Keep the weir at least 9 inches lower than the outer edges at natural ground elevation. The weir length is variable to the size of the drainage area and peak runoff. Minimum "L" length to be 2/3 channel width or sizes as follows (whichever Is greater): L(ft)= 0 o�eak,�(efs) 2. Keep the side slopes of the check dam at 2:1 or flatter. 3. The apron length (lower side of check dam) should be approximately three times the height ®of the check dam with a minimum length of 4 feet. Stabilize outflow areas along the channel to resist erosion. A gaofextile grid may be used in lieu of rip rap provided project en ineer provided material & talcs t support alternate apron method. g p o pp n p e 4. Ensure that the maximum spacing between check dams places the toe of the upstream check dam at the same elevation as the top of the downstream check dam. 5. Use NCDOT Class B stone and line upstream side of the check dam with NCOOT #5 or #57 washed stone s S. Key the tone into the ditch banks and extend it beyond the abutments a minimum of 1.5 feet to avoid washouts from overflow around the dam. XSediment storage area (upstream and of check dam) should be sized to anticipate volume of sediment. Minimum 1 inch deep CONSTRUCTION SPECIFICATIONS 8. Place Structural stone (Class B) to the lines and dimensions shown on the plans on a filter fabric foundation. The crest width of the check dam should be a minimum of 2 feat. 9. Keep the center stone section at least 9 inches below the natural ground level where the dam abuts the channel banks. 10. Place sediment control stone (NCDOT #5 or #57) on the upstream side of the check dam that is a minimum of 1 foot thick. 11. Provide on apron that is 3 times the height of the check dam. The apron width is of least 4 feet long. Undercut stone apron so that the top of the apron is flush with the surrounding grade. 12. Extend stone at least 1.5 feet beyond the ditch banks to keep water from cutting around the ends of the check dam. 13. Excavate sediment storage area (upstream of check dam) to the dimension shown on plans. MAINTENANCE 14. Inspect check dams and channels at least weekly and after each significant (1/2 Inch or greater) rainfall event and repair immediately. Clean out sediment, straw, limbs, or other debris that could clog the channel when needed. 15. Anticipate submergence and deposition above the check dam and erosion from high flows around the edges of the check dam. Correct all damage immediately. If significant erosion occurs between check dams, additional measures can be taken such as, Installing a protective rip rap liner in that portion of the channel. (See detail 353.08) 16. Remove sediment accumulated behind the check dams as needed to prevent damage to channel vegetation, allow the channel to drain through the stone check dam and prevent large flows from carrying sediment over the check dam. Add stones to check dams as needed to maintain design height and cross section. NOTES 17. Do not use check dams with weir in Intermittent or perennial streams. 18. Contractor to verify / comply with NCDENR Erosion and Sediment Control Planning and Design Manual (Latest revision), detail 6.87.
