Commenter SM mentions the Mercatus work. In case people don't know where that is, you can find it here.
The Urban Institute also had a major post-Katrina research effort. You can find that work collected here. I contributed to one of those reports, although it's a less interesting one - it was a feasibility study for Katrina research... so more behind the scenes research planning than anything else.
