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.

Common Westmeath flood scenarios we assess:
  • 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
