This project explores some of the determining features of effective and rapid decision-making processes in post-disaster resilience projects. It aims to examine how established theory on public decision-making can be applied in two post-disaster resilience projects and whether this theory is relevant in varying contexts based on the logic of realist explanation. The cases analyzed in this study are the post-disaster resilience projects in the neighborhood Roombeek in Enschede (Netherlands) after it was largely destroyed by the explosion of a firework depot and the Hudson River Project in Hoboken, New Jersey (USA) after Hurricane Sandy led to severe flooding of the city. The lessons about public decision-making processes that can be learned from studying Roombeek and Hoboken can provide beneficial insights for the future of the Hudson River project and other similar projects. Mechanisms observed in both contexts might also apply to similar projects in the future and help public administrators to increase the effectiveness and efficiency of decision making processes.
