The Advocate – Worst-case sinkhole scenario would reroute Bayou Corne
Texas Brine Co. has developed a backup plan to replace the cracked southern section of a protective levee surrounding the sinkhole in northern Assumption Parish and may look to reroute Bayou Corne if conditions deteriorate further, records show.
The company’s new draft plan, filed this month with regulators who are still reviewing it, proposes “triggers” that would prompt the levee replacement. It also outlines an alternative of rerouting Bayou Corne if a replacement levee proves too unstable to maintain due to sinking of the remaining land between the sinkhole and the bayou. . . .
. . . a new southern levee farther from the sinkhole, would be built if the existing levee drops 4 feet in 30 days even after planned repairs or if testing shows the underlying earth is too unstable for repairs, Texas Brine’s plan says.Once the company determined it had to move the southern levee, it would then develop plans to reroute the bayou. . . .
