The Future of New Orleans?

CNN.com has a page where they have asked readers to give their opinion of how New Orleans should be rebuilt.

Here are some of the best ideas given:

Why not make some of the lower level districts into parks that would serve as flood basins if necessary? The San Fernando Valley in Southern California has (or had) just such a park/flood basin. Also, this would be a great time [to]plan a rail transit system to bring workers in from suburbs located on higher ground.

Create "cells" -- interior levees that isolate potential areas of flooding so that the flooding could be contained within each cell (like on a battleship). Connect the cell walls forming a network of parks, bicycle paths and streetcar lines throughout the city.
