AN Taisce has called for developers behind a proposed private hospital on the Dock Road to explore alternative city sites.
Developers behind the 92-bed scheme have sought a time extension to build the facility.
They are seeking full planning permission for the construction of a private hospital.
They have been forced to seek this because their previous licence to build at the Blackberry Park industrial area expired last year.
Under local authority rules, a developer has five years from when planning permission was given - in this case 2007 - to build.
The heritage group were invited to make a submission to the application.
They say although the application is for an extension of permission, it should be treated as a new idea.
They believe the proposal - which will see 257 car parking spaces - is unsustainable, and because the site is in an area where the floodplain of the Ballinacurra Creek has been infilled, the site is dependent on embankment protection.
An Taisce wants to see “alternative” city locations looked at.
They want “further evaluation” before county planners make a decision.
A final verdict on the proposals is expected to be delivered from County Hall in the next month.
Fine Gael councillor Richard Butler has previously welcomed the plans.
He said the proposed introduction of another private hospital in the city would offer consumers a welcome choice between Barrington’s Hospital, and the Mid-Western Regional.
The developer was not available for comment.
