Purpose Sediment basins are designed to provide an area for runoff to pool and settle out a portion ofthe sediment carried down gradient. Past designs used a perforated riser for dewatering, which allowed water to leave the basin from all depths. One way to improve the sediment capture rate is to have an outlet which dewaters the basin from the top of the water column where the water is cleanest. A skimmer is probably the most common method to dewater a sediment basin from the surface. The basic concept is that the skimmer does not dewater the basin as fast as runoff enters it, but instead allows the basin to fill and then slowly drain over hours or days. This process has two effects. First, the sediment in the runoff has more time to settle out prior to discharge. Second, a pool of water forms ear] in a storm event and this further increases P Y sedimentation rates in the basin. Many of the storms will produce more volume than the typical sediment basin capacity and flow rates in excess of the skimmer capability, resulting in flow over the emergency spillway. This water is also coming from the top of the water column and has thereby been "treated" to remove sediment as much as possible. (Adapted from SoilFacts: Dewatering Sediment Basins Using Surface Outlets. N. C. State University, Soil Science Department.) Conditions Where Skimmer sediment basins are needed where drainage areas are too large Practice Applies for temporary sediment traps. Do not locate the skimmer sediment basin in intermittent or perennial streams. Planning Select locations for skimmer basins during initial site evaluation. Install Considerations skimmer sediment basins before any site grading takes place within the drainage area. Select skimmer sediment basin sites to capture sediment from all areas that are not treated adequately by other sediment control measures. Always consider access for cleanout and disposal of the trapped sediment. Locations where a pond can be formed by constructing a low dam across a natural swale are generally preferred to sites that require excavation. Where practical, divert sediment -free runoff away from the basin. A skimmer is a sedimentation basin dewatering control device that withdraws water from the basin's water surface, thus removing the highest quality water for delivery to the uncontrolled environment. A skimmer is shown in Figure 6.64a. By properly sizing the skimmer's control orifice, the skimmer can be made to dewater a design hydrologic event in a prescribed period. Because the spillway is actually used relatively frequently, it should be carefully stabilized using geotextiles, or rock if necessary, that can withstand the expected flows. The spillway should be placed as far from the inlet ofthe basin as possible to maximize sedimentation before discharge. The spillway should be located in natural groundcover to the greatest extent possible Rev. 5113 6.64.1 Practice Standards and Specifications Plan View Inflow structure i Average = Area Width W L * Area of basin water surface at tap of principal spillway elevation Inflow Structure -Dewatering Allow the maximum reasonable detention period before the basin is completely dewatered (at least 48 hours). • Inflow rate Reduce the inflow velocity and divert all sediment -free runoff: Baffles s w Skimmer dewatering device E nncy pa it w I Baffles F Freeboard d Embankment The casts of usinga skimmers stem are similar, or occasional) less than Y � Y a conventional rock outlet or perforated riser. However, the basin is more efficient in removingsediment. Anotheradvanta e of the skimmer is that it g can b reused on future projects. The disad anta e of the skimmer is e roam v P 1 g that it does require frequent maintenance r' 1 in removing debris from e rrnaa7 q q �P Y g the inlet A skimmer must dewater the basin from the top of the water surface_ The rate of dewateringmust be controlled.

