2. US Army Corps of Engineers BUILDING STRONG ®

3. 4 Nations’ Agencies  Explore risk-informed flood risk management approaches  Continue ongoing collaboration  Learn from others’ experiences

4. BUILDING STRONG ® Flood Risk Management Approaches Flood Risk Probability of flood hazard Vulnerability of individuals, society, environment Consequences

5. BUILDING STRONG ® Country Context Japan  Many assets, population in floodplain  Short time to flooding Netherlands  Major part of country is flood prone  Densely populated  Reliance on structural measures United Kingdom  Transition from flood defense to risk management  More holistic approaches United States  Many federal, state, others sharing responsibilities  Transition to risk-informed approaches

6. BUILDING STRONG ® Commonalities - Challenges  Adapting to new understanding of flood risks ► Climate Change ► Land-use decisions and flood risk management  Communicating with the general public ► Residual risk ► Promoting individual and societal responsibility  Aligning planning with action ► Identifying and meeting most critical risks ► Ensuring social, environmental, economic, political acceptability

7. BUILDING STRONG ® Commonalities - Approaches  Examining implications of climate change on flood hazards, vulnerabilities, consequences  Emphasizing communications and outreach  Increasing attention to environmental impacts and opportunities in flood risk management  Focusing on various aspects of cycle of emergency management

8. BUILDING STRONG ® Differences – Protection  Netherlands: specifies (risk-based) legislated level of protection  Japan: sets long-term aspirational goals for levels of protection along major rivers  United Kingdom and United States: use risk analysis informs decision-makers about options available to them

9. BUILDING STRONG ® Differences – Insurance  United States and United Kingdom: support separate flood insurance programs (provisions of the programs differ)  Japan: includes floods in comprehensive household insurance (government does not offer flood insurance)  Netherlands: government does not offer flood insurance

10. BUILDING STRONG ® Netherlands’ VNK Project Failure Mechanisms Levee Failure Probabilities and Consequences Prioritizing Levee Reinforcement measures (Levee System 36) Number of Fatalities (expected value) Levee System 36 Probability (per year)

11. BUILDING STRONG ® National Flood and Coastal Erosion Risk Management Strategy (England) Goal: “To ensure that the risk of flooding and coastal erosion is properly managed by using the full range of options in a co-ordinated way.”  Community focus and partnership working  A catchment and coastal ‘cell’ based approach  Sustainability  Proportionate, risk-based approach  Multiple benefits  Beneficiaries should be encouraged to invest in risk management Guiding Principles:

12. BUILDING STRONG ® Japan’s Suibo Activities  Activities executed by suibo-dan (local flood-fighting team) ► Normal days: preparation of flood-fighting storage, communication tools, flood drill (265,000 mobilized in 2004) ► During flood: warning, patrol, levee protection activities (900,000 in 2011)  2005 Suibo Act to enhance ability of local communities

13. BUILDING STRONG ® Conclusion and Next Step  Collaboration resulted in ► Sept. 2011 joint report ► Greater awareness and understanding ► Ability to leverage events and perspectives  Continuing to engage in mutually- beneficial international partnerships ► International Levee Handbook ► Interchange ► “Lessons learned”
