The future of South Dakota's School for the Deaf campus in Sioux Falls is up in the air. The handful of students still attending classes there will be mainstreamed or sent to another state's residential program. The board of regents is reviewing its options with the property and buildings which are valued at about $10 million. That include leasing parts of the 14-acre campus or selling it. If they decide to sell, the state legistlature would have to approve of the deal and the proceeds will go to the School and Public Lands Endowment.
