The “Ike Dike”, a network of dikes and gates off the coast of Galveston that was first proposed last year by William Merrell as protection against storm surges from future hurricanes, is being discussed more seriously by the Gulf Coast Community Protection and Recovery District.
Although the Ike Dike may not be the final solution — environmentalists have raised concerns about the effect of gating off Galveston Bay and the project’s potential to spur development in sensitive areas — Merrell is happy there will be a comprehensive study of the issue.
“It will get a fair shake,” Merrell said of the Ike Dike.
“During this process everyone gets a chance to get their two cents in. My goal was to make sure this got on the table and that it got a fair hearing. Now that’s happening and I couldn’t be more pleased.”
A new report released last week by Rice University’s Severe Storm Prediction, Education and Evacuation from Disasters Center bolsters the case for doing something to mitigate storm surge, said Phil Bedient, the center’s director, who co-authored the report with environmental attorney Jim Blackburn.
“It’s pretty clear that we now really need to have a serious discussion about how to defend and mitigate against surge as best we can. You can’t completely protect an area, but you can reduce the risk,” Bedient said.
The report reinforces the notion that Ike could have been worse. Had it struck 30 miles down the Texas coast, for example, the surge at the Port of Houston would have been 19 feet, instead of just over 13.
It’s scary to think that Ike could have been a lot worse, isn’t it? Blackburn was one of the ones raising environmental concerns about the dike approach, so alternatives will get a fair hearing as well. The website for the Severe Storm Prediction, Education and Evacuation from Disasters Center (SSPEED) is here. You can read their full report here, an overview of some of its findings here, and a brief status report here. To me, the key bit is this from that last link:
Dr. Merrill has estimated the Galveston portion of the Ike Dike to cost roughly $3 billion, or only 5-6 cents of property tax for residents in the affected counties over the next 30 years. Wayne Klotz, president of the Houston engineering firm Klotz Associates Inc., believes the estimate is higher at around $7 billion to $10 billion. Whatever the final cost may be, advocates believe there is a high benefit to cost ratio for such a project when financial consideration is given for the structure’s potentional to prevent future damage.
Even at the high end, $10 billion is a relatively small amount, which would be amortized over decades and which would have long-lasting benefits. Cost is always a consideration, but if that’s the most expensive scenario, it shouldn’t be an obstacle.
