These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important operation and maintenance procedures: — Immediately after the bioretention cell is established, the plants will be watered twice weekly if needed until the plants become established (commonly six weeks). — Snow, mulch or any other material will NEVER be piled on the surface of the bioretention cell. — Heavy equipment will NEVER be driven over the bioretention cell. — Special care will be taken to prevent sediment from entering the bioretention cell. — Once a year, a soil test of the soil media will be conducted. After the bioretention cell 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).

Sediment has accumulated to a depth greater than three inches. Erosion has occurred. Weeds are present. Best professional practices show that pruning is needed to maintain optimal plant health. Plants are dead, diseased or dying. Tree stakes/wires are present six months after planting. Mulch is breaking down or has floated away. Soils and/or mulch are clogged with sediment. An annual soil test shows that pf-I has dropped or heavy metals have accumulated in the soil media. I -low I will remediate the problem: Regrade if necessary to route all flow to the pretreatment area. Restabilize the area after grading. Search for the source of the sediment and remedy the problem if possible. Remove the sediment and restabilize the pretreatment area. Provide additional erosion protection such as reinforced turf matting or riprap if needed to prevent future erosion problems. Remove the weeds, preferably by hand. Prune according to best professional practices. Determine the source of the problem: soils, hydrology, disease, etc. Remedy the problem and replace plants. Provide a one-time fertilizer application to establish the ground cover if a soil test indicates it is necessary. Remove tree stake/wires (which can kill the tree if not removed). Spot mulch if there are only random void areas. Replace whole mulch layer if necessary. Remove the remaining much and replace with triple shredded hard wood mulch at a maximum depth of three inches. Determine the extent of the clogging - remove and replace either just the top layers or the entire media as needed. Dispose of the spoil in an appropriate off -site location. Use triple shredded hard wood mulch at a maximum depth of three inches. Search for the source of the sediment and remedy the problem if possible. Dolomitic lime shall be applied as recommended per the soil test and toxic soils shall be removed, disposed of properly and replaced with new pianting media.
