Wetlands When disposing of excess, soil, or other construction materials on public or private property, Contractor shall not fill in or otherwise convert wetlands.
Drainage Prevent silt bearing road surface and ditch runoff from delivering sediment to any streams or wetlands. Maintain rolling dips and drivable waterbars as needed to keep them functioning as intended. Maintain headwalls to the road shoulder level with material that will resist erosion. Maintain energy dissipaters at culvert outlets with non-erodible material or rock. Keep ditches, culverts, and other drainage structures clear of obstructions and functioning as intended. Inspect and clean culverts at least monthly, with additional inspections during storms and periods of high runoff. This shall be done even during periods of inactivity. Preventative Maintenance Perform preventative maintenance work to safeguard against storm damage, such as blading to ensure correct runoff, ditch and culvert cleaning, and waterbar maintenance.
