Multidimensional analysis is a governance-based public policy tool that considers multiple analysis variables to respond to disaster risks effectively. Although there are several examples in the international arena, no such guidance has been developed in Chile for the administration's disaster response. Existing public policies for disaster risk management in Chile, specifically those applied in the post-disaster stage, are designed to strengthen institutionality and develop programs and strategies focused on catastrophe management, shaping actions that aim to reduce vulnerability and handle recovery processes. What do we know about the effects of these policies in the regions? This research analyzes how the absence of instruments to assess these results prevents understanding the performance and effectiveness of the plans applied. Based on a multidimensional evaluation of the Nongu & eacute;n neighborhood in Concepci & oacute;n, Chile, a typical example of misguided public policies is characterized, explaining how illadvised interventions can exacerbate existing problems. This neighborhood continues to grow and develop in a flood risk zone, albeit aware of this condition, thanks to records dating back 100 years before urbanization began. It is concluded that the public response, based on unidirectional approach interventions that disregarded the inhabitants' problems, has increased vulnerability to risk and a recurrence of damaging disasters. A post-disaster assessment using a multidimensional perspective of the habitat would allow intervening areas with projects that give rise to future development processes.
