A hearing before independent commissioners Trevor Shiels and Christine Kelly was adjourned on the fourth day yesterday and is due to resume on August 25.
The commissioners heard a recommendation from legal counsel Amanda Dewar that the Corporation team, including herself, chief executive Steve Sanderson and project manager Mike Davies will meet Porter Group Ltd co-directors Alastair and John Porter and counsel Dr Royden Somerville in Christchurch on August 14.
The outcome of that meeting would then be submitted to the commissioners when the hearing reconvenes in Queenstown.
Mr Shiels said while there were other submitters who sought conditions to the construction of the airport's proposed runway end safety area (Resa), Remarkables Park Ltd's (RPL's) issues were the most significant.
Dr Somerville said clients RPL and Shotover Park Ltd (SPL), subsidiaries of Porter Group, wanted the future formation of the paper eastern access road guaranteed in case delays pushed the Resa's completion beyond the deadline of October 2011.
The access road would link Glenda Dr and Hawthorne Dr and simultaneously service the ongoing Remarkables and Shotover residential and commercial developments and help spread the load of projected traffic increases on State Highway 6.
A 16m wide bench for the access road across the fill was provided in the Resa proposal.
However, earlier this week traffic consultant Tony Penny, speaking for the Parks, recommended a minimum width of 22m to handle the daily 10,000 vehicles predicted to use the access road by 2021.
Lakes Environmental's consent engineer Sandra King, landscape architect Dr Marion Read and planner Wendy Rolls attended the four-day hearing.
Ms King said she believed conditions existed to mitigate noise and dust from haulage trucks using Tuckers Beach Road while working on the fill construction, but they may not be to the satisfaction of residents who submitted their concerns.
The eastern access road should be future-proofed by being made at least 22m and Queenstown Lakes District Council needed to be involved in the design, she said.
Dr Read said she was concerned about about the visual impacts of the completed extension on the natural western bank of the Shotover River.
She said she would prefer to see a road tunnel built into the fill to mitigate the effects and hide traffic headlights.
Mr Sanderson later told the Otago Daily Times the Resa would cost an estimated $10m to build and a ventilated road tunnel through the fill would add an extra $5m to $6m, which was prohibitive.
Ms Rolls said it would be useful if conditions mitigated the view of the fill construction, as contractors would be on site for 16-27 months.
Conditions should include an attempt to screen the finished access road from public view, she said.
