DSWC PLATE. 3.13 -2 Source: Va• DSWC MUD TRAP DESIGN 1. Modified mud traps shall not have a drainage area in excess of 3 acres during any part of the construction process. 2. Drainage areas shall have a wet storage pit excavated in front of the stone weir outlet equal to the requirements for temporary sediment traps (Std. & Spec. 3.13.) (i.e. 67 cubic yards of storage per drainage acre, not to exceed 4' in depth, with side slopes not to exceed 2:1). 3. Modified traps shall not be used in areas where rock or some other hard surface prevents the full and uniform depth anchoring of the barrier. 4. An effort shall be made to locate the barrier at least 5 to 7 feet beyond the base of slopes with grades greater than 7 %. 5. Wire fence reinforcement for silt fence shall be a minimum of 14 gauge and shall have a maximum mesh spacing of 6 inches. 6. The wire shall extend a minimum 4 inches into the ground and must be fastened securely to the upslope side of the posts using heavy duty wire staples at least one inch long, lye wires or hog rings, 7. If wooden stakes are utilized for modified mud trap construction, they must have a minimum diameter of 3 inches when oak is used and 5 inches when pine is used. Wooden stakes must have a minimum length of 5 feet. 8. If steel posts (standard "U" or "T" section) are utilized for the modified mud trap construction, they must have a minimum weight of 1.33 pounds per linear foot and shall have a minimum length of 5 feet. 9. Support posts or stakes for this type of application shall be placed a Maximum 10 -feet apart (see Plate 3.05 -1) except within the wet storage area. The wet storage area shall have the posts or stakes placed a Maximum 3 -feet apart for added support. 10. Silt fence shall conform to the construction specifications for "extra strength" found in table 3.05 -13 and shall be cut from a continuous roll to avoid joints. 11. The fabric shall be entrenched a minimum 8" in depth and back filled with clean soil. The soil shall be compacted to 95% over the filter fabric. 12. The height of the silt fence shall be a minimum of 34 inches above the original ground and shall not exceed 48 inches above ground elevation. 13. The outlet for the modified mud trap shall consist of a stone section of the wire- supported silt fence located at the low point or point of concentration for storm flows. The measure shall consist of the wire- supported silt fence installed with an opening from 4 to 8 feet wide located in the low point or point of concentration for storm flows. The opening shall have a combination of course aggregate and riprap installed to provide for filtering /detention as well as outlet stability. The smaller stone shall be VDOT #3, #357 or #5 Course Aggregate (smaller stone sizes will enhance filter efficiency) and riprap shall be "Class I." Filter cloth which meets the physical requirements noted in Std. & Spec. 3.19, RIPRAP shall be placed at the stone -soil interface to act as a "Separator." The crest of the stone outlet must be at least 1.0 foot below the top of the Wire - supported silt fence to ensure that the flow will travel over the stone and not over the fence. The outlet shall be configured as noted in Plate 3.13 -2. 14. Maintenance: a. Silt fence shall be inspected immediately after each rainfall and atleast daily during prolonged rainfall. Any required repairs shall be made immediately. b. Close attention shall be paid to the repair of damaged silt fence resulting from end runs and undercutting. c. Should the fabric on a silt fence decompose or become ineffective prior to the end of the expected usable life and the barrier is still necessary, the fabric shall be replaced promptly. d. Sediment shall be removed and the trap restored to its original dimensions when the sediment has accumulated to one half of the design volume of the wet storage or eminent failure is evident. Sediment removal from the area shall be deposited in a suitable area and in such a manner that it will not erode and cause sedimentation problems. e. Stone shall be regularly checked to ensure that filtration performance is maintained. Stone choked with sediment shall be removed and cleaned or replaced. f. The structure shall be checked regularly to ensure that it is structurally sound and has not been damaged by erosion or construction equipment. The height of the stone outlet shall be checked to ensure that its center is atleast 1 foot below the top of the fence. g. Temporary structures shall be removed when they have served their useful purpose, but not before upslope area has been permanently stabilized.

