All flood schemes go through a process of public consultation, engineering analysis, environmental assessment, and economic appraisal before agreement is made on a preferred set of options. The preferred options must then be approved by planning committees before any work can commence.
The Environment Agency gained planning permission in August 2024 by Burnley Planning Committee for the main Padiham Flood Risk Management Scheme (Sections 1-4 of the scheme). Section 5 has been de-coupled, and the design will be progressed separately. The next stage will be the approval of the full business case, before the Environment Agency can start on main construction works.
Two sections of the scheme have been constructed under the Environment Agency’s permitted development powers, while the remaining construction works will resume in Spring 2026 which can be seen below in the timeline of works.
As shown below in the timeline, the dates have moved slightly later from previous timelines as it has taken the Environment Agency time to fill the funding gap and to get the project team back together. The detailed design package of the scheme is underway and estimated to be finalised in August 2025. Following on from this, there are Environment Agency funding assurance steps that must be met before they can get in contract with the construction team in Autumn 2025. The construction of the Scheme will commence in Spring 2026 and be finalised before Winter 2028. The construction timeframe has been delayed due to:
- A high specification of the detail design package being produced, which gives the Environment Agency certainty over future costs.
- A realistic and robust programme being established. They have learnt lessons from other projects where early commencement with an incomplete design and substantial uncertainties led to unforeseen risks, additional costs, and longer construction times.
