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): ❑ does ® does not incorporate a vegetated filter at the outlet. 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 vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly 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 basin. — 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).

This maintenance record will be kept in a Iog in a known set Iocation. 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 filter strip is established, any newly planted vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). — Once a year, the filter strip will be reseeded to maintain a dense growth of vegetation — Stable groundcover will be maintained in the drainage area to reduce the sediment load to the vegetation. — Two to three times a year, grass filter strips will be mowed and the clippings harvested to promote the growth of thick vegetation with optimum pollutant removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and may be allowed to grow as tall as 12 inches depending on aesthetic requirements (NIPC,1993). Forested filter strips do not require this type of maintenance. — Once a year, the soil will be aerated if necessary. — Once a year, soil pH will be tested and lime will be added if necessary. After the filter strip is established, it will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inch (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: Potentialproblem: How I will remediate theproblem: The entire filter strip Trash/debris is present.

The level Iip is cracked, settled, undercut, eroded or otherwise damaged. There is erosion around the end of the level spreader that shows stormwater has bypassed it. Trees or shrubs have begun to grow on the swale or just _downslope of the level lip.^ Areas of bare soil and/or erosive gullies have formed. Turf reinforcement is damaged or ripap is rolling downhill. Grass is too short or too long if applicable). Areas of bare soil and/or erosive gullies have formed. Sediment is building up on the filter strip. Plants are desiccated Plants are dead, diseased or dying. Nuisance vegetation is choking out desirable species. Erosion or other signs of damage have occurred at the outlet. How I will remediate the problem: Remove the sediment and dispose of it off -site. Repair or replace lip. Regrade the soil to create a berm that is higher than the level lip, and then plant a ground cover and water until it is established. Provide lime and a one-time fertilizer appacanon. Remove them. Regrade the soil if necessary to remove the gully, and then reestablish proper erosion control. Study the site to see if a larger bypass channel is needed (enlarge if necessary). After this, reestablish the erosion control material. Maintain grass at a height of approximatel three to six inches. Regrade the soil if necessary to remove the gully, and then plant a ground cover and water until it is established. Provide lime and a one-time fertilizer application. Remove the sediment acid restabilize the soil with vegetation if necessary. Provide lime and a one- time fertilizer application. Provide additional irrigation and Fertilizer as needed. Determine the source of the problem: soils, hydrology, disease, etc. Remedy the problem and replace plants. Provide a one-time fertilizer application. Remove vegetation by hand if possible. if pesticide is used, do not allow it to get into the receiving water.
