The Welsh Government has launched its national strategy for flood and coastal erosion risk management – https://gov.wales/national-strategy-flood-and-coastal-erosion-risk-management-wales. It sets out long-term policies to manage flooding – as well as the measures that will be taken over the next decade by organisations like Natural Resources Wales, local authorities and water companies to improve how the country plans, prepares and adapts to climate change over the coming century.
Fresh guidance in the shape of an updated Technical Advice Note 15 is promised by 2021. Part of the new approach is the Wales Flood Map, also just launched – https://naturalresources.wales/evidence-and-data/maps/long-term-flood-risk/?lang=en. This is designed to bring all Welsh flood and coastal risk mapping in one place, starting with the new Flood Risk Assessment for Wales (FRAW). The FRAW maps will be updated every six months so that people can see how flood schemes have reduced risk.
