Repairs to Fripp Island The project objective was to rework and rebuild 2,400 linear feet of the FIPSD’s existing stone revetment on the north end of Fripp Island. This work was in response to shoreline damage suffered by Hurricane Matthew in 2016 and consisted of placing approximately 6,000 tons of new armor stone along the revetment in the tidal zone.
