Groundwater levels in East Surrey and South London have been rising throughout the winter following higher than average rainfall. Since mid-February, levels have increased rapidly in response to rainfall received during Storms Ciara and Dennis. We expect properties with deep basements in Dale Road and Godstone Road in Purley will start flooding imminently. However, due to the nature of groundwater flooding, other properties may also experience flooding too. The Caterham Bourne between Woldingham and Purley is now flowing but remains in channel and is not currently increasing flood risk. Further rainfall could cause groundwater levels to rise further. 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 by Tuesday 3 March, or sooner if the situation changes.
