1 Fabian Nehrbass

2 Thailand $45 billion dollars damage due to floods in the past two years Australia $9.6 billion 1.4 million people live in Louisianas coastal parishes 634,000 homes New Orleans sea level rise: 8 by by 2050

3 Levees Restoration of wetlands Sediment use form Mississippi to rebuild land Abandon land Adapt!

4 Allows the home to sit close to the ground, and in the event of a flood, rise up with the rising water

5 Increased vulnerability of the structure to wind damage Elevations are expensive $40,000-$60,000 to elevate vs. $25,000 to retrofit existing house with floating foundation Difficult access to living areas Loss of character

7 No loss of character Cheaper than elevating No issues with soil subsidence Less vulnerable to hurricane damage

8 FEMA does not believe they are a good strategy to protect against hurricane flooding Storm surge can still push water into such a home Still need to evacuate Only work in areas where water rises slowly Size and weight limitations

9 **National Flood Insurance Program will not insure floating houses because they are not considered anchored to the ground** Chance they arent allowed In Lakeview, house wasnt allowed in special flood hazard zone More susceptible to wind damage?

10 Suggestions

11 Shotgun retrofitting Buoyancy blocks and a vertical guidance system interconnected by a light structural frame Utility lines have either long, coiled umbilical lines or self-sealing breakaway connections that disconnect gas and sewer lines when the house begins to rise
