2. What is Flood Inundation Mapping?
Flood Inundation Mapping (FIM) is a real-time,
operational tool that visually relates USGS
streamgage readings and NWS forecasts to flood
risk for the primary purpose of public safety, but
also has significant benefits of:
• Understanding changing natural processes that
produce hazards
• Development of hazard mitigation strategies and
technologies
• Effectively reduce vulnerability and repetition of
loss to infrastructure
• Promotion of risk-wise behavior
3. Overview
• Review of NWS Flood Inundation Mapping
Program
– Current locations and planned future work
• Review of USGS Flood Inundation Mapping
Initiative (FIMI)
– Current and future work
• Review of Collaborative Projects between
NWS and USGS
– Incorporation of maps into HAZUS

NWS Stakeholder Surveys
• Public wants Common Tools and Features such as
Google
• Emergency Managers need Enhanced Decision
Support Tools to support Weather Ready goals
• According to recent NWS CFI customer survey,
responses increased by 250%.
• The number of respondents who claimed to be a
personal user increased from 8 to 21 thousand or
roughly 64% of all respondents.
• The number of respondents for Emergency Response
remained consistent.

12. FIMI Web Mapping Application
“New” Features
• Decision Matrix – ability to show
two linked dependent sites for one
reach
• WaterAlert
– Subscribe in the application
• WaterWatch
– Set the historical context for
current flows using another USGS
product
• NWS forecast linkage
– Working on which forecasts and
how to display
• SharePoint form for submission of
libraries from USGS WSCs
13. Next Steps in Products and
Communications
• Toolbox and Map libraries
– Continue to elaborate on the guidance and templates as
needs arise through the pilot projects and
cooperator/partner needs
– Add NWS Inundation Libraries and more links to AHPS
• Continue WMA development
– Integrate more seamlessly with NWS forecasts
• Combined live hydrograph and APTIS uncertainty communication
ideas
– Integrate with more NWS tools and web services
– Work on including HAZUS information
and maybe Dynamic Mapping
– Explore print feature further with the SPN

Enhance inter-agency collaboration to better
communicate flood risks and reduce repetitive flood losses

17. USGS Hazus-MH Assessments
Initial Results
• USGS has processed large percentage of the NWS AHPS FIM
Shapefiles and Depth Rasters
• Half of the Initial Results show 1 to 4B dollars in financial exposure
• Delaware River at Trenton, NJ had potentially 40,00 people at Risk
• Iowa River at Iowa City had 3B dollars at risk

18. NWS AHPS FIM Lessons Learned
Cost Savings by Partnering
Costs go down Efficiency goes up
• Additional cost to complete one inundation map library as part of a FEMA
FIS or local Riverine Flood Study: 5 – 10 K (~5 to 10% cost increase)
• Cost doubles and time increases if inundation map library is created after
the study is completed: 15 – 20 K
• Develop inundation libraries in conjunction with Flood Study yields
significant user benefit for small incremental cost and address map
maintenance for local communities

19. NWS AHPS and
USGS FIMI Lessons Learned
Cost Savings by Partnering
Costs go down Efficiency goes up
Phase 3 cost to implement one inundation map library:
Current Implementation
• on NWS AHPS via current interface: 8K
Proposed Implementation
• on NWS AHPS Google interface: estimated 3-5K (Public)
• on USGS FIMI Web Mapping Application: 1.5 K * (Power-user)
* Need to be evaluated for web traffic, bandwidth, and high loading.

27. Notional Plan & Timeline
Phase 1 (FY2011-12)
• Begin Level 1 HAZUS flood risk analyses for (~60) NWS Inundation Mapping
Locations, (FEMA/USGS)
• Add pilot HAZUS capability to FIMI Web portal. Begin development of manual
with standards and guidelines for new site development.
Phase 2 (FY2012-13)
• Complete and QA/QC Level 1 HAZUS analyses.
• Based on evaluations from Phase 1, develop Level 2 HAZUS capability for a
selected subset of the 60 NOAA/NWS sites.
• Draft manual with guidelines and standards for new site development
Phase 3 and beyond….TBD

Population and Dollar Value of Assets
29. The Path Forward
• Commit to a Prototype Demonstration for Flood
Inundation Web Mapping Services, which will link real-
time observations, flood forecasts and warnings, and FIM
with geospatial flood hazard information from FEMA’s
HAZUS program prior to December 31st.
• Collect available resource to design, develop, implement
subsequent prototype demonstrating coastal components
of the Flood Inundation Mapping Tool.
• Work towards common standards for flood inundation
mapping products, such that shapefiles and rasters can
be shared and consumed by various viewers for the public
and power user.
