The Environment Agency and Arup are developing tidal embankment improvements between Barton and New Holland. Land requirements, habitat effects and possible separate Barrow Haven works shape the route to the 2027 business case.
Tidal embankment and outfall adaptation is the primary work classification. Related sectors connect this record to adjacent marine delivery and market coverage.

Arup - Full Business Case and detailed-design services
Contract route
Arup's Full Business Case contract began at the end of December 2025. The main construction programme remains in design and funding development.
Execution window
The owner targets the business case for summer 2027, preparatory elements from late 2027 and phased construction during 2028-29. Barrow Haven adaptation may follow a separate consent-led phase.
Works package
Raising and adapting tidal embankments, associated drainage and outfalls, and property flood-resilience measures, with possible separate Barrow Haven adaptation.
Marine interfaces
An inland embankment extension changes land requirements and habitat effects. Engagement with Natural England and the MMO is informing the design and licensing approach.
Commercial evidence boundary
The reported GBP 750,000 allocation supports continued 2026/27 development. Local council funding and the wider scheme estimate have separate scopes; construction quantities and access depend on the selected embankment footprint.
