Dublin City Council is implementing the Wad River Flood Alleviation Scheme with funding from the Office of Public Works. Phase 1 of the Scheme has been completed. Work on Phase 2 is ongoing and the next stage is planned to comprise works under the Howth Road and under Clontarf Promenade. Following those works the next stage is planned to consist of works along Collins Avenue East, Malahide Road and Collins Park. All of these remaining works are planned to be carried out over a number of years.
The total Scheme, which comprises of large drainage culverts, a large retention pond and flood flow control devices, will provide protection against an estimated current 100-Year fluvial flood for approximately 206 buildings, as well as reducing flood risk to Howth Road, Malahide Road, Collins Avenue East and many local roadways in the Wad River Catchment.
