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 2030 19 by 2050
Levees Restoration of wetlands Sediment use form Mississippi to rebuild land Abandon land Adapt!
Allows the home to sit close to the ground, and in the event of a flood, rise up with the rising water
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
No loss of character Cheaper than elevating No issues with soil subsidence Less vulnerable to hurricane damage
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
**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?
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
