Yes. Homeowners can often purchase flood insurance outside a Special Flood Hazard Area. A lower-risk map designation does not mean floodingis impossible or that ordinary homeowners insurance will cover the loss.

- Flash flooding

- Coastal storms
- Development-related drainage changes
- Areas where mapping is incomplete
- Extreme events exceeding mapped assumptions
Is coverage less expensive outside a high-risk zone?
It may be, but pricing depends on current rating methodsand property-specific information. Obtain an actual quote.
What should owners investigate?
Ask:
- Which flood sources affect the area?
- Has the property or street flooded before?
- Are there drainage or grading concerns?
- Is coverage available through NFIPand private carriers?
- What are the waiting periods?
- Are contents included?
- Are temporary living costs covered?
- Does the policy cover mudflow as defined?
