How Silverton is zoned
We don't yet hold the planning scheme zoning for Silverton, so this page can't show its zone mix. That is a gap in our data, not an absence of zoning - every lot in Silverton sits in a zone under the Unincorporated - Far West Area Local Environmental Plan, and Unincorporated - Far West Area is the authority to check it with. The other overlays on this page are unaffected.
Across its 1186.31 km², Silverton is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 100% is flagged bushfire-prone. The median lot measures about 993 m² across 1,125 parcels.
