The pitch would be used by players at SUFC, the club's football in the community scheme and will be available for public use.
The money is available as part of a pilot scheme from the Football Foundation to develop grass-root all-weather facilities.
At the moment when the training pitch alongside Glanford Park is waterlogged the first team have been left struggling to find somewhere to train, and this develpment would counter that problem.
The pitch will be built at GP, although the exact positioning will not be decided until funds have been secured.
The club have brought in former Mansfield, Hull and Doncaster midfielder Scott Maxfield to assist with the Football in the Community scheme, with Lee Turnbull taking the newly created role of Community Development Manager.
