A major gap in understanding community flood resilience is a lack of an empirically validated measure of it. To fill this gap, the Zurich Flood Resilience Alliance developed an approach to test and validate a measure of community flood resilience. The approach holistically measures a set of sources of community flood resilience and, when floods occur, it also measures resilient outcomes (level of loss and recovery time). The data is collected and assessed via a web and mobile based measurement tool. Here we report results from data collected in 118 communities across 9 countries using mixed method data collection approaches. This study represents the first large scale analysis of systemic and replicable flood resilience baseline data. The learnings from the analysis provide insights into sources of community flood resilience as a first step to building an evidence based approach to building effective flood resilience capacity.
