Crosswinds Marsh Preserve

There is an excerpt from a website:
Crosswinds Marsh is one of the largest man-made wetlands in the country. It was built to replace the wetlands that were going to be paved over to expand Wayne County's Detroit Metro Airport. The Michigan Department of Environmental Quality required the airport to move away any threatened or endangered plants and animals and create one-and-a-half acres of new wetlands for every one-acre impacted by the construction.
