Erosion Control
Effective erosion control measures shall be in place at all times during construction. Construction shall not start until all temporary control materials and devices (e.g., straw bales with sterile, weed-free straw, silt fences) are in place downslope or downstream of the work site within the riparian area. The materials shall be properly installed at all locations where the likelihood of sediment input exists. These materials shall be in place during and after construction activities for the purposes of minimizing fine sediment and sediment/water slurry input to flowing water and to detain sediment-laden water on site. If continued erosion is likely to occur after construction is complete, then appropriate erosion prevention measures shall be implemented and maintained until erosion risk has subsided.
