New Zealand is subject to a range of natural hazards. These include natural events such as earthquakes, river flooding, coastal erosion and coastal inundation. These events create natural hazards when they affect people, property and the environment.
One of Nelson City Council’s responsibilities is to manage risk from natural hazards. Council is required by law not only to investigate natural hazards, but to make the relevant research available to anyone who is affected or interested.
Council fulfils this function in various ways, including:
- the Nelson Resource Management Plan
- building consents
- placing statements on property files noting that a property is potentially affected by a natural hazard (LIM and PIM)
- managing infrastructure assets
- civil defence responsibilities
Council has undertaken various technical studies to better understand where particular natural hazards may occur. This includes research and modelling for potential fault hazard, liquefaction hazard and flood hazard. Further information on each of these hazards is provided below.
Council is in the process of undertaking technical studies in relation to coastal erosion, coastal inundation and slope stability. More information will become available on this page as this work is completed.
Information regarding tsunami, including Tsunami Evacuation Maps and frequently asked questions, is held on the Nelson Tasman Civil Defence Emergency Management (CDEM) website.
Council’s natural hazards work will be used to inform the development of the Whakamahere Whakatū Nelson Plan (Nelson Plan) which is currently being prepared and will replace the Nelson Regional Policy Statement, the Nelson Resource Management Plan, and the Nelson Air Quality Plan.
Flooding, Fault and Liquefaction Hazards: Community Feedback 1 April – 16 June
The feedback period has now closed and Council has started collating the feedback received. We would like to thank the community for the time and effort given to engaging on this important subject with us. We had great attendance at our public information sessions. Natural hazards are an issue New Zealand is coming to terms with and the information the community gave us was of much value.
