It wouldn't cost anything if the developers were successful. That is a big if.
If not, it would be guaranteed by the Federal Government, and come right out of our pockets.
Personally I'd like to see most of those properties turned back into wetland, but even so, the owners are entitled to full compensation because the land will be taken for a public use.
Which is more economical, 60 cents on the dollar now, or 100 cents on the dollar plus legal fees later?
