Design Criteria <br />Topic <br />Design Criteria for the Proposed Action <br />- <br />7. For roadway section with 6 inches OR LESS of new structural <br />surfacing section or existing surfacing sections with any <br />aggregate segregation or contamination by intruding fine <br />materials, no rutting, pumping or plastic deformation of the <br />roadway surface will be allowed. Rutting, plastic deformation, or <br />pumping of the surface will result in the proponent's operations, <br />on that road, ceasing immediately and remaining shutdown until <br />repairs and improvements are made to prevent additional damage <br />to the structural section. For surfacing sections with GREATER <br />THAN 6 inches of new structural surfacing section any rutting, <br />pumping or plastic deformation in excess of structural section <br />thickness (T) divided by 3 (T /3) will not be allowed and will <br />result in proponent's operations, on that road, ceasing immediately <br />and remaining shutdown until repairs and improvements are made <br />to prevent additional rutting. This T/3 limitation applies to any <br />forest road utilized by the proponent, even if it is not part of the <br />project area or transportation plan. Once shutdown, operations <br />will not resume until approved repairs or improvements are made <br />to resolve the problem. These limitations apply to any NFSR even <br />if it is not included in the project area or transportation plan. <br />Road Use <br />Permit (FSM <br />2733.04b and <br />FSM 7730) , <br />BMP, GMUG <br />Forest <br />Standard <br />New roads <br />8. Light -use or low- volume (Service Level 3, 4 & 5) public roads <br />(designed to applicable design standards based on American <br />Association of State Highway and Transportation Officials <br />(AASHTO) "Guidelines for Geometric Design of Very Low- <br />Volume Local Roads (ADT <400) Low Volume Road Standards) <br />and pads will be graveled. Surfacing access roads, including open <br />channel crossings of minor tributaries should utilize gravel or <br />crushed rock on the running surface of the road to reduce ongoing <br />erosion of the channels by vehicle traffic. <br />9. Cross slopes will be maintained on access roads to promote <br />removal of water from the road surface. Surface drainage <br />structures shall be constructed at appropriate intervals to divert <br />water from roadway surface Relief ditches at regular <br />intervals to direct drainage off of the road grade and into <br />vegetated areas. <br />10. Ditches would be allowed to vegetate or include large rocks or <br />stones to slow the velocity of drainage and allow sediment to <br />settle out. <br />11. Where drainage ditches are installed to direct runoff away from <br />the road, water bars or hay bale dikes would be installed <br />perpendicular to the flow direction of the ditch to reduce runoff <br />velocity and settle out sediment on steeper grades. <br />12. Road construction plans would identify specific locations of <br />drainage features and BMPs for approval by the FS <br />Road Use <br />Permit (FSM <br />2733.04b and <br />FSM 7730) , <br />AASH TO <br />Design <br />Standard <br />Road Use <br />Permit(FSM <br />2733.04b and <br />FSM 7730) ,, <br />WCPH(FSH <br />2509.25) <br />WCPH (FSH <br />2509.25) <br />Project Plan, <br />WCPH (FSH <br />2509.25) <br />Road Use <br />Permit (FSM <br />2733.04b and <br />
