Underwood flood map and flood risk
Underwood, Logan City Council · Queensland · based on 4,189 mapped addresses
Under 1% of mapped addresses in Underwood sit inside Queensland's potential floodplain overlay (QFAO), and none of the ten mapped historic floods (1974 to 2022) reached the sampled addresses. Those maps don't cover every region. Logan City Council also maps its own flood planning areas, and the address check includes them. Other mapped hazards: 4.2% in a bushfire-prone area. Every property differs, so check the exact address.
