About the scheme
Mytholmroyd Flood Alleviation Scheme was developed by the Environment Agency in partnership with Calderdale Council, the local community, and partners. VBA, a joint venture comprising VolkerStevin, Boskalis Westminster and SNC-Lavalin’s Atkins business, were the main contractor responsible for its design and construction.
Vital works completed as part of the scheme include:
- New, raised flood and improved walls.
- The relocation of Caldene Bridge (this video explains why).
- Widening of the river channel at key locations.
- Waterproofing of buildings next to the river.

Following the devastating floods of Boxing Day 2015 and history of flooding in Mytholmroyd, it was important that a flood alleviation scheme was designed and constructed as quickly as possible. To develop the scheme at pace, many aspects of the programme including design work, community consultation, obtaining planning permission and ground investigation work all ran in parallel.
Whilst designing the scheme, work was carried out to protect the village including repairing damaged defences, removing blockages and installing new temporary defences. Data and evidence were gathered during the inspection process to help develop a better understanding of the catchment and produce computerised models to confirm how certain scenarios for flood risk measures will work.
