A 1-in-100-year flood defense is needed to protect residents, visitors, properties, and the environment at Portsea Island.
The coastal scheme upgrades and replaces ageing and inadequate defenses and is designed to reduce the risk of flooding from the sea for the next 100 years, protecting over 4,000 homes and 500 businesses.
AtkinsRéalis was appointed in 2019 by Coastal Partners, acting on behalf of Portsmouth City Council, to provide commercial and cost management on the coastal flood defense scheme.
The six-year project forms phases 4a and 4b of the wider North Portsea coastal scheme. The Eastern Road and Kendall Wharf segment comprises the installation of a 2km sea defense wall, the construction of an embankment and the raising of the access road.
AtkinsRéalis’ specialist Southampton-based marine/coastal cost management team are working closely with Coastal Partners to manage project budgets, ensuring that all post-contract prices are efficiently scrutinized, monitored, and managed.
Although the project experienced covid-related delays that impacted costs, the project is progressing well. AtkinsRéalis used our expertise in coastal defense cost management to challenge costs, where appropriate and investigate compensation events as instructed to protect our client’s interests.
We oversaw the management of the contractor’s costs and were asked to assist in the review of all compensation events resulting in further financial benefit.

North Portsea Project Manager at Coastal Partners
The project not only provides the required flood protection, but also significantly enhances the locality, including landscaping with wildflowers and tree planting, creating areas of seating, a wider footpath and incorporation of sections of glazing in the sea wall to maintain views for the public and from existing sailing clubs, outdoor activity centers and a caravan park.
Environmental considerations have been a foremost consideration with reduced winter working to encourage over wintering birds and foreshore reinstatement to promote the marine environment.
New standards in coastal defense will be achieved via the pioneering textured finish on the concrete portion of the sea wall. This demonstrates the UK’s first large-scale application of a textured sea wall specifically designed for inter-tidal ecology, improving habitats for marine plants and animals.
The surface is created by using an Eco Formliner and was developed by Coastal Partners in partnership with the University of Glasgow and Bournemouth University. The project partners were delighted when the Eco Formliner won the Coastal Management Award at the Environment Agency’s 2022 Flood and Coast Awards.
The Eastern Road project is due to be completed in 2024, with further ongoing landscape maintenance until 2026.
Our priority is ensuring that Coastal Partners and Portsmouth City Council achieve best value for this publicly-funded project. This is a notable example of our specialist cost management service for coastal protection schemes.
