The National Levee Database captures all known levees in the United States. It provides users with the ability to search for specific data about levees and serves as a national resource to support awareness and preparedness around flooding.
The database is intended to help decision makers understand levees - including their location and condition. This information can be used to identify critical levee issues, focus priorities for funding, understand the true cost of maintaining levees, support community preparedness, and quantify the nation's flood exposure.
