The Welsh Government’s ‘Rapid Assessment of Damages’ tool was developed to provide Risk Management Authorities (RMAs) with a proportionate approach for assessing flood damages for smaller scale investments in Wales.
The tool utilises a Wales national average house price to establish a capping value for flood damages, which improves equitability between different socio-economic groups.
For larger flood risk management schemes, the Welsh Government recommends that RMAs utilise the Middlesex University Flood Hazard Research Centre’s ‘Multi-coloured Manual and Handbook’ to assess flood damages. This method provides a greater degree of precision when estimating flood damages and allows for the consideration of local property values.
