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. DETENTION PIPE 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 they are immediately stabilized with grass cover. • 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. • 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 too]) 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.& Suggested Annual Maintenance Activities for Bioretention Maintenance Tasks Frequency • Mowing of grass filter sins and bioretention turf cover At least 4 times a year • Sot weeding, erosion repair. trash removal, and mulch raking Twice during growingseason to 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 • Sprang inspection and cleanup • Supplement mulch to maintain a 3 inch layer Annually • Prune bees and shrubs • Remove sediment in re -treatment cells andinflow lots Once every2 to 3 yeare • Replace the mulch la er Eve 3 ears BIORETENTION FACILITY MAINTENANCE REQUIREMENTS No Scale In: cuun Activitics Su tested Schedule • After several storm events or an extreme storm event, inspect for: sign% of clogging of the inlet or outlet structures and sediment accumulation.

SUBMITTAL DATE 1 FINAL SITE PLAN & WPO PLAN SUBMISSION 10.AUG.2020 LANDSCAPE PLAN LlnO CONCEPT PLANT SCHEDULE Professional Erosion Control Seed Mixture SLOPEMASTER is a seed mixture specifically designed for erosion control where rapid establishment is a necessity with little follow up maintenance. 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. Duran 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 turfgrass. 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 GermAlax 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 • Duraua White Clover establishes stoloniforus growth to hold soils in place • Duran White Clover fixates atmospheric Nitrogen for reduced fertilizer requirements Where to plant: Pgmary Adaptation ] Adapted to 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 K inch (6.35 min) 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.
