How Erowal Bay is zoned
Buying in Erowal Bay? 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 3.53 km², Erowal Bay 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, 89% is flagged bushfire-prone. The dominant land-use zone is National Parks and Nature Reserves. The median lot measures about 944 m² across 1,036 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 Erowal Bay flood-prone?
We don't yet hold flood mapping covering Erowal Bay, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. Shoalhaven 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 89% of Erowal Bay is mapped as bushfire-prone, compared with a Shoalhaven average of 90%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.
