1. Integrated Ecosystem Restoration and Hurricane Protection: Louisiana’s Comprehensive Master Plan for a Sustainable Coast

2. Agenda Coastal Louisiana is unique. The Master Plan is Louisiana’s framework for sustainability. The Master Plan is comprehensive and innovative. The Master Plan is unprecedented.

3. Coastal Louisiana is unique.

4. Landscape at Risk

5. Assets at Risk Largest fishery in Lower 48 States A significant role in reducing hypoxia problems in the northern Gulf of Mexico Nearly one-third of the nation’s oil and gas supply originates or is transported through coastal Louisiana Connected to nearly 50% of nation’s refining capacity Largest port complex (by tonnage) in the world

6. Communities at Risk At risk from a storm that has a 1% chance of occurring in any given year: –Over 430,000 residences –Potential economic consequences of $34 billion coastwide At risk from a storm that has a 0.2% chance of occurring in any given year : –Over 871,000 residences –Potential economic consequences of $157 billion coastwide

7. The Master Plan is Louisiana’s framework for sustainability.

10. Restore Sustainability to the Coastal Ecosystem Caernarvon Diversion Clay deposition on organic marsh surface

11. Maintain a Diverse Array Habitats for Fish and Wildlife

12. Sustain Louisiana’s Unique Heritage and Culture Scott Russell

13. Technically Sound, Publicly Acceptable Maximized use of available information by partnering with other planning efforts –USACE –Louisiana Recovery Authority Incorporated findings of technical evaluations of system performance. Provided opportunities for intense stakeholder and public engagement Incorporated rigorous scientific and technical participation and review –Interdisciplinary Technical Team –Science and Engineering Review Team –Louisiana Coastal Area Science Board

14. The Master Plan is comprehensive and innovative.

15. Technical Challenges Climate Change –Sea level rise –Changes in rainfall patterns Integrating hurricane protection systems into a sustainable landscape Combined effects of multiple river diversions Functionality of marsh restoration using dredged material Sediment availability for wetland restoration and hurricane protection systems Nutrient concentrations in the Mississippi River

16. Restoring Sustainability to the Coastal Landscape Maximizing use of the Mississippi River and its resources –Restoration of system hydrology –Land-building diversions –Land-sustaining diversions

17. Restoring Sustainability to the Coastal Landscape Sustaining critical landforms –Hydrologic control of navigation channels –Marsh restoration with dredged material –Barrier shoreline restoration –Ridge habitat restoration –Shoreline stabilization

18. Sustainable Restoration: Delta Plain

19. Sustainable Restoration: Chenier Plain

20. Reduce Risk to Communities Restored ecosystem Non-structural measures –Elevated homes and businesses –Improved building codes –Evacuation planning –Land-use planning –Hazard mitigation plan implementation –Insurance Levees and flood gates

21. Modification of Existing Levees: Plaquemines Parish

22. Feasibility Study Complete: Morganza to the Gulf

23. Feasibility Study In Progress: Donaldsonville to the Gulf

24. Reconnaissance Study Complete: Southwest Coastal Louisiana

25. Included in LACPR: Lake Pontchartrain Barrier Plan

26. Other Important Plan Elements Outlines the Louisiana Applied Coastal Engineering and Science Program Recommends key changes to policy and legislation –Land use planning –Land rights acquisition –State government structure Outlines an adaptive management strategy

27. The Master Plan is unprecedented.
