Repetitive Loss Areas Based on a printout from the Federal Emergency Management Agency dated August, 1998, La Porte has 55 repetitive loss properties. A repetitive loss property is defined as a property that two or more NFIP losses of at least $1,000 each have been paid since 1978. The City's repetitive loss properties are plotted in Appendix A. It can be seen that the repetitive losses occur in areas not always prone to coastal storm surge, or found in the floodplain. Because repetitive flooding accounts for approximately 33% of all flood insurance claims payments, a community that wants a CRS classification must prepare a repetitive loss plan. This Floodplain Management Plan will address damage to all repetitive loss areas, and it is being prepared in accordance with CRS guidance.