Each unit shall be constructed at the locations and elevations according to the sizes shown on the approved drawings. Any modifications to the elevation or location shall be at the direction of and approved by the Engineer. B. If the Filterra® is stored before installation, the top slab must be placed on the box using the 2x4 wood provided, to prevent any contamination from the site. All internal fittings supplied (if any), must be left in place as per the delivery. C. The unit shall be placed on a compacted sub -grade with a minimum 6 -inch gravel base matching the final grade of the curb line in the area of the unit. The unit to be placed such that the unit acid top slab match the grade of the curb in the area of the unit. Compact undisturbed sub -grade materials to 95% of maximum density at +1- 2% of optimum moisture. Unsuitable material below sub -grade shall be replaced to the site engineer's approval. D. Outlet connections shall be aligned and sealed to meet the approved drawings with modifications necessary to meet site conditions and local regulations. E. Once the unit is set, the internal wooden forms and protective rush cover must be left intact. Remove only the temporary wooden stripping blocks between the box and top slab. The top lid shotild be sealed onto the box section before backfilling, using a non- shrink grout, butyl rubber or similar waterproof seal. The boards oil top of the lid and boards sealed in the unit's throat must NOT be removed. The Supplier (Americast or its authorized dealer) will remove these sections at the time of activation. Backfilling should be performed in a careful manner, bringing the appropriate fill material up in 6" lifts on all sides. Precast sections shall be set in a manner that will result in a watertight joint, In all instances, installation of Filterra' unit shall conform to ASTM specification C891 "Standard Practice for Installation of Underground Precast Utility Structures ", unless directed otherwise in contract docutnents. F. Curb and gutter construction (where present) shall ensure that the flow -line of the Filterra T unfits is at a greater elevation than the flow -line of the bypass structure or relief. (drop inlet, curb cut or similar). Failure to comply with this guideline may cause failtue and/or dartrage to the Filterra`D environunental device. G. Each Filterra' unit must receive adequate irrigation to ensure survival of the living system during periods of drier weather. This may be achieved through gutter flow or through the tree grate. 0612£1'05 www. fl] terra. coin Toll free: (666) 349 -3438 Activation fi [to rra A. Activation of the Filterre unit is performed ONLY by the Supplier. Purchaser is responsible for Filterra` inlet protection and subsequent clean out cost. This process cannot commence witil the project site is fully stabilized and cleaned (full landscaping, grass cover, final paving and street sweeping completed), negating the chance of construction materials contaminating the Filterra' system. Care shall be taken during construction not to damage the protective throat and top plates. B. Activation includes installation of plant(s) and mulch layers as necessary. Maintenance A. Each correctly installed Filterral� unit is to be maintained by the Supplier, or a Supplier approved contractor for a nnirumlun period of 1 year, The cost of this service is to be included in the price of each FilterraO unit. Extended maintenance contracts are available at extra cost upon request. B. Annual maintenance consists of a maxinmmn of (2) scheduled visits. The visits are scheduled seasonally; the spring visit aims to clean up after winter loads including salts and sands. The fall visit helps the system by removing excessive leaf litter. C. Each maintennance visit consists of the following tasks. 1. Filterra` unit inspection 2. Foreign debris, silt, mulch & trash removal 3. Filter media evaluation and recharge as necessary 4. Plant Health evaluation and pruning or replacement as necessary 5. Replacement of mulch 6. Disposal of all maintenance refuse itenns 7. Maintenance records updated and stored (reports available upon request) D. The beginning and ending date of Supplier's obligation to maintain the installed system shall be determined by the Supplier at the time the system is activated. Owners must promptly notify the Supplier of any damage to the plant(s), which constitute(s) an integral part of the bioretention technology. 06/28/05 A www.filterra.com 6" � � W = 6' -0" � f--- 6" io - -- -- ------ - - - - -- . co I I I I I I I I I I -__ - II I 1 I � � I I I I I I I I I I I I ---------- I - --- - - - -- -I lo_ .
