10-year construction plan to combat failing sea walls and eroding beaches
Chichester District Council has kicked off early market engagement for a £108m coastal defence scheme in Selsey on the Manhood Peninsula in West Sussex.
The Selsey Coastal Scheme will overhaul the ageing sea walls, groynes and beach defences protecting the peninsula’s low-lying coastline.
With existing structures increasingly prone to failure, the council is advancing a full-scale capital works programme planned to run from 2030 to 2040.
Prior to the construction of the existing sea wall in the 1950’s, Selsey was reported as one of the fastest eroding coastlines in England.
A feasibility study completed in 2023 backed the viability of a major scheme, leading to successful funding for the current options appraisal and outline design stage.
Early designs from consultant Royal Haskoning DHV propose encapsulating or replacing the current reinforced concrete sea walls and timber groynes, particularly along East and West Beaches.

To shape the delivery approach, Chichester council is calling for contractors with experience in large-scale coastal and civil engineering to register interest in a preliminary market engagement process running until 2 May 2025.
Engagement activities will include site visits, workshops and virtual sessions to explore constructability, programme sequencing, temporary works, and cost benchmarks.
Interested firms should email the council to register.
