Sawyer Street, St. George Island


The Apalachicola National Estuarine Research Reserve and the U.S. Environmental Protection Agency collaborated on this shoreline stabilization experiment using a breakwater on St. George Island in 1984. This project involved the development of an offshore breakwater, assessment of changes along the shoreline, creation and monitoring of a salt marsh, and public education and outreach.

Technical Details

Limerock/dolomite materials were constructed into a 150x6 ft breakwater (with one 6 ft gap) approximately 20 ft waterward of the mean high water line. Spartina alterniflora was planted just landward of the breakwater into several rows with each plant being about 2 ft apart.


Primary coordination and funding for this project was through the Apalachicola National Estuarine Research Reserve in association with the U.S. Environmental Protection Agency’s Near Coastal Waters Program.
