A multi-million pound bid for lottery cash could transform Blackpool's seafront into a living landmark of "fresh air, magic and fun" if successful.

The £21m bid, submitted by Masterplan regeneration company ReBlackpool to the Lottery's recently launched Living Landmark trust, would form part of the funding for a complete state-of-the-art"revamp of three kilometres of promenade between the resort's North and South piers.

The overall cost of the revamp scheme, which would feature a year round urban park for residents and visitors to mix fun, exercise and learning about the natural environment and Blackpool's social history, is estimated to cost £47m and would complement the rebuilding of the sea wall.

Additional funding for the bid is expected to come from the North West Development Agency, European Regional Development Fund and the British Arts Council.

Both ReBlackpool and Blackpool Council are urging residents to put forward their ideas to the scheme's team of professional designers and artists.

Director of development at ReBlackpool, Reg Haslem said: "The aim is to work with the people of Blackpool to develop ideas for creating a conspicuous, dazzling jewel, fusing past and present, myth and reality, fantasy and imagination.

"We are happy to entertain all sorts of wild and wonderful ideas for what we might include on the headlands and the rest of the promenade.

"In partnership with the local community, we will think the unthinkable to innovate, surprise and create spectacle.

"Nothing is out of the question - especially the out-of-the-ordinary. We want this project to fire people's imaginations and get them thinking about what the seafront could look like."

Cllr Eddie Collett, Blackpool Council's cabinet member for regeneration and tourism added: "I'm sure the prospect of getting involved in developing the seafront, which is at the heart of Blackpool, will interest many of our residents.

"We just have to hope that our bid makes it to the next stage."

ReBlackpool will now be visited by National Lottery representatives in April who will compile a shortlist of successful projects from across the UK in May.

If shortlisted, the town will then be given a sum of money to develop plans for the project by next January and will find out if they have been successful in securing the total amount by June 2007.
