INVENTORY/INFORMATION
PROGRAM

• “Authoritative Database that Describes the
Location and Condition of the Nation’s Levees, and the Potential Consequence Behind Those
Levees”

• 2007
– “SEC. 9004. INVENTORY AND INSPECTION OF LEVEES.
– (a) LEVEE DATABASE.— (1) IN GENERAL.—Not later than one year after the date of enactment of this Act, the Secretary shall establish and maintain a database with an inventory of the Nation’s levees. (2)
CONTENTS.—The database shall include—
• (A) location information of all Federal levees in the Nation (including global information system information) and, for non-Federal levees, such information on levee location as is provided to the Secretary by State
and local governmental agencies;
• (B) utilizing such information as is available, the general condition of each levee; and
• (C) an estimate of the number of structures and population at risk and protected by each levee that would be adversely impacted if the levee fails or water levels exceed the height of the levee.

• The National Levee Database was initially designed between USACE and FEMA
• Common Theme:
– Create a database
– Obtain inventory and relevant information on all levees in the United States
– Create program to communicate levee information to stakeholders
• Basic Components of NLD Program
– Database
– Inventory/Information (inputs)
– Inventory/Information Applications (outputs)

• Current State
– Developed as a tool to allow external stakeholders the ability to contribute and manage their levee data to establish a comprehensive levee inventory
• Target State
– Real-time data integration with NLD
– Allow users to import levee data from existing data sets (e.g., .shp, excel, and
PGDB files)
– Provide auditing and change management capability for user submissions
– Standardized review/approval process
– Complete comprehensive levee inventory
– Target Completion Date August 2011

NLD Applications
Public View – Information, Reports, Maps
• Allows stakeholders ability to view and run various reports, maps and access other information.
– Levee within certain state, city, county

• OGC Web Services
– complies with open standards for geospatial data exchange.
• Water Management Applications
– information useful for water management including levee height, water gages, and real time weather information
• Levee Screening Process
– Tool used to assess relative risk and other important information concerning levees

• Kansas City Flood Fight June 2010
• NLD Served(s) as the ‘One-Stop’ data source for all federal and non-federal levee information
• Maps and reports produced using NLD data were exported from the local system (CorpsMap +
Sharepoint) to Google Earth
 for distribution throughout USACE and to external emergency management agencies such as Missouri SEMA

The map information is exported from CorpsMap to Google Earth just prior to the CMT briefing.
Links to all information are included, such as the CMT briefing packet and photos of field conditions. All necessary files are managed on Sharepoint for internal USACE use. In June 2010 FTP was used to provide all information to
EMAs, but in the future NWK will use a Sharepoint Extranet.

Some Helpful Feedback Today
• How concerned are you or the tribes you represent about levees?
• Are there other organizations or tribes you think might be interested in hearing about the
Committee or levees?
• Any thoughts about emergency management programs we might look to that are good examples of how to involve tribes?
