Racine County has approved Microsoft's application to increase its Mount Pleasant, Wisconsin, data center campus by 1,030 acres.
Regional economic development officials on November 10 announced Microsoft's plans to purchase the remainder of the parcel where it was building data centers, as well as parcels to the west and north of the site previously controlled by Foxconn.
Combined with the existing 315 acres Microsoft purchased, the company will now own around two square miles of the business park in Wisconsin.
The $100m land sale was approved unanimously by the board. Microsoft has said that the development will look like a distribution warehouse, and it will invest billions more in new development.
County executive Jonathan Delagrave called the board's vote "a historical day in Racine County."
"This opportunity provides one of the most successful, environmentally conscious, great employers for its employees to be right here in Racine County."
Microsoft has until 2028 to build a campus valued at $1.4 billion, reports the Milwaukee Journal Sentinel. If they fail to meet this deadline, the company will be liable to pay money to the county.
Similarly, four buildings must be built or under construction by 2044.
Construction is already underway on the first data center which is located at County KR and 90th Street and the contractor, Walsh Construction, has permits to begin the second building. These two buildings alone will cost Microsoft around $1 billion.
