Liquefaction and/or Lateral Movement of Ground

Implications for Building Consents

New knowledge regarding seismic risk for the Waimakariri District means that, as of 19 May 2011, foundations within an area where liquefaction and/or lateral spread could occur are now subject to specific engineering design by a chartered professional engineer except those of AS/NZS1170 importance level 1 (e.g. structures with a total floor area <30 m², farm buildings, isolated structures, towers in rural situations, fences, masts, walls, in-ground swimming pools).
