Giving Cork City Council control over the approximate area bounded in dark green on the map would be the most sensible solution, if the option to expand the city council area is chosen rather than the option to merge the two councils into one.There was another proposal some time back to bring the entire Cork Metro region under a single authority......
If boundary expansion is the preferred plan then they should be ambitious and make the entire metro area one city region under Cork City Council. Dublins four local authorities need to likewise be merged into a new Dublin metro authority. The trend in England and the continent is for city regions, Ireland should do likewise.
It might even encourage a similar solution for Dublin which should really have one council (with boroughs in a 'federal' arrangement) for the entire built-up area of greater Dublin, to include Bray and Greystones, plus some suburbs and towns in Kildare and Meath, even if that upsets those for whom county boundaries are sacrosant.
I'm not sure I understand the Irish loyalty to county boundaries which were imposed by the English, albeit with some boundaries being based on pre-Norman political units. If it wasn't for the organisation of the GAA on county lines I suppose these loyalties wouldn't be anywhere near as strong as they are today. That's not a dig at the GAA which was only responding to counties which had been created centuries earlier.
