Castleconnell and the surrounding area was affected by flooding by the River Shannon in 2009 and 2015, following periods of prolonged rainfall. The OPW, working in partnership with Limerick City and County Council and other local authorities, commissioned and have completed the Shannon Upper and Lower River Basin (UoM 25/26) Catchment Flood Risk and Management (CFRAM) Study.
The CFRAM Study Area included Castleconnell as an AFA (Area for Further Assessment) and concluded that a Flood Relief Scheme would be viable and effective for the community.
Limerick City and County Council appointed JBA/JB Barry team in 2019 to assess, develop and design an appropriate, cost-effective and sustainable flood relief scheme which aims to minimise risk to the existing community, social amenity, environment and landscape.
