Final eight Port Hills properties zoned green
Christchurch Earthquake 2011
The final eight Port Hills properties have been green-zoned.
The white-zoned Lucas Ln properties were today officially announced as being in the green zone.
All eight properties are at risk of being hit by landslip, and wet weather over winter and continuing seismic activity has exacerbated the risk.
A work programme will remove almost 40,000 cubic metres of unstable land above the properties to make the area safe.
Canterbury Earthquake Recovery Minister Gerry Brownlee said this had been "identified as the most cost-effective and socially beneficial way to ensure the residents can move on with their lives".
"If this area was to become a red zone and the houses were subsequently removed, that would in turn create a landslip hazard for green-zone residents further down the hill and disrupt more lives," he said.
"Working with the owner of the unstable section of land, we will remove the slip hazard and remove the issue."
The time spent zoning the eight properties was because of monitoring how the landslip had behaved over time, he said.
Most of the Lucas Ln properties are subject to section 124 notices issued by the Christchurch City Council under the Building Act 2004. Once the landslip hazard is removed, these notices can also be removed.
Brownlee said the Lucas Ln option was not one that could be carried out individually by other homeowners, including those zoned red because of rockfall risk.
"Lucas Ln is a large-scale landslip issue and is completely different to the life-risk problems posed by rock roll in other parts of the Port Hills,'' he said.
''This solution will be the most effective, the fastest to implement and not cause any additional effects on other residents."
Mayor Bob Parker said the council and the Canterbury Earthquake Recovery Authority (Cera) had worked hard to establish the best option for what was "an unusual situation" in the Lucas Ln area.
"By the end of May next year, this hazard will have been removed and the owners of the homes directly threatened by it will be safe,'' he said.
"This is a unique problem that we have not encountered in other parts of the Port Hills, so the unique solution we have arrived at is quite appropriate."
Parker said the cost of moving the unstable land would be shared between Cera and the council, with the details yet to be worked out.
Today's announcement meant there were now over 181,000 residential properties zoned green and 7860 zoned red. Of those zoned red, 4903 have settled with the Crown and 6205 have signed a sale and purchase agreement.
Property owners in Lucas Ln will also have the opportunity to take part in the Port Hills zoning review and have until November 16 to lodge an application on cera.govt.nz.
