Temperature extremes, both freezes and periods of <br /> excessive heat, impact communities with a larger population <br /> of older people to a greater extent than those with younger <br /> populations. According to the 2010 U.S. Census, 41,178 <br /> residents (29%) in Indian River County are over the age of <br /> 65 (http://quickfacts.census.gov/qfd/states/12/12061.htmi). <br /> Freezing conditions primarily affect agriculture and homeless <br /> indigents. When conditions are predicted to be below <br /> freezing, shelters are opened. A survey of the County's <br /> homeless population was conducted in 2013, indicating that <br /> there are approximately 837 homeless individuals within the <br /> County <br /> (http://www.dcf.state.fl.us/programs/homelessness/docs/201 <br /> 3Cou ncil Report.pdf). Inland communities away from the <br /> moderating influence of the ocean or the estuary are more <br /> vulnerable to temperature extremes as are areas with <br /> significant agricultural assets. During 2006-2010, about <br /> 2,000 U.S. residents died each year from weather-related <br /> causes of death. About 31% of these deaths were attributed <br /> to exposure to excessive natural heat, heat stroke, sun <br /> stroke, or all; 63% were attributed to exposure to excessive <br /> natural cold, hypothermia, or both; and the remaining 6% <br /> were attributed to floods, storms, or lightning. <br /> (,http://www,cdc.gov/nchs/data/nhsr/nhsr076,pdf). This <br /> number is greater than the number of deaths caused by <br /> hurricanes and tornadoes combined. <br /> Extreme temperatures, especially freezes, can have <br /> significant impacts on agricultural economics in a <br /> community. In 2007, Indian River County's value of <br /> agricultural products sold was $136 million <br /> (http://www.freshfromflorida.com/Divisions- <br /> Offices/Marketing-and-Development/Education/For- <br /> Researchers/Florida-Agriculture-Overview-and-Statistics). In <br /> 2008, 136,896 acres were designated for agricultural use. <br /> This represents over 51% of the unincorporated area of the <br /> county. More than 60,000 acres in Indian River County are <br /> devoted to citrus production. In 1997, the value of all farm <br /> lands and buildings in Indian River County was estimated to <br /> be $1,243,117 (University of Florida, 2001). <br /> Risk Assessment. At the time of publication, a risk <br /> assessment model for extreme temperatures was not <br /> available.
