The client for the scheme is a joint venture between Medway council, in partnership with the South East England Development Agency.
A Medway council spokesperson said: "We have decided to go out to tender for design work and a technical site investigation. Once we have appointed consultants we hope to submit an outline planning application at around the turn of the year. We then hope to market Rochester Riverside again."
The Rochester Riverside project is a 30 ha brownfield site on the River Medway in Kent. It had formerly been used to house gasworks, aggregate factories and waste deposits. It ran into difficulty because of the rising cost of remediation work.
The tender brief, posted this week in the European Union's Official Journal, called for a mixed-use community of around 1800 homes, with a hotel, primary school, community facilities and employment opportunities.
