Bioretenton Maintenance Requirements `
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 bloretention 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.
Remove top layer of fill media when the pool does not drain quickly. Based on the media
specification, the pool should drain within 24 hours.
After the bioretention cell is established, it will be inspected quarterly and within 24 hours after every storm event
greater than 1.0 inches (or 1.6 inches if in a Coastal County). Records of operation and maintenance shall be kept
in a known set location and shall be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