Remove all surface soil containing high amounts of organic matter Specifications and stockpile or dispose of it properly. Haul all objectionable material to the designated disposal area. Place temporary sediment control measures below basin as Deeded 2. Ensure that fill material for the embankment is free of roots, woody vegetation, organic matter, and other objectionable material. Place the fill in lifts not to exceed 9 inches, and machine compact it. Overfill the embankment 6 inches to allow for settlement. 3. Shape the basin to the specified dimensions. Prevent the skimming device from settlinginto the mud b excavating a shallow it under the skimmer or Y g P providing a low support under the skimmer of stone or timber. 4. Place the barrel (typically 4-inch Schedule 40 PVC pipe) on a firm, smooth foundation of impervious soil. Do not use pervious material such as sand, gravel, or crushed stone as backfill around the pipe. Place the fill material around the pipe spillway in 4-inch layers and compact it under and around the pipe to at least the satire density as the adjacent embankment. Care must be taken not to raise the pipe from the firm contact with its foundation when compacting under the pipe haunches. Place aminimumdepth of 2 feet of compacted backfill overthe pipe spillway before crossing it with construction equipment. In no case should the pipe conduit be installed by cutting a trench through the dam after the embankment is complete. 5_ Assemble the skimmer following the manufacturers instructions, or as designed. 6. Lay the assembled skimmer on the bottom of the basin with the flexible joint at the inlet ofthe barrel pipe. Attach the flexible joint to the barrel pipe and position the skimmer over the excavated pit or support. Be sure to attach a rope to the skimmer and anchor it to the side of the basin. This will be used to pull the skimmer to the side for maintenance. 7. Earthen spillwaysInstall the spillway in undisturbed soil to the greatest extent possible. The achievement of planned elevations, grade, design width, and entrance and exit channel slopes are critical to the successful operation of the spillway. The spillway should be lined with laminated plastic or impermeable geotextile fabric. The fabric must be wide and long enough to cover the bottom and sides and extend onto the top ofthe dam for anchoring in a trench. The edges may be secured with 8-inch staples or pins. The fabric must be long enough to extend down the slope and exit onto stable ground. The width of the fabric must be one piece, not joined or spliced; otherwise water can get under the fabric. I£tbe length of the fabric is insufficient for the entire length of the spillway, multiple sections, spanning the complete width, may be used. The upper section(s) should overlap the lower section(s) so that water cannot flow under the fabric. Secure the upper edge and sides of the fabric in a trench with staples or pins. (Adapted from "A Manual for Designing, Installing and Maintaining Skimmer Sediment Basins." February, 1999, L W. Faircloth & Son.). 8.

It allows longer settling time for suspended solids remaining in the basin after a storm event, while dewatering the basin in less time than the average interval between rainfall events. Design criteria for permanent stormwater detention basins in the Division of Water Quality Stormwater BMP Manual require 2-5 days for dewatering. Procedure First determine the desired dewatering time in days (td) and the volume M of water to be released in that time period. Dividing the volume in cubic feet by the dewatering time in days gives a flow rate Qd in cubic feet per day. Qd= V ltd (ft'/day) Next determine the head on the skimmer orifice.

Divert surface water away from bare areas. Complete the embankment before the area is cleared. Stabilize the emergency spillway embankment and all other disturbed areas above the crest of the principal spillway immediately after construction (References: Surface Stabilization), 10. Install porous baffles as specified in Practice 6.65, Porous Baffles. 11. After all the sediment -producing areas have been permanently stabilized, remove the structure and all the unstable sediment. Smooth the area to blend with the adjoining areas and stabilize properly (References: Surface Stabilization). Maintenance Inspect skimmer sediment basins at least weekly and after each significant (one-half inch or greater) rainfall event and repair immediately. Remove sediment and restore the basin to its original dimensions when sediment accumulates to one-half the height of the first baffle. Pull the skimmer to one side so that the sediment underneath it can be excavated. Excavate the sediment from the entire basin, not just around the skimmer or the first cell. Make sure vegetation growing in the bottom ofthe basin does Dot hold down the skimmer. Repair the baffles if they are damaged. Re -anchor the baffles if water is flowing underneath or around them. If the skimmer is clogged with trash and there is water in the basin, usually jerking on the rope will make the skimmer bob up and down and dislodge the debris and restore flow. If this does notwork, pull the skimmer over to the side ofthe basin and remove the debris. Also check the orifice inside the skimmer to see if it is clogged; if so remove the debris. If the skimmer arm or barrel pipe is clogged, the orifice can be removed and the obstruction cleared with a plumber's snake or by flushing with water. Be sure and replace the orifice before repositioning the skimmer. Check the fabric lined spillway for damage and make any required repairs with fabric that spans the full width ofthe spillway. Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement. Make all necessary repairs immediately. Remove all trash and other debris from the skimmer and pool areas. Freezing weather can result in ice forming in the basin. Some special precautions should be taken in the winter to prevent the skimmer from plugging with ice. Rev. 5113 6.64.9 SKIMMER SEDIMENT BASIN DESIGN CRITERIA DRAINAGE AREA < 10 AC. (ACRES) MIN.

