Multi-Party Framework Agreement for the preparation of Surface Water Management Plans (SWMP) for Fingal County Council

adminLeave a comment

To establish a Multi-Party Framework for Engineering Consultancy services for the preparation of Surface Water Management Plans (SWMP) for Local Area Plans (LAP), Masterplans, Urban Frameworks and other study areas;

Surface Water Management plans will consist of two key integral parts;

1. Preparation of Strategic Flood risk assessments in accordance with the “Planning system and Flood risk Management Guidelines for Planning Authorities”. This will include for all relevant stages of flood risk assessment as outlined by the Guidelines. 

2. Preparation of Sustainable Drainage Strategies (SDS) for the sustainable development of lands under consideration for development. The strategies will be an example of best practice in the use of sustainable drainage systems (SuDS)/Nature Based Solutions. As set out in the Fingal County Development Plan, it is an objective of Fingal County Council to encourage, promote and implement sustainable drainage systems (SuDS) on all new developments throughout the county and to encourage where feasible the retrofit of sustainable drainage systems within existing developments. The Sustainable Drainage Strategy will examine the feasibility of using all SuDS solutions including, swales, permeable pavement, rainwater harvesting, tree pits, green and blue roofs, detention basins, ponds and wetlands amongst other SuDS devices. The SDS must comply with the Fingal County Council Green Blue Infrastructure Guidance and the Dept of Housing Nature Based Solution Guidance 2022.

http://www.bantryfrs.ie/

The project shall comprise up to five stages.

Stage 1: Scheme Development and Design

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

Further detail is available on www.floodinfo.ie

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.
