Flooding occurs when a watercourse is unable to convey the quantity of runoff flowing downstream. Surface water runoff on new development sites can be managed by reducing or delaying the discharge of rainfall to public sewers and watercourses. The risk of flooding can be minimized on and off site through sustainable drainage systems such as rainwater harvesting systems, soakaways, permeable paving or green roofs etc.
Building sites will be assessed whether they are located in a flood risk zone. For more information please call us on 020 8815 9977.
