Excellent progress is being made on the Te Awaparahi Bay reclamation, with a split hopper barge working to dump hardfill into the second phase of the project.
Hard fill material from our Gollan's Bay quarry is being taken by truck onto a barge, and from there the material is moved by excavator to a split hopper barge then dumped into the reclamation area.
This process is repeated at least 7 to 9 times a day, as part of the second stage of the reclamation project.
The first 10ha of the reclamation has already been completed, this is the second stage, creating an additional 6ha.
Testing of sediment being dredged at the Te Awaparahi Bay reclamation site has been carried out this week.
As part of our Environmental Monitoring and Management Plan for the dredging, we are testing the sediment being dredged and disposed to the offshore disposal ground.
Heron Construction’s backhoe dredge, the GPK, has been working to dredge the softer sediments under the reclamation. The GPK places the material into barges which are then transported by tugs to the offshore disposal ground.
The tests are taken to confirm the quality of the sediment, particularly the levels of different metals.
Native geckos have found a new home in Riccarton Bush as part of a Lyttelton Port Company project supported by the Department of Conservation.
Last month Dr Graham Ussher and his team from RMA Ecology safely captured Waitaha geckos from the Gollans Bay quarry and released them in Riccarton Bush.
The eastern part of the Gollans Bay quarry has not been quarried before, and is being used as part of LPC’s Te Awaparahi Bay Reclamation project, creating an expanded container terminal to keep up with shipping demands.
Some of the area is habitat for New Zealand native Waitaha gecko, and LPC recently gained a Wildlife permit from the Department of Conservation which sets out how the company must manage the effects on geckos.
The team aimed to catch all the geckos within the salvage area, which will include young lizards as well as adults which could be over 20 years old. The geckos have been released into tall native forest at Riccarton Bush. It is estimated over 80 have been released.
Riccarton Bush was chosen because it has 7.8 hectares of established forest surrounded by a state-of-the-art pest and mammal-proof fence that keeps out predators such as rats and cats.
Department of Conservation’s Community Ranger Rachel Brown says a similar release of geckos was done in 2012 as part of the Sumner Road recovery project.
“Those geckos have been regularly seen by visitors and the Riccarton Bush Trust Ranger, so it is fantastic to see more of these native creatures safely relocated.”
The new Sumner Road provides an opportunity for fantastic views of Lyttelton Port and the reclamation project.
The Christchurch City Council's two-and-a-half year project to reinstate Sumner Road connecting Lyttelton and Sumner has been completed, and is now open to traffic for the first time since the earthquakes.
Not only does the road reconnect the Lyttelton and Sumner communities, it offers incredible views of Port Operations, and in particular the Reclamation Project at Te Awaparahi Bay.

Last week LPC staff began preparation work for the safe capture and release of native New Zealand geckos from the Gollans Bay quarry.
The eastern part of the Gollans Bay quarry has not been quarried before, and some of the area is habitat for New Zealand native Waitaha gecko.
LPC recently gained a Wildlife permit from the Department of Conservation which sets out how we are to manage the effects on the geckos.
On Friday, LPC Enviromental Advisor Crystal Lenky and Project Director Jared Pettersson along with Dr Graham Ussher spent the day placing artificial habitats at key locations around the quarry.
The geckos and skinks will be attracted to these areas and make it easier for LPC staff to capture when the final salvage is underway in a few weeks, says Jared.
The quarry is being used to supply most of the fill for the Te Awaparahi Bay Reclamation. Click here to view the project page.
In preparation for the next stage of reclamation, starting mid-April, we recently re-opened our Gollans Bay Quarry.
The work for this stage will include quarrying in Gollans Bay, dredging part of the reclamation footprint, the land reclamation itself and the construction of a new wharf. Check out the project page here for more info.
Our quarry at Gollans Bay will provide most of the fill material, with less than five per cent being building demolition rubble.
This is the first time the quarry has been used since the Christchurch earthquakes in 2011. Most of the work will be regular blasting, earthworks and transport of material down to the reclamation.
HC&R, a joint venture between Heron Construction and C&R Developments, will undertake the works for LPC.
