Works to target Chesham flooding hotspot begin

Buckinghamshire Council will shortly restart planned works to make improvements to a well-known flooding hotspot in Chesham.

Flood management works to the culvert at Pednormead End will begin on Monday 27 June. The works form part of the Pednormead End Flood Management Scheme, a project for the local community of Pednormead End. It is part of a programme of capital flood management schemes being implemented by the council's strategic flood management team.

This area of Chesham has a long history of localised flooding caused by periods of heavy rain and high ground water levels. To address this issue, the existing piped culvert that carries the river under the Missenden Road is to be replaced with a precast concrete culvert. The design has been carefully considered to make sure the size of the new culvert is suitable to fit into the restricted space available and to ensure that it doesn't push more flood water downstream. In addition, a section of the Bury Pond culvert that runs under Church Street near the Queen’s Head Pub will also be repaired.

Completion of the project has been hindered by both weather conditions and the complexity of the task. The first stage of the project, which focused on lowering and diverting utility services ahead of the culvert replacement, began in June 2020. However, high ground water levels have twice delayed the completion of this initial stage of work.

Works are now scheduled to restart on Monday 27 June and will take around 12 weeks to complete. The work will take place in three phases:

  • Phase 1 (27 June to 4 August): Diversion of an underground high voltage electricity cable and repair of a damaged section of the Bury Pond culvert that runs under Church Street near the Queens Head Pub
  • Phase 2 (5 August to 18 August): Replace the existing River Chess culvert from its outlet adjacent to the Queens Head Pub to the Missenden Road/Wey Lane junction
  • Phase 3 (19 August to 16 September): Replace the existing River Chess culvert from the Missenden Road/Wey Lane junction to its inlet adjacent to house number 5 Missenden Road

Local residents and businesses have been given advance notice of the works and will be kept informed throughout if there are any necessary alterations. During the works a 24-hour road closure will be in place at the junction of Missenden Road, Church Street, Pednormead End and Wey Lane, along with a signed diversion route. Pedestrian access will still be available with any diversions clearly signed. The majority of the works will take place between 8am and 4pm Monday to Friday. Some exceptions will require work to take place outside these hours but all those affected will be notified in advance.

Gareth Williams, Cabinet Member for Climate Change and Environment said: “We appreciate the disruption that works of this nature can have for local residents and businesses and we apologise in advance for this. However, this work is vital if we are to address the wider issue of flooding in this area. The damage to homes and livelihoods caused by flooding cannot be underestimated and we have a responsibility to do what we can to make improvements and stop the flooding from recurring.”
