Is Branch County, MI in a flood zone?
FEMA's National Risk Index puts Branch County's flood hazard at the 60.9th percentile nationally — below the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 100 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Branch County
Homes with a federally backed mortgage inside Branch County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 8.1% of them do — 62 active policies against 762 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Branch County, not just the ones FEMA mandates, 0.4% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
