Natural Hazards - Model and Map Update

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

This consultation has concluded.

The Council has been updating models and planning maps, to show the possible extent of natural hazards on land in the Waimakariri District.

UPDATED MAPS AND MODELS ARE AVAILABLE TO BE VIEWED HERE.

These models and maps are updated every few years to provide the best possible information for landowners looking to buy, build or develop.

Hazard maps are used when processing resource consents, rezoning land, for project information memorandum and building consents, to ensure that the risk from natural hazards to people and buildings is assessed.

They are also referred to on land information memorandum (LIMs) for buyers and sellers of property. The maps will also inform new planning provisions as part of the District Plan Review, which is underway.

Hazard information being updated includes:

  • Flooding – from rainfall, coastal inundation and stop bank breach
  • Tsunami
  • Liquefaction
  • Fault lines.

The new information will improve understanding of the risks within the Waimakariri District. You may have a number of questions which may be answered through the FAQ document under the 'documents' tab to the right.

The maps have improved the predicted level of hazards in some areas, but worsened it in others. We recommend that you find some time to go online to look at the latest information and see how it affects your property.

UPDATED MAPS AND MODELS ARE AVAILABLE TO BE VIEWED HERE.

At this stage, the Council is still deciding how best to respond to the updated information, both in terms of reviewing planning rules, as well as considering how it will affect the community and its assets into the future. It will take some time to understand the full impacts of the updated information, and how the Council and the community is to best respond.

The next step in this process is through the District Plan Review which will be looking at how we should respond to this new info by setting future planning rules and restrictions, so any future development is done in as safe a way as possible. We will be back in touch to get your feedback on this in early-mid 2021.

    My property in Highgate subdivision shows flooding where it can't possibly flood as the section was built up before the house was built, way above the road. Also, the flood map is almost impossible for me to access the area shown as flooded as it is greyed out. I only see it in a flash that disappears when I enter my address. I expect that the map will be redone to comply with actual flooding instead of what is shown currently. Please advise when you propose to come and view the actual ground levels around my home and how I make this a private message that I can keep track of in my email. Thank you.

    Thanks for getting in touch. This is one of the areas we have excluded from the results (ie its greyed out) as the developer was unable to provide updated ground levels prior to the modelling work. So for all intents and purposes this area hasn’t been assessed for flooding under the new modelling. However the subdivision will have been assessed under the Resource Consent and designed to ensure there is no significant flooding on the properties

    Again, many thanks for contacting us.

    Is there a problem with the sand dune erosion at Waikuku beach or are they expected to recover over time to their original form?

    Jos asked 9 months ago

    Hi many thanks for your message.  Coastal erosion has not been identified as a long term issue for the District. The coastline is advancing with a small exception near the Ashley River mouth. The maps on Friday will show this.

    Again, many thanks for contacting us.

    In the letter received today (14 Sept) it states "The updated maps and additional information is available online at waimakariri.govt.nz/let's talk"...so waste my time coming here, only to find "UPDATED MAPS AND MODELS WILL BE AVAILABLE FROM THE 18th SEPTEMBER.". Thanks.
