FEMA NRI Expected Annual Loss Estimates <br />A hail NRI EAL score, and rating represent a community's relative level of expected building, population, <br />and agriculture loss each year due to hail when compared to the rest of the United States. The EAL score <br />is positively associated to a community’s risk; therefore, a higher EAL score results in a higher Risk Index <br />score. Table 4-115 outlines the hail EAL for Kittitas County. <br />Table 4-115. Hail Expected Annual Loss (FEMA National Risk Index) <br />Jurisdiction Population <br />Equivalence <br />Building <br />Value <br />Agriculture <br />Value <br />Total <br />Expected <br />Annual <br />Loss <br />Expected <br />Annual <br />Loss <br />Score <br />Rating <br />Kittitas County $2,473 $926 $7,775 $11,174 14.8 Very Low <br />Expected annual loss scores are calculated utilizing an equation that combines values for exposure, annualized frequency, and historic loss <br />ratios (Expected Annual Loss = Exposure x Annualized Frequency x Historic Loss Ratio). <br /> <br />A strong wind NRI EAL score, and rating represent a community's relative level of expected building, <br />population, and agriculture loss each year due to strong winds when compared to the rest of the United <br />States. The EAL score is positively associated to a community’s risk; therefore, a higher EAL score results <br />in a higher Risk Index score. Table 4-116 outlines the strong wind EAL for Kittitas County. <br />
