Flood risk management
The new arrangements for securing sustainable drainage (SUDS) measures proposed as part of major developments were introduced by the government on 6 April 2015. As part of these changes, new ‘non¬ statutory’ national SUDS standards have been introduced and government planning policies have been strengthened to make clear that SUDS should be delivered in all new developments.
In line with Government requirements, the Council has produced a number of flood risk documents which provide information on all sources of flooding within the Borough. These contain flood risk maps which are being used by the Council to identify the need for flood alleviation schemes and to inform the preparation of Sutton’s Local Plan. Interactive food risk maps are also available on the Environment Agency (EA) website.
The London Borough of Sutton is a lead local flood authority (LLFA) under the Flood and Water Management Act 2010.
