Or. Admin. R. 629-625-0310 - Road Prism
(1) Operators shall
use variable grades and alignments to avoid less suitable terrain so that 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.
(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.
