Land-zoning information released
The Canterbury Earthquake Recovery Authority (Cera) has released the geotechnical data behind its land-zoning decisions on the flat land.
The information, which shows the mapping of ground cracking, liquefaction and lateral spread observations, and measurements of ground elevation, is available now on the Cera website.
The Government red-zoned 7354 residential flat-land properties based on the information.
The Earthquake Commission is providing some property owners with site-specific land-damage reports, which include more detail on land damage on their property.
Cera chief executive Roger Sutton said the geotechnical data could be released now the zoning review process was complete.
He said the information was ''quite technical'' and efforts had been made to simplify it so it could be easily understood.
"This data gives the wider picture of the different degrees of damage across Greater Christchurch," he said.
"It may help people understand why the damage on their land is considered feasible to address individually, as opposed to the residential red-zone areas which would have required more complicated area-wide remediation solutions."
A Cera spokeswoman said there would be no opportunities for residents to use the data to challenge their property's zoning or request a further review.
''The previous comment, 'This is it', still stands,'' she said.
The reports, collated using a range of data sources, including the EQC, were finalised today, the spokeswoman said.
