- 1. CHANGING CLIMATE – RISING TIDE
- 5. Large Scale Stormwater Wetland
- 17. Charles Darwin: “It is not the strongest species that survive, nor the most intelligent, but the ones most able to adapt to change.” Organizations inspired by nature are resilient, optimizing, adaptive, systems-based, values-based, and life-supporting. The more resilient an organization is, the more able it is to successfully deal With disturbances and volatility.
- 19. Case Study • Greater New Orleans post-‐Katrina Infrastructure and Coastal Restora?on System – Biggest Untold Story of Success and Possibility! – Massive undertaking can serve as example for Climate Change Adapta?on Measures to reduce actual risk— not just insure financial exposures – Started in 2007, func?onal in 2011 –AMAZING!! – U?lized Expedited NEPA – During Hurricane Isaac in 2012 avoided damages far greater than its cost – an excellent ROI
- 21. Plan Formula?on • Congress Mandated 1% annual risk • What is service life? Steel/Concrete = 50 yrs • What will condi?ons be at END OF SERVICE? CHANGED! • How to op?mize budget provided? • Project Re-‐Defined Risk-‐Based Infrastructure Formula?on • Factored in SLR, subsidence, etc • Forecasts for basis of design • Truly systems-‐based approach of hard and green • Not just 1% chance of flooding TODAY as is typical • End of service 1% chance of flooding • PLUS resilience for 500-‐yr storm throughout and beyond
- 23. Design Criteria • SLR, Weather and Hydraulics • Frontal ocean assault >>> wind forces • Water where? (subsidence, surge, waves, etc) • What can it carry? (?mbers, ships, structures) • Durability and Synergy • Structural strength requirements • Design eleva?on requirements (wet and dry) • Interac?on of elements (weak links, complementary) • HSDRRS Criteria for system and elements
- 24. The Elements • Mul?ple Lines of Defense – Linear Infrastructure: Levees, Walls, Gates, etc – Natural sun-‐gathering ecosystems – Landforms as barriers, self genera?ng – Behavior: Evacua?on, pumps, raised buildings, etc • Adap?ve Management – Works for different storm events today – Capable of performing and evolving over ?me – Designed for modified structures and opera?ons – Could address scenarios not currently known
- 25. Dune and Marsh Plahorms
- 27. The biggest and best results are not visible • New Ways to Collaborate – Government ↔ Industry – Government ↔ Public – Government ↔ Researchers • New Ways to Communicate – Risk and Uncertainty – Future Scenarios – Transparency and Verifica?on
