PINE KNOLL SHORES – The town has broken ground on a natural stormwater management system designed to decrease the volume of runoff and alleviate some of the area’s flooding.
Through a partnership with the North Carolina Coastal Federation, the town is in the process of installing three swales, or long, shallow ditches along roadsides, and two bio-retention ponds in a neighborhood prone to flooding.
The installations are part of a broader set of tools known as best management practices, or BMPs, for stormwater, because of their ability to clean and move runoff.
The goal of the retrofits is to get the water off paved areas and onto the ground, where it has the chance to soak in. This decreases volume of stormwater runoff and filters out pollutants.
