Infiltration Basin 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 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 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set Iocation
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall

Potential problem:
Sediment has accumulated
and reduced the depth to 75%
of the original design depth.
Erosion has occurred or
riprap is displaced.
Weeds are present.
A visible layer of sediment
has accumulated.
Water is standing more than
5 days after a storm event.
Weeds and noxious plants are
growing in the niain

Shrubs or trees have started
to grow on the embankment.
An annual inspection by an
appropriate professional
shows that the embankment
needs repair.
Clogging has occurred
The outlet device is damaged
Erosion or other signs of
damage have occurred at the
outlet.
How I will remediate the problem:
Search for the source of the
sediment and remedy the problem if
possible. Remove the sediment and
dispose of it in a location where it
will not cause impacts to streams or
the 13MI'.
Provide additional erosion
protection such as reinforced turf
niatting or riprap if needed to
prevent future erosion problems.
Remove the weeds, preferably by
hand. If pesticides are used, wipe
them on the plants rather than
Search for the source of the
sedimentand remedy the problem if
possible. Remove the sediment and
dispose of it in a location where it
will not cause impacts to streams or

was removed in the process.
Revegetate disturbed areas
immediately.
Replace the top few inches of filter
media and see if this corrects the
standing water problem. If so,
revegetate immediately. If not,
consult an appropriate professional
for a more extensive repair.
Remove the plants by hand or by
wiping them with pesticide (do not
