Beyond height, Clackamas County requires fences to preserve corner vision: nothing sight-obscuring over 30 inches within a 20-foot radius of an intersection or where a driveway meets a public road, so drivers can see.
The ZDO's dimensional standards include a corner-vision rule that applies countywide in unincorporated areas. No sight-obscuring structure or planting over 30 inches tall may sit within a 20-foot radius of the lot corner nearest the intersection of two public/county/state roads, or where a private road, driveway, or easement meets a public road. Trees in that triangle must be limbed up to give 8 feet of clearance below the lowest branches. These sight-line requirements apply on top of the district height limits and setbacks.
A fence, hedge, or wall blocking the corner-vision triangle is a ZDO violation; Code Enforcement can order it lowered or removed to restore the required sight distance.
