Periodically inspect all culverts to prevent clogging, plugging and eventual failure. Remove any debris or sediment deposits that have the potential to cause clogging. All types of stream crossings may be subject to permitting by regulatory agencies. These crossings involve lining the stream channel with rock, brick, logs, concrete, or other such material. In many cases, a hard surface crossing may cost considerably less than a culvert crossing.
Cost depends on the availability of surfacing material.
Also, hard surface crossings are virtually maintenance free and normally do not become clogged or plugged because they maintain the natural shape of the stream channel. This can be an extremely important feature in areas with beaver populations. The material used in hard surface crossings is relatively large and stable. Consequently, these crossings usually do not fail or blow out as other structural crossings can. As long as the armoring material does not significantly impound flow or cause erosive currents, these crossings can accommodate normal streamflow while providing effective access at low risk to water quality.
