Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. 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.
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.
Fleavy 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. Records of operation and maintenance will be
kept in a known set location and will be available upon request.
Annually, by May 31, an inspection shall be completed by a qualified professional and
submitted to the City of Burlington.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired
immediately.
