Stormwater that enters inlets 4 and 5A flows through the 505 1 -yr orifice to the bioretention until the water depth in the vault reaches 1.0', then it flows through storm pipe 3-4 towards the front of the site. 500 The 10 -year water surface elevation of the bioretention facility is 0.04' over the emergency spillway, providing sheet flow. 495 Between storm inlets 2 and 3 are three 48 pipes that function as stormwater detention. They connect to the inlets via 15" pipe. Stormwater enters this detention structure from inlet 2, as 490 shown in 5/C10, and flows out through manhole 1, as shown in 2/C10. During larger storm events, stormwater passes through the overflow pipes in inlet 2 and manhole 1, as shown in 2/C10 and 5/C10. 485 480 475 470 4" P.V.C.

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. Spring Maintenance Inspection: Key Maintenance Problems • 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. 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 underdroins 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. This reduces the average concentration of fines in the media bed and promotes quicker drawdown times. 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 (ASTM C-33 concrete sand or similar approved sand mix for bioretention media). A sufficient number of wick drains of sufficient dimension should be installed to meet the design dewatering time for the facility. 0 Remove and replace some or all of the soil media. FILTER FABRIC PLACED ON PEA GRAVEL OVER UNDERDRAIN ONLY, 1-2' ON EITHER SIDE 5"o 0k_ 31 NON—WOVEN GEOTEXTILE FABRIC WITH A FLOW RATE OF > 110 GAL./MIN./SF ON SIDES ONLY Step 1. Construction of the bioretention area may only begin after the entire contributing drainage area has been stabilized with vegetation. It may be necessary to block certain curb or other inlets while the bioretention area is being constructed. The proposed site should be checked for existing utilities prior to any excavation. Step 2. The installer should meet with the engineer for a preconstruction meeting, checking the boundaries of the contributing drainage area and the actual inlet elevations to ensure they conform to original design. Step 3. Temporary E&S controls are needed during construction of the bioretention area to divert stormwater away from the bioretention area until it is completed. Special protection measures such as erosion control fabrics may be needed to protect vulnerable side slopes from erosion during the construction process. Step 4. Any pre—treatment cells should be excavated first and then sealed to trap sediments. Step 5. Excavators or backhoes should work from the sides to excavate the bioretention area to its appropriate design depth and dimensions. Excavating equipment should have scoops with adequate reach so they do not have to sit inside the footprint of the bioretention area. Contractors should use a cell construction approach in larger bioretention basins, whereby the basin is split into 500 to 1,000 sq. ft. temporary cells with a 10-15 foot earth bridge in between, so that cells can be excavated from the side. Step 6. It may be necessary to rip the bottom soils to a depth of 6 to 12 inches to promote greater infiltration. Step 7. Place geotextile fabric on the sides of the bioretention area with a 6—inch overlap on the sides. If a stone storage layer will be used, place the appropriate depth of #57 stone on the bottom, install the perforated underdrain pipe, pack #57 stone to 3 inches above the underdrain pipe, and add approximately 3 inches of choker stone/pea gravel as a filter between the underdrain and the soil media layer. If no stone storage layer is used, start with 6 inches of #57 stone on the bottom, and proceed with the layering as described above. Step 8. Deliver the soil media from an approved vendor, and store it on an adjacent impervious area or plastic sheeting. Apply the media in 12—inch lifts until the desired top elevation of the bioretention area is achieved. Wait a few days to check for settlement, and add additional media,as needed, to achieve the design elevation. Step 9. Prepare planting holes for any trees and shrubs, install the vegetation, and water accordingly. Install any temporary irrigation. Step 10. Place the surface cover in both cells (mulch, river stone or turf), depending on the design. If coir or jute matting will be used in lieu of mulch, the matting will need to be installed prior to planting (Step 9), and holes or slits will have to be cut in the matting to install the plants. Step 11. Install the plant materials as shown in the landscaping plan, and water them during weeks of no rain for the first two months. Step 12. Conduct the final construction inspection.

Sediment shall be removed by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individual lots as well as to larger land disturbing activities. 18. TEMPORARY E&S CONTROL MEASURE REMOVAL: All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after temporary measures are no longer needed, unless otherwise authorized by the local program authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sediment. 19.
