Extreme precipitation events, coastal storms, and fluctuating water levels pose threats to Lake Michigan coastal communities. Flooding, erosion, and storm surge can threaten properties and impair infrastructure and other assets that are vital to the region’s economic security. Agricultural and urban runoff during heavy rain events can also impair water quality in receiving water bodies, further threatening recreation and tourism. Planning, preparing for and adapting to these and other climate change hazards can enhance community resilience and strengthen coastal economies.
