What Does Thornton (Wyre)'s Flood Risk Classification Mean?

71.8% of postcodes in Thornton (Wyre) sit in Flood Zone 3, the planning band for land with a 1% or greater annual chance of river flooding or 0.5% or greater of sea flooding — and the map that draws it deliberately ignores flood defences.

The flood risk band for rivers and the sea is Very low , with 0.6% 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.

Thornton (Wyre) 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.
