TRIM ref RDC-154258<\/SPAN><\/P>

Description that was added to the maps:<\/SPAN><\/P>

Zone A: Areas of volcanic-derived rocks and soils. Volcanic processes by their very <\/SPAN><\/P>

nature are high-energy. No soft ground is expected in zone A as the dominant <\/SPAN><\/P>

processes preclude the conditions necessary for its development. <\/SPAN><\/P>

Zone B: Huka Group sediments and Hinuera Formation. These sediments were formed in <\/SPAN><\/P>

a range of environments. Sediments with soft and very soft strengths at the time <\/SPAN><\/P>

of formation have consolidated over time and are now likely to meet the <\/SPAN><\/P>

requirements for being defined as good ground as per the draft New Zealand <\/SPAN><\/P>

Standard for timber framed buildings (DZ3604). <\/SPAN><\/P>

Zone C: Undifferentiated Holocene alluvium. Sites from a range of environmental <\/SPAN><\/P>

conditions are present within this zone. Small areas of soft to very soft ground <\/SPAN><\/P>

may be present as a surficial layer in some places. <\/SPAN><\/P>

Zone D: Sites of Holocene (last 10,000 years) swamp deposits and Holocene lake or delta <\/SPAN><\/P>

sediments between the 9000 ka and modern shorelines. Four of the five <\/SPAN><\/P>

documented sites of soft ground (Fitchett, 2007; Phillips, 2009; and Cowbourne <\/SPAN><\/P>

2009, 2010) are located at sites mapped as Zone D. <\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 2193, "latestWkid": 2193, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -4020900, "falseY": 1900, "xyUnits": 10000, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "", "parentLayer": { "id": 320, "name": "Ground Stability" }, "subLayers": [], "minScale": 0, "maxScale": 0, "referenceScale": 0.0, "drawingInfo": { "renderer": { "type": "uniqueValue", "field1": "DESCRIPTIO", "uniqueValueGroups": [ { "heading": "", "classes": [ { "label": "A: Areas of volcanic-derived rocks and soils.
