Carrick On Shannon Flood Relief Scheme

Leitrim County Council and the OPW are progressing a flood relief scheme for Carrick on Shannon and Cortober and the required studies for adjacent upstream and downstream areas.

Carrick on Shannon and Cortober are prone to flooding. Both the N4 National Primary Road and the R280 Regional Road are subject to flooding during flood events including the area behind the Landmark Hotel off the N4. Properties adjacent to the quay area in Carrick on Shannon and Cortober in Roscommon, plus properties along the R280, are also subject to flooding during flood events. Recent significant flood events include those in 2009 and 2015. Minor flooding occurred most recently in February 2020.

This project involves the assessment and development of a flood relief scheme (a ’Scheme’) and other measures to manage the existing flood risk in Carrick on Shannon and Cortober, and also the potential for significant increases in this risk due to climate change, ongoing development and other pressures that may arise in the future.

A steering group was established for the project in February 2020. The Steering Group is chaired by Leitrim County Council. Other members of the group included OPW, Roscommon County Council and Ryan Hanley. Ryan Hanley will provide the engineering and environmental consultancy services for the current project.

The initial stage of the project involves hydrological and environmental assessments, in addition to the outline design of flood relief measures, and cost benefit analysis.

Once a preferred flood relief option for the scheme has been determined and an outline design completed, Leitrim County Council will seek consent for the proposed scheme in accordance with the provisions of the Planning and Development Act. Once planning permission has been obtained, the scheme will progress through detailed design. Once detailed design has been completed, the scheme will proceed to tender and construction phase.
