Stallingborough Phase 3 Sea Defence Improvements - October 2026 Update

Works to restore the original capacity of the New Cut Drain outfall culvert have started. Specialist contractors are removing silt from a 1km channel across the foreshore to lower water levels and divers are making good progress clearing silt and debris from the culvert. Two new chambers are also being built to aid maintenance and safe access in the future. The installation of the new outfall flap valve will follow in due course before the end of October.

Works to remove the temporary widening of the embankment crest is nearing completion and landscaping at the Pyewipe end is expected to be completed during the Autumn. The coastal footpath should then be able to reopen.

The project team has secured the use of a compound at ABP’s Port of Grimsby to temporarily store spare rock, before the site compound is handed back to the landowners at the end of November. It is anticipated this rock will be reused on other local coastal schemes over the coming years.

The final works to complete Oldfleet Drain outfall and overflow are expected to begin soon, including the installation of water control devices and security fencing. This will provide additional flood resilience over the winter. Installation of the replacement Middle Drain flood gate may be delayed until 2027 due to design and manufacturing delays.

It was recently discovered that around 500m of rock amour toe, towards the northern end of the site, has become partially displaced. Investigations are underway to determine the cause and identify any necessary remedial works. As a result, construction is unlikely to be completed this Autumn and additional funding may be required. The project team is working to minimise impacts and secure the necessary consents, funding and resources .

The planned compensatory fish and eel habitat along the River Freshney to establish an improved habitat along a 500m reach upstream of Cromwell Road bridge in Grimsby has been completed.
