How Semaphore is zoned

Across its 1.24 km², Semaphore is highly constrained by planning overlays. About 23% of the suburb sits within a mapped flood overlay. There are 60 heritage-listed sites on record, and the dominant land-use zone is Established Neighbourhood. The median lot measures about 396 m² across 1,635 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.
