BR Ponding Area Examine the entire Bioretention surface and side slopes Problem (Check if Present) Follow-Up Actions Add new mulch to a total depth (including any existing mulch that is left) of 2 to 3 inches. The mulch should be shredded hardwood mulch that is less likely to float away during rainstorms. Avoid adding too much mulch so that inlets are obstructed or certain areas become higher than the rest of the Bioretention surface. Other: Mulch (if used) needs to be replaced or replenished. The mulch layer had decomposed or is less than 1-inch thick. Use a shovel to scoop out minor areas of sediment or grit, especially in the spring after winter sanding materials may wash in and accumulate. Dispose of the material where it cannot re-enter the Bioretention cell . If removing the material creates a hole or low area, fill with soil mix that matches original mix and cover with mulch so that the Bioretention surface area is as flat as possible. Remove trash, vegetative debris, and other undesirable materials. Other: Kick-Out to Level 2 Inspection: Sediment has accumulated more than 2- inches deep and covers 25% or more of the Bioretention surface. Kick-Out to Level 2 Inspection: The Bioretention cell is too densely vegetated to assess sediment accumulation or ponding; Minor areas of sediment, grit, trash, or other see BR-4, Vegetation. debris are accumulating on the bottom.
