Design Summary, Page 2 cf 2 Permit Number: (to be provided big DIt"Q) Drainage Area Number: Wet Detention Basin Operation and Maintenance Agreement I will keep a maintenance record on this BIvIP. 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. The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one): CD ❑ does ® does not incorporate a vegetated filter at the outlet. m y This system (check one): ❑ does ® does not incorporate pretreatment other than a forebay. Important maintenance procedures: — immediately after the wet detention basin is established, the plants on the l vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (conurtonly six weeks). — No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. — Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basil. — If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. — Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected 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 should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. BMP element: Potentialproblem: How 1 will remediate theproblem: The entire BMP Trash/debris is present. Remove the trash/debris.
