The probability of future flood events based on magnitude and according to best available datais illustrated in Figure 5.10, which indicates those areas susceptible to the 1 percent annual chance flood(100-year floodplain); the 1 percent annual chance flood with wave action (100-year coastal floodplain);and the 0.2 percent annual chance flood (500-year floodplain). Further, as described in other hazardprofiles, it is highly likely that Volusia County will continue to experience inland and coastal floodingassociated with large tropical storms, hurricanes and storm surge events.Anticipated sea level rise will increase the probability and intensity of future tidal flooding. Rising sealevel over time will decrease the return period (increasing the frequency) of significant flood events. Forexample; sea level rise of 1 foot over a typical project analysis period (50 years) may cause a flood eventcurrently of annual probability 2 percent (50-year flood) to become an event of 10 percent annualprobability (10-year flood). This rise in sea level will increase the probability and intensity of tidalflooding events, and exacerbate the loss of coastal wetlands and erosion of sand beaches that act asprotective buffers against flood events.Volusia County Multi-jurisdictional Local Mitigation StrategyFebruary 20105:53
