As the volume of fines, defined as either clay particles (less than 2 microns, or 0.002 or silt particles (between 2 and 50 microns, or 0.002 and 0.05 min) within a given soil mix TT) is increased, there is a possibility that those fines may be flushed or migrate downward through the soil mix with each runoff event and eventually fill or otherwise clog the void space randomly throughout the mix and create preferential flow paths. In the short term this can lead to short circuiting and reduced volume reduction and pollutant removal, and in the long term may clog the soil layer. This tendency is offset by addition and maintenance of appropriate amounts of soil organic matter which binds soil fines into larger non -mobile aggregates. • General Filter Media Physical Composition. The mineral soil texture of the bioretention soil mix should be loamy coarse sand with no more than 10% clay, no more than 20% silt + clay and at least 75% of the sand fraction should be coarse or very coarse sand. • To allow for appropriate Cation Exchange Capacity (CEC) and nutrient removal, the mix should contain at least 10% soil fines (slit + clay) while meeting the overall texture specification above. The particle size analysis must be conducted on the mineral fraction only or following appropriate treatments to remove organic matter before particle size analysis. • The Filter Media should contain 3% to 5% organic matter by conventional Walkley-Black soil organic matter determination method or similar analysis. Soil organic matter is expressed on a dry weight basis and does not include coarse particulate (visible) components. Version 2.0, January 1, 2013 Page 25 of 62 VA DCR STORMWATER DESIGN SPECIFICATION NO. 9 BIORETENTION • The overall particle size distribution of the mix will vary since the sand fraction may contain some finer sizes as will native topsoils if utilized. As stated previously, the goal of the mixture is to achieve the desired constant head permeability. Therefore, the filter media composition noted above serves as the target recipe for the three ingredients, while the ultimate performance goal is to achieve a verified soil permeability or hydraulic conductivity (Ksat) of 1 to 2 inches per hour (or 30 to 60 cm/day). • The following is the recommended composition of the three media ingredients: o Sand shall consist of silica based coarse aggregate, angular or round in shape and meet the mixture grain size distribution below. No substitutions of alternate materials such as diabase, calcium carbonate, rock dust or dolomitic sands are accepted. In particular, mica can make up no more than 5% of the total sand fraction. The sand fraction may also contain a limited amount of particles > 2.0 min and < 9.5 min per the table below, but the overall sand fraction must meet the specification of >75% being coarse or very coarse sand o Components Trash Rack Frame Angle Bottom woven/welded Steel Rod widthd Iron Flat Steel Wire Mesh for Grate up to 36" ly2"Xll/2"Xs/4" 1%"Xy4" 1/4•• between 38"-60" 2'X2"Xy4` 2"Xya" %"80" and larger 9"X3'lr' 30]i 5/a" i S E n V Trash Rack General Notes: Additional Notes - 3' minimum trash rack width is required where available.

