| The Corps flood prevention and response efforts help to limit the level of environmental damage caused nationwide by floods. As part of its flood damage reduction efforts, the Corps also has instituted a program to limit erosion on coastal shores in an effort to not only protect property and infrastructure, but also valuable habitats. Read more about these efforts in the coastal protection section. Environmental considerations are an integral component of the planning process for all of the flood damage reduction projects the Corps undertakes. For example, the Corps has begun to place more emphasis on non-structural flood control solutions rather than structural ones (dams, levees, etc.) Non-structural solutions involve modifying how floodplains are used or accommodating current uses to potential flood hazards. A non-structural approach helps avoid changes to the floodplains that might have a negative effect on the environment. Floodplains are complex natural systems that provide habitat for plants, fish and wildlife, and contribute to the overall health of the environment. Significant changes to floodplains can upset this delicate balance. An excellent example of the environmental benefits of the Corps flood reduction projects is the Napa River Flood Protection Project in Napa, California. The Napa River drainage basin comprises 426 square miles. The Flood Protection Project includes floodwalls, levees, excavated bypasses, bridge relocations, and pumping stations, all of which will help to significantly reduce the potential for flood damage. The innovative design approach, though, also allowed for extensive ecosystem restoration in excavated areas.
