Supporters of plans to revamp Shoreham Harbour and create thousands of jobs say their dream is not dead despite a huge cash shortfall.

Adur District Council pledged to come up with a workable option to save the Shoreham Maritime Vision, which Brighton and Hove City Council has branded unviable.

The harbour makeover could create 6,400 jobs and 1,200 homes but with costs estimated at more than £200 million, it is unlikely the regeneration in its current form could go ahead.

Plans to transform the port were drawn up in 1999 by several partners.

They were thrown into doubt when a study published last week by Brighton and Hove said the necessary transport improvements would be too costly.

The most likely options would be a new tunnel or a new link road to the A27.

Council officers discovered they would have to find £177.5 million for the tunnel, while the road link would leave them £92.5 million short.

None of the partners involved would be able to provide the funding needed to push ahead with the plans, which include an enterprise park and media village.

Councillors will consider the report on Tuesday.
