80% of all disasters declared in the United States are caused by floods. To relate it better to home and business owners, many mortgages have a repayment period of 30 years. Buildings in areas that are in or are very close to a 100-year flood plain have a 26% chance of experiencing a flood during the life of the loan. However, during that same period, there is only a 4% chance of a fire.
In the past 20 years, most of the areas in the City affected by flooding are not in designated floodplain areas.
