How Jimna is zoned
We don't yet hold the planning scheme zoning for Jimna, so this page can't show its zone mix. That is a gap in our data, not an absence of zoning - every lot in Jimna sits in a zone under the Somerset Regional planning scheme, and Somerset Regional is the authority to check it with. The other overlays on this page are unaffected.
