Immediately following construction of the storrnwater 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 iu required toestablish
the wetland plants.
Stable groundcover will be maintained in the drainage area to reduce the sediment load to the wetland.
- Once m year,u dam safety expert should inspect the embankment.
After the stormwater wetland is established, it shall be inspected monthly and within 24 hours after every storm event greater
