Building a storm surge protection system along the Texas Gulf Coast could cost between $7.9 billion and $11 billion, and likely would not be completed for about two decades, according to a new study.
The report by the Gulf Coast Community Protection and Recovery District, which includes six counties along the upper Texas coast, comes after years of urging by academics to take action to prevent a massive storm surge like the one spawned by Hurricane Ike.
The study analyzed the costs and benefits of a range of major infrastructure projects – from systems of levees to a giant gate in the Houston Ship Channel.
Robert Eckels, the district president, said even with the highest cost estimate of $11 billion, paying for surge protection is still far cheaper than the aftermath of Ike, which caused more than $30 billion in damage when it hit in 2008.
“Just the damage from Ike is more than double even what the most expensive alternatives are,” Eckels said.
But the study is likely to reignite a debate over how to best balance protecting the coast with the potential harm to the environment posed by artificial barriers.
The most expensive proposal, with a construction cost of $5.8 billion, involves building a 55-mile storm surge protection system that includes a massive navigation gate across the Houston Ship Channel. The alternative, at $3.5 billion, involves a series of separate systems that would not provide direct protection to the upper reaches of the ship channel.
We’ve been talking about this for years now, and while there’s no consensus on what the best course of remediation is, there’s definitely a consensus that a worst-case storm is a real if small possibility, and its effects would be devastating. Take a look at the Hell and High Water interactive slideshow put together by the Trib and ProPublica if you want to freak out a little. Of course, the first problem that has to be solved for this is how to pay for whatever we decide to do. I personally think that a combination of federal and state funds should be the source, but we can quibble over who pays how much for what. But first, we need to agree to Do Something. The rest can work itself out once we take that step. Swamplot has more.
