With respect to line location, ground disturbance is a major concern for us, and line strikes are something that we take very seriously. Over the course of time, we have in a more complete way taken ground disturbance to a new level with respect to how we implement it. I'll leave it at that for the moment.
Our compaction techniques employ things like sheep-foot compactors. We use narrow compacting equipment, rollers and tampers. Some of the lines require some fairly exquisite geometry, but they've been made for this purpose.
