Name: Eastern Canterbury liquefaction vulnerability categories (2012)

Display Field: SOURCECODE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset outlines liquefaction zones as defined in Figure 2.1 of Brackley (comp), 2012, Review of liquefaction hazard information in eastern Canterbury, including Christchurch City and parts of Selwyn, Waimakariri and Hurunui Districts. Environment Canterbury report R12/83.There are two zones: Damaging Liquefaction Unlikely and Liquefaction Assessment Needed. The zones exclude those areas already classified into Technical Categoriesby the Department of Building and Housing (now Ministry of Business, Innovation and Employment).The zones are primarily for use by territorial authorities to help them decide whether a separate geotechnical assessment relating to liquefaction will be needed for development, and for subdivision and building permits to be granted.
