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 />
