Vegetation Barriers Around Headwalls of Edge Drains, Final Report

The aggregate and concrete barriers cost about the same to construct. The concrete barriers are providing good performance while the aggregate barriers range from marginal to satisfactory. A few cracks have developed in some concrete barriers. The aggregate barriers after four years of service are becoming overgrown with vegetation. Cut vegetation has a tendency to stay on the headwall where on concrete barriers it tends to blow off. No maintenance charges were claimed for either type of barrier. Aggregate barriers are not recommended.
