For decades the City of Toledo, Ohio has been adversely impacted by persistent annual flooding. Widespread damages to homes, business, and public infrastructure coupled with local economic decline has driven city officials to begin searching for alternative ways to mitigate flooding. In 2012, the City of Toledo, NOAA, ASFPM, ERG, and USACE partnered together to evaluate is green infrastructure would be a cost-effective solution. The Toledo Flood Hazard Visualizer was developed to communicate the results of this study. With this tool, users are able to visualize how climate change and green infrastructure could impact flood damages on the property level.
