Honest About Consensus that Climate future storms will Change be bigger 1. Vision: We Look Forward Not Backward 1. Vision: It Is More Important To Protect People Than To Sell Real Estate 1. Vision: Provide Equity and Transparency What is the Hurricane Harvey Registry? • Collaboration aimed at examining the long-term impact of Hurricane Harvey through a brief survey on housing, personal and environmental health • Hurricane Harvey Registry website also includes list of relevant recovery based resources Who should complete the Registry’s survey? • Any adult in the Harvey-impacted, area • Whether Harvey impacted you severely, lightly , or not at all it is important to share your Harvey HarveyRegistry.rice.edu experiences with the Registry Why should you participate in the Registry? • Research will help shape public health solutions by informing community members and stakeholders • Registry will enable data-driven preparation for future weather events Plan For Houston’s Resilient Future
