Post-Event Review Capability

The Post-Event Review Capability (PERC) methodology was created by Zurich Insurance to provide research and independent reviews of large flood events. It seeks to answer questions related to aspects of flood resilience, flood risk management and catastrophe intervention. It looks at what went well, as well as opportunities improvement, and results in a set of recommendations for the future.
