Southampton City Council has expressed objection to the revised plans for the runway expansion at Southampton Airport in Hampshire, the UK.

The airport authorities intend to lengthen the runway by 164m so that it could increase the number of flights operating from the airport and accommodate larger aircraft such as Airbus 320 and Boeing 737.

However, Planning and Rights of Way panel chair Lisa Mitchell expressed her dissatisfaction with the efforts to restrict the impact on climate change and noise levels.

Earlier, in January, the city council voted against the airport’s original plans.

Following this opposition, Southampton Airport amended the proposals.

Southampton City Council had to review it before the councillors of Eastleigh, where the airport is situated, could make a final decision on the amended plan.

Under the updated plan, the local authority can set a maximum limit on the decibel level and offer grants for insulation to the affected residents, according to the Local Democracy Reporting Service.

Southampton Airport managing director Steve Szalay had earlier expressed his concerns over the airport’s future if it was not allowed to extend the runway.

Airport Expansion Opposition group member Lyn Bryshaw said: “The economic benefits for Southampton and the region have been overstated and no evidence at all has been presented to suggest that the airport would go out of business without the extension.”

Business South chair Tim Hancock was quoted by the news agency as saying: “The business community supports the Southampton Airport runway application. The certainty of the planning permission is essential for the future.”

A decision on planning approval is due on 17 December.

Southampton Airport has witnessed an 89% drop in passenger numbers this year.
