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 71 Page 1 of 11 January 12, 2017 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.

The manhole or vault may be divided into multiple chambers where the first chamber acts as a presettling basin for removal of coarse sediment while the next chamber acts as the filter bay and houses the filter cartridges. A variety of configurations and media types are available from various manufacturers. Typical media filter components include: • Vault for flow storage and media housing • Inlet and outlet • Media filters Normal Expected Maintenance Media filters require routine maintenance to: remove accumulated materials such as sediment, trash, and debris; replace filter cartridges; and maintain integrity of any internal components such as weirs and piping. A summary table of standard inspection and maintenance indicators is provided within this Fact Sheet. Non-Standard Maintenance or BMP Failure The normal expected maintenance described above ensures the BMP functionality. Lapses in the normal expected maintenance can lead to clogging of the BMP and potentially blocking the storm drain system. If clogging is observed, the BMP is not performing as intended to protect downstream waterways from pollution and/or erosion. In addition, clogged BMPs can lead to flooding, standing water and mosquito breeding habitat. Maintenance is critical to ensure the flood protection capacity of the storm drain system is not compromised. If proper routine maintenance is not performed, corrective maintenance and increased inspection and maintenance will be required. For persistent clogging or presence of mosquitos, contact the [City Engineer] to determine a permanent solution. For example, adding pretreatment measures within the tributary area draining to the BMP to intercept sediment, trash, and debris. Pretreatment components, especially for sediment, will extend the life of the filter media. For mosquitos, a Vector Management Plan, prepared with concurrence from the County of San Diego Department of Environmental Health,may be required. Other Special Considerations Media filters are proprietary systems that include proprietary media that must be replaced as part of normal expected maintenance.They are typically installed underground and may require entry into the underground vault to perform the maintenance.The BMP owner is responsible to hire a maintenance operator qualified to service the units. The maintenance operator must obtain the appropriate filter media and/or any parts that need to be replaced. If maintenance conditions require maintenance personnel to enter the underground structure, the maintenance personnel must be trained and certified in confined space entry. To find a qualified maintenance operator,the BMP owner shall contact the manufacturer of the proprietary BMP. The design of media filters includes consideration of the specific.pollutants expected from the area tributary to the media filter and the specific pollutants of concern for the downstream waterways. Therefore, it is expected that the filter media selected during design of the project will not be substituted. If a need arises to substitute a different filter configuration or filter media,the[City Engineer] shall be contacted prior to any changes. FT-2 Page 1 of 6 January 12, 2017 FT-2 Media Filter SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR FT-2 MEDIA FILTER 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 Accumulation of sediment,litter,or debris. Remove and properly dispose of accumulated materials. • Inspect monthly. • Remove materials annually (minimum), or more The threshold for removal of materials depends on the frequently when BMP reaches manufacturer's specific type of proprietary filter and configuration and threshold for removal of materials in less than one' shall be based on the manufacturer's recommendation. year,or if accumulation blocks outlet.
