How New Orleans is trying to save its homes from flooding

Hurricane Katrina killed over 1,800 people and flooded many homes in New Orleans. In the aftermath, a quarter of the city's housing stock was abandoned. The U.S. spent billions to redevelop and protect the city. But more may be needed to counteract the city's slow decline into the sea. On top of that, parts of the federal response have been criticized for their impact on low-income homeowners. Today, the city is facing a housing crisis as insurance premiums and property taxes rise.
