ditches means a man-made channel or adapted watercourse on in-bye land, which has a bed width of not less than 0.3 metres and which generally carries water away from surrounding land or field drainage systems throughout the year;
ditches. As required to minimize water quality impacts. The road must be graded and crowned to drain. Standing water may not be allowed to pool on the road. Culverts: Culverts must be placed on the natural slopes where necessary to prevent pooling of water caused by the roadbed. Culverts must extend beyond the base of the road at least 36" on both sides of the road. Winter Ice Roads Winter roads are roads that can normally support regular logging vehicle traffic only during winter months and that have a load bearing capacity derived from a combination of frost, snow, and/or ice (11 AAC 95.900(90)). Construction techniques for winter access routes depend on the range of terrain encountered, and may include clearing vegetation and ground cover needed to provide a level running surface. Road surfaces may be composed of frozen mineral soil, packed snow, ice, or surface organics (11 AAC 95.290(f) & (g)). Some segments of winter roads may cross terrain that requires construction to all season standards. Ballast for winter construction will predominately be snow, ice and frozen organics. Where ballast is required, it must be obtained from an approved borrow pit. Unless otherwise approved in writing and staked on the ground by the STATE, road fill placed by the PURCHASER must not cover, encroach on, or alter permanent or intermittent water channels. Road Width: Roads shall be 14 feet. Surfacing Width: 12 feet running surface. Use: Light short-term. Chiefly timber harvest use. No expected future extension. Surfacing: The minimum necessary to complete timber harvest operations, normally a seasonal road. Minimum requirement of 8 inches of snow and 6 inches of frost to maintain a minimum of three inches of compacted ice and snow. This standard allows for variations in winter snow conditions. Deep snow may prevent ground freezing but provide for adequate ground protection. If the ground is not frozen to a depth of at least 6 inches, additional snow depth is required. Turnouts: Must be constructed large enough for opposing truck and utility vehicles to safely get out of log truck traffic without undo maneuvering at the typical traffic speed. Turnouts are to be constructed as needed for safe passage of logging trucks and at the end of the spur.
