Overview
Westmeath County Council in partnership with The Office of Public Works (OPW), have commissioned the Athlone Flood Alleviation Scheme to address flooding in the town.
Objectives and Project Need
The overall objective of the works is to implement a Flood Alleviation Scheme for Athlone town that will ensure that properties and people are protected insofar as possible from the effects of flooding from the River Shannon and its tributaries.
Athlone has been subject to acute fluvial flooding in the past mainly from the Shannon and its tributary, the River Al, which flows through the east of the town. This flood risk is well documented and has been subject to hydrological and hydraulic analysis, flood risk assessment and development of a preferred option through the Shannon CFRAM Study.
How the work is being delivered
The Option Appraisal Report for Athlone Municipal District has identified eight discrete cells of
flood defence works:
- Deerpark – Permanent embankment along Shamrock Lodge to Lock Gates.
- Strand – Permanent flood wall between Burgess Park to Bridge (East side).
- Quay – Permanent flood wall from Lock Gate to Bridge (West side).
- Brick Island – including Jolly Mariner and Priory Park – A combination of permanent flood walls and embankment.
- Marine View – A combination of flood walls and permanent embankments.
- Iona Park – Permanent embankment and raised roads.
- Golden Island – Permanent embankments, raised road and flood wall.
- River Al (Cregan) – Provision of storage upstream of the N6 to attenuate flows in flood conditions.
Proposed Solution
The work for each cell will comprise four stages, as follows:
Stage I: Development of a number of flood defence options and the identification of a
preferred Scheme.
Stage II: Outline Design and Planning including an Appropriate Assessment (AA) (If
deemed necessary) and Environmental Impact Statement (If deemed necessary) where required.
Stage III: Detailed Design & Construction.
Stage IV: Handover of Works.
It is proposed that the projects will be delivered in a phased manner with cells progressing to planning and construction once all required studies and investigations have been completed to ensure works are completed in a timely fashion.
