Wet Detention Basin Operation and Maintenance Agreement
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 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.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

General Requirements
Yes Sizing shall take into account all runoff at ultimate build out, including off -site drainage
Yes Vegetated slopes shall be no steeper than 3:1.
Yes BMP shall be located in a recorded drainage easement with access to a public ROW.
Yes Per supplement form the wet pond is designed for 85%TSS removal. Basin discharge shall be evenly
distributed across a minimum 30 feet long vegetative filter strip unless it is designed to remove 90%TSS.
Yes The design storage shall be above the permanent pool.
Yes Discharge rate of the treatment volume shall completely draw down between 2 and 5 days.
Yes The average depth of the permanent pool shall be a minimum of 3 feet.
Yes Permanent pool surface area shall be determined using Tables 10-1, 10-2, 10-3, and 10-4.
Yes The flow within the pond shall not short circuit the pond.
Yes BMP shall be designed with a forebay.
Yes BMP shall not be located to produce adverse impacts on water levels in adjacent wetlands.
'Yes A minimum 10-fout wide vegetated shelf shaii be iiisiaiieu around the perimeter. The inside edge of the
shelf shall be 6" below the permanent pool elevation; the outside edge of the shelf shall be 6" above the
permanent pool elevation.
Yes The forebay volume should be about 20% of the total permanent pool volume, leaving about 80% of the
design volume in the main pool.
Yes. Freeboard shall be a minimum of 1 foot above the maximum stage of the basin.
Sk' rf : a he permanent pool elevation shall be within 6 inches (plus or minus) of the SHv` T elevation..
