CONSIDERATIONS FOR CONSTRUCTION SCHEDULING CONSTRUCTION ACTIVITY SCHEDULE CONSIDERATION CONSTRUCTION ACCESS: Construction entrance, construction routes, equipment parking areas. First land-disturbing activity- Stabilize bare areas immediately with gravel and temporary vegetation as construction takes place. SEDIMENT TRAPS AND BARRIERS: Basin traps, sediment fences, and outlet protection. Install principal basins after construction site is accessed. Install additional traps and barriers as needed during grading. RUNOFF CONTROL: Diversions, perimeter dikes, water bars, and outlet protection. Install key practices after principal sediment traps and before land grading. Install additional runoff-control measures during grading. RUNOFF CONVEYANCE SYSTEM: Stabilize streambanks, storm drains, channels, inlet and outlet protection, and slope drains. Where necessary, stabilize streambanks as early as possible. Install principal runoff conveyance system with runoff-control measures. Install remainder of system after grading. LANDING CLEARING AND GRADING: Site preparation- cutting, filling and grading, sediment traps, barriers, diversions, drains, and surface roughening. Begin major clearing and grading AFTER principal sediment and key runoff-control measures are installed. Clear borrow and disposal areas only as needed. Install additional control measures as grading progresses. Mark trees and buffer areas for preservation. SURFACE STABILIZATION: Temporary and permanent seeding, mulching, sodding and riprap. Apply temporary or permanent stabilization measures immediately on all disturbed areas where work is delayed or complete. BUILDING CONSTRUCTION: Buildings, utilities, and paving.Install necessary additional erosion and sedimentation control practices as work takes place. LANDSCAPE AND FINAL STABILIZATION: Topsoiling, trees and shrubs, permanent seeding, mulching, sodding, and riprap. Last construction phase: Stabilize all open areas, including borrow and spoil areas. Remove and stabilize all temporary control areas. NOTE: The above are the main aspects of a typical construction sequence in general terms. A detailed Construction Sequence should be site specific based on your project and site needs. As a minimum, the construction sequence schedule should show the following: ·The erosion and sedimentation control practices to be installed, ·Principal development activities, ·What measures should be in place before other activities are begun, and ·Compatibility with the general construction schedule of the contract. Many timely construction techniques can reduce the erosion potential of a site, such as (1) shaping earthen fills daily to prevent overflows and (2) constructing temporary diversions ahead of anticipated storms. These types of activities cannot be put on the construction sequence schedule, but should be used whenever possible.

NOTES: 1.Construct and maintain all erosion and sediment control practices and measures in accordance with the approved sedimentation control plan and construction schedule. 2.Remove good topsoil from areas to be graded and filled, and preserve it for use in finishing the grading of all critical areas. 3.Scarify areas to be topsoiled to a minimum depth of 2 inches before placing topsoil. 4.Clear and grub areas to be filled by removing trees, vegetation, roots, or other objectionable material that would affect the planned stability of the fill. 5.Ensure that fill material is free of brush, rubbish, rocks, logs, stumps, building debris, and other materials inappropriate for constructing stable fills. 6.Place all fill in layers not to exceed 9 inches in thickness, and compact the layers as required to reduce erosion, slippage, settlement, or other related problems. 7.Do not incorporate frozen, soft, mucky, or highly compressible materials into fill slopes. 8.Do not place fill on a frozen foundation, due to possible subsidence and slippage. 9.Keep diversions and other water conveyance measures free of sediment during all phases of development. 10.Handle seeps or springs encountered during construction in accordance with approved methods (subsurface drain). 11.Permanently stabilize all graded areas immediately after final grading is completed on each area in the grading plan. Apply temporary stabilization measures on all graded areas when work is to be interrupted or delayed for 30 days or longer. 12.Show topsoil, stockpiles, borrow areas, and spoil areas on the plans, and make sure they are adequately protected from erosion. Include final stabilization of these areas in the plan. MAINTENANCE: 1.Periodically check all graded areas and the supporting erosion and sedimentation control practices, especially after heavy rainfalls. 2.Promptly remove all sediment from diversions and other water-disposal practices. 3.If washouts or breaks occur, repair immediately. 4.Prompt maintenance of small eroded areas before they become significant gullies is an essential part of an effective erosion and sedimentation control plan.

