Abstract:

The first full-scale use in the United States of imported aragonite sand for beach restoration was undertaken at Fisher Island, Florida, between December 1990 and April 1991. About 20,000 cy of existing rubble and sand were excavated from the project beach. Approximately 30,000 cy of aragonite fill were then barged from the Bahamas, placed by truck, and stabilized by seven rock structures designed to minimize fill losses and impacts to nearshore sea grass beds. Six-month monitoring results suggest that the project is performing as per predictions. No adverse impacts nor physical decay of the aragonite have been observed to date.
