The goal of the county project is to make the mountainside bad at transporting dirt and soot. Because sediment does not dissolve in water, Tressler said, it adds to the overall volume of rain runoff, which adds to the force of floodwater. “If we can minimize the depth of water, then it doesn't have the energy to carry the sediment. That’s a big part of this up here, is getting the sediment to fall out,” Tressler said. “Sometimes we go years without having a devastating rain event that will produce a flood event,” Tressler said.
