Transport corridors - Zoning issues

There are several zoning-related issues to consider:

Zoning may avoid the need to designate existing networks. However, a plan change would generally be required for any new routes or additions to existing routes not already included in the zone.
The merits of using zoning instead of a designation need to be carefully considered. For example, if transport corridors are zoned, a plan change would be required to widen the corridor (or extend the zone boundary). An alteration to a designation may create more certainty in such circumstances.
Land that is designated usually has an underlying zoning that applies to non-designated activities (eg, residential) and would revert to this if the designation is removed. Usually the zoning is consistent with the zones adjoining the designation. However, if a special zone is created for the transport corridor, a plan change would be required to allow the land to be used for another purpose.
Any activity proposed within a designation that was not part of the designation requires the agreement of the designating authority before proceeding. Depending on the district plan provisions, such an activity would be assessed in terms of the underlying zoning or, if applicable, the 'transport ' zone.
