Flood Risk Mgmt: Economic Impact

Some of the most valuable real estate in the nation is located in areas that have a high risk of flooding. For instance, many industrial facilities are built near rivers and harbors for easy access to waterborne transportation. Likewise, coastal communities are highly desirable as residential locations and tourist destinations and offer many recreational activities. In both cases, though, there also is vulnerability to coastal storm and flood damage.

Reduction Benefits to Cost

USACE flood risk management efforts reduce the risk of flood damage to these facilities and homes, as well as to vital infrastructure such as energy grids and transportation networks. USACE flood damage reduction projects, including levees and dikes, have prevented more than $1 trillion in river and coastal flood damage, most of that within the last 35 years. Between 2008 and 2017, USACE projects prevented an estimated $87.3 billion in average annual damages. For every dollar invested in USACE flood risk management projects, approximately $9.96 in potential damages have been saved.

Typically, USACE flood risk management projects produce economic benefits as they are usually turned over to states, local communities or the private sector for ongoing operation and maintenance, creating jobs and revenue for communities.

USACE's quick emergency response to floods helps the economy by preventing or reducing damage to businesses. USACE's ability to rapidly restore utilities, clear roads and rivers, and reinstate other vital services allows companies to get back to business quickly, reducing flood related revenue losses.
