10 years after Katrina, a historic marker is erected where floodwall broke in New Orleans

The catastrophic flooding of New Orleans' Lower 9th Ward now has a commemorative marker at the site where a floodwall protecting the neighborhood collapsed, unleashing a wall of water 10 years ago during Hurricane Katrina.

The plaque was erected Monday and will be unveiled at an evening ceremony.

On Aug. 29, 2005, the floodwall along the Industrial Canal catastrophically failed. The resulting flood wiped out the African-American neighborhood and killed scores of people. The marker is located directly in front of where the floodwall collapsed.

Before Katrina, the Lower 9th Ward was a working-class and predominantly African-American neighborhood just outside the city's historic center.

The neighborhood was the birthplace and home to notable artists and musicians. New Orleans legend Fats Domino lived there before Katrina.
