Mountain Creek, an impaired stream located in Chattanooga, TN, was experiencing severe bank erosion at Red Bank Elementary School. If left unaddressed, the bank erosion would eventually jeopardize the stability of the school's access road and outdoor nature classroom TenneSEA (Student Environmental Alliance), a Chattanooga-based environmental organization that collaborates with communities to teach children about their connection to nature, decided to find a solution.


A collaborative team of local businesses, non-profit organizations, school and government agencies determined that the SCOURLOK™ Engineered Bank Stabilization system would be the right solution. SCOURLOK is a system designed to resist extreme hydraulic and non-hydraulic stresses to help protect and restore stream banks while promoting vegetation to improve water quality. The system is comprised of interlocking metal baskets lined with a GEOTEX® nonwoven geotextile and armored with PYRAMAT® 75 High Performance Turf Reinforcement Mat (HPTRM) to prevent erosion and promote sediment removal. Two tiers of the SCOURLOK system were installed along 105 feet of Mountain Creek for bank restoration. Additionally, ARMORMAX was used to stabilize and prevent future erosion to the slope above SCOURLOK.

Since installation, the stream bank is stabilized and performing well even after heavy rainfalls while remaining a more aesthetically pleasing vegetated solution that works as a water quality compliance BMP.
