Regularly inspecting your stormwater BMPs (retention basins, dry ponds, vegetated swales) is essential to keeping them functional and effective. Over time, sediment buildup, erosion, and clogging can reduce their ability to manage runoff and filter pollutants. Culverts can crack or separate, causing runoff issues. Without proper maintenance, these issues can lead to system failures, costly repairs, and increased flooding risks. The best way to know if maintenance is needed is to inspect your BMP at least once a year.
