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, 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. BMP element: Potential problem_ How I will remediate the problem: Entire BMP Trash/debris is present. Remove the trash/debris.
