At risk from rising seas, Norfolk, Virginia, plans massive, controversial floodwall

The city is now moving forward with a massive floodwall project to protect itself, in partnership with the U.S. Army Corps of Engineers. The project will include tide gates, levees, pump stations and nature-based features like oyster reefs and vegetation along the shoreline. It's one of the biggest infrastructure efforts in city history – and an example of projects the Corps has proposed up and down the U.S. coastline, from New York to Texas.
