ABC News commissioned New Orleans photographer William Widmer to visit three neighborhoods in New Orleans immediately adjacent to levees that failed due to Katrina – the Lower 9th Ward, Gentilly and Lakeview.

Pictured: A view of Jourdan Avenue from the Industrial Canal at sunrise, Aug. 2, 2015, in the Lower 9th Ward. Many of the new houses in the area were built through Brad Pitt's Make it Right Foundation.
