Milne is also executive chairman of contractor the Stewart Milne Group.
The new stadium site is adjacent to the Aberdeen – Westhill road and replaces previous relocation plans for a new ground at Loirston.
Milne said: “Kingsford offers an opportunity to locate both the stadium and the training facilities within a single site, as was the original plan for Loirston, and it is in an ideal location for supporters travelling from all areas in and around Aberdeen.
“Crucially, we have full control of the site via a concluded missive with the landowner.
“Extensive site diligence has already been carried out at Kingsford to establish the feasibility of the land area and also the requirements for the planning process.
“AFC and Aberdeen City Council see a new stadium and training facilities as a vital part of the region’s infrastructure, and there is a strong desire by the Club to deliver these new facilities as soon as possible.”
The club plan to have the training facilities operational by 2018, with the new stadium following in season 2019-20.
Milne added: “There will be a twelve week period of public consultation, after which initial planning for the training facilities will be applied for, with the outcome expected later this year.”
