This combination of Sept. 11, 2005 and July 29, 2015 aerial photos show the Lower Ninth Ward of New Orleans flooded by Hurricane Katrina and the same area a decade later. Before Katrina, the Lower Ninth Ward was a working-class and predominantly African-American neighborhood just outside the city's historic center. (AP Photo/David J. Phillip, Gerald Herbert)
