There is a flood control dam about 2000 ft south of Materials and Fuels Complex (MFC). The dam is at risk of failure during a large runoff event. This project will reinforce the flood control dam with additional earthen material and a concrete headwall around the culvert inlet. The workscope consists of 1) Removing riprap from the existing slope around the culvert area. 2) Installing a concrete headwall structure around the culvert inlet. 3) Increase the slope of the dam at the culvert inlet and around the headwall to a 3:1 slope. 4) Replace riprap around headwall.
