Biofiltration facilities have limited or no infiltration.They are typically designed to provide enough hydraulic head to move flows through the underdrain connection to the storm.drain system. Typical biofiltration 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) • Impermeable liner or uncompacted native soils at the bottom of the facility • Overflow structure Normal Expected Maintenance Biofiltration 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. • 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. BF-1 Page 1 of 11 January 12,2017 BF-1 Biofiltration Other Special Considerations Biofiltration 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. BF-1 Page 2 of 11 January 12,2017 BF-1 Biofiltration SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR BF-1 BIOFILTRATION 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.

Cisterns can be aboveground or below ground systems. Typical cistern components include: • Storage container,barrel or tank for holding captured flows • Inlet and associated valves and piping • Outlet and associated valves and piping • Overflow outlet • Access riser or tank serviceway(i.e.,access for underground and above-ground cisterns) • Optional pump • Optional first flush diverters • Optional debris screen or pretreatment BMP(e.g.,roof drain filter,drainage inlet insert) • Optional roof,supports,foundation,level indicator,and other accessories Normal Expected Maintenance Cisterns can be'expected to accumulate sediment and debris that is small enough to pass through the inlet into.the storage container. Larger debris such as leaves or trash may accumulate at the inlet.While the storage container is generally a permanent structure, ancillary parts. including valves, piping, screens, level indicators, and other accessories will wear and require occasional replacement. Maintenance of a cistern generally involves: removing accumulated sediment and debris from the inlet and storage container on a routine basis; and replacement of ancillary parts on an as-needed basis. A summary table of standard inspection and maintenance indicators is provided within this Fact Sheet. If the system as'a whole includes a pump or other electrical equipment, maintenance of the equipment shall be based on the manufacturer's recommended maintenance plan. 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 inlet is found to be obstructed at every inspection such that storm water bypasses the cistern.The cistern is not functioning properly if it is not capturing storm.water.. This would require addition of ancillary features to protect the inlet, or pretreatment measures within the watershed draining to the cistern to intercept larger debris,such as screens on roof gutters,or drainage inserts within catch basins. Increase the frequency of inspection until the issue is resolved. • Accumulation of sediment within one year is greater than 25%of the volume of the cistern.This means the sediment load from the tributary drainage area has diminished the storage volume of the cistern and the cistern will not capture the required volume of storm water. This would require pretreatment measures within the tributary area draining to the cistern to intercept sediment. • The cistern is not drained between storm events: If the cistern is not drained between storm events, the storage volume will be diminished and the cistern will not capture the required volume of storm water from subsequent storms. This would require implementation of practices onsite to drain and use the stored water,or a different BMP if onsite use cannot be reliably sustained. HU-1 Page 1 of 8 January 12,2017 H U-1 Cistern SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR HU-1 CISTERN 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,propertyowners 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.
