This month marks 20 years since the failing and faulty U.S. Army Corps’ levees overwhelmed the city of New Orleans after Hurricane Katrina hit. At The Lens, our journalists have spent the past year researching and writing about the impacts the flooding had on the city’s citizens. The flooding resulted in power outages and transportation failures throughout the city, making the emergency response to the storm even more difficult. Our guests this week include Pulitzer-prize-winning environmental journalist and Walton Family Foundation Fellow Mark Schleifstein and The Lens’ environmental reporter Delaney Nolan. You can also listen to Behind The Lens on Apple Podcasts, Spotify and other services.
