The map displays the most up-to-date data directly from the Environment Agency in relation to the main river network, flood zones 2 and 3, areas of historic flooding, areas at risk of surface water flooding, areas which are identified for flood risk management, and areas where natural processes could be used to reduce flood risk.

The map also includes the spatial extent of flood zone 3b (the functional floodplain) which has been defined by the Council in conjunction with the Environment Agency as part of the SFRA. The full SFRA report is available on the Council's website.

Users of this map should also check the Environment Agency's Flood Map for Planning.

Please note that as of 28 January 2025 the EA has published its new Risk of Flooding from Surface Water maps.

The Government Guidance advises that a minor development includes the development of an existing dwellinghouse, or development within the curtilage of a dwellinghouse, for any purpose incidental to the enjoyment of the dwellinghouse.
