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

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  Click the Corps Logo for links to all CMT maps and reports Lake status Levee damage points 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?
