Yes, if your site is in or near Flood Zone A or B, or Westmeath County Council has requested flood risk information at Further Information stage. The Westmeath County Development Plan 2021–2027 and its Strategic Flood Risk Assessment (Volume 7) apply the 2009 Planning System and Flood Risk Management Guidelines, so applications in or near flood zones need a site-specific FRA proportionate to the risk. In Westmeath that usually means the Shannon at Athlone and Lough Ree, the county's lakes, and the Inny and Brosna catchments.
Flood Risk Assessment for Westmeath Planning Applications
If you're submitting a planning application to Westmeath County Council and your site is in or near a flood zone, you'll need a Flood Risk Assessment that satisfies the requirements of the Westmeath County Development Plan 2021-2027 and the Planning System and Flood Risk Management Guidelines.
Westmeath's flood risk is dominated by the Shannon system along its western boundary, with Athlone experiencing significant flooding events. The county's numerous lakes — Lough Ree, Lough Ennell, Lough Owel, Lough Derravaragh — create localised flood risk, while the River Inny and Brosna catchments affect the northern and southern parts of the county respectively.
- Shannon corridor flooding (Athlone and environs)
- Lough Ree shoreline developments
- Lakeside sites on Lough Ennell, Owel, Derravaragh
- River Inny and Brosna catchment flooding
- Mullingar town flood zones
What's Included
Every FRA we complete for Westmeath sites includes:
Stage 1, 2 & 3 Assessments
Proper methodology using OPW flood mapping and modelling data. Where data is limited or outdated, we undertake bespoke hydraulic modelling (1D/2D HEC-RAS).
Lake Level Analysis
For lakeside sites: historical lake levels and flood extents with appropriate climate change allowances.
FFL Comparison
Your proposed finished floor levels compared against design flood levels plus freeboard.
Development Plan Compliance
Explicit demonstration of compliance with Westmeath County Development Plan flood risk policies.
Further Information Requests
Received an FI request from Westmeath County Council asking for flood risk information? We regularly handle urgent FI responses for Westmeath sites. Typical turnaround is 7–10 working days — often faster for straightforward sites.
Key Documents for Westmeath Flood Risk Assessments
Every FRA we prepare for a Westmeath site is assessed against the development plan and Strategic Flood Risk Assessment (SFRA) of the relevant planning authority, the national flood risk guidelines, and the latest OPW flood data:
Westmeath County Council
- Westmeath County Development Plan 2021–2027
- Volume 7: Strategic Flood Risk Assessment (with interactive flood map viewer)
National guidance and flood data
- The Planning System and Flood Risk Management – Guidelines for Planning Authorities (DoEHLG & OPW, November 2009)
- The Planning System and Flood Risk Management – Technical Appendices (November 2009)
- Circular PL 2/2014 – Flooding Guidelines (revised Section 5.28 on minor development)
- OPW Flood Maps – floodinfo.ie (CFRAM, NIFM and NCFHM flood mapping)
Links open the official source documents. Development plans are periodically varied, so we always check the current version and any variation SFRA when preparing your report.
Westmeath Flood Risk Assessment FAQs
How are lake levels assessed for lakeside sites?
For sites on Lough Ree, Lough Ennell, Lough Owel or Lough Derravaragh, we use OPW modelled or recorded lake levels where available, the flood zone mapping in Westmeath County Council's SFRA, and an appropriate climate change allowance. Lake flooding is slow-rising and long-lasting, so access and egress during prolonged events is a key part of the assessment.
Why is Athlone treated as a higher-risk area?
Athlone sits on the Shannon at the outlet of Lough Ree, where winter flood levels can stay high for weeks. The Shannon CFRAM study and Westmeath County Council's SFRA map extensive Flood Zone A and B areas in and around the town, so riverside and low-lying sites need a site-specific FRA.
Which flood data is used for Westmeath sites?
Design flood levels from OPW CFRAM and NIFM mapping on floodinfo.ie, checked against the SFRA's flood zone mapping and the council's interactive flood map viewer. For unmodelled streams, we undertake hydraulic modelling.
Can I get planning permission in Flood Zone A in Westmeath?
Possibly. Under the 2009 Guidelines, highly vulnerable development such as housing in Flood Zone A must pass the Development Management Justification Test, and Westmeath County Council will expect a site-specific FRA to show the development, its occupants and its access are safe without increasing flood risk elsewhere. Minor development such as small extensions, small-scale infill and changes of use is treated differently under Circular PL 2/2014: the Justification Test does not apply, but a commensurate flood risk assessment is still required.
How long does a Flood Risk Assessment take in Westmeath?
Typically 7–10 working days from instruction for a Stage 2 assessment, and often faster for straightforward sites. If Westmeath County Council has issued a Further Information request with a deadline, tell us when you get in touch and we will prioritise it. Stage 3 assessments with hydraulic modelling take longer and are scoped per site.
