New Orleans Mapped: Post Katrina

Five years ago New Orleans was devastated by floods caused by Hurricane Katrina. It was one of America's worst ever natural disasters.

Whilst some areas, such as the French Quarter have recovered and other areas are being rebuilt, some areas, like the New Orleans East area are still almost completely abandoned. The New Orleans East area used to have a population of more than 100,000 it now has a population of around 7,000.

Back in 2005 Nova created a New Orleans Flood Map that allows you to view an overlay of the flood over your home town. The map now looks very basic but it is still an effective way to visualise the sheer scope of the floods.



If you zoom in on your part of the U.S. you can see the overlay superimposed on your home. The blue overlay only shows flooding in New Orleans proper. Additional flooding occurred in other suburbs.

New Orleans Repopulation Map

162,115 households received mail in June 2010, in New Orleans, compared to 203,457 in June 2005. The U.S. Census Bureau's methods for estimating population can't keep up with the extraordinary situation post-Katrina so looking at residential addresses actively receiving mail is one way that population can be estimated.

This map from the Greater New Orleans Community Data Center shows residential addresses actively receiving mail by census block in New Orleans. The mailing list data represents the number of residential addresses per block where the mailman knows someone picks up the mail.

The map shows the population density in June 2010, the darker the shade the higher the density. If you zoom in on a block you can see the June 2005 households compared to the most recent figures.

New Orleans Redevelopment Authority

The New Orleans Redevelopment Authority are using Google Maps to help show the condition of properties in New Orleans.

The Authority's Project Search lets you search for projects and current Requests for Proposals in its database. If you search for a New Orleans neighborhood you are presented with a list of properties. If you click on the 'more details' link next to a property you can view photographs of the property and view its location on a static Google Map.
