A planned Foxconn manufacturing facility in southwest Wisconsin could cost taxpayers roughly $4.5 billion, a state assemblyman said Tuesday.

Wisconsin Assemblyman Gordon Hintz (D) told reporters that a memo from the state legislature’s fiscal bureau indicated the cost of the facility to the public will likely be higher than the $3 billion Gov. Scott Walker (R) projected last year.

The $4.5 billion mostly consists of costs to state government through tax credits the state granted Foxconn over a 15-year period. Other factors included are utility costs, road improvements and local government grants, according to the State Journal.

Walker has said the the manufacturing facility could employ as many as 13,000 people.
