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
