re: Will the astronomical rise in homeowners/flood insurance empty out the Southshore?

I guess in the end, classical economic theory will simply make property values go down to a level such that the net cost (i.e., including insurance) will equal that of a somewhat nearby with normal insurance costs. That said, at some point, folks would need to go to Shreveport or Jackson (MS) to get normal costs (i.e., because at least by then, hurricanes are not destructive).
