OK, I'm an outsider on this, but it sounds like this is a case of insufficient funds sent to an ILF to mitigate for impacts to wetlands, which resulted in temporal loss of wetland functions as the (first) organization tried and failed to find appropriate mitigation. It took 11 years to seal the deal and finally spend the mitigation funds. Geez!
The first set of funds were set aside in 2001 for a railroad impact of 11 tidal acres - the total of $57,194 breaks down to ~$5,200/acre. Compare that to wetland mitigation tidal bank credits going for hundreds of thousands of dollars per acre in other parts of the country.
Later on, from 2005-2007, another $44,150 was put into the mitigation kitty from another 8.3 acres of impact (= $5,319/ acre).
And then later in 2009, an unspecified amount of impacts from road-building added an additional $180,000 to the mitigation funds.
A land trust had the funds for 8 of the 11 years, the Conservation Fund took over in 2009, and "the sale is now final" in 2012.
Let me know if anyone out there can fill in this story more.
