Retreating from the Beach: Easier Said Than Done

There’s an Op-Ed from Professor Orrin H. Pikey in the November 15, 2012 New York Times. Here’s some “fair use” of that article.

We Need to Retreat From the Beach

By ORRIN H. PILKEY

Durham, N.C.

AS ocean waters warm, the Northeast is likely to face more Sandy-like storms. And as sea levels continue to rise, the surges of these future storms will be higher and even more deadly. We can’t stop these powerful storms. But we can reduce the deaths and damage they cause.

Hurricane Sandy’s immense power, which destroyed or damaged thousands of homes, actually pushed the footprints of the barrier islands along the South Shore of Long Island and the Jersey Shore landward as the storm carried precious beach sand out to deep waters or swept it across the islands. This process of barrier-island migration toward the mainland has gone on for 10,000 years.

Yet there is already a push to rebuild homes close to the beach and bring back the shorelines to where they were. The federal government encourages this: there will be billions available to replace roads, pipelines and other infrastructure and to clean up storm debris, provide security and emergency housing. Claims to the National Flood Insurance Program could reach $7 billion. And the Army Corps of Engineers will be ready to mobilize its sand-pumping dredges, dump trucks and bulldozers to rebuild beaches washed away time and again.

But this “let’s come back stronger and better” attitude, though empowering, is the wrong approach to the increasing hazard of living close to the rising sea. Disaster will strike again. We should not simply replace all lost property and infrastructure. Instead, we need to take account of rising sea levels, intensifying storms and continuing shoreline erosion.

This is not the time for a solution based purely on engineering. The Army Corps undoubtedly will be heavily involved. But as New Jersey and New York move forward, officials should seek advice from oceanographers, coastal geologists, coastal and construction engineers and others who understand the future of rising seas and their impact on barrier islands. We need more resilient development, to be sure. But we also need to begin to retreat from the ocean’s edge.

 

I agree with much of what it has to say. But …

Eight Reflections on Sandy

1. Turns out a Category 1 hurricane can, under the right circumstances, do a heck of a lot of damage. So can tropical storm force winds.

2. Up until this week, New York City and New Jersey could (and, for all I know, did) make the sort of arguments that would have kept insurance reserves available to pay for Sandy far too low.  The argument would have been: no tropical cyclone has made landfall in New Jersey as a hurricane in 109 years, therefore the risk is low.  Acceptance of those arguments can result in greater insurer insolvency and policyholder shortfalls. Turns out the theoretical flaws with that kind of argumentation, which we hear from some Texas coastal politicians all the time, can come back to bite you in the rear.
