Everyone wants street trees, but roots can tear up sidewalks and cause pedestrians to trip. John Olson has the infrastructure solution.
Root barriers may not be sexy, but preserving sidewalks is an unquestionably noble goal.
Olson writes, "The root barriers are not only good for minimizing the future issues with the sidewalks, but they also assist in keeping the soil for the tree in a non-compacted state. Compaction around the tree can suffocate the tree if proper steps are not taken to minimize the compaction."
