Item Information

snippet: To provide BOPRC with a region-wide liquefaction vulnerability assessment to identify areas of land susceptible to liquefaction as required in the Regional Policy Statement (RPS). The technical report and resulting map outputs will be used to inform land use, subdivision and building consent applications. In particular the vulnerability assessment outputs will be utilised by stake holders to inform the risk assessment requirements for liquefaction prone land

The Study Area also includes </SPAN></P><P><SPAN /></P><P><SPAN>two areas outside of the regional boundary, that being a small area to the </SPAN></P><P><SPAN /></P><P><SPAN>west of Mamaku and a large area south of Lake Rotorua to incorporate all of </SPAN></P><P><SPAN /></P><P><SPAN>the Rotorua Lakes Council Territory.</SPAN></P><P><SPAN /></P><P><SPAN>Intended RMA planning </SPAN></P><P><SPAN /></P><P><SPAN>and consenting purposes</SPAN></P><P><SPAN /></P><P><SPAN>To provide BOPRC with a region-wide liquefaction vulnerability assessment to</SPAN></P><P><SPAN /></P><P><SPAN>identify areas of land susceptible to liquefaction as required in the Regional </SPAN></P><P><SPAN /></P><P><SPAN>Policy Statement (RPS).

The main </SPAN></P><P><SPAN /></P><P><SPAN>factor controlling this level of detail is the spatial extent of the available </SPAN></P><P><SPAN /></P><P><SPAN>geotechnical investigations and groundwater information across the Study </SPAN></P><P><SPAN /></P><P><SPAN>Area. There are some small areas (e.g. parts of Whakatāne and Rotorua) </SPAN></P><P><SPAN /></P><P><SPAN>where higher levels of detail could be supported by the available base </SPAN></P><P><SPAN /></P><P><SPAN>information. Undertaking these studies at a higher level of detail is outside of </SPAN></P><P><SPAN /></P><P><SPAN>the scope of work for this project. </SPAN></P><P><SPAN /></P><P><SPAN>Other notes This assessment has been made at a broad scale across the entire region and </SPAN></P><P><SPAN /></P><P><SPAN>is intended to approximately describe the typical range of liquefaction </SPAN></P><P><SPAN /></P><P><SPAN>vulnerability across neighbourhood-sized areas. It is not intended to precisely </SPAN></P><P><SPAN /></P><P><SPAN>describe liquefaction vulnerability at individual property scale. This </SPAN></P><P><SPAN /></P><P><SPAN>information is general in nature, and more detailed site-specific liquefaction </SPAN></P><P><SPAN /></P><P><SPAN>assessment may be required for some purposes (e.g. for design of building </SPAN></P><P><SPAN /></P><P><SPAN>foundations).</SPAN></P><P><SPAN /></P><P><SPAN>A key consideration of the liquefaction vulnerability categorisation </SPAN></P><P><SPAN /></P><P><SPAN>undertaken in accordance with the MBIE/MfE Guidelines (2017) is the degree </SPAN></P><P><SPAN /></P><P><SPAN>of uncertainty in the assessment. Discussion about the key uncertainties in </SPAN></P><P><SPAN /></P><P><SPAN>this assessment is provided in sections 3.3 and 3.4 of this report.</SPAN></P></DIV></DIV></DIV>
