DP Liquefaction Management Zone (OpenData)

This entity describes whether or not the land is subject to District Plan provisions dealing with the likely risk that unconsolidated sediments will transform into a liquid like substance during earthquake shaking, resulting in settlement damage to the ground. Spatial intersection with this feature will determine whether a Geotechnical Engineer is required to further assess the liquefaction potential of a property. The source data was received from ECan and has been reviewed and edited by CCC planners as part of the District Plan Review. This data is not suitable for the generation of LIM comments due to its subjective nature and/or the probable inaccuracy of the geometries.It is spatially abstracted to an area.Entity Type: Concept
