The impacts of climate change – heat waves, drought, heavy rains, flooding and rising sea levels– are already being felt in communities across California and the United States. These impacts present new challenges for local governments who are working to build resilience. In order to prepare for climate impacts, it’s crucial for communities to understand how climate change will impact the health of their specific populations. This interactive story map illustrates a recent assessment conducted by the San Francisco Department of Public Health which summarizes how two connected climate impacts – flood inundation and extreme storms – may impact public health, with a specific focus on vulnerable communities. The final map in this series compiles all of the indicators into a flood vulnerability index, which the San Francisco Department of Public Health will use to inform climate and health programs and planning efforts going forward.
