What the Environment Agency's rivers-and-sea flood-risk data says about Stanstead Abbotts

Ordnance Survey places 26 postcodes in Stanstead Abbotts in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea).

This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.

From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist.
