PLANTINGS
No additional maintenance is recommended at this time.
Several of the plants provided with the original construction of the facility appear to have
died. These plants should be removed and replaced.
Comments:
The facility appears to have become overgrown. As such, the vegetation in the
facility should be thinned out.
Comments:
Additional items/comments:
BERM (SMALL DAM EMBANKMENT)
No additional maintenance is recommended at this time.
The berm was not constructed properly. The berm should be reconstructed to the
required height and with the required material.
Comments:
A portion of the berm has “blown out” (e.g., eroded). The berm should be repaired.
Along with the repair, the installation of an armored spillway may require that the
berm be constructed to a height approximately 6-inches above the height specified in
the approved Construction Drawings.
Comments:
Additional items/comments:
INFLOW CHANNELS/PIPES/SLOPES
No additional maintenance is recommended at this time.
The inlet areas have eroded. These eroded areas should be repaired.
Comments:
Trash and debris are in the forebay/sediment basin. This material should be removed. If
the facility is fed by concentrated inlets and there is not a forebay or sediment basin, one
should be considered.
Comments:
Approximately 50% (or more) of the forebay/sediment basin has been filled with sediment.
This material should be removed.
Comments:
It appears that the by-pass/diversion structure is malfunctioning. Any trash, sediment, or
debris blocking the entry or passage of storm slows through the structure should be removed.
Comments:
Additional items/comments:
PRINCIPAL SPILLWAY PIPE (PSP)
No additional maintenance is recommended at this time.
The PSP is blocked. The blockage should be removed.
Comments:
One or more joints of the PSP are leaking.
Comments:
One or more sections of pipe have settled to a point where the integrity of the dam may be
threatened. These sections of pipe may need to be replaced.
Comments:
Additional items/comments:
OUTFALL
Not applicable.
No additional maintenance is recommended at this time.
The outfall area is eroding. The eroded area should be repaired.
Comments:
The outfall area is blocked. This blockage should be removed.
Comments:
Additional items/comments:
OUTLET STRUCTURE
No additional maintenance is recommended at this time.
The low-level orifice/inverted siphon is blocked. This blockage should be removed. A debris
cage is/is not (highlighted) recommended [disregard comment if a trash-rack is already
present].
Comments:
The outlet structure is filled with excess material (debris, trash, rock, etc.). This material
should be removed. A top trashrack is/is not recommended [disregard comment if a
trashrack is already present].
Comments:
The top trashrack/anti-vortex device is damaged. The trash-rack/anti –vortex device should
be repaired or replaced.
Comments:
The outlet structure is damaged/deteriorated. The outlet structure should be repaired or
replaced.
Comments:
Additional items/comments:
BIORETENTION AREA & UNDER DRAINS (PLANTINGS EXCLUDED)
No additional maintenance is recommended at this time.
The mulch layer has deteriorated or washed away. This mulch layer should be replaced
with a 3-inch deep layer of durable hammered hardwood mulch and should be spread
uniformly over the entire area or replaced every 3-years and touched up (raked) annually.
Comments:
Areas of erosion were noted in the floor of the bioretention area. These areas should be
repaired.
Comments:
BIORETENTION AREA & UNDER DRAINS (PLANTINGS EXCLUDED) CONTINUED
The bioretention area is holding water (e.g., for more than 40-hours after a rain event).
Comments:
It appears that the soil mix was not installed properly (e.g., either the required soil mix was
not used or it was not installed to the correct depth). If it is determined that the soil mix was
constructed improperly, the bioretention area will need to be reconstructed to the plan and
specifications contained in the approved Construction Drawings.
Comments:
It appears that the relief pipes (e.g., under drains) proposed in the approved construction
drawings were not installed. If it is determined that these drains were not installed, the
bioretention area may need to be reconstructed. The relief drains were proposed to
mitigate the effects of the poorly draining soils anticipated under the subject facility. If it
appears, however, that the facility is functioning adequately and infiltrating the treated
drainage into the underlying soil, reconstruction will not be required. If relief drains were not
proposed in the Construction Drawings, and the facility appears to have been functioning
more like a wetland, official conversion of the facility from a bioretention area to a
stormwater wetland may be appropriate. In such instances, consultation with the City of
Fairfield Public Works Director is recommended.
