Stage 1 – Scheme Development

  • Assess potential options for achieving a scheme to provide flood relief to the areas at risk of flooding from the River Lee downstream of Inniscarra Dam.
  • Design of a flood forecasting system for Cork City and the lower reaches of the River Lee (downstream of Inniscarra) to facilitate decision-making on dam discharges and, if necessary, the erection of temporary / demountable defences downstream and in Cork City.
  • Assessment and development of a scheme to permit greater discharges from the Inniscarra Dam without causing flooding of properties, and to provide protection along the Lower Lee and through Cork City against residual fluvial flooding and flooding from tidal sources.
  • Carrying out a Constraints Study to identify the key environmental issues in the study area, which may be impacted upon by possible flood alleviation measures, and/or which may impose constraints on the viability and/or design of one or more measures.
  • Preparation of an initial Appropriate Assessment Screening Statement.
  • Public consultation, including public information days. The purpose of the first public information day will be to seek initial views from the public and other interested parties in relation to the key issues that the study should address, and to highlight points of local importance to inform the design of potential flood alleviation measures. The purpose of the second public information day will be to gather views of the public about the preferred scheme option in advance of the formal exhibition stage.

Stage 2 – Public Exhibition

  • Public Exhibition of the scheme in accordance with the requirements of the Arterial Drainage Acts, where the public’s view of the proposals will be ascertained.
  • Consideration of observations received from the public and the making of possible amendments to the scheme.
  • Preparation of an Environmental Impact Statement (EIS) for the scheme.

Stage 3 – Detailed Design, Confirmation and Tender

  • Undertaking the detailed design of the final preferred scheme.
  • Confirmation of the scheme by the Minister for Public Expenditure & Reform.
  • Preparation of contract documents and undertaking the procurement of a works contractor to construct the scheme.

Stages 4 and 5 – Construction and Handover of the Works

  • Supervision of the works.
  • Supervision of the contracts.
  • Handover of the completed works.
