Geotechnical engineers Tonkin & Taylor have assessed and mapped residential land damage caused by the devastating Canterbury earthquakes of 2010 and 2011.
Residential GREEN ZONE Fact Sheet
The residential green zone is the 'go zone'. This means that generally there are no significant land issues in this area that prevent rebuilding based on current adopted seismic standards.
Residential Orange Zone Fact Sheet
The residential orange zone is effectively the 'hold zone'. Some of the land in this area has suffered new damage in the 13 June 2011 aftershocks and requires futher assessment.
Orange Zone Fact Sheet
Residential Red Zone Fact Sheet
Some land in the Christchurch City and Waikariri District areas has been so badly damaged by the earthquakes since 4 September 2010 it is unlikely it can be rebuilt on for a considerable period of time. Engineers have mapped these areas and categorised them as residential red zone.
Residential White Zone Fact Sheet
The residential white zone includes areas, including the Port Hills and the central business district, which are still being mapped or are not residential land.
Temporary Accommodation Service
This service is for Canterbury householders who need help finding temporary accommodation following the September 2010 or February 2011 Earth quakes.
