communities located on both the Indian and Sebastian rivers. Vulnerability in the rest of the County is low to very low, with the exception of specific locations along some drainage canals. The Department of Public Works has identified the following areas as being in need of beach nourishment projects: • Sectors 1 & 2 — R-4 to R-17; • Sector 3 — R-20 to R-55; • Sector 5 — R-74 to R-86; and, • Sector 7 — R-97 to R-107. Risk Assessment. FDEP updated a statewide assessment of beach erosion in 2014. In that assessment, FDEP defined the "critical erosion area" as a segment of shoreline where natural processes or human activity have caused or contributed to erosion and recession of the beach or dune system to such a degree that upland development, recreation interests, wildlife habitat, or important cultural resources are threatened or lost. There are three critical erosion areas (15.7 miles) in Indian River County. The northern 9.5 miles (R1 -R51.3) south of Sebastian Inlet is critically eroded threatening State Road AIA, Sebastian Inlet State Park facilities, the McLarty Treasure Museum, and private development along Ambersand Beach, Sanderling, Summerplace, and Wabasso Beach. The museum has a rock revetment, and inlet sand transfer is conducted south of the inlet. A beach restoration project has been constructed at Ambersand Beach. The northern 3.1 miles of Vero Beach (R70 -R86) is critically eroded with development and recreational interests being threatened. Much of this area has seawalls, dune restoration, and small dune nourishment projects, although a major beach restoration has not yet been designed. In southern Indian River County a 3.1 -mile segment (R99 - R115.7) is critically eroded threatening development interests. A beach restoration project has been constructed along a portion of this area (FDEP 2010). Droughts — Hazard Identification. Drought is a normal, recurrent feature of climate, although many perceive it as a rare and random event. In fact, each year some part of the U.S. has severe or extreme drought.