Basin dewateringThe basin should be provided with a surface outlet. A floatingskimmer should be attached to a Schedule 40 PVC barrel pipe of the PP same diameter as the skimmer arm. The orifice in the skimmer will control the rate of dewatering The skimmer should be sized to dewaterinthe basin 2-5 days). Outlet ProtectionDischargevelocities must be within allowable limits for the receiving stream (References: Outlet Protection). Basin spillway -Construct the entire flow area ofthe spillway in undisturbed soil if possible. Make the cross section trapezoidal with side slopes of 3:1 or flatter. • Capacity -The minimum design capacity ofthe spillway must be the peak rate of runoff from the 10-year storm. Maximum depth of flow during the Y P g peak runoff should be 6 inches. In no case should the freeboard of the spillway be less than 1 foot above the design depth of flow. Velocity Ensure that the velocity of flow discharged from the basin is nonerosive for the existing conditions. When velocities exceed that allowable for the receivingareas provide outlet protection (References: , P P Outlet Protection). Embankment Ensure that embankments for skimmer sediment basins do not exceed 5 feet in height (measured at the center line from the original ground surface to the top of the embankment). Keep the crest ofthe spillway outlet a minimum of 1.5 feet below the top of the embankment. Additional freeboard may be added to the embankment heightwhich allows flow through a designated bypass location. Construct embankments with a minimum top width of 5 feet and side slopes of 2:1 or flatter. Machine compact the embankments. Exeava ion -Where sod ment pools are formed or enlarged by excavation, keep side slopes at 2:1 or flatter for safety. Erosion protection Stabilize all areas disturbed by construction (except the lower half of the sediment pool) by suitable means immediately after completing the basin (References: Surface Stabilization), Trap efficiency Improve sediment basin trapping efficiency by employing the following considerations in the basin design: • Surface area In the designof the settling pond, allow the largest surface area possible. • Length -Maximize the length -to -width ratio of the basin to prevent short circuiting, and ensure use of the entire design settling area. • Baffles -Provide a minimum of three porous baffles to evenly distribute flow across the basin and reduce turbulence. • Inlets -Area between the sediment inlets and the basin should be stabilized by geotextile material, with or without rocks (Figure 6.64c shows the area with rocks). The inlet to basin should be located the greatest distance possible fromthe principal spillway. 6.64.6 Rev.5/13 SKIMMER DEWATERING DEVICE --Ni-BAFFLES 1' FREEBOA 6" MAX.

Place temporary sediment control measures below basin as Deeded 2. Ensure that fill material for the embankment is free of roots, woody vegetation, organic matter, and other objectionable material. Place the fill in lifts not to exceed 9 inches, and machine compact it. Overfill the embankment 6 inches to allow for settlement. 3. Shape the basin to the specified dimensions. Prevent the skimming device from settlinginto the mud b excavating a shallow it under the skimmer or Y g P providing a low support under the skimmer of stone or timber. 4. Place the barrel (typically 4-inch Schedule 40 PVC pipe) on a firm, smooth foundation of impervious soil. Do not use pervious material such as sand, gravel, or crushed stone as backfill around the pipe. Place the fill material around the pipe spillway in 4-inch layers and compact it under and around the pipe to at least the satire density as the adjacent embankment. Care must be taken not to raise the pipe from the firm contact with its foundation when compacting under the pipe haunches. Place aminimumdepth of 2 feet of compacted backfill overthe pipe spillway before crossing it with construction equipment. In no case should the pipe conduit be installed by cutting a trench through the dam after the embankment is complete. 5_ Assemble the skimmer following the manufacturers instructions, or as designed. 6. Lay the assembled skimmer on the bottom of the basin with the flexible joint at the inlet ofthe barrel pipe. Attach the flexible joint to the barrel pipe and position the skimmer over the excavated pit or support. Be sure to attach a rope to the skimmer and anchor it to the side of the basin. This will be used to pull the skimmer to the side for maintenance. 7. Earthen spillwaysInstall the spillway in undisturbed soil to the greatest extent possible. The achievement of planned elevations, grade, design width, and entrance and exit channel slopes are critical to the successful operation of the spillway. The spillway should be lined with laminated plastic or impermeable geotextile fabric. The fabric must be wide and long enough to cover the bottom and sides and extend onto the top ofthe dam for anchoring in a trench. The edges may be secured with 8-inch staples or pins. The fabric must be long enough to extend down the slope and exit onto stable ground. The width of the fabric must be one piece, not joined or spliced; otherwise water can get under the fabric. I£tbe length of the fabric is insufficient for the entire length of the spillway, multiple sections, spanning the complete width, may be used. The upper section(s) should overlap the lower section(s) so that water cannot flow under the fabric. Secure the upper edge and sides of the fabric in a trench with staples or pins.

