Title: Final Report: Texas Flood Social Vulnerability Index
Author:
Comments: Texas Water Development Board (TWDB) and other agencies in Texas utilize Social Vulnerability Indices (SVIs) for a variety of flood risk management purposes including,but not limited to, flood planning and allocation of flood mitigation funding. There are twowidely available sources of SVIs: first, the Social Vulnerability Index (SoVI) from theHazards and Vulnerability Institute at the University of South Carolina; second, the SVIcreated by the Agency for Toxic Substances and Disease Registry at the Centers forDisease Control (CDC). Both are primarily used at the census tract scale and aredeveloped across the geographic domain of the United States. SoVI and SVI areagnostic to the type of hazard for which social vulnerability is being modeled. Althoughthese existing SVIs have a wide range of applicable uses, they are customized neitherfor flood hazard, nor for Texas.
Subject: The purpose of this research effort is to develop a flood-specific SVI (TX F-SVI) for Texas that considers and utilizes parameters applicable and relevant to providing information on social vulnerability to flooding. Certain social conditions influence a household’s ability to prepare for, mitigate against, respond to, and recover from flooding events. For example, some factors – people working at lower wage jobs, as well as those unable to work or underemployed, those who live in aging housing or with poor access to telecommunication infrastructure, and seniors and people with disabilities who face challenges evacuating – are underlying vulnerability factors that lead to differential outcomes when a flood event occurs. The TX F-SVI developed in this project specifically considers the characteristics of Texans in building a composite social vulnerability index for flooding. This research was financially supported by the Texas Water Development Board and conducted by an academic research team from the University of Texas at Austin and Princeton University.
