This project analyzes community resilience to flood/hurricane hazards using spatial analysis in a case study of coastal Charleston County focusing on the Hispanic community. Flooding caused by sea level rise will likely occur between 25 and 85 days per year in Charleston County, S.C. and other Southeast Atlantic areas by 2050. Risks induced by sea level rise will threaten the wellbeing of local communities, to which scholars of risk refer as their vulnerability. Social vulnerability is the characteristics of a person or group and their situation that influence their capacity to anticipate and resist the impact of a natural hazard. Thus, in order to create resilient communities, assessing local social vulnerability in particular of marginalized groups is key to the process. This paper will report the results of a structured questionnaire survey and participatory GIS. The survey will assess vulnerability factors, flood preparedness, and perceptions of risk of Hispanics compared to non-Hispanics living in the area. Participatory GIS will be used at a community-level using concept mapping and sketch mapping to count, rank, compare, and discuss spatial patterns, graphically demonstrating the link between place and culture to support effective public policy solutions. There is a considerable gap in the knowledge related to the increasing threats to the basic livelihood of Hispanic families due to flood/hurricanes. This study attempts to identify policies and programs that would contribute to closing the gap and improve community resilience.
