Flooding possible. Be prepared.

Flood alert

Be prepared.

Groundwater levels in East Surrey and South London have been rising throughout the winter following higher than average rainfall. Levels continued to increase through most of February and March in response to heavy rainfall and storm events. The Caterham Bourne between Woldingham and Purely is now flowing along its course. On 15 March 2024, the Environment Agency installed equipment to monitor the flow and levels on the Caterham Bourne in Kenley Bourne Park.

Properties with deep basements and low lying land in and around Purley and the Caterham Bourne may experience flooding. Riparian owners are reminded to keep clear the sections of river that flow through their land. Flooding of properties, gardens and low lying land elsewhere is not expected at this point in time.

The Environment Agency is monitoring the situation alongside Surrey County Council, Tandridge District Council and the London Borough of Croydon. We will update this message on Wednesday 27 March 2024, or sooner if the situation changes.
