Some trees have grown within the road and may need to be removed, but most are small in diameter. Trees and brush will be windrowed off to the side. A subdrain will be installed at the base of the highwall to alleviate existing drainage issues and daylight into an adjacent natural drain where a 4' F.B. Class III ditch will be installed.
