Project Overview

Project Update

In December 2020 (following the making of an application by the Council, on or about 29th July 2020, for approval under section 177AE of the Planning and Development Act 2000, as amended) An Bord Pleanála granted planning approval in respect of the Whitechurch Stream Flood Alleviation Scheme.

 

Subsequent to this grant of planning approval by the Board, an application for leave to apply for judicial review of the Board’s decision was made to the High Court in February 2021 by the Ballyboden Tidy Towns Group. The High Court granted the Ballyboden Tidy Towns Group leave to apply for judicial review. This judicial review of the Board’s decision to grant the planning approval is scheduled for hearing in November 2021. As the matter is the subject of those legal proceedings currently before the High Court, the Council will not be making further comment in respect of same.

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.

Forming part of the five main tributaries of the River Dodder, the 7.7km Whitechurch Stream rises between Tibradden and Kilmashogue Mountains. It flows northerly through Marley Park and St. Enda’s Park, onto Willbrook, where it meets the Owendoher River. Flowing through parkland and urban areas, the Whitechurch Stream includes a large number of bridges, culverts and weirs..
