Mr Brown,
the DAP development plan is over thirty years old. The area to the north of Malahide Golf course, and the green belt which was built on some fifteen to twenty years ago - Dal Riada etc is directly under the proposed appraoch path as far as I recall.
Part of the solution to the M50 would be the removal of the toll plaza which generates such lenghty delays daily.
Perhaps the real scam that you should be crowing about is the manner in which the County master plan was ignored when some of these housing estates in the green belt were approved.
