Brynteg Coastal and Country Retreat is a holiday park run by Park Leisure in North Wales. During a period a sustained heavy rainfall in late 2017 a resulting flash flood overwhelmed the drainage culvert carrying a small watercourse through the site and caused extensive damage to the park.

Hydroplan was employed as a subcontractor to the main contractor, Lynwoods Building Consultancy, to carry out a Flood Risk Assessment (FRA) and provide a sizing for a replacement culvert.

The job comprised of two separate tasks. Firstly a desktop FRA was carried out so that a new culvert could be sized appropriately and installed immediately. Hydroplan then followed up with a site visit and investigation to provide suggestions for further mitigating the flood risk in the future.

Key Features:

  • Flood remediation
  • Estimates of return period floods
  • Culvert sizing
