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. ▪ Perform preventative maintenance work to safeguard against storm damage, such as blading to ensure correct runoff, ditch and culvert cleaning, and waterbar maintenance.

Subsurface Conditions Unless the Contract Documents stipulate specific quantities and units of rock or unsuitable soils, the Contractor shall assume material below the surface of the Earth to be earth and other material that can be removed by power shovel or similar equipment.