Basin dewateringThe basin should be provided with a surface outlet. A floatingskimmer should be attached to a Schedule 40 PVC barrel pipe of the PP same diameter as the skimmer arm. The orifice in the skimmer will control the rate of dewatering The skimmer should be sized to dewaterinthe basin 2-5 days). Outlet ProtectionDischargevelocities must be within allowable limits for the receiving stream (References: Outlet Protection). Basin spillway -Construct the entire flow area ofthe spillway in undisturbed soil if possible. Make the cross section trapezoidal with side slopes of 3:1 or flatter. • Capacity -The minimum design capacity ofthe spillway must be the peak rate of runoff from the 10-year storm. Maximum depth of flow during the Y P g peak runoff should be 6 inches. In no case should the freeboard of the spillway be less than 1 foot above the design depth of flow. Velocity Ensure that the velocity of flow discharged from the basin is nonerosive for the existing conditions. When velocities exceed that allowable for the receivingareas provide outlet protection (References: , P P Outlet Protection). Embankment Ensure that embankments for skimmer sediment basins do not exceed 5 feet in height (measured at the center line from the original ground surface to the top of the embankment). Keep the crest ofthe spillway outlet a minimum of 1.5 feet below the top of the embankment. Additional freeboard may be added to the embankment heightwhich allows flow through a designated bypass location. Construct embankments with a minimum top width of 5 feet and side slopes of 2:1 or flatter. Machine compact the embankments. Exeava ion -Where sod ment pools are formed or enlarged by excavation, keep side slopes at 2:1 or flatter for safety. Erosion protection Stabilize all areas disturbed by construction (except the lower half of the sediment pool) by suitable means immediately after completing the basin (References: Surface Stabilization), Trap efficiency Improve sediment basin trapping efficiency by employing the following considerations in the basin design: • Surface area In the designof the settling pond, allow the largest surface area possible. • Length -Maximize the length -to -width ratio of the basin to prevent short circuiting, and ensure use of the entire design settling area. • Baffles -Provide a minimum of three porous baffles to evenly distribute flow across the basin and reduce turbulence. • Inlets -Area between the sediment inlets and the basin should be stabilized by geotextile material, with or without rocks (Figure 6.64c shows the area with rocks). The inlet to basin should be located the greatest distance possible fromthe principal spillway. 6.64.6 Rev.5/13 SKIMMER DEWATERING DEVICE --Ni-BAFFLES 1' FREEBOA 6" MAX.

Three days isprobahly the optimal length �oftime fortem or asy sediment controls. It allows longer settling time for suspended solids remaining in the basin after a storm event, while dewatering the basin in less time than the average interval between rainfall events. Design criteria for permanent stormwater detention basins in the Division of Water Quality Stormwater BMP Manual require 2-5 days for dewatering. Procedure First determine the desired dewatering time in days (td) and the volume M of water to be released in that time period. Dividing the volume in cubic feet by the dewatering time in days gives a flow rate Qd in cubic feet per day. Qd= V ltd (ft'/day) Next determine the head on the skimmer orifice. Table 6.64a has the values for various sizes of the Faircloth skimmer. Table 6.64a Head on orifice of various skimmer sizes Skimmer Size (in.)

