Research article: Household resilience to major slow kinetics floods: a prospective survey of the capacity to evacuate in high rise buildings in Paris

Abstract

<jats:p>Abstract. This article presents the results of a prospective survey of households living in the only high rise residential buildings of Paris, which are located in a flood zone. It questions the behavior of households likely to be subject to evacuation instructions in the event of a progressive flooding impacting the functioning of the technical networks and associated urban services. The survey received 523 responses from 11 residential high-rise buildings located in the 15th district of Paris. It assessed the propensity of households to evacuate autonomously through three main factors: the capacity to self-evacuate, to self-host and to go to this temporary accommodation. The survey answers explicit requests for information by local authorities on inhabitants' capacities to self-evacuate and to self-host in order to support the formers' estimation of shelter requirements. The typology of evacuation capacities reveals that most of the respondents are partially dependent due to difficulties relating to re-accommodation issues. Furthermore, many people seems to have an incorrect perception of the public authorities' responsibilities. Information and warning systems could thus be improved, notably through a participative method. </jats:p>

Review

“…670 The information provided in hazard awareness brochures and hazard awareness meetings is not necessarily limited to those who read the brochures or attend the meetings. Lindell et al (2015) found that more people knew they should evacuate immediately after a severe earthquake because it could cause a tsunami than had read haz-…”

“…or an expectation ("We don't expect that this person will create panic because people won't panic in response to this type of information."). If the authors intended this statement as an injunction, they are mistaken because panic is extremely rare even during life-threatening disastersâȂŤseeLindell et al (2006) Chapter 8. If the authors intended this statement as an expectation, they should restate it that way.716 As noted in my comments on line 546, there is relevant research on the relationship between expected and actual evacuation behavior.…”

“…They could be of an intrinsic nature and an extrinsic nature. In short, the ability or propensity depending mostly on their intrinsic factors (Rabemalanto et al, 2020) and the willingness of households to evacuate are the main characteristics that can facilitate or hinder their evacuation decisions. Because the significance of the influence of these factors on the households' decisions could vary depending on the context (Murray-Tuite & Wolshon, 2013), identifying households likely to evacuate can prove complex (Wright & Johnston, 2010).…”
