328. To ask the Minister for Public Expenditure and Reform if the Office of Public Works will provide information on the pedestrian and railway bridge at Lansdowne Road in terms of the development of new flood defences along the River Dodder; if the height of the bridge was considered in these plans in terms of contributing to past flooding; and the way this is to be addressed in the current defence works.

The design of the River Dodder Flood Relief scheme has been undertaken by Dublin City Council, with the works being undertaken by the Office of Public Work's (OPW) direct labour force. The scheme was designed to provide protection against a flood event with an annual exceedance probability of 0.5%, commonly referred to as the 1-in-200 year event, which is the standard level of protection for locations that are tidally influenced. It is the OPW's understanding that the river was modelled with the bridge in place, and that it was determined that it does not contribute to flooding in the event of the design flood nor is it affected by such an event. The OPW understands, therefore, that the Council has no proposals to undertake work to the bridge.
