Stormwater Wetland 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.
Important maintenance procedures:
- Immediately following construction of the stormwater wetland,bi-weekly inspections will be
conducted and wetland plants will be watered bi-weekly until vegetation becomes established
(commonly six weeks).
- No portion of the stormwater wetland will be fertilized after the first initial fertilization that is
required to establish the wetland plants.
- Stable groundcover will be maintained in the drainage area to reduce the sediment load to the
wetland.
- Once a year,a dam safety expert should inspect the embankment.
After the stormwater wetland is established,I will inspect it monthly 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 will be kept in a known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired
immediately.
