Longer-term (future phases)

Our coastline is constantly changing. Over the next century, rising sea levels and stronger storms will shape this area in significant ways.

Current projections suggest sea levels could rise by up to 1.15m by 2100, and storm patterns may become more severe. These changes will affect homes, businesses, nature, and the places we all value.

What’s happening now?

Early development of Phase 2 has started because the case for future investment is so strong.

  • We are requesting funding from government to commence this work, which could take up to two years to secure, followed by approximately ten years of appraisal and design.
  • Phase 2 will be a large and complex project and is scheduled to commence in 2037, following completion of Phase 1.
  • We will continue to work closely with local councils and communities to maximise alignment with their future plans and support wider priorities.

We are continuing to collect information on community aspirations for the coastline. Our findings from a survey we ran in summer and early autumn 2025, including what people value along the coastline and their hopes for the future, will be available early in 2026.

You can also explore our StoryMap to learn about the history of this coastline and review examples of coastal defence approaches from around the world. These types of interventions will be assessed for their economic, technical, and environmental suitability as part of Phase 2.
