Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on tlus 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 BMW
Important maintenance procedures
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks)
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation
— The vegetation in and around the basin will be maintained at a height of
approximately six inches
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 10 inches (or 15 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 inimediately

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
— 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
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 10 inches (or 15 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
