Researchers from the Texas A&M University (TAMU), Brown University, and University of California (UC) San Diego SRP Centers developed an online interactive dashboard, called the Toxics Mobility Vulnerability Index (TMVI). Their objective was to display how land use, such as green space or industrial land, interacts with extreme weather and sociodemographic characteristics to affect public health.

To build the TMVI data visualization, project partners integrated diverse datasets to determine a community's vulnerability to flooding, toxicant transfer, and health outcomes. The current dashboard presents and maps vulnerability scores for three different areas: San Diego County, California; Harris County, Texas; and the state of Rhode Island. In the future, the data process behind this tool can be modified and used for other visualizations of elements affecting human health in different locations to help community members make informed decisions to address environmental risks.

Technology The TMVI is an online data visualization dashboard that presents interactive maps and charts showing how land use, such as impervious surfaces and green space, affects people's exposure to harmful chemicals and community resilience and health.
Innovation Diverse city, local, and federal data were integrated with SRP center datasets to create a platform for community-level analysis of social vulnerability and health outcomes. The resulting interactive dashboard allows users to visualize potential exposure and health threats to their community. This tool was leveraged to communicate vulnerabilities related to COVID-19. It also has the potential for use in the context of climate change and remediation strategies, since it identifies specific factors that contribute to flood risk, allowing decision makers to identify solutions.
Contaminants and Media Multiple contaminants, extreme weather, disaster events, sociodemographic characteristics; stormwater runoff, water, soil.
