National Flood Risk Assessment

The National Flood Risk Assessment was the first step towards developing Flood Risk Management Strategies and Local Flood Risk Management Plans. It significantly increased our understanding of the sources and impacts of flooding and enabled us to identify areas at the greatest risk to the impacts of flooding where further assessment and appraisal of flood risk management was required to develop plans for that area.

The National Flood Risk Assessment established 14  geographic areas for the purposes of flood risk management planning. These areas cross local authority boundaries, facilitating partnership working and more catchment based decision making. Within these, Potentially Vulnerable Areas were identified as the areas with the greatest risk to the impacts of flooding and where further assessment and appraisal should be carried out.