Qd = V / td (ft3/day) - 20,000 ft3 / 3 days - 6670 (W/day). 2, Try a 4 inch skimmer, with H - 0,333 ft. (Table 6.64a) 3. D = Qd /(2V 310 * V'11) (in.)= 6676 ft3/day /(2310 * 0V 333 f.) (in.) = 2.24 inches (Use 2 %inches) Rev. 5113 6.64.3 6.64.4 Practice Standards and Specifications 9. Erosion comrol�--Construct the structure so that the disturbed area is minimized. Divert surface water away from bare areas. Complete the embankment before the area is cleared. Stabilize the emergency spillway embankment and all other disturbed areas above the crest of the principal spillway immediately after construction (References: Surface Stabilization), 10. Install porous baffles as specified in Practice 6.65, Porous Baffles. 11. After all the sediment -producing areas have been permanently stabilized, remove the structure and all the unstable sediment. Smooth the area to blend with the adjoining areas and stabilize properly (References: Surface Stabilization). Maintenance Inspect skimmer sediment basins at least weekly and after each significant (one-half inch or greater) rainfall event and repair immediately. Remove sediment and restore the basin to its original dimensions when sediment accumulates to one-half the height of the first baffle. Pull the skimmer to one side so that the sediment underneath it can be excavated. Excavate the sediment from the entire basin, not just around the skimmer or the first cell. Make sure vegetation growing in the bottom ofthe basin does Dot hold down the skimmer. Repair the baffles if they are damaged. Re -anchor the baffles if water is flowing underneath or around them. If the skimmer is clogged with trash and there is water in the basin, usually jerking on the rope will make the skimmer bob up and down and dislodge the debris and restore flow. If this does notwork, pull the skimmer over to the side ofthe basin and remove the debris. Also check the orifice inside the skimmer to see if it is clogged; if so remove the debris. If the skimmer arm or barrel pipe is clogged, the orifice can be removed and the obstruction cleared with a plumber's snake or by flushing with water. Be sure and replace the orifice before repositioning the skimmer. Check the fabric lined spillway for damage and make any required repairs with fabric that spans the full width ofthe spillway. Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement. Make all necessary repairs immediately. Remove all trash and other debris from the skimmer and pool areas. Freezing weather can result in ice forming in the basin. Some special precautions should be taken in the winter to prevent the skimmer from plugging with ice. Rev. 5113 6.64.9 SKIMMER SEDIMENT BASIN DESIGN CRITERIA DRAINAGE AREA < 10 AC. (ACRES) MIN.

Provide access for sediment removal throughout the life of the project; for Erosion and Sediment Control/Stormwater Certification for NC Interfere minimally with construction activities. DOT Projects Level IIIA and IIIB, N.C. State University, Department of Biological and Agricultural Engineering, 2007. Basin shape -Ensure that the flow length to basin width ratio is at least 2:1 to improve trapping efficiency. Length is measured at the elevation of the principal spillway. Storage volume Ensure that the sediment storage volume ofthe basin, as measured to the elevation of the crest of the spillway, it least principal s a s 1,800 cubic feet per acre for the disturbed area draining into the basin (1,800 cubic feet is equivalent to balf an inch of sediment per acre of basin disturbed area). Remove sediment from the basin when approximately one-half ofthe storage volume has been filled. Spillway capacity The spillway system must carry the peak runoff from the 10-year storm with a minimum 1 foot of freeboard in the spillway. Base runoff computations on the disturbed soil cover conditions expected during the effective life of the structure. Sediment cleanout elevationDetermine the elevation at which the invert of the basin would be half -full. This elevation should also be marked in the field with a permanent stake set at this ground elevation (not the top ofthe stake). Rev, 5113 Rev. 5/13 6.64.5 Reference Jarrett, A. R.

