How Yengo is zoned
Buying in Yengo? 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 300.73 km², Yengo is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 100% is flagged bushfire-prone. There is 1 heritage-listed site on record, and the dominant land-use zone is National Parks and Nature Reserves. The median lot measures about 164,455 m² across 80 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.
