Plan Change 47 - Natural Hazards

Share on Facebook Share on Twitter Share on Linkedin Email this link

We’re in the process of updating our District Plan and will be undertaking a plan change that addresses the risk from natural hazards. It’s called Plan Change 47 and has three distinct areas of focus: the Wellington Fault, Mangaroa Peatlands and areas of High Slope Hazards.

The proposed changes impact some properties in Upper Hutt and we want to give you a heads up about what's being proposed, ahead of a formal Plan Change in 2022.


The Wellington Fault

The Wellington Fault is currently shown in the District Plan as part of a 40m wide corridor. As a result of further investigation by GNS Science, the position of the Wellington Fault is now better understood and the location and extent has changed in some areas.

We are proposing to update the District Plan maps to identify the current understanding of the fault position. This would result in a plan change for the Wellington Fault and other natural hazards, with changes to the rules for development in these hazard prone areas.

Our interactive online map viewer where you can zoom in and see the existing position of the Wellington Fault Band, and the proposed Wellington Fault Overlay in relation to your property is available below.


Mangaroa Peatlands

We've identified the Mangaroa Peatlands as having poor ground conditions for new buildings due to settlement of the peat soils. This hazard was identified by Coffey Geotechnical Engineers and a copy of their report can be found in the Supporting Information section (note, this document is very large and will take a while to load depending on your internet connection).

This plan change will introduce rules for new subdivision or residential development within the Peat Overlay. It is important that new development is managed in this area to ensure that future buildings are designed in a manner to address the risks associated with settlement due to the poor ground conditions in the Peat Overlay.

You can access our interactive online map viewer below, where you can zoom in and see the position of the Peat Overlay in relation to a specific property.

The proposed plan change will not impact existing dwellings or buildings. Rather it is focused on ensuring the risk from the poor ground conditions does not increase as a result of future development. This means that new subdivisions and dwellings within the Peat Overlay would be required to go through the resource consent process to determine whether the risk as a result of the poor ground conditions is appropriately mitigated.


High Slope Hazard

We’ve identified the portions of the city that have a high slope hazard. New building platforms in this area have the potential to impact the stability of the hillside. This means that new building platforms for dwellings in this area will be required to go through the resource consent process to ensure that the stability of the hillside is not impacted by development.

This hazard was identified by Coffey Geotechnical Engineers. You'll find their report in the Supporting Information section (note, this document is very large and will take a while to load depending on your internet connection).

Next steps

We would like your feedback on the proposed hazards and the approach that we are undertaking to these hazards. You can view the indicative provisions in the Supporting Information section. It's important to note these are likely to change as a result of landowner feedback.

We are still in the initial stages of this process. Letters have been sent to the landowners impacted by either the Wellington Fault Overlay, or the Mangaroa Peatlands, to share more information but any proposed plan change will be publicly notified so that landowners and the wider community can have their say.

If you have any questions, would like more information on the proposal, or would like to give us feedback on what’s being proposed, please complete the feedback form below, call James Beban on 022 659 1996, or email planning@uhcc.govt.nz.

Alternatively, a hard copy of any comments or thoughts you may have can be delivered to the Council reception at:

838 – 842 Fergusson Drive, Upper Hutt

Feedback closes at 5pm, on Friday 29 October.
