About the project
Due to wet weather in July and August 2022, a slip occurred opposite 16 and 18 Woodhouse Avenue, Karori.
All soil, rocks and debris that slipped onto the road has been cleared and temporary concrete barriers established to enable the road to be opened for traffic, but the footpath is still currently closed.
To repair the slip damage, we will be installing some rock anchor stabilisation for the upper portion of the slope, as well as some sub-horizontal drains to relieve pore water pressure on the slip face.
We will also install an erosion protection mat and hydroseed for the low, less steep portion of the slope.
Traffic management
Construction will not occur before 7am or after 7pm.
The road will be down to one lane, controlled by traffic signals or manually as required.
We will do our best to mitigate any construction noise or dust during the construction period.
We will monitor traffic flows, particularly during the commuting peaks to minimise commuter impact.
