Are the culvert structures properly installed and maintained? 0 B 1 <br /> Ditch Infrastructure <br /> 10). Are there settling basins or sumps to trap sediment at field ditch 0 B2 <br /> connections to laterals and other main canals prior to discharge? <br /> 11). Are these basins maintained at an appropriate frequency? B2 <br /> 12). Are ditches and canals constructed with proper side J -� B3 <br /> bank stabilization methods; i.e. sloping or shoring? <br /> Ditch Management. <br /> 13). Is vegetative cover maintained near canal or ditch banks? ❑ ❑ B4, B5 <br /> 14). Are there vegetative buffer strips maintained near environmentally _ -7 B4 <br /> sensitive lands? <br /> 15). Are measures taken to prevent side-bank erosion due to the flow u 0 B8 <br /> of water directly down the sides of the banks (i.e. berms)? <br /> 16). Are riprap, concrete headwalls, sandbags, or wingwalls 0 0 B9 <br /> used to protect canal banks from erosion? <br /> Bed/Furroiv Manage►nent. <br /> 17). Are water furrows properly shaped and grassed to prevent erosion, 0 0 B10, A1-4 <br /> rutting, and other problems that may result in excess sediment <br /> transport off-site? <br /> 18). Is a narrow herbicide band maintained with a width appropriate 0 1:1 B11 <br /> for the size of the trees? <br /> 19). Are vegetated water furrows, drain tiles, and settling basins used 0 0 B10-14 <br /> to insure minimum movement of sediment to off-site water bodies? <br /> Construction Activities: <br /> 20). Are measures taken to prevent erosion (sediment loss) during 0 0 B 10, 15 <br /> earth-working activities (i. e., hay bales or ribbon turbidity barriers)? <br /> 3 <br />
