A rather vague Tweet posted on June 1st by Cllr Alan Lavin:
Presumably, a planning application will be lodged once this display period has passed. It's a pity there's no elaboration on what exactly will be on show (architect's drawings, model, etc.), and indeed where it will be on show.
Edit: I've been told Fingal County Council have the option to go the Part 8 route as opposed to a standard planning application.
