strong waves in a 300-foot danger zone, which is the area east <br /> of A1A. Beaches would be evacuated and residents living <br /> along the coastline would be urged to move at least 15 feet up <br /> to the highest floor of a well-constructed building. Modeling <br /> results from a tsunami triggered by a large Portugal <br /> earthquake suggest more significant tsunami impacts locally. <br /> Risk Assessment. At the time of publication, no specific data <br /> were available to determine the local potential loss associated <br /> with a tsunami incident in Indian River County. However, state <br /> facility losses due to a tsunami impact to Indian River County <br /> are estimated to be $22,422,125. The Tsunami Hazard Zone <br /> for Indian River County is identified as the area east of <br /> Highway A1A. There are no critical facilities (schools, fire <br /> rescue stations, government buildings, health care facilities, <br /> etc.) located within this area. <br /> Probability: Florida has directly experienced few destructive <br /> tsunami and rogue wave events since 1900, with only five <br /> small recorded occurrences. The probability of future tsunami <br /> and rogue wave events in Indian River County is low. <br /> 2. Technological Hazards <br /> a. Radiological Accidents— Hazard Identification <br /> While an actual release of radioactive material is extremely <br /> unlikely and the immediate threat to life extremely low, <br /> vulnerability to a nuclear plant disaster could consist of long- <br /> range health effects with temporary and permanent <br /> displacement of population from affected areas. The potential <br /> danger from an accident at a nuclear power plant is exposure <br /> to radiation. This exposure could come from the release of <br /> radioactive material from the plant into the environment, <br /> usually characterized by a plume (cloudlike) formation. The <br /> area the radioactive release may affect is determined by the <br /> amount released from the plant, wind direction and speed and <br /> weather conditions (e.g., rain), which would quickly drive the <br /> radioactive material into the ground, hence causing increased <br /> deposition of radionuclides. <br /> Thirty of the 67 counties in the State of Florida are involved in <br /> preparedness planning for a commercial nuclear power plant <br /> emergency. Emergency Planning Zones (EPZs) have been <br /> designated for each power plant to enhance planning efforts <br /> Indian River County Comprehensive Emergency Management Plan Basic Page 59 <br />