Maintenance of permeable pavement is driven by annual inspections that evaluate the condition and performance of the practice. The following are suggested annual maintenance inspection points for permeable pavements: • The drawdown rate should be measured at the observation well for three (3) days following a storm event in excess of 1/2 inch in depth. If standing water is still observed in the well after three days, this is a clear sign that clogging is a problem. • Inspect the surface of the permeable pavement for evidence of sediment deposition, organic debris, staining or ponding that may indicate surface clogging. If any signs of clogging are noted, schedule a vacuum sweeper (no brooms or water spray) to remove deposited material. Then, test sections by pouring water from a five gallon bucket to ensure they work. • Inspect the structural integrity of the pavement surface, looking for signs of surface deterioration, such as slumping, cracking, spalling or broken pavers. Replace or repair affected areas, as necessary. • Check inlets, pretreatment cells and any flow diversion structures for sediment buildup and structural damage. Note if any sediment needs to be removed. • Inspect the condition of the observation well and make sure it is still capped. • Generally inspect any contributing drainage area for any controllable sources of sediment or erosion. An example maintenance inspection checklist for Permeable Pavement can be accessed in Appendix C of Chapter 9 of the Virginia Stormwater Management Handbook (2010). Based on inspection results, specific maintenance tasks will be triggered and scheduled to keep the facility in operating condition. PERMEABLE PAVEMENT MAINTENANCE REQUIREMENTS No Scale 9.2 First Year Maintenance Operations Successful establishment of bioretention areas requires that the following tasks be undertaken in the first year following installation: • Initial inspections. For the first 6 months following construction, the site should be inspected at least twice after storm events that exceed 1/2 inch of rainfall. • Spot Reseeding. Inspectors should look for bare or eroding areas in the contributing drainage area or around the bioretention area and make sure the are immediate) stabilized with grass cover. Y Y • Fertilization. One-time, spot fertilization may be needed for initial plantings. • Watering. Watering is needed once a week during the first 2 months, and then as needed during first growing season (April -October), depending on rainfall. • Remove and replace dead plants. Since up to 10% of the plant stock may die off in the first year, construction contracts should include a care and replacement warranty to ensure that vegetation is properly established and survives during the first growing season following construction. The typical thresholds below which replacement is required are 85% survival of plant material and 100% survival of trees. 9.3 Maintenance Inspections It is highly recommended that a spring maintenance inspection and cleanup be conducted at each bioretention area. The following is a list of some of the key maintenance problems to look for: • Check to see if 75% to 90% cover (mulch plus vegetative cover) has been achieved in the bed, and measure the depth of the remaining mulch. P 9 • Check for sediment buildup at curb cuts, gravel diaphragms or pavement edges that prevents flow from getting into the bed, and check for other signs of bypassing. • Check for any winter- or salt -killed vegetation, and replace it with hardier species. • Note presence of accumulated sand, sediment and trash in the pre-treatment cell or filter beds, and remove it. • Inspect bioretention side slopes and grass filter strips for evidence of any rill or gully erosion, and repair it. • Check the bioretention bed for evidence of mulch flotation, excessive ponding, dead plants or concentrated flows, and take appropriate remedial action. • Check inflow points for clogging, and remove any sediment. • Look for any bare soil or sediment sources in the contributing drainage area, and stabilize them immediately. • Check for clogged or slow -draining soil media, a crust formed on the top layer, inappropriate soil media, or other causes of insufficient filtering time, and restore proper filtration characteristics. • Example maintenance inspection checklists for Bioretention areas can be accessed in Appendix C of Chapter 9 of the Virginia Stormwater Management Handbook (2010). 9.4 Routine and Non -Routine Maintenance Tasks Maintenance of bioretention areas should be integrated into routine landscape maintenance tasks. If landscaping contractors will be expected to perform maintenance, their contracts should contain specifics on unique bioretention landscaping needs, such as maintaining elevation differences needed for ponding, proper mulching, sediment and trash removal, and limited use of fertilizers and pesticides. A customized maintenance schedule must be prepared for each bioretention facility, since the maintenance tasks will differ depending on the scale of bioretention, the landscaping template chosen, and the type of surface cover. A generalized summary of common maintenance tasks and their frequency is provided in Table 9.8. The most common non -routine maintenance problem involves standing water. If water remains