Wet Detention Pond Maintenance Requirements
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one
is provided
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 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 drain 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 1 5 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
