FEMA NRI Expected Annual Loss Estimates <br />A wildfire NRI EAL score, and rating represent a community's relative level of expected building, <br />population, and agriculture loss each year due to wildfires when compared to the rest of the United States. <br />The EAL score is positively associated to a community’s risk; therefore, a higher EAL score results in a <br />higher Risk Index score. Table 4-146 outlines the wildfire EAL for Kittitas County. <br />
