How Eviron is zoned
Buying in Eviron? 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 14.28 km², Eviron is highly constrained by planning overlays. About 70% of the suburb sits within a mapped flood overlay, and 100% is flagged bushfire-prone. The dominant land-use zone is Primary Production. The median lot measures about 33,112 m² across 129 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.
