The Rosemount City Council on Tuesday night approved a deal that was years in the making that will allow Dakota Aggregates to mine nearly 900 acres roughly 25 miles southeast of the Twin Cities, the Rosemount Town Pages reports.

The council approved a large-scale mining permit for the company, which plans to begin mining in 2013 on the University of Minnesota-owned UMore Park property in southeast Rosemount, the newspaper reports. The deal allows up to 40 years of mining on the site.

The university has a broader vision for its 5,000-acre UMore property that includes a "unique, sustainable, University-founded community of 20,000 to 30,000 people, a 25- to 30-year endeavor."
