Protecting Stormwater Ponds: Erosion Solutions for Sustainable Shoreline Restoration

In the Lowcountry of South Carolina, many native soils are sandy. When neighborhoods were constructed, ponds were built to store excess water and filter it. These stormwater ponds were dug into sandy soils, which are highly erodible, creating a vulnerable foundation for the ponds. Over time, factors such as heavy rain, fluctuations in pond depth, wind and wave action, and natural settling have contributed to erosion along the pond edges.

Shoreline Restoration Group frequently encounters issues such as sloughed-off pond banks, collapsing shorelines, and severely undercut ledges caused by erosion in these sandy environments. Erosion reduces the pond’s water-holding capacity, which can increase the risk of flooding in surrounding neighborhoods. Additionally, when ponds erode, their ability to filter pollutants is diminished, further impairing their function.

Shoreline Restoration Group specializes in addressing eroding shorelines by using all-natural materials to reduce erosion. We also install native plants to stabilize pond edges and enhance the pond’s ability to filter pollutants, restoring the pond’s overall function.
