The Whitechurch Stream has been identified under the Dodder CFRAM project as being liable to flooding during a one in one-hundred year flood event. This is mainly due to low banks, overtopping of existing defences or insufficient floodplain capacity. In addition, there is insufficient capacity at a number of bridges and culverts and this is causing water to back-up and producing increased water levels upstream.
The most recent flooding took place in 2011 and previously in 2007.