SEED BED PREPARATION: LIMING- Apply lime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the rate of 1-112 tons/acre on coarse-textured soils and 2-3 tons/acre on fine-textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. FERTILIZER- Base application rates on soil tests. When these are not possible, apply a 10-10-10 grade fertilizer at 700 - 1,000 lb/acre. Both fertilizer and lime should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application. SURFACE ROUGHENING- If recent tillage operations have resulted in a loose surface additional roughening may not be required, except to break up large clods. If rainfall causes the surface to become sealed or crusted, loosen it just prior to seeding by raking, harrowing, or other suitable methods for fine grading. The finished grade shall be a smooth even soil surface with a loosen uniformly fine texture. All ridges and depressions shall be removed and filled to provide the approved surface drainage. Planting is to be done immediately after finished grades are obtained and seedbed preparation is completed. Refertilize if growth is not fully adequate. Reseed, refertilize and mulch immediately following erosion or other damage. In the Piedmont and Mountains, a small-stemmed Sudangrass may be substituted at a rate of 50 lb/acre.

Wire or plastic zip ties should have a minimum 50 pound tensile strength. 5.When a wire mesh support fence is used, space posts a maximum of 8 feet apart. Supports should be driven securely into the ground a minimum of 24 inches. Wire mesh should be a minimum 14-gauge with 6 inch mesh spacing. 6.Extra strength filter fabric with 6 foot post spacing does not require a wire mesh support fence. Securely fasten the filter fabric directly to posts. Wire or plastic zip ties should have a minimum of 50 pound tensile strength. 7.Excavate the trench approximately 4 inches wide and 8 inches deep along the proposed line of the posts and upslope from the barrier. 8.Place 12 inches of fabric along the bottom and side of the trench. 9.Backfill the trench with soil placed over the filter fabric and compact. Thorough compaction of the backfill is critical to silt fence performance. 10.Do not attach filter fabric to existing trees. 11.Do not place across ditches, streams, or any other areas of concentrated flow. Maintenance: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater. Make any required repairs immediately. 2.Should the fabric of a sediment fence collapse, tear, decompose, or become ineffective, replace it promptly. 3.Remove sediment deposits as necessary to provide adequate storage volume for the next rain and reduce pressure on the fence. Take care to avoid undermining the fence during cleanouts. 4.Remove all fencing materials and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been properly stabilized.

Remove all surface soil containing high amounts of organic matter and stockpile or dispose of it properly. Haul all objectionable material to the designated disposal area. Place temporary sediment control measures below basin as needed. 2.Place the fill in lifts not to exceed 9 inches, and machine compact it. Over fill the embankment 6 inches to allow for settlement. 3.Place the barrel 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 around the pipe spillway in 4-inch layers and compact it under and around the pipe to at least the same density as the adjacent embankment. 4.Place a minimum depth of 2 feet compacted backfill over the pipe spillway before crossing with construction equipment. 5.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. 6.Assemble the skimmer following manufacturers instructions or as designed and lay on the bottom of the basin with the flexible joint at the inlet of the 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 and anchor it to the side of the basin.This will be used to pull the skimmer to the side for maintenance. 7.Install the spillway in undisturbed soil to the greatest extent possible. 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 of the dam for anchoring in a trench. The edges may be secured with 8-inch staples or pins. 8.Filter 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. 9.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. 10.Discharge water into the basin in a manner to prevent erosion. Use temporary slope drains or diversions with outlet protection to divert sediment-laden water to the upper end of the pool area to improve basin trap efficiency. 11.Stabilize the emergency spillway embankment and all other disturbed areas above the crest of the principal spillway immediately after construction. MAINTENANCE: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater. Make necessary repairs immediately. 2.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 can be excavated. Excavate the sediment from the entire basin, not just around the skimmer or within the first cell. 3.Make sure any vegetation growing in the bottom of the basin does not hold down the skimmer. 4.Repair baffles if they are damaged. Re-anchor the baffles if water is flowing underneath or around them. 5.Ensure the skimmer is not clogged with trash or debris. 6.If the skimmer arm or barrel pipe is clogged, remove orifice and clear debris with a plumber’s snake or by flushing with clean water. Be sure to replace the orifice before repositioning the skimmer. 7.Check fabric lined spillway for damage and make any required repairs with fabric that spans the full width of the spillway. Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement.

