Dáil Éireann Debate, Tuesday - 3 October 2023
267. Deputy Mark Ward asked the Minister for Public Expenditure, National Development Plan Delivery and Reform if there is any rationale for an area (details supplied) to be considered a flood risk; if recent reviews of the area have been carried out; and if he will make a statement on the matter.

Amharc ar fhreagraThe Catchment Flood Risk Assessment and Management Programme (CFRAM) was the largest ever flood risk study carried out in the State. It culminated with the launch, in 2018, of 29 flood risk management plans which proposed 118 new outline flood relief projects. These were in addition to the major projects already completed and the schemes that were ongoing at the time within the existing capital works programme of the Office of Public Works (OPW).
The Camac River, which runs adjacent to / through the area concerned was covered by the CFRAM Programme, and the flood mapping for the area is available on www.floodinfo.ie.
The flood maps currently available indicate that certain sections of the area in question are susceptible to some form of fluvial flooding in a Medium Probability flood event, which has approximately a 1-in-100 chance of occurring or being exceeded in any given year. This is also referred to as an Annual Exceedance Probability (AEP) of 1%. The wider area would also be vulnerable to pluvial flooding during this type of flood event.
The area is currently being assessed under the River Camac Flood Alleviation Scheme (FAS) as it lies within the catchment of the scheme and where more up to date flood information will become available. Dublin City Council and South Dublin County Council in partnership with the OPW, have commissioned the River Camac FAS to address flooding within the catchment of the Camac River. The River Camac FAS is being designed to protect properties from fluvial flooding in a Medium Probability flood event and will also make recommendations in regard to minimising the risk of pluvial flooding in a Medium Probability flood event.
