The Topeka school district hopes to buy 128 acres that once were part of the grounds of a state hospital for the mentally ill.
The district already owns 60 acres of the former Topeka State Hospital grounds and built a sports park there.
The district says it is in the final stages of negotiating a $2.3 million sale.
Associate Superintendent Mike Wilson says the district could create a campus to train students for renewable energy jobs.
Wilson said other possibilities include a child care center for school employees and dorm space for student teachers. And the district could move its headquarters.
The hospital closed in 1997 in a push by the state to treat the mentally ill in the least restrictive environments possible.
