Flood Risk Assessment, Wolsingham, County Durham
Jan 23, 2017

In October 2016 RAB Consultants completed a Flood Risk Assessment (FRA) in support of a proposed residential development at land in Wolsingham, County Durham.

The site is located to the north of the River Wear, which is classified as a main river. This watercourse was viewed as the primary flood risk to the site as identified in Environment Agency flood maps. National Planning Guidance 2015 dictates residential developments of this type also require supporting sequential and exception tests which were both developed by RAB along with the site-specific FRA.

Our assessment involved:

  • Data collection including hydraulic modelling

  • Liaison with the Environment Agency, the Local Planning Authority and Northumbrian Water

  • An assessment of the risk of flooding from all sources including fluvial, coastal/tidal, drainage, groundwater and surface water

  • Recommendations were provided, balanced against design / construction plans specified by the client
