SOUTHSEA COASTAL SCHEME
The Southsea Coastal Scheme is the UK’s largest local authority-led coastal defences project, worth more than £185M. 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.
