Sprinkling The site may be sprinkled until the surface is wet. Sprinkling is especially effective for dust control on haul roads and other traffic routes. Stone used to stabilize construction roads can also be effective for dust control. Barriers -A board fence, wind fence, sediment fence, or similar barrier can control air currents and blowing soil. Place barriers perpendicular to prevailing air currents at intervals about 15 times the barrier height. Where dust is a known problem, preserve windbreak vegetation. Tillage -Deep plow large open undisturbed areas and bring clads to the surface. This is a temporary emergency measure that can be used as soon as soil blowing starts.

Use clean gravel, %- to %z-inch in diameter, placed 2 inches below the top H P of the block on a 2:1 slope or flatter and smooth it to an even grade. DOT #57 washed stone is recommended. NOT TO SCALE size of 14 inches. The entire upstream face of the rock structure should be covered with fine gravel (NCDOT #57 or #5 wash stone) a minimum of 1 foot thick to reduce the drainage rate. Side slopes Keep the side slopes of the spillway section at 2:1 or flatter. To protect the embankment, keep the sides of the spillway at least 21 inches thick. DepthThebasin should be excavated 1.5 feet below grade. Stone spillway height -The sediment storage depth should be a minimum of 2 feet and a maximum of 3.5 feet above grade. Protection from piping Place filter cloth on the foundation below the riprap to prevent piping. An alternative would be to excavate a keyway trench across the riprap foundation and up the sides to the height of the dam. Weir length and depthKeepthe spillway weir at least 4 feet long and sized to pass the peak discharge of the 10-year storm (Figure 6.60a). A maximum flow depth of six inches, a minimum freeboard of 1 foot, and maximum side slopes of 2:1 are recommended. Weir length may be selected from Table 6.60a shown for most site locations in North Carolina.

Maintenance Inspect the barrier at least weekly and after each significant (% inch or greater) rainfall and make repairs as needed. 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.

Construction 1. Clear, grub, and strip the area under the embankment of all vegetation and Specifications root mat. 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. 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. Over fill the embankment 6 inches to allow for settlement. 3. Construct the outlet section in the embankment. Protect the connection between the riprap and the soil from piping by using filter fabric or a keyway cutoff trench between the riprap structure and soil. • Place the filter fabric between the riprap and the soil. Extend the fabric across the spillway foundation and sides to the top of the dam; or • Excavate a keyway trench along the center line of the spillway foundation extending up the sides to the height of the dam. The trench should be at least 2 feet deep and 2 feet wide with 1:1 side slopes. 4. Clear the pond area below the elevation of the crest of the spillway to facilitate sediment cleanout. 5. All cut and fill slopes should be 2:1 or flatter. 6. Ensure that the stone (drainage) section of the embankment has a minimum bottom width of 3 feet and maximum side slopes of 1:1 that extend to the bottom of the spillway section. 7. Construct the minimum finished stone spillway bottom width, as shown on the plans, with 2:1 side slopes extending to the top of the over filled embankment. Keep the thickness of the sides of the spillway outlet structure at a minimum of 21 inches. The weir must be level and constructed to grade to assure design capacity. 8. Material used in the stone section should be a well -graded mixture of stone with a d5, size of 9 inches (class B erosion control stone is recommended) and a maximum stone size of 14 inches. The stone may be machine placed and the "......, smaller stones worked into the voids of the larger stones. The stone should be %hard, angular, and highly weather -resistant. oL 9. Discharge inlet water into the basin in a manner to prevent erosion. Use temporary slope drains or diversions with outlet protection to divert sediment - TEMPORARY laden water to the upper end of the pool area to improve basin trap efficiency SEDIMENT (References: Runoff Control Measures and Outlet Protection).
