How Round Mountain is zoned
Buying in Round Mountain? 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 10.78 km², Round Mountain is highly constrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. Of what is mapped, 100% is flagged bushfire-prone. There are 6 heritage-listed sites on record, and the dominant land-use zone is Deferred Matter. The median lot measures about 95,224 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.

Is Round Mountain flood-prone?

Tweed is the authority to check for flood mapping in this area. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Yes - around 100% of Round Mountain is mapped as bushfire-prone, compared with a Tweed average of 91%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.
