Michigan's flood risk is characterized by a mix of flood, flash flood, and lakeshore flood events. Over the past 30 years, NOAA data shows 619 flood events, 540 flash flood events, and 121 lakeshore flood events, resulting in a total of 12 deaths.
Recent federal disaster declarations highlight the ongoing threat, with multiple declarations for severe storms, tornadoes, and flooding in August 2023. These events underscore the varied nature of flood risk across the state, impacting both inland communities and coastal areas along the Great Lakes.
National Flood Insurance Program data indicates that Zone A has the highest number of claims, with 7,796 claims totaling $85 million. However, Zone X, which includes X_SHADED and X_UNSHADED, has a higher average claim cost than Zone A, suggesting that flood damage can occur in areas not typically considered high-risk. The UNKNOWN zone also shows a significant number of claims, indicating that flood risk may not always be accurately identified.

Michigan has received 819 federal disaster declarations, including 156 flood and coastal storm declarations.
FEMA designates flood zones across Michigan using the following classifications:
AE High Risk — 1% annual chance of flooding (100-year floodplain). Insurance required for federal mortgages.
VE Very High Risk — Coastal flooding with wave action. Strictest building codes.
X (Shaded) Moderate Risk — 500-year floodplain. Insurance recommended.
X Low Risk — Outside major floodplains. Insurance optional but advisable — from 2014 to 2024, nearly one-third of NFIP claims came from outside high-risk zones.
Properties in Michigan FEMA-designated Special Flood Hazard Areas (zones A and V) with federally backed mortgages are required to carry flood insurance through the National Flood Insurance Program (NFIP).
The average NFIP premium in Michigan is approximately $809 per year. Rates vary significantly based on flood zone, building elevation, and coverage amount.
Even outside high-risk zones, flood insurance is recommended. From 2014 to 2024, nearly one-third of NFIP claims came from properties outside the high-risk Special Flood Hazard Area. Michigan residents can purchase flood insurance through the NFIP or private insurers.
