How Chisholm is zoned
Buying in Chisholm? 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 6.33 km², Chisholm is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 43% is flagged bushfire-prone. The dominant land-use zone is General Residential. The median lot measures about 620 m² across 2,883 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.

Where can I see a flood map of Chisholm?
The schematic on this page is a Chisholm flood map: the mapped flood overlays drawn over the suburb's terrain and street grid.
