You should review the local and very very recent Ballycullen/Oldcourt Local Area Plan which focuses on this. The flooding can't really affected Stocking Wood - surely you mean Stocking Avenue? - as it is on a hill !?
Re Stocking Avenue, the road itself has been flooded at the bottom but nothing undriveable through (and un-noticed by some residents!).
The water actually flows down the hill underground, across under Woodstown and hits estates about 1-2km over ... believe-it-or-not! (They do get flooded and have made lengthy submissions under the LAP)
