MEETING OF CLONDALKIN AREA COMMITTEE

Wednesday, November 18, 2020

QUESTION NO. 3

QUESTION: Councillor Eoin Ó Broin

"To ask the Chief Executive if the cause of the flooding that occurred near the Duck Ponds in Corkagh Park two weeks ago not dissipating quickly has been established and might same happen again?"

REPLY:

The lakes in question were completed in 2000 as part of a flood alleviation scheme to protect the downstream Clondalkin households from flooding. As such they were designed to retain water in periods of heavy rainfall and if necessary, overspill on the neighbouring park lands without damage to property. On receipt of the recent complaint of footpath flooding, the Drainage Operations Section removed the silted up non-return valve on the pond outlet and constructed a temporary weir downstream to prevent the lake emptying completely. There appears to be a change in the flow regime to the lakes and this present arrangement appears to be successfully dealing with this.
