The Environment Agency (EA) says it expects construction of the Oxford Flood Alleviation Scheme to start in late 2026. Following approval of the Compulsory Purchase Order by the Secretary of State in May 2025, the EA is in the process of acquiring the land, and rights over land, needed to construct the scheme. Over the summer the Agency tendered for a construction partner and they expect to announce the company selected by the end of the year.
Outstanding issues
The project still needs to secure some approvals, including the formal planning permission. Oxfordshire County Council’s Planning and Regulation Committee resolved to grant planning permission last year, subject to the EA signing a Section 106 Agreement relating to biodiversity and habitat management and monitoring. The project team is working closely with the council to conclude this agreement, which they expect to do before the end of the year. The project will then need sign off on the Full Business Case from HM Treasury.
Community relations
The EA is planning to launch a Stakeholder Advisory Group to support engagement with residents. This group will be made up of local individuals who represent the community. They will provide advice and local insights as the project prepares for and begins construction.
The new construction partner will be appointing a Community Liaison Officer to ensure there is a named contact who can respond to immediate concerns relating to the construction site and escalate matters to the site manager and project team, as necessary.
On site activity
The project has been installing additional groundwater monitoring devices to collect groundwater data, and gauge boards to measure surface water levels. These will allow them to chart water levels before, during, and after construction of the scheme.
In August, a team surveyed for underground utilities, including electric cables and water and sewage pipes to prevent any disturbance of those assets while installing the new monitoring points.
