New maps show which parts of Wales are most at risk of flooding and costal erosion. Natural Resources Wales (NRW) has launched an update to its online flood mapping service. The last upgrade was carried out in 2020 and the new information aims to provide better flood risk data as extreme weather events become more frequent due to the climate emergency. This latest improvement has added additional coastal erosion risk data.
The flood risk elements in the mapping tool are already widely used by the risk assessment industry, risk management authorities, Welsh Government, academics and the general public to help protect over 240,000 properties that are at risk of flooding in Wales - which is one in every seven properties in Cymru.
The map takes the risk of flooding from rivers, surface water, the sea and smaller watercourses categorised into locations of high, medium and low areas of risk. It also displays extra information such as flood defence locations and the local flood risk reduction benefits they bring.
