SECTION 5: HAZARD PROFILESFIGURE 5.8: Critical Erosion Areas in Volusia CountySource: Florida Department of Environmental Protection, Division of Beaches and Coastal Systems5.8.4 Probability of Future OccurrencesThe probability of the continuing occurrence of coastal erosion in the coastal areas of Volusia County ishigh. Florida’s Bureau of Beaches and Coastal Systems estimates an average of a one foot loss annuallyfor Volusia County in stable or accretionary areas. The area between Ormond Beach and Daytona BeachShores are eroding at a rate between zero and 0.5 feet annually, according to a 2000 study. Northernareas of the county, including the North Peninsula State Recreation Area, lose between 0.5 and 1.5 feetannually. Areas south of the Ormond Beach to Daytona Beach Shores stretch have a lower expectederosion rate due to extensive armoring (e.g., beach walls and revetments). However, natural erosion isoccurring southward from South of Ponce de Leon Inlet. Loss rates are as high as 1.5 feet per year anddecrease heading in southerly direction.The damaging impacts of coastal erosion are lessened through continuous (and costly) beachnourishment and structural shoreline protection measures. However, it is likely that the impacts ofcoastal erosion will increase in severity due to future episodic storm events.Volusia County Multi-jurisdictional Local Mitigation StrategyFebruary 20105:43
