Coastal Communities: Vital to U.S. Economies
Coastal watershed counties contain 52% of the nation's population
-- but account for less than 20% of US land area (excludes
AK).
45 % of the U.S. national gross
domestic product is contributed by
coastal communities
Coastal tourism and recreation accounted for $89.2B between
2005-2010
Why should we all care?
This graphic illustrates the truck flows from the Port of New
Orleans and shows how far goods spread from one port. It also
speaks to patterns of development in this country.
Coastal risk is not a special interest. We are a coastal nation --
even in the heartland, Americans are connected to the coast.

Billion Dollar Disasters: Fact of Life
This chart illustrates the publically and privately reimbursed
entities that have physical and fiscal losses, environmental and
social costs are not depicted here.
These events and disasters are impacting dense populations where a
large portion of the economy is generated
Trend line of this graph shows acceleration of damages in the last
few years.

What is risk? It is a function of geography, geomorphology,
cultural frameworks, risk perception.

Sandy: A Turning Point?
Aftermath of Hurricane Sandy shows possibilities of change in the
conversation on rebuilding.
No one-size-fits-all approach: rebuilding strategy for NY will be
different from NJ. In NJ, mom and pop shops and shore towns are
half of that area’s revenue which presents challenges if they can’t
bring in money by Memorial Day.

Will Your Business Be Open Tomorrow?
The yellow building was built with standard construction
techniques. The green building was built of the exact same
materials but a different, more wind-resistant construction
technique. The green building cost $3000, less than 5% more, to
build.
The top wind gust during the test was 136 mph or the equivalent of
a 97 mph one-minute sustained wind speed. All wind speeds are
referenced to standard open country conditions at an elevation of
10 m (33 ft.).
At what wind speeds did the following components on the
common practice construction building fail?:
Flashing: 73 mph wind gust, which is the equivalent of a 52
mph one-minute sustained wind speed
Roll-up Door: 115 mph wind gust
Wall: after the 2×4, which simulated a tree branch, shattered
the window, the wall separated from the building during a 110 mph
wind gust, which is the equivalent of 79 mph one-minute sustained
wind speed.
Note the importance of window protection: Before the window was
broken the building’s walls survived a 136 mph wind gust, which is
the equivalent of a 97 mph one-minute sustained wind
speed.
The buildings were set up as diners, with “inventory” placed in the
back. The inventory in the yellow building was ruined, the
inventory in the back of the green building was only
displaced.
