ST. PAUL, Minn. (AP) _ An eastern Minnesota county has approved a mixed-use development at a former ammunition plant on a large swath of suburban land that's sat empty for more than 40 years.

The Ramsey County Board agreed on Tuesday to sell the former Twin Cities Army Ammunition plant to developer Alatus, LLC for nearly $63 million.

A proposal calls for the company to acquire the property in five phases between 2020 and 2034. Plans for the new development to be called Rice Creek Commons include three residential neighborhoods, parks, and retail and office space.

The former factory began churning out .30- and .50-caliber ammunition during World War II, and closed in 1976.
