The land is the largest brownfield site in Derby and has been identified by the Council as a strategic development site and regeneration priority.
Network Rail will work with the selected development partner from the production of a master plan through to the planning process, completion of the site and the securing of occupiers for individual plots.
Proposals for the site will be considered on the grounds of overall benefit to Derby as a whole.
Stuart Kirkwood, head of development for Network Rail said: ‘We are always working to identify development opportunities where we can work in partnership with the private sector to develop non operational land.
“This site offers the potential to create new employment opportunities and support the wider regeneration plans for the area.’
The leader of the council, Councillor Philip Hickson said: “The site is a regeneration priority in the saved local plan in an area which focuses on business uses.
“The Chaddesden Triangle is part of the River Derwent corridor where recreational and leisure facilities are being enhanced. There are opportunities to deliver key regeneration benefits, taking advantage of this major river frontage, for the area and for the city. “
The deadline for initial responses will be 18 November 2011, with those shortlisted invited to make final bid stage tenders by January 2012.
It is anticipated that final developer selection will take place in March 2012.
