Stormwater Systems We Maintain

Above-Ground Stormwater SCMs

Above-ground stormwater SCMs such as wet ponds, bioretention basins, vegetated swales, and permeable pavement systems manage stormwater runoff by slowing flow, promoting infiltration, and removing pollutants before discharge. Proper inspection, maintenance, and repair of above-ground stormwater control measures are essential to maintain hydraulic capacity, prevent erosion, and ensure long-term stormwater compliance in North Carolina.
