What Does Horsham's Flood Risk Classification Mean?

0.1% of postcodes in Horsham 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 Low , with 0% 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.
