When we started to have kids, my wife and I did not anticipate the cases of
comic books that threaten to take over our house, our sons' pleas for NBA game
tickets at $100 each, or annual university costs approaching what we paid for
our house. And that all occurred over the last 30 years. Imagine trying to look
100 or more years into the future. A hundred years ago, who would have guessed
that Nouvelle Orleans, a quaint French colonial settlement occupying a small,
emergent crescent of land, would become home to 1.5 million people, most of
whom live 1 to 3 meters below sea level? As the saying goes, predicting is tough,
especially the future!
Over the last four days of August, Hurricane Katrina, described by David Brooks
in The New York Times on Sept. 11 as the most anticipated natural
disaster in American history, devastated the Gulf Coast. Damage may exceed
the $200 billion combined cost of the Iraq and Afghanistan wars and reconstruction.
Insurance might cover only one-fourth of the losses. Hurricane Andrew in 1992,
at $38 billion in damages, and the Northridge, Calif., earthquake in 1994, at
$34 billion in damages, are the next two most damaging natural catastrophes
in the United States.
The Katrina and Rita disasters may be symptoms of a larger problem. Our national
zeal for budget cuts has undermined safety because the public infrastructure
(highways, dams, levees, ports and bridges) has substantially deteriorated.
The American Society of Civil Engineers argues that more than $1.6 billion needs
to be spent over the next five years to mitigate further deterioration (only
$900 million has been allocated). Its executive director, Lawrence Roth, told
The New York Times on Sept. 11 that every natural disaster is going
to be more destructive than it needs to be until infrastructure updates
are fully funded.
Government spending on infrastructure that in the Eisenhower, Kennedy and Johnson
administrations averaged about 3 percent of gross domestic product has since
consistently fallen below 2 percent. State-funded infrastructure is in worse
shape. Most federally funded dams are in good shape, but more than 3,500 dams
maintained by state and local governments are unsafe, according to the same
article in The New York Times. Public water systems are currently being
maintained or rebuilt at an annual cost budgeted at $850 million, only a small
fraction of the $11-billion-per-year outlay recommended by the engineering community.
Humankind can learn from past errors to prepare for natural catastrophes. The
1900 storm that devastated Galveston, Texas (killing between 6,000 and 12,000
people), led to the construction of a higher, thicker, granite-block-based seawall
17 kilometers long. Galveston sits on a barrier island 2 to 3 meters above sea
level. After the catastrophe, the entire city was raised 2 meters. Buildings
were jacked up onto stilts and the space beneath was filled in with sand.
Similarly, the Dutch, devastated by a Feb. 1, 1953, storm that collapsed the
levee system in 500 places and drowned 1,800 people, vowed to reengineer their
country, where more than 60 percent of the population of 16 million lives below
sea level. They constructed a massive system of dams, sea walls and sluices,
maintained at an annual cost of $500 million a fraction of a percent
of Katrina's havoc.
But neither Galveston nor the Netherlands are appropriate models for a future
New Orleans. Galveston was deliberately rebuilt mainly as a tourist and entertainment
site. Commerce was wisely transferred to Houston, which remains the banking,
medical, educational and industrial capital of the Gulf. The Dutch had no alternative;
Belgium and adjacent France were not for sale. Realism sometimes triumphs, however.
Pompeii, Carthage and Babylon correctly were left in ruins. We're not even sure
where Atlantis lies!
Nevertheless, we are now swamped with expensive proposals for a new New Orleans.
The New York Times on Sept. 10 included a variety of suggestions from
Bruce Babbitt (Make it an Island), Craig E. Colten (Restore
the Marsh) and Henry Petroski (Raise the Ground). One plan
entails construction of floodgate-protected drainage channels, a new major ship
channel, huge sea gates shielding Lake Pontchartrain from inrushing Gulf storm
surges and revitalization of the city's levee and pump systems.
So, do we rebuild New Orleans, as we foolishly rebuild on the Outer Banks of
North Carolina? Relocating the restaurants, jazz venues, hotels, restaurants
and other businesses 100 kilometers upstream, and leaving only the port and
refinery facilities in place, is more sound geologically, but probably not practical
politically or socially. Reconstructing the city where it is presently centered
will require substantial reengineering of the levee system and restoration of
the surrounding barrier islands and marshes.
I don't think this will end happily, especially in light of the recent discussion
that increases in both the frequency and intensity of hurricanes may be closely
linked to natural ocean circulation cycles and (arguably) global warming (see
story, this issue). Ellen Ruppel Shell, in The Washington
Post on Sept. 4, was right: Americans insist on defying nature
.
the efforts we have made over the years with channels and levees and other great
feats of engineering can contribute to greater catastrophes
. Katrina
has sent us a sweeping message about learning to live with, instead of combating
nature.
I love hurricane cocktails, jazz in Preservation Hall and beignets at Café
du Monde. Chefs at Antoines, Brennans and the Commanders Palace
helped me reach my target cholesterol level of 300! Id love a viable New
Orleans to reappear, but doubt that is a sensible wish.
