In this Thursday, March 23, 2017 photo, students and faculty from Northwestern University and the University of Illinois work on a home in the Lower 9th Ward that was being built by Habitat for Humanity, in New Orleans. A major rebuilding effort is underway in the New Orleans neighborhood decimated by Hurricane Katrina in 2005. Officials and some residents hope the houses planned for the Lower 9th Ward will bring in new residents and spur economic development, but others have concerns. (AP Photo/Gerald Herbert)
