| Zone | Risk Level | Insurance Required? |
|---|---|---|
| A, AE, AH, AO | High risk (Special Flood Hazard Area) | Yes, with federal mortgage |
| V, VE | High risk, coastal | Yes, with federal mortgage |
| B, X (shaded) | Moderate risk | Recommended |
| C, X (unshaded) | Low risk | Optional |

After flooding events, monitor your utility's website and local news for boil water advisories.

Steps to reduce flood damage to your home:
- Install a sump pump with battery backup
- Elevate utilities (furnace, water heater, electrical panel) above potential flood levels
