Well-Adapted UK floods workstream

Aims and Objectives The CCC require an update of the flood risk and adaptation analysis carried out in CCRA3. We require a supplier to carry out quantitative modelling to provide a robust and comparable evidence base to our previous assessment. The commissioned update should be constructed in a way that it can be linked to the separate CCC commission of a vulnerability dataset, which includes a flood vulnerability index. The commissioned analysis should: • Update CCRA3 flood risk analysis with the most recent input data on present day risk (e.g. from the 2024 National Flood Risk Assessment NaFRA2 for England). • Test the investment requirement to maintain present-day risk, using a range of adaptation measures within the current flood defence portfolio. • Assess the optimum level of investment for flood risk reduction.
