~~ s <br />Design Criteria <br />Topic <br />28 <br />29 <br />Criteria for the Proposed Action <br />Sections of temporary roads with roadway gradient in <br />excess of l2 percent or soft areas, which exhibit nrtting in <br />excess of 3 inches, shall be stabilized by placing an <br />adequate depth of 3-inch minus clean crushed rock. The <br />surface of the road shall be maintained to minimize ruts <br />and provide for sheet drainage across the roadway. <br />The USFS officer may require surfacing of temporary <br />roads where justified by conditions or traffic volumes. <br />Roads constructed within 660 feet of a riparian area will <br />be surfaced with 3-inch minus clean crushed rock. <br />30. To minimize resource impacts, road design and location <br />1. Should avoid wetlands, moist sites; avoid construction in <br />saddles and low divides; maintain frequent dense cover <br />areas next to roads; construct roads to minimum road <br />standard that will meet management objectives (without <br />large cut slopes, fills, or straight stretches); and facilitate <br />eventual closure (especially where roads enter drainage <br />headwaters areas). <br />Road Use <br />Permit (FSM <br />2733.04b <br />and FSM <br />7730) <br />Road Use <br />Permit (FSM <br />2733.04b <br />and FSM <br />7730); <br />WCPH (FSH <br />2509.25) <br />Forest Plan, <br />MCC Project <br />Plan, WCPH <br />(FSH <br />2509.25) <br />Road Use <br />Permit (FSM <br />2733.04b <br />and FSM <br />7730), <br />WCPH <br />32. Road construction, drilling, and MDW installation Federal Coal <br />activities are not allowed from December 1 to April 30 to Lease <br />protect big game winter range. Stipulation <br />Federal Coal Lease Stipulation <br />33. Special design, construction, and mitigation measures Forest Plan <br />jointly developed by a USFS Interdisciplinary Team and <br />MCC will be applied to project construction activities <br />proposed in steep slope, moderate slope, or geologic <br />hazard areas to minimize and control the potential for <br />slope de-stabilization and erosion. These measures may <br />include but will not be limited to site-specific drainage <br />measures, limitations on slope cut/fill angles, slope <br />construction measures (benching or slope reinforcement <br />such as temporary gabions or barricades), and slope <br />stabilization measures (such as geotextile or jute matting <br />or hydromulching). <br />26 <br />
