The partnership and the Environment Agency have proposed estuary restoration, and have been talking to residents, businesses, and visitors about how to proceed in the future.

Presently, a shingle beach and raised river banks prevent seawater from penetrating the uppermost[citation needed] areas of the Cuckmere Valley.

But the Environment Agency projects that an expected sea level rise due to climate change will increase the already steep costs of physical reinforcement, and current measures will not be sufficient.

They intend to stop repair of the levees and to allow the cycle of natural processes, including periodic flooding of the area.

The planning collaborators believe that in the long term, restoration of the saltwater estuary and marshes will enrich the ecological habitat, attract more wildlife and improve tourism.
