Certified Floodplain Manager (CFM) Practice Exam

A 100 Year Flood is commonly referred to as a Base Flood. Although it may seem logical to select "Zone AE" or "Zone A#" since they both contain the letter "A", these are actually just specific flood zones and do not accurately describe the frequency of the flood. "A Zones" is a broader term that can include different flood zones, not just specific to the 100 Year Flood. Therefore, the most accurate and commonly used term for 100 Year Flood would be Base Flood.
