Biofiltration with Partial Retention
BMP MAINTENANCE FACT SHEET
FOR
STRUCTURAL BMP PR-1 BIOFILTRATION WITH PARTIAL RETENTION
Biofiltration with partial retention facilities are vegetated surface water systems that filter water through
vegetation and soil or engineered media prior to infiltrating into native soils, discharge via underdrain, or overflow
to the downstream conveyance system. These BMPs have an elevated underdrain discharge point that creates
storage capacity in the aggregate storage layer.Typical biofiltration with partial retention components include:
• Inflow distribution mechanisms(e.g.,perimeter flow spreader or filter strips)
• Energy dissipation mechanism for concentrated inflows(e.g.,splash blocks or riprap)
• Shallow surface ponding for captured flows
• Side slope and basin bottom vegetation selected based on climate and ponding depth
• Non-floating mulch layer
• Media layer(planting mix or engineered media)capable of supporting vegetation growth
• Filter course layer consisting of aggregate to prevent the migration of fines into uncompacted native soils
or the aggregate storage layer
• Aggregate storage layer with underdrain(s)
• Uncompacted native soils at the bottom of the facility
• Overflow structure
Normal Expected Maintenance
Biofiltration with partial retention requires routine maintenance to: remove accumulated materials such as
sediment, trash or debris; maintain vegetation health; maintain infiltration capacity of the media layer; replenish
mulch; and maintain integrity of side slopes, inlets, energy dissipators, and outlets. A summary table of standard
inspection and maintenance indicators is provided within this Fact Sheet.
Non-Standard Maintenance or BMP Failure
If any of the following scenarios are observed, the BMP is not performing as intended to protect downstream
waterways from pollution and/or erosion. Corrective maintenance, increased inspection and maintenance, BMP
replacement,or a different BMP type will be required.
• The BMP is not drained between storm events. Surface ponding longer than approximately 24 hours
following a storm event may be detrimental to vegetation health, and surface ponding longer than
approximately 96 hours following a storm event poses a risk of vector(mosquito) breeding. Poor drainage
can result from clogging of the media layer, filter course, aggregate storage layer, underdrain, or outlet
structure.The specific cause of the drainage issue must be determined and corrected.
• Sediment, trash, or debris accumulation greater than 25% of the surface ponding volume within one
month. This means the load from the tributary drainage area is too high, reducing BMP function or
clogging the BMP. This would require pretreatment measures within the tributary area draining to the
BMP to intercept the materials. Pretreatment components, especially for sediment,will extend the life of
components that are more expensive to replace such as media,filter course,and aggregate layers.

PR-1
Biofiltration with Partial Retention
• Erosion due to concentrated storm water runoff flow that is not readily corrected by adding erosion
control blankets, adding stone at flow entry points, or minor re-grading to restore proper drainage
according to the original plan. If the issue is not corrected by restoring the BMP to the original plan and
grade,the[City Engineer] shall be contacted prior to any additional repairs or reconstruction.
Other Special Considerations
Biofiltration with partial retention is a vegetated structural BMP. Vegetated structural BMPs that are constructed
in the vicinity of, or connected to, an existing jurisdictional water or wetland could inadvertently result in creation
of expanded waters or wetlands. As such, vegetated structural BMPs have the potential to come under the
jurisdiction of the United States Army Corps of Engineers,SDRWQCB, California Department of Fish and Wildlife,or
the United States Fish and Wildlife Service. This could result in the need for specific resource agency permits and
costly mitigation to perform maintenance of the structural BMP.Along with proper placement of a structural BMP,
routine maintenance is key to preventing this scenario.

SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR PR-1 BIOFILTRATION WITH PARTIAL RETENTION
The property owner is responsible to ensure inspection,operation and maintenance of permanent BMPs on their property unless responsibility has been formally transferred to
an agency,community facilities district,homeowners association,property owners association,or other special district.
Maintenance frequencies listed in this table are average/typical frequencies.Actual maintenance needs are site-specific,and maintenance may be required more frequently.
Maintenance must be performed whenever needed,based on maintenance indicators presented in this table.The BMP owner is responsible for conducting regular inspections
to see when maintenance is needed based on the maintenance indicators.During the first year of operation of a structural BMP,inspection is recommended at least once prior
to August 31 and then monthly from September through May.Inspection during a storm event is also recommended.After the initial period of frequent inspections,the
minimum inspection and maintenance frequency can be determined based on the results of the first year inspections.
Threshold/Indicator Maintenance Action Typical Maintenance Frequency

bottom elevation,then the materials must be removed when there is 3 inches of accumulation—this should be marked on the outflow structure).
