Environmental Accolade for Shoreham Adur Tidal Walls Scheme

A scheme which has significantly reduced flood risk to thousands of properties on the West Sussex coast has been recognized with a prestigious environmental award, Mackley reports. 

The Shoreham Adur Tidal Walls Scheme, officially opened in March 2019, was presented with a Green Apple Environment Award on 25 November.

The Shoreham scheme was carried out by Mackley, working as part of Team Van Oord and on behalf of the Environment Agency, Coast to Capital Local Enterprise Partnership, Adur District Council and West Sussex County Council.

Construction of the new 7.2km tidal defenses in Shoreham began in September 2016, as many of the old defenses came to the end of their useful life.

The new defenses cover 1.8km on the east bank of the River Adur between Coronation Green and the A27 road bridge – and 5.4km on the west bank between the river mouth and the A27 road bridge.

They are formed of embankments, sheet pile walls, rock revetments, flood glass, and property level protection, and are designed to last for 100 years – though have been built so that they can easily be further raised after 50 years if necessary.

The project also involved improving the public footpaths along the route of the defenses, and approximately 1.4 hectares of compensatory saltmarsh habitat have been created.
