How Lilyvale is zoned
Buying in Lilyvale? 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 22.1 km², Lilyvale 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 are 5 heritage-listed sites on record, and the dominant land-use zone is National Parks and Nature Reserves. The median lot measures about 1,630 m² across 74 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.
