Project Overview

Introductory Video

South Dublin County Council, in partnership with the Office of Public Works (OPW), is carrying out an important new project to manage flooding from the Whitechurch Stream in Rathfarnham.

Flood Alleviation measures were assessed as part of a larger project to manage flooding from the River Dodder under the OPW’s national Catchment Flood Risk Assessment and Management (CFRAM) project. A Flood Alleviation Scheme is now being progressed as part of OPW’s Flood Risk Management Plans to address flood risk in Ireland nationwide.

The Whitechurch Stream Flood Alleviation Scheme (FAS) project team is now in place and consultants (RPS) have been appointed to assist the Council.

The objective of this project is to upgrade the Whitechurch Stream to protect against flood events that happen once in 100 years (1% AEP flood event) by providing up to 275 metres of Flood Defences. The €2 million investment will protect over 170 properties including 150 homes and up to 20 businesses.
