Flood Risk Assessment, Dunholme, Lincolnshire
Feb 1, 2015

A Flood Risk Assessment has been completed by RAB Consultants in support of a proposed residential development at a site in Dunholme. Although the development site is located in Flood Zone 1, in accordance with the Environment Agency’s Flood Map for Planning (Rivers and Sea), a Flood Risk Assessment was required for this development as it was over 1 hectare in size.

RAB Consultants carried out a site visit to assess the flood risk to this site in relation to local ground levels. Our assessment to meet the requirements of the National Planning Policy Framework also involved:

  • Data collection, including the Environment Agency’s flood map data for Dunholme Beck
  • Reviewing policies from Planning Practice Guidance 2014 relating to Essential Infrastructure
  • Liaison with the Environment Agency, The National Soils Research Institute (Soilscapes) and Anglian Water
  • An assessment of the risk of flooding from all sources including fluvial, surface water, groundwater and drainage related; in accordance to Sheffield City Council’s SFRA

Flood mitigation options were included in order to highlight measures to reduce surface water run-off rates at the site.
