Securing Southsea's future
The Southsea Coastal Scheme is the UK's largest local authority-led coastal defences project, worth around £180M. It will stretch for 4.5km from Old Portsmouth to Eastney, and help to reduce the risk of flooding to more than 10,000 homes and 700 businesses. Approximately 4,000 of these properties are at risk of direct threshold inundation.
Project Overview
The current defences are coming to the end of their lifespan, which increases the risk of flooding. We are creating new defences to embrace everything we all love about the seafront. The work will improve the seafront for future generations, while protecting the community and preserving the area's unique heritage.
