The Times-Picayune reports the problem came to light after Hurricane Isaac wrecked nearly 59,000 homes and sent an 11-foot storm surge into southern Louisiana.
That inundation sent thousands of feral hogs onto the levees, where they damaged the flood walls while foraging for food.
We made the repairs, and literally 24 hours later, they ripped up the repairs,” said Giuseppe Miserendino, regional director of the west bank levee authority.
The wild swine can destroy hundreds of linear feet of levee in one night, which takes months to fix.
And since it takes only one small stretch of weakened levee to flood a vast area, officials are concerned.
The Southeast Louisiana Flood Protection Authority-West has enlisted the USDA to assess the full extent of its feral hog problem.
