Community Vulnerability Assessment Tool Methodology

Communities must identify exposure to hazard impacts to proactively address emergency response, disaster recovery, and hazard mitigation, and incorporate sustainable development practices into comprehensive planning. Hazard mitigation, an important part of sustainable development, eliminates or minimizes disaster-related damages and empowers communities to respond to and recover more quickly from disasters. The Community Vulnerability Assessment Tool (CVAT) is a risk and vulnerability assessment methodology designed by the National Oceanic and Atmospheric Administration’s Coastal Services Center to assist emergency managers and planners in their efforts to reduce hazard vulnerabilities through hazard mitigation, comprehensive land-use, and development planning. CVAT analysis results provide a baseline to prioritize mitigation measures and to evaluate the effectiveness of those measures over time. This methodology is flexible, as results may be achieved using a geographic information system or static maps with overlays and handwritten data. This paper outlines how to engage stakeholders and explains the CVAT process. Several case studies also highlight some of the challenges/problems and best practices/opportunities associated with applying the CVAT methodology.
