| Abstract: | The purpose of the proposed project is to restore the level of flood protection that existed prior to the 2014-2015 winter flooding in order to protect lives and property from subsequent flooding at the damage location. In the current damaged condition, the LOP for this levee is 4-year. The area protected by the Sande-Williams levee from the 28-year flood event was calculated to be approximately 346 acres. This protected area includes acreage (approx. 249 acres) that can be inundated by water flanking the upstream end of the levee. The levee in the undamaged condition provides flood risk reduction to the entire protected area by reducing flood water elevations and associated impacts to structures. Flood water flows through a portion of the protected area when the river flows exceed the 5-year flood event, however the Sande-Williams levee reduces the amount of flow, water elevations, and the associated damages in the protected area. |
