This project focused on repairing an eroded channel in a basin, cleaning out spillways, and repairing denuded areas throughout the Basin Management Practice (BMP) area. Starting with the eroded channel, our team’s first step was to control the water flow by sandbagging the higher end of the channel. This temporary measure allowed us to work in a water-free environment. We then removed sediment accumulated at the bottom of the wash and prepared the base for clay placement.
After laying and compacting the clay, a 4-inch layer of topsoil was added where the wash had previously been. The area was then seeded, fertilized, and limed to encourage vegetation growth. To further stabilize the swale, we lined the bottom with EC-2 matting, anchoring it every 20 feet into the ground and securing it with staples. Once this process was complete, we removed the sandbags, allowing water to flow through the newly repaired channel.
The second part of the project involved cleaning out spillways and removing debris. This task required us to visit each inlet and outlet flared end section, clearing out all accumulated materials. The removed debris, including floatables and trash, was hauled offsite rather than being disposed of on the basin slopes. This step ensured the spillways were free from obstructions and capable of functioning effectively.
Lastly, we addressed the denuded areas throughout the BMP. Our approach was to first roughen the existing ground in bare areas and then apply new sifted topsoil. These areas were then seeded, fertilized, and limed to promote healthy vegetation growth. To prevent further erosion and stabilize these repaired areas, we installed EC-2 matting, an effective solution for maintaining the integrity of the newly planted areas.
Throughout the project, the focus was on effective water management and environmental restoration. Each step, from the initial water control measures to the final seeding and stabilization, was carried out with precision and care, ensuring the long-term success and functionality of the basin area.
