The plans include a seafront promenade, improved and refurbished car parks, a restored paddling pool, new toilets and new railings and bollards.
Work is expected to start this year and is scheduled for completion in 2008.
Plans are backed by the Castle Point Regeneration Partnership (CPRP) and Castle Point District Council, who are seeking the views of local people.
CPRP chairman Pam Challis said "The seafront is a priority area, so we must make sure we get this right."
The project would also refurbish the bandstand area of Canvey
Improvements will be made using one million pounds granted to the Partnership by the government.
Ms Challis added: "This is a place for everybody to enjoy and it is important for us to hear what the public think about this scheme."
The Castle Point Regeneration Partnership brings together all local organisations, working to improve Castle Point through long term regeneration.
It includes Castle Point Borough Council, Essex County Council, East of England Development Agency (EEDA), Thames Gateway South Essex Partnership, the Greengrid partnership and the RSPB.
