What we are doing
From Friday 25 July 2025 to Tuesday 31 March 2026, we will be building the permanent flood compensation area in the two fields east of Breakspear Road South and north of the Chiltern line, along the Celandine Route diversion. Access to the public footpath will always be maintained and traffic marshals will be stationed at crossing points to ensure safe access.
We will also be working on permanent fencing around the flood compensation area and the U46 footpath. These works will be carried out during our core hours Monday to Friday 8am to 6pm and Saturday 8am to 1pm.
The flood compensation area is designed to help prevent future flooding of the River Pinn in the area. During heavy rainfall, the flood compensation area will temporarily hold the extra water. Once the river level goes back down, the stored water will be safely released back into the river.
