Coastal defence management

How coastal defences are managed to protect Portsmouth from flooding and erosion.

Coastal Partners (formerly Eastern Solent Coastal Partnership) formed an alliance in 2012 to deliver a combined, efficient and comprehensive coastal management service across the coastlines of five Local Authorities: Havant Borough Council, Portsmouth City Council, Gosport Borough Council, Chichester District Council and Fareham Borough Council.

The innovative initiative was driven forward by a need for coastal management that recognises coastal flooding and erosion risk impacts are not exclusive to Local Authority boundaries.

The overarching vision of the Coastal Partners initiative is to reduce the risk of coastal flooding and erosion to people, as well as the developed and natural environment, by encouraging the provision of technically, environmentally and economically sustainable coastal defence and protection measures.

North Portsea Coastal Scheme: How Cockleshell Island got its name

The bird roost island near Eastern Road was named Cockleshell Island following a public naming competition. More than 240 suggestions were submitted by residents.

The winning name recognises both the Cockleshell Heroes, who trained locally before their Second World War mission, and the common cockle found in Langstone Harbour. The name reflects the island's purpose as a habitat for overwintering and wading birds that depend on the harbour's rich wildlife.
