The Environment Agency, Burnley Borough Council and partners have been working continually since 2017 then to develop proposals for the Padiham Flood Risk Management Scheme. This has included, but has not been limited to, flood modelling, site and ground investigations, environmental assessments, topographic surveys, community and landowner consultations, outline and detailed designs, gaining the necessary permissions for the works and securing further funding to pay for additionally identified work.
Site investigations have taken place over winter-spring 2021 to better inform the understanding of existing walls and old mines in the area. This identified significantly more challenging ground conditions than expected, which has led to further information being required and a second phase of ground investigation works in spring 2022. An understanding as to how this will affect the designs of the flood defences has been required which has impacted the design period. The Environment Agency have been working closely with specific landowners through this process.
Due to these issues, and the subsequent impact of the design process timeframe, the Environment Agency have identified sections of works that can be completed as permitted development rather than those that require formal planning permission. The Environment Agency have started on these areas first.
Gravel is monitored under Padiham Bridge (River Calder) and at Shakespeare Street Bridge (Green Brook) against agreed trigger levels for removal. Clearance has and will continue to take place as required at these locations when the trigger levels are reached.
Invasive Non-Native Species treatment of Japanese Knotweed has taken place in Padiham between summer 2021 and summer 2022, in preparation for the flood defence construction this summer.
