Gainesville City Schools employees will get 3 percent raises for 2016-17 and the school district will spend $66.4 million for its general fund — using about $1.7 million in reserve funds — under a tentative budget adopted unanimously Monday. The board is expected to hold budget hearings at 4 p.m. and 5 p.m. May 23. A video with information about the budget is expected to be on the school system’s home page at its website by Wednesday.
