A report prepared by Aer Rianta for the Department of Defence in 1992, entitled Review of Planning Policy In the Environs of Casement Aerodrome, Baldonnel, for Department of Defence, referred to a draft protected area order pursuant to section 36 of the Defence Act 1954. The report goes on to say that:
Following consultation with the Department of Transport and Power and the Planning Department of Dublin County Council, and on receipt of an undertaking from the Dublin Planning Office in June 1957, it was agreed by the Department of Defence that the promulgation of the Protected Area Order was not necessary at that time. The undertaking received was that Dublin County Council Planning Department would consult with the Department of Defence before a decision was made in relation to any proposed development which conflicted with the terms of the Draft Order.
This arrangement, which was designed to ensure the safety of air trafficen route to and from Casement Aerodrome, has operated satisfactorily down the years and, accordingly, it has not been necessary to introduce a protection area order as provided for at section 36 of the Defence Act 1954.
