Massachusetts’ Plum Island now has artificial dunes supported by geotextile bags. The dunes have been installed to protect structures on the island after considerable erosion. Officials have even installed fences to protect the dunes. Members of the Plum Island Taxpayers Association (PITA) are anticipating that the US Army Corps of Engineers will approve a plan to dredge the Merrimack River and deposit the lionshare of dredged sand on Plum Island for beach renourishment.
