Terra Technologies has successfully completed design development and Clean Water Act permitting for the Copperfield Bank Stabilization project in O’Fallon, Missouri. The Section 404/401 permit required minimization of impacts to the stream. Additionally, Terra Technologies and Cole & Associates designed the project to integrate native vegetation and biotechnical engineering as part of the stabilization measures.
The Copperfield Bank Stabilization Project will benefit more than thirty homes by preventing backyard erosion that threatens numerous private improvements. The project will take place along an unnamed tributary to Belleau Creek. Many stabilization techniques are being used, including gabion baskets for bank and toe protection, coir logs for toe stabilization, rock blankets for slope protection, a newberry riffle for grade control, a concrete energy dissipater for velocity reduction, and high tensile turf reinforcement matrixes along with erosion control blankets for slope protection. Native vegetation will be planted in all areas with high tensile turf reinforcement matrixes and erosion control blankets which will be beneficial for erosion control and downstream water quality.
