District Plan Review consultation now closed.

Initial public consultation on key draft changes to the current Selwyn District Plan closed on Monday 8 October 2018. Thank you to everyone who let us know what they thought of the review so far.

What’s next?

Following this initial public consultation on the District Plan Review, the Council will consider all feedback and start developing detailed provisions for the Proposed District Plan. Please note that a summary report on the initial public consultation will be made available on Your Say Selwyn website at www.selwyn.govt.nz/districtplanreview.

It’s expected the Proposed District Plan will be notified in early 2020 for formal public consultation. The longer timeframe is due to the local government elections at the end of 2019 and ensuring the newly elected Council endorses the Proposed District Plan before it gets notified.


We want to know what you think about the draft changes which affect how geotechnical risk in the district, in particular liquefaction, active faults, slope instability (eg rockfall) and earthworks, is managed in the future District Plan. These draft changes have been endorsed by the Selwyn District Council for further development as part of its District Plan Review.

How can I have a say?

To give us your feedback on the draft changes , you can:

There will be many consultation opportunities for feedback at different stages of the District Plan Review and this is the first such opportunity. It’s expected that the new District Plan will be notified in early 2020 and be fully in place, subject to any Environment Court appeals, in March 2022.

Background

Selwyn district runs from the east coast south of Christchurch, northwest through to the Southern Alps, crossing the Canterbury Plains. The geology, natural hazards and geotechnical hazards of the district are varied. In total, there are 24 areas in the district which contain either known or suspected active faults and folds. The main active earthquake faults in the district are Greendale, Porters-Amberley, Torlesse and Esk, and Cheeseman. The Alpine Fault is located approximately 15 kilometres beyond the district’s boundary (to the northwest).

The liquefaction hazard across the district is reliant upon the ground materials, groundwater levels and shaking intensity during earthquakes. Overall, the risk of damage from liquefaction in most of the Selwyn district is low.

Management of geotechnical risk in the current District Plan

The Council advises any person requesting a property’s Land Information Memoranda (LIM) of any known natural hazard affecting land. For example, properties in Arthur’s Pass have rock fall potential listed on their LIMs.
