EA publishes guidance on natural flood management heat maps
The Environment Agency (EA) has published guidance on its natural flood management (NFM) heat maps, which are intended to help identify potential project opportunities under the flood and coastal erosion risk management investment programme. The guidance explains how to access the heat maps, outlines the methodology used to develop them and sets out how they should be used. The maps are available via the Department for Environment, Food and Rural Affairs’ Data Services Platform and are based on the EA’s simplified national-scale methodology for estimating the benefits of NFM. The guidance notes that the maps do not take account of local features such as pumped catchments, washlands, large reservoirs, roads or other local infrastructure. Users are therefore expected to apply local knowledge to determine whether proposed measures are likely to operate effectively in the relevant context. The EA plans to refine the maps over time, including by screening out areas where NFM would be unlikely to be effective due to local features and by incorporating local NFM opportunity mapping.
