Slide1

Amphibious Homes: A Real Solution to Flooding?

Fabian

NehrbassSlide2

Sea level rise- floods

Thailand $45 billion dollars damage due to floods in the past two years

Australia $9.6 billion

1.4 million people live in Louisiana’s coastal parishes

634,000 homes

New Orleans sea level rise:

8” by 2030

19” by 2050Slide3

Possible solutions:

Levees

Restoration of wetlands

Sediment use form Mississippi to rebuild land

Abandon land

Adapt!Slide4

Amphibious homes

Allows the home to sit close to the ground, and in the event of a flood, rise up with the rising waterSlide5

Why not just elevate homes?

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 characterSlide6
Slide7

Advantages of floating homes

No loss of character

Cheaper than elevating

No issues with soil subsidence

Less vulnerable to hurricane damageSlide8

Problems with floating homes

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 Slide9

Problems continued

**National Flood Insurance Program will not insure floating houses because they are not considered anchored to the ground**

Chance

they aren’t allowed

In Lakeview, house wasn’t allowed in “special flood hazard zone

More susceptible to wind damage?Slide10

FEMA

SuggestionsSlide11

How it works – Buoyant Foundation Project

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 riseSlide12

Conclusion

No flood insurance, no success

Frequency of storms?

Wind protection?

Float them down the river to Baton Rouge!
