It is a common misperception that USACE manages all levees in the nation. In reality, the levees included in the USACE Levee Safety Program represent only about 10 percent of the nation’s levees (as estimated by the National Committee on Levee Safety). However, more than 10 million people live or work behind USACE program levees. For this reason, USACE considers its role in assessing, communicating and managing risk to be a top priority.
Key Program Definitions
||A man-made structure, usually an earthen embankment or concrete floodwall, designed and constructed in accordance with sound engineering practices to contain, control, or divert the flow of water so as to provide reasonable assurance of excluding temporary flooding from the leveed area.
||A discrete portion of a levee system that is operated and maintained by a single entity.
||One or more levee segments and other features such as floodwalls and pump stations, which are interconnected and necessary to ensure exclusion of the design flood from the associated leveed area.
