- (1) Operators shall use variable grades and alignments to avoid less suitable terrain so the road prism is the least disturbing to protected resources, avoids steep sidehill areas, wet areas, and potentially unstable areas as safe, effective vehicle use requirements allow.
- (2) Operators shall end-haul excess material from steep slopes or high landslide hazard locations where needed to prevent landslides.
- (3) Operators shall design roads no wider than necessary to accommodate the anticipated use and minimize environmental impacts to waters of the state and covered species from new road construction. The running surface width shall average not more than 32 feet for double lane roads and 20 feet for single lane roads, exclusive of ditches plus any additional width necessary for safe operations for fill widening or on curves, turnouts, and landings.
- (4) Operators shall design cut and fill slopes to minimize the risk of landslides.
- (5) Operators shall stabilize road fills as needed to prevent fill failure and subsequent damage to waters of the state using compaction, buttressing, subsurface drainage, rock facing, or other effective means.
- (6) Operators shall utilize end-haul construction and not place fill within the riparian management area of a stream or within 75 feet of a stream channel where a riparian management area is not required, excluding crossings and approaches to crossings.
