> “We had a 100-year flood last year. It will be 99 years before that happens again.” This is why I prefer the term “1% chance flood”. That 1% chance is there EVERY year. FEMA estimates that a person living in the 1% chance floodplain has a 24% chance of experiencing that flood within 30 years (average mortgage life).
