SECTION 4: RISK ASSESSMENT
Repetitive Loss Analysis A repetitive loss property is a property for which two or more flood insurance claims of more than $1,000 have been paid by the NFIP within any 10-year period since 1978. An analysis of repetitive loss was completed to examine repetitive losses within the region. According to August 2018 NFIP records, there are a total of 118 repetitive loss properties within Wake County, of which 49 are insured and 69 are uninsured. At the time of their first claim, 35 of these properties were non-residential and 83 were residential. There are 27 properties on the list classified as severe repetitive loss properties. A severe repetitive loss property is classified as such if it has four or more separate claim payments of more than $5,000 each (including building and contents payments) or two or more separate claim payments (building only) where the total of the payments exceeds the current value of the property. Table 4.41 summarizes repetitive loss properties by jurisdiction as identified by FEMA through the NFIP. Table 4.41 – Repetitive Loss Properties by Jurisdiction

Environment
During a flood event, chemicals and other hazardous substances may end up contaminating local water bodies. Flooding kills animals and in general disrupts the ecosystem. Snakes and insects may also make their way to the flooded areas. Floods can also cause significant erosion, which can alter streambanks and deposit sediment, changing the flow of streams and rivers and potentially reducing the drainage capacity of those waterbodies. Consequence Analysis
Table 4.42 summarizes the potential detrimental consequences of flood.
