Project Description

The Carter Barron project fully retrofitted an 11‐acre impervious area with green infrastructure to restore natural hydrology, prevent erosion, reduce stormwater pollution, and protect and restore existing natural habitat. Throughout the design process, several new and innovative techniques were used, including: turf shelves, subsoiling, turret pre-treatment chambers, sand seepage berms, log jams, and brush mattress weirs. These techniques put habitat at the forefront of the design, while providing excellent treatment, helping this project stand out to the jurors.
