Description

The National Levee Database (NLD), developed by the U.S. Army Corps of Engineers (USACE), is the focal point for comprehensive information about our nation's levees. The database contains information to facilitate and link activities, such as flood risk communication, levee system evaluation for the National Flood Insurance Program (NFIP), levee system inspections, flood plain management, and risk assessments. A comprehensive inventory of the nation’s levees serves as a key resource for USACE and sponsors to share information related to their levees. The NLD continues to be a dynamic database with ongoing efforts to add levee data from federal agencies, states, and tribes. The database is only as good as the information that it contains with continual efforts needed to assure that the information is correct and current.

Background

Information associated with Public Law 84-99 Flood Risk Management Systems have been field surveyed and entered into the National Levee Database. The Rock Island District has completed entering information on over 825 linear miles of these qualifying levee systems along the Upper Mississippi River and tributaries.

Status
Quality assurance, updates, and adding additional types of information need to be performed.

Major Work Item Prior Fiscal Year

FY 2021: No funding was received in the FY2021 budget allocation.

Major Work Item Current Year

FY2022: If funded, work will proceed with developing and revising the NLD. The district has reviewed many levee systems that have inaccurate or missing information. The funding allocation would be used to update the NLD such that it reflects the best understanding of our levee system features. Additionally, risk characterization summaries would be added for each federally constructed levee system.
