As much as I hate to refer to cities like Detroit when talking about solutions for New Orleans, once in a while there is a reason to do so.
The thing about Detroit to keep in mind is that it is significantly smaller in square miles than New Orleans. About 37 miles less.
I bring that up because I think many of us think of Detroit as this huge city with out of scale empty factories everywhere. And that is true in some areas, but not all.
So, once again, scale is the key to success and this project shows it by dealing with one street as a project and adding ideas as they go.
