‘Wairarapa Districts Liquefaction Vulnerability Assessment’, Report for Carterton District Council by Tonkin & Taylor Ltd, December 2021, Job No. 1018016
To provide CDC, MDC and SWDC with a district-wide liquefaction vulnerability assessment to identify areas of land susceptible to liquefaction. The technical report and resulting map outputs will be used to inform a district plan change along with land use, subdivision and building consent applications.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>The available base information provides enough information for a Level A (basic desktop assessment) level of detail across the Study Area. The main factor controlling this level of detail is the spatial extent of the available geotechnical investigations and groundwater information across the Study Area. Further studies could be undertaken at higher levels of detail once additional information becomes available.</SPAN></SPAN></P></DIV></DIV></DIV>

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>T</SPAN><SPAN><SPAN>his assessment has been made at a broad scale across the three districts and is intended to approximately describe the typical range of liquefaction vulnerability across neighbourhood-sized areas. It is not intended to precisely describe liquefaction vulnerability at an individual property scale. This information is general in nature, and more detailed site-specific liquefaction assessment may be required for some purposes (e.g., for design of building foundations).</SPAN></SPAN></P><P STYLE="font-weight:bold;margin:10 0 10 0;"><SPAN><SPAN>A key consideration of the liquefaction vulnerability categorisation undertaken in accordance with the MBIE/MfE Guidelines (2017) is the degree of uncertainty in the assessment. Discussion about the key uncertainties in this assessment is provided in sections 3.2 and 3.3 of the associated liquefaction vulnerability report.</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV>
