From the U.S. Army Corps of Engineers:
The U.S. Army Corps of Engineers (USACE) today opened the updated National Levee Database (NLD) for public access. The NLD is a living, dynamic information source that provides visualization and search capability on the location and condition of levee systems nationwide.
“The National Levee Database is a public view into the information that builds understanding of the benefits and potential risks levees pose for the communities in which they exist,” said Eric C. Halpin, P.E., USACE deputy dam and levee safety officer. “The database now contains levee information within the USACE program, FEMA, and other states and federal agencies. We continue to work closely with additional federal, state, and local agencies and tribes to include the information about other levees on a voluntary basis.”
The database includes attributes of levees and floodwalls relevant to flood fighting, design, construction, operation, maintenance, repair and inspection. Because the location and characteristics of levee systems can be viewed on a map with real-time data from other sources, such as stream gauges and weather radar, it is a useful tool for a variety of public agencies and individuals including flood plain managers, emergency management agencies, levee system sponsors and citizens who live or work behind a levee.
Currently the NLD includes information on approximately 33,000 miles of levee, which includes 14,500 miles of levees systems associated with USACE programs, 15,000 miles from the FEMA mid-term levee inventory and several other states and federal agencies.
