Problem | Practices Applied To | Comments |
---|---|---|
Clogging, sediment deposition | Both | Key issue for infiltration practice. Requires vigilant inspection and maintenance. |
Surface Vegetation | Both | Often important to maintain vigorous growth at the base of infiltration practices (basins). Important to restrict woody vegetation from the surface of infiltration trenches. |
Erosion of contributing land or in channels leading to practice | Both | In these practices, it is important to monitor not only the practice itself, but also upland infiltration to minimize the sediment load. |
Damage to filter fabric | Trench | Infrequent but important maintenance concern. |
Scouring at Inlet | Both | Similar issues to Ponds. Need to promote non-erosive flows that are evenly distributed |
Access Issues | Both | Similar issues to Ponds. Need access for inspection and maintenance. |
Concrete Failure | Basins, if they include a riser structure | Similar issues to ponds and wetlands. |
Problems with the Embankment | Basins | Similar issues to dry ponds. |
