What the Environment Agency's rivers-and-sea flood-risk data says about Ashford Common

Ordnance Survey places 100 postcodes in Ashford Common in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 1,763 properties in the EA dataset's likelihood bands.

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.

Rivers and live river levels near Ashford Common

Environment Agency gauges within 10 km of Ashford Common watch River Thames, River Ash, River Colne, Wraysbury River, Chertsey Bourne.

The watercourse nearest Ashford Common

Two mapped watercourses are about the same distance from the middle of Ashford Common's at-risk postcodes: an unnamed stream (about 710 m) and an unnamed lake (about 870 m), so this page cannot say which one is nearer to you.

Distances along the river are from the point on each watercourse nearest the middle of Ashford Common's at-risk postcodes. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
