I have no recent information on changes to seabed levels in the areas referred to by the Deputy. He will, however, be aware that there has been accretion in the area since the building of the Bull Wall and this accretion has resulted in the formation of the Bull Island at Dollymount. The island has maintained its present length since 1902 but has continued to increase in width. It could be expected in such circumstances that the seabed levels would fall in this area as a consequence.
In the event that Dublin Corporation, or any other party, wishes to undertake any work on or impacting on the foreshore it will be necessary, under the Foreshore Acts, 1933-98, for it to obtain a foreshore lease, licence or permission as appropriate.
