As we watched Irene skirt along the East Coast, it became very clear that many buildings in both coastal and inland communities could see serious flooding. Also of note was that evidently many owners do not have flood insurance.
Many may not know that regular homeowner’s insurance does not cover flooding. This was the reason for protracted legal cases on insurance reimbursement after Katrina. If a home was destroyed by water (flood), then private insurers did not have to reimburse for damages. If the owner had enough foresight to buy flood insurance—separately purchased through an insurance agent but backed by the US government’s National Flood Insurance Program (NFIP)—then they would be reimbursed. If the home was destroyed by wind, then private insurance would cover—but when a home was simply gone in an area that had both high wind and water, it was very difficult to say which destroyed it.
Homes and buildings in high-risk flood areas with mortgages from federally regulated or insured lenders are required to have flood insurance. But many homes that could flood in an exceptional event are not required to have flood insurance. Such homes are not within a FEMA defined “flood zone.”
Zones that begin with “A” or “V” are high-risk flood zones, and the purchase of flood insurance is federally mandated on loans secured by properties located in communities that participate in the National Flood Insurance Program. Zones “C,” “B,” and “X” have a lower risk of flooding, and the federal mandatory purchase requirements do not apply. “V” flood zones are on the coast and are subject to wind-driven water, i.e., waves. “A” zones are subject to a 1% or greater chance of flooding in any given year; in short, they are in the 100-year flood plain.
Since most people buy their homes with a mortgage, if they are not required to buy flood insurance they assume they do not need it. With water forced many miles inland and torrential rains, many Katrina property owners found out the hard way that they were not going to be reimbursed or only partially reimbursed for their loss.
Access to outside resources—in this case, insurance money—is a critical part of community resilience. In lower flood risk areas, NFIP-backed insurance can be as low as $129 a year. That seems like a very small amount to insure against the risk of total loss.
Resilient communities build public awareness of the risks they face and the potential losses—they do not rely on mortgage companies to tell them their risk. No doubt many without flood insurance wished they had known this as they watched Irene move up the coast.
