Cork City Council Boundary Extension 2019

On June 1, Cork City will grow to nearly five times its current size taking in areas including Douglas, Rochestown, Ballincollig, Blarney and Glanmire. As part of this planned expansion,  the population of the city will grow by 85,000 to 210,000. 

The increase in size of the City will allow Cork City Council to take a take a lead role in driving the growth of the city and metropolitan region – driving improvements in investment, public transport, infrastructure and housing.

Staff at  Cork City Council  are working with Cork County Council to ensure that the transition of public services  is as efficient and as seamless as possible. With time, a bigger Cork City will also provide us with scope to further improve and expand our services to the public.
