Across its 2.91 km², Jacka is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 87% is flagged bushfire-prone. There are 123 heritage-listed sites on record, and the dominant land-use zone is Hills, Ridges and Buffer Areas. The median lot measures about 459 m² across 435 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.
