Stormweter Wetland Maintenance Requirements
Important operation and maintenance procedures:
Immediately following construction of the stormwater wetland,conduct bi-weekly inspections and water wetland plants bi-
weekly until vegetation becomes established(commonly six weel6).
Before and immediately after plant installation,monitor water level and adjust to ensure that plants are not completely
inundated.
No portion of the stormwater wetland will be fertilized after the initial fertilization that is required to establish the wetland
plants.
- Stable g roundcover will be maintained in the drainage area to reduce the sediment load to the wetland.
At least once annually,a dam safety expert will inspect the embankment.Any problems that are found will be repaired
- immediately.
After the wetland is established,it shall be inspected quarterlyand within 24 hours after everystorm event greater than 1.0 inches(or 1.5
inches if in a Coastal County). Records of operation and maintenance shall be kept in a(mown set location and shall be available upon
request.
Inspection activities shall be performed as follows.Any problems that are found shall be repaired immediately.
