows Any problems that are found shall
