Microsoft's Project Alluvion campus in West Des Moines, Polk County, sits at 550 SE White Crane Road on a 154-acre site, partly former Willow Creek Golf Course land. Announced in 2014 as a $1.1 billion investment, it was planned at about 1.2 million sq ft. Iowa DNR permits it under the name Willow Creek, jointly with the neighboring Ginger East campus, as an existing data center with Cummins diesel emergency engines (Title V permit 24-TV-005). MidAmerican Energy serves the site. Incentives included a $20.3 million state sales tax rebate.
