The Kane Mitigation Bank is a 240-acre site which is being turned back into estuary. This is done by erasing the linear canals built a hundred years ago to drain the marsh, and replacing them with a network of small meandering channels that allow tidal water from the Hackensack to penetrate the marsh. A major part of marsh restoration involves clearing out the invasive, non-indiginous phragmites plants that took over the Meadowlands, killing native vegetation. The project is being financed as a mitigation bank: regional transit authorities that build projects in the swamps have to also pay for restoration efforts here. The land is part of the former Empire Tract, 500 acres left undeveloped as part of an exchange that allowed Xanadu to be constructed nearby.