The staples anchor the porous baffles into the sides and bottom of the basin. 3.Grade the basin so that the bottom is level front to back and side to side. 4.Install the coir fiber baffles immediately upon excavation of the basins. 5.Install posts across the width of the sediment trap. 6.Steel posts should be driven to a depth of 24 inches and spaced in a maximum of 4 feet apart. The top of the fabric should be a minimum of 6 inches higher than the invert of the spillway. Tops of the baffles should be a minimum of 2 inches lower than the top of the earthen embankment. 7.Install 3 coir fiber baffles in basins at drainage outlets with a spacing of 1/4 the basin length. 2 coir fiber baffles can be installed in the basins less than 20 feet in length with a spacing of 1/3 the basin length. 8.Attach a 9-gauge high tension wire strand to the steel posts at a height of 6 inches above the spillway elevation with plastic ties or wire fasteners to prevent sagging. If the temporary sediment basin will be converted to a permanent stormwater basin of a greater depth, the baffle height should be based on the pool depth during use as a temporary sediment basin. MAINTENANCE: 1.Inspect all measures at least weekly and after each rainfall of 1.0 inch or greater and repair immediately. 2.Maintain access to baffles. If the fabric collapses, tears, decomposes, or becomes ineffective, replace immediately. 3.Remove sediment deposits when it reaches half full.

Remove sediment as necessary to provide adequate storage volume for subsequent rains. When the contributing drainage area has been adequately stabilized, remove all materials and any unstable soil, and either salvage or dispose of it properly. Bring the disturbed area to proper grade, then smooth and compact it. Appropriately stabilize all bare areas around the inlet. Silt Fence Inspect sediment fences at least once a week and after each rainfall. Make any required repairs immediately. Should the fabric of a sediment fence collapse, tear, decompose or become ineffective, replace it promptly. Remove sediment deposits as necessary to provide adequate storage volume for the next rain and to reduce pressure on the fence. Take care to avoid undermining the fence during cleanout. Remove all fencing materials and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been properly stabilized. Construction Entrance Maintain the gravel pad in a condition to prevent mud or sediment from leaving the construction site. This may require periodic topdressing with 2- inch stone. After each rainfall, inspect any structure used to trap sediment and clean it out as necessary. Immediately remove all objectionable materials spilled, washed, or tracked onto public roadways. Skimmer Basin 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 of the basin does not 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 not work, pull the skimmer over to the side of the 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 of the 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 gthe winter to prevent the skimmer from plugging with ice. Porous Baffles Inspect baffles at least once a week and after each rainfall. Make any required repairs immediately. Be sure to maintain access to the baffles. Should the fabric of a baffle collapse, tear, decompose, or become ineffective, replace it promptly. Remove sediment deposits when it reaches half full to provide adequate storage volume for the next rain and to reduce pressure on the baffles. Take care to avoid damaging the baffles during cleanout. Sediment depth should never exceed half the designed storage depth. After the contributing drainage area has been properly stabilized, remove all baffle materials and unstable sediment deposits, bring the area to grade, and stabilize it. Porous Baffle Construction Specification Gravel Inlet Protection Construction Specification Skimmer Basin Diversion Ditch Inspect temporary diversions once a week and after every rainfall. Immediately remove sediment from the flow area and repair the diversion ridge. Carefully check outlets and make timely repairs as needed. When the area protected is permanently stabilized, remove the ridge and the channel to blend with the natural ground level and appropriately stabilize it. Diversion Ditch Construction Specification Erosion Control Matting Construction Specification See installation instructions on sheet CS-36. Slope Drain Construction Specification Erosion Control Matting Inspect Rolled Erosion Control Products at least weekly and after each significant (1/2 inch or greater) rain fall event repair immediately. Good contact with the ground must be maintained, and erosion must not occur beneath the RECP. Any areas of the RECP that are damaged or not in close contact with the ground shall be repaired and stapled. If erosion occurs due to poorly controlled drainage, the problem shall be fixed and the eroded area protected. Monitor and repair the RECP as necessary until ground cover is established. Slope Drain Inspect the slope drain and supporting diversion after every rainfall, and promptly make necessary repairs. When the protected area has been permanently stabilized, temporary measures may be removed, materials disposed of properly, and all disturbed areas stabilized appropriately. EROSION CONTROL DEVICES CONSTRUCTION SPECIFICATIONS FOR Permanent Stream Crossing Inspect permanent stream crossings periodically and after major storms to check for channel blockage, erosion of abutments, channel degradation, riprap displacement, slope failure, and piping.
