Scheme Overview

Update Winter 2023 – The proposed Irwell Vale, Strongstry and Chatterton Flood Risk Management Scheme has been going through its appraisal in line with government guidance leading up to Outline Business Case (OBC) submission. Unfortunately, due to a significant gap of c.£9m in available funding, a decision has been made to halt the scheme. The Environment Agency and its partners understand this is extremely disappointing to all those involved in the scheme and in particular, the local residents of all three communities.

The Environment Agency appraised the flood protection options for the 3 communities. The appraisal consisted of the evaluation of a long list of options, community engagement, identification of the preferred option being ‘linear defences’, refinement of the preferred option including the identification of associated constraints and opportunities, and site surveys and investigations.

The Preferred option (linear defences) was determined by taking into consideration technical feasibility, cost, economic benefit, buildability and environmental impacts. The surveys included Heritage surveys, Environmental/Ecological surveys, topographical surveys and Ground Investigations. The output of these surveys and investigations were reviewed and informed further hydraulic modelling of the flood risk to the communities. The agreed final concept would have fed into an Outline Business Case which has to go through an assurance process internally.
