It's acknowledged all over the world residents of the New Orleans region were enormously affected by the Federal Levee Breaches six years ago.
But few are aware that the breaches prompted nearly a dozen changes to national policy and practices. Those changes include the first ever nationwide Levee Safety Program and the first ever nationwide Levee Data Base (NLD).
This is why Levees.org has undertaken the years-long process of listing the breach sites to the National Register of Historic Places.
The national impacts of the horrific breaches is important because the majority of Americans (55%) live in counties protected by levees. This represents about 157 million people.
(Levees.org discovered this important information in a request to FEMA under FOIA).
The New Orleans Ladder recently commissioned disaster geographer Ezra Boyd to create an interactive map using this levee data. By clicking on the icon above, you can access this free interactive map which provides details about levees in every state.
