County Road 33 Culvert Extension and Drainage Channel

Roadside stabilization has a known positive impact on water quality through the reduction of sediment loss from critical stormwater infrastructure. This reduction in sediment loss shares a direct correlation with a reduction of nutrient losses from the watershed thereby resulting in improved water quality. Grimes Creek is an area characterized by steep slopes with shallow topsoil for plant establishment. The roadside drainage in this location had created a large scour pool that formed a cascade before making its way to Grimes Creek. The stabilization of this site resulted in the slowing of erosive water velocities as well as a reduction in sediment and nutrient loss from the site.
