Portsmouth City Council has selected Knights Brown to carry out the fifth and final phase of the North Portsea Coastal Scheme, starting in September.

Knights Brown previously constructed the second and third phases, so have carried out the majority of this valuable scheme.

The scheme as a whole, is one of the largest local authority-led coastal flood defence projects in the UK and is crucial for the protection of Portsmouth residents. The defences will safeguard more than 4,000 homes and almost 500 businesses. In total, it covers 8.4km of coastline from Tipner through to Milton. Most of the area is low-lying and many of the current coastal defences were approaching the end of their effective lives.


The final phase of works will take place along Ports Creek in North Portsea and will include 1.9 km of flood defences. The design consists of a sloped earth embankment, which provides the required flood defence level, with a rock armour toe. Rock armour dissipates wave energy, therefore preventing further breakup of the shoreline.

Divisional Director, Mike Crook, said: "We are delighted to have been appointed as principal contractor to carry out the fifth and final phase of the North Portsea Coastal Scheme. This third award demonstrates our capability and trusted collaborative relationship with Coastal Partners.

"Our extensive expertise in coastal civil engineering and our local knowledge will enable us to deliver this essential flood defence scheme, which will safeguard residents and businesses for the next 100 years. All of the improvements will be delivered with the highest standard in order to foster the growth of local marine life and enhance the social space for the local community."
