This study seeks to identify potential sites for flood evacuation shelters in Austin, Texas. These Shelters will support public health interventions during persistent and long flooding periods. The state of Texas has experienced devastating flood events in the recent times that posed a high health risk to people, destroyed properties worth billions of dollars, and rendered more than a million residents homeless. Many Scholars have conducted studies using location-allocation models for siting evacuation shelters. This study gathers ideas from past studies to apply the concept to the city of Austin. Geographic information systems provide available tools to evaluate the level of exposure and vulnerability and to perform suitability analyses to find the most suitable locations for evacuation shelters. The result of this study will help urban planners, jurisdictional health department and stakeholders in decision-making efforts and in sustainability enhancement, land use development, and flood hazard mitigation and management.
