DESCRIPTION
The Middle Touchet River reach is classified as a priority restoration and protection reach for salmon recovery. The reach has been impacted by river levees and straightening. As a result of river confinement and development encroachment into the floodplain, the Touchet River historically has topped its containment damaging homes and businesses in the floodplain. Conventional methods to treat these problems have included building higher and stronger levees. These methods are both very costly and detrimental to the recreational value of watersheds. An option to raising river levees is to build river levee setbacks. Levee setbacks increase the floodplain volume and reduce flood crest height, provide properly functioning floodplains where healthy riparian habitats can develop aiding in recovery of endangered steelhead. This project will provide an option to landowners for mitigating for damage caused to their property by levee failure by aiding them in conducting levee setback alternatives identified in levee setback assessments.
