Completing a Drains Project
When drains project is completed there are a number of tasks you should complete.
• Replace rock washouts near culvert and channel outlets. Fill, grade, and seed or riprap eroded areas around inlets and outlets. Make sure downstream ditches and channels are fully vegetated. Fill and seed any gullies along the banks or other slopes.
• Remove all silt fencing and stakes. Grade out and seed or remove accumulated sediment or broadcast over grassed areas or dispose of off site.
• Check areas where erosion control blankets or matting was installed. Cut away and remove all loose, exposed material, especially in areas where walking or mowing will occur. Reseed all bare soil areas.
• Fill in, grade, and seed all temporary sediment traps and basins that have been removed. Double the seeding rate where runoff flows might converge or high velocity flows are expected.
• Remove temporary stream crossings and grade, seed, or re-plant vegetation removed during crossing installation.
• Culvert inlets should be stabilized, vegetated, and showing no visible gullies. Rock or soil that
has been washed away by runoff or upstream flows should be replaced. Brush or other debris that could clog inlets should be removed.
• Check ditches and channels to make sure banks and ditch bottoms are well vegetated. Reseed bare areas and replace rock that has become dislodged.
