Shaded areas are FEMA’s mapped flood hazard zones in and around Calhoun County, Alabama. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
Flash flooding from severe weather and slow-moving thunderstorms dominates the flood history of Calhoun County, supported by 32 recorded flash flood events out of 42 total flood-related occurrences in the last 30 years, alongside impacts from tropical systems.
Recent events illustrate this pattern. In June 2022, slow-moving and training thunderstorms driven by upper-level disturbances dropped heavy rainfall over North Central Alabama. Another significant event unfolded in March 2025, bringing severe weather, tornadoes, and isolated flooding to Central Alabama.
National Flood Insurance Program records indicate that property owners in both high-risk and moderate-to-low-risk areas experience claims. Zone A accounts for 83 claims with an average water depth of 4 inches and an average payout of $8,982, while Zone X records 21 claims with an average water depth of 6 inches and an average payout of $19,060. Homeowners in mapped high-risk zones, as well as those in Zone X and unmapped areas with a history of property claims and standing water, should pay the closest attention to flood risk.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Calhoun County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
