Four to seven million cubic yards of sand and sediment will be needed to restore the damaged marshes at Prime Hook National Wildlife Refuge.
That’s the word from state research scientist Robert Scarborough who outlined a detailed assessment of what must be done to restore two wetland areas that have not kept up with sea-level rise.
The assessment came during the Partnership for the Delaware Estuary’s Environmental Summit in Cape May, New Jersey.
The Wilmington News Journal reports that state and federal officials say the cost of repairing the marshes and fixing the breaches in the sand dunes could run $20 million in the wake of Hurricane Sandy.
