Assessments of damage from storms in 1995 and 1996 to three forest road segments on the Detroit Ranger District of the Willamette National Forest are reported. Consequences to roads and road-related structures are discussed. Changes for the three road segments in the designs and materials used for road surfacing and road drainage structures including ditches and cross drains are suggested. Information is based on that developed and reported for other publications in the Water/Road Interaction Technology Series.
