How Cottage Point is zoned
Buying in Cottage Point? 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 0.4 km², Cottage Point is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 99% is flagged bushfire-prone. There are 3 heritage-listed sites on record, and the dominant land-use zone is National Parks and Nature Reserves. The median lot measures about 878 m² across 82 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.
