<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Data created as part of GNS report 2010/81.</SPAN></P><P><SPAN>TRIM ref RDC-154258</SPAN></P><P><SPAN>Description that was added to the maps:</SPAN></P><P><SPAN>Zone A: Areas of volcanic-derived rocks and soils. Volcanic processes by their very </SPAN></P><P><SPAN>nature are high-energy. No soft ground is expected in zone A as the dominant </SPAN></P><P><SPAN>processes preclude the conditions necessary for its development. </SPAN></P><P><SPAN>Zone B: Huka Group sediments and Hinuera Formation. These sediments were formed in </SPAN></P><P><SPAN>a range of environments. Sediments with soft and very soft strengths at the time </SPAN></P><P><SPAN>of formation have consolidated over time and are now likely to meet the </SPAN></P><P><SPAN>requirements for being defined as good ground as per the draft New Zealand </SPAN></P><P><SPAN>Standard for timber framed buildings (DZ3604). </SPAN></P><P><SPAN>Zone C: Undifferentiated Holocene alluvium. Sites from a range of environmental </SPAN></P><P><SPAN>conditions are present within this zone. Small areas of soft to very soft ground </SPAN></P><P><SPAN>may be present as a surficial layer in some places. </SPAN></P><P><SPAN>Zone D: Sites of Holocene (last 10,000 years) swamp deposits and Holocene lake or delta </SPAN></P><P><SPAN>sediments between the 9000 ka and modern shorelines. Four of the five </SPAN></P><P><SPAN>documented sites of soft ground (Fitchett, 2007; Phillips, 2009; and Cowbourne </SPAN></P><P><SPAN>2009, 2010) are located at sites mapped as Zone D. </SPAN></P></DIV></DIV></DIV> |
