Previously approved ATV hails upgraded for project use Previotts <br /> would remain open following project completion and NEPA <br /> would be decommissioned to ATV trails. decision <br />New roads 12. Light-use or low-volume (Service Level 3, 4 & 5}public Road Use <br /> roads (designed to applicable design standards based on Permit (FSM <br /> American Association of State Highway and 2733.04b <br /> Transportation Officials (AASHTO) "Guidelines for and FSM <br /> Geometric Design of Very Low-Volume Local Roads '7'730) <br /> (ADT<400).Low Volume Road Standards) and pads will ~SHTO <br /> be graveled. Surfacing access roads, including open Design <br /> channel crossings of minor tributaries should utilize Standard <br /> gravel or crushed rock on the running surface of the road <br /> to reduce ongoing erosion of the channels by vehicle <br /> traffic. <br /> 13. Although somewhat conflicting with direction regarding Water <br /> Lynx (LCAS), based on geologic instability and wet areas Conservation <br /> warrant that new project specific roads will be laid out on Practices <br /> top of ridges (or the top one-third of hillside).

Stream crossings will be minimized in number and Federal Coal <br /> engineered to protect streams from sedimentation and Lease <br /> erosion and will additionally be laid out at right angles to Stipulation <br /> flow. <br /> 15. Cross slopes will be maintained on access roads to Road Use <br /> promote removal of water from the road surface.

Ditches would be allowed to vegetate or include large WCPH (FSH <br /> rocks or stones to slow the velocity of drainage and allow 2509.25) <br /> sediment to settle out. <br /> 17. Where drainage ditches are installed to direct runoff away Project Plan, <br /> from the road, water bars or hay bale dikes would be WCPH (FSH <br /> installed perpendicular to the flow direction of the ditch 2509.25) <br /> to reduce runoff velocity and settle out sediment on <br /> steeper grades. <br />23 <br />
