Flood risk and the levee conditions can change over time. Levee banks can erode, closures rust, animals dig tunnels, and pumps wear out. To ensure that levees work properly during a flood, constant watchfulness is necessary.
USACE regularly inspects levees as part of its Levee Safety Program. These inspections help monitor the overall condition of the levees, find problems or weaknesses, make sure necessary maintenance work is being performed, determine if the levee qualifies for federal assistance for repairs (Public Law (P.L) 84-99 Rehabilitation Program), and provide information to the public who rely on these levees.The inspection information is also used to assess the risk of flooding.
