Flood Risk Check
Know exactly how deep the water gets — not just whether it floods.
All sources are independent — a positive from one confirms or contradicts another
What This Report Checks
Every available flood dataset — queried simultaneously at your exact property coordinates.
Government Flood Planning Overlay
Whether council has formally classified this land under the NSW Government flood planning framework. The same data that appears on a Section 10.7 certificate.
Council Flood Model Depth
Where council has published detailed engineering flood models, we query the actual modelled water depth at your property — for every severity level from minor to catastrophic.
Flood Extent Mapping
Point-in-polygon check against council and state flood extent boundaries. Over 100 local government areas covered, with per-event severity where available.
Satellite Flood Detection
European Space Agency radar satellite imagery that sees through cloud cover, compared against a dry-season baseline. Detects recent standing water independent of any government dataset.
Long-term Surface Water History
Four decades of European and US satellite imagery analysed to calculate what percentage of time your property has had visible surface water.
River Gauge Flood History
The nearest Bureau of Meteorology river gauge — how far away, when it last recorded a major flood event, and the peak water height.
Ground Elevation
Terrain height above sea level from a high-resolution NSW Government elevation model. Flood depth is the difference between water level and ground elevation.
Emergency Service Activations
International emergency management activations that have mapped flood extent at this location. Confirms whether this property was inside a formally mapped flood event.

How It Works
Your address is resolved to precise coordinates, then queried against every available flood dataset simultaneously — NSW Government planning layers, council engineering flood models, European Space Agency radar satellites, Bureau of Meteorology river gauges, and international emergency management records. Where council has published flood model grids, we sample the actual raster cell at your property — giving you depth in metres, not just a binary yes or no.
Flood Data Summary
Check your property's statutory flood status and council flood study exposure. The NSW EPI statutory overlay check covers the full state.
Council flood model depths are available for select areas where councils have published engineering flood study data — coverage is expanding as new studies are released.
