Thousands of Michigan residents were affected by the flooding, with many unaware of their flood risk due to outdated or nonexistent FEMA maps. Homes, infrastructure, and personal belongings were severely damaged, and some residents were unable to secure flood insurance. The lack of accurate flood plain mapping leaves communities across the U.S. vulnerable, especially as climate change increases the likelihood of extreme weather. Experts warn that similar events could become more frequent, emphasizing the need for updated risk assessments and preparedness measures.
