What Does Maldon's Flood Risk Classification Mean?

The flood risk band for rivers and the sea is Very low , with 4.4% of homes in a Medium or High band. Unlike the Flood Zone, the band counts the defences that are actually in place, which is why the two can describe the same street differently and both be right.
Maldon is one of the places where they disagree most in England: a large share of its postcodes are in Flood Zone 3, yet few of its homes carry a Medium or High band.
