Yes, if your site is in or near an area at risk of flooding, or Cavan County Council has requested flood risk information at Further Information stage. Objective FRM 03 of the Cavan County Development Plan 2022–2028 states that a site-specific Flood Risk Assessment is required for all planning applications in areas at risk of flooding, applying the 2009 Planning System and Flood Risk Management Guidelines. In Cavan that usually means the River Erne, Lough Oughter and the Annalee.
Flood Risk Assessment for Cavan Planning Applications
If you're submitting a planning application to Cavan 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 Cavan County Development Plan 2022-2028 and the Planning System and Flood Risk Management Guidelines.
Cavan's flood risk is dominated by the River Erne system and its lakes, including Lough Oughter, with the Annalee River adding risk in the east of the county. During Storm Desmond in December 2015, flooding from the Erne, Lough Oughter and the Annalee affected the area around Cavan Town. Cavan County Council's SFRA identifies flood-affected lands in Cavan Town and Belturbet, and the plan requires flood risk assessment in peatland and wetland areas as well as mapped flood zones.

- Annalee River
- Cavan Town flood zones
- Belturbet and the Erne corridor
- Peatland and wetland sites
What's Included
Every FRA we complete for Cavan 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 Where data is limited or outdated, we undertake bespoke hydraulic modelling (1D/2D HEC-RAS).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 & River Analysis
Erne system lake levels and river flood levels, with climate change allowances and long-duration flooding considered.
FFL Comparison
Your proposed finished floor levels compared against design flood levels plus freeboard.
Development Plan Compliance
Explicit demonstration of compliance with Cavan County Development Plan flood risk policies.
Further Information Requests
Received an FI request from Cavan County Council asking for flood risk information? We regularly handle urgent FI responses for Cavan sites. Typical turnaround is 7–10 working days — often faster for straightforward sites.
Key Documents for Cavan Flood Risk Assessments
Every FRA we prepare for a Cavan 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:
Cavan County Council
- Cavan County Development Plan 2022–2028, incorporating a Local Area Plan for Cavan Town (as varied)
- Consolidated Strategic Flood Risk Assessment Report for Variation No. 1, Cavan County Development Plan 2022–2028 (August 2026)
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)
- OPW / gov.ie – Consultant engineers appointed for the Cavan Town Flood Relief Scheme

Cavan Flood Risk Assessment FAQs
What does Cavan County Council require?
Objective FRM 03 of the Cavan County Development Plan states that a site-specific Flood Risk Assessment is required for all planning applications in areas at risk of flooding, and Objective FRM 08 extends this to development in peatland and wetland areas.
Is there a flood relief scheme for Cavan Town?
Yes. The OPW-funded Cavan Town Flood Relief Scheme is at design stage and is intended to protect around 110 properties. Until it is built, Cavan Town sites are assessed against current flood levels with climate change allowances.
How are Erne lake levels assessed?
For sites near Lough Oughter and the Erne lakes we use OPW modelled flood levels where available and the council's SFRA flood zones, with climate change allowances. Lake floods rise slowly and last a long time, so access and egress are an important part of the assessment.
Can I get planning permission in Flood Zone A in Cavan?
Possibly. Under the 2009 Guidelines, highly vulnerable development such as housing in Flood Zone A must pass the Development Management Justification Test, and Cavan 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 Cavan?
Typically 7–10 working days from instruction for a Stage 2 assessment, and often faster for straightforward sites. If Cavan 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.
