Clare County Council applied to An Bord Pleanála under the provisions of Section 177AE of the Planning and Development Act, 2000 (as amended) for a flood alleviation project at Mortyclogh, Co. Clare.
A Natura Impact Statement was submitted along with other documentation in support of the application
Proposal was for:
Construction of a pumping station (underground chambers (3.5m x 4m wide x 4m deep), control kiosk 2m3, concrete hardstanding 300m2, mesh fence to surround and screen planting), • Construction of a rising main (pipe 550mm diameter x 700m long buried within a trench) between the pumping station and outlet, • Construction of an inlet and outlet chamber at Poulnaclogh/ Mucknish Bay with overflowing weir, • All other associated works.
Note: The NIS refers to an associated feasibility study and preliminary design report by Hydro Environmental Ltd, which is not included with the application
Assess and develop a viable, cost-effective and sustainable Scheme, to allow the design flood event along the Bantry & Mealagh Rivers and their tributaries without causing flooding of properties, in so doing protecting against flooding from pluvial, fluvial, groundwater, tidal and surge.
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.
Preparation of the Appropriate Assessment Screening Statement.
Public consultation, including Public Information Days. The purpose of the first Public Information Day is 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.
Development and identification of preferred scheme, informed by: Multi-criteria assessment of options including environmental assessments Cost Benefit analysis for the preferred scheme
Stage 2: Planning process
Complete the necessary planning and any other statutory processes, to progress the preferred Scheme through Part 10 Planning under the Planning and Development Act 2000 or confirmation under the Arterial Drainage Act 1945.
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 where relevant. 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
A Natural Water Retentions Measure (NWRM) Feasibility Assessment will be undertaken when assessing the solutions to mitigate flooding in Bantry. Where it is feasible for NWRM to contribute to flood reduction in the Scheme Area, or to contribute to the mitigation of the environmental impacts of the Scheme, these measures will be developed as part for the Scheme.
South West Catchment Flood Risk Assessment and Management (CFRAM) Study
Parts of Bantry have been identified as being at risk of flooding. The areas at risk in particular follow the path of the Mill River, Alley River and Scart Stream through the town and the Mealagh River to the north of the town.
Bantry is also affect by tidal flooding with coastal areas identified as at risk. There are also problems with the poor structural condition and flow capacity of culverts in the town. One of the significant causes of flooding is high tides entering the local drainage network and causing sewer flooding as well as river flooding from the Bantry Stream and tributaries. Bantry is prone to flash flooding from the numerous small steep rivers that flow through the town.
The Natural Water Retention Measures (NWRM) Working Group was established to advise the National Technical Implementation Group of the Water Framework Directive on the use of NWRM through Nature Based Catchment Management Solution [NbCMS]. The working group met three times in 2019 and once in 2020. The working group produced two reports, ‘Overview and Recommendations for Use in Ireland’ and ‘Evidence and Opportunities for use in Ireland’. These reports were both finalised in 2020 and presented to the National Technical Implementation Group for their consideration
Please provide the Minutes of the Committee and any documents circulated.
Please provide copies of ‘Overview and Recommendations for Use in Ireland’ and ‘Evidence and Opportunities for use in Ireland’.
The OPW considers that improvements could be made to its economic assessment of flood relief schemes. This includes that the widest possible range/scope of relevant benefits of such schemes are captured and represented in the business case and that the OPW uses the most appropriate economic appraisal to inform progressing investment in these schemes
The following project objective was agreed with the Steering Group.
To inform the OPW’s €1bn planned investment in approximately 150 flood relief schemes over the National Development Programme 2018-2027, prepare a report detailing the recommendations and options for economic appraisal with reference to the Public Spending Code for appraising government investment in flood relief schemes.
Economic Appraisal of Flood Relief Schemes Implementation Plan
The purpose of this report is to set out an outline plan for the implementation of the recommendations set out in the Mott MacDonald authored report Options and Recommendations for the Economic Appraisal of Capital Flood Relief Schemes
