Chantry Cottages Critical Flood Defence Works

  • Client: The Environment Agency
  • Delivered by: JBA Bentley
  • Location: Goole, Humberside
  • Value: £6.3m

A significant number of our schemes involve working with clients such as the Environment Agency to implement preventative measures to guard against issues such as flooding. This was the case at Goole, where concerns were raised about the stability of the channel bank and foreshore of the Dutch River.

A tidal surge in early December 2013 caused widespread disruption along the east coast, with many properties flooded and extensive erosion of coastal areas. The surge entered the Humber and associated rivers, filling the River Ouse and then entering the Dutch River.

The Dutch River itself is narrow and constrains flows, resulting in a large tidal range with high velocities. Having identified the unstable banking on this stretch of river, JBA Bentley was engaged by the EA to deliver a three-phase scheme to reduce the risk of flooding to surrounding areas and properties at times of high tides.

The solution has seen us construct a permanent flood defence using a combination of sheet and Continuous Flight Auger (CFA) piling, steel tendons and rock armour to reinforce the embankment. On this scheme, temporary works were crucial in enabling the permanent works to be delivered safely. Over £1m was invested in temporary works at Chantry Cottages, including 25,000 tonnes of stone used for ramps and piling platforms, of which some has been reused on other schemes.
