“Beach nourishment projects have become commonplace along the US East and Gulf Coasts. These projects have immediate environmental impacts through burial of nearshore habitat and increased turbidity during project placement.The cumulative environmental impacts of doing this repeatedly on the same beach while conducting projects from Maine to Texas is unknown. But, we should be concerned. ” —Robert S. Young, PhD, Director, Program for the Study of Developed Shorelines, Professor, Coastal Geology, Western Carolina University

Coastal geologist criticizes beach renourishment efforts; By Robert S. Young, PhD; The State (08-17-2016)
Rob Young, who heads the Program for the Study of Developed Shorelines at Western Carolina University, said the government is subsidizing coastal development with renourishment money – and that’s costing taxpayers. Communities across the country have spent millions of dollars renourishing beaches. Those efforts encourage people to rebuild after every major hurricane…

South Florida, Out of Beach, Wants to Buy Sand from the Bahamas, Slate (11-02-2017)
Miami-Dade County lost 170,000 cubic yards of sand during Hurricane Irma. It’s the latest blow to South Florida beaches in perennial decline. Nearly half the state’s coast—411 miles’ worth of beach—is considered “critically eroded.”

Replacing Miami’s beach sands costs millions. Here’s how Congress intends to make it cheaper; Miami Herald (10-24-2017)

Rethinking Living Shorelines, By Orrin H. Pilkey, Rob Young, Norma Longo, and Andy Coburn;Program for the Study of Developed Shorelines / Western Carolina University, March 1, 2012, Nicholas School of the Environment, Duke University
In response to the detrimental environmental impacts caused by traditional erosion control structures, environmental groups, state and federal resource management agencies, now advocate an approach known as “Living Shorelines”that embraces the use of natural habitat elements such as indigenous vegetation, to stabilize and protect eroding shorelines.
