What share of Booval is exposed to high riverine flood risk?
ClimateNest's hazard overlay maps 11.2% of Booval in high-risk zones for riverine flood, with a further 78.3% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
