A flood alert for groundwater flooding remains in place in south London and Surrey following heavy rainfall.

The flood alert covering large parts of south London and Surrey was first issued by the Environment Agency in March and currently remains in place.

The Environment Agency has advised that groundwater levels in the south London and Surrey area have been rising over the winter following “higher than average” rainfall continuing to rise in February and March.

Areas at risk from Groundwater flooding:

  • Bromley
  • Bexley
  • Greenwich
  • Lewisham
  • Caterham Bourne
  • Coulsdon Bourne
  • Teddington
  • Carshalton
  • Coulsdon
  • Kenley
  • Purley
  • South Croydon
  • Whyteleafe

The Caterham Bourne continues flowing in the Whyteleafe and Kenley area, and the Environment Agency is monitoring the levels and flow of the Bourne in Kenley Bourne Park.

The agency has warned that properties with deep basements and low lying land in and around Purley and the Caterham Bourne could potentially experience flooding.

Riparian owners are being advised to keep clear the sections of river that flow through their land.

Although flooding of properties, gardens and low lying land elsewhere is not expected.

The Environment Agency is currently continuing to monitor the situation alongside Surrey County Council, Tandridge District Council and the London Borough of Croydon, with further updates expected next week.
