Deputy council leader Marie Boulton has argued the planning application for the heritage centre at Rubislaw Quarry should come before the authority’s planning committee.
The Lower Deeside councillor described the proposal as a “significant project” for the city and said she has asked chief executive Angela Scott to ensure it is considered by councillors.
Under normal local authority policy, planning applications only have to be considered by committee if there are six or more objections.
It would be up to the committee convener, Ramsay Milne, and the head of planning, Margaret Bochel, to make that decision.
The Rubislaw Quarry heritage centre plans include a permanent museum, education suite, temporary exhibition and conference area, meeting rooms, a 60-table restaurant and terraced views over the quarry.
Mrs Boulton said: “I am not trying to determine what should or should not be approved, but this is a significant project and it should be coming for councillors to determine.
“I was surprised to hear that it was not going to come to committee.”
“I have asked for this to be looked into by the chief executive. If there are only three objections, I don’t think that should mean it is dealt with under delegated powers.
Hugh Black, a former managing director of a construction company and one of the owners of the site, has described the plans as “one of the most unique and strategic landmark projects the city has seen for many years.”
He said they would be “delighted” if the plans would be heard before the committee.
