What Does Sonning Common's Flood Risk Classification Mean?
0% of postcodes in Sonning Common 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 not mapped here, which means the national assessment finds no rivers-and-sea exposure for Sonning Common's homes rather than a low amount of it. That is a statement about rivers and the sea only: surface water flooding is not included, and it is the larger source nationally.
