Across its 6.89 km², Casula is moderately constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 19% is flagged bushfire-prone. There are 9 heritage-listed sites on record, and the dominant land-use zone is Low Density Residential. The median lot measures about 567 m² across 4,541 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.
