PB,

Re: What we going with all the excess soil??

I was thinking about that as I was creating my perfect fantasy of underground utility heaven.

As you know, New Orleans is fifteen feet below sea level. The obvious use for the spoils of our utility tunnels is to ship the aggregate to southern Louisiana where it can be reinjected in a process colloquially called "mud jacking" under the city at high pressure in order to ever so slowly raise the city from the depths. About eight inches a year ought to be a rate at which the entire city could be lifted with not much more than a few cosmetic plaster cracks.

The other application for the material is to rebuild the outer islands of the Mississippi Delta which are in danger of washing out to sea, and further threatening New Orleans and the oil & gas infrastructure of the region.

Of course, there would be a slight negative impact on the immediately local fisheries, but those displaced Cajuns might just be happy to work on a project that makes sure their homes don't get swept out to sea in the next major hurricane.
