Location and Condition of the Nation’s Levees,
and the Potential Consequence Behind Those
Levees”
Authorities
• 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.

OBJECTIVES AND NLD
• 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)

NLD INVENTORY/INFORMATION
Census Tool
• 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

USACE
• Levee Inventory Tool
• Tool used by USACE Districts
• USACE Progress to date:
• Known miles today
• Miles Completed
• Miles under contract

APPLICATIONS
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
NLD Applications
• 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
NLD Applications
USACE Kansas City District
Emergency Management
• 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
NLD in Google Earth 

NWK Civil Boundary
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?
