Flood Risk

Every year floods sweep through communities across the Unites States taking lives, destroying property, shutting down businesses, harming the environment and causing millions of dollars in damages. Nearly 94 million acres of land in the United States are at risk for flooding. It is impossible to prevent all floods but it is possible to prevent some and to limit the impact of those that do occur.

One of the primary missions of the U.S. Army Corps of Engineers is flood risk management. Through effective planning, forecasting and preparation the Corps is working to help communities prevent floods where possible and significantly reduce the loss of lives and the economic and environmental impact when they do occur. The Corps also is involved in flood emergency response efforts.

The Corps helps put in place measures designed to reduce risks from flood hazards to people and their homes and businesses. We also provide people who live and work in floodplains with the information they need to know about flood hazards and the actions that they themselves can take to reduce property damage and to prevent the loss of life caused by flooding.

Flood Risk Management reduces the risk of damage and loss of life due to flooding and coastal storms. However, risk can never be completely eliminated. Substantial flood damage still occurs and lives are still at risk from flooding. Read more…

In the United States, the responsibility for managing flood risks is shared across the Federal, state and local levels of government and the private sector. In the absence of continuous collaboration, conflicting policies, programs and interests from multiple layers of government can work at cross purposes and undermine efforts to improve flood risk management nationwide.