on the surface for more than 48 hours after a storm, adjustments to the grading may be needed or underdrain repairs may be needed. The surface of the filter bed should also be checked for accumulated sediment or a fine crust that builds up after the first several storm events. There are several methods that can be used to rehabilitate the filter (try the easiest things first, as listed below): • Open the underdrain observation well or cleanout and pour in water to verify that the underdrains are functioning and not clogged or otherwise in need of repair. The purpose of this check is to see if there is standing water all the way down through the soil. If there is standing water on top, but not in the underdrain, then there is a clogged soil layer. If the underdrain and stand pipe indicates standing water, then the underdrain must be clogged and will need to be snaked. • Remove accumulated sediment and till 2 to 3 inches of sand into the upper 8 to 12 inches of soil. • Install sand wicks from 3 inches below the surface to the underdrain layer. Sand wicks can be installed by excavating or augering (using a tree auger or similar tool) down to the gravel storage zone to create vertical columns which are then filled with a clean open -graded coarse sand material (coarse sand mix similar to the gradation used for the soil media). A sufficient number of wick drains of sufficient dimension should be installed to meet the design dewatering time for the facility. • Last resort - remove and replace some or all of the soil media. Table 9.8. Suaaested Annual Maintenance Activities for Bioretention Maintenance Tasks Frequency • Mowing of grass filter strips and Bioretention turf cover At least 4 times a year • Spot weeding, erosion repair, trash removal, and mulch raking Twice during growing season At Add reinforcement planting to maintain desired the vegetation density As needed • Remove invasive plants using recommended control methods • Stabilize the contributing drainage area to prevent erosion • Spring inspection and cleanup • Supplement mulch to maintain a 3 inch layer Annually • Prune trees and shrubs • Remove sediment in re -treatment cells and inflow points Once every 2 to 3 years • Replace the mulch layer Every 3 years BIORETENTION FACILITY MAINTENANCE REQUIREMENTS No Scale Inspection Activities Suggested Schedule • Alter several storm events or an extreme storm event, inspect for: signs of clogging of the inlet or outlet structures and sediment accumulation. As Needed • Inspect for: trash and debris. clogging of the outlet structures and any pilot channels; excessive erosion; sediment accumulation in the basin and inletloutlet structures: tree growth on dam or embankment: the presence of burrowing animals; standing water where there should be Semi-annually none; vigor and density of the grass turf on the basin side slopes and floor. differential settlement; cracking: leakage: and slope stability. • Inspect that the outlet structures, pipes, and dowTtstream and pilot channels arc free of debris and arc operational. • Note signs of pollution, such as oil sheens, discolored water, or unpleasant odors. Annually • Check for sediment accumulation in the facility. • Check for proper operation of control gates, valves or other mechanical devices. Maintenance Activities Suggested Schedule • Pcrform structural repairs to inlet and outlets Monthly or as needed • Clean and remove debris from inlet and outlet structures. • Repair damage to inlet and outlet structures, control gates, valves, or other mechanical devices; repair undercut or eroded areas. As Needed • Monitor sediment accumulations, and remove sediment when pond volume has become reduced significantly.

SLOPEMASTER features the durable white clover Durana which is a medium -leafed, intermediate type white clover containing as many as 97 stolons per sq. foot which will secure most erodable soils. Durana is a superior white clover that is persistent and will fixate up to 150 lbs of atmospheric nitrogen per acre per year. The Nitrogen fixation by Durana will provide enrichment to a stand of low maintenance cool & warm season turfgmss. Durana is durable and you can count on it to compliment a stand of tall fescue or bermuda with lespedeza to maintain a long stand life. SLOPEMASTER is also treated with Pennington's exclusive GermMax technology for enhanced establishment. Characteristics: • Extremely durable erosion control mixture • Aggressive growth to provide complete ground cover • Contains perennial seed that establish quickly and last for years • Durana White Clover establishes stoloniforus growth to hold soils in place • Durana White Clover fixates atmospheric Nitrogen for reduced fertilizer requirements Where toplant. Jb Primary Adaptation ] Adapted in some sites Establishment: SLOPEMASTER can be planted by drilling, broadcasting, or hydraulic seeding. Planting can be made throughout the year when mixed with companion grasses that are suitable with planting dates, i.e. tall fescue in the fall or bermudagrass in the spring. Planting depth should be no more than inch (6.35 rum) for many stand failures result from planting to deep. Liming to a pH of 6.0 and providing adequate potassium and phosphorus are necessary to ensure a productive stand. Soil testing is highly recommended.
