Continued population growth and development in exposed areas across Coastal Louisiana has created a new geography of hazards and disasters within the coastal zone. Increasing storm frequencies coupled with sea level rise will undoubtedly intensify the intersection between flood hazards and coastal residents. Accordingly, the baseline (inherent) capacity of places to adequately prepare for and rebound from disaster events will be negatively impacted. This paper summarizes the value of incorporating research‐based techniques into a non‐structural assessment of flood vulnerability within the Northshore Region of Louisiana. The exploratory nature of the methodology employed in this study was focused on determining the value of non‐structural measures of vulnerability in mitigation planning and the role of research in evidence‐based decision support for public officials. The outcome of the study highlighted new perspectives for measuring vulnerability within a policy environment, offering community officials a more robust understanding of the dynamic intersection of the physical threats, social vulnerability, and economic components of flood risk. This knowledge is currently being used by decision makers in the region to cultivate enhanced mitigation tactics that have traditionally been structurally focused. By incorporating the biophysical, economic, and social vulnerability into a qualitative “place” vulnerability matrix for the study area, the authors have been able to gain a more robust understanding of the flood risks across the region. By integrating this new understanding of risk into potential mitigation strategies, planning for risk reduction expenditures can more appropriately consider the drivers of place‐specific vulnerability.
