Flood Risk Assessment, Gowdall Green, Bentley, South Yorkshire
Jan 4, 2016

RAB Consultants has completed a Flood Risk Assessment in accordance with National Planning Policy Framework in support of a proposed residential development at Bentley in South Yorkshire.

The development site is located in Flood Zone 3 in accordance with the Environment Agency’s Flood Map for Planning (Rivers and Sea); therefore requiring a Flood Risk Assessment for this site.

RAB Consultants carried out both a site visit to assess the flood risk within the local area and a topographic survey to establish ground levels across the proposed site and along potential evacuation routes from the site. Our assessment to meet the requirements of the National Planning Policy Framework also involved:

  • Data collection, including the Environment Agency’s most recently modelled flood data for Ea Beck and Langthwaite Dike/ North Swaithe Dyke in Bentley
  • Liaison with the Environment Agency and Doncaster Metropolitan Borough Council
  • An assessment of the risk of flooding from all sources including fluvial, surface water, groundwater and drainage related; in accordance to Doncaster Metropolitan Borough Council’s SFRA.

A flood warning and evacuation plan is included in the assessment, ensuring that future residents are aware of the flood risk and indicating the most appropriate evacuation route to higher ground in Flood Zone 1.
