Slope instability mapping was generated in general accordance with the Australian Geomechanics Society Guidelines for Landslide Risk Management (2007a).The mapping was undertaken over 2021-2025, and identifies areas that could be susceptible to slope instability. Four categories of slope instability and run-out susceptibility are shown:<ul><li>Tier I (areas of known active instability with previous slope failures impacting residential properties)</li><li>Tier II (areas identified as having elevated susceptibility to slope instability)</li><li>Tier III (areas identified as susceptible to slope instability) </li><li>Run-out zones (areas where debris from upslope instability may run out into)</li></ul> The mapping was commissioned by Nelson City Council and undertaken by Beca Limited. •    The Slope Instability Overlay was prepared from a desktop study, which did not involve field studies or site-specific assessments. •    The mapping is based on current knowledge and datasets available at the time.  •    The mapping is intended to be used at a consistent or smaller scale to the mapped scale of 1:5,000.  •    Mapping is indicative of potential slope instability susceptibility and debris runout affecting an individual site or property. It is not a replacement for site-specific assessments.  •    The accuracy of the mapping is limited by the manual process by which mapping was completed, the scale at which mapping was conducted, and accuracy of the input datasets considered in the assessment. •    The reports and mapping identify potential susceptibility, they do not include information on likelihood or consequence of a hazard occurring. •    The reports do not take into account the potential impact of climate change, which may exacerbate slope instability hazard. 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