Basin dewateringThe basin should be provided with a surface outlet. A floatingskimmer should be attached to a Schedule 40 PVC barrel pipe of the PP same diameter as the skimmer arm. The orifice in the skimmer will control the rate of dewatering The skimmer should be sized to dewaterinthe basin 2-5 days). Outlet ProtectionDischargevelocities must be within allowable limits for the receiving stream (References: Outlet Protection). Basin spillway -Construct the entire flow area ofthe spillway in undisturbed soil if possible. Make the cross section trapezoidal with side slopes of 3:1 or flatter. • Capacity -The minimum design capacity ofthe spillway must be the peak rate of runoff from the 10-year storm. Maximum depth of flow during the Y P g peak runoff should be 6 inches. In no case should the freeboard of the spillway be less than 1 foot above the design depth of flow. Velocity Ensure that the velocity of flow discharged from the basin is nonerosive for the existing conditions. When velocities exceed that allowable for the receivingareas provide outlet protection (References: , P P Outlet Protection). Embankment Ensure that embankments for skimmer sediment basins do not exceed 5 feet in height (measured at the center line from the original ground surface to the top of the embankment). Keep the crest ofthe spillway outlet a minimum of 1.5 feet below the top of the embankment. Additional freeboard may be added to the embankment heightwhich allows flow through a designated bypass location. Construct embankments with a minimum top width of 5 feet and side slopes of 2:1 or flatter. Machine compact the embankments. Exeava ion -Where sod ment pools are formed or enlarged by excavation, keep side slopes at 2:1 or flatter for safety. Erosion protection Stabilize all areas disturbed by construction (except the lower half of the sediment pool) by suitable means immediately after completing the basin (References: Surface Stabilization), Trap efficiency Improve sediment basin trapping efficiency by employing the following considerations in the basin design: • Surface area In the designof the settling pond, allow the largest surface area possible. • Length -Maximize the length -to -width ratio of the basin to prevent short circuiting, and ensure use of the entire design settling area. • Baffles -Provide a minimum of three porous baffles to evenly distribute flow across the basin and reduce turbulence. • Inlets -Area between the sediment inlets and the basin should be stabilized by geotextile material, with or without rocks (Figure 6.64c shows the area with rocks).

Purpose To retain sediment from small disturbed areas by reducing the velocity of sheet flows to allow sediment deposition. Conditions Where Below small -disturbed areas that are less then''V, acre per 100 feet of fence. Practice Applies Where runoff can be stored behind the sediment fence without damaging the fence or the submerged area behind the fence. Do not install sediment fences across streams, ditches, or waterways, or other areas of concentrated flow. Sediment fence should be placed along topographic elevation contours, where it can intercept stormwater runoff that is in dispersed sheet flow. Sediment fence should not be used alone below graded slopes greater than 10 feet in height. Planning A sediment fence is a system to retain sediment on the construction site. The Considerations fence retains sediment primarily by retarding flow and promoting deposition. In operation, generally the fence becomes clogged with fine particles, which reduce the flow rate. This causes a pond to develop behind the fence. The designer should anticipate ponding and provide sufficient storage areas and overflow outlets to prevent flows from overtopping the fence. Since sediment fences are not designed to withstand high water levels, locate them so that only shallow pools can form. Tie the ends of a sediment fence into higher ground to prevent flow around the end of the fence before the pool reaches design level. Curling each end of the fence uphill in a "J" pattern may be appropriate to prevent end flow. Provide stabilized outlets to protect the fence system and release storm flows that exceed the design storm. Deposition occurs as the storage pool forms behind the fence. The designer can direct flows to specified deposition areas through appropriate positioning of the fence or by providing an excavated area behind the fence. Plan deposition areas at accessible points to promote routine cleanout and maintenance. Show deposition areas in the erosion and sedimentation control plan. A sediment fence acts as a diversion if placed slightly off the contour. Amaximum slope oft percent is recommended. This technique may be used to control