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 expertshould inspectthe embankment.
After the stormwater wetland is established, it shall be inspected 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.
