NOTE: The Office of Public Works through the Arterial Drainage Acts has submitted the proposal for the Glashaboy Flood Relief Scheme to the Minister for Public Expenditure and Reform for formal Confirmation. In May 2020, the Office of Public Works received correspondence from the Department of Public Expenditure and Reform that an independent assessment has been conducted and, pursuant to section 7(B) sub-section 4 of the 2019 European Union (Environmental Impact Assessment) (Arterial Drainage) Regulations, certain items of further information are requested to complete the process.

The additional information requested generally relates to further detail on the processes followed and assessments undertaken in developing the scheme. The additional information has been submitted to the Department in order that the assessment can be completed and the scheme confirmed by the Minister for Public Expenditure and Reform. This information was provided to the Department at the end of October 2020. Following a review period in November and December 2020 the Minister for Public Expenditure and Reform confirmed the Glashaboy River (Glanmire/Sallybrook) Drainage Scheme on the 18th of January 2021.

The programme for the appointment of a Contractor for this scheme is currently being updated to reflect confirmation.

The scheme will be funded from within the allocated €1 billion for flood risk management over the period 2018 – 2027. Provision for the cost of the Scheme is included in the Office of Public Works' multi annual capital allocation.

The Key Public Consultation Dates were as follows:

Public Consultation Day No. 1:

26th February 2014

Public Consultation Day No. 2:

Emerging Preferred Option

20th February 2015

Public Consultation Day No. 3:

Statutory Exhibition of Scheme

November - December 2016

The main elements of each stage are described below:

Stage 1 – Scheme Development

  1. Assess and develop a viable, cost-effective and sustainable Scheme, to allow the design flood event along the Glashaboy River and its tributaries without causing flooding of properties, in so doing protecting against flooding from pluvial, fluvial, tidal and surge.
  2. 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 design and viability of these measures.
  3. Preparation of the Appropriate Assessment Screening Statement
  4. Public consultation, including Public Information Days. The purpose of the first Public Information Day will be to gather information from the public about their experiences of flooding in the Study Area along with their thoughts on possible solutions to the flooding problem and their preferences in this regard.

Stage 2 – Public Exhibition

  1. 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.
  2. Consideration of observations received from the public and the making of possible amendments to the Scheme.
  3. Preparation of Environmental Impact Statement (EIS) for the Scheme.

Stage 3 – Detailed Design, Confirmation and Tender

  1. Undertaking the detailed design of the final preferred scheme.
  2. Confirmation of the Scheme by the Minister for Public Expenditure & Reform.
  3. Preparation of Contract Documents and undertaking the procurement of a Works Contractor to construct the Scheme.

Stages 4 & 5 – Construction and Handover of the Works
