Land classified as green means that homes are suitable for repair and rebuild.
Key points to note
Land generally suitable for houses to be repaired or rebuilt;
Property owners should talk directly with their insurer or EQC about repairs;
Property owners no longer have to wait for the results of any area-wide land assessment reports by EQC or their engineering consultants Tonkin & Taylor;
There will be some isolated exceptions where geotechnical assessments will be required due to major land damage;
Repair and rebuilding work should take into consideration the risk of ongoing aftershocks, so some finishing tasks such as brick and driveway concrete laying should be delayed until that risk decreases.
What does Technical Category 2 (TC2, yellow) mean?
Some properties in the green zone have experienced liquefaction-related land damage and considerable settlement during the sequence of Canterbury earthquakes. While land in the green zone is still generally considered suitable for residential construction, houses in some areas will need more robust foundations or site foundation design where foundation repairs or rebuilding are required.
Technical Category 2 (TC2, yellow) means that minor to moderate land damage from liquefaction is possible in future significant earthquakes.
You can use standard timber piled foundations for houses with lightweight cladding and roofing and suspended timber floors or enhanced concrete foundations.
Detailed information about foundation requirements is available on the Ministry of Business, Innovation and Employment (MBIE) website.
