Minister for Housing, Planning, Community and Local Government Simon Coveney has announced plans for the retention of two local authorities in Cork, but a significant expansion of the Cork City boundary.
It will the first expansion of the city boundary in 50 years.
The new plans come two years after a super merger of the two councils in Cork was rejected, following the Smiddy Report .
Minister Coveney asked for a new expert report, headed up by the former chief planner for Scotland, Jim Mackinnion.
The new plan would see areas such as Cork Aiport and Business Park, Ballincollig and Little Island becoming part of the city.
Upon completion, Cork City will have a population of 225,000 people, while Cork county will have 320,000.
This will make Cork Co Council the largest local authority in the country.
Mr Coveney plans to bring a memo to Cabinet with two weeks.
The changing of the boundary will have to be passed by Dáil Éireann.
Cork Co Council will be compensated for the loss of revenue.
Fianna Fáil leader Micheal Martin said the new plan made complete sense for both the city and county and would allow for sustainable growth in the years to come.
