More than seven kilometres of new river and sea defences helping keep the community of Shoreham safe from flooding from storms and rising sea levels have been officially opened.

The new £45 million Adur Tidal Walls scheme will better protect over 2,300 homes and 169 commercial properties, as well as important local infrastructure such as the road network, railway line and Shoreham Airport.

Spanning 7,200 metres along the banks of the river Adur with 1.8km of new defences on the east bank between Coronation Green and the A27 road bridge, and 5.4km on the west bank between the river mouth and the A27 road bridge.

The majority of the project has been funded by a £37.4 million contribution from government, alongside contributions from Coast to Capital LEP, West Sussex County Council and a number of private developers through Adur District Council.

Sir James Bevan, Chief Executive of the Environment Agency, attended an event to officially open the scheme today (Friday 22 March) along with representatives from the community.

Cllr Neil Parkin, Leader of Adur District Council and member of the Greater Brighton board, said: “The Adur Tidal Walls scheme will have an immeasurable impact on the residents and businesses in Shoreham and Lancing. It will not only will protect our communities from future flooding but it also gives investors certainty, supporting the creation of new homes and workplaces while opening up the riverside to local residents.

“I want to thank the Environment Agency and their contractors for the work over the past couple of years. The complex scheme has presented a number of challenges and there is still the issue of completing the defences at the Sussex Yacht Club site to resolve.”

The old flood defences varied in height and many were coming to the end of their design life.

The new defences are formed of embankments, sheet pile walls, rock revetments, flood glass, and property level protection, and are designed to last for 100 years, with the option of being raised further to add even greater protection into the future.

As part of the project, the Environment Agency has also improved public footpaths along the route of the defences.

The new defences are made up of over 15,000 bricks, 800 m3 of concrete and 6,845 tonnes of rock. The project has also created approximately 1.4 hectares of compensatory saltmarsh habitat for the benefit of local wildlife.

Sir James Bevan, Chief Executive of the Environment Agency said: “This new scheme represents a remarkable feat of engineering which will see Shoreham better protected from flooding over the course of the next century.

“The Environment Agency has worked closely with partners and the local community to build and upgrade 7 kilometres of new and existing flood walls, embankments and other defences, bringing greater peace of mind to thousands of homeowners and well over one hundred businesses in the local area.”

Jake Berry MP, Minister for Local Growth, said: “It is good to see how Coast to Capital have worked with the Environment Agency to protect local businesses at Shoreham through the reinforcement of flood defences along the River Adur.

“This will not only protect Shoreham harbour and airport but will also unlock the area for housing developments and employment space, supporting the local economy and opportunities for local people.”

The Environment Agency is investing £2.6 billion to better protect an additional 300,000 homes by 2021. Many of these flood and coastal schemes incorporate a range of measures including working with nature, alongside traditional engineering techniques.

Floods Minister Thérèse Coffey said: “I’m delighted to see the Shoreham Adur Tidal Walls flood scheme open, protecting over 2,000 homes and businesses and supporting crucial local infrastructure including Shoreham Airport.

“With £37.4 million of government investment representing over 80% of the total cost, the project showcases the very best of partnership working, demonstrating how government can work with its valued partners to continue to support local communities from flooding.”
