At the request of Dublin City Council the Office of Public Works has carried out some emergency works since the severe flood. There was a danger of subsidence at three houses off Tolka Road following the failure of a protecting wall and Office of Public Works was requested to place rock, approximately 30 metres in length along the exposed bank of to stop further erosion. To secure this, a concrete wall, similar to the original wall, is now being built along this stretch. Rock has also been placed in the bed of the channel to prevent scouring of the new wall. A number of trees that were obstructing the flow of water in this area were also removed. This work is due to be completed in the next few weeks.
DCC has also undertaken some emergency works by installing temporary flood defences in the Griffith Park area. It has also undertaken a programme of gully cleaning in the areas affected.
As the Deputy will be aware, DCC agreed to include a detailed study of the River Tolka in the greater Dublin strategic drainage study at the request of the Office of Public Works. The study is being funded by the Office of Public Works and is expected to be completed in May 2003. The consultants have been requested to produce an interim report on what immediate measures can be taken to alleviate flooding in the areas worst affected in the past few weeks. This interim report has just been received and is being considered by officials of the city council and Office of Public Works. I am not in a position to say at this stage what the outcome of this will be.
