Certified Floodplain Manager (CFM) Practice Exam

The feature depicted above the 500-year flood level on FIRMs is the C Zone. The C Zone represents an area outside of the 100-year floodplain, but with at least a 1% chance of flooding in any given year. This means that while the risk of flooding may be lower than in other zones, it is still present and property owners should take necessary precautions. The other options, A Zone, V Zone, and Unshaded Zone X, represent areas with higher risk of flooding and are therefore incorrect.
