High means FEMA returned an address-coordinate flood hazard zone. Medium means FEMA returned official panel or jurisdiction context but not an exact zone polygon. Low means the lookup needs a standardized address or the FEMA service was unavailable.
No result is legal, engineering, lending, insurance, appraisal, or emergency advice. Local floodplain administrators, FEMA, insurers, lenders, and licensed professionals control final decisions.
