How Cardiff Heights is zoned
Buying in Cardiff Heights? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 1.17 km², Cardiff Heights is highly constrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. Of what is mapped, 68% is flagged bushfire-prone. The dominant land-use zone is Low Density Residential. The median lot measures about 756 m² across 489 parcels. These figures are suburb-wide - the overlays that actually apply to a given lot can differ block to block, which is what a property-level check tells you.

Is Cardiff Heights flood-prone?
