Project Design Summary, Page 3 of 3 Permit Number: (to be provided by DWQ) Drainage Area Number: 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 after the stormwater wetland is established, the wetland plants will be watered twice weekly if needed until the plants become 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 wet detention basin. - Once a year, a dam safety expert will inspect the embankment. After the wet detention pond is established, I will inspect it once a month 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: The entire BMP Trash/ debris is resent. Remove the trash/ debris.
