City Hall planners are due to decide next week on planning permission for a new helipad at Cork University Hospital.
The application was lodged with City Hall in December, but planners requested more information, following complaints and submissions.
The application proposes the new helipad be constructed on the staff car park, at the northeast corner of the hospital grounds. The planning notice confirmed the development would include a two-storey staff car park to replace the 164 spaces lost as a result of the helipad.
The hospital has described the development as a critical piece of infrastructure.
There were objections from a number of residents in nearby estates, who were concerned about safety and noise. They said the helipad would injure the use and enjoyment of their homes and surrounding areas.
In January, planners in City Hall asked the HSE to supply further information on the development. They asked the HSE to confirm that the helipad would be used solely for the transfer of critically injured patients and the outbound transfer of organs, and if the take-off and landings would be on a 24-hour basis.
The HSE was also asked to provide details of noise-mitigation measures and an in-depth noise report, with special consideration given to the homes nearby.
CUH previously had a helipad, but it was closed when the emergency department was redeveloped in 2003.
In the case of emergencies since, helicopters have been landing at Cork Airport or Bishopstown GAA pitch, located just behind the hospital.
Almost 200 helicopter transfers have taken place between Bishopstown GAA pitch and Cork Airport and CUH in the past three years.