shallow, uniform flows from small disturbed areas and to deliver sediment -laden water to deposition areas. The anchoring of the toe of the fence should be reinforced with 12 inches of NC DOT 95 or #57 washed stone when flow will ran parallel to the toe of the fence. Sediment fences serve no function along ridges or near drainage divides where there is little movement of water. Confining or diverting runoff unnecessarily with a sediment fence may create erosion and sedimentation problems that would not otherwise occur. Rev. 5/13 6.62.1 Straw barriers have only a 0-20%trapping efficiency and are inadequate. Straw bales may notbeused inplace ofsediment fence. Prefabricated sediment fence with the fabric already stapled to thin wooden posts does not meet minimum standards specified later in this section. Anchoring of sedimentfence is critical. The toe of the fabric mustbe anchored in a trench backfilled with compacted earth. Mechanical compaction must be provided in order for the fence to effectively pond runoff. Design Criteria Ensure that drainage area is no greater than '/4 acre per 100 feet of fence. This is the maximum drainage area when the sloe is less than 2 percent. Where g P all runoff is to be stored behind [tie fence, ensure that the maximum slope length behind a sediment fence does not exceed the specifications shown in Table 6.62a. The shorter slope length allowed for steeper slopes will greatly reduce the maximum drainage area. For example, a 10-20 % slope may have a maximum slope length of 25 feet, For a 100-foot length of sediment fence, the drainage area would be 25ftX 10041= 2500sq.ft, or 0.06 acres. Table 6.62a Maximum Slope Slope Length (ft) Maximum Area (ft2) Slope Length and Slope for <2% 100 10,000 which Sediment Fence is 2 to 5% 75 7,500 Applicable 5 to 10% 50 5,000 10 to 20% 25 2,500 >20% 15 1,500 Make the fence stable for the 10-year peak storm runoff. Ensure that the depth of impounded water does not exceed 1.5 feet at any point along the fence. If non -erosive outlets are provided, slope length may be increased beyond that shown in Table 6.62a, but runoff from the area should be determined and bypass capacity and erosion potential along the fence must be checked. The velocity of the flow at the outlet or along the fence should be in keeping with Table 8.05d, Appendix 8.05. Provide a riprap splash pad or other outlet protection device for any point where flow may overtop the sediment fence, such as natural depressions or swales. Ensure that the maximumheight of the fence at a protected, reinforced outlet does not exceed 2 feet and that support post spacing does not exceed 4 feet. The design life of a synthetic sediment fence should be 6 months. Construction MATERIALS Specifications 1. Use a synthetic filter fabric of at least 95% by weight of polyolefins or polyester, which is certified by the manufacturer or supplier as conforming to the requirements in ASTM D 6461, which is shown in part in Table 6,62b. Synthetic filter fabric should contain ultraviolet ray inhibitors and stabilizers to provide a minimum of 6 months of expected usable construction life at a temperature range of 0 to 120' F. 6.62.2 Table 6.1 Da Temporary Seeding Recommendationsfor Late Winter and Early Spring Table 6.10b Temporary Seeding Recommendations for Summer Seeding mixture Species Rate (Iblacm) Rye (grain) 120 Annual lespedeza(Kobe in Piedmont and Coastal Plain, Korean in Mountains) 50 broil annual lespedeza when duration of temporary cover is not to extend beyond Ju ne.

Install posts 4 feet apart in critical areas and 6 feet apart on standard applications. 3. Install posts 2 feet deep on the downstream side of the silt fence, and as close as possible to the fabric, enabling posts to support the fabric from upstream water pressure. 4. Install posts with the nipples facing away from the silt fabric. 5. Attach the fabric to each post with three ties, all spaced within the top 8 inches of the fabric. Attach each tie diagonally 45 degrees through the fabric, with each puncture at least 1 inch vertically apart. Also, each tie should be positioned to hang on'apost nipple when tightened to prevent sagging. 6. Wrap approximately 6 inches of fabric around the end posts and secure with 3'ties. 7. No more than 24 inches of a 36 inch fabric is allowed above ground level. 8. The installation should be checked and corrected for any deviations before compaction. 9. Compaction is vitally important for effective results. Compact the soil immediately next to the silt fence fabric with the front wheel of the tractor, skid steer, or roller exerting at least 60 pounds per square inch. Compact the upstream side first, and then each side twice for a total of 4 trips. Rev. 5/13 NOTES: 1.
