Post-flood policies and compensation regimes tend to focus on the resilience of public spaces and improving the adaptive capacity of future private property developments. This article focuses on the instruments associated with the resilience of existing privately owned residential buildings from the perspective of post-flood policies and compensation regimes. By reviewing the relevant legal and policy landscapes it aims to provide mutual lessons learned between the EU, its member states and the US and to set forth generally applicable recommendations for improving post-flood policies for existing buildings.

Examples of post-flood measures associated with the mitigation strategy are adaptive building requirements, resilient reinstatement efforts and green infrastructure, whereas the prime measure of the recovery strategy relates to financially compensating people following the occurrence of a flood event, be it through public ex post compensation schemes or insurance mechanisms (Suykens, Priest, Doorn-Hoekveld, Thuillier, & van Rijswick, 2016). Such schemes and mechanisms within the recovery strategy can and should have an important positive impact on strategies such as mitigation and prevention.The analysis is guided by the research question, What are the legal and policy requirements applicable to existing buildings after a flood event has occurred in the US and the EU, taking England and the Netherlands as examples? The following structure guides our findings. We set the scene by shedding light on the institutional DNA of the relevant countries and the EU. We then analyze the differences in flood risk management approaches in the US and the EU, the Netherlands and England. We then delve into post-flood policies specifically, and scrutinize the main key barriers in the recovery-mitigation nexus for all countries studied. Finally, we offer country-specific recommendations and more general conclusions on resilient post-flood policies.The article takes a legal research approach; more specifically, it contains a legal comparison. The comparison is a combination of dogmatic and functional approaches (Gorlé, Bourgeois, & Bocken, 1991). The dogmatic aspects relate to the in-depth analysis of primary and secondary legal sources (legislation of national governments, decentralized legislation, guidance and policy documents, case law) and a comprehensive overview of the legal system of the studied jurisdictions. The functional aspects regard the notion that a legal institution s...
