• <br />• <br />• <br />• <br />1 <br />III SEDIMENT: Yes No BMPs <br />1 <br />Drainage Structures: _ <br />8). Are culverts with functional riser/sinker boards installed _ B1 <br />on appropriate lateral and side ditch connections? <br />9). Are the culvert structures properly installed and maintained? _ B1 <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? 0 0 B2 <br />12). Are ditches and canals constructed with proper side 0 0 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 0 0 B4 <br />sensitive lands? <br />15) Are measures taken to prevent side -bank erosion due to the flow 0 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/Furrow Management <br />17). Are water furrows properly shaped and grassed to prevent erosion, D 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 0 B11 <br />for the size of the trees? <br />19). Are vegetated water furrows, dram tiles, and settling basins used 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 1J B10, 15 <br />earth -working activities (i. e., hay bales or ribbon turbidity barriers)? <br />3 <br />
